1 New Drugs 2016 The Good, the Bad, & the Worthless
Bill Origer MD OAFP March 11, 2016

2 Disclosure No commercial financial support
After the talk, you will understand why

3 Disclaimers Not a comprehensive study of diseases
Based on high quality published research References & boring details available Prices are approximate & may vary New information is continuous anything could change I could be wrong

4 Another disclaimer Research applies to populations
Physicians treat individuals Medicine has thousands of unique & unusual people and situations Do the right thing for each patient There are times when a 4th or 5th choice is the best option for that patient

5 How did I get into this?? 20 yrs private practice Albany, 1977 – 1996
Variety of admin jobs & part-time practice Faculty, Samaritan Family Medicine Residency, Corvallis Oregon Health Resources Commission , Chair, Pharmaceutical Subcommittee ‘08-’11 Oregon Preferred Drug List Committee 2010 Oregon P & T Committee, Chair, My credibility in this world is the strength of evidence If it’s evidence based, it’s not you vs me, but a discussion of the evidence In 2000, “Bill, put this drug on the formulary, it works better.” “What’s the evidence for that?” “ Ummmm.” In 2006, “ Bill I’ve got an article I want you to read.”

6 Same efficacy & toxicity within category May be differences in side effects, dosing, duration of action, price Alzheimer’s drugs ACE Inhibitors Angiotensin receptor blockers ADHD stimulant drugs Inhaled steroids for asthma Inhaled anti-cholinergics β agonists for asthma Inhaled nasal steroids α blockers for PBH 5 α-reductase inhibitors- BPH Estrogens for menopause Oral contraceptives Muscle relaxants NSAIDS Ophthalmic steroids Ophthalmic anti-inflammatories Growth hormone products Benzodiazepine receptor agonist sedatives Opioids for long term use H2 blockers PPIs Statins (adjusted for potency) Triptans for migraine Anticholinergics & others for overactive bladder DPE-5 inhibitors for erectile 2nd generation antidepressants Based on rigorous evidence reviews by Oregon Health Resources Commission & Oregon P & T Committee, there are no major difference in efficacy or toxicity among drugs in the following categories. There may be differences in side effects, dosing, and duration of action, and price\ Growing evidence of class effect of beta blockers, but not yet conclusive

7 The Good

8 Newer anticoagulants Safety & efficacy same as warfarin for stroke prevention with atrial fib, and acute DVT in uncomplicated patients Concerns: no way to monitor, bid dose (dabigatran & apixaban) caution w renal impairment, high cost (~$300/mo) Edoxaban (Savaysa) no comparative data to others Only dabigitran is reversible 90% of OHP patients still on warfarin Oregon P & T Sept 2015; Medical Letter 3/15/2015 dabigatran etexilate (Pradaxa), rivaroxaban (Xarelto), and apixaban (Eliquis)  Edoxaban (Savaysa) - The Fourth New Oral Anticoagulant

9 Idarucizumab (Praxbind) Antidote for dabigatran (Pradaxa)
Human monoclonal antibody Binds to dabigatran w higher affinity than dabigatran binds to thrombin Works only for dabigitran. Immediate onset, blood levels <20 ng/ml 93% at 12 hr, 79% at 24 hrs. Dose - IV bolus 5 gm, $3500/dose Limited data – single arm trial, 90 patients, 92% had normal hemostasis for surgery The Medical Letter 11/23/2015

10 Drugs past expiration date
Dates written by legal department Single episode of toxicity of expired drug – tetracycline 1963 Dept Defense Study: 3005 lots of 122 meds, ave. 66 mo. past date Solid drugs, unopened container, room temperature >90% of potency 5 yrs past date Heat & humidity speed aging Solutions, suspensions less stable, especially to freezing Epi-pens loose potency after expiration The Medical Letter 12/7/2015

11 Albuterol powder MDI (ProAir RespiClick)
Existing albuterol inhalers - dilute solution w propellant. Requires coordination between actuation of the device and inspiration, or the use of a spacer Dry powder inhalers are breath-actuated, and do not require an initial priming dose. The patient must be able to take a rapid deep inhalation to activate the inhaler. Contains a dose counter Opening the mouthpiece prepares a dose for use & causes the counter to count down one dose. Closing the cap without inhalation wastes that dose. Price $50 per inhaler (200 doses,) similar to other albuterol MDIs. This device may be easier for some patients to use. The Medical Letter 10/26/2015

