About this study

Official title: A Prospective, Randomized, Open, Multi-centre Study to Assess Safety of PURETHAL Birch Given With a Rush Up-dosing Regimen to Patients With Allergic Rhinitis/Rhinoconjunctivitis

This study investigates the safety of two up-dosing regimen. The safety of PURETHAL Birch will be evaluated in a rush regimen (maximum dose reached in 3 injections during 3 weeks) compared to the conventional regimen (maximum dose reached in 6 injections during 6 weeks).

The primary endpoint of the sudy is the comparison of the proportions of the patients who have successfully reached the maintenance dose between the two treatment regimes.

A similar previous study with PURETHAL Grasses has shown that the rush up-dosing scheme is as safe as the conventional up-dosing regime. Therefore it is expected that up-dosing with PURETHAL Birch according to the rush regimen is as safe as using the conventional regimen.

What is being measured

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

  1. Proportion of patients successfully reaching the maintenance dose

    Measured: 12 weeks

Secondary outcomes (2)
  1. Early and late local and systemic reactions

    Measured: 30 minutes after IMP injection and 24 hours after injection

  2. Immunological parameters (IgE, IgG)

    Measured: 10 weeks rush regime, 13 weeks conventional regime

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing PURETHAL Birch, 20.000 AUM/ml in people with Allergic Rhinitis and Allergic Rhinoconjunctivitis, run by HAL Allergy at 8 sites in Poland.

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 6 inclusion and 19 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 11 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Poland. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Proportion of patients successfully reaching the maintenance dose (time frame: 12 weeks). 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 11 Apr 2014.
