A Multicenter, Randomized, Double Blind, Vehicle-controlled, Phase 3 Efficacy and Safety Study of Patidegib Gel 2% for the Reduction of Disease Burden of Persistently Developing Basal Cell Carcinomas (BCCs) in Subjects with Gorlin Syndrome

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). The number of new BCCs on the face will be compared between participants who used Patidegib Gel 2% or Vehicle Gel after 12 months.

Detailed Description

This is a global, multicenter, randomized, double-blind, stratified, vehicle-controlled study of the efficacy and safety of Patidegib Gel 2%, applied topically twice daily to the face of adult participants with Gorlin syndrome. Participants will be randomized (1:1) to receive either Patidegib Gel 2% or Vehicle Gel for 12 months. The assignment of participants to the 2 groups will be stratified by sex assigned at birth, age (â‰¥60 or <60 years), and number of facial BCC lesions (10-15, 16-30 or >30) at Baseline. All BCCs at baseline, and any new BCCs which develop during the study, will be photographed and tracked during the study. New BCCs will be confirmed by dermoscopy analysis.
