The LongitudinAl Nationwide stuDy on Management And Real-world outComes of diabetes in India over 3 years (LANDMARC trial).

INTRODUCTION: LANDMARC (CTRI/2017/05/008452), a prospective, observational real-world study, evaluated the occurrence of diabetes complications, glycemic control and treatment patterns in people with type 2 diabetes mellitus (T2DM) from pan-India regions over a period of 3 years. METHODS: Participants with T2DM (≥25 to ≤60 years old at diagnosis, diabetes duration ≥2 years at the time of enrollment, with/without glycemic control and on ≥2 antidiabetic therapies) were included. The proportion of participants with macrovascular and microvascular complications, glycemic control and time to treatment adaptation over 36 months were assessed. RESULTS: Of the 6234 participants enrolled, 5273 completed 3 years follow-up. At the end of 3-years, 205 (3.3%) and 1121 (18.0%) participants reported macrovascular and microvascular complications, respectively. Nonfatal myocardial infarction (40.0%) and neuropathy (82.0%) were the most common complications. At baseline and 3-years, 25.1% (1119/4466) and 36.6% (1356/3700) of participants had HbA1c <7%, respectively. At 3-years, population with macrovascular and microvascular complications had higher proportion of participants with uncontrolled glycemia (78.2% [79/101] and 70.3% [463/659], respectively) than those without complications (61.6% [1839/2985]). Over 3-years, majority (67.7%-73.9%) of the participants were taking only OADs (biguanides [92.2%], sulfonylureas [77.2%] and DPP-IV inhibitors [62.4%]). Addition of insulin was preferred in participants who were only on OADs at baseline, and insulin use gradually increased from 25.5% to 36.7% at the end of 3 years. CONCLUSION: These 3-year trends highlight the burden of uncontrolled glycemia and cumulative diabetes-related complications, emphasizing the importance of optimizing diabetes management in India.

Two-year trends from the LANDMARC study: A 3-year, pan-India, prospective, longitudinal study on the management and real-world outcome in patients with type 2 diabetes mellitus.

INTRODUCTION: There are limited data on the real-world management of diabetes in the Indian population. In this 2-year analysis of the LANDMARC study, the management of type 2 diabetes mellitus (T2DM) and related complications were assessed. METHOD: This multicenter, observational, prospective study included adults aged ≥25 to ≤60 years diagnosed with T2DM (duration ≥2 years at enrollment) and controlled/uncontrolled on ≥2 anti-diabetic agents. This interim analysis at 2 years reports the status of glycaemic control, diabetic complications, cardiovascular (CV) risks and therapy, pan-India including metropolitan and non-metropolitan cities. RESULTS: Of the 6234 evaluable patients, 5318 patients completed 2 years in the study. Microvascular complications were observed in 17.6% of patients (1096/6234); macrovascular complications were observed in 3.1% of patients (195/6234). Higher number of microvascular complications were noted in patients from non-metropolitan than in metropolitan cities (p < .0001). In 2 years, an improvement of 0.6% from baseline (8.1%) in mean glycated haemoglobin (HbA1c) was noted; 20.8% of patients met optimum glycaemic control (HbA1c < 7%). Hypertension (2679/3438, 77.9%) and dyslipidaemia (1776/3438, 51.7%) were the predominant CV risk factors in 2 years. The number of patients taking oral anti-diabetic drugs in combination with insulin increased in 2 years (baseline: 1498/6234 [24.0%] vs. 2 years: 1917/5763 [33.3%]). While biguanides and sulfonylureas were the most commonly prescribed, there was an evident increase in the use of dipeptidyl peptidase-IV inhibitors (baseline: 3049/6234, 48.9% vs. 2 years: 3526/5763, 61.2%). CONCLUSION: This longitudinal study represents the control of T2DM, its management and development of complications in Indian population. CLINICAL TRIAL REGISTRATION NUMBER: CTRI/2017/05/008452.

One-year trends from the LANDMARC trial: A 3-year, pan-India, prospective, longitudinal study on the management and real-world outcomes of type 2 diabetes mellitus.

