phase ii study of utidelone plus fruquintinib combination therapy for platinum-resistant recurrent ovarian cancer

Conditions: Platinum Resistant Ovarian Cancer

Summary: this study is a prospective, single-arm, phase 2 clinical trial. the purpose of this study is to find out if taking utidelone capsules together with fruquintinib capsules is safe and works well for people with platinum-resistant ovarian cancer . researchers will look at the objective response rate, progression-free survival, overall survival, safety, and any side effects.

the blood or urine pregnancy test of female patients of childbearing age must be negative before enrollment. exclusion criteria: 1. it has clear cell, mucinous or sarcomatous histology, contains mixed tumors of any histological type, or low-grade/borderline ovarian cancer. 2. in platinum refractory ovarian cancer subjects, platinum refractory was defined as the best response during the first platinum containing regimen treatment as disease progression or recurrence, or disease recurrence or progress within 4 weeks after the end of platinum containing regimen treatment. 3. other malignant tumors within 5 years, excluding cured basal cell carcinoma of the skin, carcinoma in situ of the cervix and papillary carcinoma of the thyroid. 4. received nitrosourea or mitomycin c within 6 weeks before the first use of the study drug; received anti-tumor treatment within 4 weeks or 5 half lives (whichever is shorter) before the first use of the study drug, including chemotherapy, radiotherapy, biological targeted therapy, immunotherapy, etc; oral fluorouracil, small molecule targeted drugs and endocrine therapy were used 2 weeks before the first use of the study drug or within 5 half lives of the drug (whichever is shorter); traditional chinese medicine or chinese patent medicine with anti-tumor indications were used within 2 weeks before the first use of the study drug. 5. major surgical operations (craniotomy, thoracotomy or laparotomy or other operations defined by the investigator) or significant trauma were performed within 60 days before the first use of the study drug, or elective surgery was required during the trial. 6. there were patients with clinically significant skin wounds, surgical sites, wound sites, severe mucosal ulcers or fractures that were not completely healed as assessed by the researchers. 7. patients with peripheral neuropathy with ctcae 5.0 rating ≥ 2. 8. the adverse reactions of previous anti-tumor treatment have not recovered to ctcae 5.0 grade evaluation ≤ 1 (except for the toxicity without safety risk judged by researchers such as hair loss). 9. patients who have previously received eutidylon or antiangiogenic drugs (except bevacizumab). 10. urine protein detection 2+or more, or 24-hour urine protein quantitation ≥ 1.0g/24h. 11. there were symptoms or thyroid dysfunction requiring treatment at the time of screening. 12. patients with obvious evidence of bleeding tendency or medical history within 2 months before the first use of the study drug, such as black stool, hematemesis, hemoptysis, occult blood in stool++, etc. 13. subjects with active central nervous system metastasis. 14. cancerous ascites with clinical symptoms requiring puncture and drainage; or those who received drainage for the purpose of treatment within 30 days before the first use of the study drug. 15. during screening, it was found that the tumor invaded the structure of large blood vessels, such as pulmonary artery, superior vena cava or inferior vena cava, and the researchers judged that there was a high risk of bleeding; or there is a history of previously known aneurysms. 16. there was a history of arterial thrombosis or deep venous thrombosis within 6 months before the first use of the study drug; thrombosis caused by implantable venous infusion pump or catheter, or superficial venous thrombosis, except those with stable thrombosis after regular anticoagulation therapy. 17. patients with coagulation disorders, bleeding tendency, or undergoing anticoagulation therapy 2 months before the first use of the study drug. 18. have a history of serious cardiovascular and cerebrovascular diseases, including but not limited to: acute myocardial infarction, severe/unstable angina pectoris or coronary artery bypass grafting within 6 months before the first use of the study drug; the new york heart association (nyha) classification of congestive heart failure was ≥ 2; lvef\<50%； or there is a history of myocarditis (including patients who have been cured after treatment of previous myocarditis) or other grade 3 or above cardiovascular events; stroke events and/or transient cerebral ischemia occurred within 12 months before the first use of the study drug; patients with uncontrolled hypertension (systolic blood pressure ≥ 140 mmhg or diastolic blood pressure ≥ 90 mmhg) were given standard treatment; other researchers judged that there was a high risk of heart disease. 19. uncontrolled diabetic patients within 3 months before the first use of the study drug. 20. patients with active hepatitis b and/or c, i.e. hbsag positive and/or hbcab positive, detected hbv dna positive and/or anti hcv positive and hcv rna positive at the same time; human immunodeficiency virus (hiv) antibody was positive; treponema pallidum specific antibody was positive. 21. active infection or fever of unknown origin (body temperature\>38.5 ℃) before screening and first use of the study drug. 22. patients with active autoimmune diseases need systemic treatment (i.e. disease regulators, corticosteroids or immunosuppressive drugs) within 2 years before enrollment. replacement therapy (such as thyroxine, insulin or physiological corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered as a systemic treatment. 23. women who are pregnant or nursing or plan to be pregnant during the study period. 24. patients with mental disorders or poor compliance. 25. known allergic to the study drug or any of its excipients. 26. participate in another intervention clinical trial or use other research treatment at the same time. 27. the researcher believes that the subject has a serious history of systemic diseases or other reasons and is not suitable to participate in the trial.
