NCT01538979
First received: February 7, 2012
Last updated: January 10, 2013
Last verified: January 2013
  Purpose

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.

Further study details as provided by Biomay AG:

Primary Outcome Measures:
  • Mean daily combined symptom medication score (SMS)during the peak of the pollen season. [ Time Frame: Up to 3 months ] [ Designated as safety issue: No ]
    The score will be recorded daily for the 30-45 days with the highest pollen count in each center


Secondary Outcome Measures:
  • Vital functions [ Time Frame: Up to 22 months ] [ Designated as safety issue: Yes ]
  • Safety laboratory hematology [ Time Frame: up to 22 months ] [ Designated as safety issue: Yes ]
  • Meal level of "well-being" measured by a visual analog scale (VAS) during grass pollen season [ Time Frame: Up to 8 months ] [ Designated as safety issue: Yes ]
    The VAS will be recorded daily during the grass pollen seasons of 2013 and 2014

  • Number of "bad days" during the peak pollen season and the whole pollen season [ Time Frame: Up to 8 months ] [ Designated as safety issue: No ]
    The number of bad days will be recorded daily during the grass pollen seasons of 2013 and 2014

  • Number of symptom-free days during the peak pollen season and the whole pollen season [ Time Frame: Up to 8 months ] [ Designated as safety issue: No ]
    The mesure will be recorded daily during the grass pollen seasons of 2013 and 2014

  • Rhinoconjunctivitis quality of life evaluation by RQLQ questionnaire during pollen season [ Time Frame: Approx. 22 months ] [ Designated as safety issue: No ]
    The questionnaire will be completed on a weekly basis during the pollen seasons of 2013 and 2014.

  • Mean asthma score during pollen season [ Time Frame: Up to 8 months ] [ Designated as safety issue: No ]
    The score will be recorded on a daily basis duirng the pollen seasons of 2013 and 2014

  • Mean allergy specific IgG and IgE antibodies before and after vaccination [ Time Frame: Up to 16 months ] [ Designated as safety issue: No ]
    These antibody levels will be recorded a total of five times (01/2013, 04/2013, 09/2013, 01/2014 and 04/2014)

  • Mean daily symptom and medication score during the whole pollen season [ Time Frame: Up to 8 months ] [ Designated as safety issue: No ]
    The score will be recorded daily approximately during May 2013 - August 2013 and May 2014 - August 2014

  • Mean daily symptom score (SS) and medication score (MS) during the peak pollen season and the whole pollen season [ Time Frame: Up to 8 months ] [ Designated as safety issue: No ]
    The scores will be recorded daily during the pollen seasons of 2013 and 2014

  • Skin reactivity to grass pollen extract by titrated skin prick testing [ Time Frame: Up to 15 months ] [ Designated as safety issue: No ]
    The titrated skin prick testing will be applied a total of 4 times before and after the pollen seasons of 2013 and 2014.

  • Results of physical examination [ Time Frame: up to 22 months ] [ Designated as safety issue: Yes ]
  • Safety Laboratory: Blood biochemistry [ Time Frame: Up to 22 months ] [ Designated as safety issue: Yes ]
  • Safety laboratory: Urine analysis [ Time Frame: up to 22 months ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: BM32 low dose
7 subcutaneous injections of 20 micrograms over two grass pollen seasons
Biological: BM32
Subcutaneous injection of 20 micrograms of each of the protein components of BM32 adsorbed on 0.6 mg of aluminum hydroxide every 4 weeks for a total of 3 injections before each pollen season and one boost injection after pollen season
Experimental: BM32 high dose
7 subcutaneous injections of 40 micrograms over two grass pollen seasons
Biological: BM32
Subcutaneous injection of 40 micrograms of each of the protein components of BM32 adsorbed on 1.2 mg of aluminum hydroxide every 4 weeks for a total of 3 injections before each pollen season and one boost injection after pollen season
Placebo Comparator: Placebo
7 subcutaneous injections over a time span of two pollen seasons
Biological: Placebo
Subcutaneous injection of 1.2 mg of aluminum hydroxide suspension every four weeks before each pollen season and one injection after pollen season for a total of 7 injections

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.
