NP137 Clinical and Biological Activities Assessment in Patients With Advanced/Metastatic Solid Tumors Treated by Standard Anti PD-1/PD-L1 Immunotherapies

Summary

This study is a multicenter, open-label, proof-of-concept study aiming to assess the clinical and biological impact of NP137 when added to standard PD-1/PD-L1 blockade therapy in 3 independent cohorts of advanced or metastatic solid tumors with various sensitivity to anti-PD-1/PD-L1: * Cohort 1 \[Stable Disease\]: Patients with a radiological documentation of SD according to RECIST V1.1 criteria following at least 12 weeks under standard anti PD-1/PD-L1 therapy. Note: This treatment arm closed on 27/09/2024 due to non-feasibility. * Cohort 2 \[primary refractory\]: Patients with documented radiological PD or short-term SD (\< 6months) according to RECIST V1.1 but with clinical benefit under PD-1/PD-L1 standard therapy. * Cohort 3 \[secondary refractory\]: Patients with documented radiological PD following an initial Objective Response or long-term SD (i.e. ≥6 months) according to RECIST V1.1, with clinical benefit under standard PD-1/PD-L1.
