Houston, Texas and Tuebingen, Germany, April 21, 2026 - Immatics N.V. (NASDAQ: IMTX, "Immatics" or the "Company"), the global leader in precision targeting of PRAME with multiple clinical-stage programs spanning cell therapies and bispecifics, today announced all submitted abstracts have been selected for oral presentations at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, to be held from May 29-June 2, 2026, in Chicago, Illinois, USA.
The four oral presentations will include:
- Phase 1b clinical data on anzu-cel, the Company's lead PRAME cell therapy, in advanced cutaneous and uvealmelanoma with a focus on characterizing response dynamics
- Updated Phase 1a dose-escalation and Phase 1b dose-expansion data for the second-generation (GEN2) PRAME cell therapy candidate, IMA203CD8, in gynecologic cancers at clinically relevant dose levels, which could support its development toward a tumor-agnostic approach
- Updated Phase 1 data on PRAME cell therapies in synovial sarcoma, further demonstrating the potential to address diverse tumor types beyond melanoma and gynecologic cancers
- Updated results for the MAGEA4/8 bispecific, IMA401, across multiple cancers, highlighting its potential as part of a combination approach with the Company's PRAME bispecific, IMA402, aimed at synergistic activity and expanded patient reach
Together, these data underscore the continued advancement of Immatics' PRAME franchise and its focus on developing novel immunotherapies for patients with solid tumors.
Full abstracts will be available on the ASCO website on May 21, 2026, at 5:00 pm ET.
