About this study
In the ADDITION-MCI project, patients with a diagnosis of mild cognitive impairment probably caused by Alzheimer's disease will receive plasma exchange.
Read the detailed description
Repeated plasma exchanges will be conducted, and cognitive outcomes will be measured before and after the intervention.
- Conditions
- Alzheimer Disease
- Being tested
- Plasma exchenge
- Medical subject headings
- Alzheimer Disease
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Plasma exchengeBiological
Plasma exchange will be conducted. The substitution fluid will be plasma from ha healthy donor.
| Study group | Role | What they receive |
|---|---|---|
| Plasma exchange | Experimental | 1-20 plasma exchanges. Receives: Biological: Plasma exchenge |
What is being measured
The primary outcome is the main question the study is designed to answer.
Adverse events
Safety of the intervention in the patient group measured as number and severity of adverse events.
This will be evaluated as the number of participants with treatment-related adverse events as assessed by CTCAE v5.0.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Plasma exchenge in people with Alzheimer Disease, run by Oslo University Hospital at 1 site in Norway.
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 5 inclusion and 14 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 31 Jan 2024. 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 Norway. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
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?
Adverse events (time frame: Up to 4 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06234436, which also lists 1 linked publication.
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 31 Jan 2024.
