A Study to Investigate the Safety, Tolerability, and Pharmacokinetics of RO7079901 and the Combination of RO7079901 With Meropenem in Adult Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
This is a randomized, double-blind, placebo-controlled, multiple-ascending dose (MAD) study that will evaluate the safety, tolerability and pharmacokinetics (PK) of RO7079901 and the combination of RO7079901 with meropenem in healthy volunteers.
