COLUMBIA, Md. ( TheStreet) -- Osiris Therapeutics (OSIR) "disappeared" important data when the company announced results Monday from a mid-stage study of its stem cell therapy Prochymal in heart attack patients.
Naturally, Osiris didn't come out and tell investors that it was issuing a misleading press release on the Prochymal heart attack study. Instead, the company claimed the study was a success. That's not true. Figuring out Osiris' deception wasn't that difficult if you know how to parse the language of clinical trial results and look at independent sources of information for the truth.
Ride along with me as I pick apart Osiris' statements regarding the Prochymal heart attack study. Interpreting clinical trial results with a skeptical eye is a crucial tool for all biotech investors, so apply these skills universally whenever a drug or biotech company tries to convince you that its drug works. Hopefully, you'll find most companies are telling the truth, but sadly and too often, bullish pronouncements about boffo clinical trial data are just spin jobs ginned up to plaster over problems and bad data.
Here's what Osiris issued Monday:Osiris Therapeutics, Inc. announced today interim one-year results from its groundbreaking clinical trial evaluating Prochymal (remestemcel-L) for the treatment of patients experiencing first-time acute myocardial infarction. The trial is the largest study of allogeneic or "off-the-shelf" stem cells ever conducted in heart attack patients. A total of 220 patients were given a single infusion of either Prochymal or placebo through a standard intravenous line within seven days of an acute heart attack. Not much to quibble with here except it's helpful to know that Osiris enrolled the first heart attack patient to this study in April 2009, so it took more than three years to complete and report "interim" results.
