Live vaccines are not allowed during the study or for 20 weeks after the last dose of study drug
• Subject has received any investigational drug or experimental procedure within 90 days or 5 half-lives, whichever is longer, prior to IMP administration
• Subject has a known hypersensitivity to any components of the IMP as stated in this protocol
• Subject has a current or past history of gastrointestinal ulceration or other gastrointestinal disease
• Subject has cardiovascular or cerebrovascular disease, including hypertension, angina, ischemic heart disease, transient ischemic attacks, stroke, peripheral arterial disease sufficient to cause symptoms, and/or requires therapy to maintain stable status

• Study participant has a history of a positive tuberculosis (TB) test or evidence of possible TB or latent TB infection at the Screening Visit
• Subject has concurrent acute or chronic viral hepatitis B or C or human immunodeficiency virus (HIV) infection
• Subject has 12-lead ECG with changes considered to be clinically significant at Screening Visit and Day -1
• Subject has active neoplastic disease or history of neoplastic disease within 5 years of Screening Visit (except for basal or squamous cell carcinoma of the skin or carcinoma in situ that has been definitively treated with standard of care)

Due to the small sample size in this trial, Individual Patient Data cannot be adequately anonymized and there is a reasonable likelihood that individual participants could be re-identified. For this reason, data from this trial cannot be shared.
