Outcome Measures

Primary Outcomes (1)

  • Change in German Cockroach-Specific Serum IgE Over Time

    Outcome is the ratio of geometric means for baseline versus 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 3 months of treatment

Secondary Outcomes (4)

  • Change in German Cockroach-Specific Serum IgG Over Time

    Baseline through 3 months of treatment

  • Change in German Cockroach-Specific Serum IgG4 Over Time

    Baseline through 3 months of treatment

  • Change in IgE Fragment Antibody Binding (FAB) Activity Over Time

    Baseline through 3 months of treatment

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

    Participant enrollment to end of study (up to 3 months post-baseline)

Study Arms (3)

Cockroach Sublingual Immunotherapy (SLIT) - Low Dose

EXPERIMENTAL

Glycerinated German cockroach (Blatella germanica) allergen extract administered sublingually with a maximally tolerated dose of 420 microliters daily

Biological: Cockroach Sublingual Immunotherapy (SLIT) - Low Dose

Placebo

PLACEBO COMPARATOR

Placebo administered sublingually not to exceed the maximally tolerated dose of either 1.) 420 microliters daily (placebo - low dose randomization) or 2.) 840 microliters twice daily (placebo - high dose randomization)

Other: Placebo

Cockroach Sublingual Immunotherapy (SLIT) - High Dose

EXPERIMENTAL

Glycerinated German cockroach (Blatella germanica) allergen extract administered sublingually with a maximally tolerated dose of 840 microliters taken twice daily

Biological: Cockroach Sublingual Immunotherapy (SLIT) - High Dose

Interventions

Participants are randomized to receive daily doses of glycerinated German cockroach (Blattella germanica) allergenic extract formulated in 50% glycerin at a concentration of 1:20 weight per volume \[w/v\] placed under the tongue (sublingual route) to dissolve. The treatment course and study duration was 3 months. Note: The extract was also administered during the preliminary dosing visits, up to three escalating doses, or until the maximum study dose (420 microliters, 1:20 w/v) was achieved.

Also known as: Blattella germanica
Cockroach Sublingual Immunotherapy (SLIT) - Low Dose
PlaceboOTHER

Participants are randomized to receive either daily (low dose) or twice-daily (high dose) placebo treatment placed under the tongue (sublingual route) to dissolve. The treatment course and study duration was 3 months. Note: The placebo was also administered during the preliminary dosing visits, up to three or seven escalating doses, or until the maximum study dose (420 or 840 microliters, 1:20 weight per volume \[w/v\]) was achieved.

  • the participant's asthma must be well controlled as defined by: ii. a forced expiratory volume at one second (FEV1) greater than or equal to 80% predicted value with or without controller medication ii. albuterol use for no more than 3 days per week in each of the previous 2 weeks for asthma symptoms (not including exercise prophylaxis)
  • Are sensitive to German cockroach (Blattella germanica) as documented by a positive (\>/=3 mm greater than negative control) skin prick test result and detectable German cockroach specific IgE (\>/=0.35 kUA/L)
  • Have no known contraindications to therapy with glycerinated German cockroach allergenic extract or placebo
  • Parent or legally authorized representative (LAR) of child is willing to sign the written Informed Consent prior to initiation of any study procedure

You may not qualify if:

  • Are pregnant or lactating. Females must be abstinent or use a medically acceptable birth control method throughout the study (e.g. oral, subcutaneous, mechanical, or surgical contraception)
  • Cannot perform spirometry or peak flow at screening
  • Have an asthma severity classification at recruitment of severe persistent, using the National Asthma Education and Prevention Program (NAEPP) classification, as evidenced by at least one of the following:
  • requires a dose of greater than 500 mcg of fluticasone per day or the equivalent of another inhaled corticosteroid
  • have received more than 2 courses of oral or parenteral corticosteroids within the last 12 months
  • have been treated with depot steroids within the last 12 months
  • have been hospitalized for asthma within the 6 months prior to recruitment
  • have had a life-threatening asthma exacerbation that required intubation, mechanical ventilation, or that resulted in a hypoxic seizure within 2 years prior to recruitment
  • Do not have access to a phone (needed for scheduling appointments)
  • Have received allergen immunotherapy in the last 12 months prior to recruitment or who plan to initiate or resume allergen immunotherapy during the study
  • Have previously been treated with anti-IgE therapy within 1 year of recruitment
  • Have received an investigational drug in the 30 days prior to recruitment or who plan to use an investigational drug during the study
  • Have in the last 3 months prior to recruitment experienced on average \>/=1 day per week any of the symptoms below:
  • nausea or vomiting
  • abdominal pain or cramps severe enough to interfere with daily activities (excluding those associated with menstruation).
  • +8 more criteria
