About this study

Official title: Effect of Supplementary Treatment With Agaricus Blazei Based Mushroom Extract, Andosan, on Patients With Asthma and Allergy

Examine whether daily oral ingestion of a immunomodulatory mushroom extract (AndoSanTM) in patients with asthma and allergy, undergoing allergen specific immunotherapy experience clinical and biochemical improvement in their disease.

A prospective randomised study comparing the mushroom extract with placebo.

Read the detailed description

Asthma and allergy are increasing in Norway and Western countries. Treatment is still mostly symptomatic. Extracts of the immunomodulatory and edible mushroom Agaricus blazei, such as Andosan™, have been shown to protect against asthma and allergy in murine models by changing the T helper cell 1(upregulation)-T helper cell 2 (downregulation) balance in the immune system. Positive effects on allergy were also shown in a RCT on blood donors with selfreported allergy. Andosan™ is produced in Japan and approved as food (mushroom juice) in Norway.

The aim of this study is to examine whether Andosan™ i) has similar clinical effects against allergy and asthma in patients as it has in mice, and as earlier shown in a study on blood donors with allergy ii) wether patients taking Andosan has any clinical impact on asthma while taken as supplementary treatment in addition to other medication compared to a placebo group while going through allergen specific immunotherapy (ASIT).

If the extract shows effect on these patients it support the hypotheses that Andosan helps against atopic diseases and facilitate the shift from Th-2 to Th-1 responses at a cellular level.

    Measured: 20 days to four weeks

  2. Questionnaire ACT

    Change in asthma symptoms, as measured by the asthma control test

    Measured: four weeks

  3. Questionnaire RQLQ

    Change in burden of asthma symptoms measured by RQLQ (Respiratory questionnaire of life quality)

    Measured: four weeks

  4. Passive basophil cell activation in serum

    Difference in activation of basophil cells measured in serum before and after intervention

    Measured: four weeks

  5. Immunoglobulin E in serum

    difference in concentration before and after intervention

    Measured: four weeks

Questions about this trial

What is this clinical trial studying?

A study testing Andosan in people with Allergic Asthma and Allergic Rhinoconjunctivitis, run by University Hospital, Akershus 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 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 18 Jun 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. 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.

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?

FEV1 (time frame: 20 days). 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 18 Jun 2024.
