Investigator Mark Natter alerts us to an ongoing study by the National Institute of Allergy and Infectious Diseases (NIAID):
This study is ongoing, but not recruiting participants.
ClinicalTrials.gov Identifier: NCT00434421
Purpose: 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.
Intervention: Drug: Glycerinated German cockroach allergenic extract
