Mesenchymal Stem Cells for The Treatment of Acute Respiratory Distress Syndrome (ARDS)

The Safety and Tolerability After Intravenous Infusion of UMC119-06 in Subjects With Acute Respiratory Distress Syndrome (ARDS).

The clinical study with UMC119-06 is designed to investigate the safety in patients with moderate acute respiratory distress syndrome ("ARDS"). This will be a dose escalation, open-label, single-center study in adult with ARDS. UMC119-06 is ex vivo cultured human umbilical cord derived mensenchymal stem cells (hUC-MSCs) product which is intended for treatment of ARDS.

Study Overview

• Status: Not yet recruiting
• Conditions: Acute Respiratory Distress Syndrome
• Intervention / Treatment: Biological: UMC119-06

Detailed Description

ARDS, a noncardiogenic respiratory disease, is characterized by progressive hypoxemia and respiratory distress, associated with explosive acute inflammation and alveolar edema. ARDS occurs in all age group of patients, where mortality rates increase in advancing age.

In animal studies of ARDS, mensenchymal stem cells (MSCs) can attenuate lipopolysaccharides (LPS)-induced lung injury and pulmonary permeability edema through modulating the inflammatory. These findings show that MSCs may improve the clinical outcomes and prognosis of ARDS patient. Meridigen is developing UMC119-06, human umbilical cord-derived MSCs, for the treatment of ARDS. The purpose of this study is to assess the safety of UMC119-06 in patients with ARDS.

  2. Bilateral infiltrates consistent with pulmonary edema on frontal chest radiograph.
  3. Hypoxemia: PaO2/ FiO2 > 100 mmHg to ≤ 200 mmHg with PEEP ≥ 5 cm H2O.
  4. The time of onset of ARDS is when all of the specified ARDS criteria (2a-c) are met.
• Patient is intubated and mechanically ventilated.

• Subjects with body weight between 40 to 90 kg.
• No decompensated heart failure.
• Subject is willing to provide written informed consent to participate in the study after reading the informed consent form and the information provided.

• Women of child-bearing potential should have a negative serum pregnancy test prior to administration of investigational product., UNLESS they meet the following criteria:
