At the AD/PD 2025 conference, TauRx Pharmaceuticals reported positive results for Hydromethylthionine Mesylate (HMTM), an oral tau aggregation inhibitor. The therapy demonstrated an ability to slow cognitive decline and reduce brain atrophy over 18 months in early to moderate Alzheimer’s patients, with a favorable safety profile. Regulatory filings are underway in the UK, with plans to seek approvals in the U.S. and Canada by 2026, underscoring its potential impact on market expansion.

Market Trends

Emergence of Novel Therapeutic Approaches

The Alzheimer’s therapeutics market is witnessing a strong shift from symptomatic treatments, such as donepezil and memantine, toward innovative disease-modifying therapies (DMTs). These novel approaches target underlying disease mechanisms, offering improved outcomes for patients with early-stage Alzheimer’s.

• For instance, in January 2025, the U.S. FDA approved Eisai’s Supplemental Biologics License Application (sBLA) for lecanemab irmb (LEQEMBI), a monoclonal antibody designed to slow cognitive decline in mild cognitive impairment and early Alzheimer’s disease.

Thus, the growing approval of such DMTs underscores a paradigm shift in treatment, fueling demand for advanced therapies that move beyond symptom management to address disease progression.

Use of Rapid Blood Tests for Alzheimer’s Detection

The growing emphasis on early and accurate Alzheimer’s detection is driving the adoption of innovative diagnostic methods, with blood-based testing emerging as a transformative trend.

• In May 2025, the FDA approved the first Alzheimer’s blood test (Lumipulse G pTau217/β Amyloid 1-42), offering a faster, less invasive, and cost-effective alternative to PET scans and spinal taps, enabling earlier diagnosis and treatment decisions.

Such innovations are expected to expand diagnosis rates and fuel demand for Alzheimer’s therapeutics globally.

Market Growth Factors

Expanding Reimbursement Coverage Boosts Therapy Adoption

The expansion of reimbursement coverage is a critical driver in the Alzheimer’s therapeutics market, making advanced treatments more accessible. Recent policy updates have ensured that newly approved drugs are covered under Medicare, significantly reducing out-of-pocket costs for patients.

• For example, the U.S. FDA approved Leqembi (July 6, 2023) and Kisunla (July 2, 2024), both now covered under Medicare (NCD 200.3), making them accessible to Alzheimer’s patients.  

Such reimbursement improvements boost therapy adoption and strengthen overall market growth.

New Drug Pipeline beyond Amyloid and New Targets

A major driver of the global market is the emergence of a diversified drug pipeline beyond amyloid beta therapies. While past efforts primarily targeted amyloid plaques with limited success, recent R&D has shifted toward novel mechanisms such as tau protein aggregation, synaptic dysfunction, and neuroinflammation. This broader focus enhances the chances of achieving disease-modifying outcomes and meeting unmet clinical needs. The table below depicts the new drug pipeline for Alzheimer’s, featuring leading candidates under development:

Such advancements strengthen therapeutic innovation, fueling market growth and future treatment breakthroughs.

Market Restraint

Safety Concerns Limit Adoption of Alzheimer’s Therapies

The Alzheimer’s therapeutics market faces a significant restraint due to the serious side effects associated with approved treatments. Many monoclonal antibodies based therapies, though promising in slowing disease progression, pose considerable risks that limit patient adoption and physician confidence.

• For instance, LEQEMBI and Kisunla face concerns over severe side effects, including ARIA linked to brain swelling, bleeding, seizures, and fatal outcomes, along with allergic and infusion reactions, requiring MRI monitoring and restricting broader adoption among Alzheimer’s patients.

Such risks not only impact patient safety but also raise regulatory hurdles, reduce prescription rates, and increase overall treatment costs, hampering market growth.

Market Opportunity

Expanding Research Funding

The global market offers significant funding opportunities to advance research in Alzheimer’s and related dementias. The growing prevalence of neurodegenerative disorders has prompted governments, non-profits, and private organizations to invest in innovative treatments, early diagnostics, and disease-modifying therapies.

• In March 2025, the U.S. Department of Defense’s CDMRP launched the Alzheimer’s Research Program, allocating USD 650M for solution-oriented research to improve the lives of patients, families, and veterans.

Such funding supports clinical trials, biomarker discovery, and collaborations, accelerating therapeutic development globally.
