About this study

A recent study by Plenge et al. revealed that rhEpo treatment enhances skeletal muscle mitochondrial respiratory capacity in humans indicating a muscle ergogenic effect of rhEpo on aerobic metabolism. The main purpose of the present study is to determine if a shorter treatment period with micro-dose as well as low-dose rhEpo has similar effects on muscle mitochondrial function.

Higher doses of rhEpo is known to increase cognitive performance, but it is not clear if lower doses of rhEpo have similar effects. A second purpose of the present study is to determine if micro-dose as well as low-dose rhEpo increases cognitive performance.

Read the detailed description

Twenty-five healthy young male volunteers are randomized to either a low-dose rhEpo (60 IU/kg/week), micro-dose rhEpo (20 IU/kg/week), or placebo control (saline) group. All subjects receive two subcutaneous injections per week for four weeks. Muscle biopsies are taken at the beginning and end of the study period. Mitochondrial function is measured in permeabilized fibres using high-resolution respirometry with the substrates malate (2mM), octanoyl carnitine (1.5mM), glutamate (10mM), succinate (10mM), under saturating [ADP] (5mM), and with the membrane uncoupler FCCP (1μM).

On the first day before administration of rhEpo and after the four weeks' treatment the subjects are undergoing two cognitive performance-tests, Raven Standard Progressive Matrices (Raven), and Number Finder (NUFI). Weekly semi-structured interviews are conducted by a blinded interviewer focusing on experienced change in cognitive performance.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Low-dose rhEpo and Micro-dose rhEpo in people with Human Volunteers, run by Bispebjerg Hospital at 1 site in Denmark.

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 4 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 28 Mar 2017. 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 Denmark. 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. Some participants in this study may receive a placebo. 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?

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?

Maximal oxygen-flux (picomol/second) (time frame: Four weeks). 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 NCT03093506, which also lists 2 linked publications.

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 28 Mar 2017.
