amyotrophic lateral sclerosis (ALS)

amyotrophic lateral sclerosis (ALS)

ALS, also known as Lou Gehrig’s Disease, is a devastating progressive neurodegenerative disease that affects the motor nerve cells in the brain and the spinal cord of predominantly older people of both sexes. It is estimated that as many as 30,000 Americans may have the disease at any given time. The progressive degeneration of the motor neurons in ALS eventually leads to the death of the patient. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. When motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.

While non-invasive ventilation and gastrostomy tubes prolong life by 6-12 months, the average lifespan from time of symptom onset is 2-5 years. Currently, RILUTEK® is the only FDA-approved drug for ALS. RILUTEK is an NMDA receptor antagonist and has been shown to prolong life in patients with ALS by 3 months. Presently, there is no cure for ALS, nor is there a known cause.

RILUTEK® (riluzole) is a registered trademark of sanofi-aventis U.S. LLC.
