SAN FRANCISCO and SUZHOU, China, June 3, 2024 /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, ophthalmology and other major diseases, announced that the clinical data of a randomized controlled Phase 1b study evaluating IBI310 (anti-CTLA-4 monoclonal antibody) in combination with sintilimab as neoadjuvant treatment of colon cancer was orally presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting (ClinicalTrials.gov, NCT05890742). The abstract was selected for ASCO Daily News coverage.
Based on the promising Phase 1b results, Innovent has opened the Phase 3 trial (Neoshot) evaluating IBI310 in combination with sintilimab as neoadjuvant treatment of colon cancer. The Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA) has also granted Breakthrough Therapy Designation (BTD) for IBI310.
Neoadjuvant treatment of IBI310 (anti-CTLA-4 antibody) plus sintilimab (anti-PD-1 antibody) in patients with microsatellite instability-high/mismatch repair-deficient colorectal cancer: results from a randomized, open-labeled, Phase 1b study
Abstract #: 3505
In this Phase 1b study, the efficacy and safety of IBI310 in combination with sintilimab versus sintilimab as neoadjuvant therapy for resectable stage IIB-III MSI-H/dMMR colon cancer was evaluated.
The Principal Investigator of the study, Prof. Ruihua Xu from Sun Yat-sen University Cancer Center, stated, “At present, complete (R0) resection for some stage IIB-III colon cancer patients remain a significant challenge, along with risks of extensive trauma and poor prognosis. In particular, neoadjuvant chemotherapy is not effective in MSI-H/dMMR colon cancer, and the pCR rate is only about 5%[1]. This Phase 1b study was the first randomized study to demonstrate the significant higher pCR rate of the dual immunotherapy in MSI-H/dMMR colon cancer. Neoadjuvant treatment of IBI310 in combination with sintilimab is potentially practice-changing that could reduce the preoperative staging, narrow the scope of radical resection, increase the complete resection rate, reduce the requirement of adjuvant chemotherapy and decrease the incidence of relapse, so as to improve the long-term prognosis and potentially cure the patients. The Phase 3 clinical study (Neoshot) is ongoing in China, and we look forward to positive results from this study to provide a more effective treatment option for patients with MSI-H/dMMR colon cancer.”
Dr. Hui Zhou, Senior Vice President of Innovent, stated, “There is a huge unmet clinical need for neoadjuvant therapy of resectable MSI-H/dMMR colon cancer in China. In this randomized, controlled Phase 1b study, IBI310 in combination with sintilimab significantly improved pCR rate than sintilimab alone in MSI-H/dMMR CRC with manageable safety profile. Based on the strong results of this study, we moved IBI310 in combination with sintilimab into Phase 3 trial (Neoshot) earlier this year, and we are looking forward to the positive results.”
About IBI310
IBI310 is a fully human monoclonal antibody injection independently developed by Innovent. IBI310 can specifically bind cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), thereby blocking CTLA-4 mediated T cell inhibition, promoting T cell activation and proliferation, improving tumor immune response, and achieving anti-tumor effects.
About Sintilimab
Sintilimab, marketed as TYVYT® (sintilimab injection) in China, is a PD-1 immunoglobulin G4 monoclonal antibody co-developed by Innovent and Eli Lilly and Company. Sintilimab is a type of immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells[2].
In China, sintilimab has been approved and included in the National Reimbursement Drug List (NRDL) for seven indications. The updated NRDL reimbursement scope for TYVYT® (sintilimab injection) includes:
Besides, the New Drug Application (“NDA”) for the combination of sintilimab and fruquintinib for the treatment of patients with advanced endometrial cancer with pMMR or non-MSI-H tumors that have failed prior systemic therapy but are not candidates for curative surgery or radiation has been accepted and granted priority review by the NMPA.
In addition, two clinical studies of sintilimab have met their primary endpoints:
