Type 2 Diabetes Mellitus: what the trials found

Semaglutide treatment was associated with significant reductions in body weight (ranging from -4.0% to -13.5%; p<0.0001) and a high proportion of participants achieving at least a 5% reduction in body weight (p<0.0001) 2. In addition, Semaglutide was associated with improvements in treatment satisfaction scores (DTSQc) and significant reductions in daily insulin doses for some patients 6.

Semaglutide did not show statistically significant changes in kidney oxygenation (Cortex or Medulla) or global kidney perfusion 3. Insulin Icodec was associated with a significant reduction in HbA1c (-1.23; p<0.0001) and recorded 13 instances of clinically significant hypoglycemia 5.

Testosterone gel was associated with measurable changes in bone strength as determined by Finite Element Analysis (p<0.05) 1.

Recent results — preliminary, needs further review

  • NNC0480-0389 was associated with significant reductions in HbA1c (-1.1 to -2.3; p<0.0001), body weight (-4.3% to -13%; p<0.0001), and stable total cholesterol levels 8.
  • Dietary interventions were associated with significant improvements in glycemic control as measured by blood sugar values (p<0.001) 12, while the DASH4D diet was associated with significant changes in systolic blood pressure (p<0.001) 13.
  • The FUSION closed-loop glucose control system showed 97.25% of glucose values within the target range of 70-180 mg/dL 17.
  • An initial insulin dosing calculator was associated with a significant reduction in clinical hyperglycemia (p=0.0005) 16.

For the clinician treating this condition

  • Semaglutide demonstrates consistent efficacy in weight reduction and improving patient treatment satisfaction while reducing insulin requirements.
  • Insulin Icodec is associated with significant HbA1c reduction, though clinical monitoring for hypoglycemia is noted.
  • NNC0480-0389 shows promise for concurrent management of HbA1c and body weight.
  • Non-pharmacological interventions including specific diets (DASH4D) and technology-based systems show measurable impacts on blood pressure and glycemic range maintenance.
