New drugs

FDA has approved Celgene’s apremilast (Otezla) 30 mg to treat adults with active psoriatic arthritis (PsA), a condition characterized by joint pain, stiffness, swelling, and impaired physical function. The product, an inhibitor of phosphodiesterase-4 (PDE-4), is the first oral therapy formulated for this condition. It is dosed twice daily. In clinical trials, the most common side effects observed in patients were diarrhea, nausea, and headache. FDA is requiring a pregnancy exposure registry as a post-marketing requirement to assess the risks to pregnant women related to apremilast exposure. (www.otezla.com)

FDA has approved Mallinckrodt’s oxycodone hydrochloride/acetaminophen 7.5 mg/325 mg extended-release tablets (CII) (Xartemis XR), dosed two tablets every 12 hours, for the management of acute pain requiring opioid treatment. This product is also indicated for patients unresponsive to other treatments. It is the first and only extended-release oral combination of two pain medications, delivering both immediate and extended relief. The product begins to affect symptoms in less than 60 minutes. Serious adverse events may include respiratory depression and hepatotoxicity. Common adverse events include nausea, dizziness, headache, vomiting, constipation, and somnolence. Approval included a boxed warning for addiction, abuse, and misuse; life-threatening respiratory depression; accidental exposure; neonatal opioid withdrawal syndrome; and hepatotoxicity.

The single-dose tray will remain available. (http://www.bydureon.com)

Teva has launched loxapine inhalation powder, 10 mg (Adasuve), the first orally inhaled drug for the acute treatment of agitation associated with schizophrenia or bipolar 1 disorder in adults. Administration is performed with Staccato, a single-use, hand-held device from Alexza Pharmaceuticals. The device provides rapid systemic drug delivery as the patient inhales a thermally-generated aerosol of loxapine, a first generation antipsychotic. Absorption is rapid, with a maximum plasma concentration achieved in approximately two minutes. (www.adasuve.com)

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. Apixaban is also approved to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. The new treatment option is dosed twice daily, and routine coagulation is not required. 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)
