Trial summary

Intravenous- injection of beta-1,3-glucan in human is known to induce T helper type 1 response, while oral uptake did not. It was examined whether superfine dispersed beta-1,3-glucan (SDG) contrived to absorbed by intestinal mucosa would alleviate allergic symptoms by per-oral ingestion Read more about this study

About this study

Official title: Alleviation of Cedar Pollen Induced Allergic Symptoms by Orally Taken Superfine Beta-1,3-Glucan - A Double-Blind Randomized Study

Intravenous- injection of beta-1,3-glucan in human is known to induce T helper type 1 response, while oral uptake did not. It was examined whether superfine dispersed beta-1,3-glucan (SDG) contrived to absorbed by intestinal mucosa would alleviate allergic symptoms by per-oral ingestion

Read the detailed description

Beta-1,3-glucan made from Japanese mushroom is commercially available for healthy foodstuffs. Allergy patients were orally administrated either SDG (n=30) or non-dispersed beta-1,3-glucan (NDG, n=30) and allergic symptoms were assessed clinically, by the double-blind, placebo-controlled, randomized study

  • beta-1,3-glucanDrug

What is being measured

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

  1. Symptoms were assessed clinically by score on a allergic symptom rating scale.

Secondary outcomes (2)
  1. Total IgE and allergen specific IgE were measured.

  2. The binding capacity of beta-1,3-glucan to peripheral CD14+ cells were assessed.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing beta-1,3-glucan in people with Allergic Conjunctivitis, run by Meiji University of Oriental Medicine at 1 site in Japan.

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 2 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: stopped early, as of the sponsor's last update on 7 Nov 2006. 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 Japan. 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 was stopped early. 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?

Symptoms were assessed clinically by score on a allergic symptom rating scale.. 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 NCT00276445, 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 7 Nov 2006.
