Status Recruiting

Clinical Trial Summary

The aim of the study is to assess the improvement of health in patients affected by CKD when they are exposed to non-pharmacological treatment strategies as nutritional program (NP), physical activity program (PA) and mindfulness program (MP), when they are conveyed to the patient by means of digital technologies or not. In the present study, non-pharmacological interventions conveyed by a digital technology (investigational arm) will be compared to a standard, paper-based approach (control arm).

Clinical Trial Description

KidneYou is a medical device designed to deliver digital therapy (DT) to patients. The DT, as part of Digital Health, utilizes high quality digital technologies to stimulate lifestyle changes in patients. KidneYou has been set up to improve the commitment of patients in following therapeutic directives (i.e. nutritional programs, daily/weekly physical activities) to manage their chronic diseases like CKD. Moreover, KidneYou can improve patient's awareness about his/her disease (mindfulness) so as to increase the individual human ability to be fully present at the ongoing disease's condition and react to it in active and positive manner.

The aim of this study is to determine whether the medical device KidneYou, randomly assigned to CKD patients (G3b/G4 categories; A1/A2 categories), can improve the CKD-related patient's health conditions by positive changes in the subject's lifestyle (i.e., healthy eating, physical activity participation) and by means of cumulative stress reduction (i.e., mindfulness program) originating from the underlying chronic disease and from diagnosis and treatment interventions necessary to manage it. Some lifestyle programs (i.e., nutrition and physical exercises) will be delivered to both randomized groups by different modalities (i.e. with/without KidneYou), while other programs (i.e., mindfulness) will only be accessible to KidneYou users, requiring a technology support for the multimedia content to be self-administered daily by the App. This innovative method avoids a daily face-to-face intervention administered by healthcare professionals for mental health treatments. Broadly speaking, it is expected that KidneYou may improve a patient's adherence to clinical advices and consequently patient's health condition in users compared to non-users. The enrolled subjects will be randomly assigned to one of the two treatment arms according to a parallel-group design. Subjects included in Group A (intervention group) will be provided with KidneYou, while patients in Group B (non-equivalent group) will be used as control. The study will enrol 210 subjects, both genders, aged ≥18 years, to obtain 190 overall valuable subjects (95 each group). The recruitment period will last 12 months.

For each patient the treatment will last 3 consecutive months (12 weeks) during which lifestyle changes will be implemented with/without KidneYou. At the end of this period the lifestyle program will be terminated, followed by a follow-up visit after 1 further month (16 weeks). The follow-up visit will be used to observe the sustained effects on patient's health 30 days after termination of the change lifestyle programs administered to patients with and without KidneYou.

At the beginning of the study, patients will be evaluated for their stress level by means of the Perceived Stress Scale (PSS) by Cohen (Cohen, 1983). Specifically, it will be used the Italian translation of PSS-10, which is a 10-item questionnaire designed to tap how unpredictable, uncontrollable, and overloaded respondents find their lives. To customize the stress measurement to the population age range expected in this study, according to Norm Table for the PSS 10-item inventory, a cut-off of 12 points was chosen. Therefore, all subjects with a score >12 in the PSS questionnaire delivered at the first study visit (V0), will be considered to have a higher stress level above normal and to have one of the major inclusion criteria.

Each subject will undergo 4 (four) visits and will be examined according to the following schedule:

• V0 - Baseline

• V1 - 6 weeks after baseline (Day 42±2)

• V2 - 12 weeks after baseline (Day 84±2. End of lifestyle program administration)

• V3 - 4 weeks after V2 (Day 112±4. Follow-up visit and End of Study [EOS] visit)

Benefit/Risk Assessment Benefits for patients resulting from study implementation are the simultaneous application of the three non-pharmacological programs for improving the health of CKD patients. The expected results are that the simultaneous use of the three programs will allow greater improvements than those achieved so far with the separate use of programs. Instead of the experimental evidence published so far, the present study intends to measure the objective benefits rather than the perceived ones by CKD patients. For this, the composite primary objective/endpoint consists of easily measurable objective markers.

Improvements are expected in both treatment groups, as food and physical programs will also be implemented in the control (KidneYou non-users) group. However, in the investigational group (KidneYou users) it is assumed to achieve higher benefits, thanks to the possibility to offer, by means of the App software, the third psychological program (mindfulness) consisting of multimedia contents. The higher expected benefits in the investigational group are justified by the greater attractiveness of the App compared to paper diary in the control group, with a consequent increase in compliance and effectiveness in KidneYou users.

Possible risks that can be anticipated in this specific study population may be related to clinical events emerging from adherence to at least one of the three non-pharmacological programs, such as hypoglycemia, nausea, vomiting, gastrointestinal discomfort, physical accidents during exercises, hypertensive crises, obsessive feeling about exercise and food intake, anxiety/guilt when not reaching assigned exercise or food intake goals, interferences with subject's daily activities and/or social life, neuroses about individual body image or any other adverse experience.

Primary Endpoints

• To evaluate the achievement of a mean reduction of at least 10% of azoturia (g/24h) in Chronic Kidney Disease (CKD) KidneYou users exposed to a 3-month Nutritional Program (NP) compared to CKD KidneYou non-users exposed to the same 3-month NP.

OR

• To evaluate the achievement of a mean increase of at least 15% of distance (meters in the 6-MWT) in CKD KidneYou users exposed to a 3-month PA Program compared to CKD KidneYou non-users exposed to the same 3-month PA Program.

OR

• To evaluate the achievement of a mean decrease of at least 10% of perceived stress (according to the Perceived Stress Scale [PSS] of Cohen) in CKD KidneYou users exposed to a 3-month Mindfulness Program (MP) compared to CKD KidneYou nonusers and non-exposed to the same MP.

Safety Endpoint To assess the rate of adverse events, adverse device effects, abnormality of laboratory

Statistical Hypotheses This study is designed to test the null hypothesis that the percentage 'success' (intended as primary endpoint achievement) in KidneYou non-users is equal to the percentage 'success' in KidneYou users. The alternative hypothesis is that the percentage 'success' in KidneYou nonusers is different from the percentage 'success' in KidneYou users.

Sample Size Determination The sample size is estimated to provide statistical power for the primary endpoint. The sample size calculation is based on the combination of expected proportion of success in the control group and expected delta (Δ) of success in the experimental group.

With a significance level α equal to 0.05 and a power equal to 80%, a sample size of 190 subjects (95 per group) is required to detect as significant, if any, a success delta in favor of the experimental group equal to 20% (under the hypothesis of success rate of 40% in the control group and success rate of 60% in the experimental group).
