I-Mab , a U.S.-based, global biotech company, exclusively focused on the development and potential commercialization of highly differentiated immunotherapies for the treatment of cancer, today announced that it has entered into a clinical trial collaboration and supply agreement with Bristol Myers Squibb (NYSE: BMY). The collaboration will evaluate the combination of givastomig, an investigational Claudin 18.2 x 4-1BB bispecific antibody jointly developed by I-Mab and ABL Bio (KOSDAQ: 298380), with Bristol Myers Squibb's immune checkpoint inhibitor, nivolumab, and chemotherapy (FOLFOX or CAPOX), as a potential first-line treatment for patients with advanced Claudin 18.2-positive gastric and esophageal cancers.

Under the terms of the agreement, the study will be a multi-national Phase 1 study conducted by I-Mab. Bristol Myers Squibb will supply nivolumab. Nivolumab is an immune checkpoint inhibitor that is designed to block the PD-L1 protein on cancer cells from binding to PD-1, enhancing T-cell function and resulting in improved anti-tumor responses.

"We are pleased to enter into this clinical collaboration agreement with Bristol Myers Squibb as we embark on the next stage of givastomig's development to explore the significant promise of this bispecific antibody in a triple-therapy regimen," said Raj Kannan, CEO of I-Mab. "The study builds on the encouraging single-agent activity and safety we have observed with givastomig as presented at ESMO 2023. We remain optimistic that givastomig in combination with nivolumab and chemotherapy will drive potent anti-tumor activity in specific tumors, and we look forward to accelerating progress in the clinic."
