a single and multiple dose study of amaz-02 to evaluate safety and pharmacokinetics in elderly subjects

Conditions: Aging; Mitochondrial Dysfunction; Muscle Function

Summary: part a: the study is a double-blind, randomized, single ascending doses, study in 24 healthy elderly male and female volunteers. each subject will be randomized for two subsequent doses in three cohorts. part b: the study is a double-blind, randomized, multiple ascending doses study in 36 healthy elderly male and female volunteers. subjects will be randomized to receive study product or placebo for 28 days.

part a: single ascending dose study of amaz-02 with 3 cohorts (each cohort n=8 subjects, total n=24 subjects). cohorts undergo two periods of single dose intervention separated by 3 week washout. adverse events, clinical biochemistry for safety assessment and plasma and urine collected for pharmacokinetic measurement for parent and metabolite levels in circulation. part b: multiple ascending dose study with 3 cohorts (each cohort n=12 subjects, total n=36 subjects). 28 day administration with amaz-02 for safety, pk and pd assessment.
