About

The objective of this study is to evaluate the safety and pharmacokinetic of TAS-205 in patients with Duchenne Muscular Dystrophy.

Full description

Duchenne Muscular Dystrophy (DMD) is the most common fatal genetic disorder diagnosed in childhood, affecting approximately 1 in every 3500 lives male births. DMD patients suffer from a relentless decline in muscle strength that impairs the ability of walking and breathing, resulting in their lives with wheelchairs and loss of upper body function. The objective of this study is to evaluate the safety and pharmacokinetic of TAS-205 after single and multiple doses in DMD patients. It is also evaluated if TAS-205 affects the urinary excretion of pharmacodynamic (PD) marker in DMD patients.
