Summary
The aim of this clinical study is to find out how well Patidegib Gel 2% works in preventing new basal cell carcinomas (BCCs) developing on the face of adults with Gorlin syndrome, and how safe Patidegib Gel 2% is to use. Participants will apply either Patidegib Gel 2% or a Vehicle Gel (with no active drug substance) to their face twice a day for a year (12 months).
