Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Safety, Efficacy
Assess effect of three intra-arterial administrations of autologous MABs to the BB muscle on of m.3243A>G patients by assessing strength and fatigue in BB muscles of both arms before and after last MABs administration in left arm. Assess safety of the three ATMP administrations to the upper left arm by checking for SAEs, vascular obstructions and changes in neurological vital signs.
Secondary objectives 1
- Assess muscle mass in both BB muscles before and after treatment of left BB muscle. Assess morphology, m.3243A>G mutation load and mitochondrial respiratory capacity in muscle biopsies of the left BB muscle before the first and after the last MABs administration in left arm.
