The first half of 2025 promises to be pivotal for urological medicine, with four significant FDA decisions expected on treatments ranging from cancer therapeutics to novel antibiotics. These upcoming regulatory decisions could substantially impact the treatment landscape for various urological conditions.
Novel Prostate Cancer Imaging Agent Awaits March Decision
Telix Pharmaceuticals' TLX007-CDx, a cold kit for PSMA-PET imaging in prostate cancer, faces its FDA decision deadline on March 24, 2025. This innovative imaging agent utilizes gallium-68 from high-activity generators and cyclotrons, potentially offering enhanced distribution capabilities compared to existing PSMA-PET imaging agents.
Breakthrough UTI Treatment Under Priority Review
Following closely, the FDA will evaluate gepotidacin, a first-in-class triazaacenaphthylene antibiotic, by March 26, 2025. This novel treatment for uncomplicated urinary tract infections (uUTIs) has shown promising results in phase 3 trials. The EAGLE-2 trial demonstrated noninferiority to nitrofurantoin, with therapeutic success rates of 50.6% versus 47.0%. More impressively, the EAGLE-3 trial showed superiority, with success rates of 58.5% compared to 43.6% for nitrofurantoin.
Durvalumab's Potential Expansion into Bladder Cancer
In the second quarter of 2025, the FDA will decide on durvalumab (Imfinzi) for muscle-invasive bladder cancer (MIBC). The application, granted priority review, is supported by the phase 3 NIAGARA study's compelling results. The trial showed significant improvements in both event-free survival (67.8% vs 59.8% at 24 months) and overall survival (82.2% vs 75.2% at 24 months) when durvalumab was added to neoadjuvant chemotherapy.
Novel Treatment for Non-Muscle-Invasive Bladder Cancer
UGN-102's FDA decision is expected by June 13, 2025, for low-grade, intermediate-risk non-muscle-invasive bladder cancer. The phase 3 ENVISION trial demonstrated impressive efficacy, with a 79.6% complete response rate at three months. Notably, patients who achieved complete response showed an estimated 12-month duration of response of 82.3%, with sustained response rates of 80.9% at both 15 and 18 months.
These pending decisions represent potential significant advances in urological care, offering new options for both diagnosis and treatment across multiple conditions. The diversity of these applications - from imaging technologies to novel therapeutics - reflects the ongoing innovation in urological medicine and could significantly impact treatment protocols in the near future.
