> RMAT designation granted by FDA CBER for IMA203 cell therapy in multiple PRAME-expressing tumors including cutaneous and uveal melanoma, ovarian cancer and other cancer types

> Regulatory activities underway with an initial focus on a registration-directed trial in melanoma as step one to leverage the full breadth of PRAME


Immatics N.V. (NASDAQ: IMTX, “Immatics”), a clinical-stage biopharmaceutical company active in the discovery and development of T cell-redirecting cancer immunotherapies, today announced that its IMA203 TCR-T program has received Regenerative Medicine Advanced Therapy (RMAT) designation from the FDA Center for Biologics Evaluation and Research (CBER) in multiple relapsed and/or refractory HLA-A*02:01-positive and PRAME-expressing cancers, including cutaneous melanoma, uveal melanoma, endometrial carcinoma, synovial sarcoma, and ovarian cancer. IMA203 is a TCR-T cell therapy targeting PRAME, a protein frequently expressed in a large variety of solid tumors.

“The FDA RMAT designation for multiple indications underscores the broad potential of IMA203 and the benefits it may provide for advanced-stage solid tumor patients. This is an important regulatory milestone and a recognition of our clinical development progress for this program,” said Cedrik Britten, Chief Medical Officer of Immatics. “The close support from the FDA resulting from the RMAT status enhances our efforts to accelerate bringing IMA203 to cancer patients by enabling real-time discussions on patient populations, trial design and CMC.”

Established under the 21st Century Cures Act, RMAT designation is a dedicated program designed to expedite the development and review processes for promising pipeline products, including cell therapies, that includes all the benefits of Fast Track and Breakthrough designation programs. An investigational cell therapy is eligible for RMAT designation if it meets the definition of regenerative medicine therapy, it is intended to treat, modify, reverse, or cure a serious or life-threatening disease; and preliminary clinical evidence indicates that the therapy has the potential to address unmet medical needs for that disease. Advantages of the RMAT designation include early interactions with the FDA that may be used to discuss potential surrogate or intermediate endpoints for accelerated approval and potential ways to satisfy post-approval requirements, potential priority review of the biologics license application (BLA) and other opportunities to expedite development and review.

Based on publicly available information1, it is the Company’s understanding that this is the first time that FDA has granted a RMAT designation for an oncology drug candidate for more than two solid tumor indications. As of Sep 30, 2023, the U.S. FDA has received at least 238 requests for RMAT designations and granted 922.


About IMA203 and target PRAME

ACTengine® IMA203 T cells are directed against an HLA-A*02:01-presented peptide derived from preferentially expressed antigen in melanoma (PRAME), a protein frequently expressed in a large variety of solid cancers, thereby supporting the program’s potential to address a broad cancer patient population. Immatics’ PRAME peptide is present at a high copy number per tumor cell and is homogeneously and specifically expressed in tumor tissue. The peptide has been identified and characterized by Immatics’ proprietary mass spectrometry-based target discovery platform, XPRESIDENT®. Through its proprietary TCR discovery and engineering platform XCEPTOR®, Immatics has generated a highly specific T cell receptor (TCR) against this target for its TCR-based cell therapy approach, ACTengine® IMA203.

ACTengine® IMA203 TCR-T is currently being evaluated in three ongoing Phase 1b dose expansion cohorts in last-line patients: Cohort A IMA203 GEN1 monotherapy, Cohort B IMA203 in combination with an immune checkpoint inhibitor (deprioritized) and Cohort C IMA203CD8 GEN2 monotherapy, where IMA203 engineered T cells are co-transduced with a CD8aß co-receptor.


About ACTengine®

ACTengine® is a personalized cell therapy approach for patients with advanced solid tumors. The patient’s own T cells are genetically engineered to express a novel, proprietary TCR directed against a defined cancer target. The modified T cells are then reinfused into the patient to attack the tumor. The approach is also known as TCR-engineered cell therapy (TCR-T). All Immatics’ ACTengine® product candidates can be rapidly manufactured utilizing a proprietary manufacturing process designed to enhance T cell engraftment and persistence in vivo.

The ACTengine® T cell products are manufactured at the Evelyn H. Griffin Stem Cell Therapeutics Research Laboratory in collaboration with UTHealth.
