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 metastatic gastric cancers, with additional potential in other solid tumors. In Phase 1 trials, givastomig was observed to maintain a strong tumor-binding property and anti-tumor activity, attributable to a potential synergistic effect of proximal interaction with CLDN18.2 and 4-1BB, while minimizing toxicities commonly seen with other 4-1BB agents.\n\nThe Company will focus its resources on advancing givastomig as its lead asset.\nTopline Phase 1 monotherapy dose escalation and dose expansion data presented at the annual meeting of the European Society for Medical Oncology (\"ESMO 2024\") showed:\n   \nAn overall response rate (\"ORR\") of 16.3% (7/43), including seven partial responses (\"PR\") at doses between 5 mg/kg and 18 mg/kg, with five of the seven responders (71%) having received prior checkpoint inhibitor (\"CPI\") therapy.\nA favorable safety profile, with mainly grade 1 or 2 treatment-related adverse events (\"TRAEs\"). No dose-limiting toxicities (\"DLTs\") were observed, and a maximum tolerated dose (\"MTD\") was not identified.\n\nA Phase 1b dose escalation study of givastomig in combination with nivolumab plus chemotherapy has been fully enrolled (n = 17) with no MTD reached and no DLTs to date; the Company expects to present these data in the early second half of 2025.\nBased on encouraging early data from the dose escalation study, the Company is expanding the previously planned dose expansion cohort (n = 6-8) to include two dose cohorts, each evaluating 20 patients, for a total of 40 patients.\n   \nPatients are being enrolled with tumors that express CLDN18.2 as low as 1+ intensity in ≥1% of cells, regardless of PD-L1 expression\nThe Company expects to share these data in early 2026.\n\nThis 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.\n\nAccording to Phillip Dennis, MD, PhD, CMO of I-Mab, \"Data arising from this study will not only help establish the breadth of patients who might respond to this novel regimen (such as those with low levels of CLDN18.2 expression that would not qualify for approved CLDN18.2 therapies), but also help establish the recommended dose of givastomig for subsequent studies.\"\nUliledlimab (TJ004309) is an antibody designed to target CD73, the rate-limiting enzyme critical for adenosine-driven immunosuppression in the tumor microenvironment. I-Mab owns worldwide rights to uliledlimab outside of Greater China.\n\nThe development of uliledlimab is being paused to allow the Company to focus resources toward advancing its lead clinical program, givastomig, and to allow data to mature from an ongoing China-only randomized study conducted by its partner TJ Biopharma evaluating uliledlimab in combination with a CPI (toripalimab) in CD73-high NSCLC patients.\nAs a result, further clinical investment in uliledlimab will be put on hold.\nThe Company will continue to monitor data as it becomes available.\nI-Mab is positioned to potentially resume clinical development, pending positive data.\n\nRagistomig (TJ-L14B / ABL503) is a bispecific, Fc-silent antibody designed to provide anti-PD-L1 activity and conditional 4-1BB-driven T-cell activation in one molecule. Ragistomig is being developed for solid tumors that are refractory or have relapsed after exposure to CPIs. The program is being jointly developed through a global partnership with ABL Bio, in which ABL Bio is the lead party and shares worldwide rights, excluding China and South Korea, equally with I-Mab.\n\nData reported by ABL Bio at the annual meeting of the American Society of Clinical Oncology (\"ASCO 2024\") showed promising objective responses in patients with various solid tumors whose tumors progressed or recurred after prior standard treatments, including patients with prior exposure to PD-(L)1 inhibitors.\nABL Bio is continuing the Phase 1b study to increase the therapeutic index by altering the dosing level and/or frequency, and to identify the appropriate tumor types for further development.\n\nFinancial Outlook\nThe Company's current cash position is expected to fund the givastomig Phase 1b study through dose expansion data readouts and further development initiatives into 2027.\nAbout I-Mab\nI-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.
