Key Genitourinary Cancers Clinical Trials to Watch

Key Genitourinary Cancers Abstracts | ASCO 2025

The 2025 ASCO Annual Meeting could reshape genitourinary (GU) Cancers (prostate, bladder, and kidney cancers). As new data emerges, a shift in clinical landscape is expected. The key abstracts within GU Cancers from DelveInsight listed below hold promise for significant advancements, aiming to positively impact the patient’s lives.

In clear cell renal cell carcinoma (ccRCC), two major abstracts are expected to be presented at ASCO 2025, i.e., Abstract 4515 (STELLAR-002 Study), and Abstract 4506 (ARC-20 Study). STELLAR-002 study explores triplet therapy as a potential breakthrough for metastatic ccRCC. COSMIC-313 study showed that cabozantinib in combination with OPDIVO and YERVOY improved progression-free survival (PFS) but had high rates of grade 3/4 treatment-related adverse events (AEs). The objective of STELLAR-002 study is to investigate whether zanzalintinib (a novel VEGF TKI with a shorter half-life) combined with OPDIVO and OPDUALAG could be a promising first-line triplet therapy for metastatic ccRCC.

Furthermore, ARC-20 Study examines the combination of casdatifan (a novel HIF-2⍺ inhibitor) with cabozantinib in previously treated metastatic ccRCC patients. Since new combinations are needed in RCC treatment, this regimen is advancing into a phase III trial. Preliminary data will be crucial as the study progresses, as this combination could potentially change clinical practice for patients with previously treated metastatic RCC.

In Prostate Cancer, PARP inhibitor data (Niraparib and abiraterone acetate plus prednisone) is set to be disclosed in patients with metastatic hormone-sensitive prostate cancer (mHSPC). Following multiple successful Phase III trials of PARP inhibitors combined with androgen receptor pathway inhibitors, assessing their effectiveness in earlier-stage disease of Prostate Cancer is important. The Phase III AMPLITUDE study (NCT04497844) could significantly influence mHSPC clinical practice, and the upcoming ASCO 2025 presentation could reveal whether it demonstrates an overall survival benefit. In addition to this, Candel Therapeutics is set to highlight positive Phase III results for CAN-2409 (ProstAtak) in newly diagnosed localized prostate cancer at ASCO 2025.
