Recruiting studies
- NCT06212102RecruitingPhase 2
Comparing two drugs for poor responders in double ovarian stimulation
This trial compares dydrogesterone with a GnRH antagonist to see which works better for women with a low number of eggs (poor responders) who are undergoing two rounds of egg retrieval in one cycle. It may help improve outcomes for those with specific fertility challenges.
Cairo, Cairo GovernorateAges 35–44 - NCT05847283Recruiting
Freeze-all IVF approach for low egg reserve
This trial compares two hormone injection protocols to help women with low egg supply grow eggs and collect eggs for IVF. If you qualify, your embryos will be frozen first (“freeze-all”) and then transferred later as one frozen blastocyst.
Hanoi, HanoiAges 18–37 - NCT06531499RecruitingPhase 1
Study of a radioactive drug for advanced prostate cancer
This trial tests an extended treatment with a radioactive drug (177Lu-PSMA-617) to see how the body handles it, how safe it is, and how well it works. It is for men with metastatic castration-resistant prostate cancer who have not had chemotherapy yet.
Los Angeles, CaliforniaAges 18–100 - NCT07620067Recruiting
GnRH Hormone for IVF Embryo Support
This study tests whether a hormone called GnRH can improve success rates during IVF (in vitro fertilization) by supporting the embryo after transfer. If you're having IVF for the first to third time and your doctor is considering different support methods, this trial may explore options for you.
JerusalemAges 18–45 - NCT07771283Enrolling by invitation
Comparing ovarian stimulation methods for IVF
This study compares two methods of stimulating the ovaries before IVF: one using a standard hormone (hCG) and another using a different protocol. The goal is to see if the new method works as well as the standard one, while possibly being more cost-effective.
KampalaAges 18–40 - NCT07409493Recruiting
Comparing two IVF methods with time-lapse imaging
This study compares two types of ovarian stimulation protocols (PPOS and GnRH antagonist) for women undergoing IVF with a freeze-all embryo plan. It uses time-lapse imaging to see if one approach leads to better embryo development.
HanoiAges 20–45 - NCT07394530Recruiting
Comparing two IVF stimulation methods for women with PCOS
This trial compares two types of ovarian stimulation protocols (PPOS and antagonist) for women with PCOS undergoing IVF to see which leads to better outcomes. If you have PCOS and are planning IVF, this study may help find the best approach for you.
Hanoi, HanoiAges 18–40 - NCT06023602Recruiting
Generic vs. brand-name cetrorelix for IVF ovarian stimulation
This trial compares a generic version of cetrorelix acetate (a medication used to control ovulation) to the brand-name version during IVF. It aims to see if the generic works just as well for women undergoing ovarian stimulation.
Xi'an, None SelectedAges 20–42 - NCT05447208RecruitingPhase 3
Testing growth hormone to improve embryo chromosome screening results
This Phase 3 study tests whether growth hormone given during IVF can improve the chance of getting embryos with the “right” number of chromosomes, which is checked by PGT-A. It may help some people who are 38 or older planning chromosome testing of embryos.
Shanghai, Shanghai MunicipalityAges 38 years+ - NCT07110285Recruiting
AI vs. doctor decision for IVF trigger day
This trial compares an artificial intelligence (AI) algorithm to doctors to decide the best day to give the trigger shot during IVF. It aims to see if AI can improve the number of mature eggs retrieved.
HerzliyaAges 18–45 - NCT06613100RecruitingPhase 1
Xaluritamig before prostate surgery for high-risk prostate cancer
This study tests an experimental drug called xaluritamig given before surgery for men with localized prostate cancer that is intermediate or high risk. The goal is to see if it can help shrink the cancer before the prostate is removed.
San Francisco, CaliforniaAges 18 years+ - NCT06379113RecruitingPhase 2/Phase 3
Hormone therapy for obesity-linked endometrial cancer that didn't respond to progestin
This trial tests a combination of two hormone-blocking drugs (GnRHa plus letrozole) for women with early-stage, obesity-related endometrial cancer who haven't responded well to standard hormone therapy alone. The goal is to preserve the uterus and fertility while controlling the cancer.
Shanghai, Shanghai MunicipalityAges 18–45 - NCT07171970Recruiting
IVM vs IVF for women with PCOS
This trial compares two fertility treatments for women with PCOS: in vitro maturation (IVM) with fresh embryo transfer versus standard IVF with frozen embryo transfer. It aims to find which approach leads to better outcomes.
Ho Chi Minh CityAges 18–42 - NCT07173127Recruiting
Ryeqo for fibroids and endometriosis: blood clotting study
This study looks at how Ryeqo, a medicine for uterine fibroids and endometriosis, affects blood clotting in women taking it. It aims to make sure the treatment is safe for your body's clotting system.

What GnRH antagonist is being studied for
Conditions with recruiting GnRH antagonist studies.
Common questions
- Are there clinical trials studying GnRH antagonist?
- Yes. Clin2 currently lists 14 recruiting studies that include GnRH antagonist, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a GnRH antagonist trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is GnRH antagonist an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether GnRH antagonist or a specific trial is right for you.
