Immunization Update At its October 2012 meeting, the ACIP voted to recommend that healthcare personnel administer a dose of Tdap vaccine to pregnant women during each pregnancyideally at between 27 and 36 weeks gestationregardless of the womans prior history of receiving Tdap. – Reported cases of pertussis have spiked – Youngest infants are the most vulnerable – Vaccinating the mother during pregnancy can protect the youngest infants. – Tdap given at one pregnancy provides insufficient protection for subsequent pregnancies – Data support the safety of Tdap for pregnant women and their infants The CDC is expected to publish these recommendations in MMWR 2-22-2013
FDA Okays Pneumococcal Vaccine for Older Adults December 20, 2011 The FDA approved the pneumococcal 13-valent conjugate vaccine (manufactured by Wyeth Pharmaceuticals, marketed by Pfizer Inc) for adults aged 50 years and older for the prevention of pneumonia and invasive disease caused by the 13 Streptococcus pneumoniae serotypes contained in the vaccine. The move comes on the heels of the November 16, 2011, meeting of the FDA's Vaccines and Related Biologics Advisory Committee, in which the committee voted 14 to 1 in favor of expanding the indication for Prevnar 13 to adults.
CDC Recommends Immunocompromised Adults Get Prevnar 13 Vaccine June 21, 2012 the Centers for Disease Control and Prevention's Advisory Committee on Vaccine Practices voted 14 to 0 that adults "with AIDS, cancer, organ transplants, advanced kidney disease and other immune-weakening conditions" should be given pneumococcal vaccine Prevnar 13, including those "who've already had Pneumovax 23" The panel has not yet decided if "all adults 50 years old and older should get Prevnar 13."
ACIP Recommendations for PCV13 and PPSV23 Use Adults with specified immunocompromising conditions who are eligible for pneumococcal vaccine should be vaccinated with PCV13 during their next pneumococcal vaccination opportunity. Pneumococcal vaccine-naïve persons. ACIP recommends that adults aged 19 years with immunocompromising conditions, functional or anatomic asplenia, CSF leaks, or cochlear implants, and who have not previously received PCV13 or PPSV23, should receive a dose of PCV13 first, followed by a dose of PPSV23 at least 8 weeks later. Subsequent doses of PPSV23 should follow current PPSV23 recommendations for adults at high risk. Specifically, a second PPSV23 dose is recommended 5 years after the first PPSV23 dose for persons aged 19–64 years with functional or anatomic asplenia and for persons with immunocompromising conditions. Additionally, those who received PPSV23 before age 65 years for any indication should receive another dose of the vaccine at age 65 years, or later if at least 5 years have elapsed since their previous PPSV23 dose. – MMWR October 12, 2012 / 61(40);816-819
ACIP Recommendations for PCV13 and PPSV23 Use Previous vaccination with PPSV23. Adults aged 19 years with immunocompromising conditions, functional or anatomic asplenia, CSF leaks, or cochlear implants, who previously have received 1 doses of PPSV23 should be given a PCV13 dose 1 year after the last PPSV23 dose was received. For those who require additional doses of PPSV23, the first such dose should be given no sooner than 8 weeks after PCV13 and at least 5 years after the most recent dose of PPSV23. – MMWR October 12, 2012 / 61(40);816-819
CAPiTA Trial Preliminary Results The 85,000-patient study in the Netherlands, called CAPiTA, showed that Prevnar 13 prevented invasive pneumococcal disease, meaning infections of Streptococcus pneumoniae bacteria in patients age 65 and older. – 45.56% fewer first episodes of vaccine-type CAP among Prevenar 13-vaccinated subjects than in subjects who received placebo (P=0.0006). – Secondary objectives, the Prevenar 13 group experienced 45.00 % fewer first episodes of non-bacteremic/non- invasive vaccine-type CAP (P=0.0067) and 75.00 % fewer first episodes of vaccine-type IPD (P=0.0005) compared with the placebo group – To be reviewed by ACIP and FDA
Influenza Vaccine in Patients with Egg Allergy? The American College of Allergy, Asthma and Immunology "The very low risk of reacting to the injection is greatly outweighed by the risks associated with the flu." ACAAI recommends that those with a previous history of egg allergy get the injectable vaccine in a medical facility where any allergic emergencies can be recognized and treated if they occur. For those who have had serious reactions after eating eggs, the vaccine should be administered in an allergist's office. In the past, there was concern that because the flu vaccine is grown in eggs, residual protein could trigger a reaction in those with allergies.
Influenza Vaccine in Patients with Egg Allergy? June 21, 2012 The ACIP meeting marked the 1-year anniversary of a change in recommendations that removed egg allergy as a contraindication to influenza vaccination, and it does not appear that the modification affected the rate of allergic reactions, according to data from the Vaccine Adverse Event Reporting System (VAERS).
Influenza Vaccine in Patients with Egg Allergy? June 20, 2013 the ACIP recommended Protein Science's FluBlok for the 2013-14 season in a 13 to 0 vote for patients with a history of egg allergy. – A recently approved cell-based flu vaccine Flucelvax, made by Novartis, uses flu viruses grown in mammalian cells rather than chicken eggs and is thought to contain hardly any traces of egg. However, the vaccine seed strain used to make the vaccine is passaged in eggs, meaning it could contain a minuscule amount of albumin.
Influenza Vaccines for 2013-14 Influenza formulation changes for the 2013- 2014 vaccine have been announced. Trivalent vaccine (IIV3) will cover: – A/California/7/2009 (H1N1)-like virus; (H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011; and B/Massachusetts/2/2012-like virus. Quadrivalent vaccine (IIV4) will also include additional B virus coverage: – B/Brisbane/60/2008-like virus – Note that the FDA must first approve any changes before they can be made
Recently-FDA approved Influenza Vaccines for 2013-14 Season Quadrivalent Live-attenuated Influenza Vaccine (LAIV4)Flumist Quadrivalent (MedImmune) age 2- 49 (2 influenza A and 2 influenza B strains) Quadrivalent Inactivated Influenza Vaccine (IIV4) Fluarix Quadrivalent (GSK) age 3 and older and Fluzone Quadrivalent (Sanofi) age 6 mo and older both have (2 influenza A and 2 influenza B strains) Cell-culture based inactivated influenza vaccine (ccIIV3)Flucelvax (Novartis) age 18 and older Recombinant hemagglutinin vaccine (RIV3) FluBlok (Protein Sciences) age 18-49
Existing Influenza Vaccines for 2013-14? Fluvirin – II3/TIV by Novartis age 4 yrs and up FluLavel – II3/TIV by GSK age 18 yrs and up Afluria – II3/TIV by Merck age 9 yrs and up Fluzone High Dose – II3/TIV by Sanofi age 65 and older Fluzone Interdermal – II3/TIV by Sanofi age 18 to 64 yrs
Influenza Vaccine Efficacy Interim results for the 2013–14 season indicate that vaccination has reduced the risk for influenza- associated medical visits by approximately 60%. (MMWR 2-21-2014) Last year the vaccine was less effective and we now may know why? – A British Columbia research team found that mutations in the H3N2 virus occurred when a common strain of the virus chosen for the manufacture of a vaccine was modified. Although this so-called reference strain was initially well-matched to the virus it was intended to protect against, it had to be altered to grow better in chicken eggs to produce the vaccine. It was at this stage in the vaccine-making process that the misstep occurred.
Chemotherapy for Influenza? When used as a treatment, both neuraminidase inhibitors cut the time to the relief of symptoms -- by about 17 hours for oseltamivir and 14 hours for zanamivir. When used as prophylaxis in people exposed to the flu, both reduced the risk of symptomatic disease but not asymptomatic infection and therefore would have little effect on the risk of transmission during a pandemic. Oseltamivir caused nausea and vomiting and increased the risk of headaches, renal events (decreased creatinine clearance) and psychiatric syndromes (such as confusion and depression). Zanamivir, an inhaled drug, was linked to cases of bronchospasm, but was mostly well tolerated, possibly because it has a low bioavailability. Neither drug was shown to reduce the risk of hospital admission for flu, although there was a slight reduction in self-reported but unverified pneumonia among adults for both drugs. – BMJ 2014;348:g2371; g2524; g2545; g2548 from the Cochrane Reviews
FDA approves Flucelvax by Novartis November 20, 2012 The U.S. Food and Drug Administration announced today the approval of Flucelvax, the first seasonal influenza vaccine licensed in the United States produced using cultured animal cells, instead of fertilized chicken eggs. Flucelvax is approved to prevent seasonal influenza in people ages 18 years and older. The manufacturing process for Flucelvax is similar to the egg- based production method, the virus strains included in the vaccine are grown in animal cells of mammalian origin instead of in eggs. Cell culture technology has already been in use for several decades to produce other U.S. licensed vaccines (polio, rubella and hepatitis A). A subunit influenza virus vaccine prepared from virus propagated in Madin Darby Canine Kidney (MDCK) cells.
Flublok by Protein Sciences Corporation Flublok (Influenza Vaccine) Sterile Solution for Intramuscular Injection contains purified HA proteins produced in a continuous insect cell line (expresSF+®) that is derived from Sf9 cells of the fall armyworm, Spodoptera frugiperda, and grown in serum-free medium composed of chemically-defined lipids, vitamins, amino acids, and mineral salts. Flublok is approved for use in persons 18 through 49 years Flublok has a shorter shelf life, with an expiration period of 16 weeks from the production date, as compared to currently available inactivated influenza vaccines which carry an expiration date of June 30 – For the 2012 - 2013 influenza season it is formulated to contain 135 mcg HA per 0.5 mL dose, with 45 mcg HA of each of the following 3 influenza virus strains: A/California/7/2009 (H1N1), A/Victoria/361/2011 (H3N2), and B/Wisconsin/1/2010. FDA approval 12-21-2012
ACIP Meeting 10-25-2013 Fluzone High-Dose was 24.2% more effective in preventing influenza in 32,000 adults aged 65 years or older than regular Fluzone in a large-scale 2 year clinical trial conducted in the US and Canada, vaccine maker Sanofi Pasteur told the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention today. The rate of laboratory-confirmed influenza among participants receiving Fluzone High-Dose was 1.43% compared with 1.89% among patients immunized with Fluzone. For the FDA to deem Fluzone High-Dose as superior, the vaccine needed to demonstrate a relative efficacy rate of at least 9.1%. It achieved a rate more than twice that RRR=24.2%, ARR = 0.46%, NNT 218
H5N1 Avian Influenza Vaccine Nov 22, 2013 Vaccine to supplement National Stockpile, not intended for commercial availability but it is intended to be made available to the public in a pandemic outbreak. The vaccine, Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted, is for use in people 18 years of age and older who are at increased risk of exposure to the H5N1 avian influenza virus.
H5N1 Avian Influenza Vaccine Most avian influenza A viruses do not infect people. However some viruses, such as H5N1, have caused serious illness and death in people outside of the U.S., mostly among people who have been in close contact with infected and ill poultry. When people do become infected with H5N1, about 60 percent die, according to the World Health Organization.
H5N1 Avian Influenza Vaccine The vaccine is made using an egg-based manufacturing process, which is also used for ID Biomedical Corporations seasonal influenza vaccine, FluLaval. – It contains the adjuvant AS03, an oil-in-water emulsion to enhance the immune response of the vaccinated individual. The adjuvant makes it possible to use a small amount of influenza protein per dose of vaccine to elicit the desired immune response in an individual to prevent influenza disease. Reducing the amount of influenza protein per dose.
H5N1 Avian Influenza Vaccine The H5N1 component and the AS03 adjuvant component are supplied in two separate vials, which must be combined prior to use. The vaccine is administered via intramuscular injection in two doses, 21 days apart. Safety data comes from approximately 3,400 adults 18 years of age and older – Muscle aches, headache, fatigue and injection site pain, redness and swelling were common.
Meningitis type B Meningitis type B is responsible for about a third of U.S. meningitis cases, but is the only strain not currently preventable by an FDA-approved vaccine. In the last year MenB has infected more than a dozen students at Princeton, UC-Santa Barbara, and Drexel. MenB is a potentially deadly disease which is easily misdiagnosed and can kill within 24 hours of onset. About one in 10 of those who contract the disease will die despite appropriate treatment. Up to one in five survivors may suffer from devastating, life-long disabilities such as brain damage, hearing impairment or limb loss.
Meningitis type B Vaccine Bexsero®, a multi-component Meningococcal B (MenB) vaccine (recombinant, adsorbed) suspension for injection 0.5 ml pre-filled syringe by Novartis is under review at the FDA Safety and efficacy have been shown through clinical trials involving more than 8,000 people including infants, children, adolescents and adults. Available in Canada, EU and Australia NOT YET FDA Approved
Acetaminophen Update January 13, 2011 FDA Drug Safety Communication: Prescription Acetaminophen Products to be Limited to 325 mg Per Dosage Unit - The FDA is asking drug manufacturers to limit the strength of acetaminophen in prescription drug products, which are predominantly combinations of acetaminophen and opioids. This action will limit the amount of acetaminophen in these products to 325 mg per tablet, capsule, or other dosage unit, making these products safer for patients. Drug companies will have three years from the date of publication of the Federal Register Notice (January 14, 2011) to limit the amount of acetaminophen in their oral prescription drug products to 325 mg per dosage unit (see the Federal Register Notice2 Docket number FDA-2011- N-0021-0001). In addition, a Boxed Warning highlighting the potential for severe liver injury and a Warning highlighting the potential for allergic reactions (e.g., swelling of the face, mouth, and throat, difficulty breathing, itching, or rash) are being added to the label of all prescription drug products that contain acetaminophen.
FDA recommends against prescribing and dispensing prescription combination drug products with more than 325 mg of acetaminophen More than half of manufacturers have voluntarily complied with our request. However, some prescription combination drug products containing more than 325 mg of acetaminophen per dosage unit remain available. In the near future we intend to institute proceedings to withdraw approval of prescription combination drug products containing more than 325 mg of acetaminophen per dosage unit that remain on the market. – FDA Jan 14, 2014

DEA Notice of Proposed Rule Making Feb 27, 2014 The Drug Enforcement Administration (DEA) proposes to reschedule hydrocodone combination products from schedule III to schedule II of the Controlled Substances Act. This proposed action is based on a rescheduling recommendation from the Assistant Secretary for Health of the Department of Health and Human Services and an evaluation of all other relevant data by the DEA. If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule II controlled substances. The DEA will receive comments until April 28, 2014
FDA Approves Zohydro ER C-II 10/26/2013 The U.S. Food and Drug Administration today approved Zohydro ER (hydrocodone bitartrate extended-release capsules) by Zogenix for the management of pain severe enough to require daily, around-the-clock, long-term treatment and for which alternative treatment options are inadequate. – The first FDA-approved single-entity (not combined with an analgesic such as acetaminophen) and extended-release hydrocodone product.
Hydrocodone bitartrate extended- release capsules – Zohydro ER ER/LA opioid formulations like Zohydro ER should be reserved for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. Zohydro ER is not approved for as-needed pain relief. – The approved labeling for Zohydro ER conforms to updated labeling requirements for all ER/LA opioid analgesics announced by the FDA on Sept. 10, 2013.
Hydrocodone bitartrate extended- release capsules – Zohydro ER Extended-release capsules: 10 mg, 15 mg, 20 mg, 30 mg, 40 mg and 50 mg – Capsules must be swallowed whole and are not to be chewed, crushed or dissolved. For opioid-naïve and opioid non-tolerant patients, initiate with 10 mg capsules orally every 12 h. To convert to Zohydro ER from another opioid, use available conversion factors to obtain estimated dose. Increase the dose of Zohydro ER in increments of 10 mg every 12 hours every 3 to 7 days as needed to achieve adequate analgesia.
EVZIO (Naloxone) Auto-Injector FDA approved 4-3-2014 by Kaleo (1-P review) Indication: Naloxone is an opioid antagonist indicated for the emergency treatment of known or suspected opioid overdose, as manifested by respiratory and/or central nervous system depression. (primarily intended for use by the care-giver or a family member) Each dose is 0.4mg of naloxone/0.4 ml – Only comes in boxes of two single dose auto-injectors plus a training auto-injector that may be reused
EVZIO (Naloxone) Auto-Injector A video which demonstrates how to use the auto- injector is available at www.EVZIO.com
EVZIO (Naloxone) Auto-Injector Dosage and Administration: EVZIO is for intramuscular or subcutaneous use only. Administer EVZIO to adult or pediatric patients into the anterolateral aspect of the thigh, through clothing if necessary. – Additional doses may be administered every 2 to 3 minutes until emergency medical assistance arrives. In pediatric patients under the age of one, the caregiver should pinch the thigh muscle while administering the dose Seek emergency medical care immediately after use.
EVZIO (Naloxone) Auto-Injector Naloxone is fast onset with peak levels in about 15 min and a half-life of ~1.5 hours (~3.0 hours in neonates) Naloxone will produce rapid reversal of the respiratory and CNS effects of opioids but may only last for 2-3 hours – Reversal of partial agonist/antagonists like buprenorphone and pentazocine maybe slow and incomplete especially with buprenorphone and may require larger repeat doses
EVZIO (Naloxone) Auto-Injector Patients on long-term opioids will experience opioid withdrawal with nausea, vomiting, sweating, increased heart rate, increased blood pressure, tremors, weakness, body aches and potential seizures as well as increased risk of cardiac events. In neonates, opioid withdrawal may be life- threatening if not recognized and properly treated
FDA Drug Safety Communication - Olmesartan 7-3-2013 FDA approves label changes to include intestinal problems (sprue-like enteropathy) linked to blood pressure medicine olmesartan medoxomil (Benicar, Azor, Tribenzor) – Symptoms of sprue-like enteropathy include severe, chronic diarrhea with substantial weight loss. The enteropathy may develop months to years after starting olmesartan, and sometimes requires hospitalization. – Discontinuation of olmesartan has resulted in clinical improvement of sprue-like enteropathy symptoms in all patients. In June 2012, Mayo Clinic researchers published a case series of sprue-like enteropathy associated with olmesartan in 22 patients (Mayo Clin Proc 2012;87:732-8)
ACE Inhibitors vs. ARBs on Outcomes in Patients with Diabetes Twenty-three trials compared ACEIs with placebo or active drugs (32827 patients) and 13 compared ARBs with no therapy (controls) (23867 patients). When compared with controls (placebo/active treatment), ACEIs significantly reduced the risk of all-cause mortality by 13% (RR, 0.87; 95% CI, 0.78-0.98), CV deaths by 17% (0.83; 0.70-0.99), and major CV events by 14% (0.86; 0.77-0.95), including myocardial infarction by 21% (0.79; 0.65-0.95) and heart failure by 19% (0.81; 0.71-0.93). – JAMA Intern Med. doi:10.1001/jamainternmed.2014.348 Published online March 31, 2014.
ACE Inhibitors vs. ARBs on Outcomes in Patients with Diabetes Treatment with ARBs did not significantly affect all-cause mortality (RR, 0.94; 95% CI, 0.82-1.08), CV death rate (1.21; 0.81-1.80), and major CV events (0.94; 0.85-1.01) with the exception of heart failure (0.70; 0.59-0.82). Both ACEIs and ARBs were not associated with a decrease in the risk for stroke in patients with DM. Meta-regression analysis showed that the ACEI treatment effect on all-cause mortality and CV death did not vary significantly with the starting baseline blood pressure and proteinuria of the trial participants and the type of ACEI and DM. Conclusion: ACEIs should be considered as first-line therapy to limit excess mortality and morbidity in this population. – JAMA Intern Med. doi:10.1001/jamainternmed.2014.348 Published online March 31, 2014.
FDA Drug Safety Update 8/15/2013 Flouroquinolones may cause disabling peripheral neuropathy symptoms in the arms or legs such as pain, burning, tingling, numbness, weakness, or a change in sensation to light touch, pain or temperature. These symptoms can occur early in treatment and may be permanent. It can occur at any time during treatment with fluoroquinolones and can last for months to years after the drug is stopped or be permanent. Patients using fluoroquinolones who develop any symptoms of peripheral neuropathy should tell their health care professionals right away.
Digoxin in Heart Failure : ACC/AHA Heart Failure Guidelines 2013 Class IIa Digoxin can be beneficial in patients with HFrEF, unless contraindicated, to decrease hospitalizations for HF. (Level of Evidence: B) – Digoxin Intervention Group Trial (N Engl J Med 1997;336:525-33) – Doses of digoxin that achieve a plasma concentration of drug in the range of 0.5 to 0.9 ng/mL are suggested, given the limited evidence currently available Circulation. published online June 5, 2013
Digoxin and Outcomes? New digoxin use and risks of death and HF hospitalization, controlling for medical history, laboratory results, medications, HF disease severity, and the propensity for digoxin use. We also conducted analyses stratified by sex and concurrent β- blocker use. Among 2891 newly diagnosed patients with systolic HF, 529 (18%) received digoxin. During a median 2.5 years of follow-up, incident digoxin use was associated with higher rates of death (14.2 versus 11.3 per 100 person-years) and HF hospitalization (28.2 versus 24.4 per 100 person-years). In multivariable analysis, incident digoxin use was associated with higher mortality (hazard ratio, 1.72; 95% confidence interval, 1.25–2.36) but no significant difference in the risk of HF hospitalization (hazard ratio, 1.05; 95% confidence interval, 0.82–1.34). –Results were similar in analyses stratified by sex and β-blocker use. Circ Cardiovasc Qual Outcomes. 2013;6:525-533
Digoxin after 230 years? The Editorial by Dr. Opie entitled Digitalis, Yesterday and Today, But Not Forever concludes: This conclusion is the opposite of what the earlier studies favoring digoxin use in the bygone era of imperfect therapy for HF had found, with the new conclusion that therapy for HF that includes β-blockade and full angiotensin-II modulation dispenses with the need for taking the risks of adding digoxin therapy. The data at our disposal, taking into account the current study, allow us to seriously question the advice on digoxin given by both the current and influential guidelines, European and Americ an. – Circ Cardiovasc Qual Outcomes. 2013;6:511-513
Aspirin in Patients with Heart Failure A retrospective cohort study of 1476 patients (mean age 70.4±12.4 years, 63% male) attending a HF disease management program examined aspirin use at baseline and its association with mortality and HF hospitalization. 892 (60.4%) were prescribed aspirin (75mg/day in 92.8%). Median follow-up time was 2.6 [0.8:4.5] years. – Over the follow-up period, 464 (31.4%) patients died. In adjusted analysis, low-dose aspirin use was associated with reduced mortality risk compared to non-aspirin use (HR=0.58, 95% CI 0.46–0.74). – Low-dose aspirin use was associated with reduced risk of HF hospitalization compared to non-aspirin use in the total population (adjusted HR=0.70, 95% CI 0.54–0.90). 10.1161/CIRCHEARTFAILURE.113.000132 (on-line 2-5-2014)
Aspirin in Patients with Heart Failure In adjusted analysis, there was no difference in mortality or HF hospitalization between high-dose aspirin users (>75mg/day) and non- aspirin users. Conclusions In this study low-dose aspirin therapy was associated with a significant reduction in mortality and morbidity risk over long-term follow-up. – 10.1161/CIRCHEARTFAILURE.113.000132 (on-line 2-5-2014)
OTC Nasacort Allergy 24hr Nasal Spray Sanofi/Chattem announced that Nasacort (triamcinolone acetonide) Allergy 24hr Nasal Spray is now available over-the-counter (OTC) to relieve a range of seasonal and year-round nasal allergy symptoms, including nasal congestion, in adults and children >2 years of age. – Nasacort spray in 60 (~$12) and 120 (~$18) metered dose sprays. (55mcg/spray which is the same as the prescription (vs ~$58.00 for the generic Rx) – Nasacort was approved for the switch from prescription to OTC by the FDA on October 11, 2013.
FDA Approves OTC Nexium 24 HR by Pfizer March 28, 2014 The FDA approved Nexium 24 HR (esomeprazole magnesium 22.3 mg equivalent to esomeprazole base 20 mg ) for the treatment of frequent heartburn after Pfizer acquired the rights to market the OTC version from Astra Zeneca for $250 million and royalties based upon sales. Nexium 24 HR joins Prilosec OTC, Prevacid 24 HR and Zegerid OTC all QD for 14 days for treatment of frequent heartburn
NSAIDs and Atrial Fibrillation? Data from the population-based follow-up study, the Rotterdam Study comprised of 8423 participants without atrial fibrillation at baseline (the mean age of the study population was 68.5years (SD: 8.7) and 58% were women). During a mean follow-up of 12.9years, 857 participants developed atrial fibrillation. Current use of NSAIDs was associated with increased risk compared with never-use (HR 1.76, 95% CI 1.07 to 2.88). Also, recent use (within 30days after discontinuation of NSAIDs) was associated with an increased risk of atrial fibrillation compared with never-use (HR 1.84, 95% CI 1.34 to 2.51) adjusted for age, sex and several potential confounders. – BMJOpen 2014; 4: e004059. doi:10.1136/
FDA Drug Safety Communication- Testosterone Products Jan 31,2014 The FDA is investigating the risk of stroke, heart attack, and death in men taking FDA-approved testosterone products. – Testosterone products are FDA-approved only for use in men who lack or have low testosterone levels (<300ng/dl) in conjunction with an associated medical condition. Examples include failure of the testicles to produce testosterone, because of reasons such as genetic problems or chemotherapy. Other examples include problems with the hypothalamus and pituitary that control the production of testosterone by the testicles. – None of the FDA-approved testosterone products are approved for use in men with low testosterone levels who lack an associated medical condition. FDA-approved testosterone formulations include the topical gel, transdermal patch, buccal system (applied to upper gum or inner cheek), and injection.
FDA Drug Safety Communication- Testosterone Products An observational study of older men in the U.S. Veteran Affairs health system – The population was a very specific group of men who had coronary heart disease based upon coronary angiography and had their testosterone levels measured (<300 ng/dL) before they had a myocardial infarction, rather than after. These men received an appropriate prescription and filled it at least once to see what would happen. The investigators ended up with approximately 8700 men, about 1275 of whom had been given testosterone, and they examined the outcomes. – They looked at all-cause mortality, strokes, and heart attacks. They found that giving testosterone at recommended levels to men who were candidates for it actually raised their testosterone levels, as might be expected. JAMA. 2013;310:1829-1836
FDA Drug Safety Communication- Testosterone Products The absolute rate of events (all-cause mortality, MI, and ischemic stroke) were 19.9% in the no testosterone therapy group vs 25.7% in the testosterone therapy group, with an absolute risk difference of 5.8% (95% CI, -1.4% to 13.1%) (NNH = 18) at 3 years after coronary angiography. In Cox proportional hazards models adjusting for the presence of coronary artery disease, testosterone therapy use as a time-varying covariate was associated with increased risk of adverse outcomes (hazard ratio, 1.29; 95% CI, 1.04 to 1.58). – JAMA. 2013;310:1829-1836
FDA Drug Safety Communication- Testosterone Products A cohort study of the risk of acute non-fatal myocardial infarction (MI) following an initial topical testosterone (TT) prescription (N = 55,593) in a large US health-care database. – Compared the incidence rate of MI in the 90 days following the initial prescription (post-prescription interval) with the rate in the one year prior to the initial prescription (pre-prescription interval) (post/pre). – Also compared post/pre rates in a cohort of men prescribed phosphodiesterase type 5 inhibitors (PDE5I; sildenafil or tadalafil, N = 167,279), and compared TT prescription post/pre rates with the PDE5I post/pre rates,adjusting for potential confounders PLOS ONE www.plosone.org January 2014 Volume 9 Issue 1 85805
FDA Drug Safety Communication- Testosterone Products Results: In all subjects, the post/pre-prescription rate ratio (RR) for TT prescription was 1.36 (1.03, 1.81). In men aged 65 years and older, the RR was 2.19 (1.27, 3.77) for TT prescription and 1.15 (0.83, 1.59) for PDE5I, and the ratio of the rate ratios (RRR) for TT prescription relative to PDE5I was 1.90 (1.04, 3.49). The RR for TT prescription increased with age from 0.95 (0.54, 1.67) for men under age 55 years to 3.43 (1.54, 7.56) for those aged >75 years (ptrend = 0.03), while no trend was seen for PDE5I (ptrend = 0.18). In men under age 65 years, excess risk was confined to those with a prior history of heart disease, with RRs of 2.90 (1.49, 5.62) for TT prescription and 1.40 (0.91, 2.14) for PDE5I, and a RRR of 2.07 (1.05, 4.11). – PLOS ONE www.plosone.org January 2014 Volume 9 Issue 1 85805
FDA Drug Safety Communication- Testosterone Products At this time, FDA has not concluded that FDA- approved testosterone treatment increases the risk of stroke, heart attack, or death. Patients should not stop taking prescribed testosterone products without first discussing any questions or concerns with their health care professionals. Health care professionals should consider whether the benefits of FDA-approved testosterone treatment is likely to exceed the potential risks of treatment. The prescribing information in the drug labels of FDA-approved testosterone products should be followed.
FDA Approves Testosterone Undecanoate Injection March 6, 2014 the FDA approved Aveed (testosterone undecanoate) injection for the treatment of adult men with hypogonadism (commonly known as Low-T) that is associated with a deficiency or absence of the male hormone testosterone. Aveed is a new prescription medicine indicated to produce serum testosterone levels in the normal range by administration of a single 3-mL (750 mg) intramuscular injection given once at initiation of therapy, at 4 weeks, and then every 10 weeks thereafter.
Testosterone Undecanoate Injection - Aveed Approval of Aveed is based on data from an 84- week Phase 3 trial of hypogonadal men in the U.S. Men enrolled in the study had an average age of 54 years and a serum total testosterone level of less than 300 ng/dL. In the Phase 3 study, Aveed increased mean serum testosterone levels, maintaining them for up to 10 weeks at steady state (between weeks 14-24). Aveed is approved with a Risk Evaluation and Mitigation System (REMS) requiring prescriber education and certification as well as restricted product distribution.
Testosterone Undecanoate Injection - Aveed Indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone, including primary hypogonadism (congenital or acquired) and hypogonadotropic hypogonadism (congenital or acquired). Aveed has a Boxed Warning for serious pulmonary oil microembolism (POME) reactions and anaphylaxis. It should be used in patients who require therapy and in whom the benefits of the product outweigh the serious risks of POME and severe allergic reaction (anaphylaxis). It must be prescribed and administered by trained healthcare providers in a doctor's office, clinic, or hospital. – Patients must remain in the administering physician's office or clinic for at least 30 minutes after injection so that short- term reactions may be observed and treated.
Testosterone Undecanoate Injection - Aveed Other potential adverse effects include worsened prostate enlargement, liver toxicity, peripheral edema, sleep apnea, and venous thrombosis. Shortly after Endo announced the approval, the consumer group Public Citizen called on the FDA to reverse it, citing recent studies that suggest increased cardiovascular risk with testosterone products.

