Investigators have developed α-therapeutic thorium-227-labeled DUNP19 ([227Th]Th-DUNP19), an antibody-conjugated radiopharmaceutical with high specificity and affinity to LRRC15.
A germline change in a single nucleotide increased the risk by up to 6-fold of developing an isocitrate dehydrogenase (IDH) mutant low-grade glioma. The rs55705857 genotype could serve as a biomarker before surgery to identify an early glioma.
Brain MRIs can reveal a great deal about brain tumors, but tracking response to treatment, clearly delineating edges and identifying other critical information remain problematic. Neosoma Inc.’s recently granted FDA 510(k) clearance may simplify treatment of the most challenging of these tumors, high-grade gliomas. The Neosoma High-Grade Glioma (HGG) neuro-oncology software device uses artificial intelligence to provide detailed measurements and 3D analysis that enable greater precision in procedures and better monitoring.
Merck KGaA has struck a collaboration and option-to-license deal with Nerviano Medical Sciences Srl centered around NMS-293, a next-generation PARP-1 inhibitor already in early clinical development for brain tumors. Merck is making a play for the poly (ADP-ribose) polymerase (PARP) inhibitor market, first opened up in December 2014 by Astrazeneca plc, when Lynparza (olaparib) was first approved in advanced ovarian cancer, going on to become a blockbuster through a partnership with Merck & Co Inc.
Epidermal growth factor receptor (EGFR) is a target in many cancers, but EGFR inhibitors have displayed little utility in treating glioblastoma (GBM) due to limited blood-brain barrier (BBB) penetration.
Sex differences at the cellular level could explain why men respond less well to glioblastoma (GBM) treatments, according to a study led by the Washington University School of Medicine in St. Louis (WUSTL). The researchers found that male and female GBM tumor cells had different metabolic needs. GBM cells from male surgical samples absorbed more glutamine and had different nutritional preferences for amino acids.
Tumor heterogeneity is recognized as an important way in which tumors are able to grow, invade surrounding tissue, metastasize and develop resistance to therapies. But linking specific states to the overall biology of tumors has been a challenge.
The U.S. FDA has granted Alpheus Medical Inc. orphan drug and fast track designations for a therapeutic platform that could improve outcomes for patients suffering from recurrent glioblastoma (GBM), the most common primary brain cancer and among the hardest to treat.
The U.S. FDA has given Sonalasense Inc. a green light to conduct two clinical trials in life-threatening brain tumors using sonodynamic therapy (SDT) and SONALA-001, an intravenous proprietary formulation of 5-aminolevulinic acid, or ALA. The studies – in diffuse intrinsic pontine glioma (DIPG) and recurrent glioblastoma (rGBM) – mark the first time SDT will have been used in clinical trials.
