- People who have been diagnosed with chronic obstructive pulmonary disease (COPD) or another lung condition that may affect lung function, as assessed by the trial doctor
- People who have had an active or acute infection requiring antibiotic or antiviral treatment in the 4 weeks before joining up until the time of being assigned to a treatment group
- People with a known or suspected history of a weakened immune system, including a history of serious or unusual infections, or who experience infections that are unusually frequent, long-lasting, or recurring
- People with a history of cancer, unless: they had basal cell skin cancer, a localised skin squamous cell cancer, or cervical carcinoma in situ and completed curative treatment at least 12 months before joining; or they had another type of cancer and completed curative treatment at least 5 years before joining

- People who test positive for HIV or syphilis at screening
- People with chronic hepatitis B or hepatitis C infection
- People with abnormal liver or kidney function results above specified laboratory thresholds (confirm with trial site)
- People who have a high eosinophil count (a type of white blood cell) caused by a condition other than asthma — for example, a parasitic worm infection — that has not been adequately treated or has not responded to treatment
- People who are allergic or sensitive to any ingredient in the study drug (CM310 injection) or placebo, or who have a history of severe allergic reactions or anaphylactic shock to medicines
- People who have taken part in another clinical trial of a medicine or medical device within 3 months before joining, or who are still within a follow-up period or 5 half-lives of a trial drug from a previous study (whichever is longer)
