Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the efficacy and safety of liraglutide produced by CinnaGen company and Novo Nordisk liraglutide (Victoza®) in subjects with type II diabetes. Patients with Type II diabetes treated with two oral glucose-lowering agents for ≥ 3 months, aged between 30 to 65 years, HbA1c equal or greater than 7.5 and lower than 10, and BMI between 25 to 45 were included in this study.

This study is a phase III, randomized, two-armed, parallel, double-blind, active-controlled, and non-inferiority clinical trial. Patients who enter the trial will be randomly allocated (1:1 ratio) to receive subcutaneous 1.8 mg daily injections of either Victoza® or CinnaGen-liraglutide. Doses of liraglutide will be up-titrated from 0.6 mg/day in the first week to 1.2 mg/day in the second, third and fourth weeks up to 1.8 mg/day from the beginning of the fifth week. Patients continue to receive 1.8 mg/day liraglutide until the end 26th week.

The primary objective of this study is to assess non-inferiority of CinnaGen-liraglutide to reference liraglutide in terms of efficacy in patients with T2D. The secondary objectives of this study are to further compare the efficacy of CinnaGen-liraglutide to reference liraglutide and to assess the safety of CinnaGen-liraglutide to reference liraglutide.

Detailed Description

The purpose of this study is to compare the efficacy and safety of liraglutide produced by CinnaGen company with Novo Nordisk liraglutide (Victoza®) in subjects with type II diabetes. Patients with Type II diabetes treated with two oral glucose-lowering agents for ≥ 3 months, aged between 30 to 65 years, HbA1c equal or greater than 7.5 and lower than 10, and BMI between 25 to 45 will be included in this study. This study is a phase III, randomized, two-armed, parallel, double-blind, active-controlled, and non-inferiority clinical trial. Patients who enter the trial will be randomly allocated (1:1 ratio) to receive subcutaneous 1.8 mg daily injections of either Victoza® or CinnaGen-liraglutide. Doses of liraglutide will be up-titrated from 0.6 mg/day in the first week to 1.2 mg/day in the second, third and fourth weeks up to 1.8 mg/day from the beginning of the fifth week. Patients continue to receive 1.8 mg/day liraglutide until the end of 26th week.

Physical examinations and vital signs will be evaluated for patients at baseline, and at weeks 4, 8, 12 and 26 visits. Laboratory parameters will be assessed at baseline, week 12 and 26. The incidence of adverse events will be evaluated based on patients' reports, vital signs, physical examinations, and laboratory tests.

Before initiation, the trial will be reviewed by food and drug administration of Iran. The protocol, electronic case report form (eCRF), information for patients and informed consent form will be submitted to the ethics committees responsible for review and approval purposes, according to national regulatory guidelines.

In this study, no patient will be recruited without informed consent. All the informed consent forms which will be signed by the patients will have two copies so that patients can receive a copy of it.

Determination of sample size:

Group sample sizes of 120 and 120 achieve 80% power to detect non-inferiority using a one-sided, two-sample t-test with a non-inferiority margin of -0.4. The true difference between the means is assumed to be zero. The significance level (alpha) of the test is 0.025. The data are drawn from populations with standard deviations of 1.1 and considering a drop-out rate of 20% total sample size required is 300 patients.

Data Quality Assurance:

CinnaGen Company conducts clinical trials according to procedures that incorporate the ethical principles of GCP. Accurate and reliable data collection is assured by verification and cross-check of the eCRFs against the patient's records by clinical monitors, and the maintenance of a drug-dispensing log by the center.

CRO coordinators and sponsor attend the SIV (Site Initiation Visit) meetings. Protocol and GCP principles will be reviewed by coordinating investigator of each site, and also the needed information for completing eCRF forms will be explained.

Monitoring by CRO is performed in 30% and 70% of study progress and at the end of the study. In the monitoring sessions some sponsor personnel audit the process. During the monitoring process, CRO coordinator checks all eCRFs and confirms them to the source documents, and for required cases, the query form will be filled out.

The temperature of the refrigerator containing the medicines is checked and recorded by data logger which will be monitored regularly by the auditor.

CRO coordinator will verify drug accountability data and information about the proper time for patients' injections, and sponsor staff rechecks it.

After monitoring, problems are reported by monitor and auditor to the trial centers.

Blinding:

In order to prevent the influence of knowing intervention group on study results, the patients and those who assess the study outcomes will remain unaware of allocation to test- or reference-liraglutide.

For this purpose, patients and caregivers will be masked to allocated treatment by making reference and test products indiscernible by appearance. Medicines will be provided in a similar dosage form labeled with a unique code.

It should be noted that CRO personnel who enter data into eCRF and database and also the sponsoring personnel who monitor data entry are blinded. The study is double-blind and situations that might warrant breaking the code are defined in the protocol and include serious adverse events.
