Clinical Trial Summary

The goal of this clinical trial is to determine the feasibility of remote clinical trial conduct in patients with type 2 diabetes and elevated albuminuria. The main questions it aims to answer are: - What is the feasibility (and advantages) of remote clinical trial conduct with multiple medications in patients with type 2 diabetes and elevated albuminuria? - What is the individual response to the SGLT2 inhibitor empagliflozin in urine albumin-creatinine ratio? - What is the individual response to the SGLT2 inhibitor empagliflozin in systolic blood pressure, body weight, eGFR, and fasting plasma glucose? - Can suboptimal treatment responses to empagliflozin be overcome by the addition or substitution with finerenone? Participants will collect all study data in the comfort of their own environments - First-morning void urine samples - Capillary blood samples - Blood pressure - Body weight Participants will be assigned to a 3-week treatment period with empagliflozin 10 mg/day. Based on the albuminuria response after 2 weeks, participants will be allocated to one of three treatment regimens after the 3-week treatment period with empagliflozin: - Continue empagliflozin for 4 more weeks (good response). - Continue empagliflozin for 4 more weeks and add finerenone 10 or 20 mg will be added for 4 weeks (moderate response). - Stop empagliflozin and start finerenone 10 or 20 mg for 4 weeks (no response)

Clinical Trial Description

Rationale: The treatment of cardiovascular and kidney-related complications associated with type 2 diabetes has made significant progress in recent years. Clinical trials have demonstrated the clinical benefits of sodium glucose co-transporter 2 (SGLT2) inhibitors and the selective non-steroidal mineralocorticoid receptor antagonist (MRA) finerenone. Guidelines from professional nephrology and cardiology associations now recommend the use of SGLT2 inhibitors and finerenone for all patients with type 2 diabetes and chronic kidney disease (CKD). Although guidelines recommend the use of these new drug classes for all patients, the adoption in clinical practice has been slow, with implementation barriers existing at the healthcare facility, physician, and patient levels. Despite the beneficial effects of these new drug classes on a population level, resulting in a reduction in the relative risks of cardiovascular and kidney outcomes, a high residual risk remains, which is closely associated with high levels of albuminuria. This remaining risk can, in part, be attributed to sub-optimal individual responses to SGLT2 inhibitors and finerenone. The investigators' previous research has demonstrated substantial variability in individual albuminuria responses to SGLT2 inhibitors and MRAs among patients, indicating that some patients benefit from SGLT2 inhibitors, others from finerenone, and yet another group requires a combination of both agents for optimal cardiovascular and kidney protection. To leverage technological advancements and evaluate drug efficacy and safety at an individual patient level, the investigators propose a pilot remote (home-based) clinical trial aimed at demonstrating the feasibility and advantages of conducting a remote clinical trial involving multiple medications to identify optimal therapy with the least pill burden for each patient. This trial will also assess patient experiences with data collection conducted remotely. This would potentially help (1) to facilitate the implementation of guideline-recommended treatments, (2) to optimize the guideline-recommended treatments for each individual, and (3) to evaluate individual drug responses and tailor therapy to each patient. Ultimately, the investigators' goal is to transition patient care from clinical settings (hospitals or general practitioner practices) to the home environment, making treatment regimen adjustments based on remotely collected data. This shift aims to minimize patient visits and enhance patient participation in optimizing their therapy in line with established guidelines. Objective: The primary objective is to determine the feasibility and advantages of remote clinical trial conduct with multiple medications in patients with type 2 diabetes and elevated albuminuria. The secondary objectives are to: - Determine the individual response to the SGLT2 inhibitor empagliflozin in urine albumin-creatinine ratio (UACR). - Determine the individual response to the SGLT2 inhibitor empagliflozin in systolic blood pressure, body weight, estimated glomerular filtration rate (eGFR), and fasting plasma glucose. - Assess if suboptimal treatment responses to empagliflozin can be overcome by the addition or substitution with finerenone. Main trial endpoints: The main trial endpoints are: - Questionnaire results: participants' perspectives toward the feasibility of participation in a trial at home with digital technologies. - Number and percentage of urine collections not received at the laboratory or unable to be analysed. - Number and percentage of missed blood pressure or body weight measurements. - Treatment adherence: pill count and medication concentration in urine samples. Secondary trial endpoints: The secondary trial endpoints are: - Change from baseline in UACR from start to end of treatment with empagliflozin. - Change from baseline in systolic blood pressure, body weight, eGFR, and fasting plasma glucose from start to end of treatment with empagliflozin. - (Additive) treatment effects on UACR, systolic blood pressure, body weight, eGFR, and fasting plasma glucose from start to end of treatment after the addition or substitution with