Primary Outcome Measures:
  • The objective is to determine the rate of complete remission or complete remission with incomplete platelet recovery induced by tipifarnib in patients with refractory or relapsed AML treated until disease progression or unacceptable toxicity occurs.

Secondary Outcome Measures:
  • These objectives are to determine the objective remission rate, duration of remission, time to disease progression/progression-free survival, overall survival, and the clinical benefit/quality of life (QOL). The safety profile will also be determined.

Enrollment: 252
Study Start Date: April 2001
Study Completion Date: July 2003
Detailed Description:
Acute myeloid leukemia (AML) accounts for approximately 25% of all cases of leukemia diagnosed in the Western hemisphere. First-line chemotherapy regimens induce complete remissions in 55-75% of patients. However, between 50% and 70% of patients who achieve remission will relapse. Current therapy for patients refractory to initial therapy or who relapse within 6 months of remission is unsatisfactory because complete remission rates are low and remission duration is brief. New drugs with novel mechanisms of action may be more beneficial than the currently available ones. Tipifarnib represents a new class of oncology drugs which have a specific cellular target (inhibition of the farnesyl transferase protein), one of the components of the Ras oncogene, as its specific mechanism of acton. It is believed that inhibition of this protein will lead to a decrease of cellular proliferation or cell death. This is an open-label, multicenter, non-comparative phase 2 study investigating the efficacy and safety of farnesyl transferase inhibition with tipifarnib administered orally as a single agent, twice daily, for the first 21 days of every 28 day cycle. Patients are enrolled by disease status into two cohorts; Cohort 1 includes patients with relapsed AML and Cohort 2, patients with refractory AML. All patients will be treated for a sufficient length of time to determine response to study medication (effectiveness) by evaluating the rate of complete remission (CR) or complete remission with incomplete platelet recovery (CRp), duration of complete remission, time to disease progression and progression-free survival, overall survival, and to characterize clinical benefit and quality of life (QOL). The safety profile of tipifarnib will also be determined in patients with refractory of relapsed AML.. The patients will receive six tablets (100 mg each) of tipifarnib twice daily for 21 of 28 day cycles (7 day rest period between cycles). Patients may receive tipifarnib until disease progression or unacceptable toxicity occurs.
