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.
Daniel P. Petrylak, MD, of Yale Cancer Center, discusses new data on the antitumor activity of neoadjuvant treatment with enfortumab vedotin-ejfv monotherapy in patients with muscle-invasive bladder cancer who are not eligible for cisplatin.
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.
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).
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).
Petros Grivas, MD, PhD, of the University of Washington and Fred Hutchinson Cancer Research Center, discusses results from Cohort 3 of the TROPHY-U-01 study, which assessed sacituzumab govitecan-hziy in combination with pembrolizumab in patients with metastatic urothelial cancer who experienced disease progression after platinum-based regimens (Abstract 434).
