About this study

Thin endometrium will lead to hypomenorrhea,infertility and recurrent pregnancy loss and there are few effective methods to increase the endometrial thickness and improve the fertility outcomes. Patients with thin endometrium will be divided into three groups and receive estrogen therapy, stem cell therapy and growth factor therapy respectively. This randomized controlled clinical study is carried out to explore the optimal treatment method and best indications for thin endometrium.

Being tested
CBD-bFGF, Collagen/BMMNCs, Estrogen

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CBD-bFGFDrug

    CBD-bFGF will be injected into the endometrium after hysteroscopy under the guidance of ultrasound

  • Collagen/BMMNCsDrug

    A collagen scaffold loaded with BMMNCs will be transplanted into the uterine cavity after hysteroscopy under the guidance of ultrasound

  • EstrogenDrug

    Patients will receive regular estrogen therapy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Endometrial thickness

    Endometrial thickness evaluated by transvaginal sonography during late proliferative phase

    Measured: 6 months

  2. Ongoing pregnancy rate

    The presence of a living intrauterine fetus on TVU at the 12th week of gestation

    Measured: 24 months

Secondary outcomes (4)
  1. Endometrial blood flow

    Endometrial blood flow evaluated by transvaginal sonography

    Measured: 6 months

  2. Pregnancy related complications

    Miscarriage rate, live birth rate, ET cycle cancellation rate,Placenta related complications

    Measured: 24 months

  3. Histological changes of endometrium

    Histological changes of the thin endometrium before and after treatment

    Measured: 12 months

  4. Menstrual blood volume

    The change of menstrual blood volume after treatment compared with pre-treatment

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CBD-bFGF, Collagen/BMMNCs and Estrogen in people with Infertility, Female, of Uterine Origin and Endometrial Fibrosis, run by Yali Hu at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 28 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yali Hu, MD,PhD (025-83106666 ext. 11201, glyyhuyali@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Endometrial thickness (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Sep 2022; AzTrials last refreshed its copy on 8 Nov 2026.
