After a 15-1 vote by an advisory panel recommending approval of Affymax's
Just be careful in assuming that the panel's solid recommendation means a Food and Drug Administration approval tomorrow is guaranteed. It isn't.
The FDA has gone against its outside advisors before, even when the vote was by a wide margin. Bristol-Myers Squibb
Affymax and partner Takeda asked the FDA to approve peginesatide for patients on dialysis because the drug seems to increase the risk of cardiovascular events in patients not on dialysis. The advisory panel brushed off the data and concentrated on the data in dialysis patients where the side effect wasn't seen, but it's not clear to me that the FDA will do the same.
If peginesatide was the first treatment for anemia or had vastly better efficacy than the current offerings, it would be easy to assume the FDA will ignore safety concerns. But the main advantage of peginesatide over Amgen's
As I said at the outset of this article, I think an approval is more likely than not, but figuring out how much weight investors should give to the "not" is difficult, because it's hard to read what the FDA is thinking. Based on the option prices, it doesn't look as if investors are all that worried, but that means there isn't a tremendous upside in the stock, either. Don't expect an instant double after an approval.
I can't see much reason for buying Affymax now unless you're buying it as a long-term purchase, and then, given the unknowns, waiting until its de-risked post-approval might be the best move for some or all of your investment.
