Lybrido for Female Sexual Dysfunction
Overview[ - collapse ][ - ]
| Purpose | The Lybrido study is a double-blind, randomized, placebo-controlled study with a 4-week baseline establishment period, 16 week treatment period and a follow up period for a total of 26 weeks on study. Subjects are randomly to one of seven treatment arms. The study investigates the effective dose of Lybrido in increasing the number of satisfactory sexual episodes in the domestic setting in 210 healthy female subjects with hypoactive sexual desire disorder and low sensitivity for sexual cues (30 subjects per group). |

| Current Primary Outcome Measures | The number of satisfactory sexual encounters based on event questionnaires on active drug as compared to placebo during double-blind treatment period episodes in the domestic setting. [Time Frame: 20 weeks] [Designated as safety issue: No]Efficacy is estimated by self reporting by subjects using daily event questionnaires, recorded within 24 hours after a sexual event. The number of events between a 4-week baseline establishment period will be compared with the number of events during the 8 week double-blind treatment period. In addition there is a 8 week run in period between the establishment period and the double blind treatment period for a total treatment period of 20 weeks. |

History of myocardial infarction, stroke, transient ischemic attack, or life-threatening arrhythmia within the prior 6 months 3. Uncontrolled atrial fibrillation/flutter at screening or other significant abnormality observed on electrocardiogram (ECG) 4. Systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure > 90 mmHg. For subjects > 60 years old and without diabetes mellitus, familial hypercholesterolemia, or cardiovascular disease: systolic blood pressure ≥ 160 mmHg and/or diastolic blood pressure > 90 mmHg 5. Systolic blood pressure < 90 mmHg and/or diastolic blood pressure < 50 mmHg 6. Use of oral contraceptive containing anti-androgens 7. Use of oral contraceptive containing 50 μg estrogen or more 8.

Lactating or delivery in the previous 6 months 11. Significant abnormal pap smear in the previous 12 months 12. History of bilateral oophorectomy 13. Other unexplained gynecological complaints, such as clinically relevant abnormal uterine bleeding patterns 14.

Current clinically relevant endocrine disease or uncontrolled diabetes mellitus 16. Current clinically relevant neurological disease which, in the opinion of the investigator, would compromise the validity of study results, or which could form a contraindication for sildenafil and/or testosterone use 17. History of hormone-dependent malignancy 18. Vision impairment, such as partial or complete blindness or color blindness 19. Dyslexia 20. Positive test result for human immunodeficiency virus, hepatitis B, or hepatitis C (acute and chronic hepatitis infection) 21. History of (childhood) sexual abuse that, in the opinion of the investigator, could have negative psychological effects when testosterone is administered 22. (Treatment for) a psychiatric disorder that, in the opinion of the investigator, would compromise the validity of study results or which could be a contraindication for sildenafil and/or testosterone use 23. Current psychotherapeutic treatment for female sexual dysfunction 24. Current sexual disorder of vaginismus or dyspareunia according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (text revision). 25. A substance abuse disorder that, in the opinion of the investigator, is likely to affect the subject's ability to complete the study or precludes the subject's participation in the study (Mild or moderate alcohol consumption is allowed but must be stopped 12 hours before the home measurement [Stroop task].) 26. Positive test result for illicit drugs 27. Use of potent CYP3A4 inhibitors (eg, ritonavir, ketoconazole, itraconazole clarithromycin, erythromycin and saquinavir) 28.

Use of any other medication that interferes with study medication (eg, monoamine oxidase [MAO] inhibitors [includes classic MAO inhibitors and linezolid]) 32. Use of medication (including herbs) that would compromise the validity of study results 33. Use of testosterone therapy within 6 months before study entry 34. Illiteracy, unwillingness, or inability to follow study procedures 35. Participation in other clinical trials within the last 30 days 36. Any other clinically significant abnormality or condition which, in the opinion of the investigator, might interfere with the participant‟s ability to provide informed consent or comply with study instructions, compromise the validity of study results, or be a contraindication for sildenafil and/or testosterone use |
