LVGN6051 is a humanized monoclonal antibody that specifically binds to CD137, and acts as an agonist against CD137.
This first in human study of LVGN6051 is designed to establish the maximum tolerated dose (MTD) and/or the recommended dose for expansion (RDE) as well as the recommended Phase 2 dose(s) (RP2D) of LVGN6051, both as a single agent (monotherapy) and in combination with a fixed dose of anti-PD-1 antibody (Pembrolizumab/MK-3475) in the treatment of advanced or metastatic malignancy.
