Bridging the Gap: Addressing Unmet Needs in Spinal Muscular Atrophy for Older Patients

Panelists discuss how spinal muscular atrophy (SMA) progresses over time, affecting motor function differently in older patients vs infants, with experts noting the shift from traditional classification (types 1 to 4) to functional categories (nonsitters, sitters, walkers).

Panelists discuss how the needs of older patients with spinal muscular atrophy (SMA) differ from infants, focusing on independence, education, career goals, fatigue management, and quality of life rather than just motor milestones.

Early intervention in Spinal Muscular Atrophy is crucial for better outcomes, emphasizing the need for timely treatment to prevent irreversible disability.

Untreated Spinal Muscular Atrophy leads to severe complications and declines in quality of life, emphasizing the need for early intervention.

Panelists discuss how supportive care for patients with spinal muscular atrophy (SMA) includes rehabilitation, respiratory care, psychosocial support, and multidisciplinary approaches to help patients achieve independence and improved quality of life.

Panelists discuss how the current spinal muscular atrophy (SMA) treatment landscape includes 3 options: gene therapy (onasemnogene abeparvovec [Zolgensma]) for younger patients and 2 splice modifiers (nusinersen [Spinraza] and risdiplam [Evrysdi]) for older patients.

Panelists discuss how splice modifiers work by enhancing protein production from the SMN2 gene, with risdiplam (Evrysdi) being an oral daily medication and nusinersen (Spinraza) being administered intrathecally quarterly, both showing similar safety and efficacy profiles.

Panelists discuss how disease progression despite treatment in older patients with spinal muscular atrophy (SMA) may be due to natural aging effects combined with SMA, not necessarily treatment failure, highlighting the importance of exercise, nutrition, and management of contractures.

Panelists discuss how comorbidities such as scoliosis, dislocated hips, and nutritional issues affect spinal muscular atrophy (SMA) treatment decisions, with treatment approaches evolving as patients' functional abilities improve with disease-modifying therapies.

Panelists discuss how emerging intrathecal gene therapy for older patients with spinal muscular atrophy (SMA) shows modest efficacy with fewer systemic adverse effects than intravenous administration, though safety concerns and limited data remain.

Panelists discuss how combination therapies targeting different aspects of spinal muscular atrophy (SMA), such as myostatin inhibitors (targeting muscle) alongside SMN protein-enhancing treatments, hold promise for addressing fatigue and improving muscle function in older patients.

Panelists discuss how insurance challenges impact spinal muscular atrophy (SMA) care, with prior authorizations becoming more streamlined over time but limitations on physical therapy sessions and inequitable access to treatments remain significant barriers.

Panelists discuss how communication between clinicians, patients, and payers could improve equitable access to spinal muscular atrophy (SMA) treatments, while acknowledging the complex value assessment of high-cost therapies vs improved quality and length of life.

Panelists discuss how spinal muscular atrophy (SMA) treatment will evolve over the next 5 years, likely incorporating improved gene therapy delivery systems, combination therapies, and rehabilitation models, while maintaining individualized approaches for each patient.
