This 15-19 week study is being conducted by GW Pharma Ltd as a pilot study in order to determine the efficacy and safety of two cannabinoids: GWP42004 and GWP42003 alone, or in combination in patients with Type 2 diabetes. This is the first study to determine whether the study medications have a positive benefit for subjects on their cholesterol levels, body weight, liver fat content and other metabolic parameters compared with a placebo medication.

In this study there was a 1-5 week baseline period followed by a 13 week treatment period, and a one week follow-up. Eligible subjects entered the study at a screening visit (Visit 1) before returning for randomisation (Visit 2, Day 1). At the discretion of the investigator (based on individual subjects), Visit 1 could be split into two separate visits (Visits 1A and B) to allow a 21-day washout period of prohibited medications prior to blood sampling for eligibility. Further outpatient study visits (for assessment purposes) took place at the study site at the end of Week 4 of treatment (Visit 3, Day 29), and at the overall end of treatment at Week 13 (Visit 5, Day 92). A telephone assessment was also performed at Day 57 (Visit 4) and at Week 14 (Visit 6, Day 99) for safety follow-up purposes.
During the 13 week randomised treatment phase, subjects received blinded, oral doses of their allocated randomised treatment twice daily. Treatment was self-administered on an outpatient basis, once in the morning and once in the evening for 13 weeks. Subjects were instructed to time study medication to 30 minutes before breakfast and evening meals.
Physical and metabolic parameters were assessed before, during and after treatment to evaluate clinical response. Diabetic and dyslipidaemic medication usage (where applicable), and appetite 0-10 NRS data were collected daily during the treatment period, using the study diary.

A two-hour OGTT was performed to investigate the rate of glucose metabolism or clearance from the blood with treatment. Blood samples were taken at -15 and 0 minutes prior to a glucose drink and at 30, 60, 90, 120 and 180 minutes post drink.

The BDI-II is a 21 question, multiple choice, self-reported inventory, and is one of the most widely used instruments for measuring the severity of depression. The 21 questions or items each had four possible responses. Each response was assigned a score ranging from zero to three, indicating the severity of the symptom, with a total possible score ranging from zero to 63. A score between zero and 13 indicates 'minimal depression'. A score between 14 and 19 indicates 'mild depression'. A score between 20 and 28 indicates 'moderate depression', and a score between 29 and 63 indicates 'severe depression'. As such, an increase from baseline to the end of treatment, a positive value, indicates a deterioration.
