Study summary

The primary objective of this multicenter observational registry is to characterize the clinical, epidemiological, and biological profiles of individuals of Middle Eastern, North African, and Levantine ancestry, including individuals with chronic medical conditions and healthy volunteers. The registry will collect standardized clinical and participant-reported data, along with biological samples, to support the investigation of disease patterns, health-related characteristics, and population-specific biological and immunological profiles in populations historically underrepresented in biomedical research. The resulting data and samples may support future research into disease-associated biomarkers and underlying biological mechanisms.

Read the detailed description

This is a multicenter, multi-purpose, observational registry designed to characterize the clinical, epidemiological, and biological profiles of individuals of Middle Eastern, North African, and Levantine ancestry. The registry will include individuals with chronic medical conditions as well as healthy volunteers.

The registry will collect standardized clinical information, medical history, relevant participant-reported information, and biological samples to support a broad range of current and future research investigating health-related characteristics, disease patterns, and biological variation in populations historically underrepresented in biomedical research.

Participants with chronic medical conditions may include individuals with, but are not limited to, the following conditions:

  • Cardiovascular diseases
  • Metabolic conditions, including hyperlipidemia and type 2 diabetes mellitus
  • Autoimmune diseases
  • Chronic gastrointestinal diseases
  • Dermatologic diseases, including atopic dermatitis and psoriasis
  • Respiratory diseases, including asthma and chronic obstructive pulmonary disease
  • Renal and urological disorders
  • Cognitive and neurological disorders
  • Other chronic medical conditions meeting the study's eligibility criteria Healthy volunteers may also participate.

Study procedures will include informed consent, eligibility assessment, collection of medical history and relevant clinical information, review of medical records where applicable, and collection of biological samples, as specified in the study protocol. Samples may include serum, plasma, peripheral blood mononuclear cells (PBMCs), and urine. The types of samples collected may vary among participants and participating sites.

This is an observational registry with no randomization. No investigational interventions or investigator-assigned treatments will be administered as part of the study. Participants' routine clinical care and treatment decisions will not be directed or modified by the registry.

The data and samples collected through the registry may support multiple future research projects addressing different scientific hypotheses across clinical, biological, and immunological domains. Research activities may include the investigation of disease-associated biomarkers and molecular or cellular characteristics, subject to participant consent.

Study population

Individuals of Middle Eastern, North African, or Levantine ancestry, including both participants with chronic conditions and healthy volunteers.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Individuals of Middle Eastern, North African, or Levantine ancestry, as determined by participant self-report.
  • Individuals aged 18 years or older with chronic medical conditions; a confirmed diagnosis or self-reported history of one or more chronic medical conditions, supported by medical record review where available.
  • Individuals below 18 years of age with a relevant chronic condition, where pediatric enrollment is subject to applicable ethical approvals and the required parental or legally authorized representative permission and participant assent, as applicable.
  • Healthy volunteers: Individuals aged 18 years or older without known chronic medical conditions relevant to the registry, based on participant self-report and investigator assessment.
  • Willing and able to provide written informed consent before initiation of any study procedures or, for pediatric participants, participation will be subject to applicable written parental/legal guardian permission and assent procedures, as appropriate.
  • Eligible and willing to undergo the applicable study procedures, including collection of relevant clinical information and biological samples.

Exclusion criteria

Exclusion Criteria:

  • Inability to obtain the required informed consent, parental or legally authorized representative permission, or participant assent, as applicable.
  • Acute illness, including fever (≥38°C), active infection, or a clinically unstable condition at the time of enrollment that, in the opinion of the investigator, may compromise participant safety or interfere with study procedures. Enrollment may be deferred until the condition resolves or the participant is clinically stable.

What researchers measure

Primary outcomes

  1. Distribution of Enrolled Participants by Clinical Condition

    Number and percentage of enrolled participants with each eligible chronic medical condition, including disease subtype where applicable. Healthy volunteers will be summarized separately from participants with chronic medical conditions.

    Time frame: At the enrollment/sample collection visit

Other outcomes

  1. Demographic and Anthropometric Characteristics of the Enrolled Population

    Demographic and anthropometric characteristics of enrolled participants, including age (years), sex, race/ethnicity, self-reported Middle Eastern and North African (MENA)/Levant ancestry, smoking status, body weight (kilograms), and height (centimeters). Categorical variables will be summarized using counts and percentages. Age, weight, and height will be summarized using appropriate descriptive statistics.

    Time frame: At the enrollment/sample collection visit

  2. Geographic Distribution of the Enrolled Population

    Geographic distribution of enrolled participants by the country or region recorded at enrollment. Findings will be summarized using counts and percentages, as appropriate.

    Time frame: At the enrollment/sample collection visit

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