12 Hepatitis C Facts Of 100 persons infected with HCV, approximately
75–85 will go on to develop chronic infection 60–70 will go on to develop chronic liver disease 5–20 will go on to develop cirrhosis over a period of 20–30 years 1–5 will die from the consequences of chronic infection (liver cancer or cirrhosis) CDC website accessed 2/22/2015

13 Beware of Hep C Guidelines
American Association for the Study of Liver Diseases (AASLD) Infectious Disease Society of America (IDSA) Hepatitis C Guidelines Not evidence based Majority of members with conflict of interest

14 Levels of evidence 1A Meta-analysis of randomized controlled trials
1B At least one randomized controlled trial 2A At least one controlled study without randomization 2B At least one type of quasi-experimental study 3 Descriptive studies, such as comparative studies, correlation studies, or case-controlled studies 4 Expert committee reports or opinions and/or clinical experience of respected authorities

15 American Association for the Study of Liver Diseases (AASLD) Infectious Disease Society of America (IDSA) Definitions of Evidence Classification Description Class I Conditions for which there is evidence and/or general agreement that a given diagnostic evaluation, procedure, or treatment is beneficial, useful, and effective Class II Conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness and efficacy of a diagnostic evaluation, procedure, or treatment Class IIa Weight of evidence and/or opinion is in favor of usefulness and efficacy Class IIb Usefulness and efficacy are less well established by evidence and/or opinion Class III Conditions for which there is evidence and/or general agreement that a diagnostic evaluation, procedure, or treatment is not useful and effective or if it in some cases may be harmful

16 Guideline Myths Myth - Treat everyone
<20% get cirrhosis over yrs; <5% die from disease Cost would double total annual drug budget for OHP open card Myth - treat early Based on “modeling studies” – IE speculation Myth - Active drug abuse not a barrier Only study done on opioid addicts in treatment with suboxone or methadone – they did well, but can’t extrapolate Anecdotal reports of re-infection in addicts after tx Myth – alcohol abuse not an obstacle Studies exclude active drug or alcohol users – no data

17 Priority - sickest Advanced fibrosis (METAVIR F3),compensated cirrhosis (METAVIR F4) OR radiologic, lab, or clinical evidence of cirrhosis without ongoing progressive decompensation (MELD score 8 -11), Expected survival from other conditions >5 years Extrahepatic manifestations of hepatitis C Type 2 or 3 cryoglobulinemia with end-organ manifestations (vasculitis) Proteinuria, nephrotic syndrome, or membranoproliferative glomerulonephritis

18 Priority - sickest Patient is listed for a transplant and it is essential to prevent recurrent hepatitis C infection post-transplant Post-transplant patients with Stage 4 fibrosis Post-transplant patients with fibrosing cholestatic hepatitis due to HCV infection Oregon P & T Jan 2016

19 Priority – best chance for success
Abstinent from illicit drug, marijuana use, AND alcohol abuse for 6 months or longer Able to participate & cooperate in treatment Consultation with hepatologist, GI or ID specialist, or other physician with experience in treatment of Hepatitis C

20 Hep C summary New drugs are better & less toxic
Studies are poor quality & short Guidelines are not scientific Competition dropping prices, but still outrageous More drugs in the pipeline Treat the sickest, no hurry for most Cost still $40,000 – 80,000

21 Naloxone auto injector (Evzio)
Auto-injector syringes containing 0.4 mg naloxone for opioid overdose Original price $250/pkg As of 2/24/2016: pkg of 2 syringes: $820 Off-label: a standard dose, 0.4mg of injectable naloxone ($17-22) may be used intranasally. The Medical Letter 6/9/2014; goodrx.com

