"The occurrence of immune-related adverse events is emerging as the Achilles’ heel of cancer immunotherapy," said Rachel W. Humphrey, M.D., chief medical officer of CytomX Therapeutics. "Our recently initiated Phase 1/2 clinical trial, part of our umbrella PROCLAIM program, is investigating the potential of our differentiated, anti-PD-L1 Probody therapeutic, CX-072, to reduce overactivation of the immune system outside of the tumor, while remaining active as a single-agent and in combination therapy. This poster presentation at ASCO (Free ASCO Whitepaper) will review the design and objectives of this ongoing study."

About the PROCLAIM-CX-072 Trial
PROCLAIM-CX-072 is the first clinical trial under the international umbrella program, PROCLAIM. The trial is an open-label, dose-finding Phase 1/2 study evaluating CX-072 as monotherapy and in combination with Yervoy (ipilimumab) or Zelboraf(vemurafenib). As part of the study, CytomX aims to achieve three goals as part of the PROCLAIM-072 clinical trial:

Tolerability: Demonstrate that CX-072 is well tolerated in patients and potentially improves safety, particularly in the combination setting.
Anti-cancer activity: Demonstrate initial evidence of CX-072’s anti-cancer activity as monotherapy and in combination.
Translational program and Probody platform proof-of-concept: Explore mechanistic aspects of Probody activity in patients as observed in preclinical studies.
