무코다당증 I형(MPS I)에 대한 이해와 치료 알고리즘

무코다당증 I형(MPS I)의 개요 및 진단

MPS i는 데르마탄 황산염이나 헤파란 황산염 등의 글리코사미노글리칸(GAG) 분해에 필수적인 효소인 α-L-이드론니데이스(IDUA)의 결핍으로 인해 발생하는 희귀 유전성 리소좀 축적증입니다. 이러한 물질이 축적되면 진행성 세포 및 조직 기능 장애를 유발하여, 골격계, 심혈관계, 호흡기계, 신경계를 포함한 여러 장기계에 영향을 미칩니다.

무코다당증 I형의 진단에는 GAG 분석, 효소 활성 측정 및 유전자 검사가 포함되며, 이를 통해 조기 치료, 예후 평가 및 유전 상담이 가능해집니다. 선별 검진 프로그램은 조기 발견을 돕고, 폐기능 검사, 수면 다원 검사, 청력 검사, 안과 검사, 골격 영상 검사, 인지 기능 평가 등 종합적인 평가는 질환의 경과 관찰에 도움이 됩니다. 신생아 선별검사와 분자 검사는 환자 관리를 최적화하고 장기적인 예후를 개선하는 데 있어 매우 중요한 역할을 하고 있습니다.

무코다당증 I형(MPS I) 치료의 현황

무코다당증 I형의 치료는 질환의 중증도에 따라 이루어지며, 특히 유년기의 중증 환자에 대해서는 인지 기능을 유지할 수 있다는 점에서 조혈모세포 이식(HSCT)이 권장됩니다. 한편, 효소 대체 요법(ERT)은 주로 신체적 증상을 완화하는 데 목적이 있습니다. 그러나 두 접근법 모두, 특히 골격계 증상 관리에 있어 한계가 있으므로, 예후를 개선하기 위해서는 조기 개입이 매우 중요합니다. 현재의 표준 치료법인 라로니다제(ALDURAZYME)는 여전히 효능에 한계가 있기 때문에 차세대 치료법 개발이 진행되고 있습니다. OTL-203, 레프나프스프 알파(JR-171), 이드로나클린 겐루코셀-T(ISP-001) 등의 새로운 후보 약물은 보다 종합적인 질환 관리를 실현하는 것을 목표로 하고 있습니다.

기타

전반적으로, 뮤코다당증 I형의 경우, 바이오의약품의 시장 출시, 자가항체 검사(예 : 항-AChR)를 통한 진단 정확도 향상, 그리고 질환에 대한 인지도 제고가 2022년부터 2036년까지 주요 7개국 규모의 뮤코다당증 I형 시장에서 꾸준한 성장을 견인할 것으로 예상되며, 이미 출시된 제품과 개발 중인 파이프라인 모두에 큰 상업적 영향을 미칠 것으로 전망됩니다.

