"We continue to advance our anti-CTLA-4 antibody trial, the antibody is well tolerated and shows early signs of efficacy, with a partial response observed in an individual patient," commented Jean-Marie Cuillerot, M.D., Chief Medical Officer. "A robust safety and tolerability profile and suggestion of clinical activity are consistent with our plans to combine this molecule with our anti-PD-1 antibody in the coming months."

Interim analysis of data collected as of May 16th, 2017 for 16 subjects, who have exhausted all standard of care options, demonstrated an acceptable safety and tolerability profile for AGEN1884 at the 0.1, 0.3, 1 and 3 mg/kg dose levels. A partial response was observed for a patient with angiosarcoma at week 33, with a 92% reduction in tumor volume upon treatment with 0.1 mg/kg of AGEN1884. While symptoms associated with immune-related adverse events were present, there were no dose-limiting toxicities reported to date.

AGEN1884 was developed under a Collaborative Research and Development Agreement between Ludwig Cancer Research, 4-Antibody AG and Recepta Biopharma S.A. AGEN1884 is partnered with Recepta Biopharma S.A. for certain South American rights.
