Biocytogen/Eucure Biopharma's YH001 (Anti-CTLA-4 Monoclonal Antibody) Approved for Phase II Multi-Regional Clinical Trial by China National Medical Products Administration
2021.11.10


BEIJING, November 9, 2021 - Eucure Biopharma, a wholly owned subsidiary of Biocytogen dedicated to developing proprietary antibody drugs, announced that the China National Medical Products Administration (NMPA) has approved YH001 for phase II Multi-Regional Clinical Trials (MRCT) in China.


NMPA has approved Eucure Biopharma to conduct a phase II MRCT: a phase II, open-label, multi-center study (No. YH001004) will evaluate the safety and efficacy of YH001 in combination with Toripalimab (anti-PD-1 monoclonal antibody) for the treatment of patients with advanced non-small cell lung cancer (NSCLC) and hepatocellular carcinoma (HCC). The MRCT will be conducted in the United States, Australia and China. The trial has been previously approved by the US Food and Drug Administration (FDA) and Australia regulatory authorities.

Phase I dose-escalation study of YH001 in combination with Toripalimab in Australia (No. YH001002) evaluated the safety, tolerability, pharmacokinetics and preliminary efficacy of YH001 in patients with advanced solid tumors. 24 subjects with advanced solid tumors were enrolled and YH001 in combination with Toripalimab was well tolerated. Most of adverse events (AE) were grade 1 (22) and 2 (19), and Grade 3 or above AE were rare (2). No dose-limiting toxicity (DLT) event was observed. YH001 in combination with Toripalimab showed exciting antitumor activity in subjects with advanced solid tumors. There were 3 PR and 7 SD. YH001 in combination with Toripalimab showed a very benign safety profile and encouraging anti-tumor activity.

Dr. Yuelei Shen, Chairman and CEO of Biocytogen and Eucure Biopharma, said that the approval of the phase II MRCT of YH001 by China NMPA is a milestone for Biocytogen and Eucure Biopharma. Following the approval of the phase II MRCT of YH003 by the US FDA and China NMPA, YH001 is also approved for the phase II MRCT by the US FDA and China NMPA. This is an endorsement for YH001 and YH003 as well as Biocytogen’s antibody discovery platforms and Eucure Biopharma’s clinical development abilities. We will continue making rapid progress in the clinical development of YH001 in China and around the world and bring benefits to patients with new treatment options as soon as possible.

About YH001

YH001 is an anti-CTLA-4 monoclonal antibody which enhances our immune responses to tumor cells and the removal of regulatory T cells (Treg) from tumor microenviroment so as to treat multiple tumors. Blocking the inhibitory signals of anti-tumor responses to enhance the anti-tumor responses is considered to be the most promising tumor immunotherapy. CTLA-4 and PD-1 are considered as two important immune checkpoints. They control the activation of anti-tumor immune responses by regulating different types of T cells and they are considered to be the fundamental targets for tumor immunotherapy.
