Sublingual Cockroach Safety in Adults With Cockroach Allergy & Perennial Allergic Rhinitis With or Without Asthma

Initially each subject underwent a 1-day, 8-dose escalation (e.g., one dose of placebo, 0.14 milliliters \[mL\], followed by 7 escalating doses of Glycerinated German Cockroach Allergenic Extract until the Maximum Study Dose \[0.42 mL, 1:10 wt/vol\] or Maximum Tolerated Dose was achieved). This maximum dose became the daily dose - maintenance dose- of Glycerinated German Cockroach Allergenic Extract for the following 14 days.The maintenance dose of 0.42 mL was calculated to contain 3685 bioequivalent allergy units (BAU), with approximately 4.2 mg of German cockroach allergen Bla g 2 and 50 mg of Bla g 1 per dose. Route of administration: sublingual-oral route.

Placebo was administered only as the first dose (e.g., representing no Glycerinated German Cockroach bioequivalent allergy units) during the initial 1-day, 8-dose escalation, otherwise referred to as the Preliminary Dosing Visit. Refer to the Glycerinated German cockroach allergenic extract treatment for more details. Route of administration: sublingual-oral route.
