- Participant has a history or current evidence of a serious and/or unstable cardiovascular, respiratory, gastrointestinal, hematologic, autoimmune, blood dyscrasias or other medical disorder, including psychiatric disorders, cirrhosis, or malignancy.
- Participant has a history or presence of proteinuria, chronic kidney disease, disease requiring immunosuppressive therapy (including systemic steroids), or is considered to be immunosuppressed for any other reason.
- History of a previous severe allergic reaction with generalized urticaria; angioedema or anaphylaxis.
- Known immunodeficiency disorder.
- History of chronic infection or any infection requiring hospitalization or treatment with antivirals, antibiotics, or antifungal therapy within 30 days prior to administration of the study intervention.

- Known hepatic or biliary abnormalities.
- Additional exclusion criterion for Part A and Part B (participants with participants with specific autoimmune disease may apply depending upon the autoimmune condition).
Protocol Summary
