Neurocrine Biosciences gets FDA OK for movement disorder drug

April 11 (Reuters) - The U.S. Food and Drug Administration on Tuesday approved Neurocrine Biosciences Inc’s drug to treat tardive dyskinesia, a side effect of antipsychotic medications characterized by uncontrolled movement of the face and body, the company said. The drug, Ingrezza, is the first treatment to be approved for the irreversible disorder, which occurs in 5 percent to 8 percent of patients taking antipsychotic drugs. Ingrezza is the company’s first commercial product.

The San Diego-based company did not immediately give a price for the drug. Last year, it said it would price Ingrezza at a net price of between $20,000 to $60,000 per year, depending on the required dosage.

Wall Street analysts, on average, forecast annual sales for the drug of around $700 million by 2023, according to Thomson Reuters data.

Ingrezza, or valbenazine, is designed to block a protein found in the brain that helps regulate the amount of dopamine released into nerve cells. Antipsychotic drugs are designed to block dopamine receptors, but in some patients the signal gets amped up and more dopamine is released in a region of the brain that controls movement,

Around 500,000 Americans suffer from tardive dyskinesia, Neurocrine Biosciences Chief Executive Officer Kevin Gorman said in an interview.

He estimated that, at best, around 100,000 of them would be treated with Ingrezza, but a more realistic level would be around 50,000. (Reporting by Deena Beasley; Editing by Jonathan Oatis)
