Treatment of Chronic Obstructive Pulmonary Disease by Infusion of Allogenic Mesenchymal Stem Cells

Patients with chronic obstructive pulmonary disease (COPD) are characterized with airflow limitation and chronic inflammation, which is caused by cigarette smoking, noxious particles or gases. These inhaled irritants will induce inflammation, emphysema and fibrosis though chronic exposure. The current pharmacological treatment of COPD is symptomatic and is mainly based on bronchodilators and corticosteroids. Although current clinical treatment strategies can improve and stabilize COPD states and quality of life, none of them are able to modify the progressive decline in lung function, meaning it gradually gets worse over time. Therefore, development of new therapeutic modalities to improve the clinical outcomes and prognosis of COPD in adult patients is of urgent need. Among the more innovative, experimental therapies, mesenchymal stromal cells are proposed as a novel therapy with potential in treatment of COPD. This clinical trial is a phase II study. It is a randomized, placebo-controlled, double-blind study. Eligible subjects will be randomized to one of the three groups: placebo control, low-dose UMC119-06-05 treatment, or high-dose UMC119-06-05 treatment. Subjects will receive a single-dose IV infusion to evaluate the efficacy and long-term safety of UMC119-06-05 with moderate to severe COPD.
