abstinence is the usual lifestyle of the subject and the preferred method of
contraception, abstinence can be accepted as a method of contraception.

for adrenal or pituitary insufficiency) are not considered systemic treatments;

intervention before starting treatment (ie, =1 or reaching baseline, excluding fatigue
or alopecia);
14. Other malignant tumors were diagnosed within 5 years prior to the first dose, with the
exception of radical cutaneous basal cell carcinoma, cutaneous squamous cell
carcinoma, and/or radically resected carcinoma in situ;
15. Active central nervous system (CNS) metastasis and / or cancerous meningitis. Patients
with treated brain metastases who have remained clinically stable for at least 2 weeks
and have no new or advanced brain metastases may be enrolled and discontinued hormone
therapy 3 days prior to the first study drug. Patients with known untreated,
asymptomatic brain metastases can be enrolled, but regular imaging assessments of the
brain must be performed.

presence of interstitial lung disease 1 year before the first dose;
17. There are active infections that require systemic treatment;
