FDA approves Baxalta's drug Adynovate for rare bleeding disorder

"The approval of Adynovate provides an important therapeutic option for use in the care of patients with Hemophilia A and reduces the frequency of Factor VIII infusions needed to avoid bleeding," said Karen Midthun, M.D., director of the FDA's Center for Biologics Evaluation and Research.

Hemophilia A is an inherited, sex-linked, blood-clotting disorder that primarily affects males, which is caused by defects found in the Factor VIII gene. According to the Centers for Disease Control and Prevention, Hemophilia A affects one in every 5,000 male births in the United States. Patients with hemophilia A may experience repeated episodes of serious bleeding, primarily into the joints, which can be severely damaged as a result.

The safety and efficacy of Adynovate were evaluated in a clinical trial of 137 adults and adolescents aged 12 years and older, which compared the recommended routine prophylactic (preventative) treatment regimen to on-demand therapy. The trial demonstrated that Adynovate was effective in reducing the number of bleeding episodes during routine care. Additionally, Adynovate was effective in treating and controlling bleeding episodes. No safety concerns were identified during the trial.

Adynovate is manufactured by Baxalta US Inc., based in Westlake Village, California.

 

Hemophilia is a rare bleeding disorder in which the blood fails to clot normally. Seven out of 10 people have severe form of the disorder, according to the National Institutes of Health.

Patients with the disorder experience repeated episodes of serious bleeding, primarily in the joints, which can be severely damaged.

Baxalta, spun off from Baxter International Inc earlier this year, developed Adynovate in partnership with Nektar Therapeutics Inc.
