Brief summary
This study is researching an experimental drug called cemiplimab. The study is focused on Cutaneous Squamous Cell Carcinoma (CSCC) and Basal Cell Carcinoma (BCC). The aim of the study is to evaluate the safety and tolerability (how your body reacts to the drug) of cemiplimab (also known as REGN2810). The first part of the study tested several different doses of cemiplimab given weekly for 12 weeks. The study is also looking at several other research questions, including: * What side effects may happen from taking the study drug * To see effect of cemiplimab on the tumor * How much study drug is in the blood at different times
Interventions
Each patient will receive intralesional injections of cemiplimab every week (QW), or at less frequent dosing into the lesion at the assigned dose level for 3-12 weeks prior to scheduled surgery

Study design
Intervention model description
Cohorts A, B, D and H will enroll sequentially (not randomized). Cohort C and I for BCC will enroll in parallel with, and independently of, Cohorts A, B, D and H for CSCC patients
Eligibility
Inclusion criteria
Key Inclusion Criteria 1. Dose Escalation: History of recurrent resectable CSCC or BCC (Cohort C and I only) that satisfies conditions as defined in the protocol 2. Patients must have measurable disease in the index lesion, defined as 1-2 cm in the longest diameter 3. Eastern Cooperative Oncology Group (ECOG) performance status ≤1 Key
Exclusion criteria
1. Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments, which may suggest risk for immune-mediated adverse events (imAEs) 2. Prior treatment with an agent that blocks the programmed cell death 1 (PD-1)/ programmed cell death 1 ligand (PD-L1) pathway. 3. Prior treatment with other systemic immune modulating agent as defined in the protocol 4. M1 or N1, N2 (a, b, or c), or N3 CSCC or BCC. Patients with history of metastatic CSCC (distant or nodal), or metastatic BCC (distant or nodal) are excluded unless the disease-free interval is at least 3 years 5. Concurrent malignancies, other than those with negligible risk of metastasis or death. Patients with hematologic malignancies, including chronic lymphocytic leukemia (CLL), are excluded. 6. Patients with a history of solid organ transplant 7. Has received a Coronavirus induced disease of 2019 (COVID-19) vaccination (initial series and booster) within 1 week of planned start of study medication Note: Other protocol defined Inclusion/

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objective response rate (ORR) of index lesion | At baseline and at Week 13 | Determined by the investigator using the modified World Health Organization (WHO) criteria |
