These factors are contributing significantly to the growth of the spinal muscular atrophy treatment industry.

The gene therapy segment is projected to grow at a significant CAGR over the forecast period due to its life-changing impact on spinal muscular atrophy treatment. The advent of gene therapies has opened new frontiers in patient care, offering potential cures rather than just symptomatic relief. As more gene therapy options become available and clinical data supporting their efficacy continues to accumulate, healthcare providers are likely to adopt these innovative treatments more readily. This shift toward genetic interventions is expected to enhance patient outcomes and drive market growth significantly.

Route of Administration Insights

The injection segment dominated the market with the largest revenue share in 2024, driven by its established efficacy and rapid delivery of therapeutic agents directly into the bloodstream. Injectable treatments are often preferred for their ability to provide immediate effects, particularly in critical cases of spinal muscular atrophy where timely intervention is essential. Moreover, advancements in injection technologies have improved patient compliance and comfort, further solidifying injection segment dominance in spinal muscular atrophy treatment.

The oral segment is anticipated to grow at the highest CAGR over the forecast period, which can be attributed to increasing patient preference for non-invasive administration methods. Oral medications offer convenience and ease of use compared to injections, making them particularly appealing for long-term management of chronic conditions. As pharmaceutical companies focus on developing effective oral formulations that maintain therapeutic efficacy, this segment is expected to gain traction among patients and healthcare providers.
