Expanded Access Protocol for Cemiplimab in Metastatic or Locally Advanced Cutaneous Squamous Cell Carcinoma

Study Overview
=================
Brief Summary
-----------------
The objective of this program is to provide access to cemiplimab (REGN2810) to patients with metastatic cutaneous squamous cell carcinoma (mCSCC) or locally advanced cutaneous squamous cell carcinoma (laCSCC) who are not candidates for surgery prior to cemiplimab (REGN2810) being commercially available.

Official Title
-----------------
An Open-Label, Expanded Access Protocol of Cemiplimab in Patients With Metastatic or Locally Advanced Cutaneous Squamous Cell Carcinoma Who Are Not Candidates for Surgery

Conditions

* Drug: cemiplimab

Eligibility Criteria
-----------------
Key Inclusion Criteria: Histologically confirmed diagnosis of invasive Cutaneous Squamous Cell Carcinoma (CSCC) Hepatic function: Total bilirubin ≤1.5 x upper limit of normal (ULN; if liver metastases ≤3 x ULN). Transaminases ≤3 x ULN (or ≤5.0 x ULN, if liver metastases) Alkaline phosphatase ≤2.5 x ULN (or ≤5.0 x ULN, if liver or bone metastases) Patients with hepatic metastases: If transaminase levels (AST and/or ALT) are >3 x but ≤5 x ULN, total bilirubin must be ≤1.5 x ULN. If total bilirubin is >1.5 x but ≤3 x ULN, both transaminases (AST and ALT) must be ≤3 x ULN Renal function: serum creatinine ≤1.5 x ULN or estimated creatinine clearance (CrCl) >30 mL/min Bone marrow function: Hemoglobin ≥9.0 g/dL Absolute neutrophil count (ANC) ≥1.5 x 10^9/L Platelet count ≥75 x 10^9/L Patients not candidates for surgery include the examples below, but are not limited to: Metastatic disease (distant or nodal) Recurrence in the same location and curative resection is unlikely Significant local invasion that precludes complete resection Surgery may result in severe disfiguration or dysfunction Other conditions deemed to be contraindicating for surgery Key Exclusion Criteria: Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments, which may suggest risk for immune-related adverse events (irAEs). The following are not exclusionary: vitiligo, childhood asthma that has resolved, type 1 diabetes, residual hypothyroidism that required only hormone replacement, or psoriasis that does not require systemic treatment Prior treatment with other immune modulating agents that was (a) within fewer than 4 weeks (28 days) prior to the first dose of cemiplimab (REGN2810), or (b) associated with immune-mediated adverse events (AEs) that were ≥ Grade 1 within 90 days prior to the first dose of cemiplimab (REGN2810), or (c) associated with toxicity that resulted in discontinuation of the immune-modulating agent Continuous immunosuppressive corticosteroid treatment (doses >10 mg prednisone daily or equivalent) within 2 weeks prior to the first dose of cemiplimab (REGN2810)Note: Patients who require brief course of steroids (eg, as prophylaxis for imaging studies) are not excluded Active uncontrolled infection requiring therapy, including infection with human immunodeficiency virus, or active infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) History of pneumonitis within the last 5 years Note: Other protocol defined Inclusion/Exclusion criteria may apply
