NCT04440670

Brief Summary

This is the first and largest randomized, controlled, blinded trial that evaluates the efficacy of autologous cord blood mononuclear cells infusion as a prevention therapy for BPD or death. The results of this trial will provide valuable clinical evidence for recommendations on the management of BPD in extremely preterm infants. In this prospective, randomized controlled double-blind multi-center clinical trial, 140 extremely preterm neonates less than 28 weeks are randomly assigned to receive intravenous autologous cord blood mononuclear cells infusion (targeted dose of 5×107cells/kg but no less than 1×107cells/kg) or placebo ( normal saline) within 24 hours after birth in a 1:1 ratio using a central randomization system. The primary outcome is survival without bronchopulmonary dysplasia at 36 weeks of postmenstrual age or discharge home. The secondary outcomes will include mortality rate, BPD severity, other common preterm complication rate, respiratory support duration, the length and cost of hospitalization and long term outcomes after two years follow up post infusion.

Outcome Measures

Primary Outcomes (1)

  • frequency of bronchopulmonary dysplasia or death

    The frequency of bronchopulmonary dysplasia or death at 36 weeks of postmenstrual age or discharge home whichever comes first.

    36 weeks of postmenstrual age or discharge home whichever comes first.

Secondary Outcomes (1)

  • mortality

    36 weeks of postmenstrual age or the discharge

Study Arms (2)

ACBMNC infusion group

EXPERIMENTAL

Those assigned to the ACBMNC group will receive intravenous autologous cord blood mononuclear cells infusion within 24 h after birth. Cell dose for all patients was targeted at 5×107 cells per kilogram.

Biological: autologous cord blood mononuclear cells

control group

PLACEBO COMPARATOR

Those in control group will receive an infusion of a placebo solution which is normal saline with the same volume.

Biological: normal saline

Masking Details
A hospital ethics committee reviewed the study data during the trials. None of them were involved in the study or aware of the treatment-group assignments of the infants. Only nurses and physicians staff conducted the infusion were aware of the treatment assignment, and these individuals had no contact with the staff who collected and analyzed the patients data. The parents are not aware of the assignment. This study is double-blinded.
