Drugs in development or marketed with the support of AFM-Telethon concern neurological and neuromuscular diseases, diseases of the liver, vision, skin and immune system.

The table of drugs developed with the support of AFM-Telethon

AFM-Telethon has supported and continues to support the development (clinical trials underway or in preparation) of over forty drugs in gene therapy, cell therapy and pharmacology. Almost half of them concern neuromuscular diseases, the other concern rare diseases. 

Some are already available for patients, and others are still in development.

  • The preclinical development of a gene therapy by another type of candidate drug (morpholino antisense oligonucleotides) for the exon 53 skipping enable the launch of a phase I/II human clinical trial, the SRP-4053 trial (Skip-NMD) whose results have been published. 
  • Phase III tamoxifen trial. This drug, used in oncology for almost 40 years, is assessed in Duchenne muscular dystrophy, following preclinical studies supported by the AFM-Telethon. A phase III clinical trial underway, the TAMDMD trial, in France, Germany, Spain, the Netherlands and the United Kingdom. Find out more.

  • A preclinical development of a pediatric form of a molecule to combat muscular atrophy, BIO 101 or Sarconeos, is underway, prior to a clinical trial that could start in 2020, depending on regulatory authorizations. Find out more. 

Limb girdle muscular dystrophy 

  • Calpain-related R1 limb girdle muscular dystrophy (ex-LGMD2A) or calpainopathy. The preclinical development of an AAV vector carrying a normal copy of the CAPN3 gene for use in gene therapy is underway at Genethon. Find out more. 
  • Alpha-sarcoglycan-related R3 limb girdle muscular dystrophy (ex-LGMD2D) or Alpha-sarcoglycanopathy. A preclinical study aims to assess the effects of givinostat in an animal model prior to a potential human clinical trial. This molecule, by acting on follistatin, promotes increased muscle mass and limits fibrosis and inflammation of the muscle.

    • The preclinical development of an AAV vector carrying a normal copy of the SGCG gene (gene therapy) us underway at Genethon. Find out more.
    • Preclinical studies to assess the effects of givinostat in an animal model prior to a potential human clinical trial. Givinostat acts via the follistatin gene by limiting fibrosis and inflammation of the muscle and promoting muscle regeneration,  
  • FKRP-related R9 limb girdle muscular dystrophy (ex-LGMD2I). Genethon developped a gene therapy using an AAV vector carrying a normal copy of the FKRP gene. A natural history study of this form of LGMD is underway. In 2022, it was granted authorization to start a phaseI/II gene therapy clinical trial in France, Denmark and the UK.
