Prostate Cancer Clinical Trial

A JNJ-56021927 (ARN-509; Apalutamide) QT/QTc Study

Summary

The purpose of this study is to determine whether daily treatment with apalutamide affects the ventricular repolarization in participants with Castration-Resistant Prostate Cancer (CRPC)

Full Description

This is an open-label (a study in which the drug, procedure is known to participant and investigator), multicenter, Phase 1b study to investigate the effect of apalutamide on ventricular repolarization at a dose level of 240 milligram (mg daily). Approximately 42 participants with high-risk non-metastatic prostate cancer (NM-CRPC), defined as having a prostate specific antigen (PSA) doubling time less than or equal to (<=) 10 months, or participants with metastatic CRPC will be enrolled. The study consists of a 28-day Screening Phase, a Treatment Phase and a Follow-up Phase. In the Treatment Phase the study drug will be administrated in cycles of 28 days and the participants will be monitored for safety (including cardiac safety) and pharmacokinetics of the study drug. Adverse Events will be monitored throughout the study and in the Follow-up Phase until 30 days after the last dose of study drug. All participants will continue on study until disease progression, withdrawal of consent, lost to follow-up, the occurrence of unacceptable toxicity, the participant is no longer receiving clinical benefit in the opinion of the investigator, or termination of the study by the sponsor. Upon discontinuation of study drug, the participants will return for an End-of-Treatment (EoT) visit no later than 30 days after their last dose. The end of the study corresponds to the clinical cutoff and end of data collection.

Eligibility Criteria

Inclusion Criteria:

Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
Adenocarcinoma of the prostate; either non-metastatic castrate resistant prostate cancer (NM-CRPC) with high risk disease (defined as PSA Doubling time equal or less than (<=) 10 months) or metastatic CRPC
Be surgically or medically castrated with testosterone levels of less than (<) 50 nanogram per deciliter
If treated with a gonadotropin releasing hormone analog (ie, patient who has not undergone bilateral orchiectomy), then this therapy must have been initiated at least 4 weeks prior to Cycle 1 Day 1 and must be continued throughout the study
Electrocardiogram (ECG) showing a QT interval corrected for heart rate, using Fridericia formula (QTcF) <= 470 milliseconds (based on the average of a triplicate ECG set collected during the screening visit)
Left ventricular ejection fraction (LVEF) of more than 45% as determined by multiple uptake gated acquisition (MUGA) or echocardiography at the screening visit

Exclusion Criteria:

Abnormal cardiac function at screening
Known brain metastases
Has received an investigational drug within 4 weeks, or within a period < 10 times the drug's half-life, whichever is longer, of Cycle 1 Day 1
Has received chemotherapy or immunotherapy for the treatment of prostate cancer within 4 weeks of Cycle 1 Day 1
Prior treatment with enzalutamide and apalutamide
Use of therapies that must be discontinued or substituted within at least 4 weeks prior to Cycle 1 Day 1 including medications to lower seizure threshold, inducing/inhibiting metabolizing enzymes or prolonging the QT interval
History or condition that may predispose to seizures, or evidence of severe or unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events within 12 months prior to Cycle 1 Day 1, New York Heart Association (NYHA) Class II to IV heart disease
