Brief Summary

The study is a Phase I, randomized double-blind, placebo-controlled, single and multiple dosing, dose-escalation study of the oral administration of DDN-A-0101 in healthy adults and elderly subjects

Detailed Description

The study includes two Parts; Part1 includes single ascending dose study (SAD) and Part2 includes multiple ascending dose study (MAD). Approximately 50 subjects will be enrolled in the SAD and MAD respectively. New subjects will be recruited for each cohort in both Parts. The SAD Part will include 5 dose levels (S1, S2, S3, S4, S5) and cohort S3 will proceed to food effect cohort. The MAD Part will include 5 dose levels (M1, M2, ME, M3, M4) and cohort ME will be performed in the elderly group.
