About this study

Official title: Phase I and Pharmacology Study of Oral 5-Iodo-2-Pyrimidinone-2'- Deoxyribose (IPdR) as a Prodrug for IUdR-Mediated Tumor Radiosensitization in Gastrointestinal Cancers

This phase I trial studies the side effects and best dose of ropidoxuridine in treating patients with gastrointestinal cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment undergoing radiation therapy. Ropidoxuridine may help radiation therapy work better by making tumor cells more sensitive to the radiation therapy.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To conduct a phase I dose escalation trial, to determine the safety and the maximum tolerated dose (MTD), of oral (po) IPdR (ropidoxuridine) given daily for 28 consecutive days with concurrent intensity-modulated radiation therapy (IMRT) in patients with advanced gastrointestinal cancers treated with palliative radiation.

SECONDARY OBJECTIVES:

  1. To observe and record anti-tumor activity. II. To establish the pharmacokinetics of daily po dosing of IPdR x 28 days. III. To assess, for patients treated at the MTD, for biochemical evidence of IPdR effect in normal tissue (circulating granulocytes) and tumor tissue (in patients with accessible tumor tissue) by measuring %iododeoxyuridine (IUdR)-deoxyribonucleic acid (DNA) cellular incorporation by flow cytometry and high-pressure liquid chromatography (HPLC) analyses.

IV. To assess the use of %IUdR-DNA cellular incorporation (measured by the investigational laboratory assays of flow cytometry and HPLC) as an exploratory biomarker of IPdR for the following effects: the %IUdR-DNA tumor cell incorporation from day 8 tumor biopsies in gastrointestinal (GI) cancer patients receiving MTD doses of IPdR as an exploratory biomarker of tumor radiosensitization using Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

  1. To assess the use of %IUdR-DNA cellular incorporation (measured by the investigational laboratory assays of flow cytometry and HPLC) as an exploratory biomarker of IPdR for the following effects: the %IUdR-DNA cellular incorporation in patients' circulating granulocytes taken weekly during the 28-day IPdR MTD dose, on day 29, and week 8 as an exploratory biomarker of IPdR systemic toxicities to bone marrow as measured by complete blood count (CBC)/differential values.

OUTLINE: This is a dose-escalation study of ropidoxuridine.

Beginning 30 minutes to 2 hours before radiation therapy, patients receive ropidoxuridine PO once daily (QD) on days 1-28 in the absence of disease progression or unacceptable toxicity. Beginning on day 8, patients undergo IMRT 5 days a week for 3 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 4 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum tolerated dose (MTD) defined as the dose below which 2 or more of 6 patients experience dose-limiting toxicity

    Measured: Up to 28 days

Secondary outcomes (5)
  1. %iododeoxyuridine (IUdR)-deoxyribonucleic acid (DNA) incorporation in tumor biopsies

    Correlate %IUdR-DNA incorporation in human gastrointestinal (GI) tumor biopsies in the proposed phase I and pharmacokinetic (PK) clinical trial in GI cancer patients receiving palliative abdominal and/or pelvic radiation therapy (RT) by linear regression.

    Measured: Up to 2 weeks

  2. Pharmacokinetic (PK) incorporation in tumor biopsies

    Correlate %IUdR-DNA incorporation in human GI tumor biopsies in the proposed phase I and PK clinical trial in GI cancer patients receiving palliative abdominal and/or pelvic RT by linear regression.

    Measured: Days 1, 15 and 22 before drug administration, at 30, 60, 120, and 240 minutes (and 24 hours on day 1 only) following drug administration

  3. %iododeoxyuridine (IUdR)-deoxyribonucleic acid (DNA) incorporation in peripheral (circulating) granulocytes

    Correlate %IUdR-DNA incorporation in human GI tumor biopsies in the proposed phase I and PK clinical trial in GI cancer patients receiving palliative abdominal and/or pelvic RT by linear regression.

    Measured: Up to 4 weeks after completion of study treatment

  4. Pharmacokinetic (PK) incorporation in peripheral (circulating) granulocytes

    Correlate %IUdR-DNA incorporation in human GI tumor biopsies in the proposed phase I and PK clinical trial in GI cancer patients receiving palliative abdominal and/or pelvic RT by linear regression.

    Measured: Days 1, 15 and 22 before drug administration, 30, 60, 120, and 240 minutes (and 24 hours on day 1 only) following drug administration

  5. Tumor response relationship to the %iododeoxyuridine (IUdR)-deoxyribonucleic acid (DNA) incorporation using Response Evaluation Criteria in Solid Tumors (RECIST) criteria based on high-pressure liquid chromatography (HPLC) and flow cytometry measurements

    Tumor response is the dependent variable and can be binomial (i.e. response versus [vs.] no response) or multinomial (i.e. complete response, partial response, stable disease or progressive disease) and the %IUdR-DNA incorporation is the independent variable.

    Measured: Day 8
