A Phase I Randomized, Double-blind, Placebo-controlled Study on Efficacy and Safety Profile of a Sublingually Administered Cannabidiol /Delta 9-tetrahydrocannabidiol (10: 1) Regimen in Diabetes Type 2 Patients.

The current study aimed to evaluate the safety profile and efficacy of a cannabis-based sublingual spray, CBDEX10 (containing 100 µg cannabidiol and 10 µg Δ-tetrahydrocannabinol per puff; CBD/Δ-THC 10:1), in improving lipid profile and glycemic state of the diabetic patients. Fifty diabetic patients were randomly allocated to the treatment (n = 25; receiving two puffs of CBDEX10 twice daily) or the control groups (n = 25; receiving two puffs of placebo). The primary endpoint of the study was to evaluate the efficacy of the CBDEX10 adjunctive therapy in improving the lipid profile and glycemic state of diabetic patients; the secondary endpoint was to assess the safety profile and tolerability of the spray. A statistically significant decline in total cholesterol [estimated treatment difference (ETD) = -19.73 mg/dL; P < 0.05], triglyceride (ETD = -27.84 mg/dL; P < 0.01), LDL-C (ETD = -5.37 mg/dL; P < 0.01), FBS (ETD = -12 mg/dL; P < 0.01), Hb A1C (ETD = -0.21 mg/dL; P < 0.01) and insulin secretion (ETD = -5.21 mIU/L; P < 0.01) was observable in the patients treated with CBDEX10 at the end of the 8-week treatment period. Regarding safety, the mentioned adjunctive regimen was well, and there were no serious or severe adverse effects. Overall, CBDEX1 sublingual spray could be a new therapeutic agent for lipid and glycemic control in diabetic patients.
