| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
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. |
|
| E.2.2 | Secondary objectives of the trial |
To describe correlation between changes in vaginal maturation index and pH and brain activation pattern changes after 3 months of treatment. To describe if there is the correlation between changes in the visual examination of the vagina using the vaginal health index and brain activation pattern changes after 3 months of treatment. To describe the correlation between changes in the questionnaires performed and brain activation pattern changes after 3 months of treatment. To evaluate brain activation patterns after 3 months treatment with ospemifene (VVA ospemifene patients with FSIAD) versus brain activation patterns in these same patients at basal visit. To evaluate if the brain activation patterns after 3 months treatment with ospemifene are similar to the ones observed in women without FSIAD (VVA not treated patients without FSIAD) after 3 months. To evaluate the safety of the treatment with ospemifene 60mg/day and placebo in postmenopausal women with FSIAD. |

| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
Patients have to follow all the inclusion criteria listed below to be included in the study: • Women 40 year old or older who have been diagnosed with menopause (either chemical, surgical or natural menopause) • No menstruation for at least a year. • Moderate or severe VVA diagnosis (defined by the presence of ≤ 5% of superficial cells and vaginal pH > 5). • For homogenisation of brain patterns, women had to be right-handed. • Women should be strictly heterosexual, in a stable relationship of at least 1 year duration (with expectations of remaining with the same relationship), and have had experience viewing sexually explicit images • For the FSIAD groups, women will be included if they are diagnosed with FSIAD, defined according to the criteria of DSM-V and confirmed by a structured clinical interview and by means of the scores of the SFQ and the FSDS-R (with a score of ≤20 for FSFI and ≥15 for the FSDS-R, respectively). These criteria will be an exclusion criterion for women without FSIAD. • Informed written consent of the patient. |
|
| E.4 | Principal exclusion criteria |
• Women with known history of mental illness, history of drug or alcohol abuse. • Women with VVA treatment (oestrogens or ospemifene) at any time during the last 6 months, and/or laser treatment at any time during the last year. • Use of medication or herbal preparations at any time during the last 3 months for the purpose of improving sexual performance. • Women who have received any medication previous to the study inclusion, that may alter or interfere with brain activation patterns (psychoactive drugs). • Women with history of sexual offenses. • Women with abnormal vision that would impair the visualisation of the images and the olfactory stimuli. • Women with claustrophobia or implants that would preclude fMRI procedures. • Women with diagnosis of depression assessed by PHQ self-administered questionnaire. • Patients who had undergone vaginal surgery in the last 12 months. • Women who did not sign the written informed consent. • Hypersensitivity to the active substance or to any of the excipients included in Senshio. • Past or active history of venous thromboembolic events (VTE), including deep vein thrombosis, pulmonary embolism and retinal vein thrombosis. • Unexplained vaginal bleeding. • Patients with suspected breast cancer or who are receiving active treatment (including adjuvant treatment) for breast cancer. • Suspicion of neoplasia or active neoplasia dependent on sex hormones (eg endometrial cancer). • Patients with signs or symptoms of endometrial hyperplasia; In this group of patients, safety has not been studied. |

| E.5 End points |
| E.5.1 | Primary end point(s) |
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. |

|
| E.5.2 | Secondary end point(s) |
• To assess if there is a relation between brain activation pattern changes (blood flow changes in brain areas described measured by t-test) and changes in the vaginal maturation index (percentage of superficial and parabasal cells) as well as vaginal pH after 3 months of treatment. • To assess if there is a relation between brain activation pattern changes (blood flow changes in brain areas described measured by t-test) and changes in the visual examination of the vagina (clinical signs of vaginal dryness, petechiae, pallor, friability, and redness of the mucosa) measured according the vaginal health index after 3 months of treatment. • To assess if there is a relation between brain activation pattern changes (blood flow changes in brain areas described measured by t-test) and changes in the questionnaires: o FSFI questionnaire o DSM V questionnaire o SF-12 (QOL) questionnaire o FSDS-R (Female sexual distress scale-revised) o SFQ (Sexual function) o PHQ (self-reported questionnaire to discard depression) questionnaire after the 3 months of the inclusion in the study. • Describe changes in areas of the brain that will be activated after sexual stimuli (either visual or olfactory) in postmenopausal women with moderate to severe VVA and FSIAD treated with ospemifene for 3 months evaluated by fMRI which will be able to detect changes associated with blood flow versus areas of the brain activated after sexual stimuli (either visual or olfactory) in these same patients at basal visit. The evaluated areas will be the same as for the primary endpoint. • Areas of the brain that will be activated after sexual stimuli (either visual or olfactory) in postmenopausal women with moderate to severe VVA and FSIAD treated with ospemifene for 3 months evaluated by fMRI which will be able to detect changes associated with blood flow versus areas of the brain that will be activated after sexual stimuli (either visual or olfactory) in women without FSIAD (VVA not treated patients without FSIAD). The evaluated areas will be the same as for the primary endpoint. • Adverse events reported during the 3 months of follow-up of the study. |
