Brief Summary:
The goal of this long-term extension (LTE) study is to evaluate the safety and efficacy of pegtibatinase in patients with classical homocystinuria (HCU). Patients who are active in the Phase 1/2 COMPOSE study or those who complete the 24 weeks of treatment in the Phase 3 HARMONY are eligible to participate.
Participants will be in this clinical study for up to about 13 months including:
* a treatment period of up to 104 weeks
* a 4-week safety follow-up period

Detailed Description:
Overall Design:
This is a global, multicenter, single-arm, open-label study. Participants who meet all eligibility criteria may transition from other pegtibatinase studies and enroll into this LTE study for long-term safety, efficacy, and clinical assessments of pegtibatinase treatment.
All participants will follow a protocol of self-administration of pegtibatinase unless exempted. During the ENSEMBLE study, an optional protein tolerance modification (PTM) sub-study will also be conducted for eligible participants.
