Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Rituximab

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.

Group Type EXPERIMENTAL

Rituximab

Intervention Type 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.
