post-marketing surveillance study
type 1 diabetes mellitus
Background: With limited real-world insulin glargine 300 U/mL (Gla-300) data among Japanese patients with type 1 diabetes mellitus (T1DM) available, the authors describe its effectiveness and safety in Japanese T1DM patients switching to Gla-300.
Research design and methods: X-STAR was a 12-month prospective, observational, post-marketing study in Japanese patients with diabetes mellitus from 2015 to 2018: insulin-experienced T1DM patients initiating Gla-300 were analyzed.
Results: Of 774 patients, mean (±standard deviation) HbA1c (%) and fasting plasma glucose (mg/dL) decreased from 8.27 ± 1.55 to 8.15 ± 1.35 (by −0.12 ± 1.30 [p = 0.013]) and 167.9 ± 92.6 to 153.9 ± 70.9 (by −13.9 ± 103.8 [p = 0.067]) from baseline to month 12, respectively. A total of 16.3% achieved HbA1c <7.0% at month 12. Gla-300 dose increased by 1.13 ± 3.18 U/day (0.02 ± 0.05 U/kg/day) (p < 0.001), with a + 0.22 ± 2.70 (p = 0.037) body-weight change (kg) from baseline 60.83 ± 12.81 to 12-month 61.06 ± 12.89. Adverse drug reactions (ADRs) and serious ADRs occurred in 9.82% and 0.78% of the patients, respectively. Hypoglycemia was the most common ADR (9.30%). In total, 88.9% adhered to Gla-300 administration schedules, whereas <40% adhered to exercise and dietary instructions, respectively.
Conclusions: Gla-300 showed no unprecedented safety concerns for insulin-experienced T1DM patients in Japanese clinical settings. Our results provide insights into strategies for blunted Gla-300 up-titration dose, despite insufficient HbA1c control and lifestyle modification.
