Investigating insulin degludec and liraglutide in healthy Chinese individuals

A Randomized, Open-label, Two-period, Cross-over Trial to Evaluate the Single Dose Pharmacokinetics of Insulin Degludec/Liraglutide Injection Compared With Xultophy® in Healthy Chinese Subjects

This study is testing how a new combination of insulin and liraglutide works in healthy Chinese adults compared to an existing treatment.

Quick facts

• Study type: Interventional
• Enrollment: 44 (estimated)
• Ages: 18 Years to 45 Years

What this trial studies

This trial aims to compare the pharmacokinetics of a combination product of insulin degludec and liraglutide against Xultophy in healthy Chinese subjects. Participants will receive a single dose of the medications, and blood samples will be collected at various intervals to measure drug concentrations. The study will require participants to stay overnight at the trial site on certain days and attend for outpatient assessments as needed. The total blood volume collected will be less than 400 mL throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are healthy Chinese individuals aged 18 to 45 with a BMI between 19 and 26.

Not a fit: Patients with a history of allergies to the study medications or those with significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of insulin degludec and liraglutide pharmacokinetics, potentially leading to improved diabetes management strategies.

How similar studies have performed: While this specific combination has not been extensively tested in this population, similar pharmacokinetic studies have shown promising results in other demographics.
