Randomized Controlled Trial Multicenter Study
Safety, tolerability, and efficacy of subcutaneous efgartigimod in patients with chronic inflammatory demyelinating polyradiculoneuropathy (ADHERE): a multicentre, randomised-withdrawal, double-blind, placebo-controlled, phase 2 trial.
Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an autoimmune disease of the peripheral nervous system that can lead to severe disability from muscle weakness and sensory disturbances. Around a third of patients do not respond to currently available treatments, and many patients with a partial response have residual neurological impairment, highlighting the need for effective alternatives. Efgartigimod alfa, a human IgG1 antibody Fc fragment, has demonstrated efficacy and safety in patients with generalised myasthenia gravis. We evaluated the safety, tolerability, and efficacy of subcutaneous efgartigimod PH20 in adults with CIDP. ⋯ argenx.

Randomized Controlled Trial Comparative Study
Mexiletine versus lamotrigine in non-dystrophic myotonias: a randomised, double-blind, head-to-head, crossover, non-inferiority, phase 3 trial.
Non-dystrophic myotonias are skeletal muscle channelopathies caused by ion channel dysfunction. Symptom onset is frequently in the first decade of life, causing disability in a young cohort. Although there is no cure, symptomatic treatments exist. Previous trials provide evidence of the efficacy of mexiletine. More recently, lamotrigine has been shown to be effective. Both treatments have different profiles, including pharmacokinetics and adverse events. This trial aimed to investigate whether lamotrigine is non-inferior to mexiletine to directly inform clinical practice. ⋯ Neuromuscular Study Group, Jon Moulton Charity Trust, UCLH BRC Fast Track Grant.
