FDA OKs Glaxo’s Nucala for Hypereosinophilic Syndrome

Share

FDA has approved GlaxoSmithKline’s Nucala (mepolizumab) for adults and children aged 12 years and older with hypereosinophilic syndrome (HES) for six months or longer without another identifiable non-blood related cause of the disease. The new indication for Nucala is the first approval for HES patients in nearly 14 years, according to an FDA release. The rare disorders group is associated with persistent eosinophilia with evidence of organ damage. Symptoms include skin rashes, itching, asthma, difficulty breathing, abdominal pain, vomiting, diarrhea, arthritis, muscle inflammation, congestive heart failure, deep venous thrombosis and anemia, the agency says.

 

Approval was based on data from a randomized, double-blind, multicenter, placebo-controlled trial in 108 patients with HES. “Fewer patients in the Nucala treatment group (28%) had HES flares compared to patients in the placebo group (56%), with a 50% relative reduction,” FDA says. “In addition, the time to the first HES flare was later, on average, for patients treated with Nucala vs. placebo.”

 

Nucala was originally approved in 2015 to treat patients age 12 years and older for severe asthma with an eosinophilic phenotype. The interleukin-5 antagonist monoclonal antibody is produced by recombinant DNA technology in Chinese hamster ovary cells, FDA says.
