The FDA went overdrive in the month of June, deciding on several regulatory applications before the July 4 holiday. There were favorable outcomes as well as disappointments.

Acer Therapeutics Inc (NASDAQ: ACER) went about a freefall, shedding about 79% in a single session after the FDA issued a complete response letter to the NDA for its rare genetic disorder drug.

Merck & Co., Inc. (NYSE: MRK)'s Keytruda snagged two approvals in the month – for head and neck cancer as well as lung cancer.

As the first half of the year winds down, new molecular entity approvals thus far totaled 12 compared to 20 approvals in the same time last year.

PDUFA dates are deadlines for the FDA to review new drugs. The FDA is normally given 10 months to review new drugs. If a drug is selected for priority review, the FDA is allotted six months to review the drug. These time frames begin on the date that an NDA is accepted by the FDA as complete.

Here are the key PDUFA dates to watch in July.
