Human Umbilical-Cord-Derived Mesenchymal Stem Cell Therapy in Acute Lung Injury

Phase 1

• Conditions: Acute Lung Injury; Acute Respiratory Distress Syndrome
• Interventions: Biological: UCMSC group

• Registration Number: NCT02444455
• Lead Sponsor: Affiliated Hospital to Academy of Military Medical Sciences

Brief Summary

Phase I-II Clinical Trial - Safety and efficacy of umbilical-cord-derived mesenchymal stem cell (UC-MSC) in patients with Acute Lung Injury ,open label, controlled prospective study.

Detailed Description

Phase I-II Clinical Trial - Safety and efficacy of umbilical-cord-derived mesenchymal stem cell (UC-MSC) in patients with acute lung injury,open label, controlled prospective study.

Every patient will maintain their standard treatment of acute lung injury, with maximum tolerated dosage without side effects.

The day of infusion will be considered day zero. From that moment, followup will be divided into 2,7,14 days.

Clinical results will be analyzed after completion of 14 days of followup.

Arm && Interventions

Group	Intervention	Description
UCMSC group	UCMSC group	Human umbilical cord MSCs are administrated to patients by intravenous infusion

Primary Outcome Measures

Name	Time	Method
Safety will be determined by the assessment of major adverse events	From day 0 at the start of treatment to day 14.	Safety will be determined by the assessment of major adverse events defined as death, and the incidence of prespecified infusion-associated events and non-serious adverse events thought to be related to the MSC infusion.

Secondary Outcome Measures

Name	Time	Method
The efficacy of UC-MSC treatment was measured by biological markers,including markers of inflammation，IL-8	6 hours post-infusion, and days 1, 2, and 3
The efficacy of UC-MSC treatment was measured by arterial blood gas analysis	Participants will be followed for the duration of hospital,2 day post-infusion, and days 7,14.
The efficacy of UC-MSC treatment was measured by biological markers,including markers of inflammation，IL-6	6 hours post-infusion, and days 1, 2, and 3
Quantify pulmonary respiratory function measured by chest computerized tomography	Participants will be followed for the duration of hospital,2 day post-infusion, and days 7,14.
