Jonathan E. Rosenberg, MD, on Urothelial Cancer: New Conclusions About Durvalumab Plus Olaparib
2022 ASCO Genitourinary Cancers Symposium
Jonathan E. Rosenberg, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II findings from the BAYOU trial, which studied durvalumab in combination with olaparib for first-line treatment of platinum-ineligible patients with unresectable, stage IV urothelial carcinoma. Because secondary analyses indicated a potential progression-free survival benefit with this combination, there may be a role for PARP inhibitors in the treatment of advanced disease with homologous recombination repair mutation (Abstract 437).

Tanya B. Dorff, MD, of City of Hope National Medical Center, discusses the first-in-human phase I findings showing that prostate stem cell antigen (PSCA) CAR T-cell therapy is feasible in patients with metastatic castration-resistant prostate cancer, with preliminary antitumor activity exhibited.

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.

Simon J. Crabb, PhD, MBBS, of the Southampton Experimental Cancer Medicine Centre, discusses data from the ATLANTIS trial, in which the authors hypothesized that switch maintenance therapy with the PARP inhibitor rucaparib, in patients who have derived clinical benefit from first-line chemotherapy, may improve outcomes for those with metastatic urothelial carcinoma that harbored a composite biomarker for DNA repair deficiency (Abstract 436).

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).

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).
