Why This Trial Is Important

Acute myeloid leukemia (AML) is the most common type of blood and bone marrow cancer in U.S. adults. Treatment of newly diagnosed AML usually involves chemotherapy to induce a remission of the cancer (induction therapy), followed by more chemotherapy to keep the cancer in remission and prevent a relapse (consolidation or post-remission therapy).

In this trial, researchers are trying to determine whether adding the drug oblimersen (Genasense®) to chemotherapy will improve survival in patients aged 60 and older who have previously untreated AML. Oblimersen blocks production of a protein called Bcl-2, which helps cancer cells survive. Bcl-2 is overexpressed in many types of tumors and contributes to cancer cell resistance to chemotherapy. By blocking production of Bcl-2, oblimersen may make cancer cells more susceptible to the cytotoxic effects of chemotherapy.

"Although AML long-term remission rates in younger patients are better, the long-term remission rates for AML in patients over 60 years old are very low, about 10-15 percent," said Dr. Marcucci. "AML is prevalent in the geriatric population in America, and as that population continues to grow, we can expect to see an increase in the number of older Americans with AML.

"That is why we need to come up with a new approach for treating AML in older patients," Dr. Marcucci added.

Contact Information

Patient recruitment for this trial has been stopped because early analysis indicated that the experimental treatment would not significantly improve overall survival.
