System Organ Class: 10019805 - Hepatobiliary disorders
|

Intervention(s)
|
Trade Name: MabThera® Product Name: MabThera® Pharmaceutical Form: Concentrate for solution for infusion INN or Proposed INN: Rituximab CAS Number: 174722-31-7 Other descriptive name: N/A Concentration unit: mg milligram(s) Concentration type: equal Concentration number: 500- Pharmaceutical form of the placebo: Solution for infusion Route of administration of the placebo: Intravenous use
|
Primary Outcome(s)
|
Primary end point(s): Change in PBC-40 fatigue domain score between baseline and 12 week assessment in patients with severe fatigue (PBC-40 fatigue domain score >33 at study outset: a value validated against a control population in a now validated normal population version of the PBC-40. Change in the other domains of the PBC-40 will be assessed on the same basis as secondary outcome measures.
|
Secondary Objective: 1. To undertake a proof of efficacy clinical intervention study of B-cell depleting therapy in PBC patients with anti-PDH antibody (>95% of patients) who experience significant fatigue. The primary endpoint is reduction of fatigue severity assessed using a disease specific quality of life measure. 2. To explore the extent to which any such improvement in fatigue is related to reduction in the level of anti-PDH antibody in PBC patients and any associated effect on biomarkers of bioenergetic function assessed using unique MRS protocols developed by the CI and co-investigators. 3. To further explore the safety of Rituximab in PBC.
|
Timepoint(s) of evaluation of this end point: The primary endpoint is severity of fatigue as assessed using PBC-40, a disease-specific quality of life measure and will be evaluated at baseline, 12 weeks, and three monthly thereafter up to 12 months.
|
Main Objective: 1. Does Rituximab therapy significantly improve the fatigue experienced by patients with PBC? 2. Does any improvement in fatigue result from a reduction in the PDH-directed antibody response in PBC and the effects that these antibodies have on muscle cell energy generation? 3. What is the safety profile of Rituximab therapy in patients with PBC? 4. How sustained is any effect of Rituximab on fatigue?
|
Secondary Outcome(s)
|
Timepoint(s) of evaluation of this end point: Evaluation of the secondary endpoints will be at baseline and 12 weeks.
|
Secondary end point(s): The breadth of the clinical effect of Rituximab in PBC, exploring impact on other symptoms, functional status and mood, as well as the nature and severity of underlying liver injury.
The mechanism of action of Rituximab in terms of its effects on anti-PDH antibody of all isotypes and the B-cells producing it and the associated impact on muscle bioenergetic and cardiorespiratory function.
The acceptability of Rituxmab therapy for patients in terms of tolerability and safety.
