Safety and effectiveness of biphasic insulin aspart 30 in type 2 diabetes patients switched from biphasic human insulin 30: results from the Filipino cohort of the A₁chieve study.

Aim: To evaluate the safety and effectiveness of biphasic insulin aspart 30 (BIAsp 30) in Filipino patients with type 2 diabetes previously treated with biphasic human insulin 30 (BHI 30).

Methods: Safety and effectiveness outcomes were measured in all patients switching from BHI 30 to BIAsp 30 in the Filipino cohort of the 24-week, multinational, prospective, non-interventional A₁chieve study.

Results: A total of 111 Filipino patients (mean age ± SD, 57.4 ± 12.8 years; BMI, 25.8 ± 5.6 kg/m(2)) with mean diabetes duration of 9.9 ± 7.1 years switched therapy from BHI 30 to BIAsp 30. The mean pre-study BHI 30 dose was 0.65 ± 0.28 IU/kg and the baseline BIAsp 30 dose was 0.65 ± 0.26 U/kg titrated up to 0.70 ± 0.26 U/kg by Week 24. No serious adverse drug reactions were reported. Overall hypoglycaemia was reduced from 5.62 to 1.98 events/patient-year. Minor and nocturnal hypoglycaemia decreased and no major hypoglycaemia was reported at Week 24. Glucose control improved from baseline to Week 24 (HbA1c, -2.2 ± 2.1% [24 ± 23 mmol/mol]; FPG, -72.0 ± 71.8 mg/dL; PPPG, -145.5 ± 125.4 mg/dL). A total of 24 patients achieved HbA1c levels <7.0% at Week 24 compared to 6 patients reporting this target at baseline. Quality of life was positively impacted at Week 24 (change in visual analogue scores, 15.3 ± 16.9 points).

Conclusion: Switching from BHI 30 to BIAsp 30 improved glycaemic control without increasing the risk of hypoglycaemia.
