About Givastomig

Givastomig (TJ033721 / ABL111) is a bispecific antibody targeting Claudin (CLDN) 18.2-positive tumor cells. It conditionally activates T cells through the 4-1BB pathway in the tumor microenvironment where CLDN18.2 is expressed. Givastomig appears to maintain strong tumor binding and anti-tumor activity, attributable to a synergistic effect of proximal interaction with CLDN18.2 and 4-1BB, while minimizing liver toxicity and systemic immunotoxicity commonly seen with other emerging 4-1BB-based product candidates. In March 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for givastomig for the treatment of gastric cancer, including cancer of the gastroesophageal junction. A Phase 1b study is ongoing evaluating givastomig, in combination with standard-of-care nivolumab plus chemotherapy, in treatment-naïve patients with gastric cancers, including gastroesophageal cancer (NCT04900818).

The program is being jointly developed through a global partnership with ABL Bio, in which I-Mab is the lead party and shares worldwide rights, excluding China and South Korea, equally with ABL Bio.
