PHASE3 · GOG Foundation · NCT05659381

This study is testing if a heated chemotherapy treatment followed by a drug called Niraparib can help people with advanced ovarian cancer do better after surgery compared to regular chemotherapy.

What this trial studies

This clinical trial investigates the effectiveness of heated intraperitoneal chemotherapy (HIPEC) using cisplatin, followed by Niraparib, in patients with advanced ovarian, primary peritoneal, and fallopian tube cancers. Patients will first undergo neoadjuvant chemotherapy before being randomized to receive either HIPEC or standard postoperative chemotherapy after interval cytoreductive surgery. The study aims to determine if HIPEC improves outcomes compared to surgery alone in patients with no gross residual disease after surgery.

Who should consider this trial

Good fit: Ideal candidates include patients with high grade serous or endometrioid epithelial ovarian, fallopian tube, or primary peritoneal carcinoma at stage III or IV who are eligible for neoadjuvant chemotherapy and interval cytoreductive surgery.

Not a fit: Patients with progressive disease during neoadjuvant chemotherapy or those with gross residual disease greater than 1.0 cm after surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve survival rates and quality of life for patients with advanced ovarian cancer.

How similar studies have performed: Previous studies have shown promising results with HIPEC in similar patient populations, suggesting potential for success in this approach.

Eligibility criteria

Show full inclusion / exclusion criteria 
Inclusion Criteria:

1. Patients must have a pathologic diagnosis of high grade serous or endometroid epithelial ovarian, fallopian tube, or primary peritoneal carcinoma, FIGO stage III or IV documented on CT scan/MRI, must be recommended and agree to undergo platinum-based neoadjuvant chemotherapy with or without physician choice bevacizumab (3-4 cycles allowed, with bevacizumab held for at least 28 days preoperatively) and are considered candidates for (and planned to have) interval cytoreductive surgery (iCRS) followed by chemotherapy and niraparib maintenance as determined by the enrolling investigator. Patients may continue bevacizumab after a minimum of 28 days post iCRS and during niraparib maintenance per local standard.
2. Patients with stage IV disease must have complete response of extra-abdominal disease on preoperative imaging (e.g. pleural effusion, mediastinal, inguinal, supraclavicular lymphadenopathy, or other extra-abdominal metastases) or be deemed resectable with iCRS.
3. Patients must have HRD/LOH positive tumors. Patients with germline or somatic BRCA or other similar mutations (RAD51C, RAD51D, BRIP1, BARD) are not required to have HRD/LOH testing. Patients without BRCA or germline mutations must have HRD/LOH testing using Myriad myChoice®/Foundation Medicine/Caris Life Sciences platforms. HRD test results must be available prior to registration to meet entry criteria.
4. Patients must have R0 (no gross/visible residual disease) or R1 (gross/visible residual disease ≤ 1.0 cm in the longest diameter) following iCRS and prior to randomization.
5. Patient must have adequate bone marrow and organ function:

   Bone marrow function:

   Hemoglobin ≥ 8.5 g/dL. Absolute neutrophil count (ANC) ≥ 1,500/mm3. Platelets ≥ 100,000/mm3.

   Renal function:

   Creatinine ≤ 1.3mg/dl OR Calculated creatinine clearance (≥ 30 mL/min/1.73 m2) per National Kidney Foundation guidelines and NHANES III

   Hepatic function:

   Bilirubin ≤ 1.5 times ULN. ALT ≤ 3 times the ULN. AST ≤ 3 times the ULN.

   Neurologic function:

   Peripheral neuropathy ≤ CTC AE grade 2.
6. Patients must have an ECOG performance status of 0 or 1.
7. Patient must be age \> 18.
8. Patients must have a life expectancy \> 3 months.
9. Patients of childbearing potential must have a negative serum pregnancy test within 28 days prior to iCRS and must be practicing an effective form of contraception (with failure rate \<1% per year) during the study period and for 6 months following the last dose of niraparib. Patients of childbearing potential must consent to pregnancy testing prior to receiving niraparib and monthly thereafter for the duration of the study.

   Patients are considered postmenopausal and not of child-bearing potential if they are free from menses for \>1 year or surgically sterilized.
10. Patients must have normal blood pressure (BP) or adequately treated and controlled hypertension based on local standard of care (systolic BP ≤ 140 mmHg and diastolic ≤ 90 mmHg) prior to starting niraparib.
11. Patients receiving corticosteroids may continue as long as their dose is stable for at least 4 weeks prior to randomization.
12. Patients must agree to not donate blood during the study or for 90 days after the last dose of study treatment.
13. Patients with known human immunodeficiency virus (HIV) are allowed if they meet all the following criteria:

    1. Cluster of differentiation 4 ≥350/µL and viral load \<400 copies/mL
    2. No history of acquired immunodeficiency syndrome-defining opportunistic infections within 12 months prior to enrollment
    3. No history of HIV associated malignancy for the past 5 years
    4. Concurrent antiretroviral therapy as per the most current National Institutes of Health (NIH) Guidelines for the Use of Antiretroviral Agents in Adults and Adolescents Living with HIV started \>4 weeks prior to study enrollment

4. Patients not eligible for iCRS based on evidence of progression of disease during neoadjuvant chemotherapy (documented on CT scan/MRI required within 35 days of iCRS).
5. Patients not eligible for iCRS based on medical co-morbidities as per the enrolling investigator.
6. Patients with stage IV disease without complete response of extra-abdominal disease on preoperative findings (e.g., pleural effusion, mediastinal, inguinal, supraclavicular lymphadenopathy, mesemchymal liver metastases or other extra-abdominal metastases) who are not deemed resectable with iCRS.
