Phase 1
Conditions
Paraquat Poisoning
Lung Injury
Interventions
Other: Control group(Normal saline)
Biological: UCMSC group
Registration Number
NCT02444858
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 paraquat poisoning induced lung injury, randomized,single blind, 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 paraquat poisoning induced lung injury,randomized, single blind, controlled prospective study.

Forty patients will be selected and randomized into two groups: the first group of 20 patients will receive three-time injection of UC-MSC and the remaining 20 patients will comprise the control group.

Every patient will maintain their standard treatment of paraquat poisoning, with maximum tolerated dosage without side effects.

The day of last infusion will be considered day zero. From that moment, followup will be divided into 2 d,7 d,14 d, 28 d and 2 m.

Clinical results will be analyzed after completion of 2 months of followup.

Primary Outcome Measures
NameTimeMethod
Safety will be determined by the assessment of major adverse events.2 months

Safety will be determined by the assessment of major adverse events defined as trial-related death,required hospitalization or prolonged hospitalization time, persistent or significant loss of organ function,other serious adverse events.

Secondary Outcome Measures
NameTimeMethod
The efficacy of UC-MSC treatment was measured by chest computerized tomography.2 months

The efficacy of UC-MSC treatment was quantified by the differences between the two groups and from baseline to 2 months, as measured by chest computerized tomography(CT).

The efficacy of UC-MSC treatment was measured clinical evaluation.2 months

The efficacy of UC-MSC treatment was measured clinical evaluation defined as wheezing, coughing and other symptoms improved than before.

The efficacy of UC-MSC treatment was measured by lab Indicators.2 months

The efficacy of UC-MSC treatment was measured by lab Indicators defined as blood cell analysis, markers of inflammation (C-reactive protein).

The efficacy of UC-MSC treatment was monitored by pulmonary function.2 months

The pulmonary function efficacy of UC-MSC treatment was measured by arterial blood gas analysis (oxygenation index).