22 Platelet inhibitors after PCI
Dual antiplatelet therapy (DAPT) consisting of aspirin plus a P2Y12 receptor antagonist is after drug‐eluting stent (DES) 12 months by the Am Coll of Cardiology/Am Heart Asso (ACC/AHA) 6-12 months by European guidelines followed by aspirin monotherapy extended therapy (>12 months) compared with 12‐month therapy reduction in stent thrombosis (NNT 100‐250) and MI (NNT 50‐125), but increased risk of major bleeding (NNH 111‐325). increase in all‐cause mortality with extended DAPT beyond one year 2.0% vs. 1.5%; NNH 200 driven by non‐cardiovascular events. Further studies are needed the optimal duration of therapy DAPT one year in most patients receiving a DES high CV risk patients considering longer term use (up to 30 months) high bleeding risk consider <6 months. Oregon P & T July 2015

23 Newer drugs for Diabetes
A recent systematic review found insufficient evidence to compare health outcomes of the newer diabetes medications and combinations Studies underway Be skeptical of single studies CV benefit of metformin, insulin, sulfonylureas based on meta-analysis of large studies Evidence‐based Practice Center for the Drug Effectiveness Review Project. OHSU Portland, OR CV benefit of metformin, insulin, sulfonylureas based on meta-analysis of large studies.

24 Ophthalmic steroids & anti-inflammatories
High quality evidence - no difference in efficacy/effectiveness or in safety between ophthalmic corticosteroid agents High quality evidence - no difference in efficacy/effectiveness or in safety among ophthalmic nonsteroidal anti‐inflammatory drugs Oregon P & T 5/28/2016 Current Preferred Agents Current Non‐Preferred Agents Ophthalmic Corticosteroids Dexamethasone (MAXIDEX) suspension Dexamethasone sodium phosphate suspension Fluorometholone (FML; FML S.O.P.; FLUOR‐OP) suspension Loteprednol etabonate (LOTEMAX) suspension Prednisolone (OMNIPRED; PRED FORTE) suspension NON PREFERRED Dexamethasone sodium phosphate (DECADRON) ointment Difluprednate (DUREZOL) emulsion Fluorometholone (FML FORTE) suspension Fluorometholone acetate (FLAREX) suspension Loteprednol etabonate (ALREX) suspension Loteprednol etabonate (LOTEMAX) gel and ointment Prednisolone acetate (PRED MILD) suspension Prednisolone sodium phosphate (INFLAMASE MILD; INFLAMASE FORTE) suspension Rimexolone (VEXOL) suspension Ophthalmic Non‐steroidal Anti‐inflammatory Drugs (NSAIDs) PREFERRED Diclofenac sodium (VOLTAREN) solution Flurbiprofen (OCUFEN) solution Ketorolac tromethamine (ACULAR; ACULAR LS) solution Bromfenac (PROLENSA) solution Ketorolac (ACUVAIL) solution Nepafenac (ILEVRO; NEVANAC) suspension

25 Asthma/COPD Tiotropium/olodaterol (Stiolto™ Respimat®) insufficient evidence of comparative efficacy or safety between tiotropium-olodaterol and other drugs for the management of COPD Olodaterol - lack of quality evidence for clinical effectiveness. Fluticasone furoate (Arnuity™ Ellipta®) same as any other inhaled steroid Oregon P & T Sept 24, 2015

26 Insulin glargine (Lantus) Insulin detemir (Levemir)
Insufficient comparative evidence that evaluates long‐term outcomes (ie, vascular outcomes, mortality or cancer) between insulin detemir and glargine products No clinically relevant difference in efficacy or safety of the two long acting agents Insulin degludec (Tresiba) is noninferior to insulin glargine & insulin detemir in lowering HbA1c Oregon P & T Nov 2015; Medical Letter 12/7/2105

27 Insulin degludec (Tresiba)
8 open‐label, randomized controlled trials Comparisons included insulin glargine, insulin detemir, and sitagliptin Low strength evidence - non‐inferior to insulin glargine or detemir at A1c reduction Open‐label study design prohibits a fair comparison for adverse effects Insufficient evidence to show any effect on mortality, or vascular outcomes.

28 Insulin degludec and insulin aspart Ryzodeg®
Similar A1c lowering as detemir/aspart Insufficient evidence to determine the effect of degludec/aspart on mortality, & vascular outcomes Oregon P & T Dec 2015

29 Fluoroquinolones Moderate quality evidence: no difference in effectiveness of fluoroquinolones to susceptible bacteria Ofloxacin - highest risk of tendon injury levofloxacin - least risk Oregon P & T 5/28/2015

30 Topical analgesics Moderate quality evidence: topical NSAIDs are safe and effective for acute musculoskeletal pain over 1 to 2 weeks Insufficient evidence to compare efficacy or safety among topical analgesics. Topical 8% capsaicin improves neuropathic pain more than lower concentrations Evidence of long‐term safety is insufficient Insufficient evidence exists for efficacy of 5% topical lidocaine patches for neuropathic pain Insufficient evidence to compare topical VS oral NSAIDS for efficacy or safety Oregon P & T Nov 2015

31 Maybe good

32 Flibanserin (Addyi) Hypoactive sexual desire in menopausal women
Mechanism unknown Agonist serotonin-HT1A Antagonist serotonin-HT2A 100mg daily at hs, $800/month Somnolence, sedation, fatigue 21% Hypotension & syncope, worse w alcohol Concurrent alcohol use contraindicated

33 Flibanserin (Addyi) Three 24-week studies, DAISY, VIOLET, BEGONIA
End points on self-rating scales: Increase in satisfying sexual events over 4 wks: 0.8 to 1.0 compared to placebo (p<0.05) Mean increase in peak sexual desire score at 24 wks: not significant 2 studies, 3rd study: increase over placebo 0.3 on 6 point scale (p<0.05) Overall response rate 8-13% compared to placebo Long term safety & efficacy unknown Medical Letter 9/28/2015

34 Sacubitril/valsartan (Entresto)
New category of drug neprilysin inhibitor Neprilysin degrades natriuretic peptides Natriuretic peptides prevent progression of ventricular dysfunction & remodeling in animals Neprilysin also degrades angiotensin, endothelin- 1, opioids, bradykinin, & amyloid-β peptide. JAMA 12/7/2015

35 Sacubitril/valsartan Theoretical risks
Neprilysin also degrades angiotensin, opioids, endothelin- 1, bradykinin, & amyloid-β peptide Used with ARB due to degradation of angiotensin Amyloid-β peptide has protective effects on Alzheimer's & macular degeneration Long term studies of neurocognitive effects due in I think we can wait.

36 Sacubitril/valsartan Clinical study
8399 pts randomized, CHF, EF 29%, NYHA Class II or III, on diuretic and β blocker Comparison: enalapril 10 mg bid End points at 27 months: composite CV death or admission for CHF; all cause mortality Single blind run-in for dose toleration. 20% of subjects eliminated before randomization. NEJM 9/11/2014 NYHA I No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath). II Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath). III Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea. IV Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest.  If any physical activity is undertaken, discomfort increases.

37 Sacubitril/valsartan Clinical study
Terminated early, 27 vs 36 months CHF admission: 12.8% vs 15.6% control Absolute risk reduction 2.8% NNT 36 CV mortality: 16.5% vs 13.3% control Absolute risk reduction 3.2% NNT 31 NNT similar to ACE I alone NNT for beta blockers alone much better about half

38 Sacubitril/valsartan Clinical study- Problems
Not comparable dose of enalapril – should be 20 mg bid Higher ARB dose could be reason for benefit 20% of both arms dropped out due to drug intolerance (in addition to 20% eliminated at run-in) Large single study, not replicated Long term toxicity unknown Similar

39 Sacubitril/valsartan analysis
NNT 36 patients for 27 months to prevent one admission and one death. Assume $375/mo cost 36 pt x 27mo = 972 months x $375/mo = $364,500 – drug cost to prevent one hospitalization  Medicare 2015 DRG payments for CHF hospitalization $3,966 to $8,855 Total drug cost is 41-92X more than cost of hospitalization. Oregon State Drug Review Dec 2015; cost: Goodrx.com 2/16/2016

40 Sacubitril/valsartan Summary
Interesting concept Not ready for general use Need more/better studies Standard therapy better studied, costs 100X less

41 Rifaximin for hepatic encephalopathy
Low quality evidence - adding rifaximin 550 mg bid to lactulose is superior to lactulose alone at preventing HE Low quality evidence -adding rifaximin to lactulose in hospitalized patients with HE is superior to lactulose alone Studies have not been conducted in the U.S. - off label use Insufficient evidence for the use of rifaximin without lactulose for prevention or treatment Cases reports of Clostridium difficile infection - uncommon, but incidence unknown. $1,800/month, lactulose $50/mo Oregon P & T 5/28/2105

