About this study
Gastric cancer with peritoneal carcinomatosis has a poor prognosis, with little treatment options available. The current treatment strategy consists of palliative systemic chemotherapy. However, previous research suggests that systemic chemotherapy is less effective against peritoneal carcinomatosis than against metastases that spread hematogenously.
Several studies suggested that in patients with peritoneal carcinomatosis, intraperitoneal chemotherapy (IP) may be superior compared to intravenous chemotherapy. Intraperitoneal chemotherapy could lead to higher concentrations of chemotherapy in the peritoneal cavity for a longer period of time, resulting in an increased cumulative exposure to the peritoneal metastases. A few Asian studies have shown promising results with intraperitoneal chemotherapy in patients with peritoneal carcinomatosis of gastric origin. However, intraperitoneal chemotherapy combined with systemic chemotherapy has not been investigated in Western patients with peritoneal carcinomatosis of gastric origin yet. The objective of this trial is to establish the maximum tolerated dose (MTD) of intraperitoneal administration of irinotecan, added to systemic capecitabine/oxaliplatin (CAPOX) in patients with peritoneal carcinomatosis of gastric origin.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum-tolerated dose
The maximum tolerable dose and recommended phase II dose of intraperitoneal irinotecan added to systemic chemotherapy (capecitabine/oxaliplatin)
Measured: 18 weeks
Secondary outcomes (2)
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0
Toxicity graded according to the CTCAE v.5.0 determined at every cycle by the medical oncologist. Toxicity will be summarized descriptively.
Measured: 18 weeks
Area Under the Curve (AUC) ratio intraperitoneal/systemic irinotecan
During the first irinotecan intraperitoneal cycle, pharmacokinetic measurements wil be obtained. These will be withdrawn at specific time-points, namely prior to infusion, at the end of the intraperitoneal infusion, ass well as 30 minutes, 1, 1.5, 2, 3, 4, 6, and 24 hours post infusion. Blood samples from a peripheral venous catheter and peritoneal fluid will be drawn from the peritoneal access port. We assume that the AUC of irinotecan and SN-38 follow a log-normal distribution. Therefore, the analysis will be performed on log-transformed data. The antilog will be taken from the ratio and corresponding 95% confidence interval boundaries will be reported.
Measured: 3 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Irinotecan and CAPOX in people with Gastric Cancer and Peritoneal Metastases, run by Erasmus Medical Center at 2 sites in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum-tolerated dose (time frame: 18 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2025.
