About this study

Official title: Randomized Prospective Controlled Non-inferiority Trial of Low-dose Clomiphene Based Antagonist Protocol vs. High Dose Gonadotropin/Antagonist Protocol for IVF Poor Responders

The purpose of this study is compare two commonly-used medication protocols ( low-dose clomiphene citrate and high dose gonadotropin protocols) for the treatment of patients with diminished ovarian reserve (decreased number of eggs remaining in the ovary) undergoing IVF. This research is being done because we do not know if these two medication protocols are equally likely to help a woman become pregnant.

Read the detailed description

The objective of this protocol is to prospectively evaluate whether a clomid-based, low dose gonadotropin protocol (225 IU) would be non-inferior in terms of mature oocyte yield (eggs that are ready to be fertilized) as compared to a high-dose protocol.

Patients meeting the criteria for poor ovarian response will be consented and randomized to either a stimulation protocol involving pretreatment with a 0.1mg estradiol patch in the luteal phase starting 10 days after the LH surge (the hormone released by the brain to cause ovulation to occur, which is detectable in urine) followed by oral clomiphene citrate 100mg on days 2-6 of the menstrual cycle and 225 international units of gonadotropins starting on day 5, or to the control group involving the same pretreatment with 0.1mg luteal estradiol patches starting 10 days after the LH surge, with high dose gonadotropins (600IU) alone, starting on day 2 of the cycle. After randomization, patients will undergo routine IVF procedures, monitoring, blood draws, cancellation criteria, oocyte retrieval, and embryo transfer as non-study participants.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Low-dose ClomipheneDrug

    Also called clomiphene citrate with low dose gonadotropins

    Pretreatment with a 0.1mg estradiol patch in the luteal phase starting 10 days after the LH surge followed by clomiphene citrate 100mgon days 2-6 of the menstrual cycle with 225 international units of gonadotropins (eg Follistim , Menopur) starting on day 5

  • High dose gonadotropinsDrug

    Also called Gonal F or Follistim

    Pretreatment with a 0.1mg estradiol patch in the luteal phase starting 10 days after the LH surge followed high dose gonadotropins (eg. Follistim. Menopur) 600IU starting on day 2 of the cycle

What is being measured

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

  1. The number of mature oocytes retrieved

    To evaluate the number of mature oocytes retrieved in two different IVF protocols for poor responders

    Measured: 1 year

Secondary outcomes (1)
  1. The number of embryos transferred

    To evaluate the number of embryos transferred

    Measured: 1year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Low-dose Clomiphene and High dose gonadotropins in people with Infertility, run by Weill Medical College of Cornell University.

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 2 inclusion and 8 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: withdrawn, as of the sponsor's last update on 16 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

The number of mature oocytes retrieved (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Dec 2016.
