Summary

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)

Conditions

  • Non-Transfusion Dependent Beta-Thalassemia (NTDT)
