Huntington's Disease Understanding and Treatment Algorithm

Huntington's Disease Overview and Diagnosis

Huntington's disease is a rare, inherited, progressive brain disorder caused by a mutation in the HTT gene on chromosome 4, leading to the production of abnormal huntingtin protein and gradual nerve cell damage. It follows an autosomal dominant pattern, meaning individuals who inherit the faulty gene will develop the disease. Symptoms typically appear in adulthood and include involuntary movements (chorea), cognitive decline, and psychiatric issues such as depression and irritability. Diagnosis is based on clinical evaluation, family history, genetic (blood) testing, and imaging techniques such as CT or MRI scans. While there is no cure, treatment focuses on managing symptoms and providing supportive care as the disease progresses.

Current Huntington's Disease Treatment Landscape

There is currently no cure or disease-modifying therapy for Huntington's disease; treatment focuses on managing symptoms and improving quality of life. Medications are used to control movement disorders and psychiatric symptoms. Deutetrabenazine and Tetrabenazine are approved for treating chorea, while antidepressants, antipsychotics, and mood stabilizers help manage depression, irritability, and behavioral changes. Supportive care, including physical therapy, occupational therapy, and speech therapy, plays a key role in maintaining function and independence. As the disease progresses, patients often require increasing assistance, supervision, and comprehensive caregiving support.

Huntington's Disease Unmet Needs

Approved Therapies for Huntington's Disease

Deutetrabenazine (AUSTEDO): Teva Pharmaceuticals

AUSTEDO is a deuterated form of a small molecule inhibitor of vesicular monoamine 2 transporter, or VMAT2, that is designed to regulate the levels of a specific neurotransmitter, dopamine, in the brain. It is indicated in adults for the treatment of Chorea associated with Huntington's disease. The FDA granted AUSTEDO New Chemical Entity Exclusivity until April 2022 and Orphan Drug exclusivity for the treatment of chorea associated with Huntington disease until April 2024.

In May 2024, Teva Pharmaceuticals announced that the US Food and Drug Administration (FDA) had approved AUSTEDO XR as a one-pill, once-daily treatment option, now with four new tablet strengths (30, 36, 42, 48 mg) indicated in adults for tardive dyskinesia and Huntington disease chorea.

INGREZZA (valbenazine/NBI-98854): Neurocrine Biosciences

INGREZZA is a selective VMAT2 inhibitor, believed to work by reducing the amount of dopamine released in a region of the brain that controls movement and motor function. In August 2023, the FDA granted approval for INGREZZA capsules to treat chorea in adults with Huntington's disease. The FDA approval is supported by data from two clinical studies conducted in collaboration with the Huntington Study Group (HSG), including the KINECT-HD Phase III study and the ongoing KINECT-HD2 open-label extension trial.

Huntington's Disease Pipeline Analysis

SKY-0515: Skyhawk Therapeutics

SKY-0515 is an orally-administered, investigational small molecule RNA modulator developed through the company's novel RNA-modulating platform, SKYSTAR. SKY-0515 therapeutically reduces both HTT protein and PMS1 protein. PMS1 is an additional key driver of somatic CAG repeat expansion and HD pathology and should complement the benefits of reducing mutant HTT. Skyhawk also announced that its SKY-0515 Phase II/III FALCON-HD trial, open at twelve sites in Australia and New Zealand, has expanded worldwide. Skyhawk has now treated more than 90 patients with SKY-0515.

• In January 2026, Skyhawk Therapeutics reported positive results from a nine-month interim analysis of its Phase I trial evaluating SKY-0515 for Huntington's Disease.

Votoplam (PTC518): Novartis Pharmaceuticals

PTC518 is a small molecule splicing modifier that acts via a unique mechanism to promote the inclusion of a novel pseudoexon containing a premature termination codon, thus triggering Huntingtin (HTT) mRNA degradation and subsequent reduction in HTT protein levels.

