  2. Time to Maximum Observed Plasma Concentration (Tmax) of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods.

  3. Apparent Clearance Following Extravascular Administration (CL/F) of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods.

  4. Apparent Volume of Distribution Following Extravascular Administration (Vd/F) of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods.

  5. Terminal Elimination Rate Constant (Lambda z) of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods.

  6. Terminal Elimination Half-Life (T1/2) Following Administration of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods.

  7. Time of Last Measurable Plasma Concentrations (Tlast) of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods.

  8. Percentage of AUC (0-Inf) Due to Extrapolation From the Time of the Last Observed Concentration (Tlast) to Infinity (%AUCex) of Depemokimab

    Timeframe: Day 1: Pre-dose and 2, 8 hours post-dose; Days 2, 3, 5, 8, 15, 29, 57, 85, 127, 169 and 183 post-dose

    Blood samples were collected at indicated time points for PK analysis of depemokimab. PK analysis was conducted using standard non-compartmental methods. The percentage of AUC (0-inf) obtained by extrapolation (%AUCex) was calculated as: (AUC\[0-inf\] - AUC\[0-t\]) /AUC(0-inf)\*100.

  9. Number of Participants With Presence of Positive Anti-depemokimab Antibodies

    Timeframe: Baseline (Day 1), Weeks 4, 8, 12 and 26

    Blood samples were collected and analyzed for the presence of anti- depemokimab antibodies using a validated immunoassay. The assay involved screening, confirmation and titration steps. If serum samples tested positive in the screening assay, they were considered 'potentially positive' and were further analyzed for the specificity using the confirmation assay. Samples that confirmed positive in the confirmation assay were reported as 'positive'. Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.

  10. Number of Participants With Positive Neutralizing Antibodies to Depemokimab

    Timeframe: Baseline (Day 1), Weeks 4, 8, 12 and 26

    Blood samples were collected for determination of positive neutralizing antibodies. A neutralizing antibody assay was performed. Neutralizing antibody test was only carried out for participants who have had a positive confirmatory binding antibody test result at visit. A participant was considered positive if they had at least one positive post-Baseline neutralizing antibody result. Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.
