Attention Biotech Investors: Mark Your Calendar For November PDUFA Dates

The loaded Prescription Drug User Fee Act (PDUFA) calendar for October produced mixed outcomes.

PDUFA dates are key binary events for biotech stocks that can move the needle in a big way. These are the dates by which the Food and Drug Administration is required to announce its decision regarding approvability/non-approvability of drugs.

ChemoCentryx, Inc.'s CCXI avacopan was the only new molecular entity approved during the month. NMEs are new drug products containing an active ingredient that is marketed for the first time in the U.S. Avacopan, which is to go by the brand name Tavneos, has been approved for treating small blood vessel damage.

Also approved in the month were an application seeking label expansion for Gilead Sciences, Inc.'s GILD CAR T-cell therapy Tecartus for use in advanced lymphoblastic leukemia and Oyster Point Pharma, Inc.'s OYST OC-01 (varenicline) nasal spray for treating dry eye disease.

Among the disappointments were Omeros Corporation's OMER narsoplimab as a treatment option for hematopoietic stem cell transplant-associated thrombotic microangiopathy, Eyenovia, Inc.'s EYEN MydCombi for use as a pupil dilation agent for eye examination and United Therapeutics Corporation's UTHR Tyvaso DPI (inhaled treprostinil) for pulmonary arterial hypertension.

Here are the key PDUFA catalysts for November.
