This early-stage trial tests an experimental RNA immunotherapy called ITI-9001 in adults with Japanese cedar pollen allergy. The treatment aims to retrain the immune system to reduce allergic reactions. Researchers are primarily checking safety and how well people tolerate the sh…

This study looks at the safety of a nasal spray called neffy compared to a standard epinephrine shot for treating allergic reactions. It involves 600 people aged 4 and older who have an allergic reaction during a food challenge or allergy shot session. The goal is to see if the s…

This study tests an injection called TQH2722 in 300 adults with seasonal allergic rhinitis (hay fever). The goal is to see if it safely eases symptoms like sneezing, stuffy nose, and itchy eyes when added to standard allergy treatments. Participants will receive the injection and…

This study tracks how adults with grass pollen allergy use Grassmuno® in everyday medical practice. Researchers will monitor treatment adherence and injection schedules over two years. The goal is to understand how well patients stick with the therapy and how it controls their sy…

This study tests a new nasal spray called ALDP001 for people with seasonal allergic rhinitis (hay fever). Researchers want to find the best dose and how often to use it to reduce symptoms like sneezing, stuffy nose, and runny nose. About 164 adults will take part, and their sympt…

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 measu…

This Phase 3 trial tests an injection called GR1802 for people with seasonal allergic rhinitis (hay fever) that is not well controlled by standard treatments. The drug is a lab-made antibody that blocks a key inflammation signal. About 150 adults will receive either GR1802 or a p…
