Acquisition of clinical-stage company in ADHD widens Otsuka’s presence in mental health
Tokyo, Japan – March 3, 2017 – Otsuka Pharmaceutical Co., Ltd. (OPC) today announces an agreement with Neurovance, Inc. (Neurovance) under which OPC has agreed to acquire Neurovance, a privately held, venture-funded, clinical stage pharmaceutical company focused on attention-deficit hyperactivity disorder (ADHD) and related disorders.  
Under the terms of the agreement, Otsuka America, Inc. (OAI), a subsidiary of OPC, is to provide an estimated USD $100 million in upfront payments at closing, up to $150 million in additional payments contingent on achievement of development and approval milestones, and future additional payments contingent on achievement of sales milestones. The contract was signed on March 2 (U.S. Eastern Standard Time), and the transaction closing is expected to occur in the second quarter of 2017, subject to customary closing conditions.
Neurovance is developing centanafadine (CTN, formerly EB-1020) for the treatment of attention-deficit hyperactivity disorder in adult and pediatric patients. The company is based in Cambridge, Mass., and was established as a spin-off from Euthymics Bioscience, Inc. in 2011.
Centanafadine is a non-stimulant, triple reuptake inhibitor that modulates norepinephrine, dopamine and serotonin reuptake with the intent of improving focus, attention, and specific higher level cognitive skills in patients with ADHD. Two phase II clinical trials in adults, including a phase IIb trial, have been completed for centanafadine, setting the stage for the start of phase III trials in ADHD.
Tatsuo Higuchi, president and executive director, Otsuka Pharmaceutical Co., Ltd. commented, “Otsuka has been investing prudently in acquiring assets and collaborating on the development of new technologies that address specific patient needs in the central nervous system, cardio-renal and oncology therapeutic areas. Neurovance’s resources will be a welcomed, integral part of our activities in CNS.”
The acquisition of Neurovance is an extension to ADHD of Otsuka’s strategy in the CNS therapy area to develop new products that can also address issues of importance to patients such as compliance with medicine taking or the challenging side effects from existing medications. Centanafadine is a non-stimulant drug candidate which in its development to date has shown that it may achieve comparable efficacy to stimulant drugs with a potentially lower risk of abuse.  
Following the consummation of the transaction, Neurovance will be an indirect, wholly-owned subsidiary of Otsuka Pharmaceutical Co., Ltd.
About ADHD
Attention-deficit hyperactivity disorder (ADHD) is a CNS disorder marked by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. Some people with ADHD only have problems with one of the behaviors, while others have symptoms of both inattention and hyperactivity-impulsivity. Most children with ADHD have the combined type.
ADHD symptoms often appear in childhood and can continue through adolescence and adulthood. Symptoms of ADHD can be mistaken for emotional or disciplinary problems or missed entirely in quiet, well-behaved children, leading to a delay in diagnosis. Adults with undiagnosed ADHD may have a history of problems at work, difficult or failed relationships, or poor academic performance.
Scientists are not sure what causes ADHD. Like many other illnesses, a number of factors can contribute to ADHD, such as genes, exposure to cigarette smoking, alcohol use, drug use  or environmental toxins during pregnancy, low birth weight, or brain injuries. ADHD is more common in males than females. Other conditions, such as learning disabilities, anxiety disorder, conduct disorder, depression, and substance abuse, are common in people with ADHD.[i]
Attention-deficit hyper activity disorder affects both children and adults. The lifetime prevalence of ADHD in adolescents aged 13 to 18 in the U.S. is 9%, and of those, 1.8% are classified as “severe.” [ii] In U.S. adults aged 18 and older, the lifetime prevalence is 8.1% with the average age of onset being 7.[iii]  The 12-month prevalence in U.S. adults is 4.1%, with 41.3% of those being classified as “severe.”[iv] The global market size for attention-deficit hyperactivity disorder therapies was USD $11.2 billion in FY 2016.[v]
