Enables expanded patient access of rare disease medicine to treat myotonia symptoms in non-dystrophic myotonic disorders in three key territories
Mumbai, India | Zug, Switzerland:Pharma major Lupin Limited (Lupin) is pleased to announce that it has entered into distribution agreement with three companies for its orphan drug NaMuscla® (mexiletine). Exeltis Healthcare S.L, Cresco Pharma B.V and Macure Pharma ApS will commercialize NaMuscla®for the symptomatic treatment of myotonia in adults with non-dystrophic myotonic (NDM) disorders in certain EU territories. NaMuscula® is the first and only licensed product for this indication.
NDM disorders are a group of rare, inherited neuromuscular disorders which cause the inability to relax muscles following voluntary contraction. NaMuscla® reduces myotonia symptoms in adult patients, resulting in a significant improvement in patient quality-of-life and other functional and clinical outcomes1. NaMuscla®, which has been designated orphan drug status, received EU marketing authorization in December 2018.
Under the agreements announced today, Exeltis Healthcare S.L will commercialize NaMuscla® in Spain and Portugal, Cresco Pharma B.V will commercialize NaMuscla® in the Netherlands and Macure Pharma ApS in the Nordic countries. Lupin will continue commercialization of NaMuscla® in Germany and UK and will launch the product in Austria and France later this year.
“These distribution agreements represent an important milestone for Lupin as we roll out commercialization of NaMuscla® across Europe. Collaborating with partners that are highly effective in their focus territories ensures patients will receive the drug in as effective manner as possible,” said Thierry Volle, President EMEA, Lupin. “Lupin is committed to addressing the unmet needs of patients with NDM through the establishment of country-specific solutions and to ensuring patient access across Europe in alignment with national health authorities, healthcare providers and patient advocacy groups.”
Today, more than 7,500 people in Europe2,3,4 living with NDM have limited access to a licensed treatment for myotonia that can reduce the daily burden of this disabling, lifelong symptom. Limited access leads to inconsistent medication supply, administrative challenges and associated financial burdens, which, along with low awareness and limited clinical experience among healthcare professionals due to rare nature of disease, may result in significant harm to patients5. Lupin recently obtained approvals to begin a paediatric trial as part of the paediatric investigation plan for NaMuscla® and a post authorization [safety] study to address long-term safety and treatment efficaciousness on patient reported outcomes. Both trials will begin later this year.
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 1:100,0004), 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 across their lifetime. Patients perceive that myotonia increases in severity over time, impacting 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.
NaMuscla® is the first and only antimyotonic agent licensed to treat symptomatic myotonia in adults with non-dystrophic myotonic disorders across Europe. In randomized controlled trials, NaMuscla® (167 to 500 mg/day) has been shown to significantly reduce myotonia compared to placebo, reducing 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 well tolerated1.
