Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With On-Treatments Adverse Events, Serious Adverse Events, and Deaths	The distribution of adverse events was done via the analysis of frequencies for Adverse Event (AEs), Serious Adverse Event (SAEs) and Deaths, through the monitoring of relevant clinical and laboratory safety parameters.	From study treatment start date till 30 days safety follow-up, assessed for up to 4 months
Secondary	Part A - Pharmacokinetic of KAE609: Maximum Observed Plasma Concentration (Cmax)	Venous whole blood samples were collected for activity-based pharmacokinetics characterization. Cmax was calculated from plasma concentration-time data using non-compartmental methods and summarized using descriptive statistics.	Day 1 (-1 hr, 2 min, 10 min, 30 min, 1 hr, 3 hr, 6 hr, 12 hr)
