Iclusig (Ponatinib): Drug Safety Communication - Increased Reports Of Serious Blood Clots In Arteries And Veins
UPDATED 10/31/2013. FDA has asked, and Ariad Pharmaceuticals has agreed, to suspend marketing and sales of Iclusig (ponatinib), a leukemia chemotherapy drug, because of the risk of life-threatening blood clots and severe narrowing of blood vessels. FDA will continue to evaluate the drug to further understand its risks and potential patient populations in which the benefits of the drug may outweigh the risks. Patients currently receiving Iclusig should discuss with their health care professionals the risks and benefits of continuing treatment with the drug.

Pharmacy, Oncology
Issue
FDA is investigating an increasing frequency of reports of serious and life-threatening blood clots and severe narrowing of blood vessels (arteries and veins) of patients taking the leukemia chemotherapy drug Iclusig (ponatinib). Data from clinical trials and postmarket adverse event reports show that serious adverse events have occurred in patients treated with Iclusig, including heart attacks resulting in death, worsening coronary artery disease, stroke, narrowing of large arteries of the brain, severe narrowing of blood vessels in the extremities, and the need for urgent surgical procedures to restore blood flow. FDA is actively working to further evaluate these adverse events and will notify the public when more information is available.
Background
Iclusig is a prescription medicine used to treat adults diagnosed with chronic phase, accelerated phase, or blast phase chronic myeloid leukemia (CML) or Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL), who are no longer benefiting from previous treatment or who did not tolerate other treatment. At the time of Iclusig’s approval in December 2012, the drug label contained information about the risks of blood clots in the Boxed Warning and Warnings and Precautions sections. In clinical trials conducted before approval, serious arterial blood clots occurred in 8 percent of Iclusig-treated patients, and blood clots in the veins occurred in 3 percent of Iclusig-treated patients. In the most recent clinical trial data submitted by the manufacturer to FDA, at least 20 percent of all participants treated with Iclusig have developed blood clots or narrowing of blood vessels.
Recommendation
Health care professionals should consider for each patient, whether the benefits of Iclusig treatment are likely to exceed the risks of treatment. Patients taking Iclusig should seek immediate medical attention if they experience symptoms suggesting a heart attack such as chest pain or pressure, pain in their arms, back, neck or jaw, or shortness of breath; or symptoms of a stroke such as numbness or weakness on one side of the body, trouble talking, severe headache, or dizziness. FDA is providing this information to patients and health care professionals while it continues its investigation.
