The Allegations: Robbins LLP is Investigating Allegations that Aquestive Therapeutics, Inc. (AQST) Misled Investors Regarding Approval of Anaphylm

According to the complaint, during the class period, defendants created the false impression that Aquestive was on track to receive approval for the Company’s New Drug Application (NDA) for Anaphylm by the January 31, 2026 Prescription Drug User Fee Act (PDUFA) date. In contrast, the FDA identified deficiencies with Aquestive’s NDA for Anaphylm precluding labeling discussions and post-marketing commitments. For the FDA to grant approval for any NDA, any deficiencies must be remedied, therefore the launch of Anaphylm was delayed, indicating that Aquestive failed to obtain approval for Anaphylm by the PDUFA date.

Plaintiff alleges that on January 9, 2026, Aquestive announced that the Company was in receipt of a letter from the FDA identifying deficiencies that precluded labeling discussions for Anaphylm. Moreover, Aquestive revealed that the letter from the FDA confirmed that the Agency’s review of Anaphylm NDA was ongoing and no final decision had been made, which effectively delayed the approval of Anaphylm well beyond the January 31, 2026 PDUFA date. On this news, the price of Aquestive’s common stock declined over 37%, from a closing market price of $6.21 per share on January 8, 2026, to $3.91 per share on January 9, 2026.
