New drug combo shows promise for resistant ovarian cancer
NCT ID NCT05494580
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a combination of two drugs, pamiparib and surufatinib, in 29 women with ovarian cancer that stopped responding to platinum chemotherapy and had previously taken PARP inhibitors. The goal was to see if the combo could control the cancer for at least 6 months. The approach targets cancer cells and their blood supply, but it is not a cure.

Inclusion Criteria: 1. Signed Informed Consent Form; 2. Histologically confirmed epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer; 3. Platinum-resistant disease, defined as progression within 6 months from completion of most recent platinum-containing therapy. Subject may have been treated with additional regimen(s) subsequent to determination of platinum resistance; 4. Patients must have received one prior PARP inhibitor therapy, and there must be a ≥ 6 month interval since treatment; 5. Female participants age 18-75 years; 6. Has measurable lesion per RECIST v1.1; 7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; 8. Life expectancy ≥ 3 months; 9. Patients must have normal organ and bone marrow function; 10. Women of childbearing potential should have a negative serum or urine pregnancy test prior to receiving the first dose of study treatment; and should be willing to use one acceptable contraception (i.e., oral contraceptives, condoms, intrauterine devices \[IUDs\]) throughout the period of taking study treatment and for at least 6 months after the last dose of study drug(s). Exclusion Criteria: 1. Histological diagnosis of mucinous adenocarcinoma; 2. Has received prior therapy with small molecule antiangiogenic receptor tyrosine kinase inhibitors (TKIs); 3. Known or suspected allergy to any of study drugs; 4. Has clinically significant cardiovascular disease within 6 months from first dose of study intervention, including New York heart association \[NYHA\] class \> 2, unstable angina, myocardial infarction, cardiac arrhythmia associated with hemodynamic instability (including corrected QT (QTc) interval ≥ 450 ms in men, ≥ 470 ms in female); 5. Has active ulcers, gastrointestinal perforation or obstruction; 6. Active bleeding or pathologic condition that carries a high risk of bleeding; 7. Inadequately controlled hypertension (systolic blood pressure ≥ 150 mmHg and/or diastolic blood pressure ≥ 90 mmHg) with or without treatment; 8. Major surgery within 28 days of starting study treatment; 9. Proteinuria ≥ (++) or 24 hours total urine protein \> 1.0 g; 10. Uncontrolled pericardial or pleural or peritoneal effusions; 11. Has a diagnosed and/or treated additional malignancy within the last 5 years. Exceptions include in situ cervical cancer, non-melanoma skin cancer, or superficial bladder tumors that has undergone potentially curative therapy; 12. Known Human Immunodeficiency Virus (HIV) infection; 13. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis; 14. Any medical or other condition that in the opinion of the investigator(s) would preclude the participant's participation in the study.
