Curalin supplement as add-on therapy for type 2 diabetes Mellitus

Aims: To examine the efficacy and safety of Curalin, as a supplement to anti-diabetic drugs (ADD). Methods: 135 patients were enrolled in the study. Among them, 109, ages 18–85 years, with HA1c 7.5–10 % under treatment with ADD were randomized 1:1 to receive Curalin supplement or placebo. The primary efficacy endpoint was the change in HbA1c after 3 months. The secondary endpoint was a decrease in HbA1c by more than 0.5 % and by more than 1 %. The exploratory endpoints included the Diabetes Treatment Satisfaction Questionnaire (DTSQ), clinical and laboratory results. Results: After 3 months, the mean reduction in HbA1c was 1.30 % (SD = 0.79) in the Curalin group compared to 0.10 % (SD = 0.70) in the placebo group (P < 0.0001). A decrease in HbA1c of ≥ 0.5 % was observed in 90.0 % of Curalin patients versus 19.0 % of placebo patients (P < 0.0001). HbA1c reduction of ≥ 1 % occurred in 64.0 % of Curalin patients and 11.9 % of placebo patients (P < 0.0001). Curalin patients reported higher satisfaction (DTSQ) with no severe adverse events. Conclusions: Curalin treatment significantly reduced HbA1c over a period of 3 months and was well-tolerated.
