Malignancy within the previous five years, except adequately treated basal cell carcinoma, provided that it is neither infiltrating nor sclerosing, and carcinoma in situ of the cervix 19.

Clinically relevant abnormal findings in the clinical history, physical examination, ECG, or laboratory tests at the screening assessment that would interfere with the objectives of the study or would preclude safe completion of the study. Abnormal findings could include: known HIV infection or other immunodeficiency state, chronic active viral infection (such as hepatitis B or C), acute systemic infections (defined as patients undergoing treatment with antibiotics), gastrointestinal tract bleeding, or any severe or acute concomitant illness or injury 26. Any other medical, social, or geographical factor that would make it unlikely that the patient could comply with study procedures (e.g., alcohol abuse, lack of permanent residence, severe depression, disorientation, distant location, or noncompliance)

| Study Population itMSC, then Placebo: Participants first received itMSC 1.5 million per kilogram of weight, infused in the corresponding hospital facility at speed of 1 mL/minute (cell concentration 1 million/mL). After 90 days patients completed treatment at 90 days, and thus constituted the control treatment. After 90 day follow-up testing patients received Placebo and followed up for another 90 days. Total efficacy follow-up - 180 days. Safety follow-up - 240 days.
