About this study

Official title: Supplementation of Zinc-AA Complexes in Women During Pregnancy and Lactation, to Assess Effects on Autism Spectrum Disorder (ASD), Immune Status and Gut Microbiota in Offspring

Autism and associated entities, grouped under the Autism Spectrum Disorders (ASD) is the fastest growing intellectual disability in the world, statistics signal for a 1 to 3% prevalence on infants. The cause is unknown, although some data suggest that zinc deficiency during pregnancy may have an important role in its presentation. This study seeks to supplement the nutrition of randomly selected prospective and actually pregnant women with a zinc-Amino-acid complex (Zn-AA), during pregnancy and early lactation, and compare the rate of ASD in their offspring with the rate in a similar and also randomly selected cohort of non supplemented women, to assess if Zn-AA supplementation during pregnancy has any effect on this outcome

Read the detailed description

Autism and associated disorders (Autism Spectrum Disorders, ASD) is the fastest growing disability in the world, statistics indicate a prevalence of between 1 and 3%. This entity is the one that generates more stress in families, four times more than in a neuro-typical family and twice more than in a family with any other disability. Besides, this condition increases health spending for the family, the state and the country.

By not knowing the cause, and witnessing the growth of this disability, with the prevalence described, and the births reported in 2019 in Mexico (2,092,214), we expect between 20,922 and 62,766 new cases in our country each year. In Nuevo León, a state in the northeast of Mexico, the average birth rate per year from 2017 to 2019 (latest official data available) is 91,484, which makes us estimate an incidence of 915 to 2744, for the same period. ASD is also a family stressful disability, associated to a high rate of separations, social isolation and divorces, which leads to social problems of alarming dimensions. In the United States, for 2025 the cost of Autism is projected at 1 trillion dollars, associated with medications, interventions and educational expenses.

In Mexico, the lack of universal diagnostic screening, detection and intervention programs before the age of three years makes those affected to require important support throughout their lives, since the benefits of early intervention are lost.

This project consists of two parts. The first is the Primary Study. It consists of establishing whether the supplementation of Zinc-AA complexes, in women during pregnancy and lactation, has any effect on the prevalence of Autism and if it favorably modifies the immunological and metabolic status of the mother and the progeny; seeks to confirm the findings that our group of investigators has obtained in published pre-clinical investigations that found that a Zinc deficiency in the mother (mice and human erythrocytes), caused by dietary factors, provokes changes in the morphology of the intestine of the progeny, as well as modifications in the microbiota and increased inflammatory markers in the blood and brain, similar to those reported in people with Autism. In Latin America, the diet is based on cereals, and i so abundant in dietary fiber and phytates. These factors, along supplements usually recommended to mothers who plan to become pregnant (Calcium, Iron and Folic Acid), predispose these women to Zinc deficiency. We are also proposing a Secondary Study, to establish the zinc status and the characteristics of the intestinal microbiome in young, non-pregnant adult women, as a comparative reference standard.

Until now, there are no projects in the world that seek to partially or totally solve the causes of Autism, this is the first study that seeks to prevent the problems associated with autism and could be the first to influence the reduction of the incidence of Autism. This project will involve Mexican researchers from Instituto Tecnologico y de Estudios Superiores de Monterrey (ITESM), as well as researchers from the University of Limerick, Ireland, from the University Clinic of the Autonomous University of Nuevo León, in the northeast of Mexico; as well as the Laboratory of Dr. Fanis Missirlis, of the National Polytechnic Institute, in Mexico City.

This project has the financial support of the International Zinc Association (IZA), managed by Zinpro Corp., represented in Mexico by Elemend Salud, representative Ing. Guillermo Vela Staines (g.vela@zinpro.com).

What is being measured

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

  1. Autism spectrum disorder

    Positive identification of any component of the Autism Spectrum Disorder (ASD) through the Autism Diagnosis Observation Schedule, 2nd edition (ADOS-2) specialized battery of tests, which provide a standardized set of tests that offer as output a set of ranges of concern reflecting the extent to which a child demonstrates behaviors associated with ASD.

    Measured: From 16 to 20 months of age

Secondary outcomes (2)
  1. Microbiota modification associated to maternal zinc supplementation or placebo during pregnancy

    Comparative analysis of the microbiome composition (Type and relative quantity of micro-organisms) in a subset of the supplemented and the un-supplemented groups, at birth, and also at the end of the first six months of lactation

    Measured: From birth to six months of age

  2. Immune phenotype

    Comparison of the Immune phenotype (Type and quantity of main Interleukines and Cytokines in peripheral blood, and characterization of Leucocyte population and subpopulation, also in peripheral blood) in a subset of the supplemented and the un-supplemented groups, at birth, and also at the end of the first six months of lactation

    Measured: From birth to six months of age

Questions about this trial

What is this clinical trial studying?

A study testing Zn-AA in people with Autism Spectrum Disorder and Zinc Deficiency, run by Instituto Tecnologico y de Estudios Superiores de Monterey at 1 site in Mexico.

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 5 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: stopped early, as of the sponsor's last update on 6 Mar 2024. 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 Mexico. 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.

Are results available for this study?

The study was stopped early (reason given: A funding agreement could not be secured with the primary funding organizations). Results are not available in the source record.

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?

Autism spectrum disorder (time frame: From 16 to 20 months of age). 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 6 Mar 2024.
