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.
