Progressive supranuclear palsy (PSP) is a rare, progressive neurodegenerative tauopathy that impairs balance, movement, eye control, and cognition. According to Reema A Sharaf et al., 2024, it affects about 5 to 6 individuals per 100,000 people globally. According to the progressive supranuclear palsy pipeline analysis by Expert Market Research, the drug landscape is expanding with multiple candidates targeting tau pathology and neurodegeneration, spanning Phase II and III development, reflecting a growing focus on disease‑modifying therapies. The growing prevalence, heightened diagnostic recognition, and unmet medical needs are expected to drive pipeline innovation and market growth in the coming years.
Major companies involved in the progressive supranuclear palsy pipeline analysis include Amylyx Pharmaceuticals Inc., Ferrer Internacional S.A., and others.
Leading drugs currently in the pipeline include AMX0035, FNP-223, UCB0107 (Bepranemab), and others.
The pipeline shows significant expansion driven by emerging disease-modifying therapies, increasing clinical trials targeting tau protein, and growing investment in neurodegenerative research, indicating robust development momentum in the coming years.
The Progressive Supranuclear Palsy Pipeline Analysis Report by Expert Market Research gives comprehensive insights into progressive supranuclear palsy therapeutics currently undergoing clinical trials. It covers various aspects related to the details of each of these drugs under development for progressive supranuclear palsy. The progressive supranuclear palsy report assessment includes the analysis of over 100 pipeline drugs and 50+ companies. The progressive supranuclear palsy pipeline landscape will include an analysis based on efficacy and safety measure outcomes published for the trials, including their adverse effects on patients suffering from the condition, and alignment with progressive supranuclear palsy treatment guidelines to ensure optimal care practices.
The assessment part will include a detailed analysis of each drug, drug class, clinical studies, phase type, drug type, route of administration, and ongoing product development activities related to progressive supranuclear palsy.

Progressive supranuclear palsy (PSP) is a rare neurodegenerative disorder characterized by impaired balance, gait difficulties, eye movement abnormalities, speech problems, and cognitive decline. It occurs due to abnormal accumulation of tau proteins in specific brain regions, leading to progressive neuronal damage and dysfunction, primarily affecting individuals over 60 years of age.
Progressive supranuclear palsy treatments focus on symptom management and disease modification, including physical therapy, medications for motor and cognitive symptoms, and investigational therapies targeting tau protein accumulation. In June 2025, FNP-223, an orally administered O-GlcNAcase inhibitor, received FDA Fast Track designation for Progressive Supranuclear Palsy. Currently in Phase 2 trials, FNP-223 aims to reduce abnormal tau aggregation, offering a potential disease-modifying therapy for PSP-Richardson syndrome patients.
The pipeline is gaining attention due to the disease’s epidemiology and unmet medical needs. According to Reema A. Sharaf et al., 2024, the disease affects approximately 5 to 6 people per 100,000 population. As per Shashank Agarwal et al., 2023, incidence increases with age, from 1.7 cases per 100,000 at ages 50–59 years to 14.7 per 100,000 at 80–89 years. The mean age of onset is around 65 years, and cases under 40 are extremely rare. Improved recognition of clinical variants is driving research and the development of targeted therapies.

By Route of Administration
The pipeline assessment report covers 50+ drug analyses based on the route of administration:
The report covers phase I, phase II, phase III, phase IV, and early-phase drugs. The coverage includes an in-depth analysis of each drug across these phases. According to EMR analysis, phase II covers a major share of the total progressive supranuclear palsy clinical trials, with 58%, reflecting significant clinical development and potential near-term therapies. Early phase I represents 17% of the pipeline, while phase I, phase III, and phase IV each represent 8% reflecting later-stage clinical development, supporting innovation and potential expansion of effective progressive supranuclear palsy treatments.
The drug molecule categories covered under the progressive supranuclear palsy pipeline analysis include small molecules, monoclonal antibodies, and peptides. The progressive supranuclear palsy report provides a comparative analysis of the drug classes for each drug in various phases of clinical trials for progressive supranuclear palsy. Peptide-based therapies are gaining attention in the progressive supranuclear palsy market for their potential to modify disease progression. For instance, GV1001, a peptide drug developed by GemVax & KAEL Co., Ltd., is under investigation. Phase 2a trial results demonstrated improvements in PSP-Rating Scale scores and responder rates, supporting further evaluation in Phase 3 studies as a promising therapeutic option.
The EMR report for the progressive supranuclear palsy pipeline covers the profile of key companies involved in clinical trials and their drugs under development. It provides a detailed progressive supranuclear palsy therapeutic assessment, analyzing the competitive dynamics of the clinical trial landscape. Below is the list of a few players involved in progressive supranuclear palsy clinical trials:
This section covers the detailed analysis of each drug under multiple phases, including phase I, phase II, phase III, phase IV, and emerging drugs for progressive supranuclear palsy. It includes product description, trial ID, study type, drug class, mode of administration, and recruitment status of progressive supranuclear palsy drug candidates.
FNP-223, sponsored by Ferrer Internacional S.A., is an orally administered O-GlcNAcase (OGA) inhibitor currently being evaluated in a Phase 2 PROSPER trial for progressive supranuclear palsy (PSP). The study examines the efficacy of FNP-223 in slowing disease progression over 52 weeks using the PSP Rating Scale (PSPRS), while also assessing its safety, tolerability, and pharmacokinetics. Mechanistically, FNP-223 binds to the active site of the OGA enzyme, preventing the removal of O-GlcNAc modifications from tau proteins. This increases glycosylated tau, reducing abnormal tau aggregates and neurofibrillary tangles, potentially slowing neurodegeneration in PSP.
UCB0107 (Bepranemab) is a monoclonal antibody drug being developed to target progressive supranuclear palsy (PSP). Sponsored by UCB Biopharma SRL, this Phase 1 study is actively examining the long-term safety and tolerability of intravenous administration of Bepranemab in study participants. The drug is delivered as a solution for infusion, allowing direct entry into the bloodstream to reach the brain efficiently. Bepranemab is designed to modulate pathological tau protein aggregation, a key factor in PSP progression. This open-label extension study is continuously monitoring participants to evaluate the drug’s safety profile and potential therapeutic effects over an extended period.
