Intravenous Infusion of Umbilical Cord Blood-Derived Mesenchymal Stem Cells in Rheumatoid Arthritis: A Phase Ia Clinical Trial.
Based on immunomodulatory actions of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs), in vitro or preclinical studies of hUCB-MSCs have been conducted extensively in rheumatoid arthritis (RA). However, few human trials have investigated the outcomes of hUCB-MSC infusions. The CURE-iv trial was a phase I, uncontrolled, open label trial for RA patients with moderate disease activity despite treatment with methotrexate. ⋯ Reduced levels of IL-1β, IL-6, IL-8, and TNF-α at 24 hours were observed in the cluster infused with 1 × 108 MSCs. This phase Ia hUCB-MSC infusion trial for established RA patients revealed no short-term safety concerns. Stem Cells Translational Medicine 2018.
