NCT06269978

Brief Summary

This phase I trial tests the safety, side effects, and best dose of intraperitoneal oxaliplatin and fluorouracil in treating patients with colorectal cancer that has spread to the peritoneal cavity (peritoneal metastasis). Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill cancer cells. Fluorouracil stops cells from making DNA and it may kill cancer cells. Both oxaliplatin and fluorouracil are approved by the Food and Drug Administration to treat patients with colorectal cancer, however administration of these drugs directly into the area between the muscles and organs in the abdomen (intraperitoneal) for the treatment of peritoneal metastases is experimental. Giving oxaliplatin and fluorouracil directly into the peritoneal space may be a safe and effective way of treating patients with peritoneal metastases from colorectal cancer.

Outcome Measures

Primary Outcomes (6)

  • Maximum tolerated dose (MTD)

    MTD will be determined based on isotonic regression. Specifically, the MTD will be selected as the dose for which the isotonic estimate of the toxicity rate is closest to the targeted dose limiting toxicities via Bayesian optimal interval software.

    Up to 1 year

  • Incidence of adverse events

    Adverse events (AEs) will be classified and attributed using National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 and will be summarized within and across dose levels using descriptive statistics. The overall number and percentage of patients experiencing AEs and toxicities will be summarized and reported as across all event types. All patients who have received at least one dose of the therapeutic agents will be evaluable for toxicity and tolerability.

    Up to 30 days after completion of study treatment

  • Area under the curve

    Will be computed using non-compartmental and compartmental methods. Will use graphical analyses as well as repeated measure models (linear or nonlinear mixed models, generalized estimating equations) to assess the pharmacokinetic markers in relation to clinical treatment outcomes, recognizing some inherent limitations due to sample size.

    At the end of Cycle 1 (each cycle is 28 days)

  • Clearance

    Will be computed using non-compartmental and compartmental methods. Will use graphical analyses as well as repeated measure models (linear or nonlinear mixed models, generalized estimating equations) to assess the pharmacokinetic markers in relation to clinical treatment outcomes, recognizing some inherent limitations due to sample size.

    At the end of Cycle 1 (each cycle is 28 days)

  • Volume of distribution

    Will be computed using non-compartmental and compartmental methods. Will use graphical analyses as well as repeated measure models (linear or nonlinear mixed models, generalized estimating equations) to assess the pharmacokinetic markers in relation to clinical treatment outcomes, recognizing some inherent limitations due to sample size.

    At the end of Cycle 1 (each cycle is 28 days)

  • Half-life

    Will be computed using non-compartmental and compartmental methods. Will use graphical analyses as well as repeated measure models (linear or nonlinear mixed models, generalized estimating equations) to assess the pharmacokinetic markers in relation to clinical treatment outcomes, recognizing some inherent limitations due to sample size.

    At the end of Cycle 1 (each cycle is 28 days)

Secondary Outcomes (5)

  • Tumor-cell intrinsic effects in response to IP 5FU+oxaliplatin

    Up to 16 weeks

  • Modulation of the tumor microenvironment in response to IP 5FU+oxaliplatin

    Up to 16 weeks

  • Changes in the makeup of circulating immune cells in response to IP 5FU+oxaliplatin

    Up to 16 weeks

  • Rate of conversion from unresectable to resectable

    At time of second laparoscopy, after 4 cycles of treatment (16 weeks)

  • Overall response rate

    Up to 16 weeks

Study Arms (1)

Treatment (oxaliplatin, 5FU)

EXPERIMENTAL

Patients undergo placement of indwelling IP port for chemotherapy infusion. Patients receive oxaliplatin and 5FU over 1-2 hours via IP infusion on days 1 and 15 of each cycle. Cycles repeat every 4 weeks for up to 16 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo diagnostic laparoscopy, biopsy, CT/MRI, and collection of blood samples at screening and on study and undergo collection of IP fluid samples on study.
