Iclusig Clinical Drug Trials

Iclusig Linked to  Blood Clots and Heart Damage

Thomas J. Henry Attorneys is currently investigating reports of life-threatening side effects associated with Ariad Pharmaceutical’s cancer drug Iclusig. The U.S. Food and Drug Administration halted clinical trials for Iclusig after receiving reports that some patients in the clinical trials had suffered from adverse events including heart damage and blood clots.


  • Iclusig (ponatinib) received FDA approval in December to be used as a treatment of two rare blood cancers – acute lymphoblastic leukemia (ALL) and chronic myeloid leukemia (CML).
  • Upon reaching the market, the drug carried a label warning of liver toxicity, blood clots, and hypertension.
  • The drug was approved by the FDA in December based on an accelerated approval program which relied on a single study showing that patients responded to treatment.
  • New data submitted to the FDA shows at least 20 percent of patients treated with Iclusig developed blood clots or narrowing of blood vessels.
  • Iclusig was being tested in seven mid-stage clinical trials as a possible treatment for lung cancer, thyroid cancer, and another blood cancer.
  • According to an Ariad news release and as published in Reuters, the suspension of these trials was in response to adverse events including blood clots in 12 percent of patients and heart damage in 6.2 percent of patients.
