Brief Summary:
This Phase IIa international multicenter, open-label, uncontrolled study will evaluate the safety and pharmacokinetics of rituximab (MabThera/Rituxan) in pediatric participants with severe granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA). Participants will receive rituximab 375 milligrams per square meter (mg/m^2) intravenously (IV) on Days 1, 8, 15 and 22.

Arm Intervention/treatment
Experimental: Rituximab Drug: Rituximab
Participants will receive rituximab 375 mg/m^2 IV infusion on Days 1, 8, 15 and 22. Rituximab infusions will be given at a rate of 25 milligrams per hour (mg/h). This may be escalated at a rate of 25 mg/h increments every 30 minutes to a maximum of 200 mg/h.

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), Including Serious AEs [ Time Frame: Baseline (Day 1) up to last visit (1.5-5 years) ]
    An AE is any unfavourable and unintended sign (including abnormal laboratory finding), symptom, or disease temporarily associated with the use of a study drug, whether or not considered related to the study drug. A SAE is any experience that results in death, is life-threatening, requires in-patient hospitalisation or prolongation of existing hospitalisation, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is medically significant.

  2. Pharmacokinetics: Rituximab Clearance (CL) [ Time Frame: From Day 1 to Day 180 ]

    CL is a quantitative measure of the rate at which a drug substance is removed from the body. The following allometric scaling equation was used for the estimation of CL in children:

    CL= qCL X (BSA/1.9) 0.92 X 1.31*ADA

    where qCL is a typical value of clearance in millilitres per day (mL/day) for a typical participant (i.e., Body Surface Area (BSA) of 1.9 m^2 and absence of anti-rituximab antibodies (ADA)) and is equal to 258 mL/day; BSA is in m^2 and ADA is 1 when anti-rituximab antibodies are present (0 otherwise). The allometric scaling factor was 0.92. CL was calculated in millilitres per day (mL/day).


  3. Pharmacokinetics: Volume of Distribution (Vd) of Rituximab [ Time Frame: From Day 1 to Day 180 ]
    Vd is defined as the theoretical central volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Vd was calculated in millilitres (mL).


Secondary Outcome Measures :
  1. Pharmacokinetics: Area Under the Concentration-Time Curve From Time 0 to 180 Days (AUC-180) of Rituximab [ Time Frame: From Day 1 to Day 180 ]
    The AUC0-180 is a measure of the plasma concentration of rituximab over time. The AUC0-180 was calculated in micrograms per millilitres times day (mcg/mL*day).

  2. Pharmacokinetics: Maximum Plasma Concentration (Cmax) of Rituximab [ Time Frame: From Day 1 to Day 180 ]
    Cmax is the maximum observed plasma rituximab concentration. Cmax was assessed at each visit following 1st, 2nd, 3rd, and 4th IV dose of rituximab 375 mg/m^2 on Days 1, 8, 15, and 22. Cmax was calculated in micrograms per millilitre (mcg/mL).

The recurrence or new onset of potentially organ- or life-threatening disease (i.e. one or more major Birmingham Vasculitis Activity Score for Wegener's Granulomatosis [BVAS/WG] items or disease severe enough to require treatment with cyclophosphamide)

  • For participants of reproductive potential (males and females), use of reliable means of contraception throughout the study participation
  • For all eligible participants mandatory prophylactic treatment for Pneumocystis jirovecii infection

Exclusion Criteria:

  • Diagnosis of Churg-Strauss syndrome, as defined by the Chapel Hill Consensus Conference
