Real World Study on the Use of Cemiplimab in Adult Patients in UK

Completed
Conditions
Cutaneous Squamous Cell Carcinoma
Interventions
Other: No intervention
Registration Number
NCT05493826
Lead Sponsor
Sanofi
Brief Summary

The primary objective is to describe the real-world clinical effectiveness of cemiplimab in patients with locally advanced cutaneous squamous cell carcinoma (laCSCC) or metastatic cutaneous squamous cell carcinoma (mCSCC) treated in routine clinical practice.

Detailed Description

Patients initiating treatment with cemiplimab in the UK between 2nd July 2019 and 30th November 2020, will be followed for a minimum of 12 and a maximum of 36 months from initiation of cemiplimab.
