The majority of SMA cases are caused by the deletion of a portion of the <strong>SMN1<\/strong> gene, which impairs the production of the essential SMN protein.<\/p>\n\n\n\n<p>As a rare genetic condition, <a href=\"https:\/\/www.delveinsight.com\/report-store\/spinal-muscular-atrophy-sma-epidemiology-forecast\">spinal muscular atrophy incidence<\/a> is best described in terms of birth prevalence\u2014that is, the number of children born with the disorder over a specific time frame. The classical forms of SMA arise from mutations in both copies of the <strong>SMN1<\/strong> gene, located on chromosome 5, leading to a significant deficiency of SMN protein.&nbsp;<\/p>\n\n\n\n<p>Another gene, <strong>SMN2<\/strong>, also contributes to SMN protein production; however, the protein it generates is usually incomplete, and only about <strong>10% to 20%<\/strong> of it is functional. It is estimated that around <strong>60%<\/strong> of infants diagnosed with SMA have type I, the most severe form, while types II and III account for the remaining <strong>40%<\/strong>.<\/p>\n\n\n\n<p>There is currently no definitive cure for spinal muscular atrophy. Spinal muscular atrophy treatment focuses on symptom management and complication prevention.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-fda-approved-therapies-for-spinal-muscular-atrophy-treatment-nbsp\"><span class=\"ez-toc-section\" id=\"FDA-Approved_Therapies_for_Spinal_Muscular_Atrophy_Treatment\"><\/span><strong>FDA-Approved Therapies for Spinal Muscular Atrophy Treatment&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The approval of three <a href=\"https:\/\/www.delveinsight.com\/report-store\/spinal-muscular-atrophy-market-insights-epidemiology-and-market-forecast\">treatments for spinal muscular atrophy<\/a>, namely, <strong>SPINRAZA (Ionis\/Biogen), EVRYSDI (Roche)<\/strong>, and the groundbreaking gene therapy <strong>ZOLGENSMA (Novartis)<\/strong>, has significantly addressed several unmet needs, offering patients more personalized therapeutic options. Still, managing SMA effectively goes beyond these medications. It requires a robust, multidisciplinary approach that encompasses supportive care to reduce complications and improve quality of life for both patients and their families. This integrative care model includes input from neurology, physical therapy, nutrition, and other specialties to support long-term outcomes.<\/p>\n\n\n\n<p>While symptomatic treatments are available, a comprehensive management plan also emphasizes key areas such as nutritional support, respiratory evaluation, respiratory muscle care, orthopedic interventions, rehabilitation, and select off-label medications\u2014all contributing to a well-rounded care strategy for SMA patients.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.delveinsight.com\/report-store\/zolgensma-onasemnogene-abeparvovec-xioi-drug-insight-market-forecast\">ZOLGENSMA<\/a>, developed by AveXis, a Novartis company, has received FDA approval as a one-time gene therapy for children under 2 years of age with SMA. It works by targeting the root genetic cause\u2014replacing the function of the missing or faulty SMN1 gene to halt disease progression. Delivered through a single infusion, ZOLGENSMA introduces a functional SMN gene to motor neuron cells, helping maintain muscle function.<\/p>\n\n\n\n<p>The therapy uses a vector derived from AAV9, which is not known to cause illness. Before administering ZOLGENSMA, physicians must check that the child\u2019s AAV9 antibody levels are within an acceptable range via a blood test to ensure effective gene therapy delivery.<\/p>\n\n\n\n<p>SPINRAZA enhances SMN protein production by using an antisense oligonucleotide to modify the splicing of the SMN2 gene. EVRYSDI, a small molecule, also promotes functional SMN protein production by influencing SMN2 splicing.<\/p>\n\n\n\n<p>Of the three FDA-approved spinal muscular atrophy treatments, SPINRAZA and ZOLGENSMA have emerged as blockbuster therapies, with SPINRAZA securing a major portion of the market across the 7MM. These innovative spinal muscular atrophy drugs have revolutionized the spinal muscular atrophy treatment and generated substantial revenues for the companies behind them.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.delveinsight.com\/sample-request\/spinal-muscular-atrophy-market-insights-epidemiology-and-market-forecast\"><img decoding=\"async\" width=\"1024\" height=\"506\" src=\"https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-1024x506.png\" alt=\"Emerging Spinal Muscular Atrophy Therapies\" class=\"wp-image-32233\" srcset=\"https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-1024x506.png 1024w, https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-300x148.png 300w, https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-150x74.png 150w, https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-768x379.png 768w, https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-1536x758.png 1536w, https:\/\/assets.delveinsight.com\/blog\/wp-content\/uploads\/2025\/05\/19161310\/Emerging-Spinal-Muscular-Atrophy-Therapies-2048x1011.png 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-spinal-muscular-atrophy-pipeline-therapies-the-race-for-a-cure\"><span class=\"ez-toc-section\" id=\"Spinal_Muscular_Atrophy_Pipeline_Therapies_The_Race_for_a_Cure\"><\/span><strong>Spinal Muscular Atrophy Pipeline Therapies: The Race for a Cure<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Since 2016, the FDA has approved three treatments that modify the course of spinal muscular atrophy, marking a major shift in managing the disease.
