Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) Associated With Systemic Chemotherapy in Women With Advanced Ovarian Cancer

Recruiting now · Phase 1

Conditions studied: Metastatic Ovarian Carcinoma, Peritoneal Carcinomatosis, Stage III Ovarian Cancer, Stage IV Ovarian Cancer, Stage III Fallopian Tube Cancer, Stage IV Fallopian Tube Cancer, Metastatic Malignant Neoplasm in the Peritoneum

In brief

Women with a history of tumor response insufficient to allow complete cytoreductive surgery after three cycles of prior neoadjuvant systemic carboplatin-paclitaxel chemotherapy will be prospectively enrolled in this phase I study. After providing written informed consent and confirmation of unresectable disease by multidisciplinary assessment, patients will undergo three cycles of combined chemotherapy consisting of Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) with doxorubicin and cisplatin at escalating dose levels, combined with systemic intravenous chemotherapy using carboplatin and paclitaxel at standard doses. Treatment cycles will last 28 days, with PIPAC administered on Day 1 and systemic chemotherapy on Day 8, for a maximum of three cycles in the absence of unacceptable toxicity. Dose escalation of PIPAC chemotherapy will follow a Continual Reassessment Method (CRM) algorithm. The first patient will be treated at the lowest dose level, and subsequent patients will receive the recommended dose according to the CRM, conditional on the occurrence of dose-limiting toxicity (DLT) observed during Cycle 1. From dose level 7 onward, corresponding to cisplatin and doxorubicin doses associated with an increased risk of renal toxicity, sodium thiosulfate will be systematically administered prior to each PIPAC procedure for its nephroprotective effect, in accordance with the cisplatin dose level and current clinical practice. The primary objective of the study is to determine the maximum tolerated dose (MTD) of doxorubicin-cisplatin administered by PIPAC and to define the recommended dose for a subsequent phase II trial. DLTs will be actively collected and reviewed as soon as they are identified during the first treatment cycle. Secondary objectives include evaluation of pathological response, radiological tumor response, and changes in the extent of peritoneal disease following combined chemotherapy, as well as characterization of the pharmacokinetics of PIPAC-administered drugs. Additional exploratory objectives include assessment of the KELIM parameter as a predictive marker of sensitivity to combined chemotherapy and evaluation of the overall safety profile of the treatment strategy. On Day 1 of the first treatment cycle, blood samples will be collected for pharmacokinetic analysis of doxorubicin and cisplatin. Serum CA-125 levels will be measured before each intraperitoneal or intravenous chemotherapy administration throughout the study. At the end of combined chemotherapy, radiological tumor assessment by CT scan or MRI and a final CA-125 measurement will be performed. Patients achieving complete response, partial response, or stable disease according to RECIST v1.1 criteria will undergo re-evaluation for surgical resectability. If complete cytoreductive surgery is deemed feasible, surgery will be scheduled with a post-operative follow-up visit planned one month later. Patients with progressive or persistently unresectable disease will discontinue study participation.
