Palvella Therapeutics Chief Scientific Officer Jeff Martini, Ph.D. Selected to Present at Upcoming FDA Public Workshop on Drug Repurposing

Hybrid public meeting on August 5th will explore approaches to selecting and prioritizing promising FDA-approved drugs for repurposing, with the potential to accelerate patient access to effective therapies for significant unmet medical needs

Dr. Martini to discuss evidence frameworks and regulatory approaches for advancing repurposed therapies for patients with serious, rare diseases

Meeting builds on FDA’s May 2026 drug repurposing initiative focused on advancing new uses for approved medicines, particularly in chronic or rare diseases with significant unmet medical needs

WAYNE, Pa., July 30, 2026 (GLOBE NEWSWIRE) -- Palvella Therapeutics, Inc. (Palvella or the “Company”) (Nasdaq: PVLA), a clinical-stage biopharmaceutical company focused on developing and commercializing novel therapies for serious, rare skin diseases and vascular malformations for which there are no U.S. Food and Drug Administration (FDA)-approved therapies, announced today that Jeffrey Martini, Ph.D., Chief Scientific Officer of Palvella, has been selected to provide public comment at Drug Repurposing: Considerations for Selection Criteria and Prioritization, an FDA public meeting to be held on August 5, 2026, in Washington, D.C.

“As pioneering research in rare diseases uncovers genetic drivers and causal biology, it can reveal opportunities to repurpose medicines as targeted therapies for previously untreatable diseases, building on accumulated scientific knowledge and clinical experience,” said Jeffrey Martini, Ph.D., Chief Scientific Officer of Palvella Therapeutics. “The combination of an established safety profile and emerging evidence from real-world use suggesting potential clinical benefit can provide a strong foundation for accelerating the development of repurposed therapies, particularly in chronic or rare diseases. I am honored to contribute to this important discussion on how scientific and regulatory frameworks can continue to foster innovation and accelerate access to meaningful therapies for patients with significant unmet medical needs.”

The hybrid public meeting, convened by the Reagan-Udall Foundation in collaboration with FDA, builds on the Agency’s broader initiative to identify new therapeutic uses for approved medicines and expand treatment options for patients with significant unmet medical needs. Bringing together representatives from federal agencies, clinicians, researchers, and patient organizations, the meeting will examine approaches for identifying and prioritizing promising repurposing candidates, as well as the evidence standards and regulatory considerations relevant to advancing them efficiently. During the public comment session, Dr. Martini is expected to address one of the meeting's central discussion questions: “What evidence gaps or policy/regulatory barriers most commonly hinder the advancement of promising repurposing opportunities?”

“Jeff’s selection to provide public comment at this important meeting reflects Palvella’s leadership in advancing first-in-disease therapies for serious, rare diseases through a unique approach that leverages well-characterized existing molecules and real-world clinical evidence,” said Wes Kaupinen, Founder and Chief Executive Officer of Palvella Therapeutics. “Recent years have seen growing momentum behind the development of established molecules for new therapeutic indications, particularly in rare diseases, as advances in the understanding of disease biology create opportunities to apply these molecules as on-target therapies that can directly address the causal drivers of disease. Novel, indication-specific formulations of existing molecules can further enhance the overall benefit-risk profile for patients. We appreciate the opportunity to contribute our perspective as FDA continues to advance scientific and regulatory approaches that can help bring meaningful new therapies to patients.”
