NCT04075266

Brief Summary

This 2-year study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic (PD) effects of ocrelizumab in children and adolescents ages ≥ 10 to ≤ 18 years with relapsing-remitting multiple sclerosis (RRMS). The data from this study will serve to determine the dosing regimen of ocrelizumab to be further investigated in the subsequent Phase III study in children and adolescents.

Outcome Measures

Primary Outcomes (3)

  • Dose Exploration Period: Area Under the Concentration Versus Time Curve of Ocrelizumab

    The population PK model was used to simulate concentration-time course and predict individual area under the concentration versus time curve. The data for the PK parameter: area under the concentration versus time curve was collected and analyzed as per body weight range (\<40kg to ≥40 kg).

    Pre-dose 5- 30 minutes and post-dose 30 mins on Days 1, 15 and 169; At any time on Days 29, 57, 85 and 113

  • Dose Exploration Period: Maximum Concentration (Cmax) of Ocrelizumab

    The population PK model was used to simulate concentration-time course and predict individual Cmax. The data for the PK parameter: Cmax was collected and analyzed as per body weight range (\<40kg to ≥40 kg).

    Pre-dose 5- 30 minutes and post-dose 30 mins on Days 1, 15 and 169; At any time on Days 29, 57, 85 and 113

  • Dose Exploration Period: Levels of CD 19+ B-cell Count in Blood

    At Week 24

Secondary Outcomes (17)

  • Number of Participants With Adverse Events (AEs)

    Up to 7 years

  • Dose Exploration Period: Level of Circulating T Cells and Natural Killer (NK) Cells

    At Week 24

  • OOE Period: Level of Circulating T Cells and NK Cells

    Up to 5 years

  • Dose Exploration Period: Level of Circulating Lymphocyte, Neutrophil, Monocyte and Leukocyte

    At Week 24

  • OOE Period: Level of Circulating Lymphocyte, Neutrophil, Monocyte and Leukocyte

    Up to 5 years

  • +12 more secondary outcomes

Study Arms (4)

Cohort 1

EXPERIMENTAL

Participants with a body weight from \>/= 25 kg to \< 40 kg (with at least 2 participants with a body weight from \>/= 25 kg to \</= 35 kg) will receive 300 milligram (mg) ocrelizumab

Drug: Ocrelizumab

Cohort 2

EXPERIMENTAL

Participants with a body weight \>/= 40 kg (with at least 2 participants with a body weight \>/= 40 kg but \</= 50 kg) will receive 600 mg ocrelizumab

Drug: Ocrelizumab

Cohort 3 (optional)

EXPERIMENTAL

Based on PK, PD, safety, and tolerability data analyses of Cohorts 1 and 2, additional participants with a body weight from \>/= 25 kg to \< 40 kg may be enrolled and receive another dose level of ocrelizumab

Drug: Ocrelizumab

Cohort 4 (optional)

EXPERIMENTAL

Based on PK, PD, safety, and tolerability data analyses of Cohorts 1 and 2, additional participants with a body weight \>/= 40 kg may be enrolled and receive another dose level of ocrelizumab

Drug: Ocrelizumab

Interventions

Ocrelizumab is administered as two infusions of half the dose given 14 days apart for the first dose, then subsequent doses are administered as a single infusion every 24 weeks. Cohort 1: total dose of 300 mg Cohort 2: total dose of 600 mg Cohort 3 and 4: additional dose level(s) may be lower than 300 mg, between 300 mg and 600 mg, or higher than 600 mg, but will be no higher than 1200 mg

  • Infection requiring hospitalization or treatment with IV anti-infective agents
  • History or known presence of recurrent or chronic infection (e.g., HIV, syphilis, tuberculosis)
  • Receipt of a live or live-attenuated vaccine within 6 weeks prior to treatment allocation

  • History of a severe allergic or anaphylactic reaction to humanized or murine monoclonal antibody (mAbs) or known hypersensitivity to any component of ocrelizumab solution
  • Previous treatment with B-cell-targeted therapies
  • Percentage of CD4 \< 30%
  • Absolute Neutrophil Count \< 1.5x1000/microliter
  • Lymphocyte count below the lower limit of normal (LLN) for age- and sex-specific reference range
