Diabetic NephropathiesPhase 3IDEAL-2NCT03216564
An Intervention to Examine the Effect of Vitamin D on Urine Protein Levels in Type 2 Diabetes
A Phase 3 study testing Calcitriol in people with Diabetic Nephropathies, run by Hamad Medical Corporation at 1 site in Qatar.
Trial summary
Diabetic kidney disease (nephropathy) develops in nearly 40% of patients with type 2 diabetes mellitus. Diabetic nephropathy is caused by damage to the small blood vessels in the kidneys due to uncontrolled blood sugar levels, which mean that the kidneys become less effective at filtering urine.

About this study
Official title: Intervention Using Vitamin D for Elevated Urinary ALbumin in Diabetes (IDEAL-2)
Diabetic kidney disease (nephropathy) develops in nearly 40% of patients with type 2 diabetes mellitus. Diabetic nephropathy is caused by damage to the small blood vessels in the kidneys due to uncontrolled blood sugar levels, which mean that the kidneys become less effective at filtering urine. This is associated with albuminuria (protein in the urine). Treatment with some drugs reduces the loss of albumin through the urine and delays disease progression. There is increasing evidence that vitamin D could also be important in management of diabetic kidney disease. The aim of this study is to investigate the efficacy and safety of a combined regimen of calcitriol (active vitamin D) and established drugs for diabetic kidney disease.
Read the detailed description
The investigators propose to test the efficacy and safety of a combined regimen of calcitriol and angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) in type 2 diabetes subjects with albuminuria. In the proposed study, the bioactive form of vitamin D (calcitriol) is being used for its ability to synergize with ACEI or ARB and prevent renal disease progression. The study expands on preliminary studies demonstrating a reduction in proteinuria with vitamin D analogue treatment, in subjects with both diabetic as well as non-diabetic kidney disease.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Calcitriol in people with Diabetic Nephropathies, run by Hamad Medical Corporation at 1 site in Qatar.
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 5 inclusion and 14 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: status not confirmed, as of the sponsor's last update on 6 Sep 2018. 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 Qatar. 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Shahrad Taheri, MB BS PhD (0097444928998, szt2004@qatar-med.cornell.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Urinary albumin creatinine ratio (ACR) measured biochemically (time frame: 26 weeks). 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 NCT03216564, which also lists 1 linked publication.
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 6 Sep 2018.
