About this study

Official title: Safety and Dose Finding Study Based on the Effects of Three Subcutaneous Injections of BM32, a Recombinant Hypoallergenic Grass Pollen Vaccine, on Responses to Allergen Challenge by Skin Testing and in the Vienna Challenge Chamber (VCC) as Well as Immunological Response in Subjects Know to Suffer From Grass-pollen Induced Allergic Rhinitis

The study will evaluate the dose response of immunotherapy against grass pollen allergy using the recombinant grass pollen vaccine BM32. Efficacy will be analyzed by:

  • skin prick testing
  • grass pollen inhalation challenge
  • antibody responses. In addition, the safety of subcutaneous application of BM32 will be evaluated.

What is being measured

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

  1. Minimum effective dose for reduction of total nasal symptom score (TNSS) after inhalation challenge with grass pollen

    Difference in the total Nasal Symptom Score (TNSS) between spending 6 hrs in the Vienna Challenge Chamber (VCC) at screening and spending 6 hrs in the VCC four weeks after the last subcutaneous injection of BM32.

    Measured: Baseline and 14 weeks

Secondary outcomes (12)
  1. Minimum Effective dose for reduction of Total Non-Nasal Symptom Score (TNNSS) following inhalation challenge with grass pollen

    Measured: Baseline and 14 weeks

  2. Minimum effective dose for reduction of Global symptom Score upon inhalation challenge with grass pollen

    Measured: Baseline and 4 weeks after final s.c. injection

  3. Minimum effective dose for reduction of nasal airflow resistance after inhalation challenge with grass pollen

    Measured: Baseline and 14 weeks

  4. Minimum effective dose to reduce skin reaction to grass pollen allergen upon skin prick testing

    Measured: Baseline and 14 weeks

  5. Difference in FEV1 and FEV/FVC between screening and completion of vaccination

    Measured: Baseline and 14 weeks

  6. Frequency of local reactions to treatment

    Measured: average of 8 weeks from 1st to last injection

  7. Change in allergy specific total IgG

    Measured: Baseline and average of 12 weeks after randomization

  8. Change in allergy specific IgE

    Measured: Baseline and average of 12 weeks after randomization

  9. Frequency of systemic reactions to treatment

    Measured: average of 8 weeks from 1st to last injection

  10. Severity of local reactions to treatment

    Measured: Average of 8 weeks from 1st to last injection

  11. Severity of systemic reactions to treatment

    Measured: Average of 8 weeks from 1st to last injection

  12. Frequency of adverse events

    Measured: average of 14 weeks from 1st injection

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing BM32 in people with Grass Pollen Allergy, run by Biomay AG 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 14 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 14 Jan 2013. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Minimum effective dose for reduction of total nasal symptom score (TNSS) after inhalation challenge with grass pollen (time frame: Baseline and 14 weeks). 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 NCT01445002, 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 14 Jan 2013.
