Brief summary

The goal of this clinical trial is to learn if starting four kidney disease medicines quickly and together (a rapid treatment approach) is safe and works well in people with type 2 diabetes and chronic kidney disease. The main questions it aims to answer are: * Is it safe to start these medicines over a short period of time? * How often do kidney function changes or high potassium levels occur? * Does this approach lower protein in the urine (a sign of kidney damage)? * How many participants are able to stay on all four medicines over 6 months? Researchers will compare this approach to usual care, where medicines are started one at a time over several months. Participants will: Be assigned by chance to either this approach or usual care Start up to four approved kidney medicines over about 8 weeks (rapid treatment approach) or follow standard care Have regular clinic visits and lab tests to check kidney function and potassium levels Be followed for about 6 months

Detailed description

This study is a pilot, open-label, randomized clinical trial designed to evaluate the feasibility, safety, and effectiveness of rapidly starting multiple guideline-recommended therapies in people with type 2 diabetes and chronic kidney disease. In current clinical practice, these medicines are usually started one at a time over many months. This step-by-step approach may delay potential benefits and leave people at continued risk of kidney disease progression and cardiovascular complications. This study will test a different approach, where these therapies are started in a structured and closely monitored way over a short period of time. Participants will be randomly assigned to either a rapid initiation strategy or usual care. In the rapid group, up to four approved therapies will be started and adjusted over approximately 8 weeks using a structured treatment plan. In the usual care group, treatment will follow standard clinical practice, where medications are introduced gradually at the discretion of the treating clinician. Participants in both groups will be followed for 6 months. During this time, they will have regular clinic visits and laboratory testing to monitor kidney function, potassium levels, and overall treatment tolerance. This pilot study will provide important information on whether this rapid treatment approach can be safely implemented in real-world clinical settings and whether participants are able to start and continue multiple therapies within a short time frame.

Number of participants who achieve >30% reduction in urine albumin-to-creatinine ratio6 monthsNumber of participants achieving \>30% reduction in urine albumin-to-creatinine ratio
Change in Kidney Disease Quality of Life-36 score6 monthsChange from baseline in Kidney Disease Quality of Life-36 (KDQOL-36) score. Scores range from 0 to 100, with higher scores indicating better quality of life.
Change in Patient-Reported Outcomes Measurement Information System score6 monthsChange from baseline in Patient-Reported Outcomes Measurement Information System (PROMIS) score. PROMIS includes seven domains: Physical Function, Anxiety, Depression, Fatigue, Sleep Disturbance, Ability to Participate in Social Roles and Activities, and Pain Interference. Each domain includes 4 items scored from 1 to 5, with raw domain scores ranging from 4 to 20, and domain scores are converted to standardized T-scores with a mean of 50 and standard deviation of 10. A separate Pain Intensity item is rated on a 0 to 10 scale, where 0 indicates no pain and 10 indicates worst imaginable pain. For Physical Function and Ability to Participate in Social Roles and Activities, higher scores indicate better health. For Anxiety, Depression, Fatigue, Sleep Disturbance, Pain Interference, and Pain Intensity, higher scores indicate greater symptom burden or worse health status.

TBQ is composed of 13 items rated on a Likert scale ranging from 0 (not a problem) to 10 (big problem) and assesses the burden associated with taking medicine, self-monitoring, laboratory tests, doctor visits, need for organization, administrative tasks, following advice on diet and physical activity, and social impact of the treatment. TBQ item scores can be summed into a global score, ranging from 0 to 130. Higher scores indicating greater treatment burden.
Change in Living with Medicines Questionnaire version 3 score6 monthsChange from baseline in Living with Medicines Questionnaire version 3 (LMQ-3) score. LMQ-3 consists of 41 items scored on a 5-point Likert scale. Total scores range from 41 to 205, with higher scores indicating greater treatment burden.
