This is a study to evaluate the impact and efficacy of Efsubaglutide Alfa injection 3mg QoW on the treatment of type 2 diabetes patients with poor glycemic control after dietary and exercise intervention. Primary objective: To evaluate the effect and role of continuous treatment with 3mg of Efsubaglutide Alfa QoW and 1mg of Efsubaglutide Alfa QW for 12 weeks on HbA1c in T2DM patients with poor glycemic control after dietary and exercise intervention. Secondary objectives: 1. To evaluate the effect of continuous treatment with 3mg of Efsubaglutide Alfa QoW for 12 weeks on glucose variability (change in time in range (TIR) relative to baseline) in T2DM patients with poor glycemic control after dietary and exercise intervention. 2. To evaluate the effect of continuous treatment with 3mg of Efsubaglutide Alfa QoW for 12 weeks on drug exposure (relative to 1mg QW) in T2DM patients with poor glycemic control after dietary and exercise intervention. 3. To evaluate the effect of continuous treatment with 3mg of Efsubaglutide Alfa QoW for 12 weeks on fasting plasma glucose (FPG) in T2DM patients with poor glycemic control after dietary and exercise intervention.
