A Multi-center Study a Single IV Infusion of Allogeneic MPCs in Patients With Rheumatoid Arthritis and Incomplete Response to at Least One TNFα Inhibitor

25. juni 2020 oppdatert av: Mesoblast, Ltd.

A Double-blind, Randomized, Placebo-controlled, Dose-escalation, Multi-center Study a Single Intravenous Infusion of Allogeneic Mesenchymal Precursor Cells (MPCs) in Patients With Rheumatoid Arthritis and Incomplete Response to at Least One TNFα Inhibitor

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.

Inclusion Criteria:

  • Males and Females ages 18-80 years old
  • Active rheumatoid arthritis (RA) disease as per 2010 ACR/EULAR classification criteria for the diagnosis of RA.
  • Must be positive for rheumatoid factor and/or anti-cyclic citrullinated peptide (anti-CCP3) but without extra-articular disease or functional limitation

  • Patient with active RA defined as:

    • ≥ 4 tender joint count (TJC) 28 joint count at screening and
    • ≥ 4 swollen joint count (SJC) count 28 joint count at screening
    • ESR ≥ 28 mm/hr or hsCRP >2.0 mg/L
  • Patient has been taking MTX for at least 4 months with dose and route of administration stable for at least 8 weeks prior to screening
  • Patient has had an inadequate response to at least one TNFα inhibitor with last dose at least 6 weeks prior to screening

Tidsramme: 12 weeks post IV Infusion

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

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

  • Clinical laboratory tests
  • Electrocardiogram
  • Chest x-ray (CXR)

Efficacy will be assessed according to the following:

  • 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
