ZODIAC Trial Summary
This trial will test if two drugs given together can help reduce albuminuria (a protein in urine) more than either drug given alone.
Who is the study for?
Adults aged 18-75 with type 2 diabetes, HbA1c ≥6.0%, and kidney issues shown by high albumin in urine can join this trial. They must be on stable heart medication for a month and not have type 1 diabetes, severe non-diabetic kidney disease, very high blood sugar, or conditions like heart failure that could risk their safety or affect results.Check my eligibility
What is being tested?
The study tests if Zibotentan (a drug blocking certain receptors) combined with Dapagliflozin (a drug reducing sugar absorption in kidneys) better reduces protein leakage into urine than either alone without causing fluid retention. Participants will randomly receive one of the drugs alone, both together, or a placebo.See study design
What are the potential side effects?
Possible side effects include fluid retention leading to swelling (especially with Zibotentan), low blood pressure, dizziness when standing up due to dehydration risks from Dapagliflozin, urinary tract infections, and potential allergic reactions.

2Treatment groups
Experimental Treatment
Group I: Treatment order 2Experimental Treatment4 Interventions
Subjects will start with 4 weeks of dapagliflozine in treatment period one, then 4 weeks of zibotentan during treatment period two. The order of the first two treatment periods is random which means that patients can start with either dapagliflozine or zibotentan. Then in treatment period three, patients are randomized to either either placebo or dapagliflozin for 2 weeks followed immediately by 4 weeks of both zibotentan and dapagliflozin. Between treatment periods there is a 4-week wash-out.
Group II: Treatment order 1Experimental Treatment4 Interventions
Subjects will start with 4 weeks of placebo in treatment period one, then 4 weeks of zibotentan during treatment period two. The order of the first two treatment periods is random which means that patients can start with either placebo or zibotentan. Then in treatment period three, patients are randomized to either either placebo or dapagliflozin for 2 weeks followed immediately by 4 weeks of both zibotentan and dapagliflozin. Between treatment periods there is a 4-week wash-out.
