Who is this study for? Patients with platinum-sensitive recurrent ovarian cancer
What treatments are being studied? Anlotinib+Olaparib
Status: Recruiting

Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 2

PARP inhibitors have changed the treatment paradigm of ovarian cancer. Most patients using PARP(poly-ADP ribose polymerase) inhibitors will suffer different grades of adverse events(AEs), followed by dose reduction. It has not been reported whether the dose-reduced olaparib as maintenance treatment have an impact on efficacy. Both PAOLA-1 and AVANOVA 2 studies showed that combined PARP inhibitors and antiangiogenic drugs have synergistic anti-tumor effect. Anlotinib is a novel multi-target tyrosine kinase inhibitor that can inhibit VEGFR(vascular endothelial growth factor receptor), FGFR(fibroblast growth factor receptor), PDGFR(platelet-derived growth factor receptor) α/β, c-Kit, and Ret. And anlotinib has been approved as orphan drug designations for treatment of ovarian cancer by FDA in 2015. Previous studies showed that anlotinib had manageable toxicity and promising antitumor effect. Our study is expected to investigate the efficacy and safety of anlotinib combined with dose-reduced olaparib as maintenance treatment in platinum-sensitive recurrent ovarian cancer patients.

Participation Requirements
Sex: Female
Minimum Age: 18
Healthy Volunteers: No

• Subjects join the study voluntarily and sign informed consent;

• Female subjects are older than 18 years;

• ECOG(Eastern Cooperative Oncology Group) physical status score is 0-1;

• Life expectancy≥3 months;

• Histologically confirmed FIGO(International Federation of Gynecology and Obstetrics ) III/IV ovarian cancer, fallopian tube cancer, or primary peritoneal cancer; Participants must have high-grade serous or endometrioid histology;

• Platinum-sensitive recurrent ovarian cancer patients treated with olaparib as maintenance therapy according to NCCN(National Comprehensive Cancer Network) guideline and then suffered dose reduction due to adverse events. The reduction standard of olaparib following its instructions. Platinum-sensitive recurrent ovarian cancer is defined that patients are response to platinum-based chemotherapy and their platinum-free interval is greater than or equal to 6 months.

• Subjects have enough organ function: (1) Blood routine(without blood transfusion or hematopoietic stimulating factor within 7 days before screening): a.Hemoglobin(HB)≥90g/L; b.absolute neutrophil count(ANC)≥1.5*10^9/L; c.Platelet (PLT)≥80*10^9/L; (2) Blood biochemical examination(without blood or albumin transfusion within 7 days before screening): a. ALT( Alanine aminotransferase) and AST(Aspartate aminotransferase)≤2.5 times the upper limit of normal value and ALT (AST≤5 times the upper limit of normal value when liver/bone metastasis); b. total bilirubin≤1.5 times the upper limit of normal value; c.serum creatinine≤1.5 times the upper limit of normal value or creatinine clearance≥60ml/min; (3)Blood coagulation function: a. APTT(activated partial thromboplastin time ), INR(international normalized ratio) and PT≤1.5 times the upper limit of normal value; b.Doppler echocardiographic evaluation: left ventricular ejection fraction(LVEF)≥50%;

• Women of child-bearing age should have negative results of serum or urine pregnancy test within 7 days before recruited and must not be in lactation. Women are willing to adopt the appropriate methods of contraception during the trial and 6 months after last administration.
