FDA Approval of Dysport® for injection for the treatment of Lower Limb Spasticity in children aged two and older

A condition in which there is an abnormal increase in muscle tone or stiffness

Spasticity is a condition in which there is an abnormal increase in muscle tone or stiffness in one or more muscles, which might interfere with movement. Spasticity is usually caused by damage to nerve pathways in the brain or spinal cord that control muscle movement, and may occur in association with cerebral palsy, spinal cord injury, multiple sclerosis, stroke, and brain or head trauma.

Lower limb spasticity commonly involves spasticity in the gastrocnemius and soleus muscle complex located in the calf. These calf muscles are the chief extensors of the foot at the ankle-joint. In walking, they work to raise the heel from the ground.

Symptoms of spasticity may include increased muscle tone, rapid muscle contractions, exaggerated deep tendon reflexes, and/or muscle spasms. The degree of spasticity can vary from mild muscle stiffness to severe, painful, and uncontrollable muscle spasms.

 

A condition that greatly impacts children and their caregivers

“This approval in the US is a milestone in the treatment of pediatric lower limb spasticity, a condition that greatly impacts both children two years of age and older living with this form of spasticity and their caregivers. Dysport® is the first and only botulinum toxin approved by the FDA for this indication,” said Claude Bertrand, Executive Vice President, Research and Development, Chief Scientific Officer, Ipsen.

“The approval of abobotulinumtoxinA means that, for the first time in the USA, physicians have an FDA-approved botulinum toxin and recommended dosing and administration guidance for the treatment of children from two years of age and older with lower limb spasticity,” said Mauricio R. Delgado M.D., Professor of Neurology and Neurotherapeutics, University of Texas Southwestern Medical Center and the U.S. principal investigator of the Phase III trial.