Whats New 2013 ACC/AHA Guideline on the Treatment of Blood Cholesterol Global Risk Assessment for Primary Prevention This guideline recommends use of the new Pooled Cohort Equations to estimate 10-year ASCVD risk in both white and black men and women. (Controversial?) – By more accurately identifying higher risk individuals for statin therapy, the guideline focuses statin therapy on those most likely to benefit. – It also indicates, based on RCT data, those high-risk groups that may not benefit. – Before initiating statin therapy, this guideline recommends a discussion by clinician and patients.

AHA/ACC Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults. The new guidelines have also drawn considerable criticism especially when it comes to primary prevention and the new recommendation for a 10 year CV risk level of 7.5% with the new risk calculator. Ridker and Cook in a Lancet Editorial commend the new guideline for its emphasis on improving and simplifying use of statins. However, they calculate that the risk prediction algorithm used in the guideline has systematically overestimated cardiovascular risks, and could therefore lead to overtreatment. – Lancet November 23. 2013 pp 1680

AHA/ACC Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults. Treating to LDL cholesterol targets is no longer recommended; rather, clinicians should determine whether a patient falls into one of four mutually exclusive high-risk groups and should initiate statin therapy as follows: 1. Patients with clinical atherosclerotic cardiovascular disease (ASCVD) should receive high-intensity (age, <75) or moderate-intensity (age, 75) statin therapy 2. Patients with LDL cholesterol levels 190 mg/dL should receive high-intensity statin therapy. J Am Coll Cardiol 2013 Nov 12; [e-pub ahead of print]
AHA/ACC Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults. 3. Patients with diabetes aged 40–75 with LDL cholesterol levels of 70–189 mg/dL and without clinical ASCVD should receive at least moderate- intensity statin therapy (and possibly high-intensity statin therapy when estimated 10-year ASCVD risk is 7.5%) 4. Patients without clinical ASCVD or diabetes but with LDL cholesterol levels of 70–189 mg/dL and estimated 10-year ASCVD risk 7.5% should receive moderate- or high-intensity statin therapy J Am Coll Cardiol 2013 Nov 12; [e-pub ahead of print]
AHA/ACC Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults. High-intensity statin therapies are atorvastatin (40–80 mg) or rosuvastatin (Crestor; 20–40 mg). Moderate-intensity statin therapies include atorvastatin (10–20 mg), rosuvastatin (5–10 mg), simvastatin (20–40 mg), pravastatin (40–80 mg), and several others With few exceptions, use of lipid-modifying drugs other than statins is discouraged. Lifestyle modification is recommended for all patients, regardless of cholesterol-lowering drug therapy – J Am Coll Cardiol 2013 Nov 12; [e-pub ahead of print]
High Potency Statins vs. Simvastatin vs. Simvastatin plus Ezetimibe? The UK General Practice Research Database reviewed 9597 patients (57% male, mean age of 65 ±13 years) matched study criteria (had survived 30 days after their rst acute myocardial infarct (AMI), had not received prior statin or ezetimibe therapy and were started on a statin within 30 days of AMI were included). Primary outcome was all cause mortality Simvastatin (n=6990 (72.8%)); high-potency statin (n=1883, (19.6%)); and ezetimibe/statin combination (n=724 (7.5%)). During a mean follow-up of 3.2 years, there were 1134 (12%) deaths. – the study lacked statistical power to determine any mortality effect with ezetimibe.

