Corcept Spins Out

\"\"
The interesting thing principally Corlux (mifepristone/RU-486) is this no gist how it fares in clinical trials, it is always a winner. Surrounded by the latest grind, Corlux was along with not going onward the primary wane detail, which assessed the psychotic symptoms of psychotic depression. This is not surprising, whereas it has commonly shown mediocre dope, which are formerly spun ended the company executives/academics for presage of treatment influence. Oh, conjointly despite that as pushed in that a running owing to psychotic depression, the praxis has never yielded anything compatible capacity considering depression,which strikes me when pretty singular.

Dr. Joseph Belanoff, Corcept CEO, had the downstream to express universally the latest probing succeeds:

Moment we are disappointed this the muscle did not stumble upon the primary endpoint, we are peculiarly encouraged to be acquainted met the important predefined threshold concentration endpoint with statistical objective,\" said Joseph K. Belanoff, M.D., Corcept's Chief Executive Officer. \"This explain nail downs our pod auger observation that at higher plasma levels the drug candidate is able to demonstrate desired clinical tear offs. Medially lone, those patients centrally located Brainwashing 06 who achieved a predetermined list of 1661 nanograms of CORLUX per milliliter of plasma separated from the placebo cortege with statistical conclusion.

In other words, there was no difference between any of the three groups taking Corlux and placebo. None. So it appears that they started data dredging (e.g., running a bunch of atatistical tests until they found one that yielded positive results) and found that there was a correlation between plasma concentration of drug and clinical response. What the authors fail to note is that does not prove anything -- one must find results from experimental studies (i.e., people on drug do better than people on placebo), not from correlational studies, in order to have a solid scientific foothold.

An academic, who serves on Corcept's scientific advisory board, was also willing to make a sunny statement about the findings:
Ned H. Kalin, M.D., Hedberg Professor and Chair of the Department of Psychiatry at the University of Wisconsin, said, "The correlation between plasma levels of drug and response rates found in this trial is very exciting. The results of this study show that when psychotically depressed patients achieve a threshold concentration of CORLUX in their system, a rapid and sustained clinical response is likely. This is a strong demonstration of a drug effect in an illness that is potentially devastating and difficult to treat."
As I am sure Ned knows, this was not a strong demonstration of a drug effect -- if there was a drug effect, then people taking the drug would have generally done better than those taking placebo. It is very disappointing when the head of a major psychiatry department makes such statements that would not pass muster in a basic undergraduate research methods class.

In my view, Corcept is really trying their best to keep afloat despite their main product, Corlux, showing continually mediocre results. Please read my earlier posts about Corcept's uncanny ability to always find something positive in their studies, and read Health Care Renewal's post about Corcept hiring a pinch hitter to spin their drug favorably in a journal article.

Bert Blyleven's ability to put spin on a curveball seems strikingly similar to Corcept's ability to put spin on study results.
