About this study
Official title: MB001-067 A PROSPECTIVE, DOUBLE BLIND, PLACEBO CONTROLLED, PARALLEL GROUP, RANDOMIZED TRIAL OF EXTENDED RELEASE EXENATIDE VERSUS PLACEBO (COHORT A) AND A PROSPECTIVE, SINGLE GROUP, OPEN-LABEL, BLINDED OUTCOME TRIAL OF EXTENDED RELEASE EXENATIDE (COHORT B) IN DIABETIC PATIENTS WITH TYPE 4 CARDIORENAL SYNDROME (EXTEND-CRS TRIAL) AMENDMENT 3
Among adult individuals with type 2 diabetes mellitus and at risk for heart failure with impaired relaxation of the heart mildly reduced kidney filtration function (Type 4 cardiorenal syndrome) this trial will evaluate the quantitative impact of 38 weeks of treatment with exenatide extended-release injections versus placebo. on a cardiac biomarker blood test score, cardiac fibrosis seen on magnetic resonance scanning, cardiac strain identified by ultrasonography and strain rate imaging, and a kidney urine biomarker score.
Read the detailed description
Primary Aim
Among adult individuals with type 2 diabetes mellitus (T2DM) and at risk for diastolic heart failure (DHF) and mildly reduced renal filtration function (Type 4 cardiorenal syndrome), to evaluate the quantitative impact on the MISS (myocardial injury summary score) cardiac biomarker score, cardiac fibrosis by MRI, cardiac strain by ultrasonography and strain rate imaging, and KISS (kidney injury summary score) kidney biomarker score after 38 weeks of treatment with exenatide extended-release or placebo.
Secondary Aim
To evaluate the inter-relationships between demographic, clinical, and biochemical variables (MISS score, KISS score) and of progressive cardiac fibrosis as assessed by MRI, strain-rate imaging, and in adult individuals with T2DM and at risk for DHF (Type 4 cardiorenal syndrome).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing BYDUREON in people with Type 2 Diabetes Mellitus and Chronic Kidney Disease, run by Baylor Research Institute at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Galectin-3 (time frame: 38 weeks). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02251431, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Feb 2026.
