Belimumab & Rituximab Combination Therapy for the Treatment of Diffuse

Status Recruiting

Clinical Trial Summary

This is a 52 week, single center, randomized, double-blind, placebo-controlled study. After patients maintain a stable dose of Mycophenolate Mofetil (MMF) for at least 1 month, they will be randomized to treatment with either Belimumab & Rituximab or placebo.Patients in both groups will be on background MMF for the entirety of the study. Belimumab will be administered subcutaneously and Rituximab intravenously. Placebo injections and infusions will be of normal saline. Randomization will be done in a 2:1 manner to favor the treatment group. It is hypothesized that that Rituximab and Belimumab combination therapy with Mycophenolate Mofetil background therapy will improve fibrosis in SSc skin when compared to treatment with placebo and Mycophenolate Mofetil in a group of patients with early dcSSc.

Clinical Trial Description

The specific objectives of this study are to: 1. Determine whether rituximab/belimumab/mmf is safe and tolerable in the treatment of patients with early diffuse cutaneous (dc)SSc when compared to patients treated with placebo/placebo/mmf, as assessed by comparison of adverse and serious adverse effects. In this study stand of care will be protocolized as mycophenolate mofetil. 2. Determine whether rituximab/belimumab/mmf is more effective than placebo/placebo/mmf, as measured by change in CRISS, which is a composite outcome measure provisionally endorsed by the ACR for scleroderma clinical trials. It incorporates change in the mRSS, FVC percent predicted, physician and patient global assessments, and HAQ-DI. Additionally, hemoglobin corrected diffusion capacity (DLCO), Medsger Severity Scale (MSS), and by other physician and patient derived outcome measures will be used. 3. Determine the biological activity of rituximab/belimumab/mmf vs placebo/placebo/mmf as assessed by effect on histology of skin, gene expression of skin and blood, change in B-Cell profiles including assessment of B regulatory cells, and effect on serological and cutaneous biomarkers of disease activity. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
