New Triple Combination Therapy in Newly Diagnosed Type 2 Diabetes
Combination Therapy With Tirzepatide, Empagliflozin and Pioglitazone Versus Standard Therapy in Newly Diagnosed Type 2 Diabetes: a Multi-center Randomized Controlled Trial
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:
- To compare efficacy of the triple combination therapy against standard therapy in achieving type 2 diabetes remission in patients newly diagnosed with T2DM.
- 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:
- Take new triple combination therapy or a standard therapy every day for 6 months
- Visit the clinic once every 0.5-1 month for checkups and tests
- Keep a diary of their fingertip blood glucose and adverse events

Experimenteel: Group A (triple combination intensive therapy group)
Tirzepatide, empagliflozin, and pioglitazone treatment.
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.

EQ-5D-5L vragenlijsten, beoordeling van de kwaliteit van leven. De EQ-5D-5L bestaat in wezen uit 2 pagina's: het EQ-5D-beschrijvende systeem en de EQ Visual Analoge Scale (EQ VAS). Het beschrijvende systeem omvat vijf dimensies: mobiliteit, zelfzorg, gebruikelijke activiteiten, pijn/ongemak en angst/depressie. Elke dimensie heeft 5 niveaus: geen problemen, lichte problemen, matige problemen, ernstige problemen en extreme problemen. De EQ VAS registreert de zelf beoordeelde gezondheid van de patiënt op een verticale visuele analoge schaal waar de eindpunten zijn gelabeld 'de beste gezondheid die u zich kunt voorstellen' en 'de slechtste gezondheid die u zich kunt voorstellen'. De VAS kan worden gebruikt als een kwantitatieve maatstaf voor de gezondheidsresultaten die het eigen oordeel van de patiënt weerspiegelt. |
