Data on muraglitazar is relatively sparse due to the brief introduction and subsequent abandonment of this agent. One double-blind randomized clinical trial[2] comparing muraglitazar and pioglitazone found that the effects of the former were favourable in terms of HDL-C increase, decrease in total cholesterol, apolipoprotein B, triglycerides and a greater reduction in HbA1c (p <0.0001 for all comparisons). However, the muraglitazar group had a higher all-cause mortality, greater incidence of edema and heart failure and more weight gain compared to the pioglitazone group. A meta-analysis of the phase II and III clinical trials of muraglitazar revealed that it was associated with a greater incidence of myocardial infarction, stroke, transient ischemic attacks and congestive heart failure (CHF) when compared to placebo or pioglitazone.[4]
By calling attention to adverse events made public through the FDA advisory committee process, Dr Nissen came upon a mechanism to steer FDA from the outside.[citation needed] This mechanism came to fruition with rosiglitazone (Avandia) and led to FDA requiring demonstration of cardiac safety for new drugs to treat type 2 diabetes.[citation needed] This process is described by Dr Robert Misbin in INSULIN-History from an FDA Insider, published June 1, 2020 on Amazon.[promotion?]
