Study Details
Study Description
Brief Summary
This D-LIFT (Effect of dulaglutide on Liver Fat) trial is an investigator initiated, prospective, open label, randomized clinical study to examine the effect of dulaglutide 0.75 mg subcutaneously weekly for 4 weeks, followed by 1.5 mg weekly for 20 weeks when included in the standard treatment for type 2 diabetes vs. standard treatment for type 2 diabetes (minus dulaglutide) in patients with type 2 diabetes and NAFLD. Hepatic steatosis (intracellular fat accumulation in hepatocytes) will be measured by MRI-PDFF, a validated quantitative biomarker for liver fat. 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 out-patient clinic, who would primarily visit for management of type 2 diabetes and other co-morbidities. 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 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.

Detailed Description
OBJECTIVE Nonalcoholic fatty liver disease (NAFLD) is a public health problem in patients with type 2 diabetes mellitus (T2DM). The presence of type 2 diabetes in patients with NAFLD is a risk factor for its progression to a more severe liver disease known as nonalcoholic steatohepatitis (NASH). NASH, in turn, can progress to liver fibrosis, cirrhosis and hepatocellular cancer in some patients. GLP-1 receptor agonists are a class of anti-diabetic agents that reduce hyperglycemia and body weight. Liraglutide is a daily injectable GLP-1 receptor agonist that has been shown to reduce liver fat in patients with type 2 diabetes and NAFLD. Dulaglutide is a weekly injectable GLP-1 receptor agonist that is approved for type 2 diabetes. Data regarding the effect of dulaglutide on liver fat are scarce. Therefore, the present study is planned to evaluate the effect of dulaglutide on liver fat in patients with type 2 diabetes and nonalcoholic fatty liver disease.
Materials and methods Study design This D-LIFT (Effect of dulaglutide on Liver Fat) trial is an investigator initiated, prospective, open label, randomized clinical study to examine the effect of dulaglutide 0.75 mg subcutaneously weekly for 4 weeks, followed by 1.5 mg weekly for 20 weeks when included in the standard treatment for type 2 diabetes vs. standard treatment for type 2 diabetes (minus dulaglutide) in patients with type 2 diabetes and NAFLD. Hepatic steatosis (intracellular fat accumulation in hepatocytes) will be measured by MRI-PDFF, a validated quantitative biomarker for liver fat. 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 out-patient clinic, who would primarily visit for management of type 2 diabetes and other co-morbidities. 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 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 and physical examination.
Randomization A research assistant will randomize the patients into either dulaglutide group or control group in a 1:1 ratio using computer-generated numbers. SPSS software will be used to generate 60 random numbers between 000 to 999. The random numbers will be divided by 2 and the reminder noted. The reminders 0, & 1 will correspond to dulaglutide and control group respectively. It will be ensured that these are equal in number. Opaque envelopes will be prepared with serial number on the top and the assigned group inside the envelop. After recruiting the subjects, the envelop with corresponding serial number will be opened and the subjects assign to the relevant groups after opening the envelop. The patients will then be sent back to their respective consultants (MSK, SKM, KJF, AM) in the endocrine department for initiation and/or adjustment of treatment for type 2 diabetes (according to randomization into dulaglutide or control groups) and other co-morbidities. Treatment allocation will be open-label.
Study visits After careful assessment at the baseline visit, patients meeting all inclusion and exclusion criteria will be randomized to receive dulaglutide 0.75 mg weekly for 4 weeks followed by 1.5 mg weekly for 20 weeks plus standard treatment for type 2 diabetes. The control group will receive standard treatment for type 2 diabetes and up titration of treatment will be done by anti-diabetic medicines other than the GLP-1 receptor agonist. Patients will be advised to return to the out-patient endocrine clinic for follow-up visits at weeks 12 and 24.
Primary and secondary outcomes The primary outcome measure is change in liver fat quantified by MRI-PDFF in colocalized regions of interest (ROI) within each of the nine liver segments. The secondary outcome measures are change in serum AST, ALT and GGT values; Fibroscan, change in cardiometabolic markers namely IL-1, TNF-alpha, hs-CRP, leptin, adiponectin and homocysteine and fibrosis markers.
MRI-PDFF protocols MRI-PDFF for fat quantification MRI-PDFF is a non-invasive, objective, and quantitative MR imaging-based biomarker that can accurately estimate liver fat. MRI-PDFF has been demonstrated to be a robust technique for assessing treatment response in NASH clinical trials. In this study, the time interval from obtaining the baseline MRI-PDFF to initiating the study drug will be less than one week.
MRI-PDFF for detailed fat mapping of the entire liver All MR examinations will be done by an experienced MR technologist in the Medanta Radiology department under the direction of the radiologist investigator (SK). The radiologist investigator, blinded to the patients' treatment group allocation, clinical and biochemical data, and order of scans (baseline and follow-up), will perform the image analyses.
ROI colocalization before and after treatment To assess longitudinal changes in liver fat content, one colocalized ROI will be placed in each of the nine liver segments (nine separate ROIs) on the baseline and follow-up MRI examinations.
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.
Sample size calculation Investigator assumed that a 5% difference between dulaglutide and control groups would be the minimally appreciable and clinically relevant difference. Based on the results of previous similar clinical studies involving colesevelam and ezetimibe, Investigatorexpected the empagliflozin group to have a liver fat reduction of >5% compared to baseline, the control group to have <1% reduction in liver fat compared to baseline, and a dropout rate of <10%. With these assumptions the sample size per group works out as ≥20 to achieve a power of at least 90% with a β of 0.05. Therefore, Investigator plan to randomize 60 patents, 30 in each group to ensure adequate study power even with dropouts.
Method of sample size calculation
Assumptions:
Change in liver fat from baseline to week 20 in dulaglutide group (m1) = 5.0 unit Change in liver fat from baseline to week 20 in control group (m2) = 1.0 unit Confidence level -95% Power - 90% Coefficient of variation = 80%
Formula for sample size calculation:
n = (Zα+Zβ)2 * (σ12 + σ22)) / (m1-m2)2, where Zα is the value of normal distribution corresponding to desired confidence level Zβ is the value of the Normal distribution corresponding to desired power σ1 and σ2 are the standard deviation of the two groups With these assumptions the sample size per group works out as 20. Investigator will randomize 30 in each group to ensure adequate power even after dropouts.
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.
