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

Tidsramme: Ved baseline, ved 6 måneders medisinering, og 3, 6 og 12 måneder etter seponering av medisiner

EQ-5D-5L-spørreskjemaer, vurdering av livskvalitet. EQ-5D-5L består i hovedsak av 2 sider: EQ-5D beskrivende system og EQ Visual Analogue Scale (EQ VAS). Det beskrivende systemet omfatter fem dimensjoner: mobilitet, egenomsorg, vanlige aktiviteter, smerte/ubehag og angst/depresjon. Hver dimensjon har 5 nivåer: ingen problemer, små problemer, moderate problemer, alvorlige problemer og ekstreme problemer. EQ VAS registrerer pasientens egenvurderte helse i en vertikal visuell analog skala der endepunktene er merket 'den beste helsen du kan forestille deg' og 'den verste helsen du kan forestille deg'. VAS kan brukes som et kvantitativt mål på helseutfallet som gjenspeiler pasientens egen vurdering. |
