The goal of this open pilot is to practice using an intervention and surveys before a larger pilot stepped wedge clinical trial. The intervention the researchers plan to use is Chronic Kidney Disease (CKD) Topics, and it is a structured clinical agenda-setting intervention (SAS), or a customized list of discussion topics. The people the researchers are practicing using the SAS with have advanced CKD (stages 4-5), and many of them live in rural areas. The researchers will practice administering CKD Topics, along with survey questions. By doing the open pilot, the researchers will learn if they need to modify the steps they plan to take in the larger trial. The main questions the researchers aim to answer are: * Do the steps for identifying eligible participants work? * Do the steps for administering CKD Topics work? * Do the steps to administer survey questions work?

The goal of this crossover clinical trial is to explore the effects of red meat intake on serum and fractional urinary excretion of uremic toxins including trimethylamine N-oxide in people with chronic kidney disease.

The goal of this clinical trial is to learn if a tool with a list of discussion topics, called a structured clinical visit agenda-setting intervention (SAS), works for people with advanced chronic kidney disease (CKD) who receive care at a clinic that serves people who live in rural areas. The SAS is called CKD Topics. The researchers will compare the SAS intervention to usual care (the way clinicians usually practice) to see how well it works for people with advanced CKD. This is a special type of clinical trial called a stepped wedge randomized clinical trial (RCT). In this type of trial, every participant will get to experience both usual care and CKD Topics, but for different amounts of time. The researchers will learn if doing a clinical trial of CKD Topics is possible (feasible) and get information about how well CKD Topics helps people with advanced CKD shape visit discussions (self-advocacy) in their appointments with their clinicians. The information the researchers collect in this trial will help design a future trial with more participants. The main questions the researchers aim to answer are: * Is it possible to conduct this type of study of a SAS intervention? i.e. feasibility * Does the SAS intervention help people with advanced CKD shape discussions (self-advocacy) with their clinicians? If so, how much? i.e. preliminary efficacy

The goal of this clinical trial is to learn about the safety (good or bad) of giving two AION-301 intravenous (IV) infusions, in adults with Stage 3 Chronic Kidney Disease (CKD). It will also help to learn if AION-301 reduces the symptoms of CKD and/or progression. The main questions it aims to answer are: * Do participants have medical problems (adverse events) after receiving two infusions of AION-301? * Do participants feel better (have reduced and/or delayed CKD symptoms)? * To learn about how AION-301 works in participants with CKD? Researchers will compare AION-301 to a placebo (a look-alike substance that contains no drug) to see if AION-301 works to treat Stage 3 CKD. Participants will: * Receive two infusions of AION-301 or placebo on two separate days (Day 0 and Day 4). * Receive oral vitamins at the clinic and to take at home for 90 days. * Visit the clinic for a minimum of 9 times, over 6 months for checkups and tests, but could be up to 12 times, over 24 months for checkups and tests.

In this pilot clinical trial, the investigators will recruit and randomize 120 patients with diabetes mellitus and chronic kidney disease (CKD/DM) stages 3 to 5 to a patient-centered and flexible Plant-Focused Nutrition in Diabetes (PLAFOND) diet with \>2/3 plant-based sources, which will be compared with a standard-of-care CKD diet, which is usually a low-potassium and low-salt diet, over a 6-month period. Through this study, the investigators will determine whether the plant-focused diet intervention is feasible for patient adherence, whether this diet is safe by avoiding malnutrition, frailty, and high potassium or glucose blood levels, and whether patient reported outcomes are favorably impacted.

This trial tests a special stem cell transplant followed by a kidney transplant in patients who need a new kidney. The goal is to prevent kidney rejection without lifelong medication by preparing the immune system to accept the new kidney.

The study objective is to characterize the pharmacokinetics (PK), pharmacodynamics, and surrogate measures of efficacy for canagliflozin in patients with advanced CKD, including those receiving HD. As the CV and renoprotective effects of SGLT-2 inhibitors appear to be independent of glycemic control, the investigators hypothesize that canagliflozin will reduce albuminuria in patients with advanced CKD in the same manner as observed in patients with higher eGFR. The investigators also hypothesize that the 300 mg dose will be equally safe as the 100 mg dose but will have greater efficacy, given data which suggests efficacy correlates with drug exposure in patients without CKD. Given its negligible renal elimination, the investigators hypothesize that exposure to canagliflozin 100 mg at steady state will not exceed the standard bioequivalence boundary of 80-125% in patients receiving HD, compared with published estimates with the 300 mg dose at steady state in individuals with preserved kidney function.
