According to DelveInsight’s analysis, the Huntington’s Disease pipeline features more than 20 leading companies actively engaged in developing over 20 therapeutic candidates aimed at treating Huntington’s Disease.
Huntington’s Disease Overview:
Huntington’s disease is an inherited, progressive neurodegenerative disorder characterized by the gradual development of involuntary movements in the hands, feet, face, and trunk, along with a continuous decline in cognitive and memory functions that eventually leads to dementia. The condition stems from damage to specific brain regions responsible for movement, mood regulation, and cognition. Symptoms usually appear between the ages of 30 and 50 but can manifest as early as 2 or as late as 80. A key feature of the disease is chorea—sudden, uncontrollable muscle movements such as jerks or twitches. As the disease progresses, patients may experience worsening coordination, personality and mood changes, speech difficulties, memory impairment, and intensified involuntary movements.
Huntington’s disease follows an autosomal dominant inheritance pattern, meaning that a single copy of the defective gene can cause the condition. It is associated with a mutation in the huntingtin gene located on chromosome 4. Although the precise role of the normal huntingtin protein is not fully understood, the mutated version is toxic to brain cells. This mutation involves an abnormal expansion of a DNA sequence (CAG repeat). While healthy individuals have 17–20 repeats, those with Huntington’s disease typically possess 40 or more, leading to the formation of a harmful huntingtin protein that disrupts neuronal function and contributes to movement abnormalities, cognitive decline, and emotional disturbances such as depression and irritability.

"Huntington’s Disease Pipeline Insight 2025" report by DelveInsight provides a comprehensive analysis of the ongoing clinical development activities and growth prospects across the Huntington’s Disease Therapeutics Market.
Key Takeaways from the Huntington’s Disease Pipeline Report
-
DelveInsight’s Huntington’s Disease pipeline report highlights a dynamic landscape, with over 20 active companies developing more than 20 investigational therapies for the treatment of Huntington’s Disease.
-
In April 2025, the FDA granted Breakthrough Therapy designation based on interim Phase I/II results demonstrating a substantial reduction in disease progression—approximately 80% at higher doses—on the composite Unified Huntington’s Disease Rating Scale (cUHDRS). These findings were further supported by favorable biomarker data, including decreased neurofilament light chain levels in treated patients compared to external natural-history controls.
-
Leading companies such as Hoffmann-La Roche, PTC Therapeutics, Annexon, Alnylam Pharmaceuticals, Neuvivo, and BPG Bio are actively advancing novel therapeutic approaches aimed at transforming the Huntington’s Disease treatment landscape. Notable pipeline candidates currently in various stages of development include RG6042, PTC518, ALN-HTT02, and others.

Huntington’s Disease Emerging Drugs
-
RG6042: Hoffmann-La Roche
Tominersen (also known as ASO-HTT or RG6042) is an antisense oligonucleotide therapy in development for the treatment of Huntington’s disease. It is designed to reduce the production of the huntingtin (HTT) protein—both the normal and the mutant forms (mHTT), the latter being responsible for disease onset and progression. The therapy is currently in Phase III clinical trials to assess its efficacy and safety in patients with Huntington’s disease.
-
PTC518: PTC Therapeutics
PTC518 is an orally available small molecule developed to reduce the production of the mutant huntingtin protein, which drives neuronal degeneration and disease progression in Huntington’s disease. The drug is capable of crossing the blood-brain barrier, exhibits selective activity, offers dose flexibility (titratable), and is not subject to efflux from the brain. PTC518 is currently being evaluated in Phase II clinical trials for the treatment of Huntington’s disease.
Huntington’s Disease Companies
Around 20 or more major companies are actively engaged in developing therapies for Huntington’s disease. Among them, Hoffmann-La Roche has a drug candidate currently in the most advanced phase of development—Phase III.
