What are the key players in the Amyotrophic Lateral Sclerosis treatment market?

Overview of Amyotrophic Lateral Sclerosis (ALS)

Definition and Symptoms
Amyotrophic Lateral Sclerosis, commonly referred to as ALS or Lou Gehrig’s disease, is a fatal neurodegenerative disorder characterized by the progressive loss of motor neurons in the brain, brainstem, and spinal cord. Clinically, ALS leads to muscle weakness, difficulty with speech and swallowing, and ultimately respiratory failure. The hallmark features include both upper and lower motor neuron degeneration and a rapid progression that typically limits survival to two to five years from the onset of symptoms. Patients often experience initial focal muscle weakness that later disseminates gradually, resulting in paralysis and loss of voluntary movement. In addition to physical impairment, symptoms may include cognitive and behavioral changes in certain subsets of patients, which reflects the heterogeneous nature of the disease. The complexity and rapid progression of ALS underscore the urgent need for treatments that not only slow disease progression but ideally modify the underlying pathological process.

Current Treatment Landscape
Currently, the treatment landscape for ALS remains limited in terms of disease modification. Established therapies such as riluzole, which was approved decades ago, provide only modest survival benefits by reducing glutamate excitotoxicity, whereas edaravone works as a free-radical scavenger to modestly delay the progression of symptoms. More recently, combination therapy such as AMX0035 (sold as Relyvrio) has emerged, demonstrating statistically significant slowing in functional decline and some survival extension in clinical trials. Despite these approvals, the symptomatic and palliative nature of available treatments means that there is still considerable unmet medical need in terms of halting or reversing disease progression. Given an estimated prevalence of 4–7 per 100,000 people and the substantial economic and societal burden—ranging from high treatment costs up to $100,000–$200,000 per annum in advanced stages—the ALS treatment market is an area of intense research, which has stimulated the entry of large pharmaceutical companies as well as emerging biotech firms.
