A Phase 3 interventional study of autologous cord blood mononuclear cells in BPD, sponsored by Guangdong Women and Children Hospital. Status unknown at 2 sites in China. Open to participants aged Up to 28 Weeks. Per ClinicalTrials.gov, last updated 2021-10-08.
Sponsored by Guangdong Women and Children Hospital · Phase 3, Interventional, and Treatment
This is a non-randomized, case-controlled trial that evaluates the efficacy of autologous cord blood mononuclear cells(ACBMNC) infusion as a Treatment for BPD. The results of this trial will provide valuable clinical evidence for recommendations on the treatment of BPD in extremely preterm infants. Informed consent before birth is signed. In this prospective clinical trial, preterm neonates less than 28 weeks who previously stored ACBMNC and then suffer BPD will be assigned to be ACBMNC infusion group, while those who do not previously stored ACBMNC or then refuse ACBMNC infusion and suffer BPD will be assigned to be control group. In the ACBMNC infusion group, when BPD occurred, the pre-stored ACBMNC will be removed and rewarmed, and then ACBMNC(5×107 cells /kg) will be intravenously injected within 24 hours. The control group receives standardized treatment without special treatment. The total number of participants is 76 and the same in both groups. The primary outcome is the rate of mortality or ratio of severe BPD at 36 weeks of postmenstrual age or discharge home. The secondary outcomes will include other common preterm complication rate and the number of hospitalizations due to pneumonia within 1 year of postmenstrual age.
Study design and settings:
This is a non-randomized, case-controlled trial that evaluates the efficacy of autologous cord blood mononuclear cells(ACBMNC) infusion as a Treatment for BPD. Informed consent before birth is signed. Preterm infants in the ACBMNC infusion group will have their umbilical cord blood collected after birth. Umbilical cord blood was collected into a collection bag after delivery and labeled. The collection bag was placed in a 4° refrigerator for refrigeration and sent to the Guangdong Province umbilical cord blood Bank. ACBMNC will be separated and preserved with liquid nitrogen. The total content of umbilical cord blood cells, the number of mononuclear cells per ml and the volume before and after separation were provided immediately for the later calculation of the total volume of infusion. In this prospective clinical trial, preterm neonates less than 28 weeks who previously stored ACBMNC and then suffer BPD will be assigned to be ACBMNC infusion group, while those who do not previously stored ACBMNC or then refuse ACBMNC infusion and suffer BPD will be assigned to be control group. In the ACBMNC infusion group, when BPD occurred, the pre-stored ACBMNC will be removed and rewarmed, and then ACBMNC(5×107 cells /kg) will be intravenously injected within 24 hours. The control group receives standardized treatment without special treatment. The total number of participants is 76 and the same in both groups. The primary outcome is the rate of mortality or ratio of severe BPD at 36 weeks of postmenstrual age or discharge home. The secondary outcomes will include other common preterm complication rate and the number of hospitalizations due to pneumonia within 1 year of postmenstrual age.
Trial treatment methods:
Informed consent before birth will be signed by the parents. All premature infants included in the study received standardized treatment after admission to the NICU. In the ACBMNC infusion group, when BPD occurred, the pre-stored ACBMNC will be removed and rewarmed, and then ACBMNC(5×107 cells /kg) will be intravenously injected within 24 hours. The control group receives standardized treatment without special treatment.

Biological: autologous cord blood mononuclear cells
The control group received standardized treatment without special treatment.
preterm neonates less than 28 weeks who suffer BPD and also stored cord blood are assigned to receive intravenous autologous cord blood mononuclear cells infusion (5×107cells/kg).
Rate of mortality or ratio of severe BPD
Rate of mortality or ratio of severe BPD at discharge or corrected gestational age at 36 weeks
Time frame: 36 weeks of postmenstrual age or discharge home whichever comes first.
Incidence of other preterm complications