INTRODUCTION: Longitudinal data on management and progression of type 2 diabetes mellitus (T2DM) in India are scarce. LANDMARC (CTRI/2017/05/008452), first-of-its-kind, pan-India, prospective, observational study aimed to evaluate real-world patterns and management of T2DM over 3 years. METHODS: Adults (≥25 to ≤60 years old at T2DM diagnosis; diabetes duration ≥2 years at enrolment; controlled/uncontrolled on ≥2 anti-diabetic agents) were enrolled. The first-year trends for glycaemic control, therapy and diabetic complications, including those from metropolitan and non-metropolitan cities are reported here. RESULTS: Of 6236 enrolled participants, 5654 completed 1 year in the study. Although the overall mean glycated haemoglobin (HbA1c) improved by 0.5% (baseline: 8.1%) at 1 year, only 20% of the participants achieved HbA1c <7%. Participants from metropolitan and non- metropolitan cities showed similar decrease in glycaemic levels (mean change in HbA1c: -0.5% vs. -0.5%; p = .8613). Among diabetic complications, neuropathy was the predominant complication (815/6236, 13.1% participants). Microvascular complications (neuropathy, nephropathy and retinopathy) were significantly (p < .0001) higher in non-metropolitan than metropolitan cities. Hypertension (2623/6236, 78.2%) and dyslipidaemia (1696/6236, 50.6%) continued to be the most commonly reported cardiovascular risks at 1 year. After 1 year, majority of the participants were taking only oral anti-diabetic drugs (OADs) (baseline: 4642/6236 [74.4%]; 1 year: 4045/6013 [67.3%]), while the proportion of those taking insulin along with OADs increased (baseline: 1498/6236 [24.0%] vs. 1 year: 1844/6013 [30.7%]). Biguanides and sulfonylureas were the most used OADs. The highest increase in use was seen for dipeptidyl peptidase-IV inhibitors (baseline: 3047/6236 [48.9%]; 1 year: 3529/6013 [58.7%]). Improvement in all glycaemic parameters was significantly (p < .0001) higher in the insulin vs. the insulin-naïve subgroups; in the insulin-naïve subgroup, no statistical difference was noted in those who received >3 vs. ≤3 OADs. CONCLUSIONS: First-year trends of the LANDMARC study offer insights into real-world disease progression, suggesting the need for controlling risk factors and timely treatment intensification in people with T2DM.

Baseline characteristics of participants in the LANDMARC trial: A 3-year, pan-india, prospective, longitudinal study to assess management and real-world outcomes of diabetes mellitus.

INTRODUCTION: Longitudinal data on progression, complications, and management of type 2 diabetes mellitus (T2DM) across India are scarce. LANDMARC (CTRI/2017/05/008452), the first pan-India, longitudinal, prospective, observational study, aims to understand the management and real-world outcomes of T2DM over 3 years. METHODS: Adults (≥25 to ≤60 years old at T2DM diagnosis; diabetes duration ≥2 years at enrollment; controlled/uncontrolled on ≥2 anti-diabetic agents) were enrolled. Baseline characteristics were analyzed using descriptive statistics. RESULTS: Of the 6279 recruited participants, 6236 were eligible for baseline assessment (56.6% [n/N = 3528/6236] men; mean ± SD age: 52.1 ± 9.2 years, diabetes duration: 8.6 ± 5.6 years). mean ± SD HbA1c, fasting plasma glucose, and postprandial glucose values were 64 ± 17 mmol/mol (8.1 ± 1.6%), 142.8 ± 50.4 mg/dl, and 205.7 ± 72.3 mg/dl, respectively. Only 25.1% (n/N = 1122/6236) participants had controlled glycemia (HbA1c < 53 mmol/mol, <7%). Macrovascular and microvascular complications were prevalent in 2.3% (n/N = 145/6236) and 14.5% (n/N = 902/6236) participants, respectively. Among those with complications, non-fatal myocardial infarction (n/N = 74/145, 51.0%) and neuropathy (n/N = 737/902, 81.7%) were the most reported macrovascular and microvascular complication, respectively. Hypertension (n/N = 2566/3281, 78.2%) and dyslipidemia (n/N = 1635/3281, 49.8%) were the most reported cardiovascular risks. Majority (74.5%; n/N = 4643/6236) were taking oral anti-diabetic drugs (OADs) only, while 24.4% (n/N = 1522/6236) participants were taking OADs+insulin. Biguanides (n/N = 5796/6236, 92.9%) and sulfonylureas (n/N = 4757/6236, 76.3%) were the most reported OADs. Basal (n/N = 837/6236, 13.4%) and premix (n/N = 684/6236, 11.0%) insulins were the most reported insulins. CONCLUSIONS: Baseline data from LANDMARC help understand the clinical/medical profile of study participants and underscore the extent of suboptimal glycemic control and prevalence of associated complications in a vast majority of Indians with T2DM.
