prior treatment was discontinued for intolerance.
Exclusion Criteria:
- Pregnant or breastfeeding women. NOTE: Women of childbearing potential must have a

surface antigen/ positive Hepatitis C antibody or detectable viral load by PCR).
Patients with positive antibody but negative viral loads will be eligible for study
participation but will require appropriate prophylaxis.
NOTE: Hepatitis B and C testing are required.
- Screening rate-corrected (using Friderica's correction) QT interval (QTcF) must not be

- Receipt of live attenuated vaccine within 30 days before the first dose of study
treatment.
- HbA1c > 8.5% at Screening
