Common adverse effects of treatment with quizartinib (observed in more than 20% of patients) included QT prolongation (26%), a heart complication associated with some medications and managed by reducing dosage, as well as nausea (38%), vomiting (26%), anemia (29%), fever (25%), diarrhea (20%), and fatigue (20%). These results demonstrate that quizartinib can produce a high treatment response rate in a group of very poor-prognosis AML patients with the FLT3-ITD mutation with manageable toxicity.
"Quizartinib is the first and only single-agent drug that has produced a clinical benefit in AML patients with this deadly mutation who have failed previous therapy," said Dr. Levis. "The number of patients bridged to a stem cell transplant was very significant. We plan on using these encouraging results to design and conduct additional randomized trials that will hopefully lead to the approval of quizartinib to make it accessible to those patients who previously had no hope for a cure."
Dr. Levis will present this study in an oral presentation on Monday, December 10, at 4:30 p.m. EST at the Georgia World Congress Center in Room A101, Level 1, Building A.
