Texan Allergy & Sinus Center Mountain Cedar Intra-Lymphatic Immunotherapy Study

Mountain Cedar pollen allergenic extract is an FDA-approved, commercially available product for diagnosis and hypo-sensitization treatment of allergies. The labeled use is deep subcutaneous or percutaneous injection. Hyposensitization treatment is typically a series of 30 - 70 injections over 3 - 5 years into the upper aspect of the arm. This investigation is a proof-of-concept study to evaluate an alternative hyposensitization regimen of 3 injections directly into an inguinal lymph node.

The control group will receive a regimen of 3 injections of diluent (placebo) directly into an inguinal lymph node on the same schedule as the active treatment group.
