Clinical Trial Summary

The purpose of this study is to evaluate the effects of repeat dosing of JNJ-56021927 on the pharmacokinetics for single-dose multiple cytochrome P450 (CYP450) enzymes (CYP3A4, CYP2C9, CYP2C19, CYP2C8) and transporter (P-gp and BRCP) substrates in participants with castration-resistant prostate cancer (CRPC).

Description:

This is a Phase 1, multicenter, open-label study in participants with CRPC. The study will consist of a Screening Phase to determine eligibility, a Pretreatment Phase, a Treatment Phase, and a Follow-up Phase. The study is designed to estimate the magnitude of the effects of JNJ-56021927 on the pharmacokinetics of probe substrates. In vitro studies have indicated that JNJ-56021927 and its active metabolite JNJ-56142060 (M3) have the potential to affect multiple cytochrome P450 (CYP) enzymes (CYP3A4, CYP2C9, CYP2C19, and CYP2C8) and drug transporters proteins (P-glycoprotein [P-gp] and breast cancer resistance protein [BRCP]) via inhibition or induction. In human hepatocytes, JNJ 56021927 and JNJ-56142060 (M3) were found to be inducers of CYP3A4. The induction of CYP3A4 suggests that JNJ-56021927 and M3 will induce other CYP isozymes and drug transporters (eg, CYP2C and P-gp via activation of pregnane X receptor). The study is designed to confirm the in vivo significance of these non-clinical findings.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Observed Plasma Concentration (Cmax)	Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve. Cmax for Midazolam, S-warfarin, omeprazole, fexofenadine, pioglitazone, rosuvastatin will be assessed along with the metabolites of Midazolam, S-warfarin, omeprazole and pioglitazone.	Day 1, 8, 9, 43, 50, and 51
Primary	Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Time (AUC [0-last])	The AUC (0-last) is the area under the plasma concentration-time curve from time zero to last quantifiable time.
