ABSTRACT: Background
STELLA-LONG TERM was a 3-year post-marketing surveillance study that evaluated the long-term safety and effectiveness of ipragliflozin in Japanese patients with type 2 diabetes mellitus (T2DM). This subgroup analysis examined the safety and effectiveness of ipragliflozin in treatment-naïve and non-naïve patients.Materials and methods
Patients were stratified into two subgroups: treatment-naïve (patients who had not received any antidiabetic drugs before starting ipragliflozin monotherapy) and non-naïve (all other patients). Patients who had added or switched antidiabetic drugs during follow-up were excluded from the analysis from that point. The incidence of adverse drug reactions (ADRs) and changes from baseline in glycosylated hemoglobin (HbA1c), body weight, fasting plasma glucose (FPG) and laboratory parameters were assessed.Results
Of the 11,051 patients in the safety analysis set, 1980 patients (17.92%) were treatment-naïve and 9071 (82.08%) were non-naïve. In the safety analysis set, treatment-naïve patients reported significantly lower incidences of ADRs (10.81% vs 20.87%; p < 0.001) and serious ADRs (0.86% vs 2.09%; p < 0.001) compared with non-naïve patients, as well as significantly lower incidences of polyuria/pollakiuria, volume depletion-related events, skin complications and renal disorders. In the effectiveness analysis, sustained and significant reductions from baseline to 36 months were observed in HbA1c, FPG and body weight in both treatment-naïve and non-naïve patients (all p < 0.001 vs baseline).Conclusions
Over 3 years, ipragliflozin was better tolerated in treatment-naive than in non-naive Japanese patients with T2DM and had similar efficacy in these populations. Therefore, ipragliflozin is a useful first-line treatment option for patients with T2DM.Clinical trial registration
