Condition(s) targeted: Healthy Male

Intervention: TC-5214 (Drug); Placebo comparator (Other); Moxifloxacin (Drug); Moxifloxacin placebo comparator (Other)

Phase: Phase 1

Status: Terminated

Sponsored by: AstraZeneca

Official(s) and/or principal investigator(s):

Summary

This is a two part study. Part A will determine the maximum tolerated dose of TC-5214 administered to healthy male subjects in single ascending oral doses. This part of the study will define the highest dose of TC-5214 to be administered in Part B. Part B of this study will investigate the effect of TC-5214 on the electrical activity of the heart following single oral administration. The study will be carried out healthy male subjects in a four period crossover study with TC-5214 compared to placebo and oral moxifloxacin as a positive control. The safety, tolerability and pharmacokinetics of TC-5214 will also be evaluated.

Clinical Details

Official title: A Single-centre, Randomised, Double-blind, Placebo Controlled Phase I Study in Two Parts: Part A to Assess a Safe and Tolerable Supratherapeutic Dose of TC-5214 After Single Ascending Oral Doses in Healthy Male Subjects, Followed by Part B: A Four-period Double-dummy Crossover Study to Investigate the Effect of 2 Single Doses (Therapeutic and Supratherapeutic) of TC-5214 on the QT/QTc Interval, Compared to Placebo, Using Moxifloxacin (Avelox®) as a Positive Control, in Healthy Male Subjects

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Basic Science

Primary outcome:

Part A: To examine the safety and tolerability of TC-5214. The following assessments will be measured and reported: The number of participants with adverse events

Part A: To examine the safety and tolerability of TC-5214. The following assessments will be measured and reported: A change from baseline in laboratory assessments.

Part A: To examine the safety and tolerability of TC-5214. The following assessments will be measured and reported: A change from baseline in vital signs.

Part A: To examine the safety and tolerability of TC-5214. The following assessments will be measured and reported: A change from baseline in electrocardiogram (ECG).

Part A: To examine the safety and tolerability of TC-5214. The following assessments will be measured and reported: A change from baseline in physical examination.

Part B: The maximum mean change in time-matched ECG interval, measured from the onset of the QRS complex to the T point, using the best heart rate correction method (QTc).

Secondary outcome:

Part A: TC-5214 Plasma and urine pharmacokinetic variable to be measured: including, C max, time to C max, Area Under Curve (AUC) (0-t), terminal half life, cumulative amount of drug excreted unchanged into urine from zero to time and renal clearance

Part B: A change in the maximum of the mean change in time-matched ECG interval, measured from the onset of the QRS complex

Part B: Assay sensitivity by measuring the effect of moxifloxacin 400 mg on QTc compared to placebo

Eligibility

Minimum age: 18 Years. Maximum age: 50 Years. Gender(s): Male.

Criteria:

Inclusion Criteria:

repeated venipuncture

- Be able to understand and comply with the requirements of the study as judged by the

investigator Exclusion Criteria:

disorder which, in the opinion of the Investigator and Sponsor may either put the subject at risk because of participation in the study, or influence the results of the subject's ability to participate in the study

- History or presence of gastrointestinal (including irritable bowel disease), hepatic,

or renal disease or other condition known to interfere with the absorption, distribution, metabolism, or excretion of study drug. Subjects with a history of surgery on the gastrointestinal tract (not including appendectomy or cholecystectomy) should also be excluded
