The global spinal muscular atrophy (SMA) treatment market is poised for significant growth, driven by the increasing prevalence of this genetic disorder, heightened awareness, and advancements in diagnostic and treatment technologies. In 2023, the SMA treatment market size was valued at approximately USD 5.67 billion, with projections indicating a remarkable compound annual growth rate (CAGR) of 23.2% during the forecast period from 2024 to 2032, potentially reaching USD 37.06 billion by 2032. This growth is attributed to several factors, including the rising number of SMA diagnoses, innovations in therapeutic approaches, and the expanded availability of healthcare services.
What is Spinal Muscular Atrophy (SMA)?
Spinal Muscular Atrophy (SMA) is a rare, hereditary neuromuscular disorder characterised by the progressive weakening of muscles, which occurs due to the degeneration of motor neurons in the spinal cord. This leads to muscle atrophy and impaired motor function. The severity of SMA varies, with types ranging from Type 1 (the most severe) to Type 4 (the mildest). Type 1 usually affects infants and toddlers, with patients often experiencing severe developmental delays and difficulty breathing. SMA Type 2 and Type 3 typically manifest in childhood, while Type 4 tends to develop in adulthood.
SMA is caused by mutations in the SMN1 (survival motor neuron 1) gene, which plays a critical role in the production of motor neuron proteins. The loss of SMN1 function leads to motor neuron death and muscle weakness.

Market Segmentation of the SMA Treatment Market
The global SMA treatment market can be segmented based on several factors:
- By Treatment Type:
- Gene Therapy: Gene therapies, such as Zolgensma, have revolutionised the SMA treatment landscape by addressing the root cause of the disease. These therapies aim to replace or restore the function of the SMN1 gene in patients.
- Antisense Oligonucleotide Therapy: Drugs like Spinraza (nusinersen) and Evrysdi (risdiplam) fall under this category. These therapies modify RNA to increase the production of the SMN protein, helping slow disease progression.
- Small Molecule Drugs: These are newer agents that aim to enhance the expression of the SMN1 gene, although they are still under investigation in clinical trials.
- By Disease Type:
- Type 1 SMA: The most severe form of the disease, requiring immediate intervention to prevent life-threatening complications.
- Type 2 and 3 SMA: These types are characterised by progressive motor impairment, with Type 3 being milder in its progression.
- Type 4 SMA: This form of SMA manifests later in life and has a less severe course.
- By End-User:
- Hospitals and Clinics: A major share of SMA treatments is administered in healthcare facilities, where patients can receive comprehensive care, including gene therapies and other interventions.
- Homecare Settings: Increasingly, with advancements in treatment and patient management, homecare settings are becoming more common, particularly for long-term SMA patients.
Key Market Players
Several key players dominate the SMA treatment market, each contributing to advancements in therapeutics and diagnostics:
- Novartis AG: A leader in gene therapy, Novartis’ Zolgensma is a ground-breaking treatment for SMA, particularly Type 1. Zolgensma is a one-time infusion therapy designed to replace the missing SMN1 gene.
- Biogen Inc.: Biogen’s Spinraza (nusinersen) is one of the first approved treatments for SMA. It works by increasing SMN protein production, alleviating symptoms and slowing disease progression.
- Roche Holdings AG: Roche’s Evrysdi (risdiplam) is an oral treatment for SMA that increases SMN protein production. It is designed for all SMA types, including types 1, 2, and 3.
- Sarepta Therapeutics: Sarepta is a key player with its focus on genetic therapies and antisense oligonucleotides. Their pipeline includes treatments targeting SMA and other rare diseases.
- Others: Additional market participants include Pfizer, Cure SMA, and several biotechnology companies exploring gene-based and RNA-based therapies for SMA.
Trends Shaping the SMA Treatment Market
Several trends are influencing the growth trajectory of the SMA treatment market:
- Advancements in Gene Therapy: The success of gene therapies, such as Zolgensma, has raised expectations for treatments targeting genetic disorders. As more genetic-based therapies are developed, the market is likely to experience a surge in new treatment options.
- Increased Diagnosis and Awareness: Greater awareness of SMA and advancements in genetic testing have led to earlier diagnoses, which allows for more effective intervention. With improved screening methods, more children are diagnosed with SMA, expanding the potential patient population for treatment.
- Insurance Coverage and Accessibility: As SMA treatments become more widely available, issues of insurance coverage and treatment affordability have gained attention. High-cost treatments like gene therapy face significant challenges in terms of reimbursement and coverage, which could impact their market penetration.
- Combination Therapies: The future of SMA treatment may involve a combination of therapies that target different aspects of the disease, including gene therapy, antisense oligonucleotides, and small molecules. This approach could improve overall outcomes for patients.
Market Outlook and Growth Potential
The SMA treatment market is set for rapid expansion. The market is expected to grow at a CAGR of 23.2% from 2024 to 2032, achieving a value of USD 37.06 billion by 2032. This growth is primarily driven by the increasing prevalence of SMA globally, advancements in gene therapies, and a growing number of treatment options for SMA patients.
- North America is expected to remain the largest market for SMA treatments due to the high incidence of SMA, advanced healthcare infrastructure, and strong presence of key market players.
- Europe is also a significant market, driven by a high standard of care and robust healthcare policies.
- Asia-Pacific is anticipated to witness the fastest growth during the forecast period, with improving healthcare systems, increasing awareness, and rising diagnosis rates in countries like China and India.
Impact of COVID-19 on the SMA Treatment Market
The COVID-19 pandemic disrupted healthcare services globally, including the treatment of rare diseases like SMA. Many elective surgeries and medical treatments were delayed, and in-person doctor visits were reduced, which impacted patient management. Clinical trials for SMA therapies also faced delays, slowing the introduction of new treatments. However, the pandemic highlighted the importance of telemedicine and remote patient management, which could continue to play a role in SMA treatment in the future.
Despite the challenges posed by the pandemic, the approval of critical therapies like Zolgensma and Spinraza continued, with many countries fast-tracking access to essential treatments for SMA patients. The need for innovative, long-term solutions for SMA care has become even more apparent in the post-pandemic world.
SMA Market Size and Share Analysis
