Testing a new inhaled medication for lung disease

This is an early-stage study testing a new medication called HRS-9821 that you would inhale (breathe in) as a powder or liquid mist. The trial is checking whether this medication is safe and how your body handles it, first in healthy volunteers and then in people diagnosed with chronic obstructive pulmonary disease (COPD), a condition that makes it hard to breathe.

COPD is a serious lung disease that affects millions of people, and current treatments don't work well enough for everyone. This trial is exploring whether this new inhaled medication could offer a better way to help people breathe easier and manage their symptoms.
