Phase I Trial HIPEC With Nal-irinotecan

The starting dose of nal-IRI will be 70 mg/m2 (cohort level 1) applied for 30 min using a closed HIPEC technique following completion of cytoreductive surgery. If there is dose limiting toxicity (DLT) in cohort level 1, then the dose will be reduced the dosage of the next cohort to 50 mg/m2 (cohort level 0). If there is no DLT, the dose of nal-IRI will be increased to 140 mg/m2, 210 mg/m2 and 280 mg/m2 . If one of the patients experiences DLT, then the cohort will expand to 6 patients and accrual to the current dose level and dose escalation will stop if 2 or more patients experience a DLT at a given dose level.
