Efficacy and Tolerance of an Ovarian Stimulation Protocol Combining Follicle Stimulating Hormone (FSH) and Degarelix Acetate in Female Candidates for Fertility Preservation Before Chemotherapy for Breast Cancer
France8 participantsStarted 2019-11-28
Plain-language summary
The present investigation aims to evaluate the efficacy of an innovative protocol of controlled ovarian stimulation for breast cancer patients, who are candidates for fertility preservation.
Currently, vitrification of oocytes and/or embryos after controlled ovarian stimulation is the most established method for female fertility preservation. However, this stimulation induces an increase in serum estrogen levels, which is theoretically problematic in case of hormone-sensitive tumors such as breast cancer. The majority of oncology teams accept, in very specific situations (particularly when the tumor has been surgically removed), this ovarian stimulation, because the expected benefits of fertility preservation far outweigh the risks. However, everyone agrees that it would be more comfortable to be able to offer vitrification of oocytes and/or embryos using ovarian stimulation without increasing estrogen levels.
In this research, investigators will evaluate the efficacy of degarelix (Firmagon®), currently indicated for the treatment of prostate cancer, as an innovative ovarian stimulation procedure. Administered at the beginning of ovarian stimulation, they believe it should maintain serum estradiol levels at physiological values at the end of stimulation.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
