About this study

Official title: A Dose-response Study of Markers of Glucocorticoid Effects (DOSCORT): A Double-blinded, Randomized, 2-dose, Cross-over Study

DOSCORT is a 2-dose, cross-over study primarily aiming to identify and validate novel biological markers (biomarkers) of glucocorticoid effect in the human body. Patients with Addison´s disease, primary adrenal insufficiency, with life-long glucocorticoid replacement therapy will undergo 2 treatment periods where their usual hydrocortisone treatment will be replaced with betamethasone in physiological and supra physiological doses. Blood, saliva, urine, health related Quality-of-life self-assessment forms, measurements of physical activity and sleep quality will be collected from both treatment periods.

What is being measured

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

  1. Protein profile changes between physiological and supra physiological doses of betamethasone.

    By using mas spectrometry, protein profile changes in blood, urine and saliva will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

    Measured: Changes in proteome (g/dl or umol/l) during 7 days of treatment with two different doses of betamethasone

  2. Metabolite profile changes between physiological and supra physiological doses of betamethasone.

    By using mas spectrometry, metabolite profile changes in blood, urine and saliva will be identified at four timepoints: after 3 hours and after 7 days during treatment with betamethasone in a physiological dose and after 3 hours and after 7 days during treatment with betamethasone in a supra physiological dose.

    Measured: Changes in metabolome (units depending on the kind of metabolome) during 7 days of treatment with two different doses of betamethasone

Secondary outcomes (10)
  1. Messenger RNA (mRNA)/miRNA profile changes between physiological and supra physiological doses of betamethasone.

  5. Changes in self-reported Quality of Life between physiological and supra physiological doses of betamethasone using the Addison-specific Quality of Life questionnaire (ADDIQoL).

    Self-reported health-related quality of life and general well-being will be assessed using the ADDIQoL questionnaire after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

    Measured: Changes in units of the ADDIQoL questionnaire (units on a scale) after 7 days of treatment with two different doses of betamethasone

  6. Changes in self-reported Quality of Life between physiological and supra physiological doses of betamethasone using the Psychological General Well-being (PGWB) index.

    Self-reported health-related quality of life and general well-being will be assessed using the PGWB index after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

    Measured: Changes in units of the PGWB index (units on a scale) after 7 days of treatment with two different doses of dexamethasone

  7. Changes in self-reported quality of life and fatigue between physiological and supra physiological doses of betamethasone using the Fatigue impact scale (FIS)

    Self-reported health-related quality of Life, general well-being and fatigue will be assessed using the FIS questionnaire after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

    Measured: Changes in units in the FIS (units on a scale) after 7 days of treatment with two different doses of betamethasone

  8. Changes in self-reported quality of life and fatigue between physiological and supra physiological doses of betamethasone using the Functional Outcomes of Sleep Questionnaire (FOSQ).

    Self-reported health-related quality of life, general well-being and fatigue will be assessed using FOSQ after 7 days of treatment with a physiological dose of betamethasone and after 7 days of treatment with a supra physiological dose of betamethasone.

    Measured: Changes in units in the FOSQ (units on a scale) after 7 days of treatment with two different doses of betamethasone

  9. Changes in daily physical activity between physiological and supra physiological doses of betamethasone

    Daily physical activity will be objectively evaluated using a wrist accelerometer during 7 days of treatment with a physiological dose of betamethasone and during 7 days of treatment with a supra physiological dose of betamethasone.

    Measured: Changes in daily physical activity (units provided in connected software) after 7 days of treatment with two different doses of betamethasone

  10. Changes in sleep quality between physiological and supra physiological doses of betamethasone

    Sleep quality will be objectively evaluated using a wrist worn sleep monitor during the last night of a 7 day treatment period with a physiological dose of betamethasone and the last night of a 7 day treatment period with a supra physiological dose of betamethasone.

    Measured: Changes in sleep quality (measurements and units provided in connected software) after 7 days of treatment with two different doses of betamethasone

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Betamethasone in people with Addison Disease, run by Göteborg University at 1 site in Sweden.

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 7 inclusion and 11 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 24 Apr 2025. 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 Sweden. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Protein profile changes between physiological and supra physiological doses of betamethasone. (time frame: Changes in proteome (g/dl or umol/l) during 7 days of treatment with two different doses of betamethasone). The study lists 2 primary outcomes in all. 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 24 Apr 2025.
