Haukeland University Hospital
ClinicalTrials.gov Identifier:
NCT00848692
First received: February 19, 2009
Last updated: June 1, 2011
Last verified: June 2011
  Purpose

Based on pilot patient observations,the investigators anticipate that chronic fatigue syndrome (CFS) patients may benefit from B-cell depletion therapy.

The hypothesis is that at least a subset of CFS patients have an activated immune system involving B-lymphocytes, and that B-cell depletion may alleviate symptoms.
