Outcome Measures

Primary Outcomes (2)

  • Percentage of Brain Alpha5-Containing GABA-A Receptors Occupied by RO7017773

    Baseline up to 48 hours (hrs)

  • Plasma Concentrations of RO7017773

    Baseline up to 48 hrs

Secondary Outcomes (1)

  • Number of Participants With Adverse Events (AEs)

    From treatment initiation until 14 days after the last dose of study treatment.

Study Arms (1)

RO7017773

EXPERIMENTAL

The first two participants of the first cohort are anticipated to receive a single dose of RO7017773 orally. The doses to be tested in the subsequent cohorts of participants will be determined by review of PET scan, PK, and safety results from the previous dose level.

Drug: RO7017773Other: [11C] Ro15-4513

Interventions

RO7017773 will be administered orally. The doses to be tested will be determined by review of PET scan, PK, and safety results from the previous dose level.

RO7017773

At the start of each PET scan, participants will receive an intravenous dose of the radiolabeled tracer \[11C\]Ro15-4513.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Healthy (absence of evidence of any active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead ECG, hematology, blood chemisty, serology, and urinalysis), as judged by the Investigator.

  • Abnormal pulse rate, resting pulse rate greater than 100 or less than 40 bpm
  • History or presence of clinically significant ECG abnormalities before study drug administration or cardiovascular disease
  • Show evidence of human immunodeficiency virus (HIV) infection and/or positive human HIV antibodies
  • Positive result on hepatitis B (HBV) or hepatitis C (HCV), presence of hepatitis B surface antigen (HBsAg) or positive hepatitis C antibody test result at screening or within 3 months prior to starting study treatment
