Theravance, Inc. (THRX) Announces Initiation of Phase 2 Study With TD-9855 for the Treatment of Fibromyalgia


12/5/2012 9:48:54 AM

SOUTH SAN FRANCISCO, CA--(Marketwire - December 04, 2012) - Theravance, Inc. (NASDAQ: THRX) announced today the initiation of a fibromyalgia Phase 2 study with TD-9855, the lead compound in Theravance's Monoamine Reuptake Inhibitor program. TD-9855 is an investigational norepinephrine and serotonin reuptake inhibitor (NSRI) for the treatment of central nervous system (CNS) conditions such as chronic pain and Attention-Deficit/Hyperactivity Disorder (ADHD).

"We are enthusiastic about the potential of TD-9855 to treat patients suffering from fibromyalgia," said Mathai Mammen, M.D., Ph.D., Senior Vice President of Research and Early Clinical Development. "There remains a substantial opportunity for therapies with an acceptable tolerability profile that effectively manage both fibromyalgia and commonly experienced comorbid symptoms such as fatigue. We believe TD-9855's balance of inhibition of norepinephrine and serotonin reuptake may provide a compelling and differentiated profile versus current alternatives."

About the Phase 2 Study in Fibromyalgia

This Phase 2 proof-of-concept study will evaluate the safety and efficacy of two doses of TD-9855 in patients with fibromyalgia. Approximately 375 patients will be randomized to TD-9855 or placebo. Study medication will be administered once-daily for up to 9 weeks. The primary endpoint of the study is improvement in pain. Additional secondary or exploratory endpoints will assess improvement in other established fibromyalgia measures and impact on important comorbidities, such as fatigue.

About TD-9855 and the Monoamine Reuptake Inhibitor Program

TD-9855 is an investigational NSRI discovered by Theravance for the treatment of CNS conditions such as chronic pain and ADHD. 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. Data collected from a Phase 1 positron emission tomography (PET) study confirmed CNS penetration and selectivity for norepinephrine over serotonin transporters. TD-9855 exhibits broad preclinical antinociceptive activity across a range of models of pain, including acute inflammatory, neuropathic and osteoarthritis models. TD-9855 does not interact with opioid receptors but augments the analgesic effects of morphine. The antinociceptive activity of TD-9855 reflects occupancy of both norepinephrine and serotonin transporters, at exposures that were associated with submaximal occupancy of central serotonin transporters. In addition to the Phase 2 study in fibromyalgia, TD-9855 is being evaluated in an ongoing Phase 2 safety and efficacy study in adults with ADHD. The goal of the Monoamine Reuptake Inhibitor program is to develop a best-in-class monoamine reuptake inhibitor for the treatment of various CNS conditions such as chronic pain, ADHD, and potentially depressive disorders.

About Fibromyalgia

Fibromyalgia is a chronic functional illness that is characterized by pain, stiffness, and tenderness of muscles, tendons, and joints. It has been estimated to affect as many as 5 million individuals in the United States.
