Abstract

While Muslims with serious medical conditions, including some people with diabetes, are exempt from Ramadan fasting (no food or drink from dawn to sunset), many continue to fast. This intermittent fasting puts patients at high risk of developing dehydration, hypoglycemia and overt hyperglycemia. Due to this concern, patient recruitment for clinical trials taking place during Ramadan is challenging and trials on insulin use during Ramadan are scarce. IDegAsp, a new co-formulation of insulin degludec and insulin aspart is associated with a reduced risk of hypoglycemia compared with BIAsp 30 (NovoLog® Mix 70/30) due to the flat pharmacokinetic profile and long duration of action of insulin degludec. This international, randomized, treat-to-target trial is the first to compare the efficacy and safety of two insulin analogues (IDegAsp and BIAsp 30) during Ramadan in countries with a large Muslim population.

Patients with type 2 diabetes (T2D) who intended to fast and were on basal, pre-mixed or self-mixed insulin ± oral antidiabetic drugs for ≥90 days, were randomized (1:1) to IDegAsp twice daily (BID) or BIAsp 30 BID. Treatment duration was up to 28 weeks (treatment initiation, 8–20 weeks pre-Ramadan; Ramadan, 4 weeks; post-Ramadan, 4 weeks). Insulin doses were titrated to achieve a plasma glucose (PG) target of 4–5 mmol/L during the initiation period and 5–7 mmol/L during Ramadan. At the start of Ramadan, a 30–50% reduction of one of the two doses of both insulins was recommended. Hypoglycemia was recorded as severe (requiring third-party assistance), nocturnal (any hypoglycemia occurring 00:01–05:59) or overall (severe or PG <3.1 mmol/L [56 mg/dL]).

In total, 263 patients were randomized to IDegAsp (n=131) or BIAsp 30 (n=132). IDegAsp was non-inferior to BIAsp 30 in HbA1creduction from baseline to end of Ramadan. During the 28-week treatment period, rates of overall and nocturnal hypoglycemia, respectively, were 74% and 83% lower with IDegAsp vs. BIAsp 30. The rates of severe hypoglycemia per 100 patient years of exposure were 8.33 with IDegAsp and 16.33 with BIAsp 30.

During the month of Ramadan, there was a 62% lower rate of overall hypoglycemia with IDegAsp vs. BIAsp 30; rate ratio (RR) 0.38 (95% CI: 0.19; 0.77). The rate of nocturnal hypoglycemia was 74% lower with IDegAsp vs. BIAsp 30; RR 0.26 (95% CI: 0.08; 0.88).

In conclusion, this trial in a high-risk population of patients with T2D fasting during Ramadan showed similar efficacy of IDegAsp and BIAsp 30 in controlling blood glucose during and after Ramadan. IDegAsp, however, was associated with lower rates of overall and nocturnal hypoglycemia vs. BIAsp 30.
