БЕЗОПАСНОСТЬ И ЭФФЕКТИВНОСТЬ ИПРАГЛИФЛОЗИНА У ПАЦИЕНТОВ ИЗ ЯПОНИИ С САХАРНЫМ ДИАБЕТОМ 2-ГО ТИПА И НАРУШЕНИЕМ ФУНКЦИИ ПОЧЕК: АНАЛИЗ В ПОДГРУППАХ 3-ЛЕТНЕГО ПОСТМАРКЕТИНГОВОГО НАБЛЮДАТЕЛЬНОГО ИССЛЕДОВАНИЯ (STELLA-LONG TERM)

STELLA-LONG TERM, a 3-year post-marketing surveillance study, evaluated the safety and effectiveness of the sodiumglucose cotransporter 2 inhibitor ipragliflozin in Japanese type 2 diabetes mellitus (T2DM) patients. Final results in the safety (n = 6697) and effectiveness populations (n = 5625) were analyzed by stratifying patients by baseline estimated glomerular filtration rate (eGFR, mL/min/1.73 m²) into four subgroups (≥90, 60 to <90, 45 to <60, and <45) and two subgroups (≥60 and <60). Adverse drug reaction (ADR) incidence, and changes from baseline in glycosylated hemoglobin (HbA_1c), bodyweight, and eGFR were assessed. The percentage of patients experiencing ADRs and serious ADRs was similar across most eGFR subgroups. Polyuria/ pollakiuria was the most common ADR. Renal disorders and volume depletion ADRs were more frequent in the subgroups with more severe renal impairment at baseline than in those with an eGFR of 60 to <90 or ≥90 mL/min/1.73 m². Bodyweight and HbA_1c decreased in all subgroups, the latter by - 0.91% to - 0.40% (P <0.05 vs. baseline). eGFR increased in the 45 to <60 mL/min/1.73 m² subgroup (+ 1.42 ± 8.77 mL/min/1.73 m²; P = 0.006). It decreased in the ≥90 and 60 to <90 mL/min/1.73 m² subgroups (- 8.27 ± 13.73 and - 1.22 ± 10.34 mL/min/1.73 m²; P <0.001), but not to <60 mL/min/1.73 m². In conclusion, there were no new or unexpected safety findings in Japanese patients treated with ipragliflozin for T2DM, and long-term sustained improvements in HbA_1c and bodyweight were observed regardless of the presence of renal impairment.