  • 주요 7개국 중 미국은 뮤코다당증 I형의 시장 규모가 가장 크며, 2025년에는 약 7,500만 달러에 달할 것으로 전망됩니다.
  • EU4 국가와 영국을 합친 시장은 효소 보충 요법에 대한 꾸준한 수요에 힘입어 2025년에는 총 시장 규모가 약 7,000만 달러에 달하며 중요한 시장 부문을 차지했습니다.
  • 일본은 2025년에 약 1,000만 달러 규모의 시장을 차지하며, 주요 7개국 시장 전체 중에서는 가장 작지만 지속적으로 성장하고 있는 점유율을 보이고 있습니다.
  • 치료 전망에 있어 최근 가장 중요한 변화는 전신 효소 대체 요법(ERT)의 한계를 해결하는 데 초점이 맞춰져 있다는 점입니다. 라로니다제(ALDURAZYME)는 여전히 EU 시장 전체에서 표준 치료법으로 자리 잡고 있지만, OTL-203(줄기세포 유전자 치료)과 같은 차세대 치료법의 등장은 큰 도약을 의미합니다. 이러한 첨단 메커니즘은 혈액-뇌 장벽(BBB)을 통과하여 보다 종합적인 질환 관리를 실현하는 것을 목표로 하며, 중증 표현형을 보이는 환자의 장기적인 삶의 질을 크게 향상시킵니다.
  • 효소 대체 요법(ERT) : 라로니다제는 IDUA를 순환계로만 전달할 뿐이며, 혈액-뇌 장벽을 통과하는 능력은 제한적이고 반감기도 짧은 것이 특징입니다. HSCT는 인지 기능, 생존율, 성장, 장기 기능을 개선함으로써 질환의 진행을 억제하지만, 골격 이상, 관절 구축, 각막 혼탁에 대한 효과는 제한적입니다.
  • 줄기세포 유전자 치료 : 이는 중증형 뮤코다당증 I형의 표준 치료법이며, 특히 2세 미만의 소아에게 적용되며, 경증형의 경우 선택적 치료법이 됩니다. 이 치료법에서는 기증자 유래 세포가 효소 생성을 촉진하고, 혈액-뇌 장벽(BBB)을 통과하여 효소를 분비하는 미세아교세포로 분화함으로써 중추신경계(CNS)의 병변을 완화합니다.

Mucopolysaccharidosis Type I (MPS I) Understanding and Treatment Algorithm

Mucopolysaccharidosis Type I (MPS I) Overview and Diagnosis

MPS I is a rare, inherited lysosomal storage disorder caused by a deficiency of the enzyme alpha-L-iduronidase (IDUA), which is crucial for breaking down glycosaminoglycans (GAGs) like dermatan sulfate and heparan sulfate. The accumulation of these substances leads to progressive cellular and tissue dysfunction, affecting multiple organ systems, including the skeletal, cardiovascular, respiratory, and nervous systems.

MPS I diagnosis involves GAG analysis, enzyme assays, and genetic testing, enabling early treatment, prognosis assessment, and genetic counseling. Screening programs support early detection, while comprehensive evaluations- such as pulmonary function tests, polysomnography, audiometry, ocular exams, skeletal imaging, and cognitive assessments aid in disease monitoring. Newborn screening and molecular testing play a crucial role in optimizing patient management and improving long-term outcomes.

Mucopolysaccharidosis Type I (MPS I) Treatment Landscape

Treatment of MPS I is guided by disease severity, with hematopoietic stem cell transplantation (HSCT) recommended for severe cases particularly in young children due to its ability to preserve cognitive function, while enzyme replacement therapy (ERT) primarily addresses somatic symptoms. However, both approaches have limitations, especially in managing skeletal manifestations, making early intervention critical for improved outcomes. The current standard therapy, laronidase (ALDURAZYME), remains constrained in efficacy, driving the development of next-generation treatments. Emerging candidates such as OTL-203, Lepunafusp alfa (JR-171), and Iduronicrin genleukocel-T (ISP-001) aim to provide more comprehensive disease control.

This section summarizes the cost of approved treatments, closest and most appropriate analogue selection for emerging therapies, and understanding of how pricing influences market access, adherence, and long-term uptake.

  • Pricing of Mucopolysaccharidosis Type I (MPS I) Approved Drugs

Laronidase (ALDURAZYME), priced at approximately USD 680,000 annually, is highlighted in the Medicaid Managed Care Organization (MCO) FFY 2022 Drug Utilization Review (DUR) Annual Report as a new non-preferred drug, in alignment with Fee-for-Service (FFS) policies and established class criteria. While ALDURAZYME is approved for the treatment of conditions such as mucopolysaccharidosis, its high cost contributes to it not always being considered a first-line or readily accessible option. As a result, its use may require additional approval steps, including prior authorization, and may involve higher cost-sharing for beneficiaries. This classification is intended to promote the use of more cost-effective alternatives while still ensuring access to necessary therapies when clinically appropriate.
