Note: subjects who are not heterosexually active at screening must agree to utilize a highly effective method of birth control if they become heterosexually active during their participation in the study. •Women of childbearing potential must have a negative urine beta human chorionic gonadotropin (beta hCG) pregnancy test at screening and baseline (predose, Day 1). •Willing and able to adhere to the prohibitions and restrictions specified in this protocol •Subjects must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study. •To participate in the optional pharmacogenomic component of this study, subjects must have signed the informed consent form for pharmacogenomic research indicating willingness to participate in the pharmacogenomic component of the study (where local regulations permit). Refusal to give consent for this component does not exclude a subject from participation in the clinical study. •Adequate compliance with the run-in period study procedures, including performance of the SMBG measurements (completed at least 3 or more SMBG measurements per week) with appropriate diary entries, and ≥80% compliance (by pill count) with single-blind placebo capsules
