LEMS is a rare autoimmune disease that affects approximately 1 in 100,000 people in the United States. The most common symptoms of LEMS are proximal muscle weakness and fatigue. The symptoms can be life-threatening when the weakness is in the respiratory muscles. About 50% of LEMS patients have an underlying malignancy, typically small cell lung cancer.

"With 95% of rare diseases still having no FDA approved treatment, ongoing research and new products remain of vital importance to the rare disease community."
The presentation of the Firdapse NDA came as a result of the positive results of two phase 3 studies in which Firdapse-treated patients exhibited a rapid, significant and lasting improvement in muscle function, as well as a reduction in weakness and fatigability compared to patients receiving placebo.

About Lambert-Eaton Myasthenic Syndrome (LEMS)
LEMS, is a rare autoimmune disease, most often characterized by fatigable muscle weakness of the limb. The disease is caused by autoantibodies to voltage-gated calcium channels located in the nerve-muscle junction, resulting in poor nerve-muscle communication, leading to progressive muscle weakness, when they are not treated. In about 50% of cases, LEMS is associated with an underlying malignant tumor, most often small cell lung cancer, and in some individuals, LEMS is the first symptom of this tumor. LEMS usually affects the extremities, especially the legs. At the onset of the disease, the muscles closest to the trunk are affected, which makes it difficult to climb the stairs or to get up from a sitting position. Physical exercise and high temperatures tend to aggravate the symptoms. The weakness of the muscles of the mouth, throat and eyes is sometimes observed. People with LEMS may also have autonomic disruption, with symptoms of dry mouth, dry skin, constipation, blurred vision, impaired sweating, and / or inappropriate changes in blood pressure.
About Firdapse® (amifampridine)
Firdapse® (amifampridine) 10 mg tablet is an oral, nonspecific, voltage-dependent potassium channel blocker (K +) that causes depolarization of the presynaptic membrane and slows or inhibits repolarization. This action causes the opening of slow calcium channels (Ca2 +) depending on the voltage, allowing a subsequent influx of Ca2 +. In turn, it induces exocytosis of synaptic vesicles containing acetylcholine (ACh) to release more ACh in the synaptic cleft, which improves neuromuscular transmission and improves muscle function. Firdapse is approved in the United States and the European Union for use by patients with LEMS.
