Palvella Therapeutics, Inc. has announced a major milestone in its drug development journey. On October 28, 2026, the company revealed that the U.S. Food and Drug Administration (FDA) has accepted for filing and granted Priority Review to its New Drug Application (NDA) for QTORIN™ 3.9% rapamycin anhydrous gel.

This development is crucial for Palvella as it seeks to bring its innovative treatment to market. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of February 28, 2027, which indicates when the agency will make a decision on the approval of the drug. The Priority Review designation is granted to drugs that may offer significant improvements in safety or effectiveness over existing treatments, highlighting the potential impact of QTORIN™ in the pharmaceutical preparations sector.
