Exclusion Criteria:

any investigational therapy within 14 days or 5 half-lives (whichever is shorter)
prior to first dose of study drug; hydroxyurea is permitted up to the day before

- Vaccinated with live, attenuated vaccines within 4 weeks of first dose of study drug
- Recent culture-documented infection requiring systemic intravenous treatment that was
completed =< 7 days before the first dose of study drug or any uncontrolled active
systemic infection; fever of unknown origin is not an exclusion criterion, as this may
be disease-related

excluded; subjects with HIV must have a CD4 count at or above the institutional lower
limit of normal and not taking prohibited CYP3A strong inhibitors

- Any life-threatening illness, medical condition, or organ system dysfunction,
including but not limited to, ongoing or active infection, symptomatic congestive
heart failure, unstable angina pectoris, cardiac arrhythmia, active autoimmune
disorder, or psychiatric illness/social situations that, in the investigator's
opinion, could compromise the subject's safety or put the study outcomes at undue risk
