Main Document

$3 Million Upfront Payment to Medtronic for Worldwide Development and Commercialization Rights for Compound Poised for Phase 2 Clinical Development.

Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced that it has licensed worldwide development and commercialization rights to a proprietary magnesium formulation from Medtronic, Inc. (NYSE: MDT), which will be referred to as AC105. Acorda plans to study AC105 as an acute treatment for patients who have suffered neurological trauma, such as a spinal cord injury (SCI) and traumatic brain injury (TBI).

"Acorda has significant experience in the area of spinal cord injury and other neurological injury research. We are excited to leverage that expertise to continue the clinical development of AC105, potentially providing a new therapy to people who suffer debilitating central nervous system injuries," said Ron Cohen, M.D., Acorda's President and CEO. "The acquisition of AC105 is an important addition to our existing pipeline, providing a clinical stage compound to complement GGF2, which is in early Phase 1 clinical trials for the treatment of heart failure, as well as our preclinical programs in remyelination and spinal cord injury."

Acorda made a $3 million upfront payment to Medtronic and will make up to $32 million in regulatory and development milestone payments. A single-digit sales royalty will also be paid by Acorda to Medtronic if AC105 is commercialized by Acorda. Acorda's development and commercialization rights are exclusive in all fields (including SCI, TBI and stroke) for certain formulations of the licensed compound. For other formulations, Acorda's rights are exclusive for indications of interest to Acorda, including SCI, TBI, stroke and all other traumatic and ischemic central nervous system indications, while Medtronic has non-exclusive (with Acorda) development rights in specific areas, including certain areas of pain and musculoskeletal indications.

"Spinal cord injuries and traumatic brain injuries often result in severe, lifelong disability. This places an enormous burden on the person suffering the injury, their caregivers and the healthcare system. The situation is compounded because most spinal cord injuries and traumatic brain injuries occur in young people, leading to long-term care and quality of life issues," said Andrew R. Blight, Ph.D., Acorda's Chief Scientific Officer. "There are currently no FDA-approved therapies for either SCI or TBI, so we are excited to continue research on AC105 to determine its value in improving outcomes for people who suffer these very serious injuries."

In preclinical studies, AC105 demonstrated neuroprotective properties and improvement of locomotor function in SCI and cognitive function in TBI when therapy was initiated within four hours of injury. Medtronic conducted Phase 1 trials in healthy volunteers and Acorda is planning a Phase 2 clinical trial program in SCI, with the potential for subsequent studies in other central nervous system indications, such as TBI and stroke. The U.S. Food and Drug Administration (FDA) granted Fast Track designation on February 12, 2009 for AC105 to improve functional recovery of acute SCI patients. Acorda expects to apply for FDA orphan drug designation for the acute treatment of SCI and will explore orphan drug designations in Europe and in other parts of the world given its worldwide development and commercialization rights.

About Spinal Cord Injury:

Spinal cord injury (SCI) refers to any injury to the spinal cord that is caused by trauma, such as a motor vehicle accident, fall or sports injury. According to the National Spinal Cord Injury Statistical Center (NSCISC), there are between 183,000 and 230,000 people in the United States, and approximately 2 million people worldwide living with a spinal cord injury. Each year, there are 11,000 new injuries reported in the United States. Males account for the majority of spinal cord injury patients with 50-70% of those occurring in those aged 15-35.

The costs of living with SCI can be considerable and can vary greatly due to the severity of injury. Long-term complications from SCI can include neurologic impairments in any body system controlled by the affected nerves. Average annual medical cost for an SCI patient is $15,000-30,000 per year and the annual direct and indirect costs of SCI are estimated at $9.7 billion in the U.S. alone. There are currently no FDA-approved therapies indicated to treat, mitigate, or reverse SCI.

About Traumatic Brain Injury:

Traumatic brain injury (TBI) is caused by a blow or jolt to the head or a penetrating head injury that disrupts the normal function of the brain. TBI can cause a wide range of functional short- or long-term changes affecting thinking, sensation, language, or emotion. TBI can also cause epilepsy and increase the risk for conditions such as Alzheimer's disease, Parkinson's disease, and other brain disorders that become more prevalent with age.

According to World Health Organization, traumatic brain injury (TBI) will surpass many diseases as the major cause of death and disability by the year 2020. With an estimated 10 million people worldwide affected annually by TBI, the burden of mortality and morbidity that this condition imposes on society, makes TBI a pressing public health and medical problem.

In the U.S., approximately 1.6 million people sustain a traumatic brain injury annually and TBI results in approximately 52,000 fatalities and 275,000 hospitalizations every year. Approximately one-third of all hospitalized TBI survivors have long-term disability. TBI is a contributing factor to one third (30.5%) of all injury-related deaths in the United States. Direct medical costs and indirect costs such as lost productivity of TBI totaled an estimated $60 billion in the United States in 2000. There are currently no FDA-approved therapies indicated to treat, mitigate, or reverse TBI.

About Stroke:

Stroke is a disease that affects the arteries leading to and within the brain. It is the third leading cause of death in the United States. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. When that happens, the brain cannot get the blood and oxygen it needs to survive. According to the Centers for Disease Control, strokes are suffered by 15 million people worldwide each year. Of these, 5 million die and another 5 million are permanently disabled. In the United States, approximately 795,000 Americans each year suffer a new or recurrent stroke with more than 137,000 people per year killed by stroke in the U.S. alone. The CDC estimates that Americans paid about $73.7 billion in 2010 for stroke-related medical costs and disability.
