About this study

Official title: Phase IIb Study on the Safety and Efficacy of BM32, a Recombinant Hypoallergenic Vaccine for Immunotherapy of Grass Pollen Allergy

The study will evaluate the efficacy and safety of BM32 in grass pollen allergic subjects. It will test the hypothesis that either of two doses of BM32 will lead to a sustained relief off allergy symptoms over a two year study period.

Read the detailed description

The present study is designed to evaluate the efficacy and safety of a treatment with the recombinant vaccine BM32 during two consecutive grass pollen seasons. Efficacy evaluation will be performed on the basis of allergy symptoms and use of relief medication as well as based on immunological parameters. After patient assessment during a screening season, patients will be randomized to one of two doses of BM32 or placebo. Patients will receive three injections of BM32 pre-season and one post-season boost injection to maintain optimal allergen specific IgG responses. Outcome will be measured after both seasons individually.

What is being measured

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

  1. Mean daily combined symptom medication score (SMS)during the peak of the pollen season.

    The score will be recorded daily for the 30-45 days with the highest pollen count in each center

    Measured: Up to 3 months

Secondary outcomes (14)
  1. Vital functions

    Measured: Up to 22 months

  2. Safety laboratory hematology

    Measured: up to 22 months

  3. Meal level of "well-being" measured by a visual analog scale (VAS) during grass pollen season

    The VAS will be recorded daily during the grass pollen seasons of 2013 and 2014

    Measured: Up to 8 months

  4. Number of "bad days" during the peak pollen season and the whole pollen season

    The number of bad days will be recorded daily during the grass pollen seasons of 2013 and 2014

    Measured: Up to 8 months

  5. Number of symptom-free days during the peak pollen season and the whole pollen season

    The mesure will be recorded daily during the grass pollen seasons of 2013 and 2014

    Measured: Up to 8 months

  6. Rhinoconjunctivitis quality of life evaluation by RQLQ questionnaire during pollen season

    The questionnaire will be completed on a weekly basis during the pollen seasons of 2013 and 2014.

    Measured: Approx. 22 months

  7. Mean asthma score during pollen season

    The score will be recorded on a daily basis duirng the pollen seasons of 2013 and 2014

    Measured: Up to 8 months

  8. Mean allergy specific IgG and IgE antibodies before and after vaccination

    These antibody levels will be recorded a total of five times (01/2013, 04/2013, 09/2013, 01/2014 and 04/2014)

    Measured: Up to 16 months

  9. Mean daily symptom and medication score during the whole pollen season

    The score will be recorded daily approximately during May 2013 - August 2013 and May 2014 - August 2014

    Measured: Up to 8 months

  10. Mean daily symptom score (SS) and medication score (MS) during the peak pollen season and the whole pollen season

    The scores will be recorded daily during the pollen seasons of 2013 and 2014

    Measured: Up to 8 months

  11. Skin reactivity to grass pollen extract by titrated skin prick testing

    The titrated skin prick testing will be applied a total of 4 times before and after the pollen seasons of 2013 and 2014.

    Measured: Up to 15 months

  12. Results of physical examination

    Measured: up to 22 months

  13. Safety Laboratory: Blood biochemistry

    Measured: Up to 22 months

  14. Safety laboratory: Urine analysis

    Measured: up to 22 months

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 11 sites in 6 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 4 inclusion and 21 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 18 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in Germany, Austria, Belgium, Denmark, Netherlands and 1 more country. 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?

Mean daily combined symptom medication score (SMS)during the peak of the pollen season. (time frame: Up to 3 months). 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 18 Dec 2015.
