Core Insights - Celcuity Inc. announced significant efficacy and safety results from the Phase 3 VIKTORIA-1 clinical trial of gedatolisib for advanced breast cancer, showing a 76% reduction in disease progression risk with the triplet therapy compared to fulvestrant [1][3][6] Efficacy Results - The gedatolisib triplet therapy achieved a median progression-free survival (PFS) of 9.3 months, an improvement of 7.3 months over fulvestrant, with a hazard ratio (HR) of 0.24 [3][6] - The objective response rate (ORR) for the triplet was 31.5%, while the doublet showed an ORR of 28.3% [3][6] - For the gedatolisib doublet, the median PFS was 7.4 months, an improvement of 5.4 months over fulvestrant, with a HR of 0.33 [3][6] Safety Profile - Hyperglycemia occurred in 9.2% of patients on the triplet and 11.5% on the doublet, with treatment discontinuation due to adverse events at 2.3% and 3.1%, respectively [5][7] - The most common grade 3 treatment-related adverse events included neutropenia (52.3% for triplet), stomatitis (19.2% for triplet), and hyperglycemia (2.3% for triplet) [7] Clinical Significance - The results from the VIKTORIA-1 trial represent a potential new standard of care for patients with HR+/HER2- advanced breast cancer who have progressed after CDK4/6 inhibitor treatment [7][9] - Gedatolisib is the first inhibitor targeting the PI3K/AKT/mTOR pathway to show positive Phase 3 results in this patient population [6][9] Future Developments - Celcuity has initiated a rolling New Drug Application (NDA) submission to the FDA, targeting completion in Q4 2025 [9] - The PIK3CA mutant cohort of the VIKTORIA-1 trial is fully enrolled, with topline data expected in late Q1 or Q2 2026 [9]

Core Insights - Recent advances in understanding the pathogenesis of venous malformations (VMs) highlight the PI3K/AKT/mTOR pathway as a key driver of disease proliferation, leading to increased off-label use of systemic rapamycin (sirolimus) for treatment [1][4] - A systematic review of 26 studies involving 98 patients treated with rapamycin for VMs supports the clinical potential of Palvella's QTORIN™ 3.9% rapamycin anhydrous gel, which is currently under evaluation in the Phase 2 TOIVA trial [2][3] Company Overview - Palvella Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on developing therapies for serious, rare genetic skin diseases without FDA-approved treatments [7] - The company is developing a pipeline based on its patented QTORIN™ platform, with QTORIN™ rapamycin being its lead product candidate [7] Industry Context - There is a significant unmet clinical need for effective treatments for cutaneous VMs, with no FDA-approved pharmacologic options currently available [2][6] - The estimated number of diagnosed patients with cutaneous VMs in the U.S. exceeds 75,000, highlighting the urgency for targeted therapies [5][6] Clinical Findings - The systematic review indicates that off-label use of rapamycin has shown efficacy in improving various clinical signs, including bleeding and quality of life, despite inadequate responses to standard treatments [4] - A targeted, topical formulation of rapamycin could provide clinical benefits by achieving therapeutic levels in the dermis while minimizing off-target effects associated with oral rapamycin [4] Regulatory Status - In April 2024, the FDA granted Fast Track Designation to QTORIN™ rapamycin for the treatment of VMs, indicating the potential for expedited development and review [5]

Core Insights - Celcuity Inc. announced positive topline results from the Phase 3 VIKTORIA-1 clinical trial for gedatolisib in combination with fulvestrant, showing significant improvements in progression-free survival (PFS) for patients with HR+/HER2- advanced breast cancer [2][5][9] Efficacy Results - The gedatolisib triplet (gedatolisib + palbociclib + fulvestrant) reduced the risk of disease progression or death by 76% compared to fulvestrant, with a median PFS of 9.3 months versus 2.0 months, representing an incremental improvement of 7.3 months [3][6][7] - The gedatolisib doublet (gedatolisib + fulvestrant) reduced the risk of disease progression or death by 67%, with a median PFS of 7.4 months compared to 2.0 months for fulvestrant, an incremental improvement of 5.4 months [4][6][7] Historical Significance - The hazard ratios for both the gedatolisib triplet and doublet are the most favorable reported in any Phase 3 trial for HR+/HER2- advanced breast cancer [7] - The incremental improvements in median PFS for both regimens are unprecedented for patients receiving at least their second line of therapy in this category [7][8] Safety Profile - Treatment discontinuation due to treatment-related adverse events for both the gedatolisib triplet and doublet was lower than observed in previous trials, indicating a favorable safety profile [6][8] - Lower rates of hyperglycemia and stomatitis were reported compared to earlier studies, suggesting better tolerability of the gedatolisib regimens [6][8] Future Developments - Full data from the VIKTORIA-1 trial will be presented at an upcoming medical conference, and Celcuity plans to submit a New Drug Application for gedatolisib to the FDA in Q4 2025 [5][9]
