Prochymal™ Adult Human Mesenchymal Stem Cells for Treatment of Moderate-to-severe Crohn's Disease

Completed · Phase 2

Conditions studied: Crohn's Disease

In brief

Human mesenchymal stem cells (MSCs), derived from healthy adult volunteer human donors, can be obtained from bone marrow donation and cultured in the laboratory. MSCs have shown the ability to find injured tissue, reduce and control inflammation, and assist in tissue repair. Prochymal™ MSCs will be infused into patients with moderate-to-severe Crohn's disease. Infusions will occur on two separate days, 7-10 days apart. Patients will be monitored for reduced Crohn's disease symptoms.

• At some time during the course of the subject's Crohn's disease (CD), subject must have received both steroids and immunosuppressive agents (for example, azothioprine, 6-mercaptopurine, or methotrexate) which did not control the CD.
• Subject may be receiving antibiotics, 5-aminosalicylic acid, azathioprine, 6-mercaptopurine, methotrexate, prednisone, or any similar drugs at the time of enrollment.

• The dose of steroids must have been stable for at least 4 weeks prior to enrollment.
• The dose of antibiotics must have been stable for at least 4 weeks prior to enrollment.
• The dose of immunosuppressants (for example, azathioprine, 6-mercaptopurine [6-MP], or methotrexate) must have been stable for at least 8 weeks prior to enrollment and the subject on therapy for at least three months prior to enrollment.
• Subject must have adequate renal function as defined by a calculated creatinine clearance of greater than 30 ml/min using the Cockcroft-Gault equation, and a serum creatinine concentration of less than 2.0 mg/dl.
• Subject must be available for all specified assessments at the study site through day 30.
• Subject must provide a written informed consent form (ICF) and authorization for use of and disclosure of personal health information (PHI).

You may not qualify if…

• Subject has any alcohol or substance abuse within 6 months of randomization.
• Subject has evidence of fibrostenotic obstructive Crohn's disease.
• Subject has an active infection with HIV or hepatitis B or C.

• Subject has received infliximab; adalimumab; or other antibody, protein, or biological therapy not specifically approved by the United States Food and Drug Administration (FDA) for Crohn's disease for 90 days (d) prior to enrollment in study.
• Subject has received prednisone greater than 20 mg/d at any time 28 d prior to enrollment in study.

• Subject has cardiopulmonary disease that, in the opinion of the Investigator, is either unstable or severe enough to justify exclusion from this study.
• Subject has any underlying or current medical or psychiatric condition that, in the opinion of the Investigator, would make participation in the study unsafe.
