What is being measured

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

  1. Average Rhinoconjunctivitis Total Symptom Score (ARTSS)

    Average Rhinoconjunctivitis Total Symptom Score during the pollen period while participant on treatment.

    Participants assessed daily, during the pollen period, 6 rhinoconjunctivitis symptoms (sneezing, rhinorrhea, nasal pruritus, nasal congestion, ocular pruritus and watery eyes) each symptom is scored as follows: 0: no symptoms, 1: mild symptoms, 2: moderate symptoms, 3: severe symptoms. The sum of the 6 symptoms is the Rhinoconjunctivitis Total Symptom Score (RTSS) (range 0-18). The lower the score, the better the outcome.

    Measured: Pollen period (average of 38.6 days)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 300 IR grass pollen allergen extract tablet in people with Allergy, run by Stallergenes Greer at 1 site in Germany.

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 1 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 26 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 Germany. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 26 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 Rhinoconjunctivitis Total Symptom Score (ARTSS) (time frame: Pollen period (average of 38.6 days)). 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 NCT00409409, 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 26 May 2016.
