Semaglutide, Weight Loss, and LNG-IUD for Conservative Treatment of Endometrial Atypical Hyperplasia and Grade 1 Endometrial Cancer (SWIFT)

9 de septiembre de 2026 actualizado por: Aparna A. Kamat, The Methodist Hospital Research Institute

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

Descripción

Inclusion Criteria:

  1. Histological Diagnosis: Histologically confirmed endometrial atypical hyperplasia or FIGO grade 1 endometrioid Endometrial Cancer
  2. Imaging eligibility (for patients with endometrial cancer):

    1. Depth of myometrial invasion <50% confirmed by MRI or disease limited to the endometrium
    2. No evidence of extrauterine or metastatic disease on imaging.
  3. Treatment Rationale (at least one of the following must apply):

    1. 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.
    2. 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.

  4. 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).
  5. Progestin washout: patients with prior progestin exposure are eligible provided the following minimum washout periods have been observed.

    1. Oral progestins: 7 days
    2. Injectable, short acting: 14 days
    3. Injectable, long acting: 6 months
    4. Contraceptive implant: 28 days
    5. LNG-IUD: 7 days after removal

Exclusion Criteria:

  1. Age ≥18 years
  2. Negative pregnancy test at screening
  3. Ability to provide written informed consent and comply with study procedures
  4. Willingness to undergo genetic counseling and MMR/IHC tumor profiling
  5. 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.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Experimental: 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.
