Official title
A Safety and Pilot Dosing Study for Sublingual-Oral Administration of Glycerinated German Cockroach Allergenic Extract in Pediatric and Adult Subjects With Cockroach Allergy and Perennial Allergic Rhinitis With or Without Asthma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Immunotherapy may help reduce symptoms of allergy and asthma. Problems concerning compliance and adverse events with subcutaneous allergen immunotherapy have generated interest in delivering immunotherapy sublingually (under the tongue). The purpose of this study is to evaluate the safety of a cockroach extract given sublingually to people with perennial (year-round) allergic rhinitis, with or without asthma.
