Overview

Brief Summary

This is a Phase I, single-center, randomized, single-blind, placebo-controlled study in healthy subjects assessing the safety, tolerability and pharmacokinetic profile of three different dose levels of M6229 when administered continuously for 120 hours.

Detailed Description

Three dose levels of M6229 will be assessed in sequential study cohorts. Each cohort will consist of up to 3 male and 3 female subjects (2 male and 2 female subjects on M6229, 1 male and 1 female subject on placebo). Following a screening period of up to 28 days during which eligibility will be assessed, subjects will be randomized to M6229 or placebo and start a 120-hour continuous infusion on Day 1. Subjects will undergo safety assessments (incl. laboratory assessments) and pharmacokinetic sampling following a predefined schedule from Day 1 until Day 9. Subjects will be discharged on Day 9. The clinical study will be completed with an end-of-study visit, which will take place between 5 to 9 days after the last treatment-defined assessment.
