NCT00829985

Brief Summary

There is currently no effective way to prevent development of allergic rhinitis (nasal allergies) and asthma and no cure. Sublingual immunotherapy (SLIT), a type of therapy in which allergens are placed under the tongue, may be a way to control and possibly prevent allergic rhinitis and asthma. However, detailed research of this approach is limited. The purpose of this study is to evaluate the safety and efficacy of a sublingual cockroach extract given to adults with perennial allergic rhinitis, asthma, or both.

Outcome Measures

Primary Outcomes (1)

  • Difference in German Cockroach-Specific Serum IgE Over Time

    Outcome is the ratio of geometric means for baseline German cockroach-specific serum Immunoglobulin E (IgE) vs. post-baseline German cockroach-specific serum IgE. This result is an indicator of immune modulation over time, however its clinical significance is unclear.

    Baseline through 6-months of treatment

Secondary Outcomes (4)

  • Difference in German Cockroach-Specific Serum IgG4 Over Time

    Baseline through 6-months of treatment

  • Change in IgE Fragment Antibody Binding (FAB) Activity (30 Micrograms/mL Cockroach Allergen Extract)

    Baseline through 6-months of treatment

  • Change in IgE Fragment Antibody Binding (FAB) Activity (60 Micrograms/mL Cockroach Allergen Extract)

    Baseline through 6-months of treatment

  • Percent of Participants With the Occurrence of Adverse Events (AE)

    Participant enrollment to end of study (up to 6 months post-baseline)

Study Arms (2)

Glycerinated German Cockroach Allergenic Extract

EXPERIMENTAL

Participants with German cockroach allergy and mild to moderate asthma, rhinitis, or both self-administered concentrated (1:20 weight per volume \[w/v\]) daily doses of glycerinated German cockroach allergenic extract (50% glycerin) placed under the tongue (sublingually) to dissolve. The treatment course and study duration was 6 months. Note: The extract was also administered during the preliminary dosing visits, up to five escalating doses, or until the maximum study dose (420 microliters, 1:20 w/v) was achieved.

Biological: Glycerinated German Cockroach Allergenic Extract

Placebo

PLACEBO COMPARATOR

Participants with German cockroach allergy and mild to moderate asthma, rhinitis, or both self-administered daily doses of placebo placed under the tongue (sublingually) to dissolve. The treatment course and study duration was 6 months. Note: The placebo was also administered during the preliminary dosing visits, up to five escalating doses, or until the maximum study dose (420 microliters, 1:20 weight per volume \[w/v\]) was achieved.

Biological: Placebo

Interventions

Concentrated (1:20 w/v) daily doses of glycerinated German cockroach allergenic extract placed under the tongue to dissolve. The extract is also administered during the preliminary dosing visits in up to five escalating doses or until the maximum study dose (420 microliters, 1:20 w/v) is achieved.
