Tomorrow's advisory-panel showdown between Genzyme
The debate surrounds the clinical trial that Genzyme ran in hopes of proving that Clolar helps elderly AML patients. The drug is already approved to treat children with acute lymphoblastic leukemia (ALL). This latest trial didn't have a control group of subjects who didn't get the drug, so it's difficult to determine how patients might have fared compared to the 45.5% remission rate for the patients taking Clolar. In 2005, an FDA advisory panel failed to recommend an AML drug from Johnson & Johnson
The company says that the patients wouldn't really have any other treatment options -- and I'm assuming spontaneous remission is much, much rarer than 45% -- but the FDA panel seems to be disappointed that there was no placebo control group, nor a test against chemotherapy, which might have benefited some of the patients.
The problem for Genzyme tomorrow: Even if it convinced a majority of the advisory committee members that there was enough data to prove the drug's success in AML patients, the FDA has the final say. The agency seems set to reject the expansion of Clolar, no matter what the panel votes.
Good luck, Genzyme.
