Interventions

  • Rituximab — DRUG
    Rituximab is a monoclonal antibody that targets cluster of differentiate 20 (CD20) present on B-cells and lowers humoral immunity. Rituximab has been used successfully as a desensitization agent to treat Highly Human Leukocyte Antigens (HLA)-sensitized patients planning renal transplant. All cases of antibody-mediated rejection were seen in the placebo group, none in the Rituximab group. Rituximab has been safely used with Methotrexate in the treatment of Rheumatoid Arthritis, where co-administration of Methotrexate and Rituximab results in better outcomes than either medication alone. We propose this safety and feasibility open-label trial that will examine if Rituximab pre-treatment before Standard-of-Care Methotrexate-Pegloticase will result in recapture of Pegloticase efficacy as measured by serum urate (SU) \< 6 mg/dL throughout the trial and up to 6-months of Methotrexate-Pegloticase administration.

Study Details

This safety and feasibility, open-label study of up to 9 subjects will examine a group of subjects with poorly controlled tophaceous gout (intolerant to or ineffective oral urate lowering agents and loss of prior Pegloticase response) pre-treated with Rituximab to recapture response to Methotrexate-Pegloticase.

Arms

  • Experimental: Rituximab
    Rituximab 1000 mg will be administered at week -6 and week -4 via intravenous infusion over the duration of 5 hours prior to the Pegloticase (Standard-of-Care) treatment.

Primary Outcome Measure

The study will be measured by the frequency and grade of adverse event (AEs) (solicited and unsolicited), serious adverse experience (SAEs), adverse event of special interest (AESI1s), medically attended adverse events (MAAEs). [ Time Frame: 2 years ]
