Eucure Biopharma to Present Findings From Anti-CD40 and Anti-CTLA-4 mAb Clinical Trials at the 2021 ASCO Meeting
BEIJING and BOSTON, June 1, 2021 /PRNewswire/ -- Eucure Biopharma will present findings from two Phase I clinical trials at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting, held from June 4th to 8th.
The first trial (poster #2580; NCT04481009) is designed to assess the safety, tolerability, pharmacokinetics and preliminary anti-tumor efficacy of YH003 (an anti-CD40 monoclonal antibody (mAb)) combined with Toripalimab (Tuoyi®; an anti-PD-1 mAb) in subjects with advanced solid tumors. As of December 31, 2020, there were no dose-limiting toxicity (DLT) events or severe adverse events (AE) observed in 9 subjects/3 dose levels (ranging from 0.03 to 0.3 mg/kg). Of the 5 subjects that completed at least one tumor assessment, one subject with ocular melanoma who failed prior Opdivo and Opdivo/Yervoy combination therapy achieved partial remission (PR), and two patients maintained stable disease (SD).
The second trial (poster #2577; NCT04357756) is a Phase I clinical study to evaluate the safety, tolerability, pharmacokinetics and preliminary anti-tumor efficacy of an anti-CTLA-4 antibody, YH001, combined with Toripalimab in subjects with advanced solid tumors. As of December 31, 2020, no DLT or severe AE were observed at 4 dose levels (ranging from 0.05 to 1 mg/kg). Seven of 10 subjects completed at least one tumor assessment, of which 4 subjects maintained SD. As of March 1, 2021, one subject with GEJ cancer that maintained SD in the first tumor assessment achieved PR in the second assessment, with a 60.9% reduction in the target lesion compared to baseline.
