Background: Oral semaglutide GLP1 receptor agonist is coformulated for better absorption compared to prior injectable semaglutide. Phase 2 open label, dose escalation randomized clinical trials of semaglutide and liraglutide investigating the dose-response relationship between the two. DPP-4 inhibitor produces a smaller glycemic reduction and minimal weight reduction through effect of endogenous GLP-1 receptor activity, while GLP-1RAs yield greater efficacy related to the pharmacological levels of these agonists stimulating GLP-1 receptor activity.
Design & Methods | Objective | IND | Treatment Arms | Endpoints | Results & Conclusions |
Phase 2 RCT placebo controlled dose findings | Dose Findings Analysis of Oral Semaglutide | Oral Semaglutide or Placebo | 2.5 mg QD/ Placebo; 5.0 mg QD/ Placebo, 10 mg QD/ Placebo; 20 mg QD/ Placebo; 40 mg QD/ Placebo | Changes in HbAlc in 26 weeks: Weight Reduction | HbAlc mean 7.9%; 2 to 7 kg Weight reduction |
Phase 2 RCT with Dose Escalation | To investigate the dose-response relationship of semaglutide versus placebo and open-label liraglutide in terms of glycemic control in patients with type 2 diabetes | Injectable Semaglutide | 0.1 to 0.8 mg QW with dose escalation 0.4 to 0.8 mg; 1.6 mg for 12 weeks | Changes in HbAlc in 12 weeks: Weight Reduction | 1.7% HbAlc reduction; 4.8 kg weight reduction; (1.6 mgE. P< 0.001 vs Placebo) |