• In March 2025, PTC Therapeutics announced results from the Phase II PIVOT-HD study of PTC518 (votoplam) in Stage 2 and Stage 3 Huntington's disease patients. The study met its primary endpoint of reduction in blood Huntingtin (HTT) protein levels (p<0.0001) at Week 12 and favorable safety and tolerability. In addition, the 12-month data from the Stage 2 patients are consistent with the previously reported dose-dependent lowering of HTT protein and dose-dependent trends across clinical scales.
• In December 2024, Novartis announced that it had entered into a global license and collaboration agreement with PTC Therapeutics for PTC518, an HTT mRNA splice modulator with the potential to become the first oral disease-modifying therapy for Huntington's disease.

• In March 2025, PTC Therapeutics announced results from the Phase II PIVOT-HD study of PTC518 (votoplam) in Stage 2 and Stage 3 Huntington's disease patients. The study met its primary endpoint of reduction in blood Huntingtin (HTT) protein levels (p<0.0001) at Week 12 and favorable safety and tolerability. In addition, the 12-month data from the Stage 2 patients are consistent with the previously reported dose-dependent lowering of HTT protein and dose-dependent trends across clinical scales.

Huntington's Disease Market Outlook

The treatment landscape for Huntington's disease remains highly limited and largely symptomatic, with no approved disease-modifying therapies currently available. Existing pharmacological options primarily focus on managing motor symptoms such as chorea and addressing psychiatric manifestations, with agents like Deutetrabenazine and Tetrabenazine forming the cornerstone of therapy. As a result, the market size remains relatively small compared to other neurodegenerative disorders, driven by the disease's rare prevalence and limited therapeutic options.

However, the Huntington's disease pipeline is evolving, with increasing focus on disease-modifying approaches such as Gene silencing therapies, Antisense oligonucleotides, RNA-targeting strategies, and cell-based therapies aimed at reducing mutant huntingtin protein expression. These emerging modalities have the potential to transform the treatment paradigm if proven effective, shifting the market from symptomatic management to targeted, mechanism-based interventions.

Despite this progress, several challenges continue to restrain market growth, including high clinical trial failure rates, complexities in targeting the central nervous system, limited patient populations for large-scale studies, and regulatory uncertainties. Additionally, the lack of validated biomarkers and standardized endpoints complicates drug development and approval pathways.

Looking ahead, the market is expected to witness gradual growth driven by advancements in precision medicine, increasing research investments, and improved understanding of disease biology. The successful launch of disease-modifying therapies, along with enhanced diagnostic capabilities and patient identification, is anticipated to significantly expand the market potential and improve long-term outcomes for patients with Huntington's disease.

• In 2025, the total market size of Huntington's disease by therapies was USD 320 million in the 7MM. The highest revenue was captured by AUSTEDO, accounting for USD 167 million in 2025.
• During the forecast period (2026-2036), pipeline candidates such as SKY-0515, PTC518, and others are expected to drive the growth of the Huntington's disease market size.

Drug Class/Insights into Leading Emerging and Marketed Therapies in Huntington's Disease (2022-2036 Forecast)

The treatment landscape of Huntington's disease remains limited and is primarily focused on symptomatic management; however, emerging therapeutic approaches are targeting the underlying genetic cause and disease progression.

Gene-targeting therapies: Advanced approaches such as antisense oligonucleotides (ASOs) and RNA interference (RNAi) therapies aim to reduce the production of mutant huntingtin protein, which is the root cause of neuronal damage in Huntington's disease. These therapies work by selectively silencing or modifying the expression of the faulty gene and are currently being evaluated in clinical trials as potential disease-modifying options.

Small molecules: Existing pharmacological treatments mainly address symptoms rather than disease progression. Agents such as Deutetrabenazine and Tetrabenazine are used to manage chorea, while other small molecules, including antidepressants, antipsychotics, and mood stabilizers, are used to control psychiatric and behavioral symptoms.
