A Study to Evaluate the Effect of Multiple Doses of JNJ-56021927 on the Pharmacokinetics of Multiple Cytochrome P450 and Transporter Substrates in Participants With Castration-Resistant Prostate Cancer

Inclusion Criteria: * Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2 * Adenocarcinoma of the prostate * Participants with non-metastatic castration-resistant prostate cancer (NM-CRPC) or metastatic castration-resistant prostate cancer (mCRPC), who in the opinion of the investigator may benefit from treatment with JNJ-56021927 * Surgically or medically castrated, with testosterone levels of \<50 nanogram per deciliter (ng/dL) * If the participant is being treated with a gonadotropin-releasing hormone (GnRHa) (ie, participant who has not undergone bilateral orchiectomy), then this therapy must have been initiated at least 4 weeks prior to the Cycle 1 Day 1 visit and must be continued throughout the study * Adequate bone marrow and organ function defined as: Hemoglobin (\>=9.0 g/dL, independent of transfusion or growth factor support within the prior 7 days); Absolute neutrophil count (\>=1000/mm\^3 independent of growth factor support within the prior 7 days); Platelet count (\>=75,000/mm\^3 independent of transfusion or growth factor support within the prior 7 days); Serum albumin (\>=3.0 g/dL); Serum creatinine (\<=1.5\*upper limit of normal (ULN) or calculated creatinine clearance \>=50 mL/min/1.73m\^2); Total bilirubin \[\<1.5\*ULN (participants with Gilbert's Syndrome may be enrolled if the total bilirubin is \<4 mg/dL with predominance of indirect bilirubin \>=80% of total bilirubin\]); Aspartate aminotransferase or alanine aminotransfer…
