About this study

Official title: Comparing Metformin Plus Megestrol Acetate with Megestrol Acetate Alone As a Fertility-sparing Treatment in Patients with Atypical Endometrial Hyperplasia

To verify whether metformin could improve the effect of progestin as fertility-sparing treatment in patients with atypical endometrial hyperplasia(AEH).

Read the detailed description

Whether metformin could improve the effect of progestin as fertility-sparing treatment in patients with atypical endometrial hyperplasia(AEH) is still not clear. Our previous finding from subgroup analysis in a phase II randomized controlled trial showed that 39.6% of AEH patients in metformin plus megestrol acetate group achieved complete response, compared with 20.4% in group of megestrol acetate alone. This trial aim to fully testify the effect of metformin in fertility-sparing treatment for AEH patients with adequate sample size.

Why it stopped: Our clinical trial NCT03241888 showed LNG-IUS had a better treatment efficacy than Megestrol Acetate (MA) alone. The median CR time for MA group, LNG-IUS group and MA plus LNG-IUS group was 7.0±0.3 months, 4.4±1.0 months and 5.7±1.2 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Metformin plus Megestrol acetate and Megestrol Acetate in people with Atypical Endometrial Hyperplasia, run by Fudan University 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 8 inclusion and 8 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: stopped early, as of the sponsor's last update on 26 Sep 2024. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The study was stopped early (reason given: Our clinical trial NCT03241888 showed LNG-IUS had a better treatment efficacy than Megestrol Acetate (MA) alone. The median CR time for MA group, LNG-IUS group and MA plus LNG-IUS group was 7.0±0.3 months, 4.4±1.0 months and 5.7±1.2 months.). 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?

Complete response within 16 weeks of treatment (time frame: 16 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 26 Sep 2024.
