Study to find out whether treatment with orteronel plus prednisone has any potential effects on the heart, by looking at certain heart waves, called QT waves, using an electrocardiogram (ECG) machine.

- Primary Outcome Measures
Name Time Method Main Objective: To evaluate the effects of orteronel, when administered with prednisone, on the QT/QTc interval in patients with metastatic castration-resistant prostate cancer (mCRPC);Secondary Objective: To continue to assess the safety and pharmacokinetics of orteronel, when administered with prednisone, in patients with mCRPC;Primary end point(s): The primary endpoint is the change from baseline in QTc, based on the QTc with Fridericia correction (QTcF) method;Timepoint(s) of evaluation of this end point: Cycle 1 Day 1 through Cycle 2 Day 1 [study Day 29 +/- 1 day]<br>
- Secondary Outcome Measures
Name Time Method Secondary end point(s): The secondary endpoints include:<br>- Change from baseline in QTc with Bazett correction (QTcB), PR and QRS intervals, and uncorrected QT interval<br>-Change from baseline in HR<br>-Change from baseline in ECG morphology<br>-PK parameters for orteronel, including AUC from 0 to 6 hours (AUC0-6hr), Cmax, and first time to maximum plasma concentration (Tmax)<br>-Correlation between the QTcF change from baseline and plasma concentrations of orteronel<br>-Rates of AEs and serious adverse events (SAEs), changes in clinical laboratory values, vital sign measurements, physical examination findings, and ECG results;Timepoint(s) of evaluation of this end point: Cycle 1 Day 1 through Cycle 2 Day 1 [study Day 29 +/- 1 day]
