Discover groundbreaking treatments for Spinal Muscular Atrophy, offering hope and improved quality of life for patients and families. These innovative therapies target the genetic root of the disease, potentially halting its progression.

What is Spinal Muscular Atrophy?

Spinal muscular atrophy (SMA) is a rare genetic disorder that affects the nerve cells (neurons) in the spinal cord and brain. These neurons control muscle movement, and when they are damaged or lost, it leads to progressive muscle weakness and atrophy. SMA is caused by a mutation in the SMN1 gene, which is responsible for producing the survival motor neuron (SMN) protein. Without enough SMN protein, the neurons that control muscle movement deteriorate, leading to the symptoms of SMA.1

SMA is classified into several types based on the age of onset and severity of symptoms. The most common type is infantile SMA (type 1), which affects infants and is the most severe form of the disorder. Other types include intermediate SMA (type 2), juvenile SMA (type 3), and adult SMA (type 4). Each type has its own unique characteristics and progression.

SMA is a serious condition that can significantly impact a person’s quality of life. However, there have been significant advancements in the treatment of SMA in recent years, offering hope to individuals affected by this disorder.

Discover Treatment Options for Spinal Muscular Atrophy

Until recently, there were limited treatment options for SMA. However, the development of disease-modifying therapies has revolutionized the management of this condition. These therapies aim to increase the production of SMN protein or modify the splicing of the SMN2 gene to produce more functional SMN protein.

One such therapy is nusinersen (Spinraza®), an antisense oligonucleotide that increases the production of SMN protein. Nusinersen is administered intrathecally (into the spinal canal) and has shown promising results in improving motor function and survival in individuals with SMA. Another therapy is risdiplam (Evrysdi®), an oral medication that also increases SMN protein production. Risdiplam has demonstrated efficacy in improving motor function and respiratory outcomes in individuals with SMA.2

In addition to these therapies, gene therapy offers another potential treatment option for SMA. Zolgensma® (onasemnogene abeparvovec) is a one-time gene therapy that replaces the faulty SMN1 gene with a functional copy. Zolgensma has shown remarkable effectiveness in improving motor function and survival in infants with SMA type 1.

Spinal Muscular Atrophy Treatments: Hope and Progress

The development of these innovative treatments has brought renewed hope to individuals with SMA and their families. These therapies have the potential to significantly improve motor function, respiratory function, and overall quality of life. Early diagnosis and intervention are crucial for optimizing outcomes, and ongoing research continues to explore additional treatment strategies and potential cures for SMA.

The field of SMA research is rapidly evolving, with ongoing clinical trials and promising new therapies on the horizon. As research progresses, the outlook for individuals with SMA continues to improve, offering hope for a brighter future.
