New FDA Approvals: FDA Expands Bivigam Patient Population

Dec. 8: The FDA expanded the patient population of ADMA Biologics, Inc.’s Bivigam (immune globulin intravenous, human) to include the treatment of people at least 2 years old with primary humoral immunodeficiency. The agency initially approved the therapy on Dec. 21, 2012. The initial intravenous infusion rate is 0.5 mg/kg/minute for the first 10 minutes for a dose of 300-800 mg/kg every three to four weeks. The maintenance infusion rate may be increased every 20 minutes by 0.8 mg/kg/minute up to 6 mg/kg/minute. Drugs.com lists the price of a 50 mL intravenous solution as more than $756.

Dec. 13: The FDA approved US WorldMeds’ Iwilfin (eflornithine) to reduce the risk of relapse in adult and pediatric patients with high-risk neuroblastoma (HRNB) who have demonstrated at least a partial response to prior multiagent, multimodality therapy, including anti-disialoganglioside (anti-GD2) immunotherapy. Between 700 and 800 cases of neuroblastoma are diagnosed annually in the U.S., with 90% of those before age 5. About half of those cases in children are HRNB. The agency used the Real-Time Oncology Review pilot program and the Assessment Aid. It also granted the application priority review and breakthrough drug and orphan drug designations. The recommended dosing of the tablet is based on body surface area.
