Brief Summary:
Study is a double-blind, randomized, placebo controlled, dose escalating study. The primary objective of this study is to evaluate the safety, tolerability and feasibility of a single intravenous infusion of allogeneic mesenchymal precursor cells (MPCs) compared to placebo at 12 weeks post-infusion in the treatment of patients with active rheumatoid arthritis (RA) who have received methotrexate +/- other DMARDs for at least 6 months prior to screening and who have had an incomplete response to at least one TNF-alpha inhibitor.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Evaluation of the safety of a single IV infusion of allogeneic MPCs compared to placebo at 12 weeks post-infusion [ Time Frame: 12 weeks post IV Infusion ]

    To evaluate the safety, tolerability and feasibility of a single intravenous (IV) infusion of allogeneic mesenchymal precursor cells (MPCs) compared to placebo at 12 weeks post-infusion in the treatment of patients with active rheumatoid arthritis (RA) who have received methotrexate +/- other oral DMARDs for at least 4 months and who have had an incomplete response to at least one course of a TNFα inhibitor.

    Overall safety will be based on the overall assessment of AE/SAEs, Vital Signs, Physical Examination, clinical laboratory tests, ECGs and Chest x-ray.



Secondary Outcome Measures :
  1. Evaluation of the efficacy of a single intravenous infusion of allogeneic MPCs compared with placebo at 12 weeks post-infusion with MPCs or placebo in the treatment of patients with active RA [ Time Frame: 12 weeks post IV infusion with MPCs ]
    To assess the efficacy of a single intravenous infusion of allogeneic MPCs compared with placebo at 12 weeks post-infusion with MPCs or placebo in the treatment of patients with active RA who have received methotrexate +/- other DMARDs for at least 4 months and who have had an incomplete response to least one TNFα inhibitor.

  2. Evaluation of long-term safety and efficacy of a singly IV infusion of allogeneic MPCs in patients with active RA [ Time Frame: 52 weeks post IV Infusion ]

    To evaluate the long-term efficacy and safety of allogeneic MPCs over the entire study duration in the treatment of patients with active RA who have received methotrexate +/- other DMARDs for at least 4 months and who have had an incomplete response to at least one TNFα inhibitor

    Safety will be assessed according to the following:

    • Adverse events/serious adverse events ("primary endpoint")
    • Vital signs
    • Physical examination
    • Clinical laboratory tests
    • Electrocardiogram
    • Chest x-ray (CXR)

    Efficacy will be assessed according to the following:

    • ACR20/50/70
    • DAS28 (mean changes from baseline as measured by using hsCRP and ESR)
    • Mean changes from baseline in all components of the ACR core response criteria
    • Remissions (as defined in the 2011 Joint Statement of the American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR)
    • Joint erosion of hands and wrists assessed via x-ray

    • Patient-reported outcomes

      • SF36v2
      • HAQ_DI
