| Change in Suicide Risk as Assessed Using the Columbia Suicide Severity Rating Scale (C-SSRS) | From screening visit through Period 2 Day 11 | The C-SSRS is an assessment tool to evaluate suicidal ideation and behavior. Categories have binary responses (yes/no) and include: Wish to be Dead; Non-specific Active Suicidal Thoughts; Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act; Active Suicidal Ideation with Some Intent to Act, without Specific Plan; Active Suicidal Ideation with Specific Plan and Intent, Preparatory Acts and Behavior; Aborted Attempt; Interrupted Attempt; Actual Attempt (non-fatal); Completed Suicide. Suicidal ideation or behavior is indicated by a yes answer to any of the listed categories. A score of 0 is assigned if no suicide risk is present. |

Outcome results
Maximum Concentration (Cmax) of RO7017773 in Plasma
Time frame: Period 1 (RO7017773) and Period 2 (RO7017773 + Itraconazole)
Population: The pharmacokinetic set (PKS) included all participants who received at least one dose of study treatment and who had data from at least one post-dose sample. This outcome measure is specific to the reported arms.
| Arm | Measure | Value (GEOMETRIC_MEAN) | Dispersion |
|---|---|---|---|
| RO7017773 Alone | Maximum Concentration (Cmax) of RO7017773 in Plasma | 458 ng/mL | Geometric Coefficient of Variation 32.1 |

Change in Suicide Risk as Assessed Using the Columbia Suicide Severity Rating Scale (C-SSRS)
The C-SSRS is an assessment tool to evaluate suicidal ideation and behavior. Categories have binary responses (yes/no) and include: Wish to be Dead; Non-specific Active Suicidal Thoughts; Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act; Active Suicidal Ideation with Some Intent to Act, without Specific Plan; Active Suicidal Ideation with Specific Plan and Intent, Preparatory Acts and Behavior; Aborted Attempt; Interrupted Attempt; Actual Attempt (non-fatal); Completed Suicide. Suicidal ideation or behavior is indicated by a yes answer to any of the listed categories. A score of 0 is assigned if no suicide risk is present.
Time frame: From screening visit through Period 2 Day 11
Population: The included set (IS) contained all study participants.
