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).
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.

| JNJ 56021927 | Drug | JNJ 56021927 will be administered once daily orally in a dose of 240 mg from Study Day 15 up to disease progression, unacceptable toxicity, withdrawal of consent, lost to follow-up, the participant is no longer receiving clinical benefit in the opinion of the Investigator, the start of subsequent anticancer therapy, or the Sponsor ends the study. |
| Measure | Description | Time Frame |
|---|---|---|
| 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 |
| 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. AUC (0-last) 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 |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC(last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. AUC[0-infinity]) 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 |
| Measure | Description | Time Frame |
|---|---|---|
| Time to Reach Maximum Observed Plasma Concentration (Tmax) | The Tmax is defined as actual sampling time to reach maximum observed analyte concentration. Tmax for Midazolam, S-warfarin, omeprazole, fexofenadine, pioglitazone, rosuvastatin will be assessed along with the metabolites of Midazolam, S-warfarin, omeprazole and pioglitazone. | Days 1, 8, 9, 43, 50, and 51 |

| Drug Cocktail | Drug | Drug cocktail comprise of midazolam (2 mg), warfarin (10 mg), vitamin K (10 mg), omeprazole (40 mg), and fexofenadine (30 mg) will be administered on Study Day 1 and 43. |
|
| Pioglitazone | Drug | Pioglitazone 15 mg will be administered orally on Study Day 8 and 50. |

|
| Elimination Rate Constant (Lambda[z]) | Lambda(z) is first-order elimination rate constant associated with the terminal portion of the curve, determined as the negative slope of the terminal log-linear phase of the drug concentration-time curve. Lambda[z]) 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 |
| Elimination Half-Life (t1/2) | The elimination half-life (t1/2) is the time measured for the plasma concentration to decrease by 1 half to its original concentration.
