Preservation of Ovarian Function clinical trials

Effect of Cetrorelex Acetate on Ovarian Function in Women Undergoing Chemotherapy

This study will examine whether the drug cetrorelex acetate (Cetrotide[Registed Trademark]) can protect ovarian function in women undergoing chemotherapy. Some cancer treatments are known to cause a change in women's periods or to cause menstruation to stop completely, so that they cannot become pregnant. Cetrorelex acetate has been used for many years to lower hormone levels and stop periods in patients undergoing in vitro fertilization treatments. This study will see if making the ovaries inactive may protect them from being affected by certain cancer drugs, and thus preserve fertility. Women up to age 21who have begun menstruating, who have their uterus and at least one functioning ovary, and who are undergoing chemotherapy with cyclophosphamide, busulfan, nitrogen mustard or L-phenalanin mustard may be eligible for this study. Participants undergo the following procedures during this 24-month study: Baseline evaluation - Medical history, physical examination and blood and urine tests - Questionnaire about quality of life, menstrual periods, vaginal bleeding and desire for future fertility - 3D ultrasound of abdomen - DEXA scan to evaluate bone density Assignment to treatment with: - Lo ovral (contraceptive pill to prevent pregnancy and control menstrual periods) alone, or - Lo ovral and the study drug cetrorelex acetate, given as an injection under the skin once a day for six menstrual cycles Evaluations - Transvaginal 3D ultrasound to monitor changes in the ovary - after 6 months of cetrorelex acetate injections - DEXA scan - after 6 months of cetrorelex acetate injections - Blood tests for safety monitoring, pregnancy testing, endocrine tests and research uses - every 3 months during first year, every 6 months during second year - Questionnaire to monitor changes and quality of life - every 3 months during first year, every 6 months during second year.
