Triple Combination Therapy Effective for Drug-Naive Type 2 Diabetes Patients, shows new Study

The primary measure of success was the percentage of patients achieving an HbA1c level below 6.5% without experiencing hypoglycemia, gaining 5% or more in weight, or needing to stop medications due to adverse events by the 104-week mark.

The study led to the following findings:

• HbA1c reduction from baseline at week 104 was similar between the groups (the least squares mean change was −2.56% in the TCT group vs. –2.75% in the SAT group).
• The primary outcome was achieved in 39.0% and 17.1% of the TCT and SAT groups, respectively, with a risk difference of 22.0.
• HbA1c level less than 6.5% at week 104 was 46.3% in both the TCT and SAT groups, whereas the incidence of hypoglycemia, weight gain, or discontinuation of drugs was 16.7% and 62.0% in the TCT and SAT groups, respectively.
• TCT was well-tolerated and had fewer adverse events than SAT.

In conclusion, although each drug's glycemic efficacy in the triple combination therapy was modest, the drug combination led to a 2-year durable glycemic efficacy, with greater than a 2.5% reduction in A1c levels from baseline. Overall, the study results suggest a novel strategy for initial combination therapy in newly diagnosed T2D patients.

In addition, the initial TCT was linked with an improvement in multiple cardiovascular risk factors compared with SAT.
