Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 3 multicenter trial in 2 parts to evaluate the long-term safety and efficacy of navenibart in adult and adolescent participants with hereditary angioedema (HAE) who participated in STAR-0215-301 (NCT06842823; ALPHA-ORBIT). Part 1 provides all participants with navenibart in a dose-controlled fashion; Part 2 introduces a personalized dosing option (PDO) for participants based on individual needs.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

In Part 1, adult participants who completed STAR-0215-301 and received navenibart will maintain their fixed dosing regimen from STAR-0215-301, whereas those who were randomized to placebo in STAR-0215-301 will receive navenibart 600 mg Q3M. In Part 2, adult participants may move among dosing regimens via the personalized dosing option (PDO) based on their individual needs. Adult participants who did not complete STAR-0215-301 may be eligible to enroll in Part 2 of STAR-0215-302 if they meet certain criteria. Adolescent participants will continue to receive their fixed dosing regimen from STAR-0215-301 until they turn 18 years of age.
Primary Study Purpose

Blinding Strategy

NONE

All participants will knowingly receive navenibart, however participants, care providers, investigators, and outcome assessors will be blinded to their treatment arm for a duration specific to the individual.
