Original Article



We aimed to identify diabetes-related factors associated with achieving HbA1c <7.0 % after the initiation of basal supported oral therapy (BOT) in insulin-naïve type 2 diabetes patients with an HbA1c value of ≥6.5 % during the previous 4 weeks, using data from Add-on Lantus® to Oral Hypoglycemic Agents 2 (ALOHA2) study, a 24-week observational study on Japanese type 2 diabetes patients.


Patients were categorized into two groups: HbA1c <7.0 % at the final evaluation point (at 24 weeks or the last visit) as HbA1c-target-achieved; HbA1c ≥7.0 % as target-not-achieved. Associations between baseline factors and HbA1c <7.0 % achievement were explored using logistic regression.


Of the 1520 patients in the study, 400 patients (26.3 %) achieved HbA1c <7.0 %. Patients with diabetes duration of <1 year and between ≥1 and <2 years [odds ratio (OR): 5.27, 95 % confidence interval (CI): 1.13–24.51; OR: 3.77, 95 % CI 1.19–11.93, respectively], those on one pre-study orally administered antidiabetic agent (OAD) (OR: 2.42, 95 % CI 1.12–5.22), and those with absence of diabetic neuropathy (OR: 2.54, 95 % CI 1.12–5.76) were more likely to achieve HbA1c <7.0 % than those with duration of ≤15 years, ≥4 pre-study OADs, and neuropathy, respectively. Achievement of HbA1c <7.0 % among patients increased by approximately 20 % for each 1 % decrease in HbA1c level at baseline.


Shorter diabetes duration, pre-study regimen of one OAD, absence of neuropathy, and lower HbA1c level at baseline were associated with achievement of HbA1c <7.0 %, suggesting that earlier initiation of BOT leads to good HbA1c control in insulin-naïve Japanese type 2 diabetes patients, consistent with our early ALOHA study.
