    A recently published French clinical trial of Rituximab for Sjögren Syndrome patients.
    There was not a significant outcome in this trial when assessed at six months.

    Here's a couple of articles that explain the results:

    "The results of this study suggest that rituximab (Rituxin) treatment is not associated with a significant improvement in symptoms or disease activity at 6 months for patients with primary Sjogren syndrome (pSS)."

    "There were transient improvements in fatigue symptoms at 6 weeks, but the benefits were no longer significant at 6 months."

    I'm not sure you would expect an improvement at 6 months given treatment was weeks 0 and 2. Rituximab will wipe out b-cells and hence eventually antibodies but they come back without repeated treatment.

    Good point. I can't remember the time scale that B cells are expected to be replenished.
