CHMP adopts positive opinion recommending approval of Exelon� as first symptomatic treatment of mild to moderately severe dementia associated with idiopathic Parkinsonís disease in the EU


Basel, Switzerland, January 30, 2006 - Novartis announced that it has received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) recommending that the European Commission grant a marketing authorization for Exelon� (rivastigmine tartrate) for the symptomatic treatment of mild to moderately severe dementia associated with idiopathic Parkinsonís disease (PD) later this year.

This decision coincides with the approval of Exelon as the first treatment for dementia associated with PD in Switzerland. Exelon already received marketing authorization for this indication in several Latin American countries, including Brazil. This makes Exelon, currently indicated for Alzheimerís dementia, the only cholinesterase inhibitor to be authorized for more than one type of dementia.

ďThis is encouraging news for Parkinsonís patients who are affected by dementia,Ē said James Shannon, Global Head of Development, Novartis Pharma AG. ďAlthough movement symptoms of Parkinsonís disease can be managed quite well with current treatments, dementia associated with Parkinsonís disease could not be treated until now. Novartis hopes that Exelon will soon be approved for this new indication in many more countries around the world.Ē

Since 1997, Exelon has been widely used to treat mild to moderate Alzheimerís disease dementia in over 70 countries. It belongs to a class of drugs known as cholinesterase inhibitors (ChEIs) which increases the communication between certain nerve cells in the brain.

Exelon is the first medication worldwide that has also shown significant benefits in the treatment of Parkinsonís patients suffering from dementia in a large-scale, randomized, well-controlled study involving 541 patients from 12 study centers in Europe and Canada. Based on this study, submissions to health authorities were made.

At any one time, up to 40 percent of people with Parkinsonís disease suffer from dementia[1]. Patients with dementia associated with Parkinsonís disease typically have problems with memory, concentration, activities of daily living, as well as depression, anxiety, apathy and hallucinations[2]. However, probably due to the absence of treatment, current diagnosis rates are low.

ďDementia associated with Parkinsonís disease is a significant emotional, economic and social burden for patients and their families,Ē said Mary Baker, President of the European Parkinsonís Disease Association, London. ďWe therefore welcome therapies like Exelon which give new hope to families caring for a loved one with dementia and may improve the quality of life of the whole family.Ē

About the EXPRESS study
The regulatory submissions were based on the EXPRESS study (EXelon in PaRkinsonís disEaSe dementia Study), published in December 2004 in the New England Journal of Medicine[3]. EXPRESS is the first large-scale clinical study assessing the efficacy and safety of any treatment in Parkinsonís disease patients with dementia. Patients taking Exelon showed statistically significant benefits on a range of symptoms, such as maintaining or improving memory, concentration and behavioral problems. They were also able to cope better with everyday activities like watching TV or talking about current events.

The side effects associated with Exelon during this study were mild to moderate in nature and included nausea and vomiting. Importantly, motor scale assessments showed that Parkinsonian symptoms were not worsened overall relative to baseline or placebo. Mild to moderate tremor was reported in 10% of Exelon-treated patients, but this resulted in relatively few withdrawals from the study.

About Exelon
Exelon is a treatment for mild to moderate Alzheimerís disease. It belongs to a class of drugs known as cholinesterase inhibitors (ChEIís) which increase the activity of the neurotransmitter acetylcholine in the brain. Among the widely used ChEIís, Exelon is the only treatment that inhibits both enzymes involved in the breakdown of this neurotransmitter - acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). This may offer additional benefits over treatments which inhibit AChE alone. Exelon can maintain both memory and thinking, help with behavioral problems and affect how patients cope with the activities of daily living. It may help them communicate better, interact socially, participate in hobbies and in activities of daily living [4],[5].

About Parkinsonís Disease Dementia
Parkinsonís disease is a chronic and progressive neurological condition estimated to affect 6.3 million people worldwide[6]. Dementia is thought to occur in up to 40 percent of patients diagnosed with this disease and may affect up to 80 percent of Parkinsonís patients in advanced age and severe disease1,[7]. Parkinsonís patients have a six-fold increase in the risk of developing dementia compared with elderly people without Parkinsonís disease.[8]

Like Alzheimerís disease, dementia associated with Parkinsonís disease is thought to result partly from a cholinergic deficit, which causes decreased transmission of signals between nerves in the brain, especially those that rely on the neurotransmitter acetylcholine.

Dementia associated with Parkinsonís disease differs clinically from Alzheimer disease. Patients with dementia associated with Parkinsonís disease generally suffer from an impairment of executive function like the ability to plan or organize and goal-directed behavior. Furthermore they have more severe visuospatial deficits, apathy, severe attentional deficits with fluctuations and frequent visual hallucinations.
