Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 40 to 60 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Study population: 41 donors are welcomed to begin with the study. The participants are divided into 2 groups (Group 1 = therapeutic, Group 2 = half control) using stratified randomization, major criteria being chronological age and BMI, minor criteria being illness/medication, smoking, COVID in past 3 months, covid vaccination. Group 1 consists of 28 participants (14 female, 14 male). Group 2 consists of 13 participants (7 female, 6 male). We suppose that the number of participants will decline during each phase of the study, approx. 10% before it even starts, 10% in the middle, 10% in the end. The goal is to have more than 30 participants finishing the study.

Who may be able to join

  • Generally healthy volunteer subjects age 40 - 60
  • 50:50 man and woman

Who cannot join

  • Subjects excluded from plasma donation protocols (serious illness, infection, etc)
  • Subjects undergoing stronger anti-aging interventions

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PlasmapheresisProcedure or surgery

    Procedure whereby plasma is separated and extracted from anticoagulated whole blood and the red cells retransfused to the donor.

Study groups in NCT05004220
Study groupRoleWhat they receive
Group 1Group 1 consists of first time donors undergoing all 8 tracked plasmaphereses.
Receives: Procedure: Plasmapheresis
Group 2Group 2 consists of first time donors undergoing only last 4 plasmaphereses, serving as control for the first 4 donations.
Receives: Procedure: Plasmapheresis

What is being measured

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

  1. Significant change of biological age according to epigenetic clock after 8 plasmaphereses

    Significant change of the epigenetic age of the plasma donors after 8 cycles of plasmapheresis conducted or a slower increase of the biological age throughout the study than the increase of the chronological age.

    Measured: Through study completion, an average of 8 months

Secondary outcomes (5)
  1. Significant change of biological age according to epigenetic clock after 8 plasmaphereses

    Significant change of the epigenetic age of the plasma donors after 4 cycles of plasmapheresis conducted or a slower increase of the biological age throughout the study than the increase of the chronological age.

    Measured: Through study completion, an average of 8 months

  2. Significant change of the proteomic profile after 8 plasmaphereses

    Proteomic analysis showing signs of a rejuvenated proteostasis in the plasma donors after 8 cycles of plasmapheresis.

    Measured: Through study completion, an average of 8 months

  3. Significant change of the proteomic profile after 4 plasmaphereses

    Proteomic analysis showing signs of a rejuvenated proteostasis in the plasma donors after 8 cycles of plasmapheresis.

    Measured: Through study completion, an average of 8 months

  4. Significant change of the biological age according to a blood biochemistry clock after 8 plasmaphereses

    Blood biochemistry clock showing phenotype of a younger individual in the plasma donors after 8 cycles of plasmapheresis.

    Measured: Through study completion, an average of 8 months

  5. Significant change of the biological age according to a blood biochemistry clock after 4 plasmaphereses

    Blood biochemistry clock showing phenotype of a younger individual in the plasma donors after 8 cycles of plasmapheresis.

    Measured: Through study completion, an average of 8 months

Questions about this trial

What is this clinical trial studying?

An observational study of Aging and Plasmapheresis, run by Charles University, Czech Republic at 1 site in Czechia.

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 2 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: finished, as of the sponsor's last update on 6 Sep 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 Czechia. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Significant change of biological age according to epigenetic clock after 8 plasmaphereses (time frame: Through study completion, an average of 8 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 6 Sep 2023.
