Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) with Severity of AEs Measured According to National Cancer Institute Common Terminology Criteria for Adverse Events version 5 (NCI CTCAE v 5) [ Time Frame: Day 1 to Day 169 ]
  2. Percentage of Participants With Abnormal Laboratory Findings [ Time Frame: Day 1 to Day 169 ]
  3. Percentage of Participants With Abnormal Vital Signs and Electrocardiogram (ECG) Parameters [ Time Frame: Day 1 to Day 169 ]
  4. Change From Baseline in Suicide Risk as Assessed Using the Columbia-Suicide Severity Rating Scale (C-SSRS) [ Time Frame: Day 1 to Day 169 ]
    The C-SSRS is an interview-based instrument used to assess baseline incidence of suicidal ideation and behavior. The assessment includes "yes" or "no" responses for 5 questions, each related to suicidal ideation (wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods, active suicidal ideation with some intent, active suicidal ideation with specific plan) and suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, suicide). Numeric ratings are provided for severity of ideation (if present), from 0 to 5. A score of 0 is assigned if no suicide risk is present. A score of 1 or higher indicates suicidal ideation or behavior, with 5 being the most severe.

  4. Area Under the Serum Concentration-Time Curve up to the Last Measurable Concentration (AUClast) [ Time Frame: Predose and post dose at 0.5 hour, 1 hour (or end of infusion), 2 hour, 3 hour (or end of infusion), 8 hour on Day 1, and on Days 2, 3, 5, 8, 15, 22, 29, 57, 85, 113, 169 ]
  5. AUC From Time 0 to Infinity (AUCinf) [ Time Frame: Predose and post dose at 0.5 hour, 1 hour (or end of infusion), 2 hour, 3 hour (or end of infusion), 8 hour on Day 1, and on Days 2, 3, 5, 8, 15, 22, 29, 57, 85, 113, 169 ]
  6. Total Body Clearance (CL) Of RO7121932 [ Time Frame: Predose and post dose at 0.5 hour, 1 hour (or end of infusion), 2 hour, 3 hour (or end of infusion), 8 hour on Day 1, and on Days 2, 3, 5, 8, 15, 22, 29, 57, 85, 113, 169 ]
  7. Terminal Rate Constant of RO7121932 [ Time Frame: Predose and post dose at 0.5 hour, 1 hour (or end of infusion), 2 hour, 3 hour (or end of infusion), 8 hour on Day 1, and on Days 2, 3, 5, 8, 15, 22, 29, 57, 85, 113, 169 ]
  8. Apparent Terminal Half-Life (T1/2) of RO7121932 [ Time Frame: Predose and post dose at 0.5 hour, 1 hour (or end of infusion), 2 hour, 3 hour (or end of infusion), 8 hour on Day 1, and on Days 2, 3, 5, 8, 15, 22, 29, 57, 85, 113, 169 ]
  9. Cerebrospinal Fluid (CSF) Concentration of RO7121932 (Cohorts 5 and 6, and later cohorts, as appropriate) [ Time Frame: Day 1 to Day 169 ]
  10. Percentage of Participants With Anti-RO7121932 Antibodies [ Time Frame: Predose on Day 1, and on Days 8, 22, 29, 57, 85, 169 ]
  11. Time Course of B cells in Blood and CSF [ Time Frame: Day 1 to Day 169 ]
  12. Change From Baseline in B-cell count in Blood and CSF [ Time Frame: Day 1 to Day 169 ]
