Gene clues reveal why some rare leukemia patients resist tagraxofusp therapy
medicalxpress - Researchers at The University of Texas MD Anderson Cancer Center have identified why some patients with a rare type of leukemia, called blastic plasmacytoid dendritic cell neoplasm (BPDCN), eventually develop resistance to tagraxofusp, the first Food and …
AI Summary: Researchers have identified decreased TXNRD1 and related molecular changes that appear linked to resistance against tagraxofusp in BPDCN patients. This insight exposes a plausible resistance mechanism and opens opportunities to test predictive biomarkers or combination strategies to overcome failure, which is welcome news for clinicians facing a stubborn, high‑risk disease.
First-in-human immunotherapy more than doubles progression-free survival in glioblastoma patients
medicalxpress - Glioblastoma, the most aggressive malignant brain tumor in adults, remains one of the most challenging cancers to treat because of limited treatment options and a poor prognosis. Patient outcomes have remained largely unchanged in the past two decades, un…
AI Summary: A first‑in‑human immunotherapy study in recurrent glioblastoma reported a more than twofold improvement in progression‑free survival, drawing attention to anti‑LAG‑3 strategies with or without anti‑PD‑1. While early and limited, the results provide a rare hint of efficacy in a notoriously treatment‑resistant cancer and warrant expedited follow‑up.
Meningococcal B vaccine ineffective in gonorrhea prevention for men who have sex with men
medicalxpress - The meningococcal B vaccine is ineffective in gonorrhea prevention among men who have sex with men (MSM) at high risk of infection, according to findings from the world's largest randomized controlled trial (RCT) into possible efficacy published in the Ne…
AI Summary: A major study found that the meningococcal B (MenB) vaccine does not provide protection against gonorrhea in men who have sex with men, contradicting earlier hopes that cross-protection might exist. Researchers emphasize the need for dedicated gonorrhea vaccines and continued public-health measures to control rising infection rates.
