Empagliflozin Versus Linagliptin in Renal Ransplant Recipients With Diabetes Mellitus (EmLina Renal)

Effect of Empagliflozin Versus Linagliptin on Glycemic Outcomes, Renal Outcomes and Body Composition in Renal Transplant Recipients With Diabetes Mellitus: Randomized Controlled Trial

This EmLina Renal trial is an investigator initiated, single-center, prospective, open-label, randomized clinical study to examine the safety and effect of empagliflozin 25 mg once a day vs. linagliptin 5 mg once a day for 12 months on glycemic outcomes, renal outcomes and body composition in renal transplant recipients with diabetes mellitus. Glycemic variables will include fasting glucose and glycated hemoglobin (HbA1c). Renal outcomes will include change in eGFR, spot urine albumin-creatinine ratio (UACR) and spot urine protein-creatinine ratio (UPCR). Body composition variables will include total fat mass, fat percentage, total lean mass, and bone mineral content as measured by dual-energy X-ray absorptiometry (DEXA). Body composition will also be measured by BIA. The study will be conducted according to the CONSORT guidelines. The patient population for the trial will be derived from Medanta-The Medicity Hospital endocrine and nephrology out-patient clinic. The study will be conducted in Medanta-The Medicity Hospital, Gurugram, Haryana, which is a tertiary care center in North India. Patients deemed eligible will be screened for the trial

Detailed Description

This EmLina Renal trial is an investigator initiated, single-center, prospective, open-label, randomized clinical study to examine the safety and effect of empagliflozin 25 mg once a day vs. linagliptin 5 mg once a day for 12 months on glycemic outcomes, renal outcomes and body composition in renal transplant recipients with diabetes mellitus. Glycemic variables will include fasting glucose and glycated hemoglobin (HbA1c). Renal outcomes will include change in eGFR, spot urine albumin-creatinine ratio (UACR) and spot urine protein-creatinine ratio (UPCR). Body composition variables will include total fat mass, fat percentage, total lean mass, and bone mineral content as measured by dual-energy X-ray absorptiometry (DEXA). Body composition will also be measured by BIA. The study will be conducted according to the CONSORT guidelines. The patient population for the trial will be derived from Medanta-The Medicity Hospital endocrine and nephrology out-patient clinic. The study will be conducted in Medanta-The Medicity Hospital, Gurugram, Haryana, which is a tertiary care center in North India. Patients deemed eligible will be screened for the trial. The study will be registered at clinicaltrials.gov. The clinical trial protocol will be presented for approval to the institutional ethics review board. Informed written consent will be obtained from all the participants before enrolment into the study.

Baseline assessment at screening All patients will undergo a baseline assessment before randomization, including detailed medical history, physical examination including anthropometry and biochemical evaluation.

Randomization A research assistant will randomize the patients into either Empa group or Lina group in a 1:1 ratio using computer-generated numbers.

Study visits After careful assessment at the baseline visit, patients meeting all inclusion and exclusion criteria will be randomized to receive empagliflozin 25 mg once a day tablet for 12 months. The Lina group will receive linagliptin 5 mg daily for 12 months. Both groups will receive metformin and/or insulin and/or sulfonylureas for the management of diabetes. The study design included 3 in-person visits (baseline and months 6 and 12) and 2 telephonic visits (at months 3 and 9).

Primary and secondary outcomes The primary outcome measure is the change in renal outcomes (changes from baseline in estimated glomerular filtration rate (eGFR), spot urine albumin- creatinine ratio and spot urine protein-creatinine ratio). The secondary outcome measures are changes in total fat content, fat percentage, lean mass and bone mineral content from baseline (as measured by DEXA); changes in total fat content, fat percentage, lean mass and bone mineral content from baseline (as measured by BIA), and glycemic variables (fasting glucose and HbA1c at baseline, 6 and 12 months). The safety profile will be documented carefully at all in-person and telephonic visits.

Statistical analysis Plan The analysis will include profiling of patients on different demographic, clinical and laboratory parameters etc. Quantitative data will be presented in terms of means and standard deviation and qualitative/categorical data will be presented as absolute numbers and proportions. To compare between the two groups, the Chi-squared test or Fisher's exact test will be used for categorical variables, and the independent samples t test or Wilcoxon-Mann-Whitney U test will be used for the differences between continuous variables. Pearson correlation coefficient will be used to evaluate correlations between variables. Additional analyses of primary and secondary outcomes within treatment groups will be performed by using two-tailed independent sample t tests, paired t tests, or non-parametric tests, when indicated. P-value < 0.05 is considered statistically significant. SPSS software will be used for analysis.

Patient confidentiality Precautions will be taken to ensure confidentiality. Data collection forms will not reveal the name of patients included in study. All the participants will be covered by insurance to cover the cost of any untoward effect directly resulting from enrolment in the study.

Description

Inclusion Criteria:

1. A man or woman, 30 years of age or above with the diagnosis of diabetes mellitus (pre-transplantation type 2 diabetes or post-transplantation diabetes mellitus) and after at least 3 months of renal transplantation.
2. Patients must have stable renal function (less than 20% deviation in serum creatinine in last one month: eGFR >30 ml/min/1.73 m2)
3. Patients must be on a stable immunotherapy for last one month.
4. Subjects must be medically stable on the basis of medical history, physical examination and laboratory investigations.
