Study Overview
=================
Brief Summary
-----------------
This was a randomized, subject and investigator-blinded, placebo-controlled, single and multiple ascending intravenous (iv) dose study in healthy subjects to assess the safety and tolerability of KAE609 given in the vein.

Detailed Description
-----------------
The study consisted of 2 parts: single-ascending dose (SAD) part and multiple ascending dose (MAD) part. In Part A (Single-ascending dose (SAD) part), it was planned to recruit 6 active, 2 placebo subjects in each cohort: Cohort A1: 10.5 mg/placebo Cohort A2: 30 mg/placebo Cohort A3: 75 mg/placebo Cohort A4: 120 mg/placebo Cohort A5: 210 mg/placebo In Part B (Multiple-ascending dose (MAD) part), Subjects were assigned to one of the following treatment arms in a ratio of 2:1 (6 active, 3 placebo): Cohort B1: 60 mg/placebo, every 24 hours (q24h) × 5 days Cohort B2: 120 mg/placebo, every 24 hours (q24h) × 5 days Eligible subjects were randomized to receive a single or q24h x 5 doses of either KAE609 or placebo. Safety, tolerability and pharmacokinetics were assessed over the period of 8 days for single dose and 12 days for multiple dose up to end of study visit for each subject.
