The event will feature Samuel J. Klempner, MD (Associate Professor of Medicine at Massachusetts General Hospital), who will discuss new givastomig data in combination with immunochemotherapy. Givastomig, a potential best-in-class, Claudin 18.2 x 4-1BB bispecific antibody, is being evaluated in first line, Claudin 18.2-positive, metastatic gastric cancers. The data will be presented live at the European Society for Medical Oncology Gastrointestinal Cancers Congress (ESMO GI 2025) in a Mini Oral presentation on Wednesday, July 2, 2025, at 16:50 CEST (10:50am EDT).
This event will spotlight the first presentation of Phase 1b safety and efficacy results from the dose escalation study (n=17) evaluating givastomig in combination with nivolumab and chemotherapy for the first line treatment of Claudin 18.2-positive, metastatic gastric cancers.
A live question and answer session will follow the formal presentation. A replay of the webinar will be accessible on the News & Events page of the I-Mab website for 90 days.

About Givastomig
Givastomig (TJ033721 / ABL111) is a bispecific antibody targeting Claudin 18.2 (CLDN18.2)-positive tumor cells. It conditionally activates T cells through the 4-1BB signaling pathway in the tumor microenvironment where CLDN18.2 is expressed. Givastomig is being developed for first line (1L) metastatic gastric cancers, with further potential in other solid tumors. In Phase 1 trials, givastomig has shown promising anti-tumor activity attributable to a potential combined effect of proximal interaction between CLDN18.2 and 4-1BB, while minimizing toxicities commonly seen with other 4-1BB agents.
An ongoing Phase 1b study is evaluating givastomig for the treatment of gastric cancer in the 1L setting in combination with standard of care, nivolumab (an anti-PD-1 checkpoint inhibitor) plus chemotherapy, in dose escalation and dose expansion cohorts. Dose escalation is complete, and enrollment in the first dose expansion cohort (n=20) finished ahead of schedule. Enrollment continues to progress ahead of schedule in the second dose expansion cohort (n=20). The study builds on positive Phase 1 monotherapy data.
Givastomig is being jointly developed through a global partnership with ABL Bio, in which I-Mab is the lead party and shares worldwide rights, excluding Greater China and South Korea, equally with ABL Bio.
About I-Mab
I-Mab (NASDAQ: IMAB) is a U.S.-based, global biotech company, focused on the development of precision immuno-oncology agents for the treatment of cancer. The Company’s differentiated pipeline is led by givastomig, a potential best-in-class, bispecific antibody (Claudin 18.2 x 4-1BB) designed to treat Claudin 18.2-positive gastric cancers. Givastomig conditionally activates T cells via the 4-1BB signaling pathway in the tumor microenvironment where Claudin 18.2 is expressed. Givastomig is being developed for first-line metastatic gastric cancers, with additional potential in other solid tumors. In Phase 1 trials, givastomig was observed to maintain strong tumor-binding and anti-tumor activity, attributable to a potential synergistic effect of proximal interaction with Claudin 18.2 and 4-1BB, while minimizing toxicities commonly seen with other 4-1BB agents.