42 Fidaxomicin (Dificid) for C diff
Moderate evidence - oral vancomycin is superior to oral metronidazole in mild and severe C difficile infection (CDI) Moderate evidence - oral vancomycin and oral fidaxomicin same for first episode of CDI Insufficient evidence to compare metronidazole and fidaxomicin. Insufficient evidence to support fidaxomicin alone for complicated or fulminant CDI First recurrence – repeat previous tx Moderate quality evidence fidaxomicin is superior to oral vancomycin at preventing recurrences of CDI Insufficient evidence for the combination of 2 oral antibiotics Fidaxomicin $3,500 - $3,700 for 10 days Oregon P & T 5/28/2016

43 The BAD

44 Ivabradine (Corlanor) for CHF
Slows heart rate by inhibiting cardiac pacemaker If  current. No effect on ventricular repolarization or myocardial contractility Does not reduce all‐cause or CV mortality compared to placebo Low quality evidence - ivabradine may reduce hospitalizations for CHF by 4.7% compared to placebo (15.9% vs. 20.6%.) Majority of patients were in Eastern European countries with higher rate of hospitalization for CHF than USA. Cannot extrapolate results to US. Increases risk for atrial fibrillation. Do not use in patients with atrial fibrillation, discontinue if a fib develops $380 - $400/month Oregon P & T July 2015 60 tablets of Corlanor 5mg $ In a trial in 10,917 patients with coronary artery disease and stable heart failure (BEAUTIFUL), ivabradine did not significantly affect the primary composite endpoint of cardiovascular death, hospitalization for acute MI, or hospitalization for new-onset or worsening heart failure, compared to placebo.3 In another placebo-controlled trial in 19,102 patients who had coronary artery disease without clinically evident heart failure (SIGNIFY), ivabradine also did not significantly affect the primary endpoint, a composite of cardiovascular death or nonfatal MI. Moreover, a prespecified subgroup analysis in patients with more than minimal angina pectoris found a significantly higher incidence of the primary endpoint with ivabradine (7.6% vs 6.5% with placebo).4

45 Eluxadoline (Viberzi) for irritable bowel
Mu-opioid receptor, Schedule IV narcotic $960/mo 2 unpublished studies weeks, vs placebo reported 12 week endpoints, 75 & 100 mg doses Primary endpoint: improvement in the daily worst abdominal pain score by ≥30% as compared to the baseline weekly average AND a reduction in the Bristol Stool Score to <5 on at least 50% of the days in a 12-week time interval. Improvement in daily worst abdominal pain in the absence of a concurrent bowel movement was also considered a response day.

46 Eluxadoline (Viberzi) for irritable bowel
Even if you understand what that means, it did not work very well. At 12 weeks: Study 1: 24-25% responded to drug, 17% pcbo Study 2: 29-30% responded to drug, 16% pcbo 26 wks, 75 mg worse than placebo, 100 mg similar to placebo No improvement in abd pain vs pcbo at 12 wks Medical Letter 1/4/2016; Viberzi package insert

47 Eluxadoline (Viberzi) for irritable bowel
High dose - euphoria in 14-28% of patients, 0-5% on placebo Sphincter of Oddi spasm 1%, if no gallbladder 4% Risk of pancreatitis if >3 drinks/day This drug has it all: High cost, high toxicity, addiction risk, low efficacy!!

48 SGLT2 Inhibitors risks Induce renal glycosuria – risks: dehydration, hypotension, hyperkalemia, mycotic genital infections, renal failure, especially in elderly New FDA warnings - case reports of: Ketoacidosis, some with normal blood glucose. Mechanism- increased fat metabolism Pyelonephritis & urosepsis. Mechanism - glucosuria Loss of bone density & increased fractures. Mechanism – increased renal reabsorption of phosphate Incidence & long term risk unknown Oregon State Drug Review Feb Medical Letter 10/12/2015

49 SGLT2 Inhibitors ? CV benefit
Single study 7020 pts with DM-2 & CV disease 590 sites, 42 countries Empagliflozin 10 or 25 mg vs placebo, 2.6 yrs Same incidence of MI & stroke Reduced CV death 3.7% vs 5.9 % placebo Reduced hospitalization for CHF 2.7% vs 4.1% Mechanism unknown Remain skeptical. NEJM 11/26/2015 Lots of patients in E Europe & Russia, Mexico, Brazil, Peru, Indonesia, Malaysia, India, Japan, Korea, Hong Kong, W Europe & USA

