• Participant has a lower respiratory tract infection that required antibiotics within 6 weeks prior to Screening.

Other illness

• Participant has a known hypersensitivity to any component of the formulation of solrikitug, including any of the excipients, or a history of anaphylactic reaction to any therapeutic monoclonal antibody.
• Participant has history or evidence of any clinically significant cardiovascular, hematologic, hepatic, immunologic, metabolic, urologic, neurologic, dermatologic, psychiatric, renal and/or other major disease or malignancy, or any other condition that in the opinion of the Investigator or Medical Monitor might obfuscate the study data.

• Documented diagnosis of COPD for at least 12 months prior to Screening, defined by the GOLD Guidelines (2023), and elevated blood eosinophils at screening.
• At Screening FEV1/FVC ratio must be \<0.70, and Post-bronchodilator FEV1 must be ≥40% to \<80% predicted normal value calculated using Global Lung Function Initiative (GLI) reference equations (Cooper et al 2017).
