Investor sentiment whipsaws with each negative headline, trimming venture outlays by 23% in 2024. Sponsors now embed adaptive design features, biomarker-defined cohorts, and Bayesian statistics to salvage underperforming assets more quickly. Regulators encourage interim futility analyses to conserve resources, but the underlying biological complexity keeps success odds modest. Despite process improvements, persistent attrition remains a material drag on the neurodegenerative disease market expansion.

Segment Analysis

By Indication: Alzheimer’s Disease Dominates Despite ALS Growth

Alzheimer’s disease commanded 42.34% neurodegenerative disease market share in 2024, buoyed by high prevalence and multiple labeled therapies. The 2025 surge in Leqembi revenue, topping JPY 23.1 billion (USD 154 million), reaffirmed commercial headroom for disease-modifying antibodies. Parkinson’s and multiple sclerosis sustain volume through entrenched dopaminergic and immunomodulatory regimens, yet incremental innovation remains slower. ALS, albeit small, posts a 9.65% CAGR, supported by gene-silencing candidates and expanded newborn-screening programs.
