Raloxifene and Rimostil for Perimenopause-Related Depression

Study Summary

The purpose of this study is to evaluate the effectiveness of the drugs raloxifene and rimostil in treating perimenopause-related depression. Perimenopause-related mood disorders cause significant distress to a large number of women; the demand for effective therapies to treat these mood disorders is considerable. Estradiol replacement therapy (ERT) has demonstrated efficacy in treating perimenopause-related depression. Unfortunately, there are long-term risks associated with ERT. Selective estrogen receptor modulators (SERMS), such as raloxifene, and phytoestrogens, such as rimostil, have estrogen-like properties and may offer a safer alternative to ERT. The effect of SERMS and phytoestrogens on mood and cognitive functioning need to be examined in women with perimenopause-related depression. Participants in this study will undergo a medical history, physical examination, electrocardiogram (EKG), and blood and urine tests. They will then be randomly assigned to receive one of four treatments for 8 weeks: raloxifene pills plus a placebo (an inactive substance) skin patch, rimostil pills plus placebo skin patch, estradiol skin patch plus placebo pills, or placebo patch plus placebo pills. Participants will have clinic visits every 2 weeks. During the visits, blood will be drawn and participants will meet with staff members and complete symptom self-rating scales. A urine and blood sample will be collected at the beginning and end of the study. At the end of the study, participants who received placebo or whose study medication was ineffective will be offered treatment with standard antidepressant medications for 8 weeks. Non-menstruating women will receive progesterone for 10 days to induce menstrual bleeding and shedding of the inner layer of the uterus, which may have been stimulated by the study medications.

Primary Outcome

Center for Epidemiologic Studies-Depression Scale (CES-D) cutoff scores are typically used as a screen to identify clinically significant depression; a cutoff score of greater than 16 has been shown to correlate with clinically significant depression. In addition, a score between 8 and 15 has been used to define subsyndromal depression. The possible range of scores is zero to 60, with the higher scores indicating more symptoms, weighted by frequency of occurrence during the past week.
