Conditions
Brief summary
This study will assess the safety and tolerability of RO7049389 compared to placebo in single- and multiple-ascending doses in healthy Chinese participants.
Interventions
RO7049389 will be administered orally either as a single dose (SAD) or as multiple doses defined by the SAD portion of the study (MAD).
Placebo will be administered orally at a dose and frequency matched to RO7049389.

Outcome results
Percentage of Participants With Adverse Events
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Time frame: From the date of first administered dose through 28 days after the last administered dose.
Population: All safety analyses were based on the safety analysis population, which included all subjects that received at least one dose of study medication (RO7049389 or placebo), with at least one safety assessment.
