Bristol-Myers Squibb and Pfizer announced that FDA has approved a new indication for apixaban (Eliquis) to reduce the risk of blood clots after surgery to replace knees or hips.

A boxed warning notes increased stroke risk for patients with nonvalvular atrial fibrillation who discontinue use without adequate continuous anticoagulation, as well as increased risk of epidural or spinal hematoma. Three clinical trials enrolling more than 11,000 patients assessed the safety and efficacy of the product. (www.eliquis.com)

It is indicated for use by patients 12 years of age and older who remain symptomatic despite treatment with H1-antihistamine therapy. Omalizumab is not used to treat other forms of urticaria (hives) and is not for use in children less than 12 years of age. It is administered by subcutaneous injection. Omalizumab is the first biologic treatment and first medication approved by FDA for CIU since H1-antihistamines. Nearly 50% of patients remain symptomatic despite treatment with approved doses of H1-antihistamines. (www.xolair.com.)
FDA has approved the pediatric drug propranolol hydrochloride (Hemangeol, Pierre Fabre Pharmaceuticals), the first and only treatment approved for proliferating infantile hemangioma requiring systemic therapy. While propranolol is a long-established agent in cardiology treatment, no pharmaceutical form was approved for pediatric use before clinical trials were launched in 2009. When the product was studied in infants five weeks to five months old, the oral solution, dosed at 3 mg/kg/day for six months, showed a 60.4% success rate vs. 3.6% in the placebo group and reached the study’s primary endpoint: complete or nearly complete resolution of the target hemangioma. Adverse reactions included sleep disorders, aggravated respiratory tract infections such as bronchitis and bronchiolitis associated with cough and fever, diarrhea, and vomiting. The product will be available in June. (www.hemangeol.com)
