"Our focus in the first quarter of 2025 was led by the execution of our SUPRAME Phase 3 clinical trial in melanoma as well as our other clinical-stage PRAME product candidates," said Harpreet Singh, Ph.D., CEO and Co-Founder of Immatics. "At the upcoming ASCO (Free ASCO Whitepaper) Annual Meeting, we will present another Phase 1b clinical update on our PRAME cell therapy, IMA203, in melanoma with substantially longer follow-up. We also look forward to providing clinical trial updates for our cell therapy and bispecific programs later this year, highlighting the potential of our therapies in and beyond melanoma. We maintain a strong cash position, enabling us to rapidly advance the development of all our clinical programs, with a specific focus on progressing IMA203 toward commercialization and delivering this highly differentiated PRAME therapy to cutaneous and uveal melanoma patients with unmet medical needs as quickly as possible."

First Quarter 2025 and Subsequent Company Progress

PRAME Programs

IMA203 PRAME Cell Therapy
IMA203 is Immatics’ lead PRAME cell therapy, currently being evaluated in a Phase 3 trial (SUPRAME) in patients with previously treated advanced melanoma. IMA203 has the potential to become the first PRAME therapy to enter the market. In parallel, Immatics is preparing its in-house, state-of-the-art cell therapy manufacturing facility to serve its planned commercial supply. As part of maximizing the PRAME cell therapy opportunity, Immatics plans to expand IMA203 into uveal melanoma through the ongoing Phase 1b clinical trial. The current addressable patient population of PRAME/HLA-A*02:01-positive 2L unresectable or metastatic cutaneous melanoma in the US and EU52 is ~7,300 plus ~1,300 uveal melanoma patients in the US and EU5.

Phase 3 trial, SUPRAME, for IMA203 in previously treated, advanced cutaneous melanoma

Based on the positive Phase 1b clinical data, Immatics has advanced its PRAME cell therapy, IMA203, into a randomized-controlled Phase 3 clinical trial, SUPRAME, evaluating the efficacy, safety and tolerability of IMA203 TCR T-cell therapy vs. investigator’s choice of treatment in patients with unresectable or metastatic cutaneous melanoma who have received prior treatment with a checkpoint inhibitor.
Primary endpoint for seeking full approval will be blinded independent central review ("BICR")-assessed (RECIST v1.1) progression-free survival (PFS). Secondary endpoints for the trial include objective response rate (ORR), safety, duration of response (DOR), overall survival (OS) and patient-reported outcomes.
The trial will be conducted internationally with approximately 50 sites in the US and Europe.
Patient enrollment and randomization for the trial was initiated in early 2025 and is expected to be completed in 2026. In April 2025, Immatics received regulatory approval from the German regulatory authority, Paul-Ehrlich-Institute (PEI), to commence the IMA203 SUPRAME Phase 3 trial in Germany.
A pre-specified interim data analysis will be triggered upon the occurrence of a defined number of events for PFS (progressive disease or death)3, anticipated to occur after approximately 200 patients. Immatics aims to submit a Biologics License Application (BLA) in 1Q 2027 for full approval.
IMA203 PRAME cell therapy development is supported by the FDA RMAT designation. Advantages of the RMAT designation (which includes all benefits of Breakthrough Therapy designation) include potential priority review of the BLA and frequent interactions with the US FDA as an opportunity to expedite development and review.
A trial-in-progress poster on SUPRAME will be presented in a poster presentation by the SUPRAME lead principal investigator, Jason Luke, MD, FACP, FASCO, at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting on June 2, 2025.

Phase 1b trial for IMA203 PRAME cell therapy in solid tumors with a focus on uveal melanoma

In addition to cutaneous melanoma, Immatics intends to expand the IMA203 opportunity to treat uveal melanoma patients and will continue to evaluate IMA203 in this patient population through the ongoing trial.
Updated data from the Phase 1b trial of IMA203 in metastatic melanoma with substantially longer follow-up compared to the last presentation in October 2024, and including data from additional uveal melanoma patients enrolled since then, will be highlighted by Martin Wermke, MD, in an oral presentation at the 2025 ASCO (Free ASCO Whitepaper) Annual Meeting on May 31, 2025.
In April 2025, Nature Medicine published a manuscript covering prior clinical results on IMA203. The publication includes data from 40 heavily pretreated patients with PRAME cancers, mostly treated during the Phase 1a dose escalation part of the trial.

