About this study

Official title: Letrozole-metformin Versus Letrozole-metformin-pioglitazone in PCO Clomiphene Citrate Resistant Women

Polycystic ovary syndrome (PCOS) affects 5-10% of women in childbearing age. Hyperinsulinemia contributes to chronic anovulation commonly encountered in women with PCOS. The first choice therapy is clomiphene citrate (CC). In CC resistant cases, the American College of Obstetrics and Gynecology (ACOG) recommends the use of insulin sensitizer metformin. Other insulin sensitizing agents include rosiglitazone and pioglitazone. Pioglitazone is said to improve fertility and ovulation in patients with PCOS.CC may be associated with poor endometrial thickening due to its antiestrogenic effect. Letrozole may improve this condition. In this study we will compare the effect of combined letrozole-metformin with that of combined letrozole-pioglitazone in ovulation induction in CC-resistant PCOS women

Read the detailed description

Polycystic ovary syndrome (PCOS) affects 5-10% of women in childbearing age. Hyperinsulinemia contributes to chronic anovulation commonly encountered in women with PCOS. The first choice therapy is clomiphene citrate (CC). In CC resistant cases, the ACOG recommends the use of insulin sensitizer metformin. Other insulin sensitizing agents include rosiglitazone and pioglitazone. Pioglitazone is said to improve fertility and ovulation in patients with PCOS. CC has a long half-life (2 weeks), and this may have a negative effect on the cervical mucus and endometrium, leading to discrepancy between ovulation and conception rates. There has been a search for a compound capable of inducing ovulation but devoid of the adverse antiestrogenic effects of CC. recent studies have suggested that letrozole, an aromatase inhibitor, does not possess the adverse antiestrogenic effects of CC and is associated with higher pregnancy rates than CC treatment in patients with PCOS.

In this study the investigators shall compare the effect of combined letrozole-metformin with that of combined letrozole-metformin-pioglitazone in ovulation induction in CC-resistant PCOS women.This will be a prospective comparative clinical trial in which 2 groups of women will be generated (groups A and B) using the sealed envelopes randomization method.Group A (50 women) will receive: letrozole 2.5 mg/day from 3rd day of the cycle for 5 days and (pioglitazone 15 mg + metformin 850 mg) once daily from 1st day of the cycle for 10 days. Group B (50 women) will receive letrozole 2.5 mg/day from 3rd day of the cycle for 5 days and metformin 500 mg three times daily from continuously untill pregncy occurrs. Ovulation will be monitored by vaginal ultrasound and serum estrogen and progesterone.

What participants receive

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

  • letrozole-metforminDrug

    Also called femara-cidophage

    letrozole 2.5 mg will be given daily from day 3 of the cycle for 5 days + metformin 500 mg three times daily continuously for 3 months unless pregnancy occurred

  • letrozole-metformin-pioglitazoneDrug

    Also called femara- bioglita plus

    letrozole will be given daily from day 3 of the cycle for 5 days + (metformin 850 mg + pioglitazone 15 mg) from the first day of the cycle for 10 days.

  • transvaginal ultrasoundRadiation

    transvaginal ultrasound will be done from day 10 of the cycle and every other day for monitoring of follicular enlargement.

  • laboratory investigationsOther

    day 3: FSH, LH, TSH, and total testosterone day 12 serum E2 day 21 serum progesterone

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing letrozole-metformin, letrozole-metformin-pioglitazone and transvaginal ultrasound in people with Polycystic Ovary Syndrome and Infertility, run by Cairo University at 1 site in Egypt.

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 4 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 28 Jul 2015. 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 Egypt. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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?

ovulation rate (time frame: 6 months). 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 28 Jul 2015.
