Immatics N.V. announced updated Phase 1 data for its IMA203CD8 PrameTCR T-cell therapy in gynecologic cancers and synovial sarcoma at the Annual Meeting of the American Society for Clinical Oncology, ASCO, in Chicago, IL, USA. One-time infusion of IMA203CD8 demonstrated meaningful clinical activity across different tumor types as well as manageable tolerability. The broad expression of PRAME in more than 50 cancers further supports the continued development of IMA203CD8 in multiple PRAME-positive solid tumors. IMA203CD8 demonstrated a manageable and consistent tolerability profile across patient populations. Clinical anti-tumor activity observed across tumor types with distinct biology and differing levels of PRAME expression, including lower PRAME levels in ovarian carcinoma. Clinical profile of IMA203CD8 supports continued development in gynecologic cancers and expansion into other PRAME-positive solid tumors. Determination of recommended phase 2 dose remains expected in 2026

Immatics Reports Promising IMA401 Clinical Data
- Significant Clinical Efficacy: IMA401 demonstrated a confirmed objective response rate (ORR) of 29% (4/14) and a disease control rate (DCR) of 64% (9/14) in head and neck cancer patients, with a median duration of response (mDOR) of 8.8 months, indicating its potential as a new treatment option for heavily pretreated patients.
- Good Tolerability: IMA401 showed favorable tolerability at the recommended Phase 2 dose (RP2D) with or without pembrolizumab, with the most common treatment-related adverse events being low-grade cytokine release syndrome (CRS) and lymphopenia, and no severe toxicities observed, supporting its broad combinability in treatment regimens.
- Combination Therapy Outlook: Immatics has initiated a clinical trial evaluating the combination of IMA401 and IMA402 in squamous cell non-small cell lung cancer (sqNSCLC), with initial data expected in 2027, as this dual-targeting strategy aims to cover over 90% of patients and enhance anti-tumor activity.
- Data Presentation Plans: Clinical data for IMA401 will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting on May 31, 2026, and published simultaneously in Nature Medicine, further enhancing the company's influence in the precision medicine field.

Immatics' PRAME T-Cell Therapy Shows Remarkable Efficacy
- Successful Case Treatment: At the Hopp Children's Cancer Center, a 17-year-old with nephroblastoma achieved significant tumor reduction and marked regression of liver, lung, and brain metastases after receiving Immatics' PRAME T-cell therapy, with ongoing remission at six months post-treatment, highlighting the therapy's potential in pediatric cancers.
- Clinical Data Presentation: The patient experienced a deep anti-tumor response three months post-treatment, with PET scans and MRIs showing significant regression across all lesions, and liquid biopsy monitoring indicated no tumor-derived DNA, confirming molecular remission and underscoring the efficacy of PRAME T-cell therapy.
