Immatics Showcases Key Advances in TCR-T Therapy Research

Immatics continues to establish itself as a leader in the cancer immunotherapy landscape with exciting advancements in TCR-T therapies directed against the PRAME antigen. Recently, the company announced plans to present multiple findings during the upcoming annual meeting of the Society for Immunotherapy of Cancer (SITC). These presentations highlight the progress that Immatics has made with its TCR-T candidates, emphasizing their potential to target solid cancers effectively.

TCR-T Therapy Developments

Immatics' ACTengine® IMA203 has showcased promising clinical data, reporting a clinical objective response rate (cORR) of 54% in heavily pretreated patients suffering from metastatic melanoma. Notable figures include a median duration of response (mDOR) of 12.1 months and a median progression-free survival (mPFS) of 6 months. What’s more, patients achieving deep responses have shown a remarkable mPFS exceeding a year. Plans are already underway for launching a randomized-controlled Phase 3 trial titled SUPRAME aimed at further validating IMA203 in the metastatic melanoma patient population.

Next-Generation Developments

The next-generation ACTengine® IMA203CD8 therapy is another exciting candidate in Immatics’ portfolio. It has been noted for its enhanced pharmacologic profile, demonstrating superior potency per cell, with the company reinitiating the Phase 1a dose escalation trial. Targeting PRAME, IMA203CD8 is being investigated for various solid tumors including ovarian and triple-negative breast cancers, which frequently express medium levels of PRAME.

Upcoming SITC Presentations

At the conference, Immatics will present both oral presentations and posters that reflect the latest updates on their clinical and preclinical candidates. Particularly, an update regarding IMA402, a Bispecific TCER candidate targeting PRAME, is highly anticipated. This report will provide critical insights from the ongoing Phase 1a dose escalation trial.

Continuous Innovation and Commitment

Immatics remains committed to advancing its pipeline, continually pushing the boundaries of TCR-T therapies. The company's strategy includes developing innovative preclinical models targeting both high and low PRAME-expressing tumors, utilizing technologies like membrane-bound IL-15 to enhance therapeutic efficacy.

Clinical Path Forward

In furthering its commitment to the clinical development of IMA203, Immatics anticipates the commencement of the SUPRAME trial targeting PRAME in December. This important Phase 3 trial will enroll approximately 360 patients who have previously undergone treatments with checkpoint inhibitors, setting the stage for a rigorous evaluation of IMA203 compared to existing therapies.

Immatics’ Vision and Mission

At the core of Immatics' philosophy is the belief in delivering breakthrough immunotherapies that provide patients with living therapies capable of targeting their tumors effectively. Furthermore, Immatics' proprietary technologies—XPRESIDENT® and XCEPTOR®—bolster their efforts in precisely identifying and engineering quality T cell receptors for better patient outcomes.
