The objectives of the study are:
- To describe the effectiveness of cemiplimab 350 mg administered every 3 weeks (Q3W) for treatment of patients with advanced cutaneous squamous cell carcinoma (CSCC) and patients with advanced basal cell carcinoma (BCC) in real-world clinical settings
- To evaluate the safety of cemiplimab based on incidence of treatment related immune-related adverse events (irAEs), infusion related reactions (IRRs), and treatment related serious adverse reactions (TSARs) in patients with advanced CSCC and patients with advanced BCC receiving cemiplimab treatment in real world clinical settings
- To describe patient experience, including patient reported quality of life (QOL) and functional status, and clinician reported performance status in a real-world setting for patients with advanced CSCC and patients with advanced BCC
- To describe baseline characteristics that could potentially be associated with health-related outcomes for patients with advanced CSCC and patients with advanced BCC undergoing treatment with cemiplimab
- To describe patients who receive cemiplimab as treatment for CSCC or BCC in a real-world setting
- To describe real-world use patterns of cemiplimab for CSCC and BCC
- To investigate the long-term effects and effectiveness of cemiplimab in patients with advanced CSCC or advanced BCC
- To describe the effectiveness of cemiplimab in immunosuppressed and immunocompetent patients with advanced CSCC or advanced BCC, regardless of etiology, per available data
- To describe the effectiveness of cemiplimab after prior exposure to radiation therapy for CSCC per available data
- To describe the effectiveness of cemiplimab as a first-line (1L) or later systemic treatment in patients with advanced CSCC, regardless of etiology, per available data
- To describe the effectiveness of cemiplimab in patients with advanced BCC based on treatment patterns (reason for discontinuation, treatment exposure, etc) of prior HHI usage

- Drug: cemiplimab
No investigational agents will be provided to enrolled patients by the sponsor as part of this study. Patients will have recently initiated or be planning to initiate treatment with commercially available cemiplimab for advanced CSCC or advanced BCC in a real-world setting according to respective label indications. In addition to cemiplimab, patients may receive other therapies as deemed necessary by their physicians for the treatment of CSCC or BCC or comorbid conditions.Other Names:
