QTORINTM rapamycin for PC

QTORINTM rapamycin 3.9% is a novel topical therapy being studied for Pachyonychia Congenita (PC). We expect to begin enrolling a phase 3 study in PC in late 2021.

PC: A Disease of Limited Mobility and Pain

PC is a rare, chronically debilitating and lifelong disease in which mutations of genes responsible for keratin production lead to dysregulated keratinocyte proliferation, increased skin fragility, and impaired skin barrier function on the feet. Affected individuals have difficulty walking, and often require ambulatory aids or crawling.

Palvella estimates that there are 14,000 people with PC diagnosed and treated by Dermatologists and Podiatrists in the US.

There are no FDA approved therapies for PC.

Targeting the Root Cause of PC

The potential for rapamycin in PC was discovered by leading scientists and geneticists in the field of PC research who demonstrated a direct mechanism of action of mTOR inhibitors on translationally repressing the mutant keratin genes which are the root cause of PC.

QTORINTM rapamycin 3.9%  has been awarded Fast Track Designation, FDA Orphan Drug Designation, and EMA orphan drug designation for PC.

The VAPAUS Study

We plan to start the VAPAUS study in the second half of 2021.  The VAPAUS study is a pivotal phase 3 multicenter clinical study evaluating the safety and efficacy of QTORINTM rapamycin 3.9% in adults with moderate to severe pachyonychia congenita. To stay updated on progress or to inquire about participating in studies for Pachyonychia Congenita, please contact PC Project.

Trial Requirements Include:
  • Moderate to Severe PC
  • Adults, Age 18 or Older
  • Able and willing to comply with all protocol-required activities
