Acute Myeloid Leukemia Clinical Trial

Tipifarnib in Treating Patients With Acute Myeloid Leukemia in Remission

Summary

This randomized phase III trial studies tipifarnib in treating patients with acute myeloid leukemia (AML) in remission. Tipifarnib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. It is not yet known whether tipifarnib is more effective than observation alone in preventing the recurrence of AML.

PRIMARY OBJECTIVES:

I. To compare R115777 (tipifarnib) maintenance therapy to observation only with respect to disease-free survival (DFS) in patients with AML in second or subsequent complete remission or in complete response (CR) following primary induction failure.

SECONDARY OBJECTIVES:

I. To compare overall survival of patients in both arms. II. To evaluate the long-term safety and toxicity of extended administration of R115777 in AML patients in remission.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive tipifarnib orally (PO) twice daily (BID) on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM B: Patients undergo observation only.

After completion of study treatment, patients are followed up for 5 years.

AML by World Health Organization (WHO) criteria
Acute myeloid leukemia with multilineage dysplasia

Within 60 days of discharge from the hospital following induction therapy or
Within 60 days of discharge from the hospital following post-remission therapy or
Within 60 days of recovery of blood counts following last dose of chemotherapy

All of the patients below are eligible for study entry:

Patients who have received consolidation therapy
Patients who have not received any consolidation or post remission therapy
Patients who have had an autologous stem cell transplant
Patients who have received an allogeneic transplant (bone marrow transplant [BMT] or peripheral stem cell transplant [PSCT]) in their current remission are ineligible; patients who have had an allogeneic transplant in a previous remission and are currently in remission after subsequent relapse are eligible
Patients with a history of extramedullary disease are eligible if they are in complete remission at the time of study entry and no longer requiring therapy for their extramedullary disease
Patients must not be pregnant or breast-feeding; all females of childbearing potential must have a blood test or urine study < 2 weeks prior to randomization to rule out pregnancy
Women of childbearing potential and sexually active males are strongly advised to use an accepted and effective method of contraception
Patients must not be known to have an allergy to imidazole drugs, such as clotrimazole ketoconazole, miconazole, econazole, or terconazole; this does not include fluconazole, voriconazole, or itraconazole
Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 2
Patients must not have active cardiac or pulmonary disease; but patient will be eligible if disease is medically controlled
Patients must not have active renal disease; creatinine must be =< 1.5 x upper limit of normal
Patients must not have active hepatic disease; total or direct bilirubin must be < 2 mg/dl
Serum glutamic oxaloacetic transaminase (SGOT) (aspartate aminotransferase [AST]) and serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) must be =< 2.5 times the upper limit of normal
