Eligibility
Key inclusion criteria
Key

- For Japan only, men and women =21 years old

- Patient with resection of pathologically confirmed CSCC (primary CSCC lesion only, or
primary CSCC with nodal involvement, or CSCC nodal metastasis with known primary CSCC
lesion previously treated within the draining lymph node echelon), with macroscopic
gross resection of all disease

- High risk CSCC, as defined in the protocol

- Completion of curative intent post-operative radiation therapy (RT) within 2 to 10
weeks of randomization

- Eastern Cooperative Oncology Group performance status (ECOG PS) =1

- Adequate hepatic, renal, and bone marrow function as defined in the protocol

Key
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Squamous cell carcinomas (SCCs) arising in non-cutaneous sites as defined in the
protocol

- Concurrent malignancy other than localized CSCC and/or history of malignancy other
than localized CSCC within 3 years of date of randomization as defined in the protocol

- Patients with hematologic malignancies (note: patients with chronic lymphocytic
leukemia (CLL) are not excluded if they have not required systemic therapy for CLL
within 6 months of enrollment)

- Patients with history of distantly metastatic CSCC (visceral or distant nodal), unless
the disease-free interval is at least 3 years (regional nodal involvement of disease
in draining lymph node basin that was resected and radiated prior to enrollment will
not be exclusionary)

- Ongoing or recent (within 5 years of randomization date) 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.

- Has had prior systemic anti-cancer immunotherapy for CSCC

Note: Other protocol defined Inclusion/Exclusion criteria apply

Summary
Brief summary
The primary objective of the study is to compare disease-free survival (DFS) of patients with
high-risk cutaneous squamous cell carcinoma (CSCC) treated with adjuvant cemiplimab, versus
those treated with placebo, after surgery and radiation therapy (RT).

The secondary objectives of the study are:

- To compare the overall survival (OS) of high-risk CSCC patients treated with adjuvant
cemiplimab, versus those treated with placebo, after surgery and RT

- To compare the effect of adjuvant cemiplimab with that of placebo on patients' freedom
from locoregional recurrence (FFLRR) after surgery and RT

- To compare the effect of adjuvant cemiplimab with that of placebo on patients' freedom
from distant recurrence (FFDR) after surgery and RT

- To compare the effect of adjuvant cemiplimab with that of placebo on the cumulative
incidence of second primary CSCC tumors (SPTs) after surgery and RT

- To evaluate the safety of adjuvant cemiplimab and that of placebo in high-risk CSCC
patients after surgery and RT

- To assess cemiplimab pharmacokinetics and immunogenicity in human serum
