Population: included in per protocol

Occurence of any of the following predetermined study stopping criteria, which will trigger an immediate pause on enrollment: 1. Death of a participant considered related to study drug 2. One or more participants experience an Serious Adverse Event (SAE) or Grade 4 Adverse Event (AE) or a persistent (upon repeat testing) Grade 4 laboratory abnormality that is determined to be related to study drug 3. Three or more participants experience a Grade 3 or greater AE of the same type (as per medical judgement) that is determined to be related to study drug 4. Three or more participants experience a persistent (upon repeat testing) Grade 3 laboratory abnormality related to the same laboratory parameter and considered to be related to study drug 5.
