IBI3003 was discovered and developed using Innovent’s proprietary Sanbody platform and its development is being advanced globally. IBI3003 is currently undergoing a Phase 1/2 clinical trial in patients with relapsed or refractory multiple myeloma in China and Australia, and there are plans to initiate a Phase 1/2 clinical trial in the United States imminently.

Clinical data presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting on December 7, 2025[Link], demonstrated a tolerable safety profile and promising efficacy signals for IBI3003 in patients who had failed ≥2 prior lines of myeloma therapy:

Thirty-nine patients with R/R MM who had previously received at least a PI, an IMiD, and an anti-CD38 monoclonal antibody were treated with IBI3003 at dose levels ranging from 0.1 μg/kg to 800 μg/kg and underwent at least one tumor assessment after baseline. As of the data cutoff date of November 7, 2025, the median follow-up duration was 3.25 months (range: 0.4–7.4), and the median treatment duration was 12.14 weeks (range: 1.0–33.0).
Among patients treated at doses ≥120 μg/kg (n=24), the overall response rate (ORR) was 83.3%, including 4 stringent complete responses (sCR), 7 very good partial responses (VGPR), and 9 partial responses (PR). In this cohort, the ORR was 80% among 10 patients with extramedullary disease (EMD) and 77.8% among 9 patients previously treated with BCMA- and/or GPRC5D-directed therapies. Among patients who achieved complete response or better, the minimal residual disease (MRD) negativity rate was 100% (n=4), as assessed by validated next generation sequencing, with a threshold of 10-5, performed at a central laboratory.
All cases of cytokine release syndrome (CRS) were Grade 1-2, with only 2 cases of Grade 1-2 immune effector cell-associated neurotoxicity syndrome (ICANS) reported. Most treatment-emergent adverse events (TEAEs) related to GPRC5D targeting, including those affecting the oral cavity, skin, and nails, were Grade 1–2, with two patients experiencing Grade 3 rash.
Dr. Hui Zhou, Chief R&D Officer of Oncology in Innovent, stated, "IBI3003 monotherapy has demonstrated encouraging efficacy and a favorable safety profile in R/R MM patients who had received three or more prior lines of therapy. Notably, meaningful clinical activity was observed even in high-risk patients with EMD or those previously treated with anti-BCMA and/or GPRC5D-targeted therapies, highlighting IBI3003’s potential to address key unmet needs. Its overall manageable safety profile further supports continued investigation and the potential for durable survival benefit. The Fast Track Designation granted by the U.S. FDA represents an important milestone in the global development of IBI3003, and we look forward to further evaluating its potential to benefit patients worldwide."

Fast Track Designation is intended to facilitate the development and expedite the review of drugs that treat serious conditions and address unmet medical needs. Programs granted FTD benefit from more frequent interactions with the FDA, which may accelerate clinical development and regulatory review.

About IBI3003 (Anti-GPRC5D/BCMA/CD3 Trispecific Antibody)

IBI3003 is a tri-specific TCE developed using Innovent’s proprietary Sanbody platform to target both GPRC5D and BCMA. The molecule is designed to mitigate tumor escape associated with single-antigen targeting. In preclinical studies, IBI3003 demonstrated superior in vitro and in vivo antitumor activity compared with marketed benchmark T-cell engagers, including in cell lines and xenograft models with low BCMA and GPRC5D expression. A Phase 1/2 clinical trial (NCT06083207) is ongoing in China and Australia. In December 2025, IBI3003 received IND approval from the U.S. FDA, enabling initiation of a Phase 1/2 clinical trial in the United States.

About Multiple Myeloma

Multiple myeloma (MM) is a malignant hematologic disease characterized by the clonal proliferation of plasma cells and is the second most common hematologic malignancy [1]. MM remains incurable, and factors such as inadequate depth of response, extramedullary involvement, and short remission duration are associated with poor prognoses [2]. For patients with R/R MM who have received four or more prior lines of therapy, including exposure to PIs, IMiDs, and anti-CD38 antibodies, treatment options include, but are not limited to, BCMA-targeted CAR-T therapies and bispecific antibodies targeting CD3×BCMA or CD3×GPRC5D. However, the benefits of these approaches may be limited by antigen loss and treatment resistance.
