Insights from VERIFY: Early Combination Therapy Provides Better Glycaemic Durability Than a Stepwise Approach in Newly Diagnosed Type 2 Diabetes.

ABSTRACT: The treatment aims for type 2 diabetes are to prevent complications and premature mortality, and improve quality of life. Glycaemic control is central to these aims; clinical guidelines have sought to achieve this with a stepwise approach starting with lifestyle measures and metformin, adding further medications once glycated haemoglobin (HbA1c) levels rise above a predefined threshold. However, treatment intensification can be delayed when HbA1c levels increase, and HbA1c levels become inadequately controlled in many patients. Clinical inertia can result in sustained elevated levels of HbA1c; when combined with a late diagnosis, this negatively impacts patients' prognosis. Early combination therapy using medications with complementary modes of action could achieve optimal glycaemic targets and alter the course of the disease more than metformin alone. The multinational VERIFY study (clinicaltrials.gov NCT01528254) provided evidence accrued over 5 years, demonstrating the potential of early combination therapy: time to loss of glycaemic control was nearly doubled, and more than twice the number of patients experienced extended glycaemic control, with a vildagliptin-metformin combination therapy versus metformin alone. The study also showed a delay in secondary treatment failure in patients receiving the combination. Early combination therapy therefore offers a different trajectory to the stepwise approach. Translating these findings into clinical practice will require early detection and diagnosis of type 2 diabetes plus a shift in disease management. Nonetheless, the potential benefits of sustained and continuous disease control that early combination therapy offers represent the start of a new era in early diagnosis and intensive management, to achieve the treatment aims of type 2 diabetes.

Project description:BackgroundPatients with type 2 diabetes mellitus (T2DM) from Latin American countries face challenges in access to healthcare, leading to under-diagnosis, under-achievement of glycemic target, and long-term complications. Early diagnosis and treatment initiation are of paramount importance in this population due to the high prevalence of risk factors such as obesity and metabolic syndrome. The VERIFY study in patients with newly diagnosed T2DM (across 34 countries), assessed the normoglycemic durability (5 years), with early combination (EC) therapy approach versus the traditional stepwise approach of initiating treatment with metformin monotherapy (MET). Here we present the results from the VERIFY study for participants from eight countries in Latin America.MethodsNewly diagnosed adult patients with T2DM, HbA1c 6.5-7.5% and body-mass index (BMI) of 22-40 kg/m2 were enrolled. The primary endpoint was time to initial treatment failure (TF; HbA1c ≥ 7.0% at two consecutive scheduled visits 13 weeks apart). Time to second TF was evaluated when patients in both groups were receiving and failing on the vildagliptin combination. Safety and tolerability were also assessed for both treatment approaches during the study.ResultsA total of 537 eligible patients (female, 58.8%) were randomly assigned to receive either EC (n = 266) or MET (n = 271). EC significantly reduced the relative risk of time to initial TF by 47% versus MET [HR (95% CI) 0.53 (0.4, 0.7) p < 0.0001]. Overall, 46.4% versus 66.3% of patients achieved the primary endpoint in the EC and MET groups, with a median [interquartile range (IQR)] time to TF of 59.8 (27.5, not evaluable) and 33.4 (12.2, 60.1) months, respectively. The risk for time to second TF was 31% lower with EC (p < 0.0092). A higher proportion of patients receiving EC maintained durable HbA1c < 7.0%, < 6.5%, and < 6.0%. Both treatment approaches were well tolerated, and only 3.2% of participants discontinued the study due to adverse events. All hypoglycemic events (EC: n = 7 and MET: n = 3) were single, mild episodes and did not lead to study discontinuation.ConclusionSimilar to the global population, long-term clinical benefits were achieved more frequently and without tolerability issues with EC versus standard-of-care MET in this Latin American sub-population. This study is registered with ClinicalTrials.gov, NCT01528254.
