About the RAINER Asthma Research Study

This study is testing an investigational drug called solrikitug to see if it is safe and helps adults with asthma. The medication works by stopping the body’s immune system from causing swelling and asthma flare-ups.

Asthma can cause trouble breathing, coughing, wheezing, chest tightness, tiredness, and feeling worried. The RAINIER study hopes to make asthma symptoms better.

This study is now closed.
