Summary

This Phase 3 study tests whether a gel containing patidegib can lower the number of new basal cell carcinomas (a type of skin cancer) on the face of adults with Gorlin syndrome. Participants apply the gel or a placebo to their face twice daily for a year. The study will compare how many new cancers appear between the two groups.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Patidegib gel 2%
What this could lead to
If it works, this could provide a topical treatment to reduce the number of new skin cancers on the face for people with Gorlin syndrome.
What could go wrong
This is a relatively small Phase 3 trial (140 people). The gel may not significantly reduce new BCCs compared to placebo, and long-term safety is not yet established.
