About this study

Official title: Investigating the Mechanisms of Epigenetic Memory at the Example of the Responsiveness of Human Immune Cells to Vitamin D

The investigators will study the mechanistic details of dietary programming of the epigenome at the example of epigenetic programming of primary human immune cells with the micronutrient vitamin D3. They will follow a small number of healthy adult volunteers individually over time while measuring per individual a large number of molecular and dynamic parameters that will be used for mechanistic modeling. The main hypothesis of the investigators is that nutritional components, such as vitamin D3, have a direct effect on the epigenome of the different cell types of the immune system. Using complementary in vivo, in vitro and in silico approaches, they will investigate the mechanistic basis of this dietary epigenetic programming process and how it creates memory.

Read the detailed description

Exposure to dietary molecules during adulthood creates an epigenetic memory in immune cells affecting disease risk in later years of life. Many nutritional molecules have a direct effect on the human genome and/or epigenome, since they (or their metabolites) activate transcription factors or chromatin modifiers. This process is the mechanistic basis of the discipline nutrigenomics. Thus, the daily diet of humans leads to changes in the transcriptome and epigenome of many tissues and cell types. In this way, many physiological functions of the human body, such as a well-responding immune system, are influenced by diet. Some of these effects are not only transient but may lead to persistent changes of the epigenome in many different tissues. However, the mechanistic details of this dietary programming of the epigenome are not well understood. Therefore, in this study, the investigators will study this process at the example of epigenetic programming of primary human immune cells with the micronutrient vitamin D3. They will use the approach to follow a small but sufficient number of healthy adult volunteers (based on power calculation of self-controlled longitudinal studies) individually over time while measuring per individual a large number of molecular and dynamic parameters that will be used for mechanistic modeling, instead of investigating only few parameters from a large number of participants for statistical modeling. The main hypothesis of the investigators is that nutritional components, such as vitamin D3, have a direct effect on the epigenome of the different cell types of the immune system. Using complementary in vivo, in vitro and in silico approaches, they will investigate the mechanistic basis of this dietary epigenetic programming process and how it creates memory.

What is being measured

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

  1. Vitamin D-induced changes in the epigenome of PBMCs describing the individual -specific vitamin D response index of the study participants

    A bolus of vitamin D3 (monthly dose, taken once a month in three repeats) will change the epigenome (and transcriptome) of PBMCs of the study participants in an individual-specific way. These measurements will allow to distinguish the molecular response of the study participants, in order to segregate them into high, mid and low responders to vitamin D. This classification will lead to individual-specific recommendations for daily vitamin D3 supplementation in following winters. Moreover, the molecular investigations will allow a better understanding of the molecular mechanisms of vitamin D responsiveness

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vitamin D3 in people with Immune System Diseases and Infections, run by Polish Academy of Sciences at 1 site in Poland.

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 1 inclusion and 3 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 27 Oct 2023. 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 Poland. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 Carsten Carlberg, PhD (+48-89-523-4612, c.carlberg@pan.olsztyn.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Vitamin D-induced changes in the epigenome of PBMCs describing the individual -specific vitamin D response index of the study participants (time frame: 3 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 27 Oct 2023.
