Snapshot of real-world profile of Diabetic patient in India The mean age was 52.1 years , with 35% in the working age group, underscoring potential workplace productivity challenges due to T2DM. An average disease duration of 8.6 years. A BMI of 27.2 kg/m 2 and 2/3 rd being obese flags obesity as a significant comorbidity needing concurrent management. 75% having unregulated glycemia underlines the pressing need for more effective blood sugar management tools and awareness. 2.3% faced macrovascular issues, mainly non- fatal myocardial infarction , while 14.5% had microvascular complications, predominantly neuropathy. Approximately 75% of T2DM patients relying on multiple OADs emphasize the immediate need for early combination therapy and insulin usage to overcome clinical inertia. High prevalence of hypertension and dyslipidemia reported, imposing grave cardiovascular risks among the participants.

Vicious cycle of Uncontrolled glycemia-Complication-Uncontrolled glycemia Majority of patients had uncontrolled glycemia Patients with diabetic complications encountered greater challenges in reaching their target glycemic levels. Higher risk of developing diabetic complications Due to greater challenge in achieving glycemic target ther e is uncontrolled glycemia leading to more complications 01 02 04 03 How do we break this cycle?
Treatment Landscape: Evolving Antidiabetic Therapies and use of insulins Therapy
OAD, oral antidiabetic agents. M ajority of the participants were taking only OADs (baseline 67.66% to 36 months 73.86%) Addition of injectables (mostly insulin) was preferred in participants who were only on OADs at baseline. O ral and injectable anti-diabetic drugs categories The participants already on a combination of OADs and injectables had minimal shifts in their treatment and tended to continue with their ongoing combination of treatment. P articipants on injectables, showed h a lf of the participants (50.69%) continuing with basal insulin, and 37.77% and 14.04% of participants continuing with premix insulin and prandial insulin, respectively, over 36 months treatment period. 01 02 03 04

Translating learnings from LANDMARC into real practice
Rapidly Diminishing Efficacy of Newer Oral Antidiabetic Drugs – Attributed to Progressive β -cell Loss In a meta-analysis by Avogaro et al., DPP4 inhibitors showed an apparent accepted mean increase in HbA1c of 0.22% after 52 weeks of usage. Loss of glucose lowering efficacy after 2 years of treatment was observed with dapagliflozin A declining efficacy for SGLT2 inhibitors was also observed in a meta-analysis by Monami et al. over 104 weeks Decreasing efficacy of OADs Reference: Hanefeld M, et al. Diabetes Ther . 2020 Aug;11(8):1645–1666. Overreliance on OADs is problematic, underscoring the need for timely insulin initiation and treatment intensification
Multifaceted Benefits of Timely Initiation of Insulin Therapy Preserves β -cell mass and function Effectively controls the glucotoxic effects of hyperglycemia Improves insulin sensitivity Protects against endothelial dysfunction and damage that cause vascular disease Provides long-term protection to end organs via ‘metabolic memory’ Alters the course of disease progression in a positive manner Reference : Owens D.

Gla-100 Can Be a Solution to Tackle I nadequate Insulinisation!! Gla-100 regimen is Kalra S, et al. Indian J Endocrinol Metab . 2016;20(3):408–411. Freeman JS. J Am Osteopath Assoc . 2009;109(1):26 – 36. Flexible 1 Gla-100 provides mealtime flexibility as it involves only one injection per day and does not require adherence to a strict meal pattern. 1 Glargine can be injected at any time of the day, at the same time each day. 1 Simple 1 Less intrusive 1 Mimic physiological insulin 2 Hence, Gla-100 would be the ideal insulin to initiate in diabetic patients
