Duchenne Muscular Dystrophy (DMD) is a rare, life-limiting genetic disorder that primarily affects boys, leading to progressive muscle weakness and degeneration. The disorder has no cure, and the affected children typically lose the ability to walk by their early teens and experience life-threatening complications by the time they reach adulthood. As the world continues to see advances in medical science, there is growing hope for children with DMD, particularly through gene therapy. One of the most promising treatments in this field is Elevidys, a gene therapy designed to treat DMD by addressing the root cause of the disorder.
In Brazil, however, there is a significant barrier that limits the potential life-saving benefits of Elevidys: the age restriction for its administration. Currently, the Brazilian National Health Surveillance Agency (ANVISA) permits the use of Elevidys only for children aged 7 or younger, leaving many children who could benefit from the therapy ineligible. In this article, we will explore why this age limit should be rescinded immediately, and why all Brazilian children with DMD, regardless of their age, should have access to Elevidys gene therapy.

Understanding Elevidys Gene Therapy
Elevidys is an advanced form of gene therapy that aims to restore the production of dystrophin, a protein that is essential for muscle function but is absent in individuals with DMD. This innovative treatment works by delivering a functional copy of the dystrophin gene into muscle cells, allowing them to produce the dystrophin protein. As a result, the therapy has the potential to halt or even reverse the progressive muscle weakness characteristic of DMD. [Read More: Frequently Asked Questions About Elevidys]
While clinical trials of Elevidys have primarily focused on younger children, the therapy has shown promise in halting the disease’s progression when administered early. This is why it is crucial that all children with DMD have access to it—no matter their age. Early intervention is critical to preventing irreversible muscle damage and maximizing the benefits of gene therapy.
The Current Age Limit: A Barrier to Life-Saving Treatment
The decision by ANVISA and the Brazilian government to restrict Elevidys to children 7 years and younger has drawn considerable concern from families, healthcare professionals, and advocates for DMD research. The rationale behind this age limit stems from clinical trials and data collected primarily from younger participants. While it is understandable that treatment protocols and approvals are often based on scientific studies, the age cutoff does not reflect the reality of the disease and the potential benefits of the therapy for older children.

DMD is a progressive disorder, and as the disease progresses, muscle deterioration accelerates. By the time a child reaches the age of 8, 9, or 10, they may already have suffered significant muscle loss and functional impairment. Restricting access to Elevidys based on age, rather than disease progression, effectively condemns these children to a future of irreversible muscle damage, loss of mobility, and a reduced quality of life.
Why the Age Limit Should Be Rescinded
Duchenne Muscular Dystrophy Does Not Follow an Age-Only Timeline
DMD is a highly individualized disease, and its progression is influenced by factors such as the child’s baseline health, the severity of their condition, and the timing of medical interventions. While younger children tend to benefit most from gene therapy, this does not mean that older children cannot still experience meaningful improvements in their condition. In fact, there are increasing indications that even those who are slightly older could see a reduction in disease progression, if not an outright reversal of some effects of the condition, if treated with Elevidys in time.
Delay in Treatment Leads to Irreversible Damage
The impact of delaying or denying gene therapy is significant. The progressive nature of DMD means that the longer a child is left untreated, the more damage is done to their muscles. Once muscle fibers degenerate, they do not regenerate, leading to irreversible muscle loss. As children age, their functional abilities decline sharply, and they may lose the ability to walk, breathe independently, or perform basic daily activities.
If Elevidys were available to all children with DMD, including those over the age of 7, many of these children would benefit from a reduction in disease progression and an improvement in their overall health. The therapy could preserve mobility and reduce the need for long-term care, which would not only enhance the child’s quality of life but also reduce the overall healthcare burden.
The Science Is Evolving
Gene therapy is a rapidly advancing field, and the data supporting its use continues to grow. While initial studies of Elevidys focused on younger children, there is an increasing body of evidence suggesting that older children and even adults with DMD could still benefit from gene therapy. Ongoing research and case studies are showing positive outcomes in patients treated later in the course of their disease, and therefore, the age cutoff should be reevaluated based on the latest scientific data.
Ethical Considerations: Denying Hope to Children
From an ethical standpoint, denying access to Elevidys based on age is not only scientifically unjustifiable but also deeply unfair to families. These children are in desperate need of treatment, and limiting access based on a single factor—age—risks depriving them of the chance to live a better, longer life. The decision to restrict access based on age alone does not take into account the human element—the children who could benefit from this treatment and the families who are hoping for a breakthrough that could give their children the chance for a better future.

The Call for Immediate Action
We are calling on ANVISA and the Brazilian government to immediately rescind the age limit of 7 for Elevidys gene therapy. The current policy is not only out of step with the latest scientific understanding of DMD and gene therapy, but it is also denying Brazilian children the opportunity to benefit from a treatment that could dramatically alter the trajectory of their lives. Every child with Duchenne Muscular Dystrophy, regardless of age, deserves a chance to receive this groundbreaking treatment.
By removing the age limit, we can ensure that no child is left behind in the fight against DMD. We are calling on policymakers, healthcare providers, and the broader community to stand with families affected by this devastating disease and advocate for the immediate availability of Elevidys for all children with Duchenne Muscular Dystrophy.
Conclusion
Duchenne Muscular Dystrophy is a devastating diagnosis for families, and the need for effective treatments is urgent. Elevidys gene therapy offers a glimmer of hope, but that hope should not be restricted based on arbitrary age limits. The time has come for Brazil to reassess its stance and ensure that every child, regardless of age, has access to this life-changing therapy. It is time to put the health and well-being of children first and make sure that every Brazilian child with Duchenne Muscular Dystrophy has the opportunity to receive Elevidys gene therapy, as soon as they are diagnosed, no matter their age.
