Evaluation of PROCHYMAL® Adult Human Stem Cells for Treatment-resistant Moderate-to-severe Crohn's Disease

Phase 3
Completed
Conditions
Crohn's Disease
Interventions
Drug: Prochymal®
Drug: Placebo
Registration Number
NCT00482092
Lead Sponsor
Mesoblast, Inc.
Brief Summary

Protocol 603 is enrolling subjects with moderate-to-severe Crohn's disease who are intolerant to, or have previously failed therapy with, at least one steroid and at least one immunosuppressant and a biologic monoclonal anti-body to tumor necrosis factor alpha. The protocol investigates the safety and efficacy of using PROCHYMAL® adult human stem cells to induce remission. PROCHYMAL is delivered through a vein in the arm four times over two weeks, for approximately an hour each time.

Detailed Description

A significant number of individuals with Crohn's disease do not find relief with existing steroidal, immunosuppressive, or biologic therapies, and are forced to seek surgery or other drastic measures for treatment.

PROCHYMAL® adult human stem cells are manufactured from healthy, volunteer donors, extensively tested, and are stored to be available as needed. Human and animal studies have shown that the cells do not require any donor-recipient matching. The cells may have both immunosuppressive and healing benefits in Crohn's disease. The cells naturally migrate specifically to sites of inflammation, so their effects are believed to be local and self-limiting rather than systemic.

Protocol 603 is enrolling subjects to evaluate the ability of PROCHYMAL to induce remission in subjects with moderate-to-severe disease (Crohn's disease activity index -- CDAI -- of between 250 and 450, inclusive) who have failed or been intolerant of at least one drug in each of the steroid, immunosuppressant, and biologic classes.
