5-Fluoro-2'-Deoxcyctidine & Tetrahydrouridine to Treat Patients With

Status Completed

Clinical Trial Summary

This phase I trial studies the side effects and best dose of 5-fluoro-2-deoxycytidine when given together with tetrahydrouridine in treating patients with solid tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced). Drugs used in chemotherapy, such as 5-fluoro-2-deoxycytidine and tetrahydrouridine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of 5-fluoro-2'-deoxycytidine (5-fluoro-2-deoxycytidine) (FdCyd) administered by intravenous (IV) infusion over three hours with concomitant infusion of 350 mg/m2 of tetrahydrouridine (THU).

II. To describe the toxicities of FdCyd co-infused with THU.

III. To obtain preliminary evidence of anti-tumor activity in patients treated with this combination.

IV. To evaluate the pharmacokinetics of FdCyd and THU when co-infused.

V. To evaluate the oral bioavailability of FdCyd when co-administered with THU.

VI. When feasible, to measure the relative levels of the messenger ribonucleic acid (mRNA)'s for thymidylate synthase, deoxycytidine kinase, deoxycytidylate (dCMP) deaminase and other relevant enzymes; and the methylation status of p16 and other genes relevant to neoplasia.

OUTLINE: This is a dose-escalation study of 5-fluoro-2-deoxycytidine. Patients receive tetrahydrouridine orally (PO) on day 1; 5-fluoro-2-deoxycytidine PO on days 1 and 8; tetrahydrouridine IV over 3 hours on days 2-5, 8, and 9-12; and 5-fluoro-2-deoxycytidine IV over 3 hours on days 2-5 and 9-12 of course 1. For all subsequent courses, patients receive tetrahydrouridine IV over 3 hours and 5-fluoro-2-deoxycytidine IV over 3 hours on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
