Glioblastomas (GBMs) are the most prevalent and highly lethal primary brain tumors and currently rely on limited treatment options. Chimeric antigen receptor (CAR) T cells targeting cell-surface antigens have shown promise in GBM patients, inducing transient tumor regression. However, the lack of known tumor-restricted antigens in GBM limits further improvement of their therapeutic efficacy.
Treatment in glioblastoma usually fails due to tumor heterogeneity and persistence of glioblastoma multiforme stem-like cells (GSCs) within the tumor margin. Researchers from Trogenix Ltd. engineered TGX-007, an AAV1-mediated therapeutic that delivers both cytotoxic and immunomodulatory genetic payloads to the tumor.
Researchers from Tango Therapeutics Inc. presented preclinical efficacy data on TNG-456, a selective MTA-cooperative PRMT5 inhibitor under development for the treatment of glioma and other tumors that frequently metastasize to the brain, such as non-small-cell lung cancer.
Vaxcellbio Co. Ltd. has signed a research agreement with the Korea Drug Development Fund (KDDF) to pursue the discovery of next-generation targeted anticancer lead compounds based on degradation of the molecular motor protein MYO1D (myosin 1D).
Researchers from Eilean Therapeutics LLC and collaborators presented the discovery and characterization of a new, selective CDK2 inhibitor showing potent in vitro and in vivo activity at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics.
In glioblastoma multiforme, MTAP loss leads to MTA accumulation, which partially inhibits PRMT5, making the cells reliant on residual PRMT5 activity for survival. Targeting this remaining PRMT5 with MTA-cooperative inhibitors induces synthetic lethality, representing a promising targeted approach for MTAP-deleted gliomas. Researchers from Ryvu Therapeutics SA reported the preclinical profile of RVU-305, a PRMT5 inhibitor, in MTAP-deleted cancer models.
Newco Trogenix Ltd. has emerged from incubation and raised £70 million (US$94.1 million) in a series A, as it prepares the ground for a U.S/U.K. clinical trial of a novel gene therapy construct in glioblastoma multiforme that is due to start at the beginning of 2026.
Glioblastoma multiforme (GBM) is the most common and aggressive malignant primary brain tumor in adults, marked by high treatment resistance and poor prognosis. OLIG2, a CNS-specific transcription factor essential for neural development, is highly expressed in GBM and contributes to tumor progression and therapy resistance, making it a promising target for novel therapeutic strategies.
