Johnson & Johnson's (JNJ) Janssen Pharmaceutical Cos. unit on Tuesday said it filed a new drug application with the U.S. Food and Drug Administration for its esketamine nasal spray in treatment-resistant depression in adults.

The drug maker said esketamine, if approved, would provide the first new mechanism of action in 30 years to treat the mental illness. Janssen said almost 300 million people suffer from major depressive disorder worldwide, and about a third of them don't respond to currently available treatments.

Janssen said the NDA is based on five pivotal Phase 3 studies that showed treatment with esketamine nasal spray plus a newly initiated oral antidepressant was associated with rapid reduction of depressive symptoms and delayed time to relapse of symptoms of depression.

The FDA previously granted breakthrough-therapy designations for esketamine in treatment-resistant depression and in major depressive disorder with imminent risk for suicide. Janssen said it is currently conducting Phase 3 studies for the second indication.

The company said it will seek European approval for the esketamine treatment-resistant depression indication later this year.
