Response To Oral Agents in Diabetes (ROAD)- Pilot Study

Summary

This proposal is to fund a pilot study to assess feasibility and refine methodology for an intended large Scotland wide study on Response to Oral Agents in Diabetes (ROAD). The study will collect cohorts of patients who have carefully controlled standardised dose titration and monitoring with an assessment of drug response and side effects over a 6 month period. The primary aim will be to use these cohorts to investigate phenotypic and genotypic (pharmacogenetic) determinants of response. Drug naïve patients will be treated with Metformin. Patients who have failed on Metformin or are intolerant of Metformin will be randomised to gliclazide, pioglitazone or sitagliptin. With the ability to capture patient data beyond 6 months via data linkage we will monitor time to treatment failure and therefore compare which of the 3 oral agents is the best therapy to use after Metformin in a cost efficient and "real world" RCT.
