Randomized Controlled Trial Multicenter Study
Safety and efficacy of daridorexant in patients with insomnia disorder: results from two multicentre, randomised, double-blind, placebo-controlled, phase 3 trials.
Daytime functioning is impaired in people with insomnia disorder. Currently available dual orexin receptor antagonists have shown efficacy in insomnia disorder, but do not address all aspects of this disease. We aimed to assess safety and efficacy of daridorexant, a novel orexin receptor antagonist, on night-time and daytime symptoms of insomnia. ⋯ Idorsia Pharmaceuticals.

Review
Advances and ongoing research in the treatment of autoimmune neuromuscular junction disorders.
Myasthenia gravis and Lambert-Eaton myasthenic syndrome are antibody-mediated autoimmune diseases of the neuromuscular junction that usually present with weakness in ocular muscles and in proximal muscles of the limb and trunk. Prognosis regarding muscle strength, functional abilities, quality of life, and survival is generally good. However, some patients do not respond to treatment. ⋯ In the past few years, new biological agents against complement, the FcRn receptor, or B-cell antigens have been tested in clinical trials. These new therapies extend the possibilities for targeted immunotherapies and promise exciting new options with a relatively rapid mode of action. Challenges in their use might occur, with barriers due to an increase in cost of care and additional considerations in the choice of drugs, and potential consequences of infection and vaccination due to the COVID-19 pandemic.

Autoimmune neuromuscular junction disorders are rare. However, myasthenia gravis is being increasingly recognised in people older than 50 years. In the past 5-10 years, epidemiological studies worldwide suggest an incidence of acetylcholine receptor antibody-positive myasthenia gravis of up to 29 cases per 1 million people per year. ⋯ The course of disease can be followed up with internationally accepted clinical scores or patient-reported outcome measures. For prognostic purposes, determining whether the disease is paraneoplastic is of great importance, as myasthenia gravis can be associated with thymoma and Lambert-Eaton myasthenic syndrome with small-cell lung cancer. However, despite well defined diagnostic parameters to classify patients into subgroups, objective biomarkers for use in the clinic or in clinical trials to predict the course of myasthenia gravis and Lambert-Eaton myasthenic syndrome are needed.
