Frequently asked questions about Patidegib

What is patidegib used for?

Patidegib is an investigational topical treatment being developed for Gorlin syndrome, also called basal cell nevus syndrome. It is intended to reduce the disease burden of basal cell carcinomas that develop persistently in adults with this rare inherited condition, including lesions on the face.

How does patidegib work?

Patidegib is a small molecule antagonist of SMO, a protein in the Hedgehog signaling pathway. By blocking SMO, patidegib is designed to inhibit the aberrant Hedgehog pathway signaling that drives basal cell carcinoma development in Gorlin syndrome. It is formulated as a topical gel applied directly to the skin.

Who is developing patidegib?

Patidegib is being developed by Sol-Gel Technologies Ltd., which trades under the ticker SLGL. The company is advancing the topical gel formulation for Gorlin syndrome, also known as basal cell nevus syndrome.

What phase is patidegib in?

Patidegib is in Phase 3 clinical development. It is an investigational therapy and has not been approved by the FDA. Two Phase 3 trials have been completed, and no trials are currently listed as active.

What clinical trials is patidegib in?

Patidegib has been studied in two completed Phase 3 trials. NCT03703310 enrolled 174 patients with basal cell nevus syndrome, and NCT06050122 enrolled 113 adults with Gorlin syndrome across the United States and several European countries. Both were randomized, double-blind, and placebo-controlled.

Is patidegib the same as patidegib topical gel, 2%?

Yes. Patidegib topical gel, 2% is the same investigational product as patidegib, referring to the 2% strength gel formulation used in its clinical trials. Patidegib is also written as patidegib, 2% in some references.
