Condition(s) studied
Diabetes Mellitus
Investigational drug(s) / intervention(s)
Group A (triple combination intensive therapy group)Group B (standard therapy group)
Group A (triple combination intensive therapy group): 1\) Initiate with Tirzepatide 2.5 mg once weekly (qw) + Empagliflozin 10 mg once daily (qd) + Pioglitazone 15 mg once daily (qd); 2) After 1 month, adjust Tirzepatide to 5.0 mg qw + Empagliflozin 20 mg qd + Pioglitazone 30 mg qd; 3) After 1 month, adjust Tirzepatide to 7.5 mg qw + Empagliflozin 20 mg qd + Pioglitazone 30 mg qd. 4) After 1 month, adjust Tirzepatide to 10.0 mg qw + Empagliflozin 20 mg qd + Pioglitazone 30 mg qd; 5) If blood glucose remains uncontrolled after 1 month, add basal insulin therapy.
Group B (standard therapy group): 1\) Initiate with Metformin monotherapy, titrate to the target dose of 1000 mg twice daily (bid) within 1 month or to the maximum tolerated dose (if Metformin is not tolerated, switch to Linagliptin 5 mg qd); 2) After 1 month, if blood glucose is not controlled, add a second antidiabetic drug, Empagliflozin 20 mg qd; 3) After 1 month, if blood glucose remains uncontrolled, add Tirzepatide 2.5 mg qw; 4) After 1 month, if blood glucose remains uncontrolled, adjust Tirzepatide to 5.0 mg qw; 5) After 1 month, if blood glucose remains uncontrolled, adjust Tirzepatide to 7.5 mg qw; 6) After 1 month, if blood glucose remains uncontrolled, adjust Tirzepatide to 10.0 mg qw.
Study summary
The goal of this clinical trial is to learn the efficacy of combination therapy with tirzepatide, empagliflozin and pioglitazone versus standard therapy in newly diagnosed type 2 diabetes. The main objectives to achieve are:
1. To compare efficacy of the triple combination therapy against standard therapy in achieving type 2 diabetes remission in patients newly diagnosed with T2DM.
2. To compare the effects on β-cell function and glycemic control of the triple combination therapy against standard therapy in patients newly diagnosed with T2DM Researchers will compare drug new triple combination therapy with tirzepatide, empagliflozin, and pioglitazone to standard therapy (metformin based treatment) to see if new triple combination therapy works better in achieving type 2 diabetes remission.
Participants will:
1. Take new triple combination therapy or a standard therapy every day for 6 months
2. Visit the clinic once every 0.5-1 month for checkups and tests
3. Keep a diary of their fingertip blood glucose and adverse events
