Eftilagimod Alpha (a Soluble LAG-3 Protein) Combined With Pembrolizumab in Second-Line Metastatic NSCLC Refractory to Anti-Programmed Cell Death Protein 1/Programmed Death-Ligand 1-Based Therapy: Final Results from a Phase 2 Study.

ABSTRACT:

Introduction

Eftilagimod alpha (efti), a soluble lymphocyte activation gene-3 protein, triggers antigen-presenting cell and T-cell (CD4⁺ and CD8⁺) activation and helps overcome resistance to programmed cell death protein 1 or programmed cell death-ligand 1 (PD-(L)1) inhibitors. We assessed efti plus pembrolizumab in second-line anti-PD-(L)1-refractory metastatic patients with NSCLC.

Methods

After confirmed progression on anti-PD-(L)1-based first-line therapy, patients received efti (30 mg subcutaneously every 2 weeks for eight 3-week cycles and then every 3 weeks for up to 54 weeks) plus pembrolizumab (200 mg intravenously every 3 weeks for up to 105 weeks). The primary endpoint was the objective response rate by modified Response Evaluation Criteria in
