About PVLA
Palvella Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on developing and commercializing therapies to treat patients suffering from serious, rare genetic skin diseases for which there are no FDA-approved therapies. The Company is developing a pipeline of product candidates based on its patented QTORIN platform, with an initial focus on serious, rare genetic skin diseases, many of which are lifelong in nature. Its QTORIN product candidates are developed to accommodate the cargo at high concentrations in order to drive sufficient drug to its target deep in the epidermis and dermis. The Company's lead product candidate, QTORIN 3.9% rapamycin anhydrous gel (QTORIN rapamycin), is being evaluated in the Phase III SELVA clinical trial in microcystic lymphatic malformations and the Phase II TOIVA clinical trial in cutaneous venous malformations.

Palvella Publishes Systematic Review on Statins for Porokeratosis
- Publication of Findings: Palvella Therapeutics has published a systematic review in Clinical and Experimental Dermatology, synthesizing 24 studies involving 95 patients treated with off-label topical statins for porokeratosis, highlighting the clinical potential and scientific rationale for this therapeutic approach.
- Significant Clinical Need: The review underscores the lack of FDA-approved therapies for porokeratosis, which severely impacts patients' quality of life, positioning Palvella's QTORIN™ pitavastatin as a potential solution, with Phase 2 trials anticipated in the second half of 2026.
- Efficacy Observations: The systematic review indicates that the majority of patients experienced at least partial clinical benefits, with symptom relief and lesion size reduction observed across a broad age range from 2 to 85 years, emphasizing the potential advantages of topical application.
- Future Research Directions: The review calls for controlled clinical trials using standardized endpoints to robustly evaluate the safety and efficacy of statins, aiming to provide more effective treatment options for porokeratosis patients and advance scientific understanding in this area.
