Global spinal muscular atrophy market size is estimated to be valued at USD 2,018.9 Mn in 2025 and is expected to exhibit a CAGR of 13.5% during the forecast period (2025-2032).
Spinal Muscular Atrophy (SMA) is characterized as a genetic condition with gradual muscle motor weakness as a result of loss of motor neurons, affecting firstly the muscles closest to the center of the body. The spinal muscular atrophy market growth is expanding rapidly with the introduction of new gene therapies like Zolgensma by Novartis, which has been approved by the FDA, and aims to treat the genetic cause of the disease. Broader diagnosis initiatives, growing concern, and favorable reimbursement policies are propelling growth in the SMA market. Active studies, along with increasing healthcare availability in developing areas, heighten overall growth, positioning SMA as a key focus in the therapeutics of rare diseases.

The Type 1 segment is expected to dominate the spinal muscular atrophy market with a commanding share of 57.2% in 2025. This dominance is primarily due to the severe nature and early onset of Type 1 SMA, also known as infantile-onset SMA, which necessitates immediate and intensive therapeutic intervention. The high prevalence and critical need for effective treatments in newborns and infants drive significant demand for advanced therapies targeting this segment.
Patients with Type 1 SMA experience rapid motor neuron degeneration leading to severe muscle weakness and respiratory complications, making early diagnosis and treatment crucial. Consequently, pharmaceutical advancements focusing on gene therapy, antisense oligonucleotides, and supportive care are predominantly tailored for this segment, fueling market growth.

The increasing prevalence of spinal muscular atrophy (SMA) is expected to drive the market growth over the forecast period. For instance, according to the Spinal Muscular Atrophy Foundation, a voluntary organization whose mission is to accelerate the development of a treatment for spinal muscular atrophy, SMA is believed to affect around 10,000 to 25,000 children and adults in the U.S., and therefore it is one of the most common rare diseases.
Increasing product launches are expected to drive the market growth over the forecast period. For instance, in June 2021, F. Hoffmann-La Roche Ltd, a multinational healthcare company, launched prescription medicine Evrysdi, indicated for the treatment of spinal muscular atrophy (SMA) in adults and children aged 2 months and older, in India.
The major factor that hinder growth of the global spinal muscular atrophy market include high cost of the treatment. For instance, according to an article published by MJH Life Sciences, largest privately held medical media company in the U.S., in March 2021, the mean per-patient annual direct medical cost was estimated to be between US$ 3,320 (spinal muscular atrophy type 3) in Italy and US$ 324,210 (type 1) in the U.S., with the variability high for other measures as well.
