About this study

Official title: A Randomised, DB, Plcb Controlled, Multicentre, Multinational Phase II/III Study to Assess the Efficacy and Safety of Three Different Dose Regimens of Oralgen Grass Pollen in Patients With Grass Pollen Related Allergic Rhinoconjunctivitis

The study is assessing efficacy and safety of three different dosage regimens of grass pollen sublingual immunotherapy in adult patients suffering from grass pollen related rhinoconjunctivitis.

Read the detailed description

Patients with seasonal grass pollen related rhinoconjunctivitis will be randomized to one of four treatment groups at 41 centres in Europe. Each treatment group will consist of approximately 150 patients and 150 patients will be randomized to a placebo group. The study will consist of a screening phase, a treatment phase and a variable maintenance period.

What is being measured

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

  1. Primary efficacy variable is based on pollen season rhinoconjunctivitis Total Symptom Score (PS.RTSS)

    Measured: One year

Secondary outcomes (1)
  1. Diarised Period RTSS on severity of rhinoconjunctivitis scores and rescue medication usage will be calculated to assess efficacy. Safety will be assessed through AE profile, the assessment of routine safety tests.

    Measured: one year

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Oralgen and grass pollen extract in people with Allergic Rhinoconjunctivitis, run by Artu Biologicals at 40 sites in 7 countries.

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 9 inclusion and 15 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 5 May 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 sites in Czechia, Bulgaria, Germany, Hungary, Lithuania and 2 more countries. 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 combined 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.

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?

Primary efficacy variable is based on pollen season rhinoconjunctivitis Total Symptom Score (PS.RTSS) (time frame: One year). 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 May 2010.
