ClinConnect Summary

This clinical trial is studying a new treatment approach for women with ovarian cancer that no longer responds well to platinum-based chemotherapy, which is a common type of cancer treatment. The study combines four medicines—Etoposide capsules, Bevacizumab, Iparomlimab, and Tuvonralimab—to see if this combination is safe and effective in slowing down the cancer, shrinking tumors, and helping patients live longer. Researchers will carefully watch how well the treatment works, how long it keeps the cancer from growing, and any side effects that may occur.

Women between 18 and 75 years old with a specific type of ovarian cancer that has either stopped responding or quickly returned after platinum chemotherapy might be eligible. To join, participants need to have measurable tumors that doctors can track and must be in good overall health with adequate blood counts and organ function. Those who have had between one and six previous cancer treatments, including at least one platinum-based chemotherapy, may qualify. During the study, participants will receive the combination treatment and be closely monitored for safety and response. It’s important to note that the trial is not yet open for enrollment, and women who are pregnant, breastfeeding, or have other serious health issues may not be eligible. The goal is to find better treatment options for women facing this challenging form of ovarian cancer.

Eligibility criteria

• Inclusion Criteria:
• • 1. Age: 18-75, female;
• • 2. According to RECIST 1.1 criteria, there are measurable lesions at baseline;
• • 3. ECOG PS： 0-1；
• • 4. Epithelial ovarian, fallopian tube, and primary peritoneal cancer with platinum resistance or platinum refractory recurrence; Provide 10 white films for pathological type confirmation and efficacy marker exploration, and meet all of the following conditions.
• • ① Received systemic treatment with ≥ 1 line and ≤ 6 lines, among which only received systemic treatment with ≤ 4 lines after platinum resistance relapse.
• ② Previous treatments should include at least one platinum based chemotherapy regimen. There are two specific situations:
• • 1. For patients who have only received 1-line platinum based chemotherapy in the past, disease remission (CR or PR) must be achieved, and disease progression must occur within a period of ≥ 4 weeks and\<6 months after the last platinum based chemotherapy.
• • 2. For patients who have received systemic treatment from line 2 to line 5 in the past, it is required that disease progression must occur within a period of less than 6 months after the last platinum based chemotherapy.
• Note: When determining the number of lines, the following requirements should be noted:
• • The overall count of neoadjuvant ± adjuvant systemic therapy is one line. Maintenance treatment does not calculate the number of lines separately. Simple endocrine therapy is counted as a baseline, but the use of endocrine therapy due to non disease progression (such as only elevated CA-125) is not counted as a baseline.
• • Changing the treatment plan due to intolerance without disease progression is not considered as changing the line.
• • The subject needs to experience disease progression after the final systemic treatment.
• 5. The main organ functions well and meets the following criteria:
• • 1. Blood routine examination (without blood transfusion or correction with hematopoietic stimulating factor drugs within 14 days): hemoglobin (Hb) ≥ 90g/L; Absolute neutrophil count (ANC) ≥ 1.5 × 109/L; platelet count (PLT) ≥ 90 × 109/L;
• • 2. Biochemical examination: alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN (≤ 5 × ULN for tumor liver metastases); Serum total bilirubin (TBIL) ≤ 1.5 × ULN (Gilbert syndrome subjects, ≤ 3 × ULN); Serum creatinine (Cr) ≤ 1.5 × ULN, or creatinine clearance rate ≥ 60mL/min;
• • 3. Coagulation function: activated partial thromboplastin time (APTT), international normalized ratio (INR), prothrombin time (PT) ≤ 1.5 × ULN;
• • 4. Urine routine examination shows urinary protein\<2+; If urinary protein is ≥ 2+, 24-hour urinary protein quantification should be\<1 g;
• • 5. Doppler ultrasound evaluation: left ventricular ejection fraction (LVEF) ≥ 50%.
• • 6. Non surgical sterilization or female patients of childbearing age are required to use two medically approved contraceptive measures (such as intrauterine devices, birth control pills, or condoms) during the study treatment period and within 3 months after the end of the study treatment period; Female patients of childbearing age who undergo non-surgical sterilization must have a negative serum HCG test within 72 hours before their first medication and must be non lactating; For male patients whose partners are women of childbearing age, two effective methods of contraception should be used during the study treatment period and within 3 months after the end of the study treatment period.
• • 7. The subjects voluntarily joined this study, signed informed consent forms, had good compliance, and cooperated with follow-up.
• Exclusion Criteria:
• • 1. Patients who participate in other clinical trials simultaneously;
• • 2. Allergic constitution, including a history of severe drug allergies or drug allergic reactions; Known to be allergic or intolerant to the investigational drug;
• • 3. No measurable lesions or lesions that cannot be evaluated;
• • 4. Patients with untreated central nervous system metastases, who have previously received systemic or curative treatment for brain or meningeal metastases (radiotherapy or surgery), have been confirmed stable for at least one month by imaging, and have stopped systemic hormone therapy (dose\>10mg/day prednisone or other therapeutic hormones) for more than two weeks without clinical symptoms can be included;
• • 5. Those who are unable to swallow pills normally or have gastrointestinal dysfunction, as determined by researchers, may affect drug absorption;
• • 6. Individuals who have experienced intestinal obstruction within the past 3 months;
• • 7. At present, there are uncontrollable malignant pleural effusion, ascites, or pericardial effusion (defined as those that cannot be effectively controlled by diuretics or puncture methods as determined by researchers);
• • 8. Suffering from uncontrolled comorbidities, including but not limited to: active HBV or HCV infection; Known history of HIV infection or AIDS; Active syphilis; Active tuberculosis; Active infection; Uncontrolled hypertension and symptomatic heart failure; Active bleeding;
• • 9. History of myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML) or other malignant tumors within 5 years prior to the initial administration of the study (excluding completely relieved carcinoma in situ and malignant tumors with slow progression determined by the investigator)
• • 10. Other incurable malignant tumors in the past (within 5 years) or at the same time, except for cured skin basal cell carcinoma, cervical carcinoma in situ and breast cancer with no recurrence after radical surgery\>3 years;
• • 11. Pregnant or lactating women;
• • 12. According to the researchers' assessment, there may be other factors that could lead to the forced termination of this study, such as other serious illnesses (including mental illnesses) requiring concurrent treatment, serious laboratory abnormalities, and family or social factors that could affect the safety of the subjects or the collection of data and samples.