AHA/ACC Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults. This guideline represents a paradigm shift for most clinicians and patients. The rationale for abandoning LDL cholesterol targets is that randomized trials showing benefits of statins generally have examined fixed-dose statin therapy, rather than titrated therapy, to achieve prespecified LDL cholesterol goals. Additionally, some drugs that improve the lipid profile (a surrogate endpoint) do not improve clinical outcomes, and statins are thought to exert benefit through pleiotropic effects apart from LDL cholesterol–lowering. – J Am Coll Cardiol 2013 Nov 12; [e-pub ahead of print]
Statins and Erectile Function? Data presented at the 2014 ACC Meeting in Wash DC The investigators searched for randomized controlled trials that examined the effect of statin therapy on erectile function. They identified 11 such trials in which men completed the International Inventory of Erectile Function survey, which consists of five questions, each scored on a five-point scale, where low values represent poor sexual function – a total of 647 men, an average age of 57.8 years and who had received statins for about 3.8 months. – average LDL-C levels dropped significantly from 138 to 91 mg/dL in the treated men but were virtually unchanged in control groups. Journal of Sexual Medicine first published online: 29 MAR 2014 DOI: 10.1111/jsm.12521
Statins and Erectile Function? Men who took statins had their erectile-function scores increased by 3.4 points, from 14.0 to 17.4 pointsa 24.3% increase. The increase in erectile-function score was about one-third to one-half of that reported with phosphodiesterase inhibitors (PDE-5 inh). – Pluses and Minuses: they improve endothelial function, which may improve blood flow to the penis; but on the other hand, they lower the level of cholesterol, a precursor of testosterone.

Hepatitis C An estimated 3 million to 4 million persons in the United States are chronically infected with HCV, and approximately half are unaware of their status. – These individuals may ultimately progress to advanced liver disease and/or hepatocellular cancer. However, those outcomes can be prevented by treatment, which is rapidly improving and offers the potential of a cure to more patients than has been previously possible. – HCV testing is recommended at least once for persons born between 1945 and 1965.
Hepatitis C Risk behaviors: Injection-drug use (current or ever, including those who injected once) Intranasal illicit drug use Risk exposures Long-term hemodialysis (ever) Getting a tattoo in an unregulated setting Healthcare, emergency medical, and public safety workers after needle sticks, sharps, or mucosal exposures to HCV-infected blood Children born to HCV-infected women Prior recipients of transfusions or organ transplants, including persons who: were notified that they received blood from a donor who later tested positive for HCV infection, received a transfusion of blood or blood components, or underwent an organ transplant before July 1992, received clotting factor concentrates produced before 1987 Were ever incarcerated
FDA Approval of Jansens Simeprevir - Olysio Oct 24, 2013 The FDA Antiviral Drugs Advisory Committee voted unanimously (19 to 0) to recommend approval of the investigational protease inhibitor simeprevir (TMC435) administered once daily as a 150 mg capsule with pegylated interferon and ribavirin for the treatment of genotype 1 chronic hepatitis C in adult patients with compensated liver disease, including cirrhosis. The Advisory Committee recommended the approval of simeprevir based on analyses of data from clinical trials in patients who are treatment-naive (QUEST-1 and QUEST-2)or who have failed previous interferon-based therapy (PROMISE). FDA Approved 11-22-2013 Cost: $21,221.93/28 X 150 mg caps WAC
Simeprevir - Olysio Clinical trials found simeprevir can reduce treatment time in half to 24 weeks. The medicine cured about 80 percent of patients who hadnt been treated before compared with 50 percent of those who took pegylated interferon and ribavirin. Seventy-nine percent of simeprevir users who failed other treatments were cured compared with 37 percent who took only the older drugs,
Simeprevir - Olysio For patients infected with genotype 1a HCV, baseline resistance testing for the Q80K polymorphism may be considered. However, in contrast to using simeprevir to treat a genotype 1a HCV patient with PEG/RBV when the mutation markedly alters the probability of an SVR, the finding of the Q80K polymorphism does not preclude treatment with simeprevir and sofosbuvir, because the SVR rate was high in patients with genotype 1a/Q80K infection (SVR12 rate for cohort 1 was 86% [24 of 28 patients]. Thus Q80K testing can be considered but is not strongly recommended. – http://www.hcvguidelines.org 2014 accessed 2-3-2014
Adverse Events with Simeprevir
Simeprevir - Olysio The most common major side effects of simeprevir were rash and photosensitivity. Panel members agreed with the FDA that the prescribing information for the drug should include a recommendation for patients to use sun protection and avoid tanning beds.
Simeprevir - Olysio Sulfa Allergy? Simeprevir contains a sulfonamide moiety. In subjects with a history of sulfa allergy (n=16), no increased incidence of rash or photosensitivity reactions has been observed. However, there are insufficient data to exclude an association between sulfa allergy and the frequency or severity of adverse reactions observed with the use of Simeprevir.
FDA Approval of Gileads Sofosbuvir - Sovaldi The FDA Advisory Comm. unanimously recommended approval on Oct 25,2013, the FDA approved it on Dec 6, 2013 as a Breakthrough medication. Cost $26,863.20/28 x 400 mg tabs WAC – The FDA didnt find any heart risks associated with sofosbuvir after Bristol-Myers and Idenix Pharmaceuticals Inc. discontinued development of drugs in the same class last year based on cardiovascular safety concerns.
Sofosbuvir -Sovaldi A hepatitis C virus (HCV) nucleotide analog NS5B polymerase inhibitor indicated for the treatment of chronic hepatitis C (CHC) infection as a component of a combination antiviral treatment regimen. Efficacy has been established in subjects with HCV genotype 1, 2, 3 or 4 infection, including those with hepatocellular carcinoma meeting Milan criteria (awaiting liver transplantation) and those with HCV/HIV-1 co-infection
Sofosbuvir -Sovaldi Dosage: One 400 mg tablet taken once daily with or without food Drug Interactions: Drugs that are potent P-gp inducers in the intestine (e.g., rifampin, St. Johns wort) may significantly decrease sofosbuvir plasma concentrations and may lead to a reduced therapeutic effect
Sofosbuvir - Sovaldi Safety – No serious or severe cardiac adverse events occurred in sofosbuvir-treated patients, and no treatment discontinuations occurred due to cardiac adverse events. Palpitations were the only Grade 2 event found in the SOF + RBV group. Eleven patients in the SOF + RBV group experienced Grade 1 events including palpitations, tachycardia, sinus bradycardia, extrasystoles, and ventricular extrasystoles.

Cost vs. Benefit? A panel of experts at a recent forum in San Francisco concluded that the drug offered low value for treating most patients, in large part because of its high price. That judgment was based partly on an assessment of clinical and cost-effectiveness prepared by a nonprofit organization that evaluates medical treatments (the Boston-based Institute for Clinical and Economic Review). The group estimated that replacing current care of infected Californians with Sovaldi-based regimens would raise drug expenditures in the state by $18 billion or more in a single year. It said projected savings from reduced medical costs in later years would not come close to offsetting that cost. – New York Times March 15, 2014
Cost vs. Benefit? The drug will be sold for much less in many other countries. Gilead plans to license three to five Indian drug makers to produce Sovaldi and expects the price to be perhaps $2,000 for six months of treatment through public hospitals and community clinics in India (compared with $168,000 for six months in the United States). Gilead said similar arrangements might be made in 60 low- and middle-income countries. Prices in Europe are high, but not as high as in the United States. – New York Times March 15, 2014
Cost vs. Benefit? What can or should be done to reduce the cost in the United States? Some experts suggest providing the drug only to patients with advanced liver disease. Others hope that other new drugs in late stages of clinical testing will be approved, adding competition that could help restrain prices. Still others urge that state Medicaid agencies, which cover a big portion of the infected people, negotiate with Gilead for lower prices or find ways to limit the drugs use when other good options are available. There is no easy way to contain costs as expensive new drugs come along, so all of these strategies will need to be tried. – New York Times March 15. 2014
Am Acad Neurology Evidence-based guideline update: Prevention of stroke in nonvalvular atrial fibrillation These guidelines have been endorsed by the World Stroke Organization For patients with NVAF, which therapies that include antithrombotic medication, as compared with no therapy or with another therapy, reduce stroke risk and severity with the least risk of hemorrhage? – In patients who have NVAF but no risk factors, the absolute risk of major bleeding (3%/year) is larger than the absolute reduction in stroke from anticoagulation (1.3%/year).

Am Acad Neurology Evidence-based guideline update: Prevention of stroke in nonvalvular atrial fibrillation Selection of a Specific Oral Anticoagulant To reduce the risk of stroke or subsequent stroke in patients with NVAF judged to require oral anticoagulants, clinicians should choose one of the following options: Warfarin, target international normalized ratio (INR) 2.0–3.0 Dabigatran 150 mg twice daily (if creatinine clearance [CrCl] > 30 mL/min) Rivaroxaban 15 mg/day (if CrCl 30–49 mL/min) or 20 mg/day Apixaban 5 mg twice daily (if serum creatinine 1.5 and < 2.5 mg/dL, and body weight < 60 kg or age at least 80 years [or both]) Level B Neurology® 2014;82:716–724
Am Acad Neurology Evidence-based guideline update: Prevention of stroke in nonvalvular atrial fibrillation GI bleeding risk Clinicians might offer apixaban to patients with NVAF and GI bleeding risk who require anticoagulant medication.

