Investment Context Progressive Supranuclear Palsy represents a significant unmet medical need in the neurodegenerative disease landscape. With approximately 49 clinical trials and 12 actively recruiting, the PSP research ecosystem has grown substantially over the past five years[@smith2023]. The pure 4R-tau pathology makes PSP an attractive indication for anti-tau therapeutic development, with several high-profile Phase 2 readouts in 2024[@mendonca2024; @holmes2024].
Key Investment Themes
Tau Targeting : Primary therapeutic focus given tau pathology
Neuroprotection : Preserving vertical gaze and motor function
Biomarker Development : NfL, tau PET for patient stratification[@anthony2024; @leahy2025]
RNA-targeting Modalities : ASO and RNAi therapeutics[@choi2025]
Emerging Investment Areas
Anti-tau Immunotherapy : Gosuranemab (Biogen), Tilavonemab (AbbVie), Bepranemab (UCB)
Tau PET Imaging : PI-2620, other 4R-tau selective ligands
RNA Therapeutics : BIIB080 (MAPTRx) ASO showing promise
Biomarker-Driven Trials : NfL as endpoint, tau PET for enrollment
Priority Research Gaps
Biomarker Validation While NfL shows promise as a progression biomarker, additional validation is needed for clinical trial endpoints[@anthony2024]. Tau PET ligands specific for 4R-tau are in development but not yet validated for PSP[@leahy2025].
Disease Modification Endpoints The field needs better understanding of clinically meaningful endpoints beyond traditional scale-based measures.
Recommended Priorities
Biomarker standardization : Harmonize NfL and tau PET methodologies
Trial design innovation : Adaptive trials and platform protocols
Patient recruitment : Investment in trial-ready cohorts and registry infrastructure
Therapeutic Target Priorities Based on trial count analysis, the following mechanism categories represent either well-invested areas or underserved opportunities:
| Priority | Mechanism | Trials | Investment Level | |----------|-----------|--------|-----------------| | High | Tau immunotherapy | 5 | Well-funded | | High | RNA targeting | 1 | Emerging | | Medium | Neuroprotection | 8 | Moderate | | Medium | Symptomatic (motor) | 12 | Well-funded | | Low | Non-motor symptoms | 6 | Underserved |
Investment Outlook
Near-Term Opportunities (1-3 Years)
2024-2025 Phase 2 readouts : Gosuranemab, Tilavonemab, Bepranemab results
Biomarker-positive trials : Enrichment using tau PET and NfL
Regulatory clarity : FDA/EMA guidance on disease-modifying endpoints
Medium-Term Opportunities (3-5 Years)
ASO expansion : BIIB080 Phase 2/3 development
Combination therapy trials : Immunotherapy + small molecule
Personalized medicine : Genetic stratification (MAPT, GRN, CBD)
Long-Term Vision (5-10 Years)
Prevention trials : Pre-symptomatic populations with genetic risk
Gene therapy : AAV-delivered anti-tau constructs
Disease-modifying therapies : Potential disease reversal
