Uterine Preservation Via Lifestyle Transformation

UPLifT-Endo: Uterine Preservation Via Lifestyle Transformation A Behavioral Intervention to Promote Primary Prevention and Uterine Preservation in Premenopausal Women With Obesity and Atypical Endometrial Hyperplasia or Grade 1 Endometrial Cancer

Uterine Preservation Via Lifestyle Transformation (NCT05903131) is a Phase 2 interventional studying Endometrial Hyperplasia and Grade 1 Endometrial Cancer, sponsored by Washington University School of Medicine. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

Up to 60% of endometrial cancer cases are attributed to obesity, in part because obesity promotes development of atypical endometrial hyperplasia (AEH), and up to 40% of women with AEH go on to develop endometrial cancer. The increasing prevalence of obesity in premenopausal women has resulted in increasing rates of AEH in this age group. Hysterectomy with removal of the fallopian tubes and ovaries is 100% effective in preventing endometrial cancer, but this approach results in infertility. Fertility-sparing treatments exist, such as treatment with oral or intrauterine progestin, but these treatments do not work uniformly and do not combat the underlying cause of endometrial cancer, which is obesity and metabolic syndrome. Additionally, up to 41% of women on progestin eventually experience relapse of AEH or endometrial cancer. Third, many patients have insulin resistance that may worsen with progestin therapy. Thus, to improve treatment of AEH and grade 1 endometrial cancer, prevent and reverse endometrial cancer, and allow women to preserve their fertility, the investigators must integrate an effective weight loss strategy to be given with progestin treatment. It is the hypothesis that premenopausal women with AEH desire uterine preservation will be more likely to have atypia-free uterine preservation at one year if they receive progestin in combination with a behavioral weight loss intervention versus progestin plus enhanced usual care.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Endometrial Hyperplasia and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 96 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Endometrial Hyperplasia subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - Diagnosis of diagnosed by tissue sample (biopsy-confirmed) complex atypical endometrial hyperplasia (AEH) or grade 1 endometrial cancer. - Patients with a previous diagnosis of AEH or grade 1 endometrial cancer who are already being followed with conservative management with oral or LNG-IUD progestin therapy are eligible. - For patients with a previous diagnosis of AEH or grade 1 endometrial cancer who have been placed on progestin prior to study entry, the duration of IUD or oral progestin use prior to trial entry should be documented. - Premenopausal woman with a uterus. - You should be able to carry out daily activities with 0 level of ability (ECOG 0)-2. - At least 18 years of age and no more than 45 years of age. - Undergoing uterine-sparing management (e.g. due to interest in fertility preservation, interest in uterine preservation, provider recommendation, or other reason). - BMI ≥ 30 kg/m\^2. - Prior or current receipt of progestin is allowed as above. Willingness to undergo placement of LNG-IUD at the time of study entry. - Ability to understand and willingness to sign an IRB approved written willing to sign a consent form document. Who Should NOT Join This Trial: - Current, active treatment for any malignant neoplasm with chemotherapy or radiation. - Pregnant and/or breastfeeding. Participants must have a negative urine or serum pregnancy test during screening window and within 7 days prior to LNG-IUD insertion. If LNG-IUD is in place, lack of pregnancy is assumed. - Active pelvic infection at the time of IUD placement or other contraindication to the use of an IUD in the opinion of the treating physician. Always talk to your doctor about whether this trial is right for you.

Bring the printable summary of this trial — including the NCT ID (NCT05903131), the sponsor (Washington University School of Medicine), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?
