Inclusion criteria
Inclusion criteria: - Provision of informed consent - Males and females 18 - 80 years of age. - Active rheumatoid arthritis (RA) diagnosed according to the 2010 ACR/EULAR classification criteria. Patients must be positive for rheumatoid factor (RF) and/or anti-cyclic citrullinated peptide (anti-CCP3) antibodies and must have early (6 months – 2 years disease duration) RA but without the poor prognostic features of functional limitation or extra-articular disease. - Patients must have: > 4 tender joints (TJC) count (28 joint count) at screening and > 4 swollen joint (SJC) count (28 joint count) at screening Erythrocyte sedimentation rate (ESR) > 28 mm/hr OR hsCRP greater than ULN. - Patient has been taking at least one and up to 3 synthetic oral DMARDS as combination therapy for at least 6 months, of which the 8 weeks preceding enrollment were at stable dose and route of administration between 15 and 25 mg/week for MTX, and the patient has not had adequate response as determined by the investigator and findings as specified above. - Women of child bearing potential must use effective contraception. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 60 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 30
Exclusion criteria
Exclusion criteria: - Use of more than 3 synthetic oral DMARDs. - Prior use of anti-TNF or other biologic for treatment of rheumatoid arthritis at any point prior to screening. - Other investigational therapy received within 8 weeks or five half-lives (whichever is longer) prior to Screening or any prior regenerative therapy treatments (including participation in any stem cell or regenerative medicine study) - Pregnant or breast-feeding. - Autoimmune disease other than RA - History of or current inflammatory joint disease other than RA. - Bedridden or confined to a wheelchair or patients who have had > 3 arthroplasties due to RA. - Known hypersensitivity to dimethyl sulfoxide (DMSO), murine or bovine protein. - Prior treatment with any cell-depleting therapies including investigational agents. - Gold compounds if less than 8 weeks prior to randomization; immunoadsorption columns if less than 6 months prior to baseline. - QTc = 450 ms for males and QTc = 470 ms for females at Screening.

| Main Objective: 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 not previously received treatment with biologics.;Secondary Objective: 1. To demonstrate the efficacy of a single intravenous infusion of allogeneic mesenchymal precursor cells (MPCs) compared to placebo at 12 weeks post-infusion with MPCs or placebo in the treatment of patients with active rheumatoid arthritis (RA) who have not previously received treatment with biologics. 2. To evaluate the long-term efficacy and safety of allogeneic mesenchymal precursor cells (MPCs) over the entire study duration in the treatment of patients with active rheumatoid arthritis (RA) who have not previously received treatment with biologics. Exploratory Objective: To determine change from baseline of serum biomarkers: IL-1, -6, -17; TNFa, TGFß; osteocalcin, RANKL; MMP-1, -3, -9, TIMP-1, -2, -4 IFN-gamma, CD-206 monocytes (via flow cytometry) and FOXP3+ lymphocytes (via flow cytometry).;Primary end point(s): Primary objective Safety will be assessed by: -Adverse events/serious adverse events (“primary endpoint”) - Vital signs (BP, HR, RR, SpO2, temperature) - Physical examination - Clinical laboratory tests (hematology, biochemistry, and urinalysis, flow cytometry Class I and Class II PRA % with specificity, antibovine and antimurine antibody analysis) - Electrocardiogram (ECG) - Pulmonary function tests (lung volumes, DLCO, spirometry (FEV1, FVC)) - Chest x-ray (CXR);Timepoint(s) of evaluation of this end point: 12 weeks post study product infusion | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary objectives 1. Efficacy will be assessed by: - ACR20 - ACR50 - ACR70 - DAS28 (mean changes from baseline as measured using hsCRP) - 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)1 - Joint erosion of hands and wrists assessed via x-ray - Patient reported outcomes - Short-Form Health Survey Version 2.0. (SF36v2) - Health Assessment Questionnaire Disability Index (HAQ-DI) as part of the ACR core set of measures for response criteria 2. Safety will be assessed by: -Adverse events/serious adverse events (“primary endpoint”) - Vital signs (BP, HR, RR, SpO2, temperature) - Physical examination - Clinical laboratory tests (hematology, biochemistry, and urinalysis, flow cytometry Class I and Class II PRA % with specificity, antibovine and antimurine antibody analysis) - Electrocardiogram (ECG) - Pulmonary function tests (lung volumes, DLCO, spirometry (FEV1, FVC)) - Chest x-ray (CXR) Exploratory objective - smeasurement of serum biomarkers: IL-1, -6, -17; TNFa, TGFß; osteocalcin, RANKL; MMP-1, -3, -9, TIMP-1, -2, -4.;Timepoint(s) of evaluation of this end point: 1. Efficacy at 12 weeks post study product infusion 2. Efficacy and safety over entire duration of study Exploratory: Various timepoints during study | — |
