This is a Phase Ib, randomized, blinded, placebo-controlled, multiple ascending-dose study of the safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) effects of BFKB8488A in participants with Type 2 diabetes mellitus (T2DM) and participants with non-alcoholic fatty liver disease(NAFLD). A maximum of approximately 160 participants will be enrolled across multiple sites in the United States. Participants will be randomly assigned to receive study drug (active BFKB8488A or placebo). The study will consist of a screening period (up to 8 weeks), a 12-week treatment period, and a 6-week follow-up period. Participants may come to clinic for an optional pre-screening visit.
