NMD Pharma Reports Results from the ESTABLISH Study – an International Observational Study of Neuromuscular Function in Charcot-Marie-Tooth Type 1 and 2

  • Results from the study establish, for the first time, neuromuscular junction (NMJ) transmission deficit as a new disease characteristic in patients with Charcot-Marie-Tooth (CMT) type 1 and 2

  • The level of NMJ transmission deficit in patients with CMT was associated with disease severity assessed through a range of clinical measurements of muscle strength and function

  • The ESTABLISH study provides reliability and tolerability estimates for a range of electrophysiological and clinical outcomes which will be key to selecting outcome measures for future clinical trials in CMT

Aarhus, Denmark, 20 June 2023 – NMD Pharma A/S, a clinical stage biotech company developing first-in-class, small molecule ClC-1 inhibitors for neuromuscular disorders, presented the results from ESTABLISH1, an observational study of neuromuscular function in patients with the inherited neurological conditions CMT types 1 and 2 in a poster presentation yesterday at the Peripheral Nerve Society Annual Meeting (PNS) being held in Copenhagen, Denmark.

Results from the study establish, for the first time, neuromuscular junction (NMJ) transmission deficit as a new disease characteristic in patients with Charcot-Marie-Tooth (CMT) type 1 and 2. The level of NMJ transmission deficit in patients with CMT was associated with disease severity assessed through a range of clinical measurements of muscle strength and function. The study also provides important information on tolerability and reliability of clinical and electrophysiological outcomes which will aid the selection of relevant outcomes in future clinical trials.

The study compared electrophysiological assessments (single fiber electromyography (EMG) and repetitive nerve stimulation) and clinical testing (involving tests of muscle strength, fatigability, dexterity, and balance) between 21 patients with CMT types 1 and 2 and 10 healthy age-matched subjects. The international study was led by Dr. Henning Andersen, Aarhus University Hospital, and Dr. William David Arnold, NextGen Precision Health, University of Missouri*.

Prof. Dr. Henning Andersen, Department of Neurology at Aarhus University Hospital commented:
CMT is a highly debilitating disease with no approved treatments to provide a cure or alleviate symptoms in patients. Here we show that patients with CMT are characterized by deficits of the neuromuscular junction to effectively transmit signals from nerves to muscles and that the level of transmission failure correlates with the functional capabilities of the patients. This opens the door for pharmacologically targeting the transmission failure to improve symptoms in patients with CMT.
