    Time frame: Screening up until 28 days after the last dose of study drug (up to 1 year).

    An Adverse Event (AE) is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product, any new disease or exacerbation of an existing disease, recurrence of an intermittent medical condition, any deterioration in a laboratory value or other clinical test or adverse events that are related to a protocol-mandated intervention, including those that occur prior to assignment of study treatment.

Secondary outcomes

    Time frame: SAD: Pre-dose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36, 48 hours (h) Post-dose Days 1, 2; MAD: Pre-dose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24h Post-dose Days 1, 2 and Days 13, 14; Pre-dose, 2, 6, 24hr Post-dose Days 3, 5, 7, 9 and 11.

    Non-compartmental analysis using WinNonlin software was used to calculate PK parameters where appropriate. Summary descriptive statistics (Arithmetic Mean and Standard Deviation) for Cmax will be presented by treatment arm. Where appropriate, data maybe pooled and analyzed. Please note that this Outcome Measure was not measured for the Placebo Cohorts and SAD Cohorts (1-4) (on Day 13).

Summary descriptive statistics (Arithmetic Mean and Standard Deviation) for Renal Clearance will be presented by treatment arm. Where appropriate, data maybe pooled and analyzed. Please note that this Outcome Measure was not measured for the Placebo Cohorts and MAD Cohorts (1-4). Due to insufficient urine concentration data for RO7020531 and RO7033805, Renal Clearance for these 2 compounds could not be estimated.
