Drug Approval
Drug development for homocystinuria is limited to just three clinical-stage products, two of which are injectable enzyme replacement therapies (ERTs).
NEWTON, Mass., April 11, 2023 /PRNewswire/ -- 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
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
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.
