Spinal Muscular Atrophy Treatment Market, Opportunity, Growth Drivers, Industry Trend Analysis and Forecast, 2024-2032

The global spinal muscular atrophy (SMA) treatments market was valued at USD 7.3 billion and is projected to grow at a CAGR of 19.1% from 2024-2032. Key drivers include the expansion of newborn screening programs, leading to earlier diagnoses and increased treatment eligibility. Early diagnosis enhances patient outcomes and boosts demand for neurological medications. Health Union, LLC reports that SMA affects 1 in every 6,000 to 10,000 newborns globally, with Type 1 SMA being the most severe and accounting for over half of all cases. Approximately 25,000 Americans currently live with SMA. Advancements in diagnostic technologies and increased awareness among healthcare providers and patients are anticipated to drive market growth.

The overall spinal muscular atrophy treatment industry is classified based on type, treatment type, route of administration, and region.

The global SMA treatment market is segmented by type into infant SMA, Werdnig-Hoffmann disease, adult SMA, and Kugelberg-Welander disease. The Werdnig-Hoffmann disease segment led the market with USD 2.9 billion in 2023. Mandatory newborn screenings have facilitated earlier detections, enabling prompt treatments that are most effective before significant motor neuron loss. This trend is set to drive market growth. Research and development, along with pharmaceutical collaborations to reduce treatment costs, have broadened patient access, further energizing market growth. Early access or compassionate use programs for SMA Type 1 treatment also bolster market momentum.

By treatment type, the market includes medication, supportive care, and spinal surgery. The medication segment, which includes antisense oligonucleotides, gene therapy, and other drugs, dominated with a 64.2% share in 2023. Innovative drugs like Spinraza (Nusinersen) and Evrysdi (Risdiplam) have transformed SMA treatment by targeting the genetic root and enhancing SMN protein production, driving market growth. The availability of both injectable and oral formulations has increased treatment accessibility, catering to diverse patient needs and preferences, thus fueling market growth.

North America, particularly the U.S., captured a significant 45.6% share of the global SMA treatment market in 2023 and is expected to maintain its dominance. Supportive policies for rare diseases, advanced healthcare facilities, and ongoing clinical trials are key factors driving market growth in the region. Additionally, the presence of leading pharmaceutical companies and increased funding for research and development are further bolstering the market. Rising awareness and early diagnosis of spinal muscular atrophy are also contributing to the expanding treatment landscape.
