Even with first line therapy (ADT +/- docetaxel or abiraterone, based on the LATITUDE and STAMPEDE studies presented this week), most patients with metastatic hormone-sensitive prostate cancer (mHSPC) progress to castration-resistant prostate cancer (CRPC).

ASCO 2017: PROfound: A randomized Phase III trial evaluating olaparib in patients with metastatic castration-resistant prostate cancer and a deleterious homologous recombination DNA repair aberration

Details

At the 2017 ASCO prostate cancer poster session, Dr. Johann De Bono and colleagues presented their phase III trial design for PROfound, an evaluation of olaparib in patients with mCRPC and a deleterious homologous recombination DNA repair aberration. There are available agents that may be offered with limited therapeutic benefit for these patients, however no molecularly stratified treatment has been approved for this heterogeneous disease.

ASCO 2017: A phase III trial comparing atezolizumab with enzalutamide vs enzalutamide alone in patients with metastatic castration-resistant prostate cancer

Details
Chicago, IL (UroToday.com) Selecting the appropriate sequence and combination of therapy for metastatic castration-resistant prostate cancer (mCRPC) is challenging. At the ASCO 2017 prostate cancer poster session, Dr. Thomas Powles and colleagues presented their study design for a phase III trial comparing atezolizumab with enzalutamide versus enzalutamide alone in patients with mCRPC (IMbassador250 Trial).

ASCO 2017: Androgen deprivation therapy in the treatment of prostate cancer and dementia risk: A systematic review and meta-analysis

Details
Chicago, IL (UroToday.com) Since the introduction of the concept of castration as a treatment for advanced or metastatic prostate cancer (PCa) by Huggins & Hodges in 1941, castration and subsequently androgen deprivation therapy (ADT) have remained the standard first-line therapy for metastatic PCa.

ASCO 2017: Clinical activity and safety of ASN001, a selective CYP17 lyase inhibitor, administered without prednisone in men with metastatic castration-resistant prostate cancer (mCRPC): A phase 1/2 clinical trial

Details
Chicago, IL (UroToday.com) Abiraterone acetate, a CYP17A inhibitor, is now a well-established treatment option for metastatic castration-resistant prostate cancer (mCRPC), regardless of prior docetaxel chemotherapy treatment, based on the results of the COU-AA-301 and COU-AA-302. studies.1,2 However, abiraterone administration was approved along with the administration of prednisone 5 mg twice daily, due to the risk of mineralocorticoid excess from suppression of the glucocorticoid synthesis.

ASCO 2017: Prostate cancer in 696 hypogonadal men with and without long-term testosterone therapy: Results from a controlled registry study

Details
Chicago, IL (UroToday.com) The endocrinology relationship between testosterone and prostate cancer (PCa) is well-established, however whether men with hypogonadism have increased prostate cancer incidence or severity is controversial. Dr. Ahmad Haider and colleagues from Germany presented their results of assessing prostate cancer outcomes among men on long-term testosterone therapy (TTh) at the 2017 ASCO annual meeting’s prostate cancer poster session.

ASCO 2017: Phase 1b/2 keynote-365 trial: Pembrolizumab (pembro) combination therapy in metastatic castration-resistant prostate cancer

Details
Chicaco, IL (UroToday.com) Dr. Evan Yu and colleagues presented their trial design for KEYNOTE-365, a phase Ib/II trial assessing pembrolizumab combination therapy for metastatic castration-resistant prostate cancer (mCRPC) at the prostate cancer sessions at the 2017 ASCO annual meeting. We know that approved treatments for mCRPC (eg, enzalutamide and docetaxel) may increase programmed death ligand 1 (PD-L1) expression and facilitate neoantigen release. Furthermore, olaparib, a PARP inhibitor, has shown activity in mCRPC with DNA-repair defects. The objective of this study is to evaluate the safety and efficacy of pembrolizumab with olaparib (cohort A), docetaxel + prednisone (cohort B), or enzalutamide (cohort C) in mCRPC patients.

Details
Chicago, IL (UroToday.com) Abiraterone acetate, a CYP17A inhibitor, is now a well-established treatment option for metastatic castration-resistant prostate cancer (mCRPC), regardless of prior docetaxel chemotherapy treatment, based on the results of the COU-AA-301 and COU-AA-302 studies.1,2 Enzalutamide, a novel androgen axis inhibitor, was introduced as a treatment for mCRPC around the same time, and has been a competitor in the same disease space.

ASCO 2017: Avelumab in metastatic castration-resistant prostate cancer (mCRPC)

Details
Chicago, IL (UroToday.com) Avelumab, an anti-PD-L1 antibody, is one of the novel immune checkpoint inhibitors generating so much interest in the field of cancer therapy. With growing evidence for its efficacy in multiple solid malignancies, including its recent approval for the treatment of metastatic bladder cancer, there is an effort to assess these agents in the setting of castration-resistant prostate cancer.

ASCO 2017: Assessment of quality of life, cognitive function and depression in a randomized phase II study of abiraterone acetate (ABI) plus prednisone (P) vs enzalutamide (ENZA) for metastatic castrate-resistant prostate cancer (mCRPC)

Details
Chicago, IL (UroToday.com) As enzalutamide (Enza) and abiraterone (Abi) have become mainstays of therapy for patients with metastatic castration-resistant prostate cancer (mCRPC), a difficult clinical question has always been how to sequence these medications. In this randomized phase II clinical study, the goal is to evaluate the clinical efficacy and side effects of sequencing these two medications.

ASCO 2017: Survival impact of initial local therapy selection for men under 60 with high risk prostate cancer

Details
Chicago, IL (UroToday.com) The impact of initial local therapy selection on survival for high-risk prostate cancer (PCa) patients remains uncertain, particularly in younger men who in general have an appropriate life-expectancy at the time of prostate cancer diagnosis. Dr. Adeel Kaiser and colleagues presented their results of a study assessing the impact of initial local therapy selection for men under 60 with high-risk prostate cancer at the prostate cancer poster sessions at the 2017 ASCO annual meeting. To minimize the competing risk of death, the authors chose a younger cohort to assess the impact of initial local therapy on survival.
