B-cell Depletion Using the Monoclonal Anti-CD20 Antibody Rituximab in Chronic Fatigue Syndrome

NCT01156909 | Completed Phase 2

• 1 other identifier: 2010/1318
• Study Type: interventional
• Target: 29
• Locations: 1 country
• Sites: 1

Brief Summary

Based on pilot patient observations, and experience from the prior study KTS-1-2008, the investigators anticipate that chronic fatigue syndrome patients may benefit from B-cell depletion therapy using Rituximab induction with maintenance treatment. The hypothesis is that at least a subset of CFS patients have an activated immune system involving B-lymphocytes, and that prolonged B-cell depletion may alleviate symptoms.

Conditions

Chronic Fatigue Syndrome; Myalgic Encephalomyelitis

Keywords

Chronic fatigue syndrome; CFS; Myalgic encephalomyelitis; Rituximab; B-cell depletion

Outcome Measures

Primary Outcomes (1)

• Symptom alleviation, as compared to baseline, measured by standardized self-reports and quality of life schemes.

  The primary endpoint is defined as major response of the CFS symptoms, of at least six weeks duration, independent on when during 36 months follow-up the response period(s) occurs. Single such response periods, and the sum of these, are recorded.

  Major response of at least six weeks duration, independent on when occuring, during the follow-up period.

Secondary Outcomes (1)

• Symptom alleviation, as compared to baseline, measured by standardized self-reports and quality of life schemes.

  At 3, 6, 10, 15, 20, 24, 30, 36 months after intervention

Study Arms (1)

Rituximab

EXPERIMENTAL

Rituximab induction using two infusions (500mg/m2, max 1000 mg) two weeks apart, followed by maintenance Rituximab infusions (500 mg/m2, max 1000 mg) after 3, 6, 10 and 15 months.

Drug: Rituximab

Interventions

Rituximab DRUG

Two infusions of Rituximab 500 mg/m2 (max 1000 mg) given two weeks apart, followed by maintenance Rituximab infusions 500 mg/m2 (max 1000 mg) at 3, 6, 10, and 15 months. Approved amendment: for patients with gradual improvement in CFS/ME symptoms after 12 months follow-up, but not having reached a clear response, up to 6 additional Rituximab infusions (500 mg/m2, max 1000 mg) may be given during the following 12 months period.
