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.
Wesley Yip, MD, of Memorial Sloan Kettering Cancer Center, discusses phase II results on neoadjuvant gemcitabine and cisplatin for high-grade upper tract urothelial carcinoma, which was well tolerated and demonstrated a favorable pathologic response rate. Dr. Yip notes that this treatment, given prior to nephroureterectomy, did not significantly delay surgery or increase perioperative complication rates.
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.
Massimo Di Maio, MD, of the University of Turin, discusses the Meet-URO12 study, which showed that maintenance niraparib plus best supportive care (BSC) did not prolong progression-free survival, compared with BSC alone, among patients with urothelial cancer that did not progress after first-line platinum-based chemotherapy.
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.
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).
