NCT05735886

Brief Summary

To show that a natural mitophagy activator (Urolithin A) given orally can modulate mitochondrial activity in immune cells in healthy adults and this results in better immune function

Outcome Measures

Primary Outcomes (2)

  • Change in percentages of CD3+ T-cell immune cell population

    In particular, number of CD8+ T memory stem cells (identified by expression of CD8+CD45RA+CCR7+CD95+) and naïve-like T cells (CD8+CD45RA+CCR7+CD95-)

    28 days

  • Change in Mitochondrial activity in CD3+ T-cells

    Mitochondrial function evaluated as OXPHOS activity via ELISA /Seahorse

    28 days

Secondary Outcomes (8)

  • Change in pro and anti-inflammatory cytokine levels (IL-6, TNF-a, IL1-B, IL-10) in plasma and/or ex-vivo antigenic stimulation

    28 days

  • Change in percentages of other immune cell populations (B cells, NK cells, Macrophages, DCs etc.) via flow cytometry

    28 days

  • Change in Mitochondrial content on CD3 T-cell populations via Mitotracker staining using flow cytometry

    28 days

  • Change in gene-expression: single cell analysis of CD3+ T-cells

    28 days

  • Change in PBMC's immune function assessment (mixed-leukocyte reaction (MLR) via antigenic stimulation

    28 days

  • +3 more secondary outcomes

Eligibility Criteria

Age45 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy Adults that do not suffer from an uncontrolled chronic medical condition that carries metabolic consequences (as assessed by the study physician)
  • BMI\<35kg/m2
  • Provide informed consent
  • Adults aged 45-70 years, both genders
  • Subjects who have not received any systemic immunosuppression in the past 6 months
  • Subjects with any medical condition that in the opinion of the investigators would compromise the study outcome or the safety of the research participant

You may not qualify if:

  • Subject has any concurrent medical, orthopedic, or psychiatric condition that, in the opinion of the Investigator, would compromise his/her ability to comply with the study requirements;
  • Clinically significant abnormal laboratory results at screening
  • Participation in a clinical research trial within 30 days prior to randomization
  • Allergy or sensitivity to study ingredients
  • Individuals who are cognitively impaired and/or who are unable to give informed consent
  • Any condition which in the Investigator's opinion may adversely affect the subject's ability to complete the study or its measures or which may pose significant risk to the subject
  • Current gastrointestinal condition which could interfere with the study (e.g. IBS/IBD, diarrhea, acid reflux disease, dysphagia etc.);
  • Excessive alcohol consumption and/or a smoker
  • Concomitant use of statins
  • Engage in regular moderate or vigorous physically activities (i.e. Category 3 as per the IPAQ activity classification)
  • Concomitant use of corticosteroids, antibiotics, any anabolic steroid, creatine, whey protein supplements, casein or branched-chain amino acids (BCAAs), immune-boosting(Vitamin C, Zinc) or mitochondrial (COQ10, NAD+) supplements within 45 days prior to screening
