About this study

Official title: Multi-Center, Prospective, Randomized Trial To Demonstrate Improved Metabolic Control of PEN VS Dianeal Only in Diabetic CAPD and APD Patients - The Impendia Trial

Primary Objective: To demonstrate that use of glucose sparing prescriptions (PEN vs Dianeal only) in diabetic (Type 1 and Type 2) Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD)patients leads to improved metabolic control as measured by the magnitude of change from the baseline value in the HbA1c levels.

Secondary Objectives: To demonstrate that use of glucose-sparing PD solutions (PEN vs Dianeal only) in diabetic (Type 1 and Type 2) CAPD and APD patients leads to lower glycemic-control medication requirements, decreased incidence of severe hypoglycemic events requiring medical intervention, improved metabolic control, nutritional status, and Quality of Life. In a subgroup of patients, the impact of glucose-sparing PD solutions (PEN vs Dianeal only) on abdominal fat and left ventricular (LV) structure and function will be assessed.

Read the detailed description

The data represented in this module is a pooled analysis of the following 3 studies: NCT00567489 (protocol ID 31998), NCT00567398 (protocol ID 34202), NCT01219959 (protocol ID51067). Given that the glucose content of the PD solutions is similar, the pooling of the results were considered a valid method to answer the underlying research questions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From the Baseline Value in HbA1c at Month 3 and 6

    HbA1c is a specific glycohemoglobin, and adduct of glucose attached to the beta-chain terminal valine residue. Measured using a Tina-quant immunological assay suitable for samples from end stage renal disease (ESRD) patients and with icodextrin metabolites or equivalent. Statistical analysis includes estimates of Least Squares (LS) comparing differences between treatment groups by visit and p-value using analysis of covariance (ANOVA) testing that the differences=0.

    Measured: Baseline, Month 3, Month 6 (End of Study)

Secondary outcomes (21)
  1. Change From Baseline in Glycemic Control Medication Usage at Month 3 and 6

    This data used diabetic prescription drug information from insulin and oral glycemic control concomitant medications reported. Glycemic control medications classes allowed were limited to insulin, sulfonylureas, and thiazolidinediones. Subjects were provided with a paper diary on which they recorded doses of all glycemic control medications taken for 1 day prior to the Screening visit and for 8 days prior to the study visits at Month 3 and Month 6. Statistical analysis includes estimates of Least Squares (LS) comparing differences between treatment groups by visit and p-value using analysis of covariance (ANOVA) testing that the differences=0.

  17. Change From Baseline in QOL Based on the Diabetes Symptom Checklist (DSC) at Month 3 and 6

    The Diabetes Symptoms Checklist was designed to assess the presence and perceived burden of diabetes-related symptoms. Respondents were to consider troublesomeness of 34 symptoms on a 5-point scale ranging from 5="extremely" to 1="not at all." For symptoms/side-effects not experienced, the item was scored as 0. Symptoms were grouped into the following subscales: psychological fatigue, psychological cognitive, neurology pain, neurology sensory, cardiology, ophthalmology, hypoglycemia, hyperglycemia. Subscale scores were calculated as the sum of the given subscale divided by the total number of items in the scale. Total score was computed from the sum of the 8 subscales and ranged from 0 to 40. Higher scores indicate greater symptom burden. Statistical analysis includes estimates of Least Squares (LS) comparing differences between treatment groups by visit and p-value using analysis of covariance (ANOVA) testing that the differences=0.
