About this study
Official title: A Randomised, Double-blind, in Parallel Groups Placebo-controlled, Mono-centre, Phase I Study to Assess After Allergen Challenge in an Allergen Exposition Chamber the Effect and Its Time Course of Sublingual Immunotherapy (SLIT) Administered as 300IR Allergen-based Tablets Once Daily to Adults Suffering From Grass Pollen Rhinoconjunctivitis
The objective of this study is to assess the effect of grass pollen extract SLIT tablets on the Rhinoconjunctivitis Total Symptom Score (RTSS) of the six rhinoconjunctivitis symptoms in response to grass pollen challenge after one week, one, two and four months of treatment in patients suffering from Seasonal Allergic Rhinoconjunctivitis (SAR) due to grass pollen.
Read the detailed description
The purpose of this study is to determine whether SLIT tablets are effective on symptoms of allergic rhinitis compared to placebo in patients suffering from allergic rhinitis to grass pollen when exposed in an allergen chamber and also to determine the onset of action of SLIT tablets on allergic rhinitis symptoms.

What is being measured
The primary outcome is the main question the study is designed to answer.
Average of Rhinoconjunctivitis Total Symptom Score (ARTSS) ]0-4] Hours
The primary efficacy variable was the Average of Rhinoconjunctivitis Total Symptom Score (ARTSS) during the four-hour (]0-4] hours) grass pollen allergen challenge at end point (after four months of treatment) of the 6 rhinoconjunctivitis symptoms (sneezing, rhinorrhea, nasal pruritus, nasal congestion, ocular pruritus and watery eyes). The severity of each symptom was evaluated by the subject, before allergen exposure and every 15 minutes during allergen challenge on a scale of 0 to 3; 0: no symptoms, 1: mild symptoms, 2: moderate symptoms, 3: severe symptoms, total score range was 0 to 18. The ARTSS ]0-4] hours was calculated as the mean of the RTSSs at each timepoint during the allergen challenge (i.e., 16 timepoints from 15 minutes to 4 hours) after 4 months of treatment (endpoint). The lower the score, the better the outcome.
Measured: 4 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing 300 IR grass pollen allergen extract tablet in people with Seasonal Allergic Rhinitis, run by Stallergenes Greer at 1 site in Austria.
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 5 inclusion and 3 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 23 May 2016. 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 Austria. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 May 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Average of Rhinoconjunctivitis Total Symptom Score (ARTSS) ]0-4] Hours (time frame: 4 months). 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 NCT00619827, which also lists 3 linked publications.
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 23 May 2016.
