Phase 2

Recruiting

• Conditions: Type 2 Diabetes
• Interventions: Drug: CPL207280; Drug: Placebo

• Registration Number: NCT05248776
• Lead Sponsor: Celon Pharma SA

Brief Summary

The planned study is to evaluate the efficacy, safety and pharmacokinetic (PK) properties of CPL207280 after multiple (14 days) administration in patients with type 2 diabetes.

Detailed Description

A double-blind, randomized, placebo-controlled, parallel-group study of 4 different doses of CPL207280 administered orally for 14 days. Approximately 80 participants will be randomized at a 1:1:1:1:1 ratio to 5 arms to receive Investigational Medicinal Product (IMP) or placebo.
