Brief summary
A multi-center, randomized, open-label, parallel-group, repeat dose study in asthma patients with elevated eosinophils. Eligible subjects will receive 3 doses (28 days apart) of mepolizumab given intravenous (IV) or subcutaneously (SC). Blood samples for safety, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity analysis, as well as safety/tolerability assessments will be collected throughout the study
Detailed description
Mepolizumab (SB-240563) is a humanized monoclonal antibody that blocks human interleukin 5 (IL-5) from binding to its receptor. Mepolizumab is currently under development for severe refractory asthma and a Phase IIB dose-ranging study using the IV route of administration is currently on-going. This study will be a multi-center, randomized, open-label, parallel-group, repeat dose study conducted in approximately 65 subjects with established asthma and elevated blood eosinophil levels. Dosing will occur on three occasions, every four weeks \[Day 1, Day 28 (+/- 3 days) and Day 56 (+/- 3 days)\]. Blood samples for safety, pharmacodynamics (PD), pharmacokinetics (PK) and immunogenicity analysis, as well safety and tolerability assessments will be collected/assessed throughout the study. Each subject will participate in the study for up to approximately 22 weeks, including screening, dosing and follow-up.

| Terminal Half-life (t½) From Pre-dose (Day 1) to Day 140 for Mepolizumab | Days 1, 3, 7, 28, 56, 70, 84, 112 and 140 | Terminal half-life (t1/2) was estimated by modelling techniques using non-linear mixed effect methods for the individual and population pharmacokinetic parameters for mepolizumab from the sparse sampling. Blood samples for PK analyses of mepolizumab were collected on dosing days (Days 1, 28 and 56) at pre-dose and 0.5 h, 1 h and 2 h post-dose (time was relative to the end of infusion in the IV cohort) as well as on Days 3, 7, 70, 84, 112 and 140 (follow-up visit). |
| Change From Baseline in Blood Eosinophil Levels at Week 12 (Day 84) | Baseline (Day 1 pre-dose) and Week 12 | Change from Baseline in blood eosinophils was calculated as the post-Baseline value minus the Baseline value. The change from Baseline in log-transformed blood eosinophil levels at Week 12 was analyzed using both a linear and non-linear (Imax) dose response models. The dose response was found to be non-linear and hence only the results of the non-linear model are presented. Mepolizumab 75mg IV assumed to equate to 100 mg SC within model. Prior to log10-transformation, zero values were imputed with half the minimum value across all dose groups and time points. An adjustment for Baseline eosinophil count was also incorporated into the model. |
| Area Under the Blood Eosinophil Time Curve (AUEC) up to Day 84 | Days 1, 3, 7, 28, 56, 70 and 84 | Area under the absolute blood eosinophil time curve to Day 84 (AUECeos\[0-day 84\]) determined using the linear trapezoidal rule for subset of participants with blood eosinophil data to Day 84. Blood samples for the analyses of AUEC(eos) (0-day 84) were collected at Days 1, 3, 7, 28, 56, 70 and 84. |
| Maximum Change From Baseline in Blood Eosinophils (Emax) | Days 1, 3, 7, 28, 56, 70, 84, 112 and 140 | Blood samples were collected at Days 1, 3, 7, 28, 56, 70, 84, 112 and 140 to assess the maximum reduction from Baseline in blood eosinophils between Day 1 pre-dose and last quantifiable study measurement.

Primary
Mean Area Under the Plasma-concentration Time Curve (AUC) Following SC and IV Administration of Mepolizumab
AUC of mepolizumab was estimated by population modeling techniques using non-linear mixed effect methods for the individual and population pharmacokinetic parameters from the sparse sampling. Individual cumulative plasma of mepolizumab AUC to Day 84 (cumAUC(0-day 84)), is the sum of the AUCs over each dosing interval after each of the three doses administered, for those participants with data up to Day 84. Individual cumulative plasma of mepolizumab AUC to Day 140 (cumAUC(0-day 140) is the sum of the AUCs over each dosing interval after each of the three doses administered plus the AUC post the last dose interval up to Day 140 (i.e. from Day 84 to Day 140). Blood samples for PK analyses were collected on dosing days (Days 1, 28 and 56) at pre-dose and 0.5 hour (h), 1 h and 2 h post-dose (time was relative to the end of infusion in the IV cohort) as well as on Days 3, 7, 70, 84, 112 and 140 (follow-up visit).

Mean AUC to Assess the Absolute Bioavailability of SC Mepolizumab
Population modelling techniques using non-linear mixed effect methods were used to estimate individual and population pharmacokinetic parameters from the sparse sampling. Log-transformed individual clearance estimates were analysed using an analysis of variance (ANOVA) model. The absolute bioavailability for each SC dose group and across SC doses will be estimated from the model together with associated 90% confidence intervals. Blood samples for PK analyses were collected on dosing days (Days 1, 28 and 56) at pre-dose and 0.5 h, 1 h and 2 h post-dose (time was relative to the end of infusion in the IV cohort) as well as on Days 3, 7, 70, 84, 112 and 140 (follow-up visit).

Mean Dose Normalized Cmax Ratio to Assess the Relative Bioavailability of SC Mepolizumab as Compared With IV Mepolizumab
Maximum plasma concentration was estimated by population modelling techniques using non-linear mixed effect methods for the individual and population pharmacokinetic parameters from the sparse sampling. Log-transformed dose-normalized (DM) Cmax were be analyzed using an analysis of variance (ANOVA) model. The ratio for each SC dose group versus IV and across SC doses versus IV will be estimated from the model together with associated 90% confidence intervals. Blood samples for PK analyses of mepolizumab were collected on dosing days (Days 1, 28 and 56) at pre-dose and 0.5 h, 1 h and 2 h post-dose (time was relative to the end of infusion in the IV cohort) as well as on Days 3, 7, 70, 84, 112 and 140 (follow-up visit).

Secondary
Number of Participants With Levels of Anti-mepolizumab Antibodies at Indicated Time Points
Blood samples were collected for the determination of anti-mepolizumab antibodies by antibody detection (AD) and antibody neutralisation (AN) assay. For participants who prematurely withdrew from the study and had been dosed, immunogenicity testing occurred (if possible) at the time of premature withdrawal and at 16 weeks after dosing (or the end of the study, whichever came first). Serum was tested for the presence of anti-mepolizumab antibodies using the currently approved analytical methodology incorporating screening, confirmation and titration steps. Samples confirmed positive for the presence of anti-mepolizumab antibodies in the original assay were tested for the presence of neutralizing antibodies.
Time frame: Day 1, Day 112 and Day 140
Population: Safety Population. Only those participants available at the indicated time points were analyzed (represented by n=X, X, X, X in the category titles).
