RECRUITING

A Study to Test the Safety, Tolerability, and Efficacy of an Antibody, REGN7999, Injected Under the Skin for the Treatment of Iron Overload in Adult Participants With Non-Transfusion Dependent β-thalassemia, Using MRI Scans to Measure Iron Levels in the Body

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This study is researching an experimental drug called REGN7999 (called "study drug"). The study is focused on patients with non-transfusion dependent beta-thalassemia. The aim of the study is to see how safe and effective the study drug is. The study is looking at several other research questions, including: * Whether the study drug lowers extra iron levels in the body * What side effects may happen from taking the study drug * How much study drug is in the blood at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)

Official Title

A PHASE 2, TWO-PART, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, MULTICENTER STUDY TO EVALUATE THE EFFICACY, SAFETY, AND TOLERABILITY OF SUBCUTANEOUSLY ADMINISTERED REGN7999 (AN INHIBITOR OF TMPRSS6) IN PARTICIPANTS WITH IRON OVERLOAD DUE TO NON-TRANSFUSION DEPENDENT β-THALASSEMIA
