ClinConnect Summary
This clinical trial is studying a medication called Kyzatrex®, which contains testosterone, to see if it can help menopausal women with a condition called hypoactive sexual desire disorder (HSDD). HSDD is when a woman has little or no interest in sexual activity, which can be distressing. In this study, women aged 30 and older who are menopausal and have low testosterone levels may be eligible to participate. Some key criteria include being in good health with a body mass index (BMI) of 34 or lower and having no significant history of diseases that could affect the study.
Participants in the trial will take a daily capsule of Kyzatrex® for three months. They will visit the research center in San Diego for check-ups, where their blood will be tested several times to monitor safety and how the body processes the medication. They will also have their vital signs measured and be asked about any side effects they might experience. This study is not yet recruiting participants, but it aims to help improve understanding and treatment options for women facing challenges with sexual desire during menopause.
