Patient care and research in mitochondrial myopathies caused by thymidine kinase 2 (TK2) deficiency are currently advancing on several fronts, with the possible arrival of a first therapy in Europe for early-onset forms and improved monitoring of disease progression in late-onset forms.

For the 7 million people living with sickle cell disease worldwide, the authorisation granted by the French National Agency for Medicines and Health Products Safety (ANSM) to launch the DREPAMIR phase I/II clinical trial represents real hope. Supported by AFM-Téléthon and led by Professor Marina Cavazzana and Dr Anne Galy (ART-TG), the aim of this trial is to provide a long-term therapeutic solution for affected patients.
