Why Clinical Trials Fail. Whence the Low Productivity? Don’t) Blame the Chemists. Castalia, Kinetics, Space. Small Sample Size Paradox. Terra Incognita of Science. What’s in a Name? Don’t) Blame the Chemists. Couple of days ago, I was talking to a medicinal chemist about why drug development productivity might have decreased. I pushed him to explain and here is what he said. 1) good chemists can get you good compounds against any target. But is that the way it should be? Are they doing their job if they ...

Why Clinical Trials Fail. Whence the Low Productivity? Don’t) Blame the Chemists. Castalia, Kinetics, Space. Small Sample Size Paradox. Terra Incognita of Science. What’s in a Name? Whence the Low Productivity? One of the most intractable problems in drug development has been productivity. Now, it is very difficult to discern what factor plays what role in productivity, since there are few controls to compare against. So for the most part, the debates are based on opinions. Yes, their costs have been goi...

Why Clinical Trials Fail. Whence the Low Productivity? Don’t) Blame the Chemists. Castalia, Kinetics, Space. Small Sample Size Paradox. Terra Incognita of Science. What’s in a Name? In 1990, New York City closed 42nd Street in observance of Earth Day (1). The 42nd Street is a major thoroughfare, and its closure was expected by many to be a disaster. Manhattan’s traffic is bad enough on an ordinary day: surely the closure of a major artery could only make it worse. In other cases, it is because we mistake...

You can’t just sign a check and expect the CRO to deliver what you want. I guarantee that if you do that they will not deliver. They are not mind readers. And they don’t always have their economic incentives aligned with yours. One Response to “Managing CROs 101”. March 1, 2014 at 2:10 am. This assessment is spot-on and a gre...

Small Sample Size Paradox. Small Sample Size Illusion is an illusion that will eventually make it into my next iteration of the cognitive optical illusions slide set, but in the meanwhile, I am posting it on the blog. So how does this apply to clinical trial interpretation? Often in a journal article, you will see a graph lik...

Castalia, Kinetics, Space. In a novel,. But unfortunately, their accomplishments are irrelevant to the real world and they accomplish nothing. In addition to tearing apart the models used in drug development, he made a couple of important points. The first is that animal models can be great at deciphering normal physiolog...
