About this study

Official title: Didroxyprogesterone Promotes Postoperative Natural Pregnancy in Infertile Patients With Mild and Moderate Endometriosis

Endometriosis (EM) is an important cause of infertility in women of childbearing age. Laparoscopic surgery is the treatment of EM Related infertility is an important method. However, excluding other infertility factors, the natural pregnancy rate of EM patients one year after operation is still significantly lower than that of normal couples. At the same time, the high recurrence rate of EM often requires drugs to inhibit ovulation after operation, which forms a paradox with the demand for fertility. One year after operation is the "golden period" of natural pregnancy. Whether to treat the recurrence of EM without affecting or even promoting fertility is a key problem to be solved in clinic. Didroxyprogesterone is the closest natural progesterone. It is widely used in luteal support and treatment of threatened abortion. It does not affect ovulation and is harmless to embryos. In recent years, clinical studies have found that it is helpful to the natural pregnancy of patients with EM after operation, and is beneficial to improve pain symptoms and reduce the recurrence rate. Basic studies have also confirmed the inhibitory effect of didroxyprogesterone on em. However, the existing studies with small sample size are not enough to draw a convincing conclusion that didroxyprogesterone promotes the pregnancy rate after em, and there is a lack of Chinese data. This study intends to use a multicenter, prospective, open, randomized controlled clinical trial design to explore the value of didroxyprogesterone in the treatment of EM related infertility patients, so as to provide direct evidence for improving the postoperative natural pregnancy rate of EM patients.

Read the detailed description

Female patients aged 22-35 who had been diagnosed with mild to moderate endometriosis by laparoscopic surgery and had undergone surgical treatment and fertility index (EFI) score ≥5 were stratified and randomized at each branch center. The study subjects were first stratified according to EFI score, which was divided into three levels: 5-6 points, 7-8 points and 9-10 points. Then the patients were divided into 2 groups in stratification according to the segmented random method. ① Dydrogesterone group: the first postoperative menstrual cycle began on the 14th to 27th day of each menstrual cycle, dydrogesterone 10mg bid oral administration, planned to use 6 menstrual cycles (if the patient conceived naturally during the medication, the drug could be stopped), and instructed the patient to try pregnancy, observation period was 12 postoperative menstrual cycles; ② Control group: postoperative medication was not used to guide patients to try pregnancy, and the observation period was 12 menstrual cycles after surgery. The subjects should be followed up for a maximum of 6 times, respectively within the first month after surgery, the first menstrual cycle D7-13 after surgery, the fourth menstrual cycle D7-13 after surgery, the seventh menstrual cycle D7-13 after surgery, the 13th menstrual cycle D7-13 after surgery, and 1-2 months after pregnancy termination.

Outcome measures: ① Pregnancy status; ②EM symptoms and recurrence related indicators: VAS score, physical examination, CA125, gynecological B-ultrasound examination results; ③ Drug safety assessment: AMH, blood routine examination, liver and kidney function, and the patient's combined drug use and possible drug-related adverse reactions were recorded.

  • didroxyprogesteroneDrug

    Also called duphaston

    Didroxyprogesterone group: the first menstrual cycle after operation began on the 14th to 27th day of each menstrual cycle. Didroxyprogesterone 10mg bid was given orally. It was planned to use 6 menstrual cycles (if the patient was naturally pregnant during the medication, the drug could be stopped), and guide the patient to try pregnancy. The observation period was 12 menstrual cycles after operation. Control group: no drugs were used after operation, and the patients were guided to try pregnancy. The observation period was 12 menstrual cycles after operation. Subjects need to complete up to 6 follow-up visits, including the first month after operation, the first menstrual cycle d7-13 after operation, the fourth menstrual cycle d7-13 after operation, the seventh menstrual cycle d7-13 after operation, the 13th menstrual cycle d7-13 after operation and 1-2 months after termination of pregnancy

A Phase 3 study testing didroxyprogesterone in people with Pregnancy Rate, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University.

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 4 inclusion and 7 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 21 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

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?

pregnancy rate (time frame: 6 weeks). 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 21 Jul 2022.
