The Role of Granulocyte Colony Stimulating Factor in Embryo Transfer Outcomes
Canada300 participantsStarted 2024-03-20
Plain-language summary
The goal of this clinical trial is to test the effect of granulocyte colony-stimulating factor (G-CSF, A.K.A. Filgrastim) in infertility patients undergoing in vitro fertilization (IVF) treatment. The main question it aims to answer is:
Can in vitro fertilization-embryo transfer (IVF-ET) outcomes be improved by supplementing the transfer media with Granulocyte colony-stimulating factor (GCSF)?
Participants will undergo their embryo transfer as per the normal clinic protocol but will be randomized to either receive the standard embryo transfer media or the GCSG-supplemented transfer media.
Researchers will compare the GCSF and standard transfer media groups to see if clinical outcomes are improved (i.e., implantation rate, pregnancy, clinical pregnancy rate, live birth rate).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Recruited subjects will either be undergoing a fresh IVF-ET cycle in which the embryo(s) generated from the initial treatment cycle are transferred during that same cycle (i.e., on day 5 or 6 post-egg retrieval) or an FET cycle in which the embryo(s) transferred were generated in a previous IVF cycle and were cryopreserved for subsequent warming and transfer.
Exclusion Criteria:
* Patients with uterine factor or severe male factor infertility will be excluded.
* Patients who have had previous IVF failures will be excluded.
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?

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.
