Tipifarnib in Treating Patients With Myelodysplastic Syndromes

Status Completed

Clinical Trial Summary

This phase I trial studies the side effects and best dose of tipifarnib in treating patients with myelodysplastic syndromes. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the toxicity profile and antitumor activity of the farnesyltransferase (FTase) inhibitor R115777 (tipifarnib) in patients with myelodysplastic syndrome (MDS) treated on a one week on/one week off schedule.

II. To determine the effect on R115777 on a one week on/one week off schedule on FTase activity, prenylation of RAS and other substrates and on downstream effects.

OUTLINE: This is a dose-escalation study.

Patients receive tipifarnib orally (PO) twice daily (BID) on weeks 1, 3, 5, and 7. Treatment repeats every 8 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. ;
