Neoadjuvant Nivolumab and Relatlimab in Cutaneous Squamous Cell Carcinoma

Официальное название

A Phase 2, Open Label, Single Arm, Clinical Trial of Neoadjuvant Nivolumab and Relatlimab in Stage II To IV (M0) Resectable Cutaneous Squamous Cell Carcinoma

Обзор

The goal of this study is to test neoadjuvant therapy with the dual inhibition of Programmed cell death protein 1 (PD-1) and lymphocyte activation gene 3 (LAG-3) immune checkpoint pathways in a cohort of treatment-naïve, resectable stage II to IV cutaneous squamous cell carcinoma on the pathological response rate (pCR) and recurrence-free survival.

Подробное описание

This is a phase 2, open label, single cohort, single centre, clinical trial of neoadjuvant immunotherapy with dual inhibition of PD-1 and LAG-3 immune checkpoint pathways. The hypothesis is that neoadjuvant therapy produces a higher pathological response rate (pCR) and a longer recurrence-free survival in a cohort of treatment-naïve patients with resectable stage II to IV (M0) cutaneous squamous cell carcinoma compared to neoadjuvant cemiplimab monotherapy in Checkmate 358 (n=123, NCT04154943 , historical control).

• Препарат Nivolumab 240 mg / Relatlimab 80 mg in a fixed dose combination

• Women of childbearing potential must have a negative serum pregnancy test within 24 hours of the first dose of study treatment or within 72 hours if this is not feasible. Effective contraception should be used for the duration of study treatment and for 5 half-lives (or 5 months) after the last dose. Egg donation (ova, oocytes) should be avoided for the same period. There are no partner-pregnancy or sperm donation avoidance requirements for male patients.
