Innovent Announces the First Patient Dosed in the Phase 1 Study of IBI321 (Anti-PD-1/TIGIT Bispecific Antibody) in Patients with Advanced Malignant Tumors
Innovent Biologics has begun dosing the first patient in its Phase 1 study of IBI321, an anti-PD-1/TIGIT bispecific antibody aimed at treating advanced malignant tumors. This open-label, multi-center trial focuses on evaluating the safety and preliminary efficacy of IBI321 in patients whose cancer has progressed despite standard therapies. With potential advantages over existing treatments, IBI321 targets both PD-1 and TIGIT pathways to enhance anti-cancer efficacy. The IND for IBI321 has been approved by the NMPA in China, and the trial is currently underway.
- First patient dosed in Phase 1 study of IBI321.
- IBI321 targets both PD-1 and TIGIT pathways, potentially improving treatment efficacy.
- IND approval from NMPA in China facilitates ongoing clinical trials.

SAN FRANCISCO and SUZHOU, China, July 25, 2021 /PRNewswire/ -- Innovent Biologics, Inc. (Innovent) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, today announced that the first patient has been dosed in a Phase 1 study of IBI321, an anti-PD-1/TIGIT bispecific antibody.
The objective of this open-label, multi-center Phase 1a dose escalation and expansion study is to evaluate the safety, tolerability, potential optimal dosage and preliminary efficacy of IBI321 in patients with advanced malignant tumors whose cancer progressed on standard-of-care treatment. The trial is being conducted in China.
As a bispecific antibody, IBI321 has the potential to enhance efficacy by synergistically targeting both PD-1 and TIGIT. Preclinical studies of IBI321 have shown that the molecule retained the activity of a PD-1 inhibitor and simultaneously suppressed TIGIT to enhance the anti-cancer efficacy.
Professor Baohui Han, Chief of Respiration Department and GCP center of Shanghai Chest Hospital, stated: "Although immune checkpoint inhibitors have shown great efficacy in a variety of tumor types, we still face challenges of primary and secondary drug resistance. Meanwhile, the efficacy of immune checkpoint inhibitors needs to be further improved. Therefore, the development of the next generation of bispecific antibodies has important clinical value. TIGIT is an important immune checkpoint receptor which plays an important role in tumor immune surveillance. We look forward to the clinical research results of IBI321."
Professor Xiangdong Cheng, secretary of party committee of Cancer Hospital of the University of Chinese Academy of Sciences (Zhejiang Cancer Hospital) and Chief of Zhejiang Province Upper Gastrointestinal Tumor Diagnosis and Treatment Technology Research Center, stated: "The progress of immunotherapy in certain types of colorectal cancer and gastric cancer has not been satisfactory compared with the progress of anti-PD-1 monoclonal antibodies in melanoma, lung cancer and esophageal cancer, and this needs further exploration. TIGIT is highly expressed in gastric cancer. And pre-clinical experiments have proved that synergistically targeting PD-1 and TIGIT could significantly repress gastric tumor growth. We look forward to the clinical results of IBI321, particularly in GI tumors."
Dr. Hui Zhou, Senior Vice President of Clinical Development of Innovent, stated: "By specifically targeting both PD-1 and TIGIT, this type of bispecific antibody is designed to provide synergistic effects by blocking both the PD-1/PD-L1 and TIGIT/CD155 pathways – with the goal of improving the anti-cancer efficacy. Currently, there is no bispecific antibody that has same target as IBI321 in clinical-stage development worldwide. Preclinical studies of IBI321 have demonstrated that the combination of these two monoclonal antibodies further enhanced the immune activation with improved convenience of administration. Therefore, the development of an anti-PD-1/TIGIT bispecific antibody has the potential to provide patients with more effective and convenient treatment. We look forward to hope that IBI321 will benefit more patients."
