• Adequate liver function defined as ALT, AST, ALP, GGT, bilirubin within 1.5x institutional upper limit of normal
• Potassium, calcium, and magnesium within normal limits (PCZ cohort)
• Adequate renal function defined as eGFR levels within 1.5x the institutional upper limit of normal (only for KCZ cohort)
• Ability to swallow medication
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) for the duration of study participation.
