Prospective Clinical Study of Nintedanib to Inhibit Endometrial Fibrosis to Prevent Recurrence of Uterine Adhesions

November 22, 2022 updated by: Sixth Affiliated Hospital, Sun Yat-sen University
In moderate to severe cavity adhesions, the endometrial basal layer is more severely damaged and the regenerative capacity of the endometrium and glands is low. Even though hysteroscopic electrosurgery can roughly restore the cavity morphology, the postoperative recurrence rate is as high as 40%. Abnormal uterine cavity morphology and poor endometrial repair often lead to repeated cancellation of embryo transfer cycles in assisted reproduction treatment, and reduced clinical pregnancy rate, causing mental stress and financial burden to patients, which is one of the current problems in clinically assisted reproduction treatment. Nintedanib is a triple vascular kinase inhibitor that acts primarily on platelet-derived growth factor receptor (PDGFR) and fibroblast growth factor receptor (FGFR) and has been approved by the FDA for the clinical treatment of idiopathic pulmonary fibrosis and systemic sclerosis. The investigator's preliminary animal study found that endometrial fibrosis was significantly reduced in mice with gastric feeding of nintedanib in uterine adhesion molds. This study aimed to clarify further the role of nintedanib in inhibiting endometrial fibrosis and its clinical application value.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The experiment will be divided into two groups based on the dose administered. After hysteroscopic surgery, one group will be given Nedanib 100mg bid orally for 15 days and the other group will be given Nedanib 150mg bid orally for 15 days. Hysteroscopic AFS scores and endometrial tissues before and after treatment will be collected for molecular biology experiments.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

  • Phase 3

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 38 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female
