Key clinical point: The addition of bone resorption inhibitors (BRIs) to abiraterone acetate with prednisone prolongs overall survival (OS) in patients with metastatic castration-resistant prostate cancer (CRPC) and bone metastases. The OS was similar regardless of the BRI type used.

Major finding: The median follow-up was 23.5 months. Concomitant use of BRIs was reported in 29.0% of patients. BRI use was associated with OS improvement (31.8 months vs 23.0 months; hazard ratio [HR], 0.65; P less than .001) and shorter time to the first skeletal-related event (32.4 months vs 42.7 months; HR, 1.27; P = .04). Both denosumab and zoledronic acid were associated with similar OS (P = .79).

Study details: A retrospective study of 745 consecutive patients with metastatic CRPC and bone metastases who received abiraterone acetate plus prednisone between 2013 and 2016.

Disclosures: No funding source was reported. The authors received grants, personal fees, travel expenses, and research funding from and/or owned stocks in pharmaceutical companies outside the submitted work.

Key clinical point: Positive prostate-specific membrane antigen positron emission tomography (PSMA PET) findings prior to salvage radiotherapy (SRT) are associated with worse metastasis-free survival (MFS) in patients with recurrent prostate cancer.

Major finding: In 155 patients who underwent PSMA PET prior to SRT, 31.6% had positive PSMA PET. After propensity score matching, 5-year MFS was significantly lower in patients with “positive PSMA PET” vs those who did not undergo PSMA PET (48.5% vs 92.3%; P < .001). Positive PSMA PET imaging was associated with worse MFS compared with “no PSMA PET” (hazard ratio, 13.8; P < .001).

Key clinical point: A network meta-analysis suggests that relugolix, an oral gonadotropin-releasing hormone (GnRH) antagonist, had similar efficacy and safety to parenteral degarelix.

Major finding: Compared with GnRH agonists, there was no significant difference in castration rate at 12 months with relugolix (risk ratio [RR], 1.09; 95% credible interval [CrI], 0.95-1.23) and degarelix (RR, 0.98; 95% CrI, 0.91-1.06). Efficacy ranking analyses showed that relugolix was the most effective medical castration drug to induce sustained castration at 12 months. Compared with GnRH agonists, adverse events rates were similar with relugolix (RR, 0.99; 95% CrI, 0.6-1.6) and degarelix (RR, 1.1; 95% CrI, 0.75-1.35).

Key clinical point: In asymptomatic patients with nonmetastatic castration-resistant prostate cancer (CRPC), darolutamide vs placebo maintains health-related quality of life (QoL).

Major finding: Darolutamide vs placebo significantly delayed time to deterioration of Functional Assessment of Cancer Therapy-Prostate cancer subscale (hazard ratio [HR], 0.80; P = .0005), urinary symptoms (HR, 0.64; P < .0001), and bowel symptoms (HR, 0.78; P = .0027).

Study details: A study of patient-reported health-related QoL from randomized, double-blind, placebo-controlled, phase 3 ARAMIS trial, which evaluated 1,509 patients with nonmetastatic CRPC and prostate-specific antigen doubling time of 10 months or less who were randomly assigned 2:1 to receive darolutamide or placebo while continuing androgen deprivation therapy.

Disclosures: This study was funded by Bayer AG and Orion Pharma. The authors received grants, personal fees, and/or nonfinancial support from various sources. Some authors were employees of pharmaceutical companies.

Key clinical point: Cabazitaxel improves radiographic progression-free survival (rPFS) in older (age, 70 years and above) and younger (age, less than 70 years) patients with metastatic castration-resistant prostate cancer (CRPC) vs abiraterone or enzalutamide.

Major finding: The median rPFS significantly improved with cabazitaxel vs abiraterone/enzalutamide in older (hazard ratio [HR], 0.58; P = .012) and younger patients (HR, 0.47; P < .001). There was no significant improvement in overall survival with cabazitaxel in older (P = .084) and younger patients (P = .093).

Study details: An open-label, randomized CARD study of 255 patients with metastatic CRPC randomly assigned to either cabazitaxel plus prednisone and granulocyte colony-stimulating factor or enzalutamide/abiraterone+prednisone.

Disclosures: The study was funded by Sanofi. The authors reported grants or funding, honoraria, consulting/advisory fees, royalties, patents, employment/affiliation, and/or stock ownership/options.
