Following several proofs of concept, Atamyo Therapeutics, a spin-off from Geenethon, has obtained authorisation to start a new gene therapy trial in patients suffering from limb-girdle muscular dystrophy (LGMD) R5 linked to SGCG (gamma-sarcoglycanopathy). Its aim is to test the safety, pharmacodynamics and efficacy of ATA-200, a product resulting from the work of Isabelle Richard, a researcher at Genethon. Approved to take place in France (at I-motion) and Italy, this new multicentre phase IAu cours d’un essai clinique de phase I un médicament dont l’intérêt thérapeutique a été montré sur des modèles animaux et/ou cellulaires (essais précliniques) est administré pour la première fois à un petit groupe de volontaires sains, plus rarement à des malades, afin d’évaluer leur tolérance à la substance en fonction de la dose (Comment le futur traitement est-il absorbé et éliminé ? Comment se fait sa répartition dans les organes ? Est-il toxique et à quelles doses ? Existe-t-il des effets secondaires ?)./II trial will include :
- six walking children aged between 6 and 12 with a clinically and genetically confirmed diagnosis of LGMD R5 ;
- two cohorts, each receiving a single intravenous injection of ATA-200, the first at 1 x 1014 vg/Kg and the second at a dose three times higher;
- an assessment of the effects of the product at six months;
- follow-up of patients for four and a half years after the evaluation phase.
Recruitment is due to begin in May this year, with the first injections scheduled for the third quarter of 2024.
