Noven Announces Positive Phase 2 Results of
Investigational d-Amphetamine Transdermal System For ADHD

Noven Pharmaceuticals, Inc., a wholly-owned subsidiary of Hisamitsu Pharmaceutical Co., Inc., today announced top-line results from its Phase 2 clinical study evaluating d-Amphetamine Transdermal System (d-ATS) for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents. Currently, there is no amphetamine-based transdermal treatment option available for ADHD.

The Phase 2 study was a randomized, double-blind, placebo-controlled, crossover, laboratory classroom study to evaluate the safety and efficacy of d-ATS compared to placebo in subjects 6 to 17 years of age. The 7-week study enrolled 110 patients. 

The primary outcome measure in the study was mean total SKAMP score for d-ATS compared to placebo. The SKAMP scale measures manifestations of ADHD symptoms using an independent observer (teacher) rating of the child's impairment in classroom behavior. The Phase 2 study achieved the primary endpoint with statistical significance, and no serious adverse events were reported. 

Joel S. Lippman, M.D., Noven’s Executive Vice President & Chief Medical Officer, said: “We are pleased with the results of our d-ATS Phase 2 study, and are preparing to advance the program into Phase 3 development.”
