Remestemcel-L for acute graft-versus-host disease therapy

Abstract

Introduction: Remestemcel-L (Prochymal®, Osiris) is an off-the-shelf adult mesenchymal stromal cell product that has been applied to acute graft-versus-host disease (aGvHD) for its immunomodulatory properties.

Areas covered: This article discusses preclinical and clinical studies supporting the use of remestemcel-L in aGvHD as well as the current regulatory status. This information was based upon a PubMed and Internet search.

Expert opinion: Phase II studies suggest remestemcel-L may have clinical activity in aGvHD and confirm tolerability. However, these results must be interpreted cautiously with any use of remestemcel-L optimally occurring in the context of a clinical trial. Further clarity will be obtained when the results of a completed Phase III study are published. There is a small market for remestemcel-L in aGvHD. A possible future scenario is that a more prevalent indication is found and remestemcel-L is approved for that indication, but use continues for aGvHD.
