Latest & Greatest FDA Expands Eltrombopag Indication to Even Younger Pediatric Patients with ITP The U.S. Food and Drug Administration (FDA) expanded the indication for eltrombopag for the treatment of thrombocytopenia in pediatric patients one year old or older with chronic idiopathic thrombocytopenia (ITP) who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy. The updated label also includes a new oral suspension formulation designed for younger children. Eltrombopag was already approved for treating chronic ITP in children who are six years or older earlier this year, based on the results of two randomized, doubleblind, placebo-controlled trials: the phase II PETIT (Pediatric Patients with Thrombocytopenia from ITP) and the phase III PETIT2 trial. In each of these studies, the most commonly reported treatmentrelated adverse events included upper respiratory tract infection, nasopharyngitis, cough, diarrhea, pyrexia, rhinitis, abdominal pain, oropharyngeal pain, toothache, alanine aminotransferase increased, rash, aspartate aminotransferase increased, and rhinorrhea.

California State Assembly Approves Right-to-Die Bill The End of Life Operation Act, which seeks to allow terminally ill patients to end their life with the assistance of a physician, passed in California’s Senate and will now move on to Governor Jerry Brown for review. The bill allows patients who are given six months or less to live by two doctors to request to seek physician-assisted suicide, after submitting a written request and two oral requests at least 15 days apart. Patients must also possess the mental capacity to make their own health-care decision and be physically able to swallow the lethal drug combination. The bill faces criticism from religious groups and disability rights advocates who question the protection these laws afford older adults and those 24 ASH Clinical News with disabilities, as people who worry that they are a financial burden on their families could feel pressured into taking these drugs instead of pursuing more expensive, life-sustaining treatments, they argue. However, supporters note that the bill has a number of protections in place to prevent abuse of the law; for instance, the bill makes it a felony for health insurance companies to deny treatment or coverage based on whether a patients seeks these drugs. Currently in the United States, four other states have right-to-die laws, including Oregon, Vermont, Washington, and Montana. Oregon was the first state to take this step in 1994 with the passage of the Death with Dignity law.

House Passes Bill Reauthorizing Stem Cell Research On September 8, 2015, the U.S. House of Representatives passed “HR 2820: Stem Cell Therapeutic and Research Reauthorization Act of 2015,” legislation reauthorizing programs to conduct medical research and transplants using stem cells from bone marrow and umbilical cord blood. The program will allocate $23 million annually for the National Cord Blood Inventory Program and $30 million annually for the C.W. Bill Young Cell Transportation Program through 2020. The terms of the bill do not reauthorize stem cell research from destroyed human embryos, which is a more contentious issue.

ACE910 Receives Breakthrough Designation from the FDA The U.S. FDA granted breakthrough therapy designation to the investigational drug ACE910 for the prophylactic treatment of hemophilia A with factor VIII (FVIII) inhibitors in patients 12 years old and older. The “breakthrough therapy” designation is designed to accelerate the development and review of medicines that demonstrate early clinical evidence of a substantial improvement over current treatment options for serious diseases. The FDA’s decision was based on the results of a phase I trial, as well as a subsequent phase I/II extension study, in which ACE910 was administered as a weekly subcutaneous injection in patients with hemophilia A with and without inhibitors to factor VIII. In the phase I trial, which included 18 patients, treatment with a weekly subcutaneous injection of ACE910 led to a decrease in annualized bleeding rate (compared with ABR 6 months prior to study enrollment) among all patients: from 32.5 to 1.7 in the 0.3 mg/kg cohort (n=6); from 18.3 to 0 in the 1 mg/kg cohort (n=6); and from 15.2 to 0 in the 3 mg/kg cohort (n=6). In terms of safety, adverse events were observed in 18 patients and all were reported as mild or moderate; the most common of these was injection site erythema. There was also no evidence of clinically relevant abnormalities of coagulation (determined by clinical findings and laboratory tests) in all cohorts, and there were no thromboembolic adverse events observed.
