ATIM-16. PHASE 1 STUDY RESULTS OF M7824 (MSB0011359C), A BIFUNCTIONAL FUSION PROTEIN TARGETING TGF- AND PD-L1, AMONG PATIENTS WITH RECURRENT GLIOBLASTOMA (rGBM)

ABSTRACT: Abstract

BACKGROUND

TGF- signaling promotes tumor immunosuppression; TGF- inhibition in the tumor microenvironment may enhance the response to antiPD-L1 treatment. M7824 is an innovative, first-in-class, bifunctional fusion protein composed of a human antiPD-L1 IgG1 monoclonal antibody fused with two extracellular domains of TGF RII to function as a TGF- trap. We report safety and efficacy of M7824 in patients with rGBM.

METHODS

In this efficacy expansion cohort of the ongoing, phase 1 trial NCT02517398, patients with rGBM who progressed after chemoradiation received M7824 1200 mg q2w until disease progression, unacceptable toxicity, or trial withdrawal. The primary objective was disease control rate (DCR) per RANO; secondary objectives included safety/tolerability.
