Tolebrutinib Sales Forecast, and Market Size Analysis - 2034

Key Factors Driving Tolebrutinib Growth

1. Market Share Gains and New Patient Starts

• Tolebrutinib is positioned to become the first oral BTK therapy for progressive forms of multiple sclerosis (MS) if approved, giving it potential to capture meaningful share in an area with few disease-modifying options.
• Commercial uptake expectations are strong among neurologists because the HERCULES Phase III data showed benefit on disability progression - a key unmet need in non-relapsing secondary progressive MS (nrSPMS).
• Sanofi's global launch planning and physician engagement (neurology KOL outreach, specialist center focus) are being mobilized to support rapid adoption in eligible progressive-MS populations pending regulatory approvals.

2. Expansion Across Key Indications

• Non-relapsing Secondary Progressive MS (nrSPMS): The lead near-term commercial target - HERCULES Phase III demonstrated a clinically meaningful reduction in confirmed disability progression, directly addressing a major unmet need.
• Primary Progressive MS (PPMS): The PERSEUS Phase III program is ongoing with results expected in H2 2025, which could extend the label into primary progressive disease if positive.
• Relapsing MS (RMS): Earlier GEMINI trials had mixed results (some relapsing MS trials missed primary endpoints), so RMS positioning is uncertain and will depend on pooled analyses and regulatory discussions.
• Broader neuroinflammation applications (future potential): If the BTK mechanism shows durable benefit and acceptable safety, Sanofi may explore additional neurodegenerative or neuroinflammatory indications where microglial modulation is relevant.

3. Geographic Expansion

• Sanofi is preparing global regulatory and launch pathways (US priority review accepted; filings/registrations in EU, Japan and other markets anticipated), aiming for multi-region commercialization once approvals are secured.
• Early regulatory and market activity (including approval in some smaller jurisdictions reported later in 2025) will drive staged geographic expansion; major commercial focus will be the US, EU and Japan where progressive-MS treatment demand is highest.
• Sanofi is lining up manufacturing and specialist distribution channels to support access in high-volume neurology centers and tertiary MS clinics.

4. New Indication Approvals (Regulatory Status / Expectations)

• Tolebrutinib's NDA for nrSPMS was accepted and given priority review; HERCULES Phase III results were published in NEJM and formed the basis for regulatory filings. As of Sept 22, 2025, the FDA has extended its target action date by three months (review ongoing).
• No full US approval was in hand at the time of the extension; other regional regulatory activities (including ongoing Phase III programs) will determine label breadth (nrSPMS +- PPMS).

5. Strong Disability-Slowing Momentum (trial-driven)

• HERCULES demonstrated a meaningful slowing of disability accumulation (reported ~31% reduction in confirmed disability progression in nrSPMS in key analyses), creating momentum around the drug's potential to change the treatment paradigm for progressive MS.
• Early real-world enthusiasm from MS specialists and advocacy groups is translating into optimistic market forecasts, though real uptake will depend on final labeling, safety monitoring requirements, and payer coverage decisions.

6. Competitive Differentiation and Market Trends

• Mechanism & differentiation: As an oral, brain-penetrant BTK inhibitor that targets both peripheral B-cell and CNS microglial signaling, tolebrutinib is differentiated from existing immunomodulators that primarily target peripheral immune activity - giving it a unique value proposition for progressive MS.
• Clinical positioning: Demonstrated effect on disability progression (if confirmed by regulators) positions tolebrutinib as potentially first-in-class for slowing progression independent of relapse activity - a major competitive edge in progressive MS.
• Market trends supporting uptake: Increasing focus on therapies that address neurodegeneration and progression (not just relapses), use of imaging/biomarker stratification (e.g., paramagnetic rim lesions) to identify candidates, and willingness of payers to reimburse impactful DMTs all support its case - assuming safety and cost-effectiveness are acceptable.
• Risks & headwinds: Regulatory delays (recent FDA extension), mixed results in relapsing MS trials, prior safety signals (liver enzyme elevations and infection risk seen in some BTK programs), payer scrutiny on cost-effectiveness, and competition from other BTK inhibitors and neuroprotective strategies are material risks that could affect market penetration.

Tolebrutinib Recent Developments

• In September 2025, the US FDA has extended by three months the target action date of its review of the new drug application (NDA) of Tolebrutinib, an oral and brain-penetrant investigational Bruton's tyrosine kinase (BTK) inhibitor to treat non-relapsing, secondary progressive multiple sclerosis (nrSPMS) and to slow disability accumulation independent of relapse activity in adult patients.
• In October 2024, treatment with Tolebrutinib resulted in delay in time-to-onset of disability progression in non-relapsing secondary progressive multiple sclerosis (nrSPMS) and Phase III trial presented at the 40th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).
