About this study
Official title: Clinical Study of Stem Cells in the Treatment of Thin Endometrium
This is a non-blind self-control trial. We mainly compare the changes of endometrial thickness,changes in menstrual flow, and improvement in pregnancy before and after stem cell treatment in patients with thin endometrium.
Read the detailed description
According to the medical history and the results of the examination, the selected cases were screened and the informed consent was signed. After hysteroscopy, the collagen/umbilical cord mesenchymal stem cell was spread on a foley catheter, and placed in the uterine cavity, and 5 ml of saline was filled into the balloon. B-ultrasound confirmed that the stent was attached to the uterine wall. The balloon was removed in situ after 1 week. We mainly compare the endometrial thickness before and 6 months after surgery.

What participants receive. In a randomised study each person is assigned to one group by chance.
umbilical cord mesenchymal stem cells combined with collagen scaffoldDrug
3-7 days after the end of menstruation, we underwent hysteroscopic exploration and separation if there was intrauterine adhesions. Intraoperative endometrial biopsy, recording biopsy location, endometrial specimens sent to HE examination and immunohistochemistry (vwf detection of microvessel density). The umbilical cord mesenchymal stem cell combined with collagen scaffold was spread on the balloon scaffold and placed in the uterine cavity. 5 ml of saline was filled into the balloon, and B-ultrasound confirmed that the scaffold was attached to the uterine wall. The patient was hospitalized for 2 hours and the patient's vital signs were recorded.

What is being measured
The primary outcome is the main question the study is designed to answer.
the change of endometrial thickness
B-ultrasound measures and compares the endometrial thickness of the luteal phase before and after administration.
Measured: Change from Baseline endometrial thickness at 6 months
Secondary outcomes (3)
pregnancy rate
pregnancy rate = (pregnancy / observations) × 100%
Measured: pregnancy rate at 1 year
live birth rate
live birth rate = (live births / observations) × 100%
Measured: live birth rate at 1 year
abortion rate
abortion rate = (number of abortions / observations) × 100%
Measured: abortion rate at 1 year

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the change of endometrial thickness (time frame: Change from Baseline endometrial thickness at 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03724617, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
