Trial summary

To test whether GnRHa withheld 2-3 days before ovulation trigger reduces the incidence of ovarian hyperstimulation syndrome (OHSS) in infertile high-risk patients with polycystic ovaries (PCOs) who have been treated with gonadotropins for in vitro fertilization (IVF) or Intracytoplasmic sperm injection (ICSI).

About this study

Official title: Study of Effect of GnRHa Withdrawal at Late Stage of Long Protocol on the Risk of Ovarian Hyper-stimulation in Patients With Polycystic Ovary (PCO) Undergoing in Vitro Fertilization/Intracytoplasmic Sperm Injection Cycles

To test whether GnRHa withheld 2-3 days before ovulation trigger reduces the incidence of ovarian hyperstimulation syndrome (OHSS) in infertile high-risk patients with polycystic ovaries (PCOs) who have been treated with gonadotropins for in vitro fertilization (IVF) or Intracytoplasmic sperm injection (ICSI).

Read the detailed description

All the patients received a midluteal long GnRH agonist (GnRH-a) and a gonadotropins (recombinant FSH) stimulation protocol. Pituitary down-regulation with GnRH agonist (triptorelin, 0.1mg/d, ×10d, then 0.05mg/d until E2 ≤40 pg/ml in serum), was initiated during the luteal phase on the cycle-day 21. Two weeks later, if E2 in serum was ≤40 pg/ml and absence of follicular activity was detected, the stimulation of ovaries was started by recombinant follicle-stimulating hormone (recFSH, Gonal-F, Serono, Switzerland) with doses ranging 150-250 IU/d. Doses were adjusted accordingly with ovarian monitoring and follicles growth. GnRHa (0.05mg/d) was injected stimulously with FSH before dominant follicles were ≥ 14 mm. When the diameter of one or more follicles was ≥ 14 mm, GnRHa (0.05mg/d) was withheld in the study group. In the control group, GnRHa was used to the day of ovulation trigger. Ovulation was induced with HCG (5000-10000 IU) when at least three follicles greater than 16mm in diameter were detected on ultrasound examination and the leading follicles reached ≥ 18 mm in diameter. Oocytes retrieval for IVF or ICSI was performed 34-36 hours later under transvaginal ultrasound guidance.

Main Outcome Measure(s): Serum E2 levels, VEGF levels in Serum and follicular fluids, retrieved oocytes, fertilization, implantation rate and pregnancy rate (PR), the rate of OHSS.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. incidence of ovarian hyperstimulation

    Ovarian hyperstimulation syndrome is a complication from some forms of fertility medication. Most cases are mild, but a small proportion are severe. Symptoms are set into 3 categories: mild, moderate, and severe.

    Measured: two weeks

Secondary outcomes (1)
  1. pregnancy rate in the patients with IVF or ICSI

    Measured: one month

Questions about this trial

What is this clinical trial studying?

A study testing a drug withdrawal during the long protocol in people with Infertile High-risk Patients With Polycystic Ovaries, run by Nanjing University at 1 site in China.

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: status not confirmed, as of the sponsor's last update on 10 Jul 2012. 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 China. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Bin Wang, Master (86-25-8310-7170, wangbin_429@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

incidence of ovarian hyperstimulation (time frame: two weeks). 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 NCT01634724, which also lists 1 linked publication.

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 10 Jul 2012.