Am Acad Neurology Evidence-based guideline update: Prevention of stroke in nonvalvular atrial fibrillation Patients unsuitable for warfarin Clinicians should offer apixaban to patients unsuitable for being treated, or unwilling to be treated, with warfarin. Level B Where apixaban is unavailable, clinicians might offer dabigatran or rivaroxaban. Level C Where oral anticoagulants are unavailable, clinicians might offer a combination of aspirin and clopidogrel. Level C Neurology® 2014;82:716–724
Am Acad Neurology Evidence-based guideline update: Prevention of stroke in nonvalvular atrial fibrillation Special populations Clinicians should routinely offer oral anticoagulants to elderly patients (aged > 75 years) with NVAF if there is no history of recent unprovoked bleeding or intracranial hemorrhage. Clinicians might offer oral anticoagulation to patients with NVAF who have dementia or occasional falls. However, clinicians should counsel patients or their families that the risk–benefit ratio of oral anticoagulants is uncertain in patients with NVAF who have moderate to severe dementia or very frequent falls.

2014 AHA/ACC/HRS Atrial Fibrillation Guideline Little benefit with aspirin: This quote says a lot. "No studies, with the exception of the [Stroke Prevention in Atrial Fibrillation-1] SPAF-1 trial, show benefit for aspirin alone in preventing stroke among patients with AF. – urged to question the common practice of using aspirin in low-risk patients. "aspirin has not been studied in a low- risk AF population" AF ablation has been moved to first-line status for both paroxysmal and persistent AF patients. This welcome change aligns these guidelines with those from Europe – AF ablation should not be performed in patients who cannot be treated with anticoagulants, and AF ablation should not be done with the sole intent of avoiding anticoagulation.

COPD Treatment and CV Events? A nested case-control analysis of a retrospective cohort study in Ontario compared the risk of events between older COPD patients newly prescribed inhaled long acting beta-agonists (LABA) and long acting anticholinergics (LAMA), after matching and adjusting for prognostic factors Main Outcome and Measures: An emergency department visit or a hospitalization for a cardiovascular event. – JAMA Intern Med. Published online May 20, 2013
COPD Treatment and CV Events? Results: Of 191 005 eligible patients, 53 532 (28.0%) had a hospitalization or an emergency department visit for a cardiovascular event. Patients newly prescribed a LABA and/or a LAMA were found to have a greater risk of an event compared with nonuse of those medications (respective adjusted odds ratios, 1.31 [95% CI, 1.12- 1.52; P<.001] and 1.14 [1.01-1.28; P=.03]). – No significant difference in events between the 2 medications (adjusted odds ratio of long-acting inhaled beta-agonists compared with anticholinergics, 1.15 [95% CI,0.95-1.38; P=.16]).

COPD Treatment and CV Events? "These results along with the previous data support the need for close monitoring of all patients with COPD who require long-acting bronchodilators, regardless of drug class," study author Gershon and colleagues state. That conclusion, however, sits ill with Woodruff who points out in the accompanying Editorial that without a firm recommendation as to what exactly this monitoring should consist of, monitoring remains the same as it has always beenthe responsibility of the treating physician. – HeartWire Clinical Cardiology May 20, 2013
Vortioxetine - Brintellix by Takeda A Selective Serotonin Reuptake Inhibitor (SSRI) antidepressant approved for treatment of major depressive disorder (MDD). – a 5-hydroxytryptamine 1A (5-HT1A) agonist, 5- HT1B partial agonist, 5-HT3 antagonist, 5-HT7 antagonist, and 5-HT transporter protein inhibitor – net effect of these activities is an increase in the levels of 5-HT, noradrenaline, dopamine, and acetylcholine, and histamine in the ventral hippocampus and medial prefrontal cortex
Vortioxetine - Brintellix The half-life of vortioxetine is approximately 66 hours because of the large apparent volume of distribution About 98% bound to plasma proteins Metabolized mainly by cytochrome P450 (CYP 2D6) with 6 total metabolites with little to no antidepressant activity – Vortioxetine and its primary metabolite have been shown to be substrates and weak inhibitors of CYP2C19, but coadministration studies have not shown clinical significance in humans. Vortioxetine has minimal renal clearance, and negligible amounts of the drug found in urine
Vortioxetine - Brintellix The labeling for vortioxetine contains the boxed warning regarding suicidal thoughts and behaviors that is required for all antidepressants. Use of antidepressants in the treatment of children, adolescents, and young adults was associated with increases in the risk of suicidal thoughts and behaviors and a trend towards reduced risk in patients 65 years and older. All patients will need to be monitored for changes in mental function, behavior, and suicidal ideation. Use of antidepressants may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder. Activation of mania/hypomania may occur in patients with major affective disorder.

Vortioxetine - Brintellix Drug Interactions: The risk of serotonin syndrome is increased when vortioxetine is used with other drugs that affect the serotonergic neurotransmitter system (eg, SSRIs, SNRIs, triptans, buspirone, tramadol, tryptophan) – Serotonn syndrome symptoms may include changes in mental status (eg, agitation, hallucinations, delirium, coma), autonomic instability (eg, tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (eg, tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or GI symptoms (eg, nausea, vomiting, diarrhea).
Vortioxetine - Brintellix Drug Interactions: Bupropion: The active metabolites of bupropion inhibit CYP2D6, the primary metabolizing agent of vortioxetine. Multiple doses of bupropion 150 mg twice daily coadministered with vortioxetine 10 mg once daily increased the steady-state plasma exposure of vortioxetine 2-fold. Reduction in vortioxetine dose by 50% or avoidance of bupropion therapy may be necessary NSAIDs: vortioxetine and NSAID,s may both inhibit platelets and increase the risk of bleeding Warfarin: vortioxetine is a weak inhibitor of CYP2C9 in vitro, which is known to metabolize warfarin. However, multiple daily doses of vortioxetine 10 mg had no effect on the steady- state pharmacokinetics or pharmacodynamics of warfarin
Vortioxetine - Brintellix Dosage: The recommended starting dose is 10 mg administered orally once daily without regard to meals. Dosage should then be increased to 20 mg/day, as tolerated, because higher doses demonstrated better treatment effects in trials conducted in the United States. The efficacy and safety of doses above 20 mg/day have not been evaluated in controlled clinical trials. A dose decrease down to 5 mg/day may be considered for patients who do not tolerate higher doses The maximum recommended dosage for known CYP2D6 poor metabolizers is 10 mg/day Vortioxetine is available as 5, 10, 15, and 20 mg immediate-release tablets Cost: $209.25 for 30 tabs WAC
Vortioxetine - Brintellix Abrupt discontinuation of antidepressant therapy can produce discontinuation symptoms (eg, headache, muscle tension, mood swings, sudden outbursts of anger, dizziness, runny nose) during the next week. Some patients experienced these types of symptoms after abrupt discontinuation of vortioxetine 15 and 20 mg/day
Vortioxetine - Brintellix CONCLUSION: Vortioxetine has a mechanism of action that is different from other antidepressant medications. The results from the evaluated clinical studies are mixed. Some studies show no benefit compared with placebo, while others did show a benefit. Several of the studies have used duloxetine as an active comparator, but were not designed to compare the efficacy of vortioxetine with duloxetine. Vortioxetine appears to be well tolerated. Its place in the treatment of patients with MDD, who are treatment-naive and non–treatment naive, remains to be documented.
Levomilnacipran -Fetzima by Forest A Serotonin and Norepinephrine Reuptake Inhibitor (SNRI) both levomilncaipran and milnacipran bind to both serotonin and norepinephrine transporters with high affinity, but milnacipran preferentially blocks norepinephrine reuptake compared with serotonin reuptake by an approximately 3 to 1 ratio, while levomilnacipran has a 2-fold greater potency for norepinephrine.
Levomilnacipran -Fetzima Levomilnacipran is indicated for the treatment of major depressive disorder (MDD). – Milnacipran is indicated for the management of fibromyalgia. Levomilnacipran is not approved for the management of fibromyalgia. Levomilnacipran undergoes desethylation to form desethyl levomilnacipran by CYP 3A4, approximately 58% of the dose is excreted in urine as unchanged levomilnacipran. N-desethyl levomilnacipran is the major metabolite excreted in the urine and accounted for approximately 18% of the dose. The elimination T1/2 is ~12 hours vs. 6-8 hours for milnacipran

