MarketVue®: Homocystinuria
The MarketVue®: Homocystinuria market landscape report combines primary (KOL interviews) and secondary market research to empower strategic decision-making and provide a complete view of the market.Every MarketVue® includes a disease overview, epidemiology (US and EU5), current treatment, unmet needs, pipeline and access and reimbursement chapter.
Topics covered in this report:
• Disease overview: Review the disease pathophysiology and potential druggable targets
• Epidemiology: Understand prevalence, diagnosed and drug-treated prevalence of the population and key market segments
• Current treatment: Understand the treatment decision tree and strengths and weaknesses of current on-label and off-label treatment
• Unmet needs: Identify opportunities to address treatment or disease management gaps
• Pipeline analysis: Compare current and emerging therapy clinical development strategy; their performance on efficacy, safety, and delivery metrics; and their potential to address unmet needs
• Value and access: Review the evidence needed to assess and communicate value to key stakeholders (e.g., providers, payers, regulators) and learn what competitors have done or are doing

Key takeaways from the report:
Classic homocystinuria (HCU) is a rare, inherited metabolic disease resulting from cystathionine beta-synthase deficiency. When left untreated or poorly managed, HCU is associated with severe symptoms such as:
• Developmental delays
• Stroke
• Bone weakness or deformities
• Lens dislocation
• Increased risk of blood clots
Betaine is the only FDA-approved treatment for homocystinuria, however, according to REACH Market Research’s MarketVue® assessment, medical geneticists state that its efficacy is limited in reducing total plasma homocysteine levels (tHcy), the primary goal of treatment. HCU patients who are pyridoxine-responsive are well managed with pyridoxine, however, most HCU patients are pyridoxine partial or non-responsive, and these patients represent the population for a which there is a large unmet need for efficacious tHcy lowering treatments.
Medical geneticist, U.S.: ""I think everybody who isn’t pyridoxine responsive is unhappy because they’re not getting where they need to go.""
Medical geneticists interviewed by REACH are excited about the prospect of ERTs. The HCU pipeline contains two ERTs:
• Travere Therapeutics’ human-modified PEGylated cystathionine beta-synthase – pegtibatinase
• Aeglea BioTherapeutics’ human engineered PEGylated cystathionine gamma-lyase inhibitor – pegtarviliase
Medical geneticists report that preliminary results from Travere’s clinical trials for pegtibatinase, showing a 55% reduction in tHcy, are promising.
Pooja Patel, Analyst at REACH: ""Physicians hope that emerging ERTs will allow pyridoxine partial and non-responsive patients to liberalize their diet. Although current treatments can lower tHcy for pyridoxine partial and non-responsive patients, they require strict monitoring of dietary protein intake, which is nearly impossible for most patients to sustain.""
