Cadisegliatin as Adjunctive Therapy to Insulin in Participants With Type 1 Diabetes Who Are Using Hybrid Closed Loop (HCL) Systems (Hybrid CATT1)

22. Mai 2026 aktualisiert von: vTv Therapeutics

Hybrid CATT1: Hybrid Closed Loop Insulin Pumps With Cadisegliatin as Adjunctive Treatment in Patients With Type 1 Diabetes A Phase 2a Double Blind Randomized Cross-Over Study

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 manager their diabetes. Patients 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 1-2 weeks followed by the second double-blind treatment period of 6 weeks where the patient will cross-over to the treatment arm that they did not receive in the first treatment period.

Detaillierte Beschreibung

TTP399-206 is a 20 week, Phase 2a trial designed to evaluate efficacy and safety of cadisegliatin in participants with T1D who are using hybrid closed loop (HCL) systems to manage their condition to gather preliminary data to understand how cadisegliatin performs in an HCL setting.

Experimental: Cadisegliatin 800 mg QD: Double Blind, Randomized Crossover Trial Design
If a patient is randomized to receive cadisegliatin 800 mg QD as an adjunctive therapy to their insulin treatment in the first double-blind treatment period of 6 weeks, there will then be a washout period of 1-2 weeks followed by the second double-blind treatment period of 6 weeks where the patient will cross-over to the placebo QD along with their insulin treatment arm
Cadisegliatin is an orally bioavailable small-molecule glucokinase activator, adjunctive therapy to insulin