Levomilnacipran -Fetzima Increased Heart Rate and Blood Pressure: In short-term clinical studies, levomilnacipran treatment was associated with a mean increase in heart rate of 7.4 beats per minute (bpm) compared to a mean decrease of 0.3 bpm in placebo- treated patients. – Heart rate increase in levomilnacipran-treated patients receiving doses of 40 mg, 80 mg and 120 mg was 7.2, 7.2, and 9.1 bpm. In the short-term, placebo-controlled MDD studies, the mean increase from initiation of treatment in systolic BP was 3 mm Hg and diastolic BP was 3.2 mm Hg, as compared to no change in the placebo group. There were no dose-related changes in systolic and diastolic blood pressure observed. In patients exposed to one-year, open-label treatment of levomilnacipran (doses range from 40-120 mg once daily), the mean change from initiation of treatment in systolic BP was 3.9 mm Hg and diastolic BP was 3.1 mm Hg.
Levomilnacipran -Fetzima FDA BOX WARNING: SUICIDAL THOUGHTS AND BEHAVIORS – Increased risk of suicidal thinking and behavior in children, adolescents and young adults taking antidepressants. – Monitor for worsening and emergence of suicidal thoughts and behaviors. (this includes daily monitoring by families and caregivers for any changes in behaviors, emergence of agitation or irritability). – Not approved for use in pediatric patients
Levomilnacipran -Fetzima Drug Interactions: Monoamine Oxidase Inhibitor (MAOI), Linezolid or Methylene Blue - At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with levomilnacipran. Conversely, at least 7 days should be allowed after stopping levomilnacipran before starting an MAOI antidepressant. With linezolid or intravenous methylene blue there is an increased risk of serotonin syndrome. Strong Inhibitors of Cytochrome P450 (CYP3A4) including (ketoconazole, clarithromycin, ritonavir) – limit the dose of levomilnacipran to no more than 80 mg/day
Levomilnacipran -Fetzima Serotonin Syndrome: Serotonin syndrome has been reported with SSRIs and SNRIs, both when taken alone, but especially when co- administered with other serotonergic agents (including triptans, tricyclics, fentanyl, lithium, tramadol, tryptophan, buspirone and St. Johns Wort). – symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Levomilnacipran -Fetzima Dosage: Recommended dose: 40 mg to 120 mg once daily with or without food. Initiate dose at 20 mg once daily for 2 days and then increase to 40 mg once daily. Based on efficacy and tolerability, increase dose in increments of 40 mg at intervals of 2 or more days. The maximum recommended dose is 120 mg once daily. Take capsules whole; do not open, chew or crush. Renal Impairment: Do not exceed 80 mg once daily for moderate impairment (creatinine clearance of 30-59 ml/min). Do not exceed 40 mg once daily for severe renal impairment (creatinine clearance of 15-29 ml/min). Discontinuation: Reduce dose gradually whenever possible Cost: 20, 40, 80 and 120 mg caps - $194.28/30 caps all sizes WAC
Levomilnacipran -Fetzima CONCLUSION: Levomilnacipran is approved only for the treatment of MDD, while the racemic mixture, milnacipran, is approved only for the treatment of fibromyalgia. There are no head-to-head clinical trials of either of these drugs or against other SNRIs in the treatment of MDD or fibromyalgia. Both drugs are SNRIs and have similar contraindications, warnings, and precautions. Without head-to-head comparisons in studies lasting longer than 11 weeks, the value of this drug is unknown.

Measurement-Based Care Measurement-based care (MBC) promotes the use of rating scales or questionnaires to measure symptoms, side effects and adherence at every visit as well as guide tactics to modify dosage and treatment duration. Currently, most clinicians do not routinely use specific measures of depressive symptoms at patient visits. Rather, they tend to use global measures instead of specific symptoms measures. Results from the STAR*D study show that the use of MBC may lead to greater remission rates than those seen in efficacy studies for patients with chronic depression. (Am J Psychiatry 2006;163:28-40)
Choice of Antidepressant Medication & Dosing Choice of treatment should be guided by: Patients prior response to treatment Tolerability Psychiatric and medical comorbidity Concurrent medications Family history of response Patient preference Cost Patient education and family involvement play critical roles in ensuring patient adherence to treatment.
APA Practice Guideline for the Treatment of Patients With Major Depressive Disorder 3rd Ed -2010 To reduce the risk of relapse, patients who have been treated successfully with antidepressant medications in the acute phase should continue treatment with these agents for 4–9 months [I]. In general, the dose used in the acute phase should be used in the continuation phase [II].
APA Practice Guideline for the Treatment of Patients With Major Depressive Disorder 3rd Ed -2010 When pharmacotherapy is being discontinued, it is best to taper the medication over the course of at least several weeks [I]. To minimize the likelihood of discontinuation symptoms, patients should be advised not to stop medications abruptly and to take medications with them when they travel or are away from home [I].

Canagliflozin - Invokana Canagliflozin is a sodium-glucose co- transporter 2 (SGLT2) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. The FDA has asked for five postmarketing studies for the drug including a cardiovascular outcomes trial, an enhanced pharmacovigilance program, a bone safety study and two pediatric studies Available as 100 mg and 300 mg tablets – Cost: $277.41/30 tabs WAC both sizes
Canagliflozin - Invokana Mechanism of Action Sodium-glucose co-transporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RTG), and thereby increases urinary glucose excretion. Maximal suppression of mean RTG over the 24 hour period was seen with the 300 mg daily dose to approximately 70 to 90 mg/dL in patients with type 2 diabetes in Phase 1 studies.
Canagliflozin - Invokana Warnings and Precautions Hypotension - canagliflozin causes intravascular volume contraction. Symptomatic hypotension can occur after initiating csanagliflozin particularly in patients with impaired renal function (eGFR less than 60 mL/min/1.73 m2), elderly patients, patients on either diuretics or medications that interfere with the renin-angiotensin-aldosterone system (e.g., angiotensin- converting-enzyme [ACE] inhibitors, angiotensin receptor blockers [ARBs]), or patients with low systolic blood pressure. Before initiating canagliflozin in patients with one or more of these characteristics, volume status should be assessed and corrected. Monitor for signs and symptoms after initiating therapy.

Canagliflozin - Invokana Patients with Renal Impairment Canagliflozin increases serum creatinine and decreases eGFR. – Patients with hypovolemia may be more susceptible to these changes. – No dose adjustment is needed in patients with mild renal impairment (eGFR of 60 mL/min/1.73 m2 or greater). – The dose of canagliflozin is limited to 100 mg once daily in patients with moderate renal impairment with an eGFR of 45 to less than 60 mL/min/1.73 m2. – Canagliflozin should be discontinued or not be initiated in patients with an eGFR less than 45 mL/min/1.73 m2. – Assessment of renal function is recommended prior to initiation of canagliflozin therapy and periodically thereafter.
Canagliflozin - Invokana Genital Mycotic Infections: Canagliflozin increases the risk of genital mycotic infections. Patients with a history of genital mycotic infections and uncircumcised males were more likely to develop genital mycotic infections. (10-12% in women and 3- 4% in men). Urinary Tract Infections: 4-6% of patients Increased Urination/Polyuria: 4-6% of patients
Canagliflozin Efficacy Cana
Canagliflozin - Invokana Recommended Dosage The recommended starting dose of canagliflozin is 100 mg once daily, taken before the first meal of the day. In patients tolerating 100 mg once daily who have an eGFR of 60 mL/min/1.73 m2 or greater and require additional glycemic control, the dose can be increased to 300 mg once daily. The dose is limited to 100 mg once daily in patients with moderate renal impairment with an eGFR of 45 to less than 60 mL/min/1.73 m2. Canagliflozin should not be initiated in patients with an eGFR less than 45 mL/min/1.73 m2.
Dapagliflozin-Farxiga (far-SEE-guh) by Astra Zeneca December 13, 2013 The FDA Advisory panel voted 10 to 1 in favor of approval for AstraZeneca and Bristol-Myers Squibb's diabetes drug dapagliflozin. – follows the FDA's previous rejection of dapagliflozin in January 2012, primarily due to concerns about bladder cancer and liver toxicity. – all the panelists strongly advised that the sponsors move forward with a planned large postmarketing trial designed to provide enough statistical power to answer outstanding questions about cardiovascular safety as well as malignancy and liver toxicity. DECLARE-TIMI 58 trial has already begun recruiting the first of an anticipated 17,150 patients.
Dapagliflozin -Farxiga It is an inhibitor of the sodium-glucose cotransporter 2 (SGLT2), expressed in the proximal renal tubules, responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Dapagliflozin 10 mg per day in patients with type 2 diabetes mellitus for 12 weeks resulted in excretion of approximately 70 grams of glucose in the urine per day.
Dapagliflozin -Farxiga Pharmacokinetics: Absorption – Cmax and AUC are dose proportional and peak levels occur at 2 hours after oral dosing, oral bioavailability is ~78% (91% protein bound) Metabolism - metabolism of dapagliflozin to inactive metabolites is primarily mediated by UGT1A9; – UDP-glucuronosyltransferase, an enzyme of the glucuronidation pathway that transforms small lipophilic molecules, into water-soluble, excretable metabolites Elimination – primarily renal with a mean elimination T1/2 of ~12.9 hours

