About this study

Ospemifene is the first oral and non-hormonal treatment for moderate or severe vulvo-vaginal atrophy (VVA) in postmenopausal women who are not candidates to treatment with local oestrogens. Its effects are mediated though the regeneration of the proportion of superficial and intermediate cells of the vagina, improving menopausal symptomatology such as dryness and dyspareunia.

Only two studies to date have directly compared brain activation patterns in women with normal sexual function with women complaining with hypoactive sexual desire disorder. Arnow et al. demonstrated that women with normal sexual function showed brain activations in multiple regions different from women with FSIAD. When comparing the two groups, women with normal sexual function showed greater activation of the bilateral entorhinal cortex while women with FSIAD exhibited greater activation of the medial frontal gyrus, right inferior frontal gyrus, and bilateral putamen. The medial frontal gyrus activation has been associated with self-monitoring; thus, it is possible that women with FSIAD allocate more attention to monitoring their response, which may be inhibitory to sexual functioning. The other study was done by Woodard and colleges showing that women with normal sexual function showed significantly differences on cerebral activation in comparison with women with FSIAD.

These differences observed in women with FSIAD could suggest that they may have alterations in activation of limbic and cortical structures responsible for acquiring, encoding, and retrieving memory, the processing and memory of emotional reactions, and areas responsible for heightened attention to one's own physical state.

For this reason the authors believe that it is essential to determine if the effect of ospemifene on the improvement on sexual function is due to the improvement on the vagina tract or due to its effect on brain function.

Read the detailed description

To evaluate changes from baseline in brain activation patterns, by using functional magnetic resonance imaging (fMRI) techniques and sexual stimuli, in postmenopausal women with moderate to severe vulvovaginal atrophy and FSIAD after 3 months treatment with ospemifene 60mg/day compared to those treated with placebo. fMRI technique allows the study of brain activation by detecting brain blood flow and oxygen level dependent changes induced by neuronal activation.

The brain activation patterns will be defined by the number of voxels that significantly changed their signal intensity during the stimuli presentation compared to the neutral stimuli. Brain connectivity will be evaluated by using the activation map and the atlas of neuroanatomic regions and comparing the number of voxels, its level of significance and the different regions activated.

Brain activation patterns changes (with fMRI) after sexual stimuli (visual or olfactive), in postmenopausal women with moderate to severe VVA and FSIAD after 3 months treatment with ospemifene 60mg/day compared to those treated with placebo.

During the fMRI session, the activation of each brain circuits/pattern is measured by the blood-oxygen level dependent (BOLD) signal and with the Statistical Parametric Mapping method regularly used in fMRI studies to visualize brain activation.

For the longitudinal study, a paired t-test will be used within each group to detect changes in activation over time. The statistical threshold criterion to compare the different activation maps between both groups is p < 0.001 uncorrected with a minimum extent of 10 voxels. Only clusters that survive a p < 0.05 FWE (family wise error) correction for multiple comparisons will be considered statistically significant The region of interests who were mainly observed are: medial occipital gyrus, anterior cingulate cortex, bilateral thalamus, caudate nucleus, left pale globe, cerebellum, left inferior parietal lobe, postcentral gyrus, praecuneus, right medial frontal gyrus and left praecuneus.

A total of 20 consecutive postmenopausal women with moderate to severe VVA and FSIAD with symptomatology will be recruited to participate in the study, 10 of which will be randomised to the ospemifene group (VVA-FSIAD ospemifene group) and 10 will be randomised to the placebo group (VVA-FSIAD placebo group). Additionally, a total of 5 consecutive postmenopausal women with moderate to severe VVA not treated with ospemifene neither with any other VVA treatment and without FSIAD will also be recruited (VVA not treated patients without FSIAD).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ospemifene 60 mg and fMRI experiments in people with Vulvovaginal Signs and Symptoms and Genitourinary Syndrome of Menopause, run by Hospital Clinic of Barcelona at 1 site in Spain.

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 7 inclusion and 16 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 15 Sep 2025. 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 Spain. 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. Some participants in this study may receive a placebo. 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?

a Activation of each brain circuits (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Sep 2025.
