Brief summary
Perhexiline is the study drug that is being developed by Heart Metabolics, Ltd to potentially treat hypertrophic cardiomyopathy (HCM). HCM is a primary disease of the myocardium (the muscle of the heart) in which a portion of the myocardium is hypertrophied (thickened) without any obvious cause. The purpose of this study is to evaluate the effects of Perhexiline on heart conduction (the electrical activity of the heart) as compared to placebo (a tablet that will be made to look identical to the real drug but has no active ingredient) in healthy adult male and female volunteers. Moxifloxacin, also known as Avelox Registered Trademark', is a compound designed as an antibiotic that is indicated for the treatment of adults with infections. Moxifloxacin is known to have minor effects on heart conduction.
Interventions
This is a single study with 2 separate phases (as approved by an ethics committee). In the pilot phase of this study, a single cohort of 10 subjects will be dosed with open-label perhexiline oral tablets as follows: Day 1 and 2 - 200 mg every 12 hours, Day 3 and 4 - 200 mg once on each day, Day 5 - 150 to 300 mg (as guided by individual Perhexiline plasma levels) and Day 6 - 400 mg once. The Thorough QT (TQT) Phase of the study is blinded, randomized, placebo-controlled, parallel-arm design with a nested crossover comparison to moxifloxacin. Up to 100 subjects will participate in this phase, randomized in a 2:1:1 ratio into treatment assignments as listed below: Day -2 - Placebo Perhexiline (all 3 groups) Day -1 Placebo Moxifloxacin (Groups 1 and 2a), Moxifloxacin 400 mg (Group 2b) Days 1 to 6 - Perhexiline (Group 1), Placebo Perhexiline (Groups 2 a and 2b) Day 7 - Placebo Moxifloxacin (Groups 1 and 2b), Moxifloxacin (Group 2a) Dosing for Days 1 to 6 is as follows: Subjects Randomized to Perhexiline: Days 1 to 2 - 2 x 100 mg Perhexiline in the morning - 2 x 100 mg Perhexiline in the evening Days 3 to 4 - 2 x 100 mg Perhexiline in the morning - No evening dose Day 5 - Single dose of Perhexiline of between 150 and 300 mg, guided by subject's plasma Perhexiline level Day 6 - 4 x 100 mg Perhexiline in the morning - No evening dose Subjects Randomized to Placebo: Days 1 to 2 - 2 x 100 mg Placebo in the morning - 2 x 100 mg Placebo in the evening Days 3 to 4 - 2 x 100 mg Placebo in the morning - No evening dose Day 5 - 3 x 100 mg Placebo and 2 x 25 mg Placebo in the morning - No evening dose Day 6 - 4 x 100 mg Placebo in the morning - No evening dose On Day 7, all subjects will receive either Moxifloxacin 400 mg or Placebo, orally once. Subjects enrolled in both the Pilot Phase and the TQT Phase of the study will remain in the unit for the duration of the dosing period, and protocol compliance will be strictly adhered to.
