Rare Is Everywhere.
Let’s Treat It.
Building the leading therapeutics company focused on rare genetic skin diseases with no approved therapies.
Palvella (pɑlʋelːɑ)
: a Finnish word meaning “serve”
Palvella Therapeutics is driven by a singular goal: to help every individual suffering from rare genetic skin diseases find a treatment. Founded in 2015, Palvella’s team of passionate industry leaders is dedicated to developing new treatments for patients with rare diseases with no FDA‑approved therapies.
A Visible Need
1 in 10 Americans have a rare disease.1
Genetic skin diseases are visible, often debilitating, and most lack even a single FDA-approved therapy. Among nearly 600 rare dermatologic diseases, less than 2 percent currently have an FDA-approved therapy.
Our Platform:
QTORIN™
Developing targeted topical treatments for certain rare skin diseases is hindered by technical challenges including achieving therapeutic drug concentrations and chemical stability while minimizing system absorption of the drug—issues we’re addressing with Palvella’s QTORIN™ platform.
Since its invention in 2017, the QTORIN™ platform has undergone several years of research and investment, emerging as a new, revolutionary drug delivery platform. Applied topically rather than taken orally, QTORIN™ has the power to transform the current treatment landscape—and transform lives in the process.
Our Programs
QTORIN rapamycin, Palvella’s lead product candidate, is a novel, patented 3.9% rapamycin anhydrous gel, which aims to harness the potential therapeutic benefits of rapamycin, a mammalian target of rapamycin (mTOR) inhibitor.
QTORIN rapamycin is currently in development for the treatment of microcystic lymphatic malformations (Phase 3 SELVA study), cutaneous venous malformations (Phase 2 study), and other serious, functionally debilitating skin diseases driven by the overactivation of the mTOR pathway.
