A novel prostate-specific membrane antigen–targeted radiopharmaceutical for positron emission tomography known as 18F-DCFPyL, may help to identify occult prostate cancer and more accurately characterize disease burden, according to a subanalysis of the OSPREY trial presented during the 2021 Genitourinary Cancers Symposium.

In patients with nonmetastatic castration-resistant prostate cancer (nmCRPC), crossover from placebo to darolutamide (Nubeqa) appeared have minimal impact on the overall survival (OS) benefit observed with the androgen receptor inhibitor in the pivotal phase 3 ARAMIS trial.

The VEGF tyrosine kinase inhibitor tivozanib hydrochloride demonstrated a significantly increased quality-adjusted time without symptoms of disease and toxicity as third- or fourth-line therapy in patients with metastatic renal cell carcinoma compared with sorafenib in the phase 3 TIVO-3 trial.

Nivolumab plus cabozantinibreportedly improved health-related quality of life for patients with advanced renal cell carcinoma when compared to treatment with sunitinib.

A retrospective study has suggested that immunotherapy may have a great survival benefit in the frontline setting for patients with metastatic non–clear cell renal cell carcinoma (RCC) than select targeted therapies.

In the phase 3 ACIS study, the addition of apalutamide to abiraterone acetate lead to a reduction in the risk of radiographic progression or death by 30% in patients with chemotherapy-naïve metastatic castration-resistant prostate cancer receiving androgen deprivation therapy.

A subgroup analysis from the phase 3 JAVELIN Bladder 100 trial demonstrated that Japanese patients with advanced urothelial cancer whose disease did not progress on frontline chemotherapy benefited from the addition of avelumab to best supportive care in the first-line maintenance setting.

Response rates in patients with metastatic urothelial carcinoma were boosted when the novel PI3K-y inhibitor eganelisib was added to nivolumab, according to recent research presented during the American Society of Clinical Oncology 2021 Genitourinary Cancers Symposium.

In patients with clear cell renal cell carcinoma who had been treated with an immune checkpoint inhibitor in prior lines of therapy, lenvatinib in combination with everolimus was found to be safe and effective.

In an interview with Targeted Oncology, Martin T. King, MD, PhD,discusses INTREPId following his poster presentation of the trial design at the 2020 Genitourinary Cancer Symposium. He also discusses other another promising studies being presented at the conference.

Most patients with metastatic renal cell carcinoma whose disease progresses after immunotherapy given either alone or in combination with other agents receive subsequent treatment with VEGF tyrosine kinase inhibitors or mTOR inhibitors. When administered post-immunotherapy, cabozantinib is associated with superior median progression free survival, according to retrospective data from a real-world study of patients treated at 16 Italian referral centers.

Stereotactic body radiotherapy combined with nivolumab was associated with “high” disease control and overall survival rates in a phase II study of pretreated patients with metastatic renal cell carcinoma, according to lead investigator Cristina Masini, MD, who presented the data at the 2020 Genitourinary Cancers Symposium.

Combining a broad-spectrum tyrosine kinase inhibitor with an immune checkpoint inhibitor resulted in a high disease control rate in a preliminary dose-finding trial involving patients with advanced clear cell renal cell carcinoma.

A fourth of patients with advanced clear cell renal cell carcinoma responded to single-agent therapy with an oral hypoxia-inducible factor–2α inhibitor, which achieved a disease control rate of 80%, a preliminary clinical trial showed.

Nivolumab plus gemcitabine and cisplatin administered in the neoadjuvant setting to patients with muscle-invasive bladder cancer resulted in a pathologic nonmuscle-invasive rate of 66% and a pathologic complete response rate of 49%.

Bradley McGregor, MD, clinical director, Lank Center for Genitourinary Oncology, Dana-Farber Cancer Institute, senior physician, instructor in medicine, Harvard Medical School, discusses the goals of the phase III CheckMate-9ER trial, which is evaluating cabozantinib combined with nivolumab in previously untreated patients with advanced or metastatic renal cell carcinoma (RCC).

Apalutamide plus androgen deprivation therapy reduced the risk of second progression or death regardless of hormonal or taxane therapy as the first subsequent life-prolonging therapy in patients with metastatic castration-sensitive prostate cancer.

Men with metastatic castration-resistant prostate cancer had inferior immune responses with the combination of sipuleucel-T and radium-223 but improved clinical outcomes as compared with sipuleucel-T alone, a small randomized trial showed.
