Clinical Trial Summary

Single center, open label, phase I-II, non-randomized, two-cohort, repeated single dose study to explore the feasibility, efficacy, safety, and Overall Response Rate (ORR) of oxaliplatin, or cisplatin and doxorubicin when given as a pressurized intraperitoneal chemotherapy (PIPAC) to patients (men and women) with peritoneal carcinomatosis from ovarian, gastric and colorectal cancers and in primary cancers of peritoneum.

Intervention

Drug:
• Pressurized IntraPeritoneal Air-flow Chemotherapy (PIPAC) fixed repeated dose
An open access with a midline 5-6 cm incision is performed and a single-port platform is positioned. A 12 mm Hg CO2 pneumoperitoneum is inflated. PC extent is evaluated according to Peritoneal Cancer Index (PCI) and peritoneal biopsies are taken. A nebulizer is connected to an intravenous high-pressure injector and inserted into the peritoneal cavity; the tightness of the abdomen has to be documented with a CO2 zero-flow. The laparoscopic camera and the nebulizer are maintained in position by a self-retaining retractor (Thompson). A pressurized aerosol containing drugs is delivered. Standard dosage of drugs for each PIPAC: Cisplatin (7.5 mg/m²) + Doxorubicin (1.5 mg/m²) or Oxaliplatin (92 mg/m²) The capnoperitoneum is then maintained for 30 minutes at 37°C. At the end, the aerosol is exsufflated through two sequential micro-particle filters into the air-waste system of the hospital.
• Pressurized IntraPeritoneal Air-flow Chemotherapy (PIPAC) increasing single dose
An open access with a midline 5-6 cm incision is performed and a single-port platform is positioned. A 12 mm Hg CO2 pneumoperitoneum is inflated. PC extent is evaluated according to Peritoneal Cancer Index (PCI) and peritoneal biopsies are taken. A nebulizer is connected to an intravenous high-pressure injector and inserted into the peritoneal cavity; the tightness of the abdomen has to be documented with a CO2 zero-flow. The laparoscopic camera and the nebulizer are maintained in position by a self-retaining retractor (Thompson). A pressurized aerosol containing drugs is delivered. Escalating dosage of drugs for PIPAC: Cisplatin + Doxorubicin (from 15 mg/m² + 3 mg/m² to 100 mg/m² + 30 mg/m²) or Oxaliplatin (from 92 mg/m² to 300mg/m²).The capnoperitoneum is then maintained for 30 minutes at 37°C. At the end, the aerosol is exsufflated through two sequential micro-particle filters.
