Clinical Trial Summary

This is a Phase 1, first in human (FiH), randomized, double-blind, placebo-controlled, single ascending dose (SAD) and multiple ascending dose (MAD) study to investigate the safety, tolerability, PK and PD of DD01 administered by subcutaneous (SC) injection in overweight/obese subjects with type 2 diabetes (T2DM) and nonalcoholic fatty liver disease (NAFLD).

The study will be conducted in 2 Parts (Part A and B), with up to 8 cohorts included in each part (Part A; Cohorts A1 to A8 and Part B; Cohorts B2 to B8).

Description:

Part A (SAD):

In Part A, subjects will receive a single dose of study drug, and the safety and efficacy of DD01 will be evaluated in overweight/obese subjects with T2DM.

Part B (MAD):

In Part B, subjects will receive once-weekly doses of the study drug for 4 weeks, and the safety and efficacy of DD01 will be evaluated in overweight/obese subjects with T2DM and NAFLD.
