About this study

Official title: Effectiveness and Safety of Gabapentin for the Treatment of Hot Flashes in Menopausal Women: A Randomized Controlled Trial

The purpose of this study is to evaluate the effectiveness and safety of gabapentin compared to placebo in the treatment of hot flashes in postmenopausal women using a phase III randomized controlled trial.

Read the detailed description

For women who fear developing breast cancer, those who have contraindications to hormone replacement therapy and those who prefer an alternative treatment, there is presently no standard treatment for hot flashes. Women and health care providers have few options other than hormone replacement therapy as evidenced-based trials of alternatives have not shown many effective options. Many non-hormonal agents have been studied including antidepressants, antihypertensives, vitamin E, soy products, black cohosh, acupuncture, and belladonna and ergotamine combinations. Preliminary studies using the antiseizure medication, gabapentin (Neurontin), has demonstrated a substantial reduction in hot flashes. This agent may provide an effective treatment for hot flashes in postmenopausal women.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing gabapentin in people with Hot Flashes and Menopause, run by North Toronto Primary Care Research Network at 1 site in Canada.

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 3 inclusion and 10 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 23 May 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Compared to placebo, gabapentin effectiveness in reducing hot flash scores in postmenopausal women. 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 NCT00112138, which also lists 1 linked publication.

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 23 May 2011.