50 The Worthless

51 Rifaximin for irritable bowel
Non-absorbable antibiotic mg tid 14 days vs placebo, 12 week study Primary endpoint is squishy: Self reported relief of symptoms 2 of the first 4 weeks of tx. Would we use that for angina? 40.8% drug % pcbo Difference between tx & pcbo decreased w time. Gone at 12 weeks in 4/5 endpoints $1,176 Medical Letter 8/3/2015; NEJM 1/6/2011 Self reported relief of symptoms 2 of the first 4 weeks of tx. (would this endpoint be OK for Htn?) Recurrence rate 59% Remember CV benefits metformin, sulfonylurea, insulin well documented

52 Calcium & Vitamin D Mythology outweighs good studies by wide margin
Insufficient evidence on comparative efficacy among the different calcium formulations and among the different vitamin D formulations (USPSTF) recommends against routine screening of vitamin D levels in asymptomatic adults Calcium and vitamin D supplements lack evidence to support routine use Insufficient evidence to make strong conclusions Many references, me if you want specifics Vitamin D plus calcium had a small effect in reducing hip fractures (RR 0.84; 95% CI 0.74 to 0.96; p=0.01), which translates into 1‐9 fewer fractures per 1000 patients per year compared to controls.

53 Calcium supplements Small reduction in total fractures in women – 12 to 11%, vertebral fractures 1.5 to 1.3%. No benefit in hip or forearm fx Small increase in bone density 0.7 to 1.8% in hip, spine, femoral neck & forearm Decreases risk of pre-eclampsia & hypertension in pregnancy Four systematic reviews and meta‐analyses were available for updated evidence on the role of calcium supplementation on fracture risk, bone mineral density (BMD), hypertensive disorders in pregnancy and maternal and child outcomes. There is low strength of evidence from 26 trials that included mostly females that calcium supplementation may reduce total body fracture risk (RR, 0.89, 95% CI 0.81 to 0.96) and vertebral fractures (RR, 0.86; 95% CI, 0.74 to 1.00) regardless of dose. Absolute risk reduction for total body fractures was 1% favoring calcium over control (11% vs. 12%, respectively) and the absolute risk reduction for vertebral fractures was 0.2% (1.3% vs. 1.5%, respectively). No benefit was seen in hip or forearm fractures. Calcium supplements with vitamin D had similar results as calcium monotherapy. Studies of dietary calcium had no effect on fracture rates.  There is low strength of evidence from a systematic review and meta‐analysis of 59 trials that BMD is increased 0.7‐1.8% in the hip, lumbar spine, femoral neck, forearm and total body with calcium supplementation dosed 250‐2,500 mg daily.  There is moderate strength of evidence that calcium supplementation (≥1 g/day) decreases risk of pre‐eclampsia during pregnancy (RR 0.45; 95% CI, 0.31 to 0.65), with an incidence rate of 65/1000 in controls compared to a rate of 29/1000 in women treated with calcium. The risk of hypertension in this population is reduced with calcium supplementation compared to placebo (RR, 0.65; 95% CI, 0.53 to 0.81) as well as decreased incidence of preterm birth (79/1000 vs. 104/1000, respectively; RR, 0.76; 95% CI, 0.60 to 0.97).3 However, there is moderate strength of evidence that calcium supplementation in women not at increased risk for pre‐eclampsia does not lower risk of preterm birth. However, there is low quality evidence calcium supplementation may be associated with a low, but increased incidence of HELLP Syndrome (hemolysis, elevated liver enzymes, and low platelets) in pregnant females (16 vs. 6 with placebo).

