Also known as: Ewing sarcoma, Ewing Sarcoma
A first-in-human T-cell therapy showed lasting benefit in children with DIPG and relapsed CNS tumors, while a preclinical mRNA vaccine reduced neuroblastoma tumor size by 70%. Aneuploidy predicted response to olaparib plus irinotecan.
A major clinical trial found that Grail's Galleri blood test did not reduce late-stage cancer diagnoses, raising questions about multi-cancer early detection. Meanwhile, the FDA approved a second blood-based colorectal cancer screening test, and an AI-powered liquid biopsy showed promise for Ewing sarcoma.
A phase one trial of RSO-021 achieved disease control in 67% of relapsed mesothelioma patients. Other advances include daraxonrasib for NRAS-driven melanoma, an aneuploidy biomarker for PARP inhibitor response in childhood cancers, and new research into a cancer target and cholangiocarcinoma treatment.
A new antibody-drug conjugate targeting IL1RAP has shown potent preclinical activity against Ewing sarcoma and other fusion-driven cancers, with minimal off-target toxicity. Researchers at UBC report tumor eradication and reduced metastasis, with clinical trials being planned.
Soft tissue sarcoma pipeline activity includes 70+ companies and 75+ therapies. A phase II ADI-PEG 20 trial with gemcitabine and docetaxel was designed for sarcomas, while other 2026 studies span synovial sarcoma and unresectable advanced disease.
The largest CAR-T trial for pediatric solid tumors has opened in the US and UK, enrolling up to 60 young patients across four sites. The NexTGen study targets relapsed or refractory cancers and focuses first on safety and feasibility.
