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

Abstract

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 ∆9-tetrahydrocannabinol per puff; CBD/∆9-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.
