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. The study will consist of three parts (Part I, II, and III). At each dose level/cohort, a total of 8 healthy volunteers will be randomized to receive active study drug or placebo in a 3:1 ratio.

Study Arms (6)

Part I: RO7079901

EXPERIMENTAL

Participants will be randomized in two dose cohorts to receive single dose of RO7079901 1000 and 2000 milligrams (mg) intravenous (IV) infusion on Days 1 through Day 7 every 8 hours (q8h), for a total of 19 doses, with the last dose administered on the morning of Day 7.

Drug: RO7079901

Part I: Placebo

PLACEBO COMPARATOR

Participants will be randomized in two dose cohorts to receive single dose of placebo matching to RO7079901 on Days 1 through Day 7 q8h, for a total of 19 doses, with the last dose administered on the morning of Day 7.

Other: RO7049389 Placebo

Part II - Single Dose and Repeat Dose: RO7079901

EXPERIMENTAL

Participants will be randomized in two dose cohorts to receive single dose of RO7079901 IV infusion at a dose above the previously studied dose levels in Part I (greater than \[\>\] 2000 mg) on Day 1, with the option to extend to q8h dosing for 7 days (i.e., starting on Day 3 through Day 9); once PK, safety and tolerability have been confirmed up to 48 hrs after the single dose.

Drug: RO7079901

Part II - Single Dose and Repeat Dose: Placebo

PLACEBO COMPARATOR

Participants will be randomized in two dose cohorts to receive single dose placebo matching to RO7079901 on Day 1, with the option to extend to q8h dosing for 7 days (i.e., starting on Day 3 through Day 9); once PK, safety and tolerability have been confirmed up to 48 hrs after the single dose.

Other: RO7049389 Placebo

Part III: RO7079901 + Meropenem

EXPERIMENTAL

Participants will be randomized in three dose cohorts to receive RO7079901 and Meropenem IV infusion in one of the 2 treatment sequences. Participants randomized to Sequence 1 will receive a single dose of 2000 mg meropenem IV infusion on Day 1. On Day 2, participants will receive a single dose of RO7079901 IV infusion. Participants randomized to Sequence 2 will receive a single dose of RO7079901 IV infusion on Day 1. On Day 2, participants will receive a single dose of 2000 mg meropenem IV infusion. Starting on Day 3 and continuing through Day 9 (i.e., for a total of 19 doses, last dose in the morning of Day 9) all participants will receive RO7079901 in combination with meropenem IV infusion q8h, regardless of sequence. Escalation to a maximum dose of RO7079901 5000 mg q8h may be considered on the basis of safety and tolerability data from the previous cohorts.
