About this study
The purpose of this randomized clinical trial is to evaluate the efficacy of 3 different technology-supported approaches to engaging 300 individuals with diabetes and concurrent chronic kidney disease in weight loss, dietary sodium restriction, and dietary restriction of inorganic phosphates when compared to usual care. Participants will be randomized to 1 of 4 groups, Usual Care (UC), Social Cognitive Theory-based Group Counseling (SCT), Mobile self-monitoring with tailored feedback and counseling (MONITORING), or a combination of SCT plus MONITORING conditions (COMBINED). Investigators will evaluate the intervention arms primarily in terms of weight reduction, urinary sodium excretion, and serum phosphorus and, secondarily in terms of physical activity, blood pressure, fasting lipids, medication requirements, and pulse wave velocity. Measurements will occur at baseline, 6, and 12 months. The statistical modeling of the baseline, 6 mos and 12 mos outcome variables will be based on logistic generalized linear mixed models (for binary outcomes) linear mixed models (for continuous outcomes), and random effects multinomial models (for outcomes with more than 2 levels, such as changes in medication management). In separate analyses of the intervention arm only, investigators will model self-monitoring adherence and examine possible associations between self-monitoring adherence and outcomes. The mediating effect of self-efficacy on the primary outcomes will be evaluated using structural equation models.

