- Brief summaryRationale: Clinical practice guidelines recommend ACE-inhibitors or ARBs to all patients with diabetes and elevated albuminuria. Strikingly, 30 to 40% of patients do not respond to these first choice guideline recommended drugs. Previous cross-over studies showed that uptitrating the dose of the ACEi or ARB or rotation from ACEi to ARB (or vice versa) did not solve therapy resistance. These data suggest that patient factors in stead of drug factors determine individual drug response. Whether rotation to drugs from other drug classes improve drug response to therapy resistant patients is not prospectively investigated, but may be expected given the variable pathogenesis of diabetes and the supposedly different mechanisms of action of different albuminuria lowering drug classes. A better understanding on the individual response to different albuminuria lowering drugs may help to tailor optimal therapy.

Objective: To determine the individual albuminuria lowering response of four different albuminuria lowering drug classes in patients with type 2 diabetes and micro and macroalbuminuria.

Study design: A randomized, prospective, double blind, multicentre, crossover trial with a total duration of 48 weeks. Study population: Patients with type 2 diabetes of at least 18 years or older and elevated albuminuria (> 50 mg/g). Intervention (if applicable): Patients receive in random order 4 weeks of treatment with a angiotensin receptor blocker (telmisartan 80 mg/day), SGLT2 inhibitor (empagliflozin; 10 mg/day), DPP4 inhibitor (linagliptin 5 mg/day) and a glycosaminoglycan (sulodexide 200 mg/day) with 4-weeks wash-out periods in between. After the last treatment period patients will be re-reandomized to a 4-week treatment period to the drug that induced the strongest or least strong albuminuria-lowering response for that particular patient.

Main study parameters/endpoints: The main study endpoint is the proportion of patients in whom the drug selected in the fifth treatment period exerts the strongest or least strong albuminuria lowering effect compared to the drugs used in the other treatment periods for each individual. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: At the beginning and end of each treatment period blood is collected for clinical chemistry. Patients are requested to collect first morning void urine samples every 2 weeks throughout the study. Office blood pressure and body weight are monitored every 4 weeks. There are no direct benefits for the patients to be included and participation is on a free-will base.
