About

This randomized controlled trial evaluated the efficacy of once-weekly trelagliptin compared to once-daily vildagliptin in reducing HbA1c levels in patients with type 2 diabetes mellitus (T2DM). A total of 102 participants, aged 30-60 years with HbA1c levels between 7.5% and 9.5%, were enrolled and randomly assigned to either the trelagliptin or vildagliptin group. The primary outcome measured was the percentage of participants achieving an HbA1c level of less than 7% after three months of treatment. Secondary outcomes included the mean reduction in HbA1c levels from baseline. The study aimed to determine whether trelagliptin, with its once-weekly dosing regimen, could improve medication adherence and glycemic control compared to the conventional daily administration of vildagliptin. Data were analyzed using SPSS version 26.0, with independent t-tests and chi-square tests employed for statistical comparisons. Findings from this study contributed to the understanding of the clinical effectiveness of weekly versus daily DPP-4 inhibitors in the management of T2DM.

Full description

Before the commencement of the study, ethical approval was obtained from the Institutional Review Board of the hospital. All study procedures adhered strictly to the ethical guidelines of both institutions, ensuring the confidentiality and privacy of all participant data. Potential study participants were provided with detailed information about the study protocols, including the objectives, procedures, potential risks, and benefits of participation. Informed consent was obtained from all participants who met the inclusion criteria and agreed to participate after fully understanding the study details. Participants were diagnosed with type 2 diabetes according to standard diagnostic criteria as per the operational definition. A detailed history was taken to gather basic demographic and clinical data such as age, gender, and comorbidities. Baseline laboratory investigations, including liver function tests (LFTs), renal function tests (RFTs), serum electrolytes, and fundoscopy, were conducted to ensure participants met the selection criteria.

Eligible participants were randomly assigned to one of two treatment groups (Group A or Group B) using a lottery method to ensure equal and unbiased distribution.

Group A received trelagliptin 100 mg once weekly before breakfast on the same day of the week. Group B received vildagliptin 50 mg once daily. Both groups followed the prescribed treatment regimen for a duration of three months. Participants were followed up at three months of treatment. Outcome assessments included monitoring the mean reduction in HbA1c levels and evaluating the efficacy of the treatment, aiming for an HbA1c level of less than 7% after three months of treatment. Data were collected using a data collection proforma.
