About this study

This is a single-centre, non-randomised, prospective study to assess the safety of the MediSieve blood filtration system in healthy volunteers

Read the detailed description

The MediSieve Magnetic Haemofiltration System (MMHS) is a system to filter selected moieties from blood in an extracorporeal circuit by magnetic means. Initially, it is developed for the treatment of severe malaria to capture malaria-infected erythrocytes (who are weakly magnetic) to reduce the parasitaemia. However, the use of MMHS can be extended, with the use of antibodies coupled to magnetic beads, to other diseases, such as sepsis.

The MMHS has to be used first in healthy volunteers to determine its clinical safety.

To this end, 6 healthy male and female volunteers (ratio 1:1) will undergo blood filtration using the MediSieve Magnetic Haemofiltration System (without magnetic beads) for five consecutive hours. Vital signs will be continuously monitored and blood samples will be obtained serially to determine laboratory safety and immunological parameters. Furthermore, volunteers will have two follow up visits at 24 hours and 7 days post filtration.

What participants receive

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

  • MediSieve Magnetic Haemofiltration SystemDevice

    The MediSieve Magnetic Haemofiltration System is a medical device intended for use in extracorporeal clinical procedures to remove magnetic targets (e.g. malaria infected red blood cells) from a patient's bloodstream. Healthy volunteers will undergo filtration for 5 hours.

  4. Safety (Symptoms)

    Clinical symptoms will be scored on a Likert scale (ranging from 0 to 5) in a composite endpoint consisting of headache, nausea, shivering, muscle soreness and lower back pain. Higher numbers indicate more severe symptoms.

    Measured: Samples will be obtained from 1 hour prior until 7 days after start of haemofiltration.

  6. Safety (Metal analysis)

    Plasma concentration levels of chromium and manganese will be measured in nmol/L.

    Measured: Samples will be obtained from start of haemofiltration, and after 1 hour, 5 hours, 24 hours and 7 days.

  7. Safety (Cell counts)

    Leukocytes (including differentation), erythrocytes and thrombocytes will be measured in *10^9/L.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  8. Safety (Haemoglobin and elektrolytes)

    Haemoglobin, sodium, potassium, calcium, phosphate, magnesium, and urea will be measured in mmol/L

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  9. Safety (Haematocrit)

    Haematocrit will be measured in L/L.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  10. Safety (Coagulation)

    Prothrombin time (PT), activated clotting time (ACT) and activated partial thromboplastin time (APTT) will be measured in seconds.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  11. Safety (INR)

    International Normalized Ratio (INR) will be measured to assess coagulation.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  12. Safety (Fibrinogen + albumin)

    Fibrinogen and albumin will be measured in grams/L.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  13. Safety (Kidney function)

    Kidney function will be measured in mL/min/1.73m^2.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  14. Safety (Markers associated with cellular damage)

    Cellular damage will be assessed by measuring Alanine Aminotransferase (ALAT), Aspartate Aminotransferase (ASAT), Lactate Dehydrogenase (LDH), Creatine kinase (CK), Alkaline phosphatase (AP)

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  15. Safety (C-reactive protein)

    C-reactive protein (CRP) will be measured in mg/L.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

  16. Safety (Creatinine and iron status)

    Creatinine, iron and total iron binding capacity (TIBC) will be measured in umol/L.

    Measured: Samples will be obtained from 2 hours prior until 7 days after start of haemofiltration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MediSieve Magnetic Haemofiltration System in people with Haemofiltration, run by MediSieve Limited at 1 site in Netherlands.

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 28 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 Feb 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 Netherlands. 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?

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?

Safety (Adverse events) (time frame: Continuously starting from 2 hours prior of the start of haemofiltration until 7 days post-filtration). 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 Feb 2023.
