Why This Trial Is Important

Acute myeloid leukemia (AML) is the most common type of leukemia in American adults. This disease typically strikes older adults, a group that may be less able to tolerate the aggressive therapies that are currently used to treat AML, such as combination chemotherapy and stem cell transplantation. Consequently, doctors are searching for new treatment approaches for older patients with AML.

In this study, researchers are testing a new drug called tipifarnib (Zarnestra™) to treat patients aged 70 or older who have AML and who are not eligible for standard treatment. Tipifarnib belongs to a class of drugs called farnesyltransferase inhibitors, which inhibit the biochemical signals that tell cancer cells to grow.

"In a previous clinical trial, about 20 percent of AML patients treated with tipifarnib achieved a complete response, and an additional 15 percent achieved partial response," said Dr. Erba. "Those who responded to tipifarnib experienced better survival rates."

"Tipifarnib has several advantages over standard treatments. It is administered orally, which allows patients to be treated in an outpatient setting, and it is generally well tolerated," added Dr. Erba. "We believe that this study represents a novel approach to treating AML in patients who are not eligible for or cannot tolerate standard treatments."
