Myo-inositol for the Management of Poor Ovarian Responders: A Prospective Randomized Controlled Trial
A Phase 2/3 study testing Myo-inositol in people with Poor Ovarian Response, run by American University of Beirut Medical Center at 1 site in Lebanon.
Trial summary
The management of poor ovarian responders (POR) remains the most challenging in In-Vitro Fertilization (IVF). The incidence of POR ranges between 9 and 24% (Caprio F, et al, 2015). POR refers to a reduction in the quantity of primordial follicle pool in reproductive age group (Jirge, P. R., 2016, Sunkara, S. Read more about this study

About this study
The management of poor ovarian responders (POR) remains the most challenging in In-Vitro Fertilization (IVF). The incidence of POR ranges between 9 and 24% (Caprio F, et al, 2015).
POR refers to a reduction in the quantity of primordial follicle pool in reproductive age group (Jirge, P. R., 2016, Sunkara, S. K., et al, 2014), in addition to a higher risk of implantation failure (Kailasam C, et al, 2004).
To overcome this condition, fertility treatments using controlled ovarian stimulation along with IVF is needed to achieve pregnancy. Despite the use of various treatments including high dose gonadotropins, patients with POR have lower rates of pregnancy compared to patients with normal ovarian response (Oudendijk, J. F., et al, 2011). Studies now suggest a variety of regimens like the use of growth hormones, DHEA or androgens to improve the outcomes (Kyrou D, et al, 2009). The main interest of this study is the use of myo-inositol prior to IVF cycles for improvement of reproductive outcomes in poor ovarian responders.

The management of poor ovarian responders (POR) remains the most challenging in In-Vitro Fertilization (IVF). The incidence of POR ranges between 9 and 24% (Caprio F, et al, 2015).
POR refers to a reduction in the quantity of primordial follicle pool in reproductive age group (Jirge, P. R., 2016, Sunkara, S. K., et al, 2014), in addition to a higher risk of implantation failure (Kailasam C, et al, 2004).
To overcome this condition, adjuvant fertility treatments using controlled ovarian stimulation along with IVF is needed to achieve pregnancy. Despite the use of various treatments including high dose gonadotropins, patients with POR have lower rates of pregnancy compared to patients with normal ovarian response (Oudendijk, J. F., et al, 2011). Studies now suggest a variety of regimens like the use of growth hormones, DHEA or androgens to improve the outcomes (Kyrou D, et al, 2009).
Inositol belongs to the vitamin B group, precursor for the synthesis of phosphatidylinositol polyphosphates (PIPs). PIPs belong to the signal transduction system involved in the regulation of different cellular functions such as signal transduction, cell morphogenesis and cytogenesis (Kutateladze TG, 2010). It is involved in cell membrane formation, lipid synthesis and cell growth (Unfer V, et al, 2012). It has been extensively studied in patients with insulin resistance, as inositol has an insulin sensitizing action (Croze ML \& Soulage CO, 2013). In addition, researchers have hypothesized different mechanisms of action on different cell types especially at the level of the ovaries. An international consensus has confirmed that myo-inositol pre-treatment is able to improve the oocyte and the embryo quality via enhancing the intracellular Ca2+ oscillation with meiotic progression of germinal vesicle oocytes. Therefore, it acts on improving the oocyte maturation and embryo development (Nestler JE, et al, 1999, Papaleo E, et al, 2009).
Previous studies showed that higher concentrations of myo-inositol in follicular fluid are correlated with a better oocyte quality (Chiu TT, et al, 2002). A study by Jiang demonstrated that inositol supplementation reduces oxidative stress by different agents such as increasing superoxide dismutase and catalase levels (Jiang WD, et al, 2011). In view of its effects on oocyte maturation and quality, the use of myo-inositol in women with POR is promising. However, data is still sparse whether supplementation with myo-inostiol prior to IVF cycles does improve the pregnancy outcomes.
The main interest of this study is the use of myo-inositol prior to IVF cycles for improvement of reproductive outcomes in poor ovarian responders.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Myo-inositol in people with Poor Ovarian Response, run by American University of Beirut Medical Center at 1 site in Lebanon.
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 5 inclusion and 2 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 18 Feb 2020. 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 Lebanon. 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Antoine Abu Mussa, MD (01350000 ext. 5445, aa06@aub.edu.lb), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Retrieved oocytes (time frame: 4 months). 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 NCT04273256, which also lists 12 linked publications.
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 18 Feb 2020.
