About

This is a single arm, multi center, exploratory clinical study to evaluate the efficacy and safety of fluzoparide combined with alpatinib as neoadjuvant therapy in patients with BRCA1/2 gene mutation or HRD gene mutation, advanced ovarian cancer, primary peritoneal cancer, fallopian tube cancer ((FIGO stage III or IV), who can not achieve R0 tumor reduction surgery after imaging evaluation or laparoscopic evaluation .

Enrollment: 35 estimated patients

Sex: Female

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
