Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ZKN-0013 is a modified macrolide
SAD cohorts:
• Cohort 1: ZKN-0013 15 mg or placebo orally once
• Cohort 2: ZKN-0013 50 mg or placebo orally once
• Cohorts 3 up to 7: dose levels to be determined based on Human PK modeling after SAD Cohorts 1 and 2

MAD cohorts
• Up to 7 cohorts: ZKN-0013 or placebo orally once daily for 15 days. Dose levels to be determined based on Human PK modeling after SAD Cohorts 1 and 2

Both ZKN-0013 and placebo will be administered as oral capsules.

Subjects will be randomized to receive single and then multiple doses of ZKN-0013 or placebo at a ratio of 3:1 in each cohort: Six subjects will receive ZKN-0013 and two will receive placebo.

Study drug administration will be recorded in each subject file to ensure compliance.
