IBI-3003 / Innovent Biologics - LARVOL DELTA

Initial Results of the first-in-human Phase 1 study of IBI3003, a novel trispecific antibody targeting GPRC5D, BCMA and CD3, in patients with relapsed or refractory multiple myeloma (ASH 2025) - P1/2 | "The current follow-up period is relatively short, and the anti-tumor response is anticipated tobe more profound following continuous treatment. The dose escalation and expansion of IBI3003 isongoing in the phase 1 study."

ASH 2025 Oral Presentation: Innovent Biologics Announces Initial Results of the First-in-Human Phase 1 Study of Trispecific Antibody IBI3003 in Relapsed or Refractory Multiple Myeloma (PRNewswire) - "A total of 39 patients were enrolled in this phase in China and Australia, with a dose range of 0.1 μg/kg to 800 μg/kg....Encouraging efficacy was observed with a median follow-up of 3.25 months: Among patients treated with ≥120 μg/kg (n=24), the overall response rate (ORR) was 83.3%, including 4 cases of stringent complete response (sCR), 7 cases of very good partial response (VGPR), and 9 cases of partial response (PR). Among patients treated with ≥120 μg/kg, the ORR was 80% in 10 patients with EMD and 77.8% in 9 patients who had previously received anti-BCMA and/or anti-GPRC5D therapies."

VTS105: A novel and potent BCMA/GPRC5D/CD3 trispecific T cell engager (TCE) for the treatment of hematologic malignancies and autoimmune diseases (AACR 2025) - "Recently approved T cell engagers targeting BCMA (e.g., Teclistamab) and GPRC5D (e.g., Talquetamab) have demonstrated clinical responses; however, high relapse rates persist due to suboptimal complete response (CR) rates and minimal residual disease (MRD)...VTS105 exhibits potent human PBMC-mediated tumor cell killing across various heterogeneous MM cell lines, outperforming competitors such as JNJ-79635322, IBI3003, and SCR-8572...Evaluations in this indication are currently underway. Currently VTS105 is advancing into CMC and toxicology studies, with an Investigational New Drug (IND) filing planned for the second half of 2026."
