A Thorough QT/QTc Study to Assess the Effects of Androxal in Healthy Male Subjects

NCT02117830 | Completed Phase 1

• 1 other identifier: ZA-108
• Study Type: interventional
• Target: 54
• Locations: 0 countries
• Sites: N/A

Brief Summary

This is a Phase I, single-site, randomized, double-blinded, double-dummy, placebo- and positive-controlled, 4-period crossover study to evaluate the effect of two dose levels of Androxal on cardiac repolarization. Baseline ECGs will be obtained prior to dosing in each Period and ECGs will be obtained during expected peak plasma concentrations of Androxal and the positive control. In each Treatment Period subjects will be admitted to a Clinical Research Unit where study drug will be administered as three (3) daily single doses. Treatment Periods will be separated by a washout of at least 7 days between Periods.

Outcome Measures

Primary Outcomes (1)

• The placebo-subtracted change of the QTc interval from Baseline (ΔΔQTc) defined as: the change of QTc from the subject-specific and period-specific Baseline (ΔQTc), less the time-matched placebo value of change of QTc

Eligibility Criteria

• Age: 18 Years - 60 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Generally healthy males as determined by history and physical examination
• Between the ages of 18 and 60, inclusive
• Clinical laboratory test results within the normal reference ranges for the investigative site or results with acceptable deviations that are judged by the principal investigator to be not clinically significant
• Vital signs (after 5 minutes resting in a supine position)
• Systolic blood pressure (SBP) 90-140 mmHg, and
• Diastolic blood pressure (DBP) 50-90 mmHg, and
• Pulse 45-100 bpm Note: subjects with vital signs outside the above ranges may be eligible for the study if the Investigator feels that the results are not clinically significant and will not impact study conduct.
• Body mass index (BMI) ≥25 to ≤42 kg/m2 at Screening
• Are reliable and willing to be available for the duration of the study, abiding by the policies and procedures of the clinical trials unit
• Have given written informed consent
• Subject must be able to speak, read and understand English or Spanish and be willing and able to provide written informed consent in English or Spanish on an Institutional Review Board (IRB)-approved form prior to the initiation of any study procedures. Subject must have signed and dated a written informed consent form (ICF) before undergoing any study related activities, including discontinuation of any prohibited medications.

You may not qualify if:

• Repros employee or investigative site personnel and their immediate families
• Participation in a clinical trial within the past 30 days or receipt of any investigational agent or study treatment within 30 days or 5 half-lives, whichever is longer, prior to Screening
• Known hypersensitivity to Clomid
• Known allergy to moxifloxacin
• Abnormal electrocardiogram that, after the option of repeating any such findings, in the opinion of the Investigator and/or Sponsor may interfere with any aspect of study conduct or interpretation of results including:
• an abnormality of cardiac rhythm other than sinus arrhythmia
• QTcF \> 450 msec
• QTcF \< 300 msec
• PR interval \>200 msec
• QRS \> 110 msec
• abnormal T wave morphology that will impair the ability to measure the QT interval reliably
• History of congenital long QT syndrome or known history of QTc interval prolongation or family history of congenital long QT syndrome
• Evidence of significant cardiac disease, for example, arrhythmia or unexplained syncope within the last year
• History of myocardial infarction, unstable angina, symptomatic heart failure, ventricular dysrhythmia,
• History of thrombophlebitis, thromboembolic disorder or cerebrovascular accident
