Duchenne muscular dystrophy

Givinostat, a histone deacetylase (HDAC) inhibitor that impacts muscle fibrosis and inflammation in Duchenne muscular dystrophy, is now conditionally approved in Europe under the name Duvysat™. It concerns: DMD patients, aged 6 and over, ambulant, on corticosteroid therapy; and requires further efficacy results to be produced on ambulant patients. In the EPIDYS trial, the group … [Read more]

Chinese researchers wanted to know whether the long-term corticosteroid therapy used in Duchenne muscular dystrophy (DMD) could improve cardiac function: their work is based on a critical review of studies in the field published between 2000 and 2024, 21 studies were selected, 13 of which, corresponding to 1,814 DMD patients, argued in favour of a … [Read more]

British clinicians report the long-term results of a prophylactic treatment for cardiomyopathy in Duchenne muscular dystrophy (DMD): the combination of perindopril (a conversion enzyme inhibitor) and bisoprolol (a beta-blocker) had already been the focus of an initial randomised clinical trial by the same team in 2011 in children with DMD aged between 5 and 13 … [Read more]

Givinostat, a histone deacetylase (HDAC) inhibitor that acts on muscle fibrosis and inflammation in Duchenne muscular dystrophy, should be authorised in Europe very soon, under the name Duvysat™ (it has been authorised in the United States since March 2024). The application submitted to the EMA by the Italfarmaco laboratory was examined by the Committee for … [Read more]

A Chinese team has developed a rhesus monkey model of Duchenne muscular dystrophy, enabling it to evaluate a new gene therapy, with encouraging results. The DMDEx50 animal model has mutations in exon 50 of the DMD gene. A single-vector gene therapy called MyoAAV/Cas12iMax/sgRNA3Ex51 targeting exon 51 of the DMD gene was developed using Cas12iMax technology … [Read more]

Chinese researchers have revived a therapeutic technique designed to over-express utrophin, an endogenous protein very similar to dystrophin: they used a genome-editing approach in several models (cellular and animal) of Duchenne muscular dystrophy (DMD) combined with a Myo-AAV muscle-specific viral vector (to obtain MyoAAV-UA). after administration, robust and long-lasting overexpression of utrophin was obtained in … [Read more]

British researchers have succeeded in significantly improving the grafting of myogenic progenitor cells (MPC) into the muscle fibre of mouse models of Duchenne muscular dystrophy: they used a special gel (hydrogel) to stabilise the donor cells so that they would take better hold in the muscle of the recipient mice, Stem cells from patients suffering … [Read more]

The major challenge of exon skipping therapy in Duchenne muscular dystrophy is to effectively deliver the antisense oligonucleotides to the targeted tissues, in this case the muscles. After obtaining encouraging results over four weeks, a French team assessed the benefits of combining valproic acid with antisense oligonucleotides designed to skip exon 23 of the DMD … [Read more]

As treatment with delandistrogene moxeparvovec begins to be widely prescribed in the United States for Duchenne muscular dystrophy (DMD), American experts have come together to issue recommendations aimed at better identifying and preventing the deleterious effects of this gene therapy (GT) on the heart: cases of myocarditis induced by TG remain exceptional but can be … [Read more]

A group of international experts has drawn up international recommendations concerning the transition of patients with Duchenne muscular dystrophy (DMD) from paediatric to adult age: in real life, this pivotal period is often synonymous with loss of follow-up, which can be detrimental to the functional future of the DMD patient, Even though feedback varies from … [Read more]
