FDA Approves Myalept for Rare Metabolic Disorder

Drug is meant for people with deficiency of the hormone leptin

WEDNESDAY, Feb. 26, 2014 (HealthDay News) -- Myalept (metreleptin for injection) has been approved by the U.S. Food and Drug Administration to treat complications of leptin deficiency for people with the congenital or acquired generalized forms of lipodystrophy.

People with lipodystrophy are at greater-than-average risk of developing serious insulin resistance at a young age, making them more prone to uncontrolled diabetes and high levels of triglycerides.

Myalept was evaluated in a clinical study of 48 people with generalized lipodystrophy and its complications. The trial showed good results in blood glucose control and reduced triglycerides, the FDA said.

People taking Myalept may develop a resistance to the drug, making it less effective over time and increasing their risk of severe infection, the agency said.

Less serious side effects could include hypoglycemia, headache, weight loss, and abdominal pain. The drug is not recommended for people with general obesity.

The FDA said it has ordered a number of post-marketing studies to further evaluate the drug and its potential to cause serious side effects.

Myalept is marketed by Amylin Pharmaceuticals, based in San Diego.
