Prostate Cancer

On December 1, 2020, the FDA approved Gallium 68 PSMA-11 (Ga 68 PSMA-11; University of California), the first drug for positron emission tomography (PET) imaging of prostate-specific membrane antigen (PSMA)-positive lesions in men with prostate cancer. Ga 68 PSMA-11 is indicated for men with suspected metastatic prostate cancer that may be curable by surgery or by radiation, and for suspected recurrent prostate cancer based on elevated serum prostate-specific antigen (PSA) levels.

The combination of cabozantinib (Cabometyx), a kinase inhibitor, and atezolizumab (Tecentriq), a PD-L1 inhibitor, achieved clinically meaningful activity in patients with metastatic castration-resistant prostate cancer (CRPC), including those with high-risk clinical features, according to the results of the phase 1b COSMIC-021 trial presented at the ASCO 2020 virtual annual meeting.

Early results from the phase 2 TheraP clinical trial show that the targeted radiation therapy Lutetium-177 PSMA-617 (Lu-PSMA) significantly improved prostate-specific antigen (PSA) response compared with standard cabazitaxel in men with metastatic castration-resistant prostate cancer (CRPC) that progressed after docetaxel therapy.

No improvement in survival or in any key secondary end point was observed when the checkpoint inhibitor atezolizumab (Tecentriq) was added to enzalutamide (Xtandi) for the treatment of metastatic castration-resistant prostate cancer (CRPC) in the phase 3 IMbassador250 trial. The study results were presented at the 2020 American Association for Cancer Research virtual annual meeting.

On May 19, 2020, the FDA approved a new indication for olaparib (Lynparza; AstraZeneca), a PARP inhibitor, for the treatment of men with metastatic castration-resistant prostate cancer and deleterious or suspected deleterious germline or somatic HRR mutation, as determined by an FDA-approved test, whose disease progressed after enzalutamide (Xtandi) or abiraterone acetate (Zytiga) therapy. Olaparib is the first FDA-approved PARP inhibitor for prostate cancer.
