Background: DISCOVER is an ongoing, observational study of people with T2D initiating second-line glucose-lowering therapy in 38 countries in six regions. We report changes in glucose-lowering therapies and HbA1c levels from the first to the second year of follow-up.

Methods: HbA1c levels and changes in therapies were recorded at baseline, 1 and 2 years; 15 988 patients were included in the analysis.

Results: Mean HbA1c levels at baseline, 1 and 2 years were 8.3%, 7.2% and 7.3%, respectively. At 1 and 2 years, mean HbA1c levels were close to 7.0% in patients receiving one or two oral drugs at 1 year, but were higher than 7.0% for those receiving more than two oral drugs or an injectable drug (Figure). The proportion of patients with HbA1c ≥ 8.0% was similar at 1 and 2 years (19.8% vs. 19.1%). Overall, 16.7% of patients changed therapy during the second year of follow-up. Treatment was intensified by the addition of an oral drug in 6.2% of patients receiving one or two oral drugs, and 3.2% of patients receiving oral therapies initiated an injectable drug. Results were consistent across regions.

Conclusions: Glycemic levels were well controlled after 1 and 2 years of follow-up in participants receiving oral therapies, and treatment intensification occurred in a small proportion of people in this group. By contrast, glycemic control was suboptimal in people receiving injectable drugs.
