Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Part 1: SAD/FE
There will be 7 cohorts in this study.
In each cohort, participants will receive a single oral dose of RO6953958 while fasted.
Participants in the fed (FE) cohort will return to receive the same single oral dose of RO6953958 repeated in the fed state.
|
Part 1: RO6953958 will be administered in an adaptive manner. The starting dose is planned to be 5 milligrams (mg). Part 2: The starting dose is planned to be 45 mg. Part 3: RO6953958 will be administered QD following a standardized breakfast on Day 3 to Day 14 at the maximum dose QD that was tested in the ongoing Part 2 (MAD). |
PLACEBO_COMPARATOR: Part 1: SAD placebo
There will be 7 cohorts in this study.
In each cohort, participants will receive a single oral dose of a placebo while fasted/fed.
|
Part 1: A placebo will be administered in an adaptive manner. The starting dose is planned to be 5 mg. Part 2: The starting dose is planned to be 45 mg. |
EXPERIMENTAL: Part 2: MAD
A maximum of 5 dose levels are anticipated.
For each dose level, a minimum of 8 and a maximum of 16 participants will receive a multiple oral dose of RO6953958 once daily (QD) for 10 days.

PLACEBO_COMPARATOR: Part 2: MAD placebo
A maximum of 5 dose levels are anticipated.
For each dose level, a minimum of 8 and a maximum of 16 participants will receive a multiple oral dose of RO6953958 QD for 10 days.
|
Part 1: A placebo will be administered in an adaptive manner. The starting dose is planned to be 5 mg. Part 2: The starting dose is planned to be 45 mg. |
EXPERIMENTAL: Part 3: DDI
RO6953958 will be administered at the maximum dose QD that was tested in the ongoing Part 2 (MAD). Participants will also be administered midazolam. |
Part 1: RO6953958 will be administered in an adaptive manner. The starting dose is planned to be 5 milligrams (mg). Part 2: The starting dose is planned to be 45 mg. Part 3: RO6953958 will be administered QD following a standardized breakfast on Day 3 to Day 14 at the maximum dose QD that was tested in the ongoing Part 2 (MAD).
Midazolam will be administered as single intervenous (IV) bolus injection of 100 micrograms (ug) on Day 1 and Day 13, and as single oral dose of 300 ug on Day 2 and Day 14.
