About this study
Official title: A Prospective Double-blind Randomized Trial Comparing Pregnancy Rates After Low Dose Human Chorionic Gonadotropin (hCG) at the Time of Gonadotropin Releasing Hormone (GnRH) Agonist Trigger or 35 Hours Later for the Prevention of OHSS
This a prospective randomized double blind study involving patients at high risk of OHSS development with peak serum E2 levels < 4,000 pg/ml comparing the ongoing pregnancy rates in patients who receive adjuvant hCG 1,000 IU at the time of GnRH agonist trigger or adjuvant hCG 1,500 IU 35 hours after GnRH agonist trigger.
Read the detailed description
Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of controlled ovarian hyperstimulation which may result in significant morbidity and rarely mortality as well as significant financial and psychological distress. GnRH agonist trigger has been shown to be effective in OHSS prevention. However, the adoption of its use has not been widely accepted in view of concerns regarding potential impairment of implantation.
Intensive luteal phase supplementation with estrogen (E2) and progesterone (P) is important due to the strong evidence of abnormal luteal phase serum E2 and P profiles. However, it has been shown that optimal conception rates is not achieved for high risk patients with peak serum E2 < 4,000 pg/ml despite aggressive steroidal supplementation. It has been proposed that the use of adjuvant low dose hCG at the time of GnRH agonist trigger or 35 hours later will rescue some of the corpora lutea and help improve corpora lutea function and improve pregnancy rates.
The study will evaluate patients at high risk of OHSS development with peak serum E2 < 4,000 pg/mL to determine whether timing of low dose hCG administration affects ongoing pregnancy rates or risk of OHSS. Markers of corpus luteum function such as serum 17 hydroxy-progesterone and prorenin during the luteal phase and early pregnancy will help elucidate further the effect of adjuvant low dose hCG with GnRH agonist trigger on corpus luteum function.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing hCG in people with Ovarian Hyperstimulation Syndrome, run by UConn Health at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 25 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Ongoing Pregnancy (time frame: Through time of study completion, on average 1-2years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01815138, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2018; AzTrials last refreshed its copy on 7 Nov 2026.
