What is the purpose of this trial?

TTP399-206 is a Phase 2a multicenter double blind cross over randomized study of cadisegliatin in participants with T1D using hybrid closed loop systems to manage their diabetes. Participants using a hybrid closed loop insulin pump to manage their diabetes will be randomized to either receive blinded cadisegliatin 800 mg QD as an adjunctive therapy to their insulin treatment or placebo QD along with their insulin treatment. The trial begins with a screening period of up to 2 weeks, followed by a device training and insulin adjustment period of 1-2 weeks leading into the first double-blind treatment period of 6 weeks. There will then be a washout period of 2 weeks followed by the second double-blind treatment period of 6 weeks where the participants will cross-over to the treatment that they did not receive in the first treatment period.

What Are the Treatments Tested in This Trial?

Interventions

  • Cadisegliatin

Trial Overview

The study tests whether adding cadisegliatin (800 mg once daily) to regular insulin therapy helps control blood sugar better than a placebo in people with type 1 diabetes using advanced insulin pumps. Each participant tries both treatments during different periods of the trial.
