Expert Panel Publishes Findings on Benefits of UnderutilizedIntrathecal Baclofen Therapy for Severe Spasticity in MultipleSclerosis Patients

Consensus Paper Suggests Medtronic ITB Therapy is an EffectiveTreatment for Control of Severe Spasticity, a Frequent andDisabling Symptom of MS

MINNEAPOLIS–(BUSINESS WIRE)–A new scientific article has beenpublished demonstrating the profound impact of spasticity onpatients with multiple sclerosis and the benefits andunderutilization of intrathecal baclofen (ITB) therapy fromMedtronic, Inc. (NYSE: MDT) as a treatment option for thesepatients. The paper, published this week as an OnlineFirst articlein Multiple Sclerosis Journal, recommends physician evaluation ofITB therapy as a treatment option for patients at all clinicalstages of MS who are intolerant of or unresponsive to oralspasticity therapies.

“Severe spasticity is a debilitating condition that canhave a negative impact on quality of life of patients with MS.While oral medications work to treat spasticity in someindividuals, I see patients every day who can’t tolerate theside effects of large doses of medication necessary to treat themost severe cases,” said Mary Hughes, M.D., one of thearticle’s authors and chair, Division of Neurology,University Medical Group, Greenville Hospital system UniversityMedical Center in Greenville, S.C. “The strong collection ofclinical results on the use of ITB therapy in MS patients points toa clear need for physicians to help MS patients control theirspasticity and restore quality of life with options like ITBtherapy, which is safe and effective in carefully selectedpatients.”

The expert panel of authors, including leading MS cliniciansfrom the United States and Europe, combined has more than 100 yearsof experience in MS management and has treated more than 1,500 MSpatients worldwide. The article includes a review of literature onITB therapy for spasticity in MS and provides expert opinion of thepanel regarding patient selection and management of ITB therapy inMS patients. Medtronic sponsored the panel’s meeting andpaper development.

According to survey results within the research summary, 84percent of patients with MS reported at least some symptoms ofspasticity, with 30 percent reporting moderate to severe symptoms.Of the 13 percent of MS patients who may be candidates for ITBtherapy, only 1 percent of patients stated they were receiving thetherapy. however, current data indicate that ITB therapyeffectively and significantly reduces severe spasticity inambulatory and non-ambulatory patients with MS.

The expert panel noted that the main barrier to the use of ITBtherapy is that many physicians do not present ITB as a therapeuticoption that is safe, effective and well-tolerated. this oftenoccurs due to a lack of physician understanding of quality of lifeissues caused by spasticity, potential ITB benefits and appropriatepatient selection, as well as their focus on disease-modifyingtherapies rather than symptom control.

“this article is a very powerful analysis of the need forgreater consideration of ITB therapy by clinicians who manageMS,” said Tom Tefft, senior vice president and president ofthe Neuromodulation business at Medtronic. “We are hopefulthat this paper will encourage more physicians to offer the therapyto appropriate patients.”

About Multiple Sclerosis and Spasticity

Approximately 300,000 Americans have MS, a chronic, oftendisabling disease of the central nervous system. Symptoms mayinclude abnormal fatigue, impaired vision, loss of balance andmuscle coordination, slurred speech, tremors, spasticity, bladderand bowel problems, difficulty walking, short-term memory loss,mood swings, and, in severe cases, partial or complete paralysis.Spasticity can occur when the part of the brain that controlsvoluntary movements is damaged or injured and results in tight,stiff muscles. in addition to being one possible symptom of MS,spasticity also can be a symptom of cerebral palsy, brain injury,spinal cord injury or stroke. For some people, the condition is sosevere that it is impossible to voluntarily relax muscles.

Medtronic ITB Therapy using the SynchroMed® II pump is thefirst and only fully programmable implantable drug pump availablein the United States to treat severe spasticity. First approved inthe United States in 1992, ITB is a complete drug delivery solutionto optimize spasticity treatment and maximize function. The therapydelivers a baclofen injection directly to the intrathecal spacewhere fluid flows around the spinal cord in patients with severespasticity.
