Boehringer Ingelheim Receives Recommendation From EU Scientific Committee for Sifrol(R)/ Mirapexin(R) (Pramipexole) for the Treatment of Restless Legs Syndrome (RLS)

Ingelheim, Germany (ots/PRNewswire)

- For Non-US Healthcare Professional Media
Boehringer Ingelheim announced today that that the Committee for
Medicinal Products for Human Use (CHMP) of the European Medicines
Agency (EMEA) has issued a positive opinion recommending approval of
Sifrol(R) / Mirapexin(R) (pramipexole) for the treatment of Restless
Legs Syndrome (RLS) in the European Union. Pramipexole is a dopamine
agonist currently approved for the treatment of Parkinson's Disease.
A supplementary new drug application (sNDA) has been filed with the
US Food and Drug Administration (FDA) to include treatment of RLS in
the US label also.
"Restless Legs Syndrome is a common yet very under-diagnosed
condition which adversely affects the lives of millions of people
worldwide. Global epidemiologic and quality of life studies show a
significant impact on RLS-patients' quality of life, comparable to
that of cardiovascular diseases [1]. The recommendation from the EU
scientific committee will be welcomed by the clinical community as it
reflects recognition of the need for effective treatment options for
the many patients who are suffering from this debilitating
condition." Professor Claudia Trenkwalder, Department of Clinical
Neurophysiology, University of Goettingen, Goettingen, Germany,
commented.
"Boehringer Ingelheim is committed to improving the lives of
patients suffering from Restless Legs Syndrome," said Dr. Andreas
Barner, member of the Board of Managing Directors of Boehringer
Ingelheim and responsible for Research & Development and Medicine.
"The recommendation from the CHMP is a major step towards an approval
for pramipexole in the European Union. A final decision from the
European Commission could be expected in the second quarter of 2006.
Pramipexole is already well established in the treatment of
Parkinson's Disease - our hope is that soon RLS patients will be able
to benefit from the efficacy of pramipexole in controlling not only
the symptoms of RLS, but also in reducing the high impact of the
disease on patients' quality of life."
If approved, this pharmaceutical treatment for Restless Legs
Syndrome will be marketed throughout the European Union by Boehringer
Ingelheim.
The CHMP Opinion stated that Sifrol(R)/Mirapexin(R) tablets are
indicated for the symptomatic treatment of moderate to severe
idiopathic Restless Legs Syndrome in dosages up to 0.54 mg of base
(0.75 mg of salt).
Efficacy in treating RLS
The registration programme for pramipexole included more than
1,000 patients in Europe and the United States. These study results
have confirmed that pramipexole provides rapid relief from symptoms
after just one week of starting treatment. Pramipexole is highly
efficacious at the starting dose of 0.125mg single dose per day and
up to 0.75mg single dose per day[2] and is well tolerated
[3],[4],[5].
The efficacy and tolerability of pramipexole in RLS continues to
be investigated in a comprehensive clinical trials programme with
more than 1,000 patients, to further assess the therapeutic potential
in this condition.
About Restless Legs Syndrome (RLS)
RLS is a neurological disorder characterised by an uncontrollable
urge to move the legs, usually accompanied by unpleasant and
sometimes painful sensations in the legs. RLS affects up to ten
percent of the population aged between 30 and 79 years[6] and around
one-third of sufferers experience symptoms more than twice weekly
causing moderate to severe distress[7]. The motor-restlessness
worsens during the evening and night causing difficulty initiating
and maintaining sleep. The sleep disruption can lead to excessive
daytime sleepiness and compromise work performance. RLS also has
considerable impact on social activities that require immobility.
About pramipexole
Pramipexole, a compound from Boehringer Ingelheim research, is
currently approved for the treatment of the signs and symptoms of
idiopathic Parkinson's Disease, as monotherapy or in combination with
levodopa. The most commonly reported adverse reactions in early and
late Parkinson's disease in clinical trials were dizziness,
dyskinesia, headache, insomnia, somnolence, constipation, nausea,
hallucinations visual, orthostatic hypotension and fatigue. Patients
have reported falling asleep without perceived warning signs during
activities of daily living, including operation of a motor vehicle,
which sometimes resulted in accidents. As also described in the
literature for antiparkinsonian dopamine replacement therapy, cases
of behavioural changes have been reported.
