People with two types of leukemia now have a new treatment option when other therapies fail. The US Food and Drug Administration has approved Sprycel (dasatinib) for people with chronic myeloid leukemia (CML) who are resistant to Gleevec (imatinib) or can't tolerate the drug, and for people with Philadelphia chromosome-positive acute lymphocytic leukemia (ALL) who are no longer being helped by their treatment.
Sprycel is made by Bristol-Myers-Squibb. The company said it should be available throughout the US within a few days. It comes as a tablet patients take twice a day.
CML is a fairly uncommon disease in the US. It is expected to strike about 4,500 people in 2006 and kill about 600. The pill Gleevec is very effective for CML and has helped many people live longer with this disease. However, some people cannot tolerate the drug, and others eventually develop resistance to it.
ALL is also uncommon. About 3,930 new cases and 1,490 deaths are expected in the US in 2006. Philadelphia chromosome-positive ALL is a more serious form of the disease, and people who have it typically develop treatment resistance sooner.
Now, people in these situations have another treatment they can try. Sprycel is a targeted therapy that works by blocking the activity of proteins that cause leukemia cells to grow.
Survival Benefit Unknown
In clinical trials of more than 400 people who could no longer take Gleevec, about 45% of people with early stages of CML had a response to the drug, meaning they had either no detectable leukemia cells in their blood after treatment, or a significant reduction in the number of leukemia cells. For people with more advanced CML and with ALL, the response rates ranged from 31% to 59%, the FDA said.
However, it is not yet known whether Sprycel helps patients live longer. Studies are under way to find out if it does.
Side effects from Sprycel may include fluid retention, bleeding, diarrhea, skin rashes, infections, headaches, fatigue, and nausea. It can also cause anemia, low white blood cell counts, and low platelet counts. Pregnant women should not take the drug because it can harm the fetus, and patients who are sexually active should use contraception while on Sprycel, Bristol-Myers-Squibb said.
