Design outcomes

Primary

MeasureTime frame
1. Maximum observed plasma concentration (Cmax) of RO7269162 determined using blood samples collected at pre-dose and multiple time-points post-dose from Day 1 up to Day 7 of Period 1 and Day 1 up to Day 14 of Period 2 2. Time to maximum plasma concentration (Tmax) of RO7269162 determined using blood samples collected at pre-dose and multiple time-points post-dose from Day 1 up to Day 7 of Period 1 and Day 1 up to Day 14 of Period 2 3. Area under the plasma concentration-time curve from time zero up to the last measurable concentration (AUClast) of RO7269162 determined using blood samples collected at pre-dose and multiple time-points post-dose from Day 1 up to Day 7 of Period 1 and Day 1 up to Day 14 of Period 2 4 Area under the plasma concentration-time curve from time zero extrapolated to infinity (AUCinf) of RO7269162 determined using blood samples collected at pre-dose and multiple time-points post-dose from Day 1 up to Day 7 of Period 1 and Day 1 up to Day 14 of Period 2

Secondary

MeasureTime frame
1. Number of participants with adverse events (AEs) and severity of AEs determined according data captured on the electronic case report forms (eCRF) from Screening to Follow-up (up to approximately 9 weeks) 2. Plasma Concentration of itraconazole determined using blood samples collected at pre-dose and multiple time-points post-dose from Day -3 to Day 14 of Period 2
