Subject: Participation in study “Evaluation of drug utilization pattern of Voglibose and its combinations in type 2 Diabetes Mellitus patients (V-FIT-II)”


Type 2 Diabetes Mellitus (T2DM) is a complex chronic disease which requires multiple pharmacological interventions to control glucose level and prevent further complications. Diabetes is a major risk factor for cardiovascular disease (CVD). Patients with type 2 diabetes have a 2–4 times higher risk of CVD mortality than those without diabetes


India is home to 74.2 million diabetic individuals, the burden of diabetes in India is of epidemic proportions. Indians have high genetic predisposition, high susceptibility to environmental insults, and early onset of the disease. In India, we see largely diverse life style, food pattern and activities, with diet pattern traditionally having a high glycemic index. Carbohydrates constitute 64.1% of total energy from diet in T2DM participants, higher than that recommended in Indians


Postprandial Hyperglycemia (PPH) contributes over 50 % to HbA1c at A1C < 8.4 %. PPH is often seen in individuals with an apparently good glycemic control (HbA1c <7%) & average fasting glucose levels within recommended goals (</=120mg/dl). The outcomes from Chicago HEART Association study, DECODE, and Diabetes Intervention study have clearly stated that post meal glucose surge has increased mortality and cardiovascular complications in patients with Diabetes Mellitus.


Voglibose, a ɑ-glucosidase inhibitor, controls PPG level and has cardiovascular benefits. Its systemic absorption is negligible hence it is ideal for elderly and those with hepatic complications. Despite its accepted benefits & efficacy, the usage of Voglibose in routine clinical practice remains undetermined.


Real-world evidence on management of post prandial hyperglycemia can help bridge the evidence gap by providing better insights for drug utilization patterns of Voglibose, drug adherence, comorbidities, and effects of switching or adjusting medications in the real world. Currently, there is limited evidence on utilization pattern of Voglibose. This study is planned to evaluate drug utilization pattern of voglibose and the prevalence of post prandial hyperglycemia in T2DM patients in India.


We invite you to participate in this study. On acceptance, you will need to capture the relevant data as mentioned in the standard Data Collection Form (DCF) provided, from the patient’s medical records (case papers and investigational reports – hereafter referred as source documents).


We would recommend you to capture data fulfilling the criteria as outlined in the protocol and whose relevant laboratory investigations are available for the preceding 3 months. We wish to inform you that the DCF will capture all data in de-identified form and any identifiable parameters which may potentially disclose the identity of the patient such as name or address will strictly not be captured so as to ensure we maintain patient confidentiality. We would encourage you to carefully fill all available information to the fullest as recommended in the DCF.


In alignment with good clinical research practices, an independent CRO will monitor this study and do the source data verification of the data captured in the DCF with copies of the patients’ source medical records (case papers and investigational reports) to ensure that the data entered in the DCFs are accurate and in alignment with the patients’ medical records.


If you agree to participate in the said study, we would request you to sign and return the enclosed reply along with your visiting card for accuracy of records.
