What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Grass pollen formulationBiological

    Also called specific immunotherapy

    Solution for sublingual application containing allergen extracts of 6 grass pollen species (Holcus lanatus, Dactylus glomerata, Lolium perenne, Phleum pratense, Poa pratensis, Festuca pratensis) pollen allergen extract.

    The study solution was applied sublingually, kept under the tongue for 3 minutes, and swallowed thereafter.

  • ComparatorOther

    Also called Specific Immunotherapy

    Solution for sublingual application containing Placebo. The study solution was applied sublingually, kept under the tongue for 3 minutes, and swallowed thereafter.

Liquid formulation of an extract of a 6 grass pollen mixtureExperimentalSublingual application containing allergen extracts of 6 grass pollen species (Holcus lanatus, Dactylus glomerata, Lolium perenne, Phleum pratense, Poa pratensis, Festuca pratensis) pollen allergen extract. The study solution was applied sublingually, kept under the tongue for 3 minutes, and swallowed thereafter. Initial treatment was applied on the first day of treatment with a starting dose of 25% of the maintenance dose. Increasing doses of 50% were applied with the second and 100% with the third dose to give the maximum (=maintenance) dose. This was followed by a daily patient selfadministered treatment with the maintenance dose.

What is being measured

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

  1. Symptom and Medication Score (SMS)

    The primary endpoint is the change of the area under the curve (AUC, derived from an analysis period of 42 days) of the daily sum of the Symptom and Medication Score (SMS) from the baseline measurement to the measurement after 1.5 years of therapy.

    Measured: 1.5 years of therapy

Secondary outcomes (1)
  1. Visual Rating Scale

    Patients' Assessment of severity of symptoms at the end of each season on a 10 points visual rating scale (VRS)

    Measured: 1.5 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Grass pollen formulation and Comparator in people with Grass Pollen Allergy, run by Allergopharma GmbH & Co. KG 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 1 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 24 Jan 2014. 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?

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?

Symptom and Medication Score (SMS) (time frame: 1.5 years of therapy). 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 NCT00264459, which also lists 2 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 24 Jan 2014.
