Deep medical and patient care experience will help guide the continued expansion of Palvella’s pipeline and QTORIN™ platform

WAYNE, Pa., April 13, 2026 (GLOBE NEWSWIRE) -- (Palvella or “the Company”) (Nasdaq: PVLA), a clinical-stage biopharmaceutical company focused on developing and commercializing novel therapies to treat patients suffering from serious, rare skin diseases and vascular malformations for which there are no U.S. Food and Drug Administration (FDA)-approved therapies, today announced the appointment of John D. Doux, M.D., M.B.A., to its Board of Directors.

“We are honored to welcome John to our Board as we build Palvella toward our vision of becoming the leading rare disease biopharmaceutical company focused on serious skin diseases and vascular malformations with no FDA-approved therapies,” said Wes Kaupinen, Founder and Chief Executive Officer of Palvella Therapeutics. “John is a highly respected dermatologist and investor who has long been a leading, vocal advocate for the development of novel therapies for rare skin diseases. He brings deep compassion and care from years of treating patients with rare diseases, along with a clear understanding of the profound unmet need across these conditions. His perspective will be especially valuable as we continue to expand our pipeline and the QTORIN™ platform.”

Dr. Doux’s longstanding advocacy for advancing novel therapies in rare skin diseases was reflected in his prescient 2015 Journal of Investigative Dermatology editorial, “Barriers and Opportunities: A View across the Developmental Divide,” which articulated that the orphan disease business model had been under-applied in dermatology despite the field’s many serious, underserved rare diseases. In that editorial, Dr. Doux pointed to emerging investment in epidermolysis bullosa as an early signal of what was possible, while making the case that broader application of this model across dermatology could drive transformative therapies for patients and unlock meaningful value creation for the field.

Dr. Doux is a board-certified dermatologist and a Fellow of the American Academy of Dermatology. Since 2004, he has served as an analyst at Palo Alto Investors LP, a physician-led healthcare focused investment firm, where he has been involved in investments in several leading publicly traded companies developing and commercializing novel therapies for serious, rare diseases. Dr. Doux co-founded the Dermatology Summit and the Dermatology Innovation Forum and previously served on the conference's Board of Directors. Dr. Doux serves as a board trustee for Pachyonychia Congenita Project and as a director on the Board of Directors of Kamari Pharma. He has also served on the boards of multiple biotechnology companies, including Ceptaris Therapeutics, which developed VALCHLOR® for cutaneous T-cell lymphoma and was acquired by Actelion. Dr. Doux previously served on Palvella’s Board of Directors from 2019 to 2022. He maintained a clinical practice in medical and surgical dermatology from 1999 to 2016.

“Palvella has demonstrated that a patient-first approach, together with a commitment to pioneering therapies for diseases with no FDA-approved treatments, can build an enduring biopharmaceutical company with the potential to lead in rare skin diseases and vascular malformations,” said Dr. Doux. “By leveraging a reproducible platform-based business model, beginning with QTORIN™ rapamycin, Palvella has the opportunity to deliver meaningful impact for patients while creating long-term value. I look forward to partnering with the management team to help fulfill Palvella’s mission of serving patients and its vision of becoming the leading company in this space.”

Dr. Doux received his B.S. with Distinction and M.D. from Stanford University and conducted early dermatology research as a Howard Hughes Medical Institute Student Fellow in the laboratory of Dr. David T. Woodley. He completed his internship in internal medicine at Brigham and Women’s Hospital and his dermatology residency at Stanford University Medical Center, where he later served as Chief Resident. He also earned an M.B.A. from The Wharton School of the University of Pennsylvania, where he was named a Palmer Scholar.