Cell therapy manufacturing capabilities

The IMA203 PRAME cell therapy products are manufactured from a patient’s leukapheresis (with no surgery required) within 7-8 days, followed by 7-day QC release testing at >95% success rate4 to achieve the target dose (1-10×109 TCR T cells).
Immatics’ proprietary manufacturing process, timeline, capabilities and facility support late-stage clinical development and commercial cell therapy supply.
IMA203CD8 PRAME Cell Therapy (GEN2)
IMA203CD8 is the Company’s second-generation cell therapy product candidate targeting PRAME. Given its pharmacology profile, once the target dose is reached, the Company intends to pursue the clinical development of this product in multiple PRAME cancers, starting with gynecologic cancers.

Clinical data demonstrated enhanced pharmacology of IMA203CD8, which opens the possibility of addressing hard-to-treat solid tumor indications with both high- and medium-level PRAME copy numbers, such as ovarian cancer, uterine cancer, squamous non-small cell lung carcinoma, triple negative breast cancer and others.
Phase 1a dose escalation in solid tumors is ongoing to evaluate higher doses of IMA203CD8 with and without IL-2. As of today, patients are being treated with up to ~8 billion total GEN2 TCR T cells.
The next clinical trial update, which will report on the continued dose escalation in multiple PRAME cancers, including ovarian cancer patients treated at relevant doses, is planned in 2025.

IMA402 PRAME Bispecific

To expand the PRAME opportunity to additional solid cancer types and earlier lines of treatment, the Company is developing its half-life extended TCR Bispecific, IMA402. Upon delivering clinical proof-of-concept ("PoC") in last-line melanoma, Immatics plans to explore its potential in gynecologic cancers, NSCLC, breast cancer, and other solid tumor indications as well as earlier treatment lines of solid cancers, such as first-line (1L) cutaneous melanoma.

First clinical data from the early Phase 1a dose escalation trial demonstrated initial signs of dose-dependent and PRAME target expression-dependent clinical activity.
Phase 1a dose escalation at higher dose levels to determine the optimal therapeutic dose is advancing and currently ongoing at dose level 11 (12 mg).
The next Phase 1a clinical trial update with clinical data at relevant dose levels in second-line or later (2L) melanoma is planned in 2025.

Combination of IMA203 PRAME Cell Therapy and PRAME Adaptive Immune Modulating Therapy

In February 2025, the FDA granted IND clearance for a Phase 1 trial evaluating Immatics’ IMA203 PRAME cell therapy in combination with Moderna’s PRAME adaptive immune modulating therapy. The first-in-human, Phase 1a/1b trial is a multicenter, open-label, dose escalation/de-escalation (adaptive design) trial evaluating the safety, tolerability and efficacy of the combination therapy in an estimated 15 patients with advanced or recurrent cutaneous melanoma and synovial sarcoma. Immatics is responsible for conducting the Phase 1 trial. Each party retains full ownership of its investigational PRAME compound, and the parties will fund the clinical study on a cost sharing basis. In November 2024, Immatics presented preclinical proof-of-concept data at SITC (Free SITC Whitepaper) supporting this combination.

Other Programs

IMA401 MAGEA4/8 Bispecific
Immatics is further harnessing the potential of its proprietary bispecific platform to develop innovative therapeutics and unlock more cancer types. The Company’s half-life extended TCR Bispecific, IMA401 targeting MAGEA4/8, is progressing through a Phase 1 trial in patients with late-stage NSCLC, head & neck cancer, bladder cancer and other solid tumor indications, with the primary goal of developing this product candidate in earlier treatment lines.

Clinical proof-of-concept data from the Phase 1a dose escalation trial showed initial anti-tumor activity in multiple tumor types, including durable confirmed objective responses, a manageable tolerability profile and a half-life of 14+ days, which supported the switch to q2w dosing (once every two weeks).
The Phase 1a trial is ongoing and the Company continues to focus enrollment on indications with high MAGEA4/8 target expression, such as lung and head and neck cancer.
Dose refinement for IMA401 as monotherapy and in combination with a checkpoint inhibitor is ongoing. Through the combination, Immatics aims to generate relevant clinical data to position IMA401 as a combination therapy in earlier treatment lines.
The next update on IMA401 Phase 1a data, with a focus on head and neck cancer, is expected in 2025, and the Company plans to share data with a focus on non-small cell lung carcinoma in 2026.
Moderna Collaboration
Immatics generated regulatory support data for one of Moderna’s mRNA product candidates that leveraged Immatics’ XPRESIDENT and its bioinformatics and AI platform XCUBE. Pursuant to the Collaboration Agreement under the Database/Vaccine Program, Immatics received a milestone payment triggered by the initiation of the first Phase 1 clinical trial for the Moderna product candidate.
