Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a one treatment arm study, where Estradiol valerate, will be given as a daily oral dose of a 1 or 2 mg tablet for 8 weeks prior to scheduled hysterectomy. An initial trial of 5 patients with 1 mg dose will be undertaken to determine if this low dose is sufficient to regenerate the endometrium. If inadequate, the 2 mg dose will be used.

If the patient is already on hormone replacement therapy (ie 1 mg oral estradiol valerate, 1 mg oral micronized estradiol, 0.325 mg oral conjugated equine estrogens), the progestin component will be stopped and the patient will continue with the original estrogen alone for 8 weeks prior to hysterectomy

Eligibility
Key inclusion criteria
Postmenopausal women who have not had a period for >12 months who are scheduled to undergo hysterectomy for treatment of their underlying clinical condition, usually for pelvic organ prolapse but may include other indications (eg fibroids, menorrhagia).

Women already on hormone replacement therapy will be recruited and if appropriate, the estrogen component will be changed to estradiol valerate without a progestogen.
Minimum age
45 Years
Maximum age
69 Years

Undiagnosed abnormal genital bleeding.
Known, suspected, or history of cancer of the breast..
Known or suspected estrogen-dependent neoplasia.
Current or past history of deep vein thrombosis, pulmonary embolism, or a known coagulopathy.a history of these conditions.
Active or recent (within the past year) arterial thromboembolic disease (for example, stroke, myocardial infarction); uncontrolled hypertension.

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Dr Anna Rosamilia will identify potential eligible participants seeking treatment for their urogynaecogical problem at Southern Health, Cabrini or Waverley Private Hospitals. A urogynaecologist is required for obtaining participation as it is necessary for her to diagnose that the patient requires a hysterectomy as part of the treatment for her clinical condition. Furthermore, a gynaecologist is required to determine the suitability of potential participants with respect to exclusion criteria for treatment with estradiol valerate (Progynova) and subsequent monitoring of these participants.

Summary
Brief summary
This phase 4 clinical trial is to determine whether estradiol valerate (1 or 2 mg daily for 8 weeks prior to hysterectomy) will regenerate the endometrium from postmenopausal women sufficiently to enable endometrial mesenchymal stem cells to be isolated from a biopsy taken during surgery just prior to surgical removal of the uterus. It is a proof-of-principle study to determine if endometrial stem cells can be isolated from postmenopausal women for potential autologous use in tissue engineering as a construct for pelvic organ prolapse repair surgery.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
This is a scientific study that is still in development for a potential future therapy for treating pelvic organ prolapse. It did not test a cell-therapy in women. It simply enabled us to show proof of principle that we could harvest the cells from postmenopausal women whose endometrium is atrophic.
