Overview
New York, NY – Feb 18, 2026 – The Global Hunter Syndrome Treatment Market size is expected to be worth around US$ 2.6 Billion by 2033, from US$ 1.5 Billion in 2023, growing at a CAGR of 5.5% during the forecast period from 2024 to 2033. North America maintained a leading position in the market, accounting for over 38% of the share, with a market value of approximately US$ 0.5 billion.
A structured strategic framework has been introduced to advance innovation in Hunter syndrome treatment, addressing a critical unmet need within the rare disease therapeutic landscape. Hunter syndrome, also known as Mucopolysaccharidosis Type II (MPS II), is a rare, inherited lysosomal storage disorder characterized by deficient iduronate-2-sulfatase enzyme activity, leading to progressive multi-organ complications.
The newly outlined development initiative is focused on enhancing enzyme replacement therapies (ERT), advancing gene therapy platforms, and strengthening supportive care approaches to improve long-term clinical outcomes. Emphasis is being placed on next-generation treatment modalities designed to address neurological manifestations, which remain inadequately managed through conventional therapies.
Strategic collaborations with biotechnology innovators, research institutions, and regulatory authorities are being reinforced to accelerate clinical development and streamline approval pathways. Advanced technologies, including gene-editing tools and precision delivery systems, are being evaluated to improve therapeutic efficacy and reduce disease burden.
The global Hunter syndrome treatment market is anticipated to witness steady growth, supported by increasing disease awareness, expanded newborn screening programs, and rising investment in orphan drug development. Regulatory incentives for rare disease therapies continue to encourage pipeline expansion and commercialization efforts.
This foundational advancement reflects a long-term commitment to improving patient quality of life, expanding access to innovative therapies, and strengthening the rare disease treatment ecosystem through sustained research and strategic investment initiatives.

Emerging Trends
- One-Time Gene Therapy Modalities: Single-administration gene therapies based on adeno-associated virus vectors are being evaluated to deliver a functional IDS gene. Clinical programs such as RGX-121 are assessing whether durable enzyme restoration can reduce reliance on lifelong weekly infusions and lower treatment burden.
- Intrathecal Enzyme Replacement for Neurological Involvement: Intrathecal enzyme replacement therapy has been explored to overcome the blood–brain barrier and target central nervous system manifestations. Idursulfase-IT received orphan drug designation from the U.S. FDA in 2009, reflecting a strategic shift toward addressing neurocognitive complications.
- Substrate Reduction Therapy Development: Substrate reduction therapy focuses on small molecules designed to inhibit glycosaminoglycan synthesis. Early-stage research indicates that this approach may reduce intracellular substrate accumulation and potentially complement enzyme replacement therapy, with the added advantage of future oral administration.
- Hematopoietic Stem Cell and Gene-Modified Therapies: Therapeutic strategies combining hematopoietic stem cell transplantation with gene-editing technologies are under investigation. These approaches aim to introduce corrected genetic material into patients’ own cells, enabling sustained systemic enzyme production and improved tissue-level distribution.
- Fusion Protein and Transport-Enhanced Platforms: Innovative fusion protein therapies, including Tividenofusp Alfa (DNL310), are being tested to enhance intracellular enzyme delivery. These engineered constructs incorporate transport domains to improve tissue penetration, potentially enhancing therapeutic effectiveness while reducing infusion frequency.
Use Cases
- Weekly Idursulfase Administration in Pediatric Patients: In a 53-week clinical safety evaluation, young pediatric patients received weekly intravenous idursulfase at 0.5 mg/kg. The therapy demonstrated an acceptable safety profile, with limited infusion-related reactions such as mild rash and occasional nausea.
- Functional and Cardiopulmonary Improvements in Adults: Adult patients undergoing regular idursulfase therapy demonstrated measurable functional benefits, including increased six-minute walk test distance and improved forced vital capacity. Cardiac outcomes were also favorable, with reductions observed in left ventricular mass index following sustained treatment.
- Clinical Outcomes of Idursulfase Beta: A 52-week controlled study involving male participants indicated that idursulfase beta achieved superior outcomes compared to placebo. Significant improvements were recorded in walking distance, urinary glycosaminoglycan reduction, and reductions in liver and spleen volumes, supporting its therapeutic efficacy.
