About this study

Official title: Comparison of Two Types of Dual Ovarian Stimulation: Duostim Versus Shanghai Protocols in Patients With Poor Ovarian Reserve: A Randomized Controlled Trial

A combination of follicular phase stimulation and luteal phase stimulation in the same cycle, can be a valuable choice in poor responder patients with reduced ovarian reserve, in order to achieve extreme the number of oocytes in a single menstrual cycle. In the present study, the results of two different Double stimulation cycles including shanghai protocol and Duostim protocol in patients with reduced ovarian reserve, compared with each other to help select a more appropriate treatment for this group of patients. The number of retrieved oocytes and the number of obtained embryos and clinical pregnancy from each protocol will be compared as the primary and secondary outcome.

Read the detailed description

The proposal of this randomized clinical trial study is a comparison of two different type of double stimulation protocols in patients who meet the POSEIDON (Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number) stratification (group 4) criteria.

In mild double stimualtion (Shanghai protocol), patients will be received Clomiphene citrate 25 mg/day (Ovumid®; Iran Hormone pharmaceutical Co., Iran) co-treatment and letrozole 2.5 mg/day (Femati®, Atipharmed Co., Iran) will be given from cycle day 3. Letrozole is given for 4 days and clomiphene citrate is used daily before the trigger day. Patients take 150 IU of Human menopausal gonadotropin (HMG) (Humegnan®, Darou Pakhsh Co., Iran) every other day beginning on cycle day 6. When one dominant follicle will reach 18 mm, the final triggering will induce 34-36 h after 0.5 cc of Buserelin acetate (CinnaFact®; CinnaGen pharmaceutical Co., Iran) administration. In luteal phase stimulation a total of 225 IU HMG and letrozole 2.5 mg will administered daily from3 to 5 days after oocyte retrieval. Letrozole administration will be stopped when the dominant follicles reached 12 mm. When one dominant follicle will reach 18 mm, the final triggering will be induced with 0.5 cc of Buserelin acetate (CinnaFact®; CinnaGen pharmaceutical Co., Iran).

In the double GnRH- antagonist (Duostim protocol), both follicular and luteal phases stimulation will perform with 150-225 IU of recombinant FSH (Gonal-F®, Merck-sereno, Germany) and HMG (Humegnan, Darou Pakhsh Co., Iran) in GnRH antagonist treatment. The follicular stimulation will be started on day 2-3 of the menstrual. Daily administration of 0.25 mg of GnRH antagonist (Cetrotide®, Merck-Serono; Germany) will be started when the leading follicle are 13-14mm and continue until the day of the oocyte trigger. When one follicle reached 17-18 mm ovulation will be triggered with 0.5 cc of Buserelin acetate (CinnaFact®; CinnaGen pharmaceutical Co., Iran) and oocyte retrieval will be performed after 34-36 hours. Five days after the first oocyte retrieval, a GnRH antagonist protocol identical to the first one will start. When at least two follicles reached 17-18 mm, the ovulation will be triggered with a subcutaneous bolus GnRH-agonist and the second oocyte retrieval will be performed.

In all of groups all of embryos will be freeze and will be used in subsequent frozen embryo transfer (FET) cycles. Endometrial preparation for FET cycle will perform with hormonal replacement therapy (HRT) cycle protocol.

    Also called Double GnRH-antagonist stimulation

    In Duostim group, the follicular stimulation will be started with a fixed dose of 150 IU of rFSH and HMG 75 IU for 4 days. Daily administration of a GnRH antagonist will be started when the leading follicle are 13-14mm in diameter and continue until the day of the trigger of the ovulation. Five days after the first oocyte retrieval second gonadotropin stimulation will be started identical to the first one..

Five days after the first oocyte retrieval, a GnRH antagonist protocol identical to the first one will start. When at least two follicles reached 17-18 mm, the ovulation will be triggered with a subcutaneous bolus GnRH-agonist and the second oocyte retrieval will be performed.
Receives: Other: Doustim protocol
Double mild stimulation protocolNo interventionIn double mild stimulation protocol, Clomiphene citrate 25 mg/day (Ovumid®; Iran Hormone pharmaceutical Co., Iran) and co-treatment with letrozole 2.5 mg/day (Femati®, Atipharmed Co., Iran) will be given from cycle day 3. Letrozole is given for 4 days and clomiphene citrate is used daily before the trigger day. Patients take 150 IU of Human menopausal gonadotropin (HMG) (Humegnan®, Darou Pakhsh Co., Iran) every other day beginning on cycle day 6. When one dominant follicle will reach 18 mm, the final triggering will induce 34-36 h after 0.5 cc of Buserelin acetate (CinnaFact®; CinnaGen pharmaceutical Co., Iran) administration. In luteal phase stimulation a total of 225 IU HMG and letrozole 2.5 mg will administered daily from3 to 5 days after oocyte retrieval. Letrozole administration will be stopped when the dominant follicles reached 12 mm. When one dominant follicle will reach 18 mm, the final triggering will be induced with 0.5 cc of Buserelin acetate.

What is being measured

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

  1. Number of MII oocytes

    Oocytes that were mature at the time of oocyte collection (Metaphase II)

    Measured: Immediately after oocyte puncture

Secondary outcomes (5)
  1. Number of cleaved embryos

    2-3 days embryo from fertilization

    Measured: 2-3 days after oocyte puncture

  2. Number of blastocyst embryos

    The stage the embryo reaches after 5 days in culture from the oocyte retrieval

    Measured: 5 days after oocyte puncture and sperm insemination

  3. Clinical pregnancy rate

    The observation of gestational sac on ultrasound examination two-three weeks after positive serum βhCG

    Measured: 4-6 weeks after embryo transfer

  4. Fertilization rate

    Percentage of transformation of micro injected oocytes into two pronuclei

    Measured: 2-5 days after sperm insemination

  5. Quality of oocytes

    Oocyte quality were assessed by embryologist based on The Istanbul consensus workshop (Hum Reprod.2011). Quality of MII oocytes (based on intracytoplasmic and extracytoplasmic abnormalities) was divided into 3 groups; morph, slightly dysmorph, and dysmorph.

    Measured: Immediately after oocyte puncture

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of MII oocytes (time frame: Immediately after oocyte puncture). 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 10 Jan 2024.
