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
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.
About YH003YH003 is a humanized IgG2 agonistic monoclonal antibody that targets CD40 signaling. Preclinical studies demonstrated that YH003 promotes antigen-presenting cell activation and infiltration of effector T cells into tumors. YH003 demonstrated potent anti-tumor effects in Biocytogen's humanized CD40 mice, both alone and in combination with anti-PD-1 monoclonal antibodies. YH003 has been approved to enter Phase II trials in Australia for pancreatic cancer and PD1-resistant melanoma.
About YH001YH001 is a humanized IgG1 monoclonal antibody that blocks the association of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) with CD80/CD86. YH001 can trigger antibody-dependent cell-mediated cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) to remove CTLA-4 expressing cells, especially regulatory T cells, to enhance T-cell-mediated antitumor immune responses. Preclinical data indicates that YH001 outperforms Ipilimumab (a currently approved CTLA-4 drug) in CTLA-4 binding affinity and inducing ADCC activity.
