Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 year to 20 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult

Who may be able to join

  • Age = 1-20 years
  • Diagnosed or suspected cereal allergy (at least to one of the following cereals wheat, barley or rye)
  • Response to cereal proteins confirmed within 2 months in an oral food challenge (OFC)* OR response to cereal proteins confirmed in an OFC more than 2 months ago but clinically verifiable and documented ongoing cereal allergy at the time of inclusion OR diagnosis confirmed in an OFC with wheat performed as part of the study procedures.
  • Voluntarily signed informed consent (including willingness to refrain from cereal containing foods for 1 week before intervention period and be exposed to cereal proteins in the test for eligibility)

Who cannot join

  • Complex food allergy which make elimination diet impossible to accomplish
  • Patients experiencing unstable or exacerbated atopic disease, such as asthma, atopic dermatitis (AD), urticaria, or allergic rhinitis.
  • Diseases and conditions that might affect safety. Patients should not be challenged if they have chronic medical the event of anaphylaxis/treatment of anaphylaxis. Examples of such conditions include unstable angina pectoris, cardiac disease or dysrhythmias, severe chronic lung disease.
  • Pregnancy should be ruled out by testing or based on history (e.g, before menarche) as appropriate
  • Use of oral corticosteroids. Inhaled and topical steroids or anti-inflammatory medications, such as calcineurin inhibitors or leukotriene antagonists and b-agonists, used at the lowest doses possible and on an established schedule by using fixed doses of medication to maintain a low and stable baseline of atopic disease. Latter medication can usually be continued because their use is unlikely to significantly influence challenge outcomes and their withdrawal might result in exacerbations, affecting disease management and challenge interpretation.
  • Use of antihistamines during the last 4 days before DBPC challenge or period of 5 half-lives of specific agent.
Show all 9Show fewer
  • Prolonged high dose steroids, omalizumab, or possibly other new drugs to control atopic disease upon decision of investigator.
  • Aspirin/nonsteroidal anti-inflammatory drugs, angiotensin converting enzyme inhibitors, alcohol, antacids and β-blockers upon the decision of the investigator
  • Any chronic condition or its medication that affect immune system

About this study

Official title: Randomized, Double-blind, Placebo Controlled Food Challenge for the Assessment of Non-allergenicity of Refined Barley Starch in Cereal Allergic Patients

Aim of the present study is to verify in a double-blind placebo controlled food challenge (DBPCFC) test that highly purified barley starch ingredient do not cause allergic reaction in subjects most potential to get allergic reaction due to ingredient. Hypothesis is that none of the cereal (mostly primarily wheat) allergic subject recruited to the study will obtain allergic reaction neither to placebo nor to the test ingredient. Scoring of symptoms during the challenges will be based on PRACTALL.

Being tested
Barley starch, Maize starch

What is being measured

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

  1. Challenge outcome according to PRACTALL -score

    Allergic reaction to active or placebo. Scoring and decision making based on PRACTALL as defined by Sampson et al., J Allergy Clin Immunol. 2012 Dec;130(6):1260-74.

    Measured: 12-24 days (including 2 blinded challenges)

Secondary outcomes (2)
  1. Severity of atopic dermatitis according to SCORAD-index

    Worsening of atopic dermatitis

    Measured: 12-24 days (including 2 blinded challenges)

  2. Symptom diary

    Subjective symptoms based on diary

    Measured: 12-24 days (including 2 blinded challenges)

Questions about this trial

What is this clinical trial studying?

A study testing Barley starch and Maize starch in people with Allergy;Food and Allergy Wheat, run by Lyckeby Starch AB at 1 site in Finland.

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 4 inclusion and 9 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: paused, as of the sponsor's last update on 5 Mar 2019. 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 Finland. 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?

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?

Challenge outcome according to PRACTALL -score (time frame: 12-24 days (including 2 blinded challenges)). 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 5 Mar 2019.
