Summary
This study tests a new antibody drug for people whose seasonal allergies (hay fever) are not controlled by standard treatments. The drug targets a protein involved in allergic inflammation. About 120 adults will receive either the antibody or a placebo, and researchers will measure changes in nasal symptoms like sneezing and congestion after two weeks.
