The Effect of a Renal Specific Oral Nutritional Supplement on Nutritional Status

The Effect of a Renal Specific Oral Nutritional Supplement on Nutritional Status and Other Outcomes

The study objective is to evaluate if a renal specific oral nutrition supplement (ONS) aids in maintaining nutritional status.

Study Overview

• Status: Completed
• Conditions: Chronic Kidney Disease
• Intervention / Treatment: Other: Oral Nutritional Supplement (ONS)

Detailed Description

This study is an unblinded, prospective, multicenter, single arm study in Taiwan. Eligible subjects (see inclusion and exclusion criteria in Section 5.2) will receive standard of care (which includes dietary counseling) and ONS supplementation (1-2 servings/day depending on subject's needs) for 24 weeks (6 months). A follow up visit (phone call/medical chart review) will occur 12 months after the study intervention has ended to collect mortality data, to determine whether or not dialysis was initiated, and if ONS use continued.

Subjects will be informed of the study results when available. Subjects may continue use of the commercially available study product if it is recommended by their nephrologist, primary care physician, dietitian, or if the subject chooses.

For this study enrollment is defined as when the subject is stratified and begins to consume the study product (Study Visit 1, Month 0).

The target population described above may be stratified into the following groups (n=18 evaluable/group):

1. Male CKD Stage 3b-5 without T2DM
2. Male CKD Stage 3b-5 with T2DM
3. Female CKD Stage 3b-5 without T2DM
4. Female CKD Stage 3b-5 with T2DM

In addition, for those subjects enrolled, retrospective data (previous 6 to 12 months) identical to the study variables will be collected. Retrospective data collection will focus on the following measures, however, all data points are not expected to be available:

• Serum albumin
• SGA
• Compliance to protein intake guidelines
• Compliance to energy intake guidelines
• Hand grip strength
• Anthropometrics (weight, height, BMI)
• Quality of Life (WHOQOL-BREF Taiwan Version)
• eGFR (whichever equation is used as standard of care)
• Serum creatinine
• Proteinuria (retrospective - if available on medical records)
• BUN
• Body composition data from BIA (especially fat mass and muscle mass, units or exact terminology will be model specific)
• C reactive protein (CRP)
• Blood chemistries,

• Study Type: Interventional
• Enrollment (Actual): 53
• Phase: Not Applicable

2. Subject is >18 years of age.
3. Subject has been diagnosed with Chronic Kidney Disease (CKD) and is classified as being between Stages 3b to 5.
4. Subject has an eGFR 45 and 10 ml/min/1.73m2 at screening.
5. Subject is a male or non-pregnant female at least six weeks postpartum and non-lactating.

6. Subject with CKD is either:

   • not diagnosed with Type 2 Diabetes Mellitus (T2DM) OR
   • diagnosed with T2DM and had no changes in glycemic medication (dose or type) for at least 2 months prior to screening
7. Subject has a serum albumin 3.0 g/dl at screening.
8. Subject has a BMI 30 kg/m2.
9. If diagnosed with T2DM, subject has A1c level 9.0% at screening.
10. Subject is not scheduled or expected to receive dialysis in the next 18 months.
11. Subject's life expectancy is 18 months determined by the study physician.
12. Subject is willing to follow the protocol as described.

13. With regard to ONS use the subject must qualify as one of the following:

    1. be naïve to ONS
    2. if the subject is already prescribed another ONS that is not the study product, and they have consumed 8 servings over the last 28 days prior to screening, they will undergo a washout period (3 weeks)
    3. if the subject is already prescribed the study product, and they have consumed ≤ 8 servings over the last 28 days prior to screening, or have poor daily compliance (< 75%), they will undergo a washout period (3 weeks)
    4. if the subject is already prescribed the study product, and they have been consuming 1-2 servings daily, with >75% compliance, for < 3 months, they do not require a washout period, and can be retrospectively included in the study protocol (provided proper records can be obtained)
