Semaglutide, Weight Loss, and LNG-IUD for Conservative Treatment of Endometrial Atypical Hyperplasia and Grade 1 Endometrial Cancer (SWIFT)
SEMAGLUTIDE, WEIGHT LOSS, AND INTRAUTERINE THERAPY FOR FERTILITY-SPARING AND CONSERVATIVE TREATMENT FOR ENDOMETRIAL ATYPICAL HYPERPLASIA AND EARLY-STAGE, GRADE 1 ENDOMETRIOID ENDOMETRIAL CANCER
The goal of this clinical trial is to learn if a combination treatment of a hormonal intrauterine device (LNG-IUD), semaglutide, and a structured weight loss program can treat endometrial atypical hyperplasia or grade 1 endometrioid endometrial cancer while preserving fertility in women of reproductive age with endometrial atypical hyperplasia (EAH) or FIGO grade 1 endometrioid endometrial cancer who wish to preserve their fertility. The main questions it aims to answer are:
- What proportion of participants achieve a complete pathological response after treatment?
- How durable is the response at 12 months?
- What effect does the treatment have on metabolic outcomes (weight, BMI, HbA1c) and quality of life?
Participants will:
- Receive an LNG-IUD
- Receive semaglutide 2.4mg
- Participate in a structured weight loss program
- Undergo hysteroscopy with endometrial sampling to assess treatment response
- Complete quality-of-life assessments at baseline, 6 months, and 12 months

Beskrivelse
Inclusion Criteria:
- Histological Diagnosis: Histologically confirmed endometrial atypical hyperplasia or FIGO grade 1 endometrioid Endometrial Cancer
Imaging eligibility (for patients with endometrial cancer):
- Depth of myometrial invasion <50% confirmed by MRI or disease limited to the endometrium
- No evidence of extrauterine or metastatic disease on imaging.
Treatment Rationale (at least one of the following must apply):
- Desire for future fertility: Patient expresses a documented desire to preserve the uterus and future reproductive function, with explicit acknowledgment that fertility-sparing treatment is not standard of care for endometrial cancer.
- Medical inoperability: patients are considered a poor surgical candidate due to:
i. Class III obesity (BMI ≥40 kg/m²); or ii. ASA Physical Status Classification score ≥3.
- Metabolic Profile: BMI ≥ 30 kg/m², or BMI 27-29.9 kg/m² with at least one weight-related comorbidity (hypertension, type 2 diabetes mellitus, dyslipidemia, obstructive sleep apnea, or non-alcoholic fatty liver disease).
Progestin washout: patients with prior progestin exposure are eligible provided the following minimum washout periods have been observed.
- Oral progestins: 7 days
- Injectable, short acting: 14 days
- Injectable, long acting: 6 months
- Contraceptive implant: 28 days
- LNG-IUD: 7 days after removal
Exclusion Criteria:
- Age ≥18 years
- Negative pregnancy test at screening
- Ability to provide written informed consent and comply with study procedures
- Willingness to undergo genetic counseling and MMR/IHC tumor profiling
- Willingness and ability to participate in a structured weight loss program, including attendance at counseling sessions (in person or virtual) and adherence to dietary and physical activity goals.

Eksperimentel: Combination Fertility-Sparing Treatment
Participants will receive a three-component combination intervention consisting of: (1) a levonorgestrel-releasing intrauterine device (LNG-IUD), inserted at baseline; (2) semaglutide 2.4 mg, administered per standard dosing schedule; and (3) a structured weight loss program.
Participants will undergo hysteroscopy with endometrial sampling to assess pathological response.
Treatment will be administered for 6 months of active intervention, followed by a 6-month follow-up period.
|
Semaglutide 2.4 mg administered subcutaneously once weekly, following standard dose-escalation protocol, for the duration of the 6-month active treatment period.
Used off-label in this trial for its metabolic effects in combination with LNG-IUD, rather than as monotherapy for weight loss.
Levonorgestrel-releasing intrauterine device inserted at study baseline and maintained through the active treatment and follow-up periods, providing continuous local progestin delivery to the endometrium in combination with systemic semaglutide.
A structured, protocol-defined weight loss program combining dietary counseling and physical activity guidance, delivered concurrently with pharmacologic and device-based treatment to support metabolic response, distinct from weight loss achieved through semaglutide alone.
