PF-08046033 / Pfizer - LARVOL DELTA

PF-08046033 (GPS): A novel first in class auristatin S antibody-drug conjugate for treatment of GPNMB-expressing solid tumors (AACR 2026) - "A previous GPNMB-targeting ADC, Glembatumumab vedotin (GV), comprised of a monoclonal antibody (mAb) conjugated to the microtubule disrupting agent monomethyl auristatin E (MMAE), showed early signs of efficacy. Notably, in NHP toxicology studies, GPS was tolerated at 15 mg/kg, which is five-fold higher than GV. Altogether, these data support the evaluation of PF-08046033 (GPS) in a first-in-human phase 1 clinical trial for the treatment of multiple solid tumors."
