The FDA has accepted the New Drug Application for giredestrant plus everolimus in ESR1-mutated, ER-positive, HER2-negative advanced breast cancer. The filing is based on Phase III evERA data showing reduced risk of disease progression or death versus standard-of-care endocrine therapy plus everolimus.
A JAMA Network Open study found high-dose vitamin D may reduce progression from prediabetes to type 2 diabetes in people with certain vitamin D receptor genotypes. In participants with ApaI CC or AC alleles, risk fell 19% versus placebo, while no reduction was seen in those with ApaI AA alleles.
Immunome submitted an NDA to the FDA for varegacestat in desmoid tumors after the Phase 3 RINGSIDE trial showed an 84% reduction in progression risk (HR=0.16) and a 56% objective response rate. The company plans to file in Q2 2026.
Phase III data showed dirozalkib improved progression-free survival and intracranial efficacy versus crizotinib in first-line ALK-positive advanced NSCLC. The drug received NMPA approval in August 2025.
The ASCENT-04 trial shows Trodelvy plus Keytruda extends progression-free survival by 3.4 months in PD-L1-positive metastatic triple-negative breast cancer. Meanwhile, the ToPCourT trial investigates trilaciclib combined with pembrolizumab and chemotherapy for advanced TNBC. These developments signal evolving treatment approaches for this aggressive breast cancer subtype.
The antibody-drug conjugate sacituzumab tirumotecan demonstrated significant survival benefits in pretreated EGFR-mutated NSCLC, with median overall survival of 20.0 months versus 13.5 months for docetaxel. The treatment also showed superior progression-free survival and objective response rates with a favorable safety profile compared to chemotherapy.
The SONIA trial found no overall survival benefit for first-line CDK4/6 inhibitors versus second-line use in advanced HR+/HER2- breast cancer. Median survival was 47.9 vs 48.1 months, though post hoc analysis suggested benefit in premenopausal patients. First-line treatment was associated with more severe adverse events.
A secondary analysis of the Southwest Oncology Group S1609 trial found that larger baseline tumor burden correlated with shorter overall survival but not progression-free survival in rare cancer patients treated with nivolumab plus ipilimumab. The study of 722 patients showed tumor burden was independently associated with survival outcomes but not predictive of tumor regression after dual immunotherapy.
The phase III TOP study shows osimertinib plus chemotherapy more than doubles progression-free survival to 34 months versus 15.6 months with osimertinib alone in EGFR/TP53 mutant NSCLC. The combination achieved an 82.9% response rate and represents a new strategy for this high-risk subgroup. Research continues into resistance mechanisms, including cancer-associated fibroblasts' role in promoting osimertinib resistance.
Sacituzumab tirumotecan demonstrated a median overall survival of 20.0 months versus 13.5 months with docetaxel in pretreated EGFR-mutated NSCLC patients. The phase 2 OptiTROP-Lung03 study showed a hazard ratio of 0.63 for overall survival benefit with the TROP2-directed antibody-drug conjugate.
