CATNIP is being conducted by the Immune Tolerance Network and sponsored by the National Institute of Allergy and Infectious Diseases (NIH funded)...
CATNIP is a clinical research trial which will test whether an experimental drug called AMG 157 given with cat allergy shots will help the cat allergy shots work. The researchers want to see if after just one year of treatment, which is less than the 2-3 year standard therapy for allergy shots, relief will continue for at least one more year after stopping both medications.
