BACKGROUND: Despite standard-of-care androgen-deprivation therapy and an increasing number of treatment options, the mortality rate for prostate cancer remains high. Progress to metastatic castration-resistant prostate cancer (mCRPC) necessitates additional treatments. Abiraterone acetate plus prednisone or prednisolone (AAP) prolongs survival in chemotherapy-naive and docetaxel-experienced patients. OBJECTIVE: To evaluate the real-world safety and efficacy of AAP as first-line and second-line [post-docetaxel only (AAP-PD)] treatment in patients with mCRPC. PATIENTS AND METHODS: The Prostate Cancer Registry (PCR) was a prospective, international, observational study of patients with mCRPC in routine clinical practice. Men aged ≥ 18 years with confirmed mCRPC were included. Baseline characteristics, safety (treatment-emergent adverse events, treatment-emergent severe adverse events), and efficacy [progression-free survival (PFS) and overall survival (OS)] were analyzed. RESULTS: At baseline, patients who received first-line AAP (n = 754) were generally older than patients who received AAP-PD (n = 354); median age was 76 years and 70 years, respectively. However, the rate of visceral metastasis was higher in the AAP-PD cohort than in the AAP cohort (17.7% vs. 9.6%, respectively). Demographics and disease characteristics of patients with baseline cardiovascular disease were similar to those of the overall registry population. Efficacy outcomes were similar for all patients, regardless of the line of AAP therapy. For first-line AAP and AAP-PD, respectively, the median PFS was 8.9 and 5.8 months for all patients and 9.1 and 6.0 months for patients with cardiovascular comorbidities; median OS was 27.1 and 23.4 months for all patients, and 27.4 and 23.1 months for patients with cardiovascular comorbidities. There were no unexpected adverse events in any patient subgroup. CONCLUSIONS: These real-world data complement the findings from randomized controlled trials, indicating that first- and second-line AAP is well tolerated and effective in patients with mCRPC, including those with underlying CV comorbidities.

BACKGROUND: Metastatic prostate cancer has a 30% 5-year survival rate despite recent therapeutic advances. There is a need to improve the clinical understanding and treatment of this disease, particularly in the real-world setting and among patients who are under-represented in clinical trials. OBJECTIVE: We aimed to evaluate the characteristics and clinical outcomes of patients who received their first treatment for metastatic castration-resistant prostate cancer (mCRPC) in routine clinical practice, independent of treatment used, including subgroups with baseline cardiac disease, diabetes mellitus, or visceral metastases. PATIENTS AND METHODS: Prospective, noninterventional analysis of patient record data in the multicenter Prostate Cancer Registry (PCR) of men with mCRPC. The data were collected in 16 countries with the aim of recruiting more than 3000 patients between 2013 and 2016. The study end date was 9 July 2018. Data evaluated included baseline characteristics, treatment exposure, and efficacy outcomes [overall survival (OS) and time to progression (TTP)] of patients treated with abiraterone acetate plus prednisone or prednisolone (collectively, "abiraterone"), enzalutamide, or docetaxel. Descriptive outcomes are reported from the overall patient population and subgroups of patients with baseline cardiovascular disease, diabetes mellitus, or visceral metastases. The treatment effects for time to progression were compared for the overall patient population. RESULTS: The study enrollment period lasted 2.5 years, and each patient was followed for a maximum of 3 years. A total of 1874 patients in the PCR had not received previous mCRPC treatment at baseline, although they had received androgen-deprivation therapy. Prevalent co-morbidities included cardiovascular disease in 65.4% and diabetes mellitus in 17.4% of patients. Baseline characteristics suggested that patients with more advanced disease received docetaxel treatment. In the overall patient population, the median time to progression with abiraterone, enzalutamide, and docetaxel as first-line mCRPC therapy was 9.6, 10.3, and 7.6 months, respectively, and median OS was 27.1, 27.1, and 27.9 months, respectively. Outcomes in the subgroups of patients with cardiovascular disease or diabetes mellitus were similar to those of the whole population in the analysis. As expected, patients with visceral metastases had shorter TTP and OS than patients in the overall population. CONCLUSIONS: This analysis shows, for the first time, the effectiveness in parallel of first-line abiraterone, enzalutamide, and docetaxel in mCRPC, including in patients with co-morbidities such as cardiovascular disease or diabetes mellitus or in patients with visceral metastases. These real-world findings from the PCR provide meaningful information to help manage mCRPC, particularly in patients under-represented in clinical studies.

BACKGROUND: Intermittent androgen deprivation (IAD) has received increasing attention; however, the current literature is still limited, especially in nonmetastatic prostate cancer (PCa), and the relative efficacy and safety benefits of IAD versus continuous androgen deprivation (CAD) remain unclear. OBJECTIVE: To add to the knowledge base regarding efficacy and potential benefits, including reduced side effects and improved quality of life (QoL), of IAD versus CAD in patients with nonmetastatic relapsing or locally advanced PCa. DESIGN, SETTING, AND PARTICIPANTS: A 42-mo phase 3b open-label randomised study in 933 patients from 20 European countries. INTERVENTION: Following a 6-mo induction with leuprorelin acetate (Eligard) 22.5mg 3-mo depot, patients were randomised to CAD or IAD with leuprorelin for 36 mo. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary end point was time to prostate-specific antigen (PSA) progression while receiving luteinising hormone-releasing hormone agonist, defined as three consecutive increasing PSA values ≥ 4 ng/ml ≥ 2 wk apart. Secondary end points included PSA progression-free survival (PFS), overall survival (OS), testosterone levels, performance status, and QoL. RESULTS AND LIMITATIONS: A total of 933 patients entered the induction phase; 701 were randomised. The median number of injections administered after randomisation was 12 (range: 1-12) for the CAD group and 3 (range: 1-10) for the IAD group. There were no statistically significant or clinically relevant differences between the groups for time to PSA progression, PSA PFS, OS, mean PSA levels over time, or QoL. A similar number of adverse events was observed in each group; the most common were hot flushes and hypertension. Study limitations include the open-label design and absence of formal testosterone recovery assessment. CONCLUSIONS: IAD and CAD demonstrated similar efficacy, tolerability, and QoL in men with nonmetastatic PCa. The principal benefit of IAD compared with CAD is a potential cost reduction with comparable OS rates. There are no apparent QoL benefits. PATIENT SUMMARY: This randomised trial showed that both intermittent and continuous hormone therapy had similar efficacy, tolerability, and quality-of-life profiles in patients with relapsing M0 or locally advanced prostate cancer. Intermittent therapy may be a valid option for selected patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT00378690.
