Matthew R. Zibelman, MD, on Renal Cell Carcinoma: New Results on Combination of Nivolumab and Axitinib
2022 ASCO Genitourinary Cancers Symposium
Matthew R. Zibelman, MD, of Fox Chase Cancer Center, discusses phase I/II results from a study of treatment-naive patients with advanced renal cell carcinoma who received a combination of the immunotherapy (IO) nivolumab and the tyrosine kinase inhibitor (TKI) axitinib. The findings suggest that the efficacy of this regimen is comparable to that of currently available IO/TKI combinations for this population and has a similar safety profile (Abstract 291).

Fred Saad, MD, of the University of Montreal Health Centre, discusses phase III findings demonstrating for the first time the clinical benefits of olaparib plus abiraterone in patients with metastatic castration-resistant prostate cancer, irrespective of their homologous recombination repair mutation status. This regimen led to significantly longer radiographic progression-free survival than placebo plus abiraterone (Abstract 11).

Hielke-Martijn de Vries, MD, of the Netherlands Cancer Institute, discusses phase II findings on the use of atezolizumab with or without radiotherapy for patients with advanced squamous cell carcinoma of the penis. The study was designed to address the poor prognosis for this disease by exploring whether a protracted schedule of radiotherapy for locoregional disease, in combination with immunotherapy, could improve outcomes (Abstract 3).

Sumanta K. Pal, MD, of City of Hope National Medical Center, discusses some key research developments in kidney cancer, including data on nivolumab and ipilimumab with or without CBM588 in metastatic renal cell carcinoma; intestinal microbiome associated with the development of grade 3 or 4 adverse events in patients with metastatic disease who have been treated with nivolumab plus ipilimumab and probiotic support; the link between TERT promoter mutations and clinical outcome with immune checkpoint inhibitor therapy for advanced urothelial cancer; mutations in the androgen receptor gene in patients with prostate cancer receiving novel androgen deprivation treatments; and findings on waning antibody titers in patients who have received COVID-19 vaccinations (Roundup of Abstracts 371, 561, 374, Posters 38 and 48).

Alfredo Berruti, MD, of Italy’s University of Brescia, discusses the first study to give adjuvant mitotane to patients with adrenocortical carcinoma, a rare disease with a high risk of relapse after radical surgery. Although theoretically this treatment may be clinically worthwhile, the findings suggest that the need for adjuvant mitotane should always be discussed on a case-by-case basis by the multidisciplinary team, and more study is warranted (Abstract 1).

Karim Fizazi, PhD, MD, of Gustave Roussy and University of Paris-Saclay, discusses results from a first-in-human phase I/II trial, which showed that administering ODM-208—an oral, nonsteroidal inhibitor of the enzyme CYP11A1—to men with metastatic castration-resistant prostate cancer who were pretreated with abiraterone/enzalutamide and taxanes was effective in blocking the production of steroid hormones. It also showed antitumor activity, especially in men with AR mutation–positive cancers.
