Menopause Clinical Trial
Official title:
Pharmacokinetic, Clinical, Hormonal and Therapeutic Effects of the Use of Estradiol and Testosterone Hormonal Subdermal Implants in Women With Natural Menopause, Premature Ovarian Failure or Surgical Menopause Due to Cervical Cancer.
Estrogen and androgen deficiencies negatively impact the quality of life of women at different stages of life, especially after menopause. New modalities and new therapeutic alternatives have been researched. Parenteral administration of estradiol and testosterone could be effective to treat symptoms secondary to estrogen and androgen deficiencies and minimize these adverse events. This study evaluates the efficiency of subdermal implant-bioabsorbable use in women with menopausal symptoms associated with secondary estrogen and androgen deficiencies in women with natural menopause, premature ovarian failure or surgical menopause due to cervical cancer. Pharmacokinetic, biochemical, metabolic, thromboembolic and hormonal data will be evaluated, as well as the effects on quality of life, menopausal symptoms and sexual function after treatment.
The clinical study will be carried out on 140 women, who will be divided into three groups: (1) postmenopausal women with menopausal and sexual symptoms (n=60); (2) women with premature ovarian failure (n=40); (3) women with cervical cancer undergoing abdominal hysterectomy with bilateral adnexectomy, with menopausal and sexual symptoms (n=40). All participants will answer questionnaires to assess quality of life, menopausal symptoms and sexual function. All participants will undergo general physical and gynecological examinations, as well as hormonal, biochemical, thromboembolic and imaging tests. The study will last six months. The included participants will undergo the following visits: inclusion (post-selection) and 1, 3 and 6 months after implant insertion. For the pharmacokinetic study, blood samples will be collected at the following periods: inclusion (before implant placement) and after 1h, 2h, 3h, 6h and 12h; one week, two weeks and one month after placement, and then monthly until six months after implant insertion, to evaluate serum levels of Luteinizing hormone, Follicle stimulating hormone, estradiol, estrone, total testosterone and sex hormone-binding globulin. Clinical, biochemical, hormonal and therapeutic parameters will be evaluated before placement (inclusion) and after 3 and 6 months. The Mann Whitney test will be applied to evaluate differences between measurements and the chi-square test will be applied to analyze the proportions of improvement between groups before and after treatment. ;
