Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eligible subjects who consent to participate will receive one dose of intravenous rituximab 375mg/m2 at study entry. Response to the initial study treatment will be assessed within 2 - 8 weeks. Response assessment is disease specific, but those achieving at least a partial response will then be observed. Participants achieving minimal or no response would then receive a second intravenous dose. Patients who fail to acheive at least a partial response to two doses would come off study. Those with a partial response or better, are observed. If relapsing after at least a 3 month response, up to two further doses may be administered at two week intervals. Total duration of intervention will depend on individual response but could be from 3 to 4 years. If further doses are indicated, they will also be at 375mg/m2 I.V.

Outcomes
Primary outcome [1] 2163 0
To describe the efficacy of abbreviated course rituximab in the treatment of auto-immune disease refractory to conventional immunosuppressive therapy using the parameters of response rate.
Timepoint [1] 2163 0
Disease specific autoantibodies are measured 4 weekly to week 12, 6 weekly to week 24, 12 weekly to week 96, then 6 monthly to 3 years. The schedule of testing will be altered if a second dose is administered with testing timepoints to date from the administration of the second dose.
Primary outcome [2] 2164 0
To describe the efficacy of abbreviated course rituximab in the treatment of auto-immune disease refractory to conventional immunosuppressive therapy using the parameters of durability of response. Disease specific autoantibodies are measured 4 weekly to week 12, 6 weekly to week 24, 12 weekly to week 96, then 6 monthly to 3 years. The schedule of testing will be altered if a second dose is administered with testing timepoints to date from the administration of the second dose.
Timepoint [2] 2164 0
Disease specific autoantibodies are measured 4 weekly to week 12, 6 weekly to week 24, 12 weekly to week 96, then 6 monthly to 3 years. The schedule of testing will be altered if a second dose is administered with testing timepoints to date from the administration of the second dose.
Secondary outcome [1] 3778 0
To evaluate the effect of abbreviated rituximab doses on parameters of B cell number and function.
Timepoint [1] 3778 0
B cell parameters will be assessed 2 weekly to week 4, 4 weekly to week 12, 6 weekly to week 24, 12 weekly to week 96 and 6 monthly to 3 years. The schedule of testing will be altered if a second dose is administered with testing timepoints to date from the administration of the second dose.
