Alnylam wins its first drug approval
Alnylam Pharmaceuticals announced the landmark FDA approval for its first commercial drug on Friday, but investor concerns about pricing and a conservative decision by the agency on the drug's label threw cold water on the celebration today, causing the biotech's stock to fall 6.6%. The FDA approved Onpattro (patisiran) for treatment of polyneuropathy caused by the rare and potentially fatal disease hereditary transthyretin-mediated (hATTR) amyloidosis.
Alnylam believes that there are 20,000 to 30,000 patients worldwide with the indication the FDA approved, with 10,000 to 15,000 of those in the U.S. However, the disease is underdiagnosed, and there are currently less than 3,000 diagnosed cases in this country. Alnylam set the list price of the treatment at $450,000 per year, or $345,000 after discounts.
Causing some concern among analysts on the call, though, was Alnylam's agreement with payers for value-based pricing. The company will get the full price for patients that respond well to the treatment, but will have several levels of discounts if results are "suboptimal." Alnylam said these discounts are not included in the $345,000 pricing guidance, and it was unwilling to estimate what they would amount to, throwing considerable uncertainty into revenue forecasts.
Furthermore, the company had hoped that trial results showing cardiac benefits could be mentioned on the drug's label, giving it an advantage over competition from Ionis Pharmaceuticals and Pfizer . The FDA disallowed that, saying that Alnylam's clinical results were not sufficient to firmly establish those benefits.
The first U.S. approval of a drug for hATTR amyloidosis was a historic event, but investors weren't quite ready to celebrate until pricing and competitive issues come better into focus.
