Clinical Trial Summary

During menopause a woman's body slowly produces less of the hormones estrogen and progesterone. Lower hormone levels in menopause may lead to hot flashes, vaginal dryness and osteoporosis. To help with these problems, women are often given estrogen or estrogen with progestin. The purpose of this study is to assess and compare the efficacy and safety of three doses of estradiol and progesterone for the treatment of the climacteric symptoms


Clinical Trial Description

Different formulations of estrogens and progestins have been used for the treatment of climacteric symptoms, however up to this date no formulation is completely satisfactory. Our company has developed a new technology for the preparation of controlled release bioerodible non-polymeric microspheres, these microspheres are capable of delivering doses of estradiol (E) and progesterone (P) at levels appropriate for the Hormonal Replacement Therapy (HRT) in order to relieve the climacteric symptoms. Non clinical and clinical studies have been conducted aimed at assessing the pharmacokinetics of these microspheres, at several doses of progesterone and estradiol. Results show that sustained plasma profiles for both steroids within the therapeutic range for several days are attained. On this basis, a new efficacy and safety study is going to be conducted with the purpose of assessing and defining the most appropriate doses of estradiol and progesterone for the HRT of the climacteric symptoms.

Three different doses of progesterone and estradiol (0.5 mg of E + 15 mg of P vs 1 mg of E + 20 mg of P vs 1 mg of E + 30 mg of P) will be compared in terms of their efficacy and safety to treat the climacteric symptoms in healthy postmenopausal women. ;
