Theravance Announces Initiation of Phase 2 Study With Its MARIN Compound, TD-9855, for the Treatment of ADHD

SOUTH SAN FRANCISCO, CA--(Marketwire - Dec 12, 2011) - Theravance, Inc. (NASDAQ: THRX) announced today the initiation of an Attention-Deficit/Hyperactivity Disorder (ADHD) Phase 2 study with TD-9855, the lead compound in Theravance's MonoAmine Reuptake INhibitor (MARIN) program. TD-9855 is an investigational norepinephrine and serotonin reuptake inhibitor (NSRI) for the treatment of central nervous system (CNS) conditions such as ADHD and chronic pain.

"We are excited that our internal discovery group has produced another compound with the potential to make a meaningful difference in the lives of patients. In preclinical studies, TD-9855 was shown to be a dual norepinephrine and serotonin reuptake inhibitor with modest selectivity for norepinephrine over serotonin. We are encouraged by this profile and believe TD-9855 has the potential to treat ADHD symptoms and provide additional benefit in the treatment of comorbid disorders such as depressive and anxiety spectrum disorders," said Mathai Mammen, M.D., Ph.D., Senior Vice President of Research and Early Clinical Development.

"We are pleased with the initiation of this Phase 2 study with TD-9855. We believe there is a specific need for medicines that are efficacious and well-tolerated treatments for multiple CNS conditions," said Rick E Winningham, Chief Executive Officer.

About the Phase 2 Study in ADHD
This Phase 2 proof-of-concept study will evaluate the safety and efficacy of two different doses of TD-9855 in adult male patients with ADHD. Approximately 285 patients will be randomized to TD-9855 or placebo. Therapy will be orally administered once-daily for 6 weeks. The primary endpoint of the study is improvement in symptoms as assessed by Adult ADHD Investigator Symptom Rating Scale (AISRS). A key secondary endpoint is improvement in executive function, which will be measured using the Barkley Deficits in Executive Functioning Scale (BDEFS).

About TD-9855 and the MARIN Program
TD-9855 is an investigational NSRI discovered by Theravance for the treatment of CNS conditions such as ADHD and chronic pain. TD-9855 has been administered to healthy volunteers in ascending single- and multiple-dose studies evaluating safety, tolerability and pharmacokinetics. The results of these studies showed that TD-9855 was generally well tolerated, had a predictable and linear pharmacokinetic profile and a long pharmacokinetic half-life supportive of once-daily dosing. In addition, data collected from a Phase 1 positron emission tomography (PET) study confirm CNS penetration and selectivity for norepinephrine over serotonin transporters. The goal of the MARIN program is to develop a best-in-class monoamine reuptake inhibitor for the treatment of various CNS conditions such as ADHD, chronic pain and potentially depressive disorders.
