ATRS Shares Rocked as FDA Finds Deficiencies in XYOSTED NDA

Companies always try and figure out the best time to release news, albeit positive or negative, with respect to market reaction. For bad news, a release after the market close is usually hoped to dampen the blow, but it generally doesn’t matter much. This is the case with Antares Pharma (NASDAQ: ATRS) on Friday following a 5 PM ET release of news on Thursday that the U.S. Food and Drug Administration has some issues with XYOSTED™ (testosterone enanthate), Antares’ injectable testosterone replacement therapy.

The Ewing, New Jersey-based drug maker has a new drug application pending with the FDA for XYOSTED™ with a Prescription Drug User Fee Act (PDUFA) date of October 20, 2017.

Staring down the FDA’s decision, shares of ATRS have been climbing, including hitting a nearly four-year high on Monday at $4.09, in part on the PDUFA date. Antares also said this week (to little fanfare) that it sold worldwide rights to its ZOMAJET™ needle-free auto injector device to Ferring Pharmaceuticals for up to $14.5 million.

Shares are taking a beating in Friday morning trading following Thursday’s news that the FDA found deficiencies with the NDA for XYOSTED™ “that preclude the continuation of the discussion of labeling and postmarketing requirements/commitments at this time.”

The government agency didn’t enlighten Antares as to what the deficiencies exactly were, leaving shareholders in the dark with a marketing decision for XYOSTED™ expected within a week. In September, Antares received labeling comments from the FDA, which it responded to promptly, a reply that the FDA doesn’t appear ready to address just yet, based upon the latest communication.

While this could just be a mild hiccup on the path to commercialization, investors don’t like reading about “deficiencies” in a NDA review or speculating about any potential delays with said application. Showing the dissatisfaction, shares have been clubbed back to $2.30 in morning activity for a loss of 38.3% after touching $2.16, the lowest level for ATRS since February 8.