II. CHARACTERISTICS OF THE RESEARCH POPULATION
- Number of subjects. Investigators will recruit 300 participants to the study. Investigators will focus our study on those with diabetic CKD as this form of the disease progresses more rapidly than other forms of CKD. Focusing on diabetic CKD also allows us to expand logically upon Look AHEAD, and build upon our work in T2DM patients with the ENHANCE study. Investigators will recruit participants from 3 clinical sites in New York City: Nephrology Family Group Practice at NYU Langone Medical Center (NYULMC), the Bellevue Hospital Diabetes Clinic, and New York Harbor VA. Preliminary data from these 3 practice settings indicate that investigators will have access to 4,292 potentially eligible patients from which investigators must recruit only 7.0% to enroll 300. Our prior studies suggest that investigators will retain 80% resulting in a final sample of 240. Investigators are projecting 64 participant measurement visits in Year 1; 248 in Year 2; 288 in Year 3; 244 in Year 4; and 56 in Year 5.
Unless otherwise noted, measurements occur at baseline, 6, and 12 mos. Data are collected with visits to NYU Clinical and Translational Resource Center (CTRC). Information to be obtained from participants at each visit includes height and weight, serum and urine samples; blood pressure; investigator administered instruments (sociodemographics, comorbid conditions, Mini Mental Status Exam, and self-efficacy instruments), medication inventories, and Pulse Wave Velocity. Eight blood tests will be performed: cystatin-C, lipids, phosphorus, calcium, PTH or parathyroid hormone, vitamin D, pre-albumin and albumin. These tests are estimated to require, in total, approximately 45 mls (of blood.
One week before their scheduled measurement visit, a 24-hour urine specimen container and instructions for collection are mailed to the participant. Participants are contacted 2 days prior to their appointment to remind them of their measurement visit, collect their urine, fast, and abstain from caffeine for 12 hours prior to their appointment. Laboratory tests are collected, spun, refrigerated, batched and sent for processing in the CLIA-certified NYU CTSI Translational Research Laboratories by personnel blinded to group assignment. The PWV of the brachial-ankle (baPWV) and carotid-femoral (cfPWV) will be collected by trained research associates at the CTRC.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Social Cognitive TheoryBehavioural
Also called SCT
focuses on the role played by self-referent thought in the maintenance of behavior change. Self- efficacy (e.g., the participant's confidence in their ability to engage in healthier behavior) is derived from four major sources of information: mastery experiences, social modeling, verbal persuasion, and physiological states
MonitoringOther
Also called Technology-based self-monitoring
Technology-based self-monitoring reduces information processing demands by making relevant nutritional information readily available. Technology-based self-monitoring also can be used by interventionists to reduce information processing burden by using it for targeted counseling. For example, simultaneous consideration of all pertinent dietary recommendations would likely be overwhelming for an obese person with diabetes and CKD. By using an electronic log accessible to the interventionist, such a person could initially focus on calorie restrictions, with the interventionist stepping-in when problematic behaviors become evident.
| Study group | Role | What they receive |
|---|---|---|
| Usual Care (UC) | No intervention | Participants randomized to UC will receive baseline advice about the value of losing weight, becoming more physically active, and limiting intake of sodium and inorganic phosphates followed by 12 mos of UC. We have elected not to use a control group in which we provide equivalent attention to both study arms. Behaviors are difficult to change and there is no reason to believe that simply giving participants attention would create behavioral changes sufficient to result in weight loss, reduce sodium excretion, or reduce serum phosphorus. Numerous weight loss studies, including Look AHEAD, have used attention control groups that did not demonstrate weight loss. |
| Social Cognitive Theory (SCT) | Active comparator | Participants will be exposed to a group behavioral intervention that is based on SCT, which focuses on the role played by self-referent thought in the maintenance of behavior change. Self- efficacy is derived from four major sources of information: mastery experiences, social modeling, verbal persuasion, and physiological states. Mastery experiences will include emphasizing past successes; setting incremental, easily achievable goals; identifying modifiable barriers to healthy behavior; receiving positive feedback on goal achievement; and practicing problem solving skills around barriers to adherence. Receives: Behavioral: Social Cognitive Theory |
| Monitoring | Active comparator | Participants will be taught how to use a lifestyle self-monitoring program to reduce information processing requirements, make readily available the information required to make good self-management decisions, deliver automated, real-time feedback about achievement of behavioral goals, and permit individualized guidance from an interventionist who uses the MyNetDiary® electronic log to provide targeted education and advice. The Monitoring intervention reduces information processing demands by making relevant nutritional information readily available. Technology-based self-monitoring also can be used by interventionists to reduce information processing burden by using it for targeted counseling Receives: Other: Monitoring |
| Combined | Active comparator | Participants randomized to COMBINED will receive all aspects of the SCT and MONITORING intervention conditions. Social Cognitive Theory based behavioral intervention in complex patients is strengthened when technology is used to manage information complexity, and weakened in its absence. The Monitoring intervention reduces information processing demands by making relevant nutritional information readily available. Technology-based self-monitoring also can be used by interventionists to reduce information processing burden by using it for targeted counseling Receives: Behavioral: Social Cognitive Theory; Other: Monitoring |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this randomized clinical trial is to evaluate the efficacy of 3 different technology-supported approaches to engaging 300 individuals with diabetes and concurrent chronic kidney disease in weight loss, dietary sodium restriction, and dietary restriction of inorganic phosphates when compared to usual care.

Investigators will evaluate the intervention arms primarily in terms of weight reduction, urinary sodium excretion, and serum phosphorus and, secondarily in terms of physical activity, blood pressure, fasting lipids, medication requirements, and pulse wave velocity. Measurements will occur at baseline, 6, and 12 months. The statistical modeling of the baseline, 6 mos and 12 mos outcome variables will be based on logistic generalized linear mixed models (for binary outcomes) linear mixed models (for continuous outcomes), and random effects multinomial models (for outcomes with more than 2 levels, such as changes in medication management). In separate analyses of the intervention arm only, investigators will model self-monitoring adherence and examine possible associations between self-monitoring adherence and outcomes. The mediating effect of self-efficacy on the primary outcomes will be evaluated using structural equation models.

Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Weight in kgs will be obtained using a single, calibrated scale (time frame: Change from baseline in weight at 6 months). The study lists 6 primary outcomes in all. 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 NCT02276742, which also lists 4 linked publications.
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 14 Jul 2020.
