Abstract Aims To compare the efficacy and safety of insulin degludec/insulin aspart (IDegAsp) and biphasic insulin aspart 30 (BIAsp 30) before, during and after Ramadan in patients with type 2 diabetes mellitus (T2DM) who fasted during Ramadan. Methods In this multinational, randomised, treat-to-target trial, patients with T2DM who intended to fast and were on basal, pre- or self-mixed insulin ± oral antidiabetic drugs for ≥90 days were randomised (1:1) to IDegAsp twice daily (BID) or BIAsp 30 BID. Treatment period included pre-Ramadan treatment initiation (with insulin titration for 8–20 weeks), Ramadan (4 weeks) and post-Ramadan (4 weeks). Insulin doses were reduced by 30–50% for the pre-dawn meal ( suhur ) on the first day of Ramadan, and readjusted to the pre-Ramadan levels at the end of Ramadan. Hypoglycaemia was analysed as overall (severe or plasma glucose Results During the treatment period, IDegAsp (n = 131) had significantly lower overall and nocturnal hypoglycaemia rates with similar glycaemic efficacy, versus BIAsp 30 (n = 132). During Ramadan, despite achieving significantly lower pre- iftar (meal at sunset) self-measured plasma glucose (estimated treatment difference: −0.54 mmol/L [−1.02; −0.07] 95% CI , p = .0247; post hoc ) with similar overall glycaemic efficacy, IDegAsp showed significantly lower overall and nocturnal hypoglycaemia rates versus BIAsp 30. Conclusions IDegAsp is a suitable therapeutic agent for patients who need insulin for sustained glucose control before, during and after Ramadan fasting, with a significantly lower risk of hypoglycaemia, versus BIAsp 30, an existing premixed insulin analogue.
