Advances Cullinan's leadership in T cell engager (TCE) development for autoimmune diseases with both a CD19 TCE and BCMA TCE in its pipeline

Strengthens Cullinan portfolio of autoimmune programs with the opportunity to address a broader range of diseases while maintaining cash runway into 2028

Company to host conference call today at 4:30 pm ET

CAMBRIDGE, Mass., June 04, 2025 (GLOBE NEWSWIRE) -- Cullinan Therapeutics, Inc. (NASDAQ:CGEM, "Cullinan")), a biopharmaceutical company focused on developing modality-agnostic targeted therapies, today announced that it has entered into an agreement with Genrix Bio for a global (ex-Greater China), all indication, exclusive license to velinotamig, a BCMAxCD3 bispecific T cell engager. Velinotamig has demonstrated potential best-in-class efficacy at the Phase 2 target dose in nearly 50 patients with relapsed/refractory (r/r) multiple myeloma (MM). Cullinan will develop velinotamig in autoimmune diseases.

"We believe T cell engagers represent the next wave of innovation in autoimmune diseases, and we are excited to build upon our core T cell engager expertise and extensive KOL relationships to develop another potential best-in-class, clinical-stage program. Accumulated data supports BCMA as a promising target in autoimmune diseases, offering a precise and potentially disease-modifying approach by eliminating the entirety of the self-reactive plasma cells that result in certain autoimmune diseases, especially those diseases driven by long-lived plasma cells," said Nadim Ahmed, Chief Executive Officer of Cullinan Therapeutics. "Adding a BCMAxCD3 bispecific T cell engager to our pipeline complements our rapid global clinical development of CLN-978, enabling us to address the needs of more patients across a broader range of autoimmune diseases than with either molecule alone."

Genrix plans to initiate a Phase 1 study in China by the end of this year in patients with autoimmune diseases. Cullinan intends to use the data generated to accelerate global clinical development of the program. Following the completion of the Genrix Bio Phase 1 study, Cullinan will conduct all further development of velinotamig in autoimmune diseases.

"With our planned Phase 1 study of velinotamig in autoimmune diseases, we will be able to quickly leverage our experience in autoimmune diseases to complete the study in China expeditiously," said Dr. Liu Zhigang, Chairman, Chief Executive Officer, and Chief Science Officer of Genrix Biopharmaceutical "Cullinan is a proven leader in developing T cell engagers and we are confident in the company's ability to carry the program forward to address the needs of patients with autoimmune diseases."

Under the agreement, Cullinan will pay Genrix Bio an upfront license fee of $20 million for exclusive rights to develop and commercialize velinotamig in all disease areas globally outside of Greater China. In the future, Genrix will also be eligible to receive up to $292 million in development and regulatory milestones plus up to an additional $400M in sales-based milestones, as well as tiered royalties from mid-single digits up to the mid- teens on potential ex-Greater China net sales.

Importantly, with refinement of the clinical oncology pipeline, Cullinan reiterates its existing guidance to have cash resources into 2028 based on its current operating plan.

About Velinotamig

Velinotamig is a bispecific antibody that can simultaneously bind to the BCMA and CD3 antigens, redirecting cytotoxic T cells to target BCMA-expressing cells. Velinotamig has high affinity for BCMA and lower affinity for CD3. Affinity for BCMA is two orders of magnitude higher than for CD3, ensuring that the bispecific antibody recruits and activates T cells while minimizing non-specific T cell activation and reducing the toxicity mediated by the CD3 antibody.

Genrix Bio received approval from the National Medical Products Administration (NMPA) in January 2022 to conduct clinical trials for the indication of multiple myeloma. Velinotamig received Breakthrough Therapy Designation by the Center for Drug Evaluation (CDE) for the treatment of relapsed and refractory multiple myeloma.
