FDA Issues a Complete Response Letter for New Drug Application for Dasotraline for the Treatment of ADHD

MARLBOROUGH, Mass.--(BUSINESS WIRE) August 31, 2018 --Sunovion Pharmaceuticals Inc. (Sunovion) today announced that the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter for the New Drug Application (NDA) for dasotraline, a novel dual-acting dopamine and norepinephrine reuptake inhibitor (DNRI), for the treatment of attention-deficit hyperactivity disorder (ADHD).

Upon completion of their review, the FDA determined that they cannot approve the dasotraline NDA for the treatment of ADHD in its current form. The Agency indicated that additional clinical data are needed to further evaluate the efficacy and tolerability of dasotraline for the treatment of ADHD. Sunovion plans to meet with the FDA to discuss their comments and determine next steps.

Dasotraline was evaluated in approximately 2,500 children and adults with ADHD in multiple placebo-controlled safety and efficacy studies,1,2,3,4 as well as two long-term safety studies.

“While we are disappointed with the FDA’s decision, we remain confident in the future of dasotraline,” said Antony Loebel, M.D., Executive Vice President and Chief Medical Officer at Sunovion, Head of Global Clinical Development for Sumitomo Dainippon Pharma Group. “We plan to discuss next steps for the dasotraline ADHD program with the FDA as soon as possible.”

Dasotraline is also being studied for the treatment of moderate to severe binge eating disorder (BED) in adults in the U.S. Data from two positive pivotal studies5,6 will support an expected marketing application submission to the FDA for dasotraline to treat BED in FY2018.

About Dasotraline

Dasotraline is a new chemical entity that acts as a dual dopamine and norepinephrine reuptake inhibitor (DNRI). It has an extended half-life (47-77 hours in adults; 58-84 hours in children) that supports the potential for stable plasma concentrations yielding a continuous therapeutic effect over the 24-hour dosing interval.

Dasotraline was discovered by Sunovion Pharmaceuticals Inc. and is currently in development to evaluate its use in treating ADHD and BED. It has not been approved by the FDA for the treatment of ADHD or BED.

About Attention-Deficit Hyperactivity Disorder (ADHD)

ADHD is a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning and development, as characterized by inattention (e.g., distractibility, forgetfulness) and/or hyperactivity and impulsivity (e.g., fidgeting, restlessness).7 Approximately 11.0 percent of children 4 to 17 years of age have been diagnosed with ADHD in the U.S.8 Up to 60.0 percent of children with ADHD continue to experience symptoms into adulthood.9 It is estimated that 4.4 percent of adults between ages 18 and 44 years experience some symptoms and disabilities from ADHD in the U.S.10

In children, ADHD is associated with social rejection and reduced school performance.11 Children with a history of ADHD are ten times as likely to have difficulties with friendships and can have more frequent and severe injuries than peers without ADHD.12 In adults, symptoms reduce the quality of social or occupational functioning.5 Studies have shown that ADHD is associated with higher levels of unemployment, and those who are employed may experience workplace impairment, reduced productivity and behavioral issues.13 Adults with ADHD are also at increased risk of trauma, workplace injuries and traffic accidents, are more likely to be diagnosed with comorbid mental health conditions and have a higher incidence of separation and divorce.14,15,16
