PellePharm Initiates Phase 2 Clinical Trial of Patidegib Topical Gel for People With High Frequency Basal Cell Carcinoma
“There are approximately 35,000 people with HF-BCC in
The randomized, double-blinded, stratified, vehicle-controlled Phase 2 trial is evaluating the safety and efficacy of Patidegib Topical Gel 2% applied twice daily to the face over nine months vs. vehicle gel. The primary endpoint of the study is the number of surgically eligible basal cell carcinoma (nSEB) that develop on the face of participants over the nine-month period. The primary endpoint will be assessed by imaging and tracking of BCCs consistently throughout the study in order to identify nSEBs, consistent with the methods employed in the ongoing Phase 3 study of Patidegib topical gel for people living with Gorlin Syndrome. Approximately 40 participants will be enrolled in the Phase 2 trial.
“People with non-Gorlin HF-BCC are phenotypically similar to people with Gorlin Syndrome with respect to their BCCs, but are not born with a germline PTCH1 mutation. Those with HF-BCC are faced with the challenge of frequent BCC surgeries, which can be debilitating, painful and disfiguring, particularly to the face,” said
PellePharm recently completed enrollment for its Phase 3 clinical trial of Patidegib Topical Gel 2% for people living with Gorlin Syndrome. PellePharm entered into a strategic collaboration with LEO Pharma in
Patidegib Topical Gel, an investigational treatment, is designed to reduce the BCC tumor burden in people living with Gorlin Syndrome and High Frequency BCC (HF-BCC) by blocking the disease at its source within the hedgehog signaling pathway. Patidegib Topical Gel has shown early promise in a Phase 2 clinical study for the mitigation of BCC tumors in Gorlin Syndrome. The topical formulation of Patidegib was developed with a goal of providing the clinical activity previously demonstrated by oral Patidegib in Phase 1 trials and a favorable tolerability profile without the adverse systemic side effects observed with the oral class of hedgehog inhibitors. The topical gel formulation is stable at room temperature for at least two years, potentially making it an option for ongoing, at-home management of Gorlin Syndrome and HF-BCC. PellePharm has received both Orphan Drug Designation and Breakthrough Therapy Designation for Patidegib Topical Gel in Gorlin Syndrome from the
About Gorlin Syndrome
Gorlin Syndrome is a rare, genetic disease characterized by constitutional, heritable mutations in one allele of the tumor suppressor gene encoding PATCHED1 (PTCH1), which acts as the primary inhibitor of the hedgehog signaling pathway. This leads to the formation of multiple basal cell carcinomas (BCCs), often on the face.
About High Frequency Basal Cell Carcinoma (HF-BCC)
HF-BCC, like Gorlin Syndrome, is a rare disease which is characterized by the development of an abnormally high number of basal cell carcinomas (BCCs). Unlike people with Gorlin Syndrome, people with HF-BCC are not born with a germline PTCH1 mutation and do not suffer from the other systemic manifestations of Gorlin Syndrome. The current standard of care for people living with HF-BCC is BCC surgery.
Founded by world leaders in hedgehog pathway signaling, PellePharm, a BridgeBio company, is committed to targeting rare forms of basal cell carcinoma, including Gorlin Syndrome and High Frequency Basal Cell Carcinoma (HF-BCC), at their source. PellePharm’s mission is to improve the quality of life for those suffering from Gorlin Syndrome and HF-BCC by providing an easy-to-use topical gel that could potentially reduce the need for regular, painful and disfiguring surgeries. Patidegib topical gel is a topical formulation of a proprietary hedgehog inhibitor.
