The string of failures– for HDL therapies in general and for niacin in particular– continues unabated.

In the wake of HPS2-THRIVE many have argued that there is no longer any reason to prescribe niacin. William Boden, the lead investigator of AIM-HIGH and COURAGE, thinks there were enough flaws in the design of the niacin trials to justify the cautious use of niacin in certain circumstances. Says Boden:
“There is evidence of clinical outcome improvement (i.e., CHD death/MI reduction) from VA-HIT for gemfibrozil; there is similar clinical outcome improvement for niacin from the Coronary Drug Project. Numerous studies show niacin’s benefit on surrogate outcome measures (i.e., quantitative coronary angiography, IVUS, cIMT, etc.). What more evidence do you need?”
” I have not given up on niacin.”
Harlan Krumholz disagrees:
“We have to face the facts about the trials. They have failed to be supportive, and despite concerns about their flaws, they were developed by some of the best minds in our profession (including yours) and had millions of dollars devoted to them. I just feel that we cannot justify millions of people being prescribed a drug that has failed in two recent, large, prominent trials, which actually had signals of harm…”
