Gathered online, facio-scapulo-humeral myopathy (FSH) experts from around the world shared and updated on the latest medical-scientific advances, both in the field of research and clinical trials.
The various presentations provided an opportunity to discuss in particular:
- the development of a new FSH mouse model: it can express very low levels of DUX4 under doxycycline,
- the identification of DUX4 inhibitors, such as matrin 3, which naturally blocks the expression of DUX4 and whose administration to a FSH cell model improves their viability and their myogenic differentiation and ARO-DUX4, an interfering RNAmacromolécule constituée d’une seule chaîne de nucléotides (simple brin) résultant de la transcription (copie) de l’ADN. which decreases the expression of DUX4 mRNAs, the injection of which improves the weight, muscle atrophy and muscle dysfunction of FSH model mice.
- the good safety of losmapimod, which is being evaluated in a phase IIAu cours d’un essai clinique de phase II, un médicament, dont il a été montré au préalable qu’il était bien toléré (au cours d’un essai de phase I) est administré à un groupe de malades dans le but de déterminer l’efficacité thérapeutique, les doses optimales et la sécurité du traitement (Quel est le mode d’administration et la dose maximale tolérée ?). La phase II peut être divisée en deux étapes : la phase IIa étudie le dosage et la phase IIb l’efficacité du traitement. placebo-controlled trial called ReDUX4, which involves 80 participants treated for one year. In contrast, the primary endpoint of the trial, a significant reduction in DUX4 gene expression under losmapimod, was not met. Fulcrum Therapeutics, which is developing the product, still reports improvements in muscle function and the quality of life of patients, as well as in fatty infiltration.
