Official title

A Phase II Observer-blind, Randomized, Placebo-Controlled Study of the Efficacy, Safety, Tolerability, and Immunogenicity of Subcutaneously Administered Dynavax Amb a 1 Immunostimulatory Oligodeoxyribonucleotide Conjugate (AIC) in Ragweed-Allergic Adults (Sponsor's Protocol NRH01)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Various chemical modifications of allergens have been attempted to enhance efficacy, improve safety, and foster compliance with IT. These approaches have been unsuccessful - in that the allergenicity and immunogenicity have either decreased, or increased in tandem, with no resultant efficacy: safety benefit ratio. This study utilizes an adjuvant approach in which synthetic immunostimulatory DNA is conjugated to ragweed allergen in an attempt to modulate both the clinical and immunologic allergic response to ragweed exposure in ragweed-allergic patients with seasonal rhinitis.
