Myotonic Dystrophy: Understanding

Myotonic Dystrophy: Overview

Myotonic Dystrophy (DM) is considered a subgroup of myopathy and the most common type of muscular dystrophy that begins in adulthood. There are two major forms recognized based on clinical and molecular presentation: Myotonic dystrophy type I (DM1), known as Steinert disease, and myotonic dystrophy type II (DM2), or proximal myotonic myopathy which is a milder variety of DMI. These are progressive, multisystem genetic disorders.

Clinical presentation is diverse and can range from asymptomatic electrical myotonia to severe weakness and disability, including cardiac conduction defects, infertility, cataracts, and insulin resistance. A congenital form of DM type 1 is associated with an apparent developmental disability.

Myotonia is characterized by impaired relaxation of muscles after voluntary contraction due to repetitive depolarization of the muscle membrane. Myotonia, due to myotonic dystrophy, improves with repeated exercise and is worsened by exposure to cold. In 1992, the mutation responsible for DM1 was identified as a CTG expansion located in the 3' untranslated region of the dystrophia myotonica-protein kinase gene (DMPK).

The pathophysiology of DMI is related to the number of CTG repeats, with more repeats correlating with more severe disease. Those with less than 35 repeats are considered normal, and those that manifest with clinical symptoms typically have greater than 50. Maternal transmissions will often result in greater CTG expansion. Additionally, the newly expanded alleles have a bias for further expansions that leads to the genetic phenomenon of anticipation when transmitted from one generation to the next.

MDs are genetic disorders caused by localised mutations of DNA. Such DNA mutations result in a lack of dystrophin protein in DMD and an alteration of the protein production in DMs. No curative therapies are available to treat the pathogenic causes, and the identification of new therapeutic approaches to target genetic mutations is urgently needed. The most recent strategies to counteract MDs concern gene therapy and repurposing of drugs. Maximizing health and functional independence is the goal of supportive management. This is geared towards monitoring and treating all the medical issues associated with DM. Physical and occupational therapy is recommended for strengthening weakened muscles, evaluation for orthotics, and durable medical equipment needs. Speech-language pathology (SLP) is required for dysphagia and swallowing studies or dysarthria as indicated. SLP is also utilized for intellectual disabilities and learning strategies.

Myotonic Dystrophy Emerging Drugs Chapters

This segment of the Myotonic Dystrophy report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II/III, II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Myotonic Dystrophy Emerging Drugs

• Mexiletine: Lupin

Mexiletine, is developed by Lupin under names like Mexiletine hydrochloride and Namuscla, is a class Ib antiarrhythmic drug primarily used for treating muscle stiffness associated with myotonic dystrophy. As a sodium channel antagonist, mexiletine works by blocking voltage-gated sodium channels in skeletal muscle fibers. This prevents excessive sodium influx, which is responsible for the delayed muscle relaxation characteristic of myotonia. By stabilizing the cell membrane and reducing repetitive firing in hyperexcitable muscle cells, mexiletine effectively alleviates muscle stiffness and cramping, offering symptomatic relief for patients with myotonic dystrophy. Currently, the drug is in Phase III stage of its clinical trial for the treatment of myotonic dystrophy.

• Pitolisant: Harmony Biosciences

Pitolisant (WAKIX) is a selective histamine 3 (H3) receptor antagonist/inverse agonist. The mechanism of action of WAKIX is unclear; however, its efficacy could be mediated through its activity at H3 receptors, thereby increasing the synthesis and release of histamine, a wake promoting neurotransmitter. WAKIX was designed and developed by Bioprojet (France). Harmony has an exclusive license from Bioprojet to develop, manufacture and commercialize pitolisant in the United States. Currently the drug is being investigated in Phase II stage of Clinical trial evaluation for the treatment of Myotonic Dystrophy.

• ARO-DM1: Arrowhead Pharmaceuticals, Inc.

ARO-DM1 is an RNA interference (RNAi) conjugate designed to specifically silence DMPK mRNA in skeletal muscle. Published literature suggests that the silencing of aberrantly transcribed DMPK mRNA using ARO-DM1 may halt CUGexp-related spliceopathies in patients with DM1 leading to improved muscle strength and function. It belongs to a class of medicines called RNA therapeutics. The drug candidate is administered intravenously in the body. ARO-DM1 is currently in Phase I stage of development for the treatment of myotonic dystrophy.
