• In addition, the establishment of rare disease registries, collaboration between academic centers, and increasing investment in pediatric genomics are strengthening the foundation for long-term market growth. These efforts are improving patient tracking, therapy outcomes, and clinical trial recruitment, particularly in specialized hospital settings
• As diagnostic capabilities improve and clinical interest grows, the such aslihood of earlier diagnosis and more effective intervention increases, further boosting the demand for specialized treatments and care protocols

Restraint/Challenge

High Treatment Costs and Limited Patient Pool

• Despite promising advancements, the high cost of diagnosis, treatment, and long-term care for Alagille syndrome poses a major barrier to widespread market penetration. Genetic testing, specialist consultations, and orphan drugs often come at a premium, placing financial strain on patients and healthcare systems, especially in low- and middle-income countries
• For instance, therapies under orphan drug status, while potentially life-changing, may cost tens of thousands of dollars annually, limiting accessibility even with partial reimbursement support
• Moreover, the extremely low prevalence of Alagille syndrome restricts the patient pool for clinical trials and commercial scalability, making it financially risky for some companies to pursue product development. Delayed diagnosis due to symptom overlap with other pediatric liver diseases further complicates patient identification
• To overcome these challenges, there is a pressing need for expanded rare disease insurance coverage, international patient registries, cost-effective diagnostic solutions, and cross-border research collaborations
• Reducing the economic burden and improving accessibility will be crucial to unlocking the full potential of the Alagille syndrome market over the coming years

The new formulation offers enhanced patient convenience, particularly for older children and adults who may struggle with liquid forms. Mirum announced that the tablet will be commercially available starting June 2025 through its Mirum Access Plus program, aiming to expand treatment adherence and access
• In June 2024, The FDA expanded the label for Livmarli (maralixibat oral solution), previously approved for ALGS, to include treatment for PFIC patients. The label expansion follows results from the global Phase 3 MARCH study, which demonstrated significant efficacy in reducing pruritus and improving bile acid levels in affected children. This marks another regulatory milestone for Mirum Pharmaceuticals, reinforcing its leadership in rare pediatric cholestatic liver diseases
• In November 2023, The Alagille Syndrome Alliance (ALGSA) announced the formation of the Alagille Syndrome Research Network (ASRN) to foster international collaboration between clinicians, researchers, biopharmaceutical companies, and patient advocates. This strategic initiative is designed to accelerate translational research, facilitate data sharing, and drive innovation in treatment development, ultimately aiming to improve outcomes and quality of life for ALGS patients worldwide
• In October 2023, A pivotal study from Children’s Hospital Colorado provided long-term evidence that Livmarli (maralixibat) not only reduces pruritus but also improves liver biomarkers and enhances transplant-free survival in pediatric ALGS patients. The study underscores the clinical significance of early and sustained treatment with maralixibat, suggesting it may delay or prevent the need for liver transplantation in severe cases
• In June 2023, The FDA approved Odevixibat (Bylvay), an ileal bile acid transporter (IBAT) inhibitor from Albireo Pharma, for the treatment of cholestatic pruritus in children aged 12 months and older with ALGS.
