What this trial studies

This study investigates the safety and pharmacokinetics of QTORIN rapamycin 3.9% anhydrous gel in adults diagnosed with Pachyonychia Congenita who have specific keratin mutations. It is a multicenter, open-label treatment study that enrolls participants who have previously completed the PALV-05 trial. The focus is on understanding the long-term effects of the gel and how it is processed in the body.

Who should consider this trial

Good fit: Ideal candidates are adults with Pachyonychia Congenita who have completed the PALV-05 study and have specific keratin mutations.

Not a fit: Patients who are pregnant, breastfeeding, or using sirolimus-containing medications will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for managing symptoms of Pachyonychia Congenita.

How similar studies have performed: While this approach is novel for Pachyonychia Congenita, similar studies evaluating topical treatments for genetic skin conditions have shown promise.
