Eligibility Criteria
Criteria
Inclusion Criteria:
-
Healthy subjects,aged ≥18 but ≤65，male and female.

Female and/or male subjects those meet the below criteria:
If a female subject of child bearing potential-agrees to use one of the accepted contraceptive regimens from at least 30 days prior to the administration of IMP,during the study,and for at least 3 months after the end of the study. An acceptable method of contraception includes one of the following:
Abstinence from heterosexual intercourse Hormonal contraceptives(brith control pills,injectable/implant/insertable hormonal birth control products, transdermal patch) Intrauterine device(with or without hormones) OR agrees to use a double barrier method (e.g. condom and spermicide) . If a female subject of non-childbearing potential - should be surgically sterile (i.e. has undergone complete hysterectomy, bilateral oophorectomy, or tubal ligation/occlusion) or in a menopausal state (at least 1 year without menses), as confirmed by Follicle-stimulating hormone (FSH) levels (≥ 40 mIU/mL).
