Lupin Announces Launch of Orphan Drug NaMuscla® in Germany and the UK for the Treatment of Myotonia in Non-Dystrophic Myotonic Disorders
Zug, Mumbai, February 1, 2019: Lupin is pleased to announce that NaMuscla® (mexiletine) has been launched in Germany and the United Kingdom (UK). NaMuscla® is approved across the European Union (EU) for the symptomatic treatment of myotonia in adults with non-dystrophic myotonic (NDM) disorders. These disorders are a group of rare, inherited neuromuscular conditions in which myotonia, the inability to relax muscles following voluntary contraction, is the most prominent clinical symptom. NaMuscla® reduces myotonia symptoms in adult patients, resulting in a significant improvement in patient quality-of-life and other functional outcomes1,5.
The launch of NaMuscla® in Germany and the UK follows the European Commission’s approval of the product on 18 December 2018. NaMuscla®, designated an Orphan Drug by the European Medicines Agency (EMA), is the first treatment to be licensed across the EU for the symptomatic treatment of myotonia in adults with NDM disorders. The product will be commercialized in Germany by Hormosan Pharma GmbH, a full subsidiary of Lupin Ltd., and in the UK by Lupin Healthcare (UK) Ltd.
“We are delighted to be able to provide patient and market access to NaMuscla® in Germany and the UK,” said Thierry Volle, President EMEA, Lupin. “NaMuscla® is the first licensed therapy for myotonia across the EU and offers an effective treatment option for patients living with this life-altering symptom. We look forward to additional launches for patients in other EU territories through 2019 and 2020.”
Lupin has ongoing partnering discussions for the commercialization of NaMuscla® in European territories outside of Germany and the UK.
About Myotonic Disorders and Non-Dystrophic Myotonic (NDM) Disorders
Myotonic disorders are a group of heterogeneous, inherited, neuromuscular disorders characterized by a shared symptom called myotonia. Myotonia can be described as an inability to relax a contraction of skeletal muscle which originates from a voluntary muscular contraction such as shaking someone’s hand and blinking, or everyday activities such as walking across a street and climbing stairs.
Non-dystrophic myotonias (NDM) are a sub-set of rare (prevalence of 1:100,0006), inherited, myotonic disorders which are caused by mutations within ion channels in the sarcolemma membrane of skeletal muscles. Non-dystrophic myotonias exhibit both sodium and chloride channelopathies which result in altered membrane excitability. For patients with NDM, myotonia is the most prominent symptom and demonstrates different phenotypes in subgroups of NDM disorders, and can affect different parts of the body, such as legs, arms or facial muscles, more severely. Myotonia in NDM patients has an onset in childhood and persists over the patient’s lifetime – significantly impacting the patient’s daily life. Myotonia is described by patients in a variety of ways (stiffness, cramps, pain, difficulty releasing a fist, or difficulty swallowing or eating) which can contribute to substantial delays in diagnosis and treatment, leading to decreased patient quality-of-life and often significant disability.
About NaMuscla® (mexiletine)
NaMuscla® is an antimyotonic agent licensed to treat symptomatic myotonia in adults with non-dystrophic myotonic disorders. In randomized controlled trials, NaMuscla® (167 to 500 mg mexiletine/day) has been shown to significantly reduce myotonia compared to placebo, restoring skeletal muscle hyperexcitability through its use-dependent, voltage-gated, sodium channel-blocking actions which are independent of the cause of channel function. This resulted in an improvement in patient quality-of-life and other functional outcomes, with gastro-intestinal discomfort reported as the most common adverse event, demonstrating NaMuscla® to be safe and generally well tolerated1,5.