finerenone. Trial design: This is a single-centre, prospective, open-label, decentralised, crossover pilot study where participants are participating for 10 weeks. Trial population: Adult participants with type 2 diabetes, UACR >4.5 mg/mmol (>40 mg/g) and ≤300 mg/mmol (≤2655 mg/g), and eGFR ≥25 mL/min/1.73m2 who are on stable treatment with an angiotensin-converting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB), unless not tolerated. The investigators aim to recruit 10 participants who are receiving care in primary or secondary healthcare settings. Interventions: Eligible participants will be assigned to a 3-week treatment period with the SGLT2 inhibitor empagliflozin 10 mg/day, in accordance with guidelines. After 2 weeks, albuminuria levels will be assessed to determine the individual albuminuria response. Depending on the response (decrease or increase), participants will be allocated to one of three treatment regimens following the 3-week empagliflozin treatment period: A. Albuminuria reduction >30% and the remaining albuminuria level is <30 mg/g: continue empagliflozin 10 mg/day for an additional four weeks. B. Albuminuria reduction >30% or >0 and ≤30%, and the remaining albuminuria level is >30 mg/g: continue empagliflozin 10 mg/day for an additional four weeks and intensify treatment by adding finerenone 10 or 20 mg/day for four weeks (dosage depends on eGFR levels). C. No albuminuria reduction or increase: discontinue empagliflozin and switch to finerenone 10 or 20 mg/day for four weeks (dosage depends on eGFR levels). Ethical considerations relating to the clinical trial including the expected benefit to the individual participants or group of patients represented by the trial participants as well as the nature and extent of burden and risks: Both medicinal products are indicated for the treatment of patients with type 2 diabetes supported by multiple large-scale international clinical trials. Empagliflozin is currently marketed and recommended for adult patients with CKD, both with and without diabetes. It can be prescribed to individuals with an eGFR as low as 20 mL/min/1.73m2. The efficacy and safety of empagliflozin have been demonstrated in numerous parallel randomised controlled trials involving over 25,000 patients with type 2 diabetes. The most frequently reported adverse reaction when used in conjunction with sulfonylureas or insulin was hypoglycaemia. Other commonly reported adverse reactions included volume depletion, urinary tract infections, genital infections, thirst, constipation, (generalised) pruritus, rash, increased urination, and elevated serum lipids. Finerenone is currently marketed and recommended for use in adult patients with type 2 diabetes and stage 3 or 4 CKD, as indicated by an eGFR <60 mL/min/1.73m2 and a UACR >3 mg/mmol. The efficacy and safety of finerenone have been established through multiple parallel randomised controlled trials involving more than 10,000 patients with CKD and type 2 diabetes. The most frequently reported adverse reactions during treatment with finerenone was hyperkalaemia (14.0%). Other common adverse reactions included hyponatremia, hyperuricemia, hypotension, pruritus, and decreased GFR. Due to the modest increase in risk of hyperkalaemia with finerenone, the investigators will include only patients with serum potassium <5.0 mmol/L in this study. Guidelines from professional nephrology and cardiology associations now recommend the use of SGLT2 inhibitors and finerenone for all patients with type 2 diabetes and CKD. Participants who exhibit a favourable response to empagliflozin and/or finerenone and whose characteristics align with the criteria for clinical use can consult their treating physician to evaluate the ongoing use of empagliflozin and/or finerenone and to determine if additional laboratory assessments are necessary. Participating patients will be given free study medications and an opportunity to identify the optimal personalised regimen evaluated by objective assessment under the supervision of the study team. Participants visit the study site on three occasions: a screening visit, baseline visit, and an end-of-study visit. This trial will adopt a decentralised approach in which participants will measure and collect study variables at home, including biochemical urine and capillary blood data, blood pressure, and body weight. This will minimize patient travel, study site visits, and facilitate clinical trial participation. Instructions for remote data collection are provided during the second study visit, and data collection occurs on scheduled days. Biochemical urine data are obtained from first-morning void urine samples using the PeeSpot device. Capillary blood samples are collected using a BD Microtainer Contact-Activated lancet and Hem-Col tubes. Participants send their urine and capillary blood samples to the laboratory by mail. To familiarize participants with blood collection procedures, they perform a capillary blood sample collection at the study site during the second visit under the supervision of a trained lab technician. Additionally, a venous blood sample is drawn during the second study visit to enable comparison of clinical chemistry assessments between capillary and venous blood samples. Blood pressure and body weight measurements are performed using validated smart devices. Blood pressure and body weight measurements will be automatically stored in the corresponding mobile application. The overall study duration is expected to be 10 weeks. The expected time commitment for participants is approximately 25 hours, including at-home measurements. ;
