Attention Biotech Investors: Mark Your Calendar For These August PDUFA Dates

Biotech stocks had a fairly decent run up in July after a nearly flat performance in June. The iShares NASDAQ Biotechnology Index (ETF) IBB is up about 5 percent.

As the earnings season kicks into high gear and amid several other catalysts, August is likely to be an action-packed month. Here are some key PDUFA action dates a biotech investor should stay focused on.

Pain Therapeutics Looks For Alleviation Of Pain Inflicted By Negative FDA Panel Vote

Company: DURECT Corporation DRRX and Pain Therapeutics, Inc. PTIE
Type of Application: NDA
Candidate: Remoxy
Indication: severe pain
Date: August 7

Pain Therapeutics has licensed Remoxy, an abuse-deterrent extended release capsule formulation of oxycodone, from DURECT. Pain said in mid-February it resubmitted the NDA for FDA review. The previous application was issued a complete response letter in Sept. 2016. Remoxy is indicated to treat severe pain.

Meanwhile, in an adverse development, a FDA panel that met in late June to discuss the NDA voted 14 to 3 against approval of Remoxy for managing pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

The stock, which shed about 71 percent following the FDA panel vote, hasn't recovered.
