Clinical Trial Summary

The rationale of the current study is that the addition of intraperitoneal irinotecan (75 mg) to palliative systemic therapy is feasible and safe, and might result in an increased overall and progression free survival in patients with unresectable colorectal peritoneal metastases. The primary objectives are to explore the overall survival for the addition of intraperitoneal irinotecan (75 mg) to palliative systemic therapy in patients with unresectable colorectal peritoneal metastases. Secondary objectives are to assess the progression-free survival, toxicity profile, patient reported outcomes, costs, tumor response during trial treatment, and the systemic and intraperitoneal pharmacokinetics of irinotecan and SN-38. This is a single-arm, open-label, phase II study and patients will receive intraperitoneal irinotecan (75 mg) in combination with modified FOLFOX4 + bevacizumab.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall survival	calculated from (a) the interval from diagnosis of peritoneal metastases until death or last follow-up; (b) the interval from the first day of the first cycle until death or last follow-up).	3 year
Secondary	Progression-free survival	calculated from the interval from the start of trial treatment until first evidence of intraperitoneal and/or systemic disease progression, and/or start of second-line systemic therapy, or last follow-up	3 year
Secondary	Toxicity in CTCAE grading	Defined as the number of patients who experience / the total number of Common Terminology Criteria for Adverse Events (CTCAE, version 5.0) grade 3-5 adverse events, measured up to four weeks after the last cycle of intraperitoneal irinotecan (75 mg) with concomitant palliative systemic therapy. With the exception of peripheral neuropathy, which will be reported indefinitely, ranging from CTCAE grade 1-5.	28 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Toxicity measured up to four weeks after last cycle.
Secondary	Patient-reported outcomes (PROs) with EQ-5D-5L	Assessed with the 5-level EQ-5D by EuroQol group (EQ-5D-5L) at baseline, one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle. The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Measured one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle.
Secondary	Patient-reported outcomes (PROs) with EORTC QLQ-C30	Assessed with the European Organization for Research and Treatment for Cancer Quality of Life Questionnaire (EORTC QLQ-C30) at baseline, one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle. The EORTC QLQ-C30 comprises 30 items, 24 of which are aggregated into nine multi-item scales, that is, five functioning scales, three symptom scales and one global health status scale. The remaining six single-item assess symptoms. All of the scales and single-item measures range in score from 0 to 100. Higher score for the functioning scales and global health status denote a better level of functioning (i.e. a better state of the patient), while higher scores on the symptom and single-item scales indicate a higher level of symptoms (i.e. a worse state of the patient).	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Measured one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle.
Secondary	Patient-reported outcomes (PROs) with EORTC QLQ-CR29	Assessed with the European Organization for Research and Treatment for Cancer Quality of Life Questionnaire, specifically for colorectal cancer (EORTC QLQ-CR29) at baseline, one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle. The resulting QLQ-CR29 consisted of four scales and 19 individual items. Higher scores indicate a higher level of symptoms (i.e. a worse state of the patient).	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Measured one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle.
Secondary	Healthcare costs	According to the Dutch manual for cost analysis in health care research, and assessed with the iMTA Medical Consumption Questionnaire at baseline, one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle. The volumes of used healthcare costs were multiplied with the unit costs of these corresponding services.	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Measured one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle.
Secondary	Productivity loss costs.	Assessed with the iMTA Productivity Cost Questionnaire at baseline, one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle.	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Measured one week after the first cycle, one week after the fourth cycle, one week after the eighth cycle, and one week after the twelfth cycle.
Secondary	Occurrence and degree of nephrotoxicity	Assessed during standard-of-care laboratory assessment for nephrotoxicity (creatinine, eGFR, and ureum) analysis before each subsequent cycle and graded according to Common Terminology Criteria for Adverse Events (CTCAE, version 5.0).	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles.
Secondary	Occurrence and degree of hepatotoxicity	Assessed during standard-of-care laboratory assessment for hepatotoxicity (albumin, bilirubin, AST, ALT, LD, AF, yGT) analysis before each subsequent cycle and graded according to Common Terminology Criteria for Adverse Events (CTCAE, version 5.0).	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles.
Secondary	Occurrence and degree of haematological toxicity	Assessed during standard-of-care laboratory assessment for haematological toxicity (haemoglobin, leucocytes, thrombocyte) analysis before each subsequent cycle and graded according to Common Terminology Criteria for Adverse Events (CTCAE, version 5.0).	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles.
Secondary	Response of Tumor marker during treatment	Assessed by carcino-embryonic antigen (CEA) analysis during standard laboratory analysis before each subsequent cycle	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles.
Secondary	Number of patients that completed twelve cycles	To determine the number of patients completing twelve cycles of treatment with intraperitoneal irinotecan (75 mg) and concomitant palliative systemic therapy, required dose reductions, and reasons for discontinuation.	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles.
Secondary	Objective radiological response	assessed by thoracoabdominal CT at baseline, after the fourth cycle, after the eighth cycle, and after the twelfth cycle according to RECIST.	24 weeks. Each cycle is 2 weeks, maximum of 12 cycles. Measured at baseline, after the fourth cycle, after the eighth cycle, and after the twelfth cycle.
Secondary	Peritoneum/plasma ratio of intraperitoneal irinotecan	To determine the the peritoneum/plasma ratio of intraperitoneal during the first and fourth cycle of intraperitoneal irinotecan (75 mg) and concomitant palliative systemic therapy. Whole blood and peritoneal fluid will be drawn from a peripheral intravenous access and the peritoneal access port, respectively, and collected in 3 mL lithium heparin tubes and 2 mL cryotubes, respectively, at the following moments after the start of irinotecan infusion; t=0, at the end of infusion (EOI), t=30 minutes after EOI and t =2 hrs after EOI and t = 4hrs after EOI. The ratio between the Area Under the Curve (AUC) between irinotecan measured in the peritoneum and measured in the plasma is taken.	8 weeks. Each cycles is 2 weeks. Measured during cycle 1 and cycle 4.
