Spinal Muscular Atrophy Treatment Market Report and Forecast 2025-2034

Spinal Muscular Atrophy Treatment Market Overview

Spinal muscular atrophy (SMA) treatment focuses on improving motor function, slowing disease progression, and enhancing quality of life. Therapies include gene replacement therapy, such as onasemnogene abeparvovec, which targets the genetic cause of SMA. Antisense oligonucleotide drugs, like nusinersen, enhance SMN protein production, improving nerve function. Risdiplam, an oral therapy, increases SMN protein levels systemically. Supportive care, including physiotherapy, respiratory support, and nutritional management, is crucial for patient well-being. Advances in gene therapy and personalised medicine continue to transform SMA treatment, offering improved prognosis and mobility for affected individuals.

Spinal Muscular Atrophy Treatment Market Growth Drivers

Increasing Adoption of Innovative Therapies to Drive Market Growth

The rising prevalence of spinal muscular atrophy and the increasing demand for advanced therapies are significant market drivers. Additionally, ongoing innovations in muscle-targeted therapies and enhanced treatment regimens are expected to fuel market growth. For instance, in October  2024, Scholar Rock announced promising results from the Phase 3 SAPPHIRE clinical trial evaluating apitegromab, an investigational muscle-targeted treatment for SMA. The therapy demonstrated a clinically significant improvement in motor function, offering a potential treatment option for SMA patients currently on standard care therapies. These positive results are poised to enhance treatment outcomes and drive market expansion in the forecast period.

Regulatory Advancements to Meet Rising Spinal Muscular Atrophy Treatment Market Demands 

The growing emphasis on early diagnosis and treatment of SMA alongside evolving therapeutic solutions is propelling the treatment market. For instance, In January  2025, Biogen Inc. revealed that both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) accepted applications for a higher dose regimen of nusinersen, which will offer a more rapid loading dose and extended maintenance dosing. This improved dosing regimen promises to optimise treatment efficacy, addressing unmet needs in SMA care and further expanding the therapeutic market. This development is anticipated to boost market growth in the coming years.

Spinal Muscular Atrophy Treatment Market Segmentation

Spinal Muscular Atrophy Treatment Market Share

Type 1 to Lead the Segmentation by Type

Type 1 spinal muscular atrophy (SMA) is the most severe and prevalent form, accounting for a significant portion of the spinal muscular atrophy patient population. Due to the urgent need for effective treatments, this segment is expected to hold the largest market share in the forecast period. Advances in gene therapies, such as Zolgensma, which specifically targets Type 1 SMA, are driving market growth. As these therapies offer life-changing benefits, the demand for treatments for Type 1 SMA will continue to increase. The success of Type 1 treatment options sets the tone for future growth in the treatment market.

Gene Replacement Therapy to Dominate Spinal Muscular Atrophy Treatment Market Segmentation by Procedure

Gene replacement therapy is poised to emerge as a leading procedure segment in the treatment market. The success of therapies like Zolgensma has made gene replacement a groundbreaking treatment option. By addressing the root cause of SMA, gene therapy provides long-term, transformative results compared to traditional drug therapies. With ongoing advancements in gene editing techniques and regulatory support, this segment is poised to dominate. The growing acceptance of gene therapies, along with their ability to offer permanent cures, is expected to propel this segment forward, driving significant market expansion in the coming years.

Parenteral Route to Hold a Major Spinal Muscular Atrophy Treatment Market Value by Route of Administration 

The parenteral route of administration, particularly intravenous (IV) injection or infusion, is amongst the commonly used methods for delivering spinal muscular atrophy treatments. With gene therapies like Zolgensma requiring intravenous infusion, this route of administration is likely to hold the largest market share in the forecast period. Parenteral delivery ensures optimal bioavailability, especially for biologic therapies that need to bypass the digestive system for effective absorption. The trend towards IV-based gene therapies, with their ability to provide targeted and long-lasting effects, will continue to drive the market for parenteral SMA treatments.

Hospitals to Lead the Spinal Muscular Atrophy Treatment Market by End User 

Hospitals are expected to lead the end-user segment for spinal muscular atrophy treatments due to the critical nature of SMA care and the specialised treatments required. These institutions are equipped with the necessary infrastructure, medical professionals, and facilities to administer complex therapies such as gene replacement and drug therapies. As SMA treatments become more advanced and require specialised monitoring and administration, hospitals are expected to maintain dominance in the market. With an increasing number of healthcare institutions adopting cutting-edge SMA therapies, hospitals are poised to drive the highest demand and expansion of SMA treatment solutions.

Spinal Muscular Atrophy Treatment Market Analysis by Region

The United States is likely to hold the largest market share in the market. This is primarily due to its well-established healthcare infrastructure, high awareness of SMA, and significant investment in biotechnology research. Additionally, the FDA's approval of innovative therapies such as gene therapy and RNA-based treatments has created a conducive environment for market growth. Europe, particularly Germany and the United Kingdom is also witnessing strong market expansion due to favourable reimbursement policies and increasing access to advanced therapies. Japan, with its robust healthcare system, is expected to show growth, while emerging markets like India are anticipated to contribute steadily with rising awareness and healthcare improvements.

Leading Players in the Spinal Muscular Atrophy Treatment Market

Other key players in the market include Cytokinetics Inc., PTC Therapeutics, Catalyst Pharmaceuticals, Astellas Pharma Inc., Pfizer Inc., and NMD Pharma A/S.
