Key inclusion & exclusion criteria
|
Inclusion criteria: All subjects 1. Pre-menopausal female subjects aged 18-40. 2. Subjects must personally sign and date the informed consent documentation indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial. 3. Subjects must have been in a stable heterosexual relationship for at least 3 months prior to study start and must remain in a stable relationship throughout the duration of the study. 4. Subjects must be willing and able to comply with scheduled visits, laboratory tests and other trial procedures.
FSAD subject group 5. Subjects must suffer from FSAD that has been present for at least 6 months prior to study entry which may or may not be associated with female orgasmic disorder and/or superficial/introital dyspareunia. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria: All subjects 1. Subjects who are post-menopausal. Post-menopausal status is defined by a documented history of Naturally amenorrhoeic for > 1 year, or A six-month history of amenorrhoea and an FSH level of >50 IU/L and serum estradiol <20 pg/mL, or Bilateral oophorectomy or Subjects who are surgically menopausal. 2. Subjects who have an estradiol plasma concentration of less than 40pg/mL and a free plasma testosterone concentration <0.9pg/mL. Estradiol levels are only required in subjects not taking estrogen-containing oral contraception. 3. Subjects with a recent (past 6 months) history of alcohol or controlled substance abuse. 4. Subjects who have given birth in the previous 6 months, are pregnant, lactating or planning to become pregnant during this study. 5. Subjects with recent (past 3 months) exacerbation of pelvic inflammatory disease, a recent untreated vaginal infection, salpingitis, or other severe or chronic gynecologic disease. 6. Subjects who have had previous surgery to the vagina (including that for stress incontinence or vaginal hysterectomy) and those who have any anatomical abnormality of the vagina. 7. Subjects who have a history of gynaecological malignancy or those with recent abnormal cervical cytology suggestive of neoplastic changes. 8. Subjects who drink more than 21 units of alcohol per week. (1 unit = 285mls of beer or 25ml of spirits or 125ml of wine). 9. Subjects with a history of involuntary movement disorders. 10. Subjects with any clinically significant abnormality following review of pre-study laboratory data and full physical examination. 11. Subjects who, in the opinion of the PI, have any medical or psychological condition or social circumstances which would impair their ability to participate reliably in the study, or who may increase the risk to themselves or others by participating. 12. In the opinion of the investigator, a subject who is not likely to complete the study for what ever reason. FSAD subject group 13. Acceptable contraception includes, but is not limited to; oral contraceptives, IUDs, documented history of surgical sterilization, condoms or partner vasectomy. Unacceptable contraception includes, but is not limited to; withdrawal method, rhythm method or spermicides. (This criterion will only apply to subjects recruited for Part B of the study.) 14. Subjects who suffer from HSDD as determined by the SFQ and subsequent semi-structured interview. 15. Subjects whose sexual dysfunction is considered to be situational, i.e. limited to certain types of stimulation, situation or specific partners. 16. Subjects who have significant dyspareunia, which is due to an inflammatory or anatomical condition (e.g. pelvic inflammatory disease, vulvovestibulitis, fibroids). 17. Subjects who have received treatment for any major psychiatric disorder (e.g. psychosis or hospitalization due to major depression) within the past 12 months. Subjects on SSRIs (selective serotonin re-uptake inhibitors), SNRIs (selective noradrenaline reuptake inhibitors), Tricyclic antidepressants as well as buproprion. 18. Subjects who are currently receiving Hormone Replacement Treatment. 19. Subjects who are currently receiving medication known to interact with NEP-inhibitors such as ACE inhibitors. (This criterion will only apply to subjects recruited for Part B of the study.) 20. Subjects who suffers from hypo– or hypertension (treated as well as untreated) or have a resting supine blood pressure below 90/45mmHg o

Primary Outcome(s)
|
Primary end point(s): Part A: VPA mean change from baseline to mean VSS as measured by VPP. VPA mean change from baseline to maximum level during VSS as measured by VPP.
Part B: VPA mean change from pre-dose baseline to mean VSS as measured by VPP. VPA mean change from pre-dose baseline to maximum level during VSS as measured by VPP.
|
Secondary Objective: Part A: To assess the degree of undesirable artefacts and fluctuations in the vaginal pulse amplitude (VPA) traces. To assess the variability of subjective feeling of arousal at baseline and during visual sexual stimulation (VSS). To investigate differences in VPA between healthy volunteers and subjects suffering from FSAD. Part B: To investigate the suitability of this technique in determining sensitivity to change on VBF following dosing with UK-447,841.To assess the correlation between changes in VPA and subjective feeling of arousal during sexual arousal.To investigate the safety and toleration of single oral doses of UK-447,841 in FSAD subjects.To determine plasma concentrations of UK-447,841 in FSAD subjects. To determine the effect of UK-447,841 on levels of plasma biomarkers such as VIP, ANP, big endothelin and cGMP.
|
Main Objective: Part A: Primary:To investigate the reproducibility of the vaginal photoplethysmography (VPP) technique in healthy pre-menopausal female volunteers and pre-menopausal subjects suffering from FSAD. Part B: Primary: To investigate the effect of single doses of UK-447,841 on vaginal blood flow (VBF) as measured by VPP in pre-menopausal subjects suffering from FSAD.
