Spots Global Cancer Trial Database for Ropidoxuridine and Whole Brain Radiation Therapy in Treating Patients With Brain Metastases

Study Description

Brief Summary: This phase I trial studies the side effects and best dose of ropidoxuridine when given together with whole brain radiation therapy in treating patients with cancer that has spread to the brain (brain metastases). Ropidoxuridine may help whole brain radiation therapy work better by making cancer cells more sensitive to the radiation therapy.

Detailed Description: PRIMARY OBJECTIVE: I. To conduct a phase 1 dose escalation trial in patients with brain metastases to determine the recommended phase -2 dose 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. SECONDARY OBJECTIVES: 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: Va. Delayed-recall through Hopkins Verbal Learning Test Revised (HVLT-R). Vb. Quality of life as measured by the Functional Assessment of Cancer Therapy-Brain (FACT-BR). CORRELATIVE OBJECTIVES: 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 following: Ia. %IUdR-DNA tumor cell incorporation from day 8 extracranial tumor biopsies in brain metastasis cancer patients receiving RP2D doses of IPdR as an exploratory biomarker of tumor radiosensitization using Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Ib. %IUdR-DNA cellular incorporation in patients' circulating granulocytes taken weekly during the 28-day IPdR RP2D 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 in the absence of disease progression or unacceptable toxicity. 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.
