Type I HypersensitivityPhase 2NCT00113750
Induction of Immunogenicity With Different Doses of TreeMATA in Subjects Allergic to Tree Pollen
A Phase 2 study testing TreeMATA MPL in people with Type I Hypersensitivity, run by Allergy Therapeutics at 10 sites in United States.
Trial summary
Tree MATA (modified pollen allergen tyrosine adsorbate) has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to tree (birch, alder, and hazel) pollen.

About this study
Official title: A Multicenter, Single-Blind, Placebo-Controlled, Phase 2 Study to Evaluate the Induction of Immunogenicity With Different Doses of Tree MATA in Subjects Allergic to Tree Pollen
Tree MATA (modified pollen allergen tyrosine adsorbate) has been developed to provide pre-seasonal specific immunotherapy for patients with hypersensitivity to tree (birch, alder, and hazel) pollen. Different doses of Tree MATA will be administered and immunological changes following this treatment will be assessed.
Read the detailed description
Tree MATA MPL has been developed to provide pre-seasonal specific immunotherapy for patients with proven type I hypersensitivity to tree (birch, alder, and hazel) pollen.
The tree pollen extract is modified with glutaraldehyde to produce the active ingredient, an allergoid. This modification reduces the reactivity of the extract with IgE antibody, thus reducing the risk of side effects. However, a simultaneous reduction in other important immunological properties, such as IgG and T cell reactivities, is not seen.
MPL (Monophosphoryl Lipid A), a purified, detoxified glycolipid derived from the cell wall of Salmonella minnesota, is included in the product formulation as an adjuvant to increase the immunogenic effect of the product and to enhance the switch from an allergen-specific TH2 to a TH1-like T cell profile.
The purpose of this study is to assess specific immunological changes (IgG, IgG1, IgG4 and IgE) in allergic subjects following 2 subcutaneous injections of different doses of study medication (Tree MATA) or placebo administered 3 weeks apart. The immunological changes will be used to assess the performance of the R7 IgG reactivity assay over a range of clinically efficacious doses.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing TreeMATA MPL in people with Type I Hypersensitivity, run by Allergy Therapeutics at 10 sites in United States.
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 8 inclusion and 23 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 17 Jun 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Post-injection antibody response to birch. 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 17 Jun 2010.
