17 BackgroundAcute heart failure is a major health problem responsible for several million hospitalizations worldwide each year.Standard therapy has not changed since 1970s and includes diuretics and variable use of vasodilators or inotropes.In 2001, nesiritide was approved by the FDA to reduce PCWP and improve dyspnea, based on efficacy at 3 hrs.However, in 2005 two meta-analyses raised concerns regarding the risks of mortality and renal injury.Subsequently, an independent panel* was convened by Scios Inc and recommended that a clinical trial be conducted to definitively answer the question of nesiritide’s safety and efficacy.
18 Co-Primary objectives To assess whether nesiritide vs placebo, in addition to standard care provides:Reduction in rate of HF rehospitalization or all-cause mortality through Day 30Significant improvement in self-assessed dyspnea at 6 or 24 hrs using 7-point Likert scale604020% SubjectsMarkedly BetterMinimally WorseModerately BetterModerately WorseMinimally BetterMarkedly WorseNo Change
19 Dyspnea relief at 6 and 24 hrs All-cause mortality at 180 days Study design and drug proceduresNesiritideAcute HF < 24 hrs from IV RX24–168 hrs RxPlaceboCo-primary endpoint:Dyspnea relief at 6 and 24 hrsCo-primaryendpoint:30-day death orHF rehospAll-cause mortality at 180 daysDouble – blind placebo controlledIV bolus (loading dose) of 2 µg/kg nesiritide or placeboInvestigator’s discretion for bolusFollowed by continuous IV infusion of nesiritide 0.01 µg/kg/min or placebo for up to 7 daysUsual care per investigators including diuretics and/or other therapies as neededDuration of treatment per investigator based on clinical improvement

24 ConclusionsNesiritide did not reduce the rate of recurrent heart failure hospitalization or death at 30 days.Nesiritide reduced dyspnea to a modest degree, consistent with previous findings but did not meet pre-specified protocol criteria for statistical significance at 6 and 24 hours.Nesiritide did not affect 30-day all cause mortality nor did it worsen renal function as had been suggested by prior meta-analyses of smaller studies.

HD, high-dose; SD, standard dose
31 GRAVITAS: SummaryCompared with standard-dose therapy, high-dose clopidogrel achieved a modest pharmacodynamic effect in patients with high residual reactivity.In patients with high residual reactivity measured after PCI, 6-months of high-dose clopidogrel did not reduce the rate of cardiovascular death, non- fatal MI, or stent thrombosis and did not increase GUSTO severe or moderate bleeding.In summary,

45 Background: CETP inhibition Cholesteryl ester transfer protein (CETP) is a plasma protein that catalyzes the transfer of CE from HDL to apoB-containing lipoproteins (VLDL and LDL-C) in exchange for Trig.LDL / VLDLLDL-RCESR-B1LiverX inhibitionCETPFCCholesteryl ester transfer protein (CETP) is a plasma protein that catalyzes the transfer of CE from HDL to apoB-containing lipoproteins (VLDL and LDL-C)in exchange for triglycerides that are transferred in the reverse direction.CETP inhibitors increase HDL-C and some also lower LDL-C, and therefore have the potential to reduce coronary events.HDL picks up free cholesterol (FC) from extrahepatic tissues.HDL FC is subsequently esterified by LCAT to form cholesteryl esters (CE)The HDL CE may then be delivered to the liver by either of two pathways:1. A direct pathway following binding of HDL to hepatic SR-B12. An indirect pathway involving the CETP-mediated transfer of CE from HDL to VLDL and LDL with subsequent delivery to the liver following binding of LDL to the LDL receptor."After click:Inhibition of CETP prevents the transfer of CE from HDL to the VLDL/LDL fractions and results in an increase in concentration of HDL-C and a decrease in the cholesterol content of the VLDL/LDL.CEHDLLCATBileFree Cholesterol (FC) in Extrahepatic tissuesFC45