54 Vitamin D Benefits May reduce incidence of falls in elderly women
may decrease the number of falls (RR 0.66; 95% CI, 0.50 to 0.88; I2=65%) in elderly women. vitamin D may have no effect on cancer rates compared to controls but may decrease all‐cause mortality (75/1000 vs. 80/1000, respectively; RR, 0.93; 95% CI, 0.88 to 0.98) and may decrease cancer‐related mortality (25/1000 vs. 29/1000, respectively

55 Vitamin D does not Reduce mortally in healthy patients regardless of baseline serum level Benefit cystic fibrosis, chronic pain scores, depression or blood pressure Prevent recurrent adenomas of colon Reduce mortality in colon or any other cancer Improve HgbA1C in diabetics no effect on mortality in healthy patients regardless of dose or baseline 25(OH)D levels vitamin D alone, compared to control, does not prevent hip fractures insufficient evidence of benefit from vitamin D supplementation for the following outcomes: cystic fibrosis (CF), chronic pain scores, depression symptoms or blood pressure vitamin D did not affect hemoglobin A1C (A1C) compared to placebo in patients with type 2 diabetes mellitus (T2DM);20 and one RCT in patients with a history of colorectal adenomas found no benefit of vitamin D, calcium or the combination of both, for prevention of recurrent adenomas.

56 Vitamin D risks Increases risk of nephrolithiasis, hypercalcemia, and gastrointestinal effects

57 PCSK9 Inhibitors Alirocumab (Praluent) Evolocumab (Repatha)
Proprotein Convertase Subtilisin Kexin type 9 Inhibitor! Human monoclonal antibodies inhibit PCSK9 enzyme, reducing degradation of the LDL receptor, lowering LDL‐C\ Alirocumab and evolocumab, FDA approved. Bococizumab - in phase 3 testing. Lowers LDL-cholesterol by ≥ 40% unpublished studies No studies of morbidly or mortality Both are injectable, $13,000/year Oregon P & T Nov 2015; Medical Letter 8/17/2015, 10/12/2015 17 clinical trials, of which 14 are placebo‐controlled. No completed trials have evaluated health outcomes (morbidity or mortality) as primary endpoints. Two ongoing studies, one for evolocumab and one for bococizumab, will evaluate health outcomes as a primary endpoint but are not expected to be completed until None of the 5 completed trials of bococizumab have been published. In addition, no completed or ongoing studies directly compare different PCSK9 inhibitors.

61 Fluad –Influenza Vaccine for Older Adults
Vaccine to counteract lower immune response in elderly Will be available for NEXT season Surrogate endpoint – antibody response Immunogenicity non-inferior to standard vaccine Greater antibody response did not meet superiority criteria More frequent tenderness at injection site SUMMARY: works the same, but hurts more Why bother? FDA ADVISORY COMMITTEE BRIEFING DOCUMENT 9/15/2015; The Medical Letter 1/18/2016 immunogenicity of the new vaccine to be noninferior to that of an unadjuvanted trivalent seasonal influenza vaccine (Agriflu). Compared to Agriflu, Fluad elicited significantly greater antibody responses against all three strains 3 weeks after vaccination, but the differences did not meet the prespecified criteria for superiority. Pain and tenderness at the injection site occurred more frequently with Fluad than with the unadjuvanted vaccine.2

62 Alzheimer’s drugs ACH inhibitors and memantine - modest improvements in cognition, activities of daily living, & behavior None stop or reverse the disease or impact clinical outcomes - mortality, disability, or institutionalization Combination memantine ER + donepezil (Namzaric) Mixed evidence - small improvement in cognition and behavior. Magnitude low, clinical significance is uncertain No improvement in function compared to monotherapy. Generic formulations of both individual products are available Aricept 23 mg increased risk of adverse drug events.

