Neuroprotective and Remyelinating Agents: Shaping the PPMS Market

The Primary Progressive Multiple Sclerosis (PPMS) market is experiencing a dynamic shift, marked by ongoing advancements in therapeutic development, increasing disease awareness, and a focused effort to meet long-standing clinical gaps. As a rare subtype of multiple sclerosis (MS), PPMS accounts for approximately 15% of the global MS population and is characterized by continuous neurological decline without clear periods of remission. Unlike the more common relapsing-remitting form, PPMS presents a unique set of challenges due to its progressive nature and limited treatment options. However, recent breakthroughs in neuroprotective and remyelinating agents are reshaping the therapeutic landscape, offering renewed hope for patients and transforming the overall outlook of the neurodegenerative disease market.

Primary Progressive Multiple Sclerosis Market Overview

The Primary Progressive Multiple Sclerosis treatment market is forecast to grow steadily over the next decade, driven by an increase in disease prevalence, enhanced diagnostic practices, and the approval of targeted disease-modifying therapies (DMTs). Historically, MS treatments were developed with a focus on relapsing forms, leaving PPMS largely unaddressed. This changed with the approval of Ocrelizumab for Primary Progressive Multiple Sclerosis, which became the first and only FDA-approved treatment specifically indicated for PPMS. This milestone has set the stage for intensified research and development activities, with pharmaceutical companies now prioritizing agents that offer neuroprotection and promote myelin repair—two core strategies believed to be essential for managing disease progression in PPMS patients.

Primary Progressive Multiple Sclerosis Epidemiology

Recent Primary Progressive Multiple Sclerosis epidemiology trends reveal a worrying increase in global MS prevalence, with over 3 million individuals affected worldwide. Of this population, approximately 450,000 are estimated to have PPMS. Higher prevalence rates are recorded in North America and Europe, while underdiagnosis remains prevalent in Asia-Pacific and other developing regions due to disparities in healthcare access and imaging technologies. Furthermore, the aging population in developed nations, particularly among individuals aged 40 to 60 years—the primary demographic affected by PPMS—is expected to contribute to a growing patient base. Improved diagnostic capabilities, including magnetic resonance imaging (MRI) and cerebrospinal fluid biomarker testing, are facilitating earlier and more accurate identification of PPMS cases, though challenges remain in resource-limited settings.

Primary Progressive Multiple Sclerosis Market Drivers

The current Primary Progressive Multiple Sclerosis market drivers include rising disease awareness, the success of B-cell-depleting therapies, and increasing investments in precision medicine. Ocrelizumab’s approval has validated the role of B-cell modulation in managing PPMS, spurring interest in similar and complementary approaches. In parallel, the integration of digital health solutions—such as wearable devices that track mobility and cognitive function—has enabled the collection of real-world evidence, supporting more robust clinical trial designs. Additionally, incentives from global regulatory bodies for the development of orphan drugs have further encouraged innovation in this challenging therapeutic space. These combined factors are accelerating the pace at which new treatments are entering the Primary Progressive Multiple Sclerosis pipeline.

Primary Progressive Multiple Sclerosis Unmet Needs

Nonetheless, Primary Progressive Multiple Sclerosis unmet needs persist. Nearly 40% of patients with non-active PPMS remain untreated, largely due to the lack of therapies targeting advanced or non-inflammatory stages of the disease. Even among those receiving treatment, many continue to experience steady neurological decline. This underscores the pressing need for more potent agents with neuroprotective and remyelinating capabilities. Furthermore, the high cost of existing therapies creates accessibility issues, particularly in healthcare systems lacking comprehensive reimbursement models. Cognitive decline, fatigue, and non-motor symptoms remain inadequately addressed by current DMTs. Compounding these issues is the absence of validated biomarkers to monitor treatment efficacy, which significantly hampers the personalization of care and complicates long-term disease management.

Primary Progressive Multiple Sclerosis Competitive Landscape

From a Primary Progressive Multiple Sclerosis competitive landscape standpoint, the therapeutic pipeline is increasingly diversified, reflecting a deeper understanding of PPMS pathophysiology. Agents targeting Bruton tyrosine kinase (BTK), such as tolebrutinib and evobrutinib, are showing promise for their dual mechanisms of action—modulating both peripheral B cells and central nervous system microglia. Similarly, investigational therapies like CNM-Au8, a nanocatalytic antioxidant, aim to protect neurons and support remyelination. The continued development of subcutaneous formulations of existing drugs, such as Roche’s version of ocrelizumab, is enhancing treatment adherence by offering more convenient administration routes. Meanwhile, emerging players like MediciNova and ImStem Biotechnology are exploring immunomodulatory vaccines and stem cell-based approaches, indicating a move beyond traditional DMTs toward regenerative and reparative strategies.
