Brief summary

This is a single-arm, open-label, multicenter, ascending dose Phase 1 trial that will enroll participants 18 to 75 years of age with dyslipidemias that are refractory to available treatments.

Interventions

This is a single-arm, open-label, multicenter, ascending single-dose Phase 1 study. Subjects will receive a single dose of CTX310 via intravenous (IV) infusion. Planned ascending doses levels will be 0.1 mg/kg, 0.3 mg/kg, 0.6 mg/kg, 0.8 mg/kg. Participants will receive only one dose.
