¶ Huntington's Disease Investment Landscape
The Huntington's Disease investment landscape centers on lowering mutant huntingtin protein through gene silencing, gene editing, and small molecule approaches class="ref-link" data-ref-number="10" data-ref-text="Koyyalagunta L et al. Novel small molecule modifiers of mutant huntingtin protein aggregation (2024)." title="Koyyalagunta L et al. Novel small molecule modifiers of mutant huntingtin protein aggregation (2024).">10. The field was transformed by the Tominersen trial and
continues to advance with new technologies1, representing significant
therapeutic strategies7.
Huntington's Disease affects approximately 30,000 patients in the United States with another 200,000 at risk, representing a significant unmet medical need class="ref-link" data-ref-number="2" data-ref-text="Ross CA et al. Huntington's Disease: natural history, biomarkers and prospects for therapeutics (2014)." title="Ross CA et al.

Huntington's Disease is caused by CAG repeat expansion in the HTT gene, leading to progressive motor, cognitive, and psychiatric decline9. The autosomal dominant nature of the disease makes it an attractive target for gene-silencing approaches that can reduce production of the toxic mutant protein3.
- VMAT2 inhibitor Mechanism:
- Indication: Chorea management

- Indication: Chorea in Huntington's Disease
Gene silencing represents the most advanced approach to disease modification6:
- Tominersen (Roche/IONIS): Antisense oligonucleotide targeting HTT, previously in phase 3 (development was paused but program continues in different formats)4
- AMT-130 (UniQure): AAV gene therapy for HTT lowering, showing promise in early clinical trials5
- VTT-801 (VIRxSYS): AAV-based approach in development
Emerging gene editing approaches offer potential for permanent correction:
- CRISPR approaches: Various programs in preclinical development
- Base editing: Precision editing of CAG repeat
- Prime editing: Emerging technology with potential for repeat contraction
Supporting neuronal health while targeting the underlying cause:
- Pridopidine: Dopamine stabilizer in clinical trials
- Semaglutide: GLP-1 receptor agonist with neuroprotective properties
- CNM-Au8: Bioenergetic support for mitochondrial function
¶ Major Companies and Pipeline Programs
- Tominersen: ASO for HTT lowering, lessons from phase 3 informing next-generation programs
- AMT-130: AAV gene therapy, first gene therapy for HD in clinical trials
- Valbenazine: VMAT2 inhibitor for chorea management
- Pridopidine: Phase 3 development for motor function preservation
- WVE-003: ASO targeting mutant HTT allele
¶ Investment Themes and Research Priorities
Central focus of disease modification:
- ASOs (antisense oligonucleotides) for allele-selective lowering
- AAV-delivered shRNA for long-term expression
- Gene editing approaches for permanent correction
Critical for clinical trial success:
- Mutant huntingtin measurement in CSF and blood
- Neurofilament light chain tracking
- MRI and PET imaging biomarkers
Addressing quality of life:
- Motor symptoms (chorea management)
- Cognitive decline prevention
- Psychiatric manifestation treatment
