Clinical benefit of the gedatolisib regimens was consistent across patient subgroups Hyperglycemia was reported in only 9.2% of patients treated with gedatolisib + palbociclib + fulvestrant (“gedatolisib triplet”) and in 11.5% of patients treated with gedatolisib + fulvestrant (“gedatolisib doublet”) Study treatment discontinuation due to treatment related adverse events was reported in 2.3% of patients treated with the gedatolisib triplet and 3.1% of patients with the gedatolisib doublet Management to host webcast and conference call October 20, 2025 , at 8:00 a.m. ET MINNEAPOLIS , Oct. 18, 2025 (GLOBE NEWSWIRE) -- Celcuity Inc. (Nasdaq: CELC), a clinical-stage biotechnology company pursuing development of targeted therapies for oncology, today announced detailed efficacy and safety results from the PIK3CA wild-type (“WT”) cohort of the Phase 3 VIKTORIA-1 clinical trial of gedatolisib, an investigational pan-PI3K/mTORC1/2 inhibitor, in adults with hormone receptor positive (“HR+”), human epidermal growth factor receptor 2 negative (“HER2-“), PIK3CA WT, advanced breast cancer (“ABC”), following progression on, or after, treatment with a CDK4/6 inhibitor and an aromatase inhibitor. As previously announced, the gedatolisib triplet demonstrated a statistically significant and clinically meaningful improvement in median progression-free survival (“PFS”) versus fulvestrant, reducing the risk of disease progression or death by 76%. The gedatolisib doublet reduced the risk of progression or death by 67% versus fulvestrant. The detailed study results were presented at a late breaking oral presentation at the European Society for Medical Oncology (ESMO) Congress today, Saturday, October 18 at 4:25 a.m. ET / 10:25 a.m. CEST . In the trial, median PFS with the gedatolisib triplet was 9.3 months versus 2.0 months with fulvestrant, an incremental improvement of 7.3 months (HR=0.24; 95% CI: 0.17-0.35; p
