What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 90 participants in total. It began in 2024-06-11 with a primary completion date of 2026-12-30.

Brief Summary

This phase II study is a randomized, placebo-controlled, double-blind study to evaluate the safety and efficacy of UMC119-06-05 compared to placebo in treating subjects with moderate to severe COPD. Eligible subjects will receive a single-dose IV infusion of UMC119-06-05 or placebo.

Has initiated pulmonary rehabilitation (e.g., exercise training) within 3 months prior to screening which, in the opinion of the Principal Investigator (PI), may affect the study's results. 4. Has documented history of uncontrolled heart failure. 5. Has pulmonary hypertension due to left heart condition. 6. Has atrial fibrillation or significant congenital heart defect/disease. 7. Has had a moderate or severe exacerbation of COPD (defined by GOLD standard) or has required mechanical ventilation (not including continuous positive airway pressure \[CPAP\]) within 30 days prior to screening. 8.
