SMA Treatment Market Driven by Rare Disease Awareness and Expanded Treatment Indications

The global SMA treatment market size was valued at US$ 4.40 billion in 2024 and is projected to reach US$ 13.09 billion by 2030, growing at a CAGR of 18.0% during the period 2025-2030.
SMA is a rare genetic neuromuscular disorder characterised by progressive loss of motor neurons leading to muscle weakness and atrophy. Treatment options include gene replacement therapies, SMN-protein-modulating drugs, and supportive care. Continued advances in diagnosis (including newborn screening), therapy approval, and early-intervention protocols are driving the market expansion.

Key Market Drivers

• Early diagnosis and newborn screening programmes: Earlier detection enables prompt treatment, improving outcomes and expanding treatable population.
  
  

• Breakthrough therapies and novel approvals: Gene replacement therapies, SMN-modulating drugs and other advanced treatments are driving market expansion.
  
  

• Increasing patient access and expansion into untreated populations: As therapy indications widen (e.g., for older patients or pre-symptomatic infants), market potential grows.
  
  

• Rising awareness and advocacy for rare diseases: Greater understanding of SMA among healthcare professionals, payers and patients supports market uptake.
  
  

Market Challenges

• High cost of treatment and reimbursement hurdles: Gene therapies and complex drugs are expensive, limiting access in many regions.
  
  

• Infrastructure and specialist-care requirements: Treatment often requires advanced delivery systems, specialist centres and long-term follow-up, which may be lacking in some geographies.
  
  

• Limited patient population and rare-disease complexity: As a rare condition, the market size is inherently limited and requires targeted strategies for growth.
