I. To conduct a phase 1 dose escalation trial in patients with brain metastases to determine the maximum tolerated dose (MTD) of ropidoxuridine (5-iodo-2-pyrimidinone-2'-deoxyribose [IPdR]) when administered alone orally once daily for 7 consecutive days and then concurrently with conventionally fractionated whole brain radiation therapy (WBRT) for additional 21 days.
I. To observe and record anti-tumor activity to IPdR-mediated radiosensitization.
II. To estimate 6 month intracranial progression-free survival (PFS) in brain metastasis cancer patients who receive daily oral IPdR x 28 days and WBRT.
III. To establish the pharmacokinetics of daily oral dosing of IPdR times 8 days.
IV. To evaluate safety and tolerability of oral IPdR x 28 days and WBRT. V. To estimate the incidence of delayed neurological toxicity at 2, 4, and 6 months (+/-1 week) post-completion of WBRT (for patients without intracranial progression) including delayed-recall through Hopkins Verbal Learning Test Revised (HVLT-R) and quality of life as measured by the Functional Assessment of Cancer Therapy-Brain (FACT-BR).
I. To assess for biochemical evidence of IPdR effect in normal tissues (circulating granulocytes) by measuring %IUdR-deoxyribonucleic acid (DNA) cellular incorporation by flow cytometry and high-pressure liquid chromatography (HPLC) analyses as an exploratory biomarker for the %IUdR-DNA tumor cell incorporation from day 8 extracranial tumor biopsies in brain metastasis cancer patients receiving MTD doses of IPdR as an exploratory biomarker of tumor radiosensitization using Response Evaluation Criteria in Solid Tumors (RECIST) criteria.
II. To assess for biochemical evidence of IPdR effect in normal tissues (circulating granulocytes) by measuring %IUdR-deoxyribonucleic acid (DNA) cellular incorporation by flow cytometry and high-pressure liquid chromatography (HPLC) analyses as an exploratory biomarker for 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 serial complete blood count (CBC)/differential values.
OUTLINE: This is a dose escalation study of ropidoxuridine.
Patients receive ropidoxuridine orally (PO) once daily (QD) on days 1-28 and undergo WBRT daily for not more than 5 days per week beginning on day 8 for a total of 15 fractions.
After completion of study treatment, patients are followed up every 2 months for 6 months, every 3-4 months for 6 months, and every 6 months for 1 year.

- Maximum tolerated dose of ropidoxuridine defined as the dose immediately below the lowest dose that produces dose limiting toxicities in at least 2 patients assessed by National Cancer Institute's Common Toxicity Criteria version 4 [ Time Frame: Up to week 8 ]
- Tumor response assessed by Response Evaluation Criteria in Solid Tumors 1.1 [ Time Frame: Up to 2 years ]Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease in this patient population (overall and by tumor group).
- Pharmacokinetic parameters of daily oral dosing of ropidoxuridine [ Time Frame: Pre-dose, 30, 60, 120, 240 minutes and 24 hours following oral dose administration on day 1 of course 1; pre-dose, 30, 60, 120, and 240 minutes following oral dose administration on days 15 and 22 of course 1 ]The pharmacokinetics of daily oral dosing of ropidoxuridine for 28 days will be explored.
- Biomarkers [ Time Frame: Up to week 8 ]Biomarker data will be explored in a simple descriptive manner.
- Intracranial progression free survival (icPFS) [ Time Frame: From the date of start of treatment to time of progression or death, whichever occurs first, assessed at 6 months ]This will be explored using the Kaplan-Meier method. The icPFS estimates at 6 months with their standard error of the estimate will be reported.
- Overall survival [ Time Frame: Up to 2 years ]Will be explored using the Kaplan-Meier method.
- Incidence of delayed neurological toxicity including delayed-recall assessed by Hopkins Verbal Learning Test Revised (HVLT-R) and quality of life assessed by Functional Assessment of Cancer Therapy-Brain (FACT-BR) [ Time Frame: Up to 6 months ]
