Some people with Lambert–Eaton myasthenic syndrome (LEMS) experience a phenomenon called postexercise facilitation of reflexes, where normal reflexes are initially absent but then briefly return after a muscle is flexed. The case of a man who was diagnosed with LEMS after doctors noted postexercise facilitation of reflexes was…

Firdapse (amifampridine), an approved oral treatment for Lambert-Eaton myasthenic syndrome (LEMS), is now available to people in Japan with the rare autoimmune disease. The therapy, available in the form of 10 mg tablets, was launched by Dydo Pharma. Dydo is responsible for the development and commercialization…

Anti-CD19 CAR T-cell therapy was found to be effective in treating a 54-year-old man with Lambert-Eaton myasthenic syndrome (LEMS) who wasn’t responding to other immune-suppressing and symptomatic treatments, according to a case report from researchers in Germany. The team’s observations suggest that this type of cell therapy may be…

Firdapse (amifampridine) can help ease symptoms of Lambert-Eaton myasthenic syndrome (LEMS) in patients who don’t have an underlying cancer and its efficacy is consistent regardless of how long a delay there is before it’s started. That’s according to a study, “Safety, efficacy and steroid-sparing…

The rare case of a man with lung cancer complicated by two co-occurring cancer-associated syndromes — Lambert-Eaton myasthenic syndrome (LEMS) and syndrome of inappropriate antidiuretic hormone secretion (SIADH) — was described in a recent report. According to its scientists, only four other documented reports of LEMS and SIADH developing…

DyDo Pharma is seeking approval of Firdapse (amifampridine) to treat Lambert-Eaton myasthenic syndrome (LEMS) in Japan. A decision from Japan’s Pharmaceuticals and Medical Devices Agency is expected in September. DyDo’s application was submitted in collaboration with Catalyst Pharmaceuticals, which developed Firdapse. DyDo is leading the development…

The rare case of a man with Lambert-Eaton myasthenia syndrome (LEMS) that co-occurred with non-Hodgkin lymphoma, a type of immune cell cancer, was described in a recent report. “In this case report, we present the case of a 57-year-old male diagnosed with non-Hodgkin’s lymphoma (NHL) who developed LEMS, an…

In the first documented case of its kind, spontaneous cancer regression was seen in a man in Japan with Lambert-Eaton myasthenic syndrome (LEMS) associated with lung cancer. Given that cancer-associated LEMS is thought to be triggered by the immune system attacking cancer cells, scientists believe such a LEMS-driving immune…

Lambert-Eaton myasthenic syndrome (LEMS) may be underdiagnosed in a sizeable fraction of people with small cell lung cancer (SCLC), a study analyzing real-world data suggests. Based on these findings, scientists argue that standardized protocols to screen people with SCLC for LEMS “may be warranted.” David Morrell, senior vice president…

Using digital tools to measure changes in gait and other aspects of physical activity outside of a hospital setting is a promising avenue for research in rare neurological disorders like Lambert-Eaton myasthenic syndrome (LEMS) — but more research is needed to validate these tools for use in studies. That’s…
