Subjects who are vaccinated with live vaccine within 30 days before the first dose, or plan to be vaccinated with live vaccine during the study period.
Has received strong cytochrome P450 (CYP3A4) inhibitors or inducers, or has received BCRP inhibitors within 2 weeks prior to the first dose.
Subjects who received any chemotherapy, radiotherapy, immunotherapy, or biologic therapy treatment within 4 weeks; or who received any small molecular tyrosine kinase inhibitor, antitumor hormonal therapy, system immune-stimulator, or therapy with traditional Chinese medicines approved for antitumor treatment, etc. within 2 weeks before the first dose.
Has an active infection requiring systemic therapy.
Subjects with the disease that requires systemic corticosteroid therapy (prednisolone or equivalent dose of similar drugs at a dose of >10 mg/d) or other immunosuppressive therapy within 14 days before the first dose.
Is currently participating and receiving study therapy in a study of an investigational agent or has participated and received study therapy in a study of an investigational agent or has used an investigational device within 28 days of fist dose.
Before the first dose, the subject's condition deteriorates rapidly.
