About this study

Official title: Comparison of Standard and Physiologic Sex Steroid Replacement Regimens in Women With Premature Ovarian Failure and the Assessment of Skeletal, Cardiovascular and Reproductive Parameters

The aim of the study is to determine whether physiological sex steroid replacement improves parameters of skeletal, cardiovascular and reproductive health of women treated with current sex steroid replacement regimens.

Read the detailed description

Premature ovarian failure, defined as the onset of the menopause before the age of 40 years, is a relatively common problem that affects 1% of women. There are a variety of aetiologies underlying premature ovarian failure including Turner syndrome and those with idiopathic onset, however with the increasing success of intensive treatment for childhood cancer, there are increasing numbers of young survivors, with a variety of late effects of treatment, including premature ovarian failure.

Evidence is required for the optimal management of young women with premature ovarian failure, either as a result of childhood cancer treatment or for other reasons. These women are currently offered combined sex steroid replacement in the convenient form of the oral contraceptive pill, or hormone replacement therapy, designed for older women after the menopause. These preparations are not designed to achieve physiological replacement of oestrogen or progesterone, either in dosage or in biochemical structure - many preparations using synthetic derivatives. These younger women who have differing metabolic and psychological requirements are looking to a future of 30 or more years of replacement. The optimal mode of SSR is not known for young women with premature ovarian failure, however there is concern that current regimens may be inadequate for optimal skeletal and cardiovascular health.

Current preliminary data demonstrates that use of physiological sex steroid replacement improves uterine parameters. Evidence is required to determine whether optimising sex steroid replacement can also significantly improve parameters of skeletal and cardiovascular health. Young women with ovarian failure face several decades of hormone replacement, so small improvements in management may make large differences to later morbidity and mortality.

The aim of the study is to determine whether physiological sex steroid replacement improves parameters of skeletal, cardiovascular and reproductive health of women treated with current sex steroid replacement regimens.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ethinylestradiol / Norethisterone and Estradiol / Progesterone in people with Premature Ovarian Failure, run by University of Edinburgh at 2 sites in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Aug 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in 24 hour ambulatory blood pressure (time frame: Before each washout period, then at 0, 3, 6 and 12 months of each treatment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00732693, which also lists 15 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2008.
