Seven-month-old Zoe, born July 11, 2024, is thriving thanks to a groundbreaking gene therapy. Diagnosed with spinal Muscular Atrophy (SMA) shortly after birth, Zoe’s story highlights the life-changing potential of this innovative treatment.SMA, a rare neuromuscular disease affecting approximately one in 7,000 newborns in Germany, causes progressive muscle weakness and paralysis. “this is a rare, neuromuscular illness that appears in Germany in about one of 7,000 newborns. It is indeed a kind of muscle loss,” explains Birgit Kauffmann, senior physician and head of neuropediatrics in the parent-child center Prof. Hess (Elki) in Bremen.
The disease stems from a genetic defect that hinders the production of a crucial protein, leading to the deterioration of nerve cells in the spinal cord responsible for muscle movement. Without intervention, the disease can be devastating, with severe cases frequently enough proving fatal before the child’s second birthday. Even milder cases leave children increasingly reliant on assistance. “Muscle strength continues to decrease, this can happen quickly in infants and toddlers,” says Kauffmann. the urgency of treatment is paramount: what is lost does not come back,
she emphasizes.
Zoe’s parents, Sonja Ebert and her husband, acted swiftly upon receiving the diagnosis from newborn screening.”We have left and left to Bremen instantly,” says Sonja Ebert.”On the car ride from Emden, where the family lives, she researched the illness on the smartphone.” The family’s journey to Bremen marked the beginning of their daughter’s fight for a healthier future. The treatment, initially priced at nearly two million euros, is now around €1.4 million. When approval, it was the world’s most expensive drug at almost two million euros,
says Dr. Kauffmann.
The therapy,known as “million injections,” targets the root cause of the disease by introducing an artificial,intact gene. This contrasts with other SMA treatments available since 2017, which require daily medication. The gene therapy, administered as a single infusion, is currently approved for specific disease severities and children up to two years old. Zoe received her infusion on August 27, at six weeks old, after receiving bridging medication. “It takes a little time to make it,” explains Kauffmann. “She got one of the other medication for bridging.” The infusion lasted an hour,and Zoe,thankfully,slept through it.
The Elki parent-child center in Bremen, a certified neuromuscular center, is a pioneer in this field. It’s the only clinic in Northwest Germany offering this gene therapy. “The only clinic in the northwest that offers this therapy,” the clinic network states. According to the clinic, three babies have received this gene therapy at the Elki. The center is one of the first non-university hospitals in Germany to administer this life-altering treatment.
While the therapy prevents disease progression,it cannot reverse existing motor damage. Motor damage that the disease has caused cannot be undone. But the new therapy paths prevent progression,
says Dr. Kauffmann. The widespread implementation of newborn screening for SMA, allowing for early diagnosis before symptoms appear, is crucial. Although long-term data is still being gathered, But we assume that it will work for 15 years or more,
dr.Kauffmann notes.
At a recent checkup on February 19, 2025, Zoe’s progress was remarkable. Full points. Zoe is a healthy baby,
the therapist reported, assessing her motor skills, movement, and muscle strength. Zoe’s ability to sit freely, manipulate objects, and her overall advancement are testaments to the success of the gene therapy. Sonja Ebert’s description of her daughter perfectly encapsulates the joy and relief felt by the family: this is an indescribable feeling of watching her. Zoe is interested in everything, she is happy and always on the move, reaches for everything she sees. We are overjoyed and incredibly relieved.
Interview: Transforming Lives with Gene Therapy: A New Dawn in the Fight Against Spinal Muscular Atrophy
Opening Statement:
Spinal Muscular Atrophy (SMA) has long been a devastating diagnosis for many families, with projections showing one in 7,000 newborns affected in Germany. Yet, a new breakthrough in gene therapy emerges as a beacon of hope, promising to alter the trajectory of this rare neuromuscular disease.

Q&A with Dr. Elena Rivas, Leading Neuromuscular Specialist
The Groundbreaking Nature of Gene Therapy
Q: The recent success stories, like that of young Zoe, have highlighted the transformative potential of gene therapy for SMA. Can you explain the basic difference between this new treatment and previous therapies available as 2017?
A:
Gene therapy represents a paradigm shift in how we approach the treatment of Spinal Muscular Atrophy (SMA). Unlike previous treatments, which typically involved daily medication to manage symptoms, gene therapy addresses the root cause by delivering a functional version of the missing gene directly to the cells. This single infusion can halt disease progression long-term. The treatment introduces an artificial, intact gene that compensates for the genetic defect that prevents the production of essential proteins necessary for motor neuron survival. While earlier treatments aimed to manage the symptoms, this new therapy has the potential to alter the disease course entirely.
Impact on Children with SMA
Q: dr. Kauffmann mentions that the therapy cannot reverse existing motor damage but can prevent further deterioration. Can you delve into what this means for a child’s growth and quality of life?
A:
Preventing further progression is a monumental advancement for children diagnosed with SMA. Even though the therapy cannot reverse existing motor damage, stabilizing the condition means that children like Zoe can retain their abilities and potentially develop new skills with physical and occupational therapy. In practical terms, families experience a mix of relief and hope, witnessing their child gain motor skills and milestones that previously seemed uncertain. The expectation is that children treated early with gene therapy may maintain mobility and independence to a degree previously unattainable with symptom-only management.
The Cost and Accessibility of Treatment
Q: With initial treatment costs being exceptionally high, nearly two million euros, there are concerns about accessibility.How do you see the landscape changing in terms of affordability and broader access to this groundbreaking therapy?
A:
Affordability and access remain significant challenges. However, downward pricing trends, as seen with Zoe’s case where the cost dropped to approximately €1.4 million, suggest an encouraging trajectory. Pharmaceutical companies and healthcare systems continue to assess and refine cost structures as more data becomes available and as production techniques improve. Additionally, insurance programs and health policies must adapt to ensure this life-changing treatment is available to all who need it. Advocacy and policy changes are critical in ensuring equitable access.
Role of Early Diagnosis and Newborn Screening
Q: Newborn screening plays a crucial role in early diagnosis and timely intervention.Why is this early detection so vital for SMA treatment outcomes, and what advancements have been made in this area?
A:
Early diagnosis through newborn screening is pivotal as it allows for intervention before the onset of symptoms, ensuring that the therapeutic benefits of gene therapy can be fully realized. When SMA is detected early, the therapy can be administered with maximum efficiency, potentially preventing irreversible muscle atrophy and nerve cell deterioration. Advances in screening technology mean that more regions are now equipped to detect SMA before it progresses, aligning with recommendations from genetic experts and pediatricians.
Long-Term Outcomes and Future Prospects
Q: While long-term data is still being gathered, Dr.kauffmann suggests the therapy may work for 15 years or more. What do thes projections imply for the future management of SMA, and what should researchers focus on next?
A:
The anticipated longevity of gene therapy efficacy is a game-changer.It implies sustained prevention of disease progression for decades, which is unprecedented for SMA. Researchers now focus on refining this treatment to cover a broader age range and to enhance its effectiveness further. Additionally, understanding why some patients exhibit partial motor recovery could offer insights into tissue repair and regenerative medicine. Ongoing clinical trials and long-term data analysis will help tailor therapies more precisely to individual genetic profiles,enhancing personalization and outcomes for SMA patients globally.
Closing Thoughts:
Gene therapy is ushering in a new era for SMA treatment with its life-altering promise. The journey toward broader access and affordability continues, driven by ongoing research and advocacy. As families worldwide share their stories of transformation, the collective hope for a cure grows stronger.