Dapagliflozin - Farxiga Renal-related adverse reactions, including renal failure and blood creatinine increase, were more frequent in patients treated with dapagliflozin – Overall population Patients (%) with at least one event: 6.7% (n=2026 up to 104 wks) – 65 years of age and older: 14.0% (n=620) – eGFR 30 and <60 mL/min/1.73 m2: 28.3% (n=251) – 65 years of age and older and eGFR 30 and <60 mL/min/1.73 m2: 35.1% (n=134)
Dapagliflozin - Farxiga Across 22 clinical studies, newly diagnosed cases of bladder cancer were reported in 10/6045 patients (0.17%) treated with dapagliflozin and 1/3512 patient (0.03%) treated with placebo/comparator. After excluding patients in whom exposure to study drug was less than one year at the time of diagnosis of bladder cancer, there were 4 cases with dapagliflozin and no cases with placebo/comparator. Bladder cancer risk factors and hematuria were balanced between treatment arms at baseline. There were too few cases to determine whether the emergence of these events is related to dapagliflozin.
Dapagliflozin - Farxiga Dosage: The recommended starting dose of dapagliflozin is 5 mg once daily, taken in the morning, with or without food. In patients tolerating 5 mg once daily, the dose can be increased to 10 mg once daily Cost - $277.46/30 tabs 5 or 10 mg WAC – Correct volume depletion prior to starting – Monitor renal function prior to initiation of therapy and periodically thereafter – Should not be initiated in patients with an eGFR less than 60 mL/min/1.73 m2 – Should be discontinued when eGFR is persistently less than 60 mL/min/1.73 m

Harmony 7 Trial Albiglutide vs Liraglutide in a randomized, phase 3, open-labeled, non-inferiority, multicenter study in 812 patients with type 2 diabetes inadequately controlled with metformin, thiazolidinediones, sulfonylureas, or any combination of these oral agents. – The baseline A1c was 8.16%, age was 55.6 years, BMI was 32.8 kg/m2, and duration of diabetes was 8.4 years. – Patients were randomized to 32 weeks of treatment with albiglutide once weekly or liraglutide once daily. The albiglutide group started with albiglutide 30 mg once a week for 6 weeks, then the dose was increased to 50 mg once weekly for 26 weeks. The liraglutide group started with liraglutide 0.6 mg once daily for 1 week, then 1.2 mg once daily for 1 week, and finally 1.8 mg at week 3 for the remaining 29 weeks.
Harmony 7 Trial Results: Change in A1c from baseline was 0.78% with albiglutide and 0.99% with liraglutide; treatment difference was 0.21%. Weight loss was 0.64 kg with albiglutide and 2.19 kg with liraglutide. Fasting plasma glucose was 22.1 mg/dL from baseline with albiglutide and 30.4 mg/dL with liraglutide (P = 0.05).
Harmony 7 Trial GI tract adverse reactions occurred in 35.9% of the albiglutide group and 49% of the liraglutide group. Fewer patients had nausea (9.9% vs 29.2%) and vomiting (5% vs 9.3%) with albiglutide compared with liraglutide. Hypoglycemia occurred in 16.3% of the albiglutide group and 20.8% of the liraglutide group. Injection-site reactions were more common with albiglutide than liraglutide (12.9% vs 5.4%).
Albiglutide – Tanzeum The FDA is requiring the following post- marketing studies for Tanzeum: – a clinical trial to evaluate dosing, efficacy, and safety in pediatric patients; – a medullary thyroid carcinoma (MTC) case registry of at least 15 years duration to identify any increase in MTC incidence related to Tanzeum; – a cardiovascular outcomes trial (CVOT) to evaluate the cardiovascular risk of Tanzeum in patients with high baseline risk of cardiovascular disease.
AFREZZA® (insulin human [rDNA origin]) Inhalation Powder Reviwed by FDA Endocrinologic and Metabolic Drug Advisory Committee 4-1-2014 An ultra -rapid acting dry powder insulin for inhalation to improve glycemic control in adult and pediatric patients with diabetes mellitus Type 1 and 2 who require insulin by MannKind Corp. Technosphere Insulin Inhalation Powder (TI) is composed of recombinant human insulin and fumaryl diketopiperazine (FDKP), an inert excipient. It is administered with the breath-powered, dry powder Gen2 inhaler
AFREZZA® (insulin human [rDNA origin]) Inhalation Powder Users self-administer TI by oral inhalation using the Gen2 inhaler. The to-be-marketed cartridges contain either 0.35 mg (10 U) or 0.7 mg (20 U) of insulin. The 10 U cartridge approximates 3 units of sc injected insulin (and is labeled as 3 units) and the 20 U cartridge approximates 6 units of sc injected insulin (and is labeled as 6 units). The Gen2 inhaler is small, discrete, easy to use, and is discarded and replaced every 15 days.
AFREZZA® (insulin human [rDNA origin]) Inhalation Powder No cleaning is required. As a breath-powered inhaler, it relies on a persons inhalation effort to reproducibly deliver TI to the pulmonary tract. Replaced every 15 days.
AFREZZA® (insulin human [rDNA origin]) Inhalation Powder Technosphere insulin inhaltion has a more rapid onset of insulin action and shorter duration of effect, as measured by the glucose infusion rate (GIR) during a euglycemic clamp study, when compared with sc Human Regular or insulin lispro. Some data suggest that there is less weight gain (even a modest loss in some patients) and less risk of hypoglycemia (1.7% vs. 2.3%) than with injectable insulin but there was also more cough (26.9% vs. 5.2%), a slightly greater reduction in FEV1 (mean difference, was -40 mL at 3 months and -45 mL at 24 months), and disappeared upon discontinuation of TI therapy with the inhaled insulin. Patients with asthma and COPD should not be given inhaled insulin, proposed labeling will say contraindicated!
AFREZZA® (insulin human [rDNA origin]) Inhalation Powder
On April 1, 2014 the FDA Endocrinologic and Metabolic Drug Advisory Committee voted 13-1 with one abstention to approve Afrezza for Type 1 diabetics, and 14-0 with one abstention for Type 2 diabetics. – While the FDA isnt required to follow the panels recommendation, it rarely contradicts it. An official determination is expected by April 15. Prior to the meeting FDA staff report worried investors in the stock, as it noted the drugs potential risk of causing lung infections and bronchial spasms and coughing that caused some patients to stop treatment. Staff also questioned the accuracy of insulin doses in MannKinds clinical studies. Concern was also raised about the potential for lung cancer with long-term therapy as was seen with Pfizers Exubera.

Extract from Short Ragweed (Ambrosia artemisiifolia) Pollen – Ragwitek by Merck April 17, 2014 FDA approved Ragwitek, the first allergen extract administered under the tongue (sublingually) to treat short ragweed pollen induced allergic rhinitis (hay fever), with or without conjunctivitis (eye inflammation), in adults 18 years through 65 years of age. Treatment with Ragwitek is started 12 weeks before the start of ragweed pollen season and continued throughout the season. The first dose is taken in a health care professionals office where the patient is to be observed for at least 30 minutes for potential adverse reactions. After the first dose, patients can take Ragwitek at home.
Extract from Short Ragweed (Ambrosia artemisiifolia) Pollen – Ragwitek The safety and effectiveness of Ragwitek was evaluated in studies conducted in the United States and internationally. Safety was assessed in approximately 1,700 adults. The most commonly reported adverse reactions by patients treated with Ragwitek were itching in the mouth and ears and throat irritation. Of the 1,700 adults, about 760 were evaluated to determine effectiveness. Some patients received Ragwitek; others received an inactive substitute (placebo). The patients reported their symptoms and additional medications needed to get through the allergy season. During treatment for one ragweed pollen season, patients who received Ragwitek experienced approximately a 26 percent reduction in symptoms and the need for medications compared to those who received a placebo.
Extract from Short Ragweed (Ambrosia artemisiifolia) Pollen – Ragwitek The dosage of the tablets proposed for use in the US is 12 Amb a 1 – U of extract derived from short ragweed (Ambrosia artemisiifolia) pollen. (Equivalent to about 1 mcg of Amb a 1) To measure symptoms, the sponsors used the average rhinoconjunctivitis Daily Symptom Score (DSS). The DSS is the sum of six individual rhinoconjunctivitis symptom scores with possible values of 0 (absent) to 3 (severe). The six symptoms that are scored are: runny nose, blocked nose, sneezing, itchy nose, gritty feeling/red/itchy eyes, and watery eyes. The maximum DSS is 18.
Extract from Short Ragweed (Ambrosia artemisiifolia) Pollen – Ragwitek To measure medication use, the sponsors use the average rhinoconjunctivitis Daily Medication Score (DMS). – The DMS is the sum of scores that are assigned to each medication (IE antihistamines 6, topical steroids 8 and systemic steroids 16 with a max scores of 36) The primary efficacy endpoint for each of the studies was the total combined score (TCS) over the peak of ragweed season. The TCS is the sum of DSS (maximum 18) and DMS (maximum 36). The maximum TCS is 54.
