PD-1 Antibody Combined Neoadjuvant Chemotherapy for Ovarian Cancer

A Phase II Study of PD-1 Antibody Plus Neoadjuvant Chemotherapy for Advanced-stage Ovarian Cancer (Z2HOC-01)

The main purpose of this study is to validate the efficacy and safety of anti-PD-1 in combination with neoadjuvant chemotherapy in women with advanced ovarian cancer.

5. Subjects with active hepatitis B (defined as positive hepatitis B virus surface antigen [HBsAg] test result and HBV-DNA test value higher than the upper limit of normal value in the laboratory of the research center) or hepatitis C (defined as positive hepatitis C virus surface antibody [HCSAB] test result and positive HCV-RNA test result).
6. Known human immunodeficiency virus (HIV) infection (known to be HIV positive).
7. Have received live vaccine within 30 days before the first administration.This includes but is not limited to the following: mumps, rubella, measles, varicella/herpes zoster (varicella), yellow fever, rabies, BCG and typhoid vaccines (inactivated virus vaccines are allowed).