Lorcaserin (Belviq®) selective serotonin 2c agonist Psychiatric effects, headache, dizziness, and nausea Phentermine/Topiramate (Qsymia®) Increased heart rate, paresthesias, and anxiety Naltrexone/Bupropion (Contrave®) Not for patients on Vicodin or other opioids Liraglutide (Saxenda®) glucagon-like peptide-1 agonist for DM-2 that never sold well- injection OSU Drug review Nov 2015, Medical Letter 6/22/2015 Lorcaserin (Belviq®) Lorcaserin is a selective serotonin 2c agonist previously reviewed in the December 2012 newsletter. Lorcaserin was approved based on 3 placebo controlled trials, each about one year in duration. Combined data (n=6139) demonstrated a modest percent reduction in body weight compared to placebo (-4.5 to -5.8% vs to -2.8%, p<0.001) It is still unknown whether this modest reduction is sustained over time and whether use of the drug improves comorbidities associated with obesity. Lorcaserin is also associated with a number of adverse effects and precautions such as adverse psychiatric effects, headache, dizziness, and nausea. Phentermine/Topiramate (Qsymia®) Phentermine/topiramate was also reviewed in the December 2012 newsletter. Drug approval was based on two 56-week placebo-controlled trials that demonstrated a moderate reduction in body weight with both the high (15/92 mg) and low (7.5/46 mg) doses as compared to placebo (-10.9% and -5.1%, respectively vs. -1.6%, p< for all comparisons). It is unknown whether this weight reduction is sustained over time and there is insufficient evidence that the drug improves comorbidities associated with obesity. The agents are also associated with a number of adverse effects and precautions, such increased heart rate, paresthesias, and anxiety. Naltrexone/Bupropion (Contrave®) Bupropion is an antidepressant that inhibits dopamine and norepinephrine reuptake and may promote satiety. Naltrexone augments the appetite suppressant effects of bupropion.5,8 Approval for naltrexone/bupropion was based on four 56-week randomized, placebo-controlled trials (n=4468). Results revealed statistically significant weight loss compared to placebo (- 5.0 to -9.3% vs to -5.1%). The proportion of patients who lost more than 5% and 10% of body weight with naltrexone/bupropion was significantly higher than with placebo (52% and 28%, respectively, vs. 24% and 10% with placebo). Liraglutide (Saxenda®) Liraglutide is an injectable glucagon-like peptide-1 agonist approved for T2DM that can promote satiety. The FDA approved liraglutide for weight loss based on three 56-week randomized, placebo- and active-controlled trials with up to 2 years of follow-up. Data from these 3 trials (n=4999) demonstrated statistically significant weight loss compared to placebo or orlistat (-6 to -8% vs to -2.9%, respectively). The proportion of patients who lost more than 5% and 10% of body weight with liraglutide was significantly higher than with placebo or orlistat (63-73% and 26-27% respectively with liraglutide, vs % and 6-11% with placebo and 44% and 14% with orlistat) Not surprisingly, liraglutide delayed the diagnosis of T2DM in nondiabetics and reduced the onset of pre-diabetes versus placebo at week 56 (30.8% vs. 67.3%; p<0.001).

“Pill to prevent strokes also prevents diabetes, study shows” The Oregonian 2/22/2016 3876 patients, non-diabetic, with insulin resistance, recent new CVA or TIA. Ave age 63.5, 65% male, 85% white Exclude: CHF, liver dz, anemia, dependent edema Pioglitazone vs placebo, ave. followup 4.8 yrs Standard care for htn, other dz, & stroke prevention (statins, ASA, etc) Primary endpoint: first fatal or non fatal stroke or MI NEJM: 2/22/2016 HOMA-%B is a measure of beta cell activity, not of beta cell health or pathology. HOMA can be used in subjects on insulin secretagogues, but the results need to be interpreted with caution. It should be recognized that HOMA is a measure of basal insulin sensitivity and beta-cell function and, in contrast to clamps, is not intended to give information about the stimulated state. It can be seen from the model that for individuals with normal glucose levels, HOMA solutions might indicate 100% beta-cell function and 100% insulin sensitivity, or, in the case of a thin, fit individual with high sensitivity, 50% beta-cell function and 200% insulin sensitivity. Within the context of reporting both results, these are appropriate solutions—sensitivity is doubled, so the beta-cells are functioning at 50% of normal. However, if the beta-cell data are reported in isolation, one might conclude erroneously that the subject had failing beta-cells, as opposed to appropriately low secretion, because the sensitivity of the body was high.

67 Pioglitazone & stroke prevention
Primary outcome: lower composite & individual rates of stroke & MI BUT: Secondary outcomes: Same rate: acute coronary syndrome Same rate: composite of stroke, MI, or CHF hospitalization Are you confused? You should be… Risks: wt gain> 4.5 kg , edema, fracture

68 Pioglitazone & stroke prevention
Smoke & mirrors Study included only the first event Patients with multiple events - only the first one counted. IE patient had MI, later had stoke, the stroke was not counted. Number w multiple events unknown. Results depend on which order events occurred, not on total incidence of stroke or MI
