PD-1 in Patients With Advanced Basal Cell Carcinoma Who Experienced Progression of Disease on Hedgehog Pathway Inhibitor Therapy, or Were Intolerant of Prior Hedgehog Pathway Inhibitor Therapy

The primary objective is to estimate the overall response rate (ORR) for metastatic Basal Cell Carcinoma (BCC) (group 1) and for unresectable locally advanced BCC (group 2) when treated with REGN2810 as a monotherapy

Inclusion Criteria

• Confirmed diagnosis of invasive BCC
• Progression of disease on hedgehog inhibitor (HHI) therapy or intolerance of prior HHI therapy
• At least 1 measurable lesion
• ≥18 years of age
• Hepatic function, renal function, bone marrow function in defined lab-value-ranges
• Anticipated life expectancy >12 weeks
• Consent to provide archived tumor biopsy material (all patients)
• Group 2: consent to undergo research biopsies
• Group 2: must not be a candidate for radiation therapy or surgery
• Comply with study procedures and site visits
• Sign Subject Information Sheet and Informed Consent Form

Exclusion Criteria

• Ongoing or recent significant autoimmune disease
• Prior treatment with specific pathway-blockers (PD-1/PD-L1)
• Prior treatment with immune-modulating agents within 28 days before REGN2810
• Untreated brain metastasis that may be considered active
• Immunosuppressive corticosteroid doses (>10mg prednisone) within 28 days prior to treatment with REGN2810
• Active infections requiring therapy, including HIV, hepatitis
• Pneumonitis within the last 5 years
• Cancer treatment other than radiation therapy, including investigational or standard of care, within 30 days prior to treatment with REGN2810
• Documented allergic reactions or similar to antibody treatments
• Concurrent malignancies other than BCC, other than those with negligible risk of metastases or death
• Any acute or chronic psychiatric problems
• Having received a solid organ transplantation
• Inability to undergo contrast radiological assessments
• Breastfeeding, pregnant, women of childbearing potential not using contraception
