Bilateral Oophorectomy Versus Ovarian Conservation

August 4, 2011 updated by: University of California, San Francisco

Elective Bilateral Salpingo-oophorectomy Versus Ovarian Conservation: A Pilot Randomized, Controlled Trial

This is a pilot study to assess the feasibility of conducting a randomized, blinded, controlled trial of bilateral salpingo-oophorectomy (BSO, removal of the ovaries and fallopian tubes) versus ovarian conservation among premenopausal women age 40 years and greater who plan to undergo hysterectomy for a benign gynecologic condition. Subjects will be randomized to BSO or ovarian conservation concomitant with hysterectomy and remain blinded to group assignment. The primary goal of this pilot is to determine the feasibility of recruiting and retaining study participants in anticipation of conducting a larger, multi-centered trial. However, the investigators will also obtain baseline data and follow-up measures at 6 weeks and 6 months after surgery. Outcomes will be assessed in several domains that the investigators hypothesize may be effected by oophorectomy: cardiovascular health, skeletal health, sexual functioning, and health-related quality-of-life.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 1, 2009

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
