Drug approvals - more good news from Pharma

More than two years ago I blogged about an upturn in drug approvals. Although, there were concerns this might be a temporary fluke, so far the trend has continued. Let's just hope that drug prices do not rise all that much in the future, since 2014 has been the year of biologics and orphan drugs, not exactly known to be cheap. (Note: In 2013, 7 out of 10 best-selling drugs were biologics.)

Drug approvals (New Molecular Entity + Biologics, ref. 1, 2) increased from the low 20s from the years past.
2007: <20
2012: 39
2013: 27
2014: 41
2015: 45 (edit: updated data)
2016: 22 (edit: updated data)

What's the link to biogerontology?
First of all, the pace of pharma research indicates whether we are capable of addressing challenging diseases or if they are intractable for some reason. Second, aging is one of the most challenging diseases or disease-causing conditions and the first, primitive drugs to treat it may well be small molecules. Since development of these anti-aging drugs will require the help of pharma at some point, it's good to see the business thriving again.

Aspirin and Ethics - a brief reflection

When I was reading current literature on Aspirin I found this gem (emphasis mine):

"Once-daily, low-dose aspirin did not significantly reduce the risk of the composite outcome of cardiovascular death, nonfatal stroke, and nonfatal myocardial infarction among Japanese patients 60 years or older with atherosclerotic risk factors...
[Hence] The [JPPP] study was terminated early by the data monitoring committee after a median follow-up of 5.02 years (interquartile range, 4.55–5.33) based on likely futility...We plan to conduct further analyses to establish whether aspirin had beneficial effects in particular subgroups of patients or if there were beneficial effects with respect to cancer prevention."

Is this the ethics committee-equivalent of first shoot, then ask questions? Why would you kill the study for futility before conducting a full analysis including cancer? I know that there are confounding issues if cancer was only a secondary endpoint, but at some point something must have gone ridiculously wrong, be it initial study design or the decision by the ethics committee. Perhaps, we are just dealing with sloppy writing, the monitoring committee knowing that cancer was unchanged, and the authors hoping that a signal will emerge now or in the future. Something isn't quite right here.

Either way, it'd be a travesty if there turns out to be a signal, yet the trial (n~14 000) was stopped precociously.
