Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 23 to 48 years
  • Women only
  • No healthy volunteers
  • Adult

Who may be able to join

  • Women aged above 23 years with diminished ovarian reserve (predicted to be poor-responder), defined as antral follicle count <10 and/or Anti-Mullerian hormone <5pmol/L
  • Women undergoing IVF and IVF/ICSI treatment
  • Women must have a regular spontaneous menstrual cycle of 21 - 35 days

Who cannot join

  • Women with BMI >35 Kg/M2
  • Women with a single ovary
  • Women with untreated hydrosalpinx/ submucous fibroid/ endometrial polyp at the start of treatment
  • Women with any history of seizure disorders
  • Women with previous participation in this trial in an earlier treatment cycle
  • Women with any known endocrine disorders such as congenital adrenal hyperplasia, thyroid diseases, hyperprolactinemia
  • Known allergy to DHEA
  • Diabetic women on insulin as insulin lowers DHEA levels and might reduce the effectiveness of DHEA supplements.

About this study

Official title: Efficacy of Dehydroepiandrosterone to Overcome the Effect of Ovarian Aging - A Pilot Double Blinded Randomised Controlled Trial

  • To test the hypothesis that supplementation of DHEA for at least twelve weeks prior to and during ovarian stimulation increases oocyte quantity (number of oocytes retrieved) and oocyte quality (clinical pregnancy rates and molecular markers) following IVF and IVF/ICSI treatment.
  • To evaluate the feasibility of conducting a large multicentre trial
Read the detailed description

The purpose of this study is to evaluate the role of DHEA in counteracting the effects of ovarian ageing in an in-vitro fertilization (IVF) model. The study will examine whether the use of DHEA could improve clinical pregnancy rates following IVF treatment in women predicted to have aged ovaries by increasing oocyte quantity (ovarian response to gonadotrophins) and/ or by improving oocyte quality. The oocyte quality will be assessed by morphological and molecular markers.

This study will provide a mechanistic framework for translational research on mechanisms of ovarian ageing and drug interventions to slow down the ovarian ageing process and subsequent adverse physical and psychological consequences. Further, the data that will be produced from this research will have the potential to influence clinical practice in fertility clinics worldwide.

What participants receive

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

  • DehydroepiandrosteroneDrug

    Dehydroepiandrosterone (DHEA)(St Mary's Pharmaceutical Unit Cardiff and Vale) DHEA 75 mg capsule. 1 capsule taken once daily for at least 12 weeks prior commencing ovarian stimulation protocol

    : Stimulation protocol standard long down-regulation protocol, using human menopausal gonadotropin (HMG)

  • PlaceboDrug

    Matched Placebo containing no active ingredient. 1 capsule taken once daily for at least 12 weeks prior commencing ovarian stimulation protocol

    : Stimulation protocol standard long down-regulation protocol, using human menopausal gonadotropin (HMG)

What is being measured

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

  1. Number of oocytes retrieved

    Oocytes retrieved within 15 weeks after DHEA/placebo supplementations.

    Measured: within 15 weeks after DHEA/Placebo supplementation

  2. Feasibility to conduct a large multicentre randomised controlled trial

    Feasibility is evaluated by assessing recruitment rates and compliance of the recruited participants with DHEA/ placebo intake and follow up rates

    Measured: with in 20 weeks of the research period (per participant)

Secondary outcomes (2)
  1. Oocyte quality (clinical and molecular markers)

    Clinical pregnancy rates (Pregnancy rate determined at week 5 to 7 after embryo transfer).

    Molecular markers of oocyte quality as assessed by expression of cumulus cell molecular markers of oocyte competence and also by assessing energy consumption (pyruvate, lactate and glucose utilization) from the media by the oocytes and embryos (nutritional finger printing)

    Measured: The sample is collected at 14-16 weeks after recruitment and assessment is performed at one year.

  2. Aneuploidy rates in the immature oocytes and unfertilized oocytes using microarray technology

    Measured: The sample is collected at 14-16 weeks after recruitment and assessment is performed at one year.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dehydroepiandrosterone in people with Infertility and Ovarian Aging, run by University of Nottingham at 1 site in United Kingdom.

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 3 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: finished, as of the sponsor's last update on 9 Dec 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 United Kingdom. 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. Some participants in this study may receive a placebo. 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 oocytes retrieved (time frame: within 15 weeks after DHEA/Placebo supplementation). The study lists 2 primary outcomes in all. 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 NCT01572025, 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 9 Dec 2015.
