Tozorakimab for treating chronic obstructive pulmonary disease

Tozorakimab is being developed as a treatment for chronic obstructive pulmonary disease (COPD). COPD is a long-term lung condition that causes breathing problems, coughing, sputum production and chest tightness. It happens when the airways become inflamed, damaged, and narrowed over time. People with COPD often have flare-ups, called exacerbations, where their symptoms suddenly get worse. These flare-ups can lead to hospital stays and lower quality of life. There is currently no cure for COPD, but treatments are taken to manage symptoms and support quality of life. Current treatments may not prevent all types of flare-ups, so there is a need for new medicines that can help reduce how often these flare-ups happen.
