Can a Lab-Made enzyme tame a rare genetic disorder?
Disease control Recruiting nowThis trial tests whether pegtibatinase, a lab-made version of the CBS enzyme, can safely lower homocysteine levels in people with classical homocystinuria (HCU), a rare genetic condition that causes harmful buildup of homocysteine and methionine. The study includes children and a…

New shot could tame rare metabolic disease
Disease control Recruiting nowThis Phase 3 trial tests pegtibatinase, an enzyme given as a shot, in 70 people aged 12–65 with classical homocystinuria. The goal is to see if it safely lowers high homocysteine levels when added to standard care. Participants receive either the drug or a placebo for 24 weeks.
