Xin Gao, MD, on Prostate Cancer: Early-Phase Results on Bavdegalutamide
2022 ASCO Genitourinary Cancers Symposium
Xin Gao, MD, of Massachusetts General Hospital, discusses phase I/II findings on bavdegalutamide, an androgen receptor protein degrader, which showed clinical activity in heavily pretreated patients with metastatic castration-resistant prostate cancer who received one to two prior novel hormonal agents.

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).

Axel S. Merseburger, MD, of the University Hospital Schleswig-Holstein, discusses results from a phase IIIb study of chemotherapy-naive patients with metastatic castration-resistant prostate cancer who have been treated with docetaxel plus prednisolone and experienced disease progression on enzalutamide. The data suggest that continued enzalutamide plus docetaxel improved progression-free survival compared with placebo plus docetaxel (Abstract 15).

Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses a 30-month follow-up of results from the KEYNOTE-564 trial, which further support the use of adjuvant pembrolizumab when treating patients with renal cell carcinoma at intermediate-high or high risk of recurrence, or with an M1 NED (no evidence of disease) status after nephrectomy. The data show a disease-free survival benefit vs placebo (Abstract 290).

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.

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).
