Roche's Game-Changing SMA Tablet Poised to Reshape Treatment Landscape
A simple tablet, barely larger than a pencil eraser, has just rewritten the playbook for one of the most devastating rare diseases affecting thousands globally. The European Commission approved Roche's new tablet formulation of Evrysdi for spinal muscular atrophy, marking a pivotal moment in the treatment of this progressive neuromuscular disorder.

"Freedom in a Tablet" – How Roche's Innovation Removes Critical Barriers
In the quiet homes of SMA patients across Europe, refrigerators have long housed lifelines – temperature-sensitive medications requiring careful preparation and administration. With yesterday's approval, that paradigm shifts dramatically.
The new 5mg tablet version of Evrysdi – approximately 6.5mm in size – eliminates the cold-chain requirements and reconstitution steps that have burdened patients and caregivers. It can be swallowed whole or dispersed in water, taken with or without food, and stored at room temperature.
"The logistics of managing SMA extend far beyond the medical appointments," explains Nicole Gusset, Chief Executive Officer of SMA Europe, who welcomed the development. "This is a disease requiring daily management, and it is paramount that people living with SMA, and those who care for them, are given options to optimize treatment administration."
Beyond Convenience: The Market Significance Hidden in Plain Sight
While seemingly a modest formulation change, market analysts suggest this development could expand Evrysdi's addressable market by approximately 15-20% and substantially reduce operational expenses related to logistics.
The tablet formulation particularly targets adult patients and emerging markets where cold-chain storage represents a significant barrier to treatment. Experts anticipate the tablet could capture roughly 30% of the existing European adult and adolescent patient pool in its first year alone, potentially adding about 4,000 new patients globally to the 18,000 already receiving the treatment.
"What looks like a simple CMC tweak actually represents a significant opportunity to reach previously underserved populations," notes a pharmaceutical industry analyst who requested anonymity. "Room-temperature stability simplifies everything from physician office storage to patient travel plans."
The bioequivalence data presented at SMA Europe's 4th Scientific International Congress in 2024 demonstrated that patients taking the tablet can expect the same established efficacy and safety as the original oral solution, allowing for immediate roll-out across EU27 countries without requiring new Phase 3 clinical trials.
The Competitive Battlefield in SMA Treatment
Evrysdi stands as the only non-invasive disease-modifying treatment for SMA in a competitive landscape that includes Biogen's Spinraza (administered intrathecally every four months) and Novartis's Zolgensma (a one-time gene therapy).
Spinraza generated approximately $1.7 billion in 2024 sales but faced a 4% year-over-year decline despite high-dose life-cycle management efforts. Zolgensma brought in roughly $1.2 billion, representing a steeper 14% decline amid payer pushback and manufacturing constraints.
The convenience advantage of Evrysdi's tablet formulation may further erode Spinraza's position, particularly in the adult segment where intrathecal administration presents challenges.
"The narrative around SMA treatment has evolved from 'can we treat it?' to 'how can we treat it most effectively with minimal disruption to daily life?'" explains a neurologist specializing in neuromuscular disorders. "A room-temperature tablet dramatically simplifies that equation for many patients."
Financial Implications: Modest for Roche, Meaningful for Patients
For Roche, the tablet formulation could translate to approximately CHF 130 million in incremental earnings before interest and taxes in 2025 – representing about 0.8% of the company's group EBIT. While relatively small for a pharmaceutical giant with a market capitalization of around $257 billion, the revenue stream comes with approximately 87% gross margins after accounting for royalties to PTC Therapeutics and Royalty Pharma.
Industry experts project Evrysdi sales could reach CHF 1.98 billion in 2025 (up from CHF 1.63 billion in 2024), with the new tablet formulation contributing about 7 percentage points of volume growth.
The company's stock currently trades at approximately 12.8 times enterprise value to EBITDA based on 2025 estimates, below the large-cap pharmaceutical peer average of 14.5 times, suggesting potential undervaluation if Evrysdi's growth trajectory accelerates.
The Road Ahead: Patent Protection and Pipeline Potential
Roche's core composition patents for Evrysdi extend to 2033, with follow-on formulation intellectual property potentially stretching exclusivity to 2038. This runway provides clear line-of-sight to return on investment for the incremental CMC spend on the tablet formulation.
Meanwhile, the company continues to advance GYM329, an anti-myostatin molecule targeting muscle growth, in combination with Evrysdi through the Phase II/III MANATEE clinical study for patients aged 2-10 years with SMA. Interim results are expected in the first half of 2026.
"The tablet strengthens physician loyalty ahead of potential GYM329 readouts," suggests a healthcare investor following the space. "It's a strategic move that reinforces Roche's commitment to the neuromuscular space while generating high-margin cash flows that offset biosimilar erosion in their oncology portfolio."
Investment Perspective: Underappreciated Growth Potential
Current consensus forecasts generally exclude meaningful Evrysdi growth beyond 2026 and ascribe zero value to the GYM329 combination therapy potential. This conservative modeling, coupled with Roche's discounted valuation relative to peers despite an improving product mix, suggests potential share price upside of 15-20% over the next 12-18 months.
The tablet approval comes at a strategically important time for Roche as the company navigates biosimilar competition to its oncology blockbusters Avastin and Herceptin. The high-margin rare disease revenue helps support the company's dividend and share repurchase programs.
Looking ahead, investors should monitor several key catalysts, including EU tablet launch metrics in Q3 2025, the potential U.S. FDA decision on the tablet formulation in Q4 2025, and the MANATEE interim analysis in the first half of 2026.
