• HbA1c level of >7% - ≤9% (53 - 74.9 mmol/mol).

• BMI of >25 - <40 (>23 - <40 for Asian populations).

• No changes in diet or exercise for three months prior to study entry and participant agrees to keep stable for the duration of the study.

• Participant is taking or has taken anti-diabetic treatment (other than metformin) in the three months prior to screening.

• Any concomitant medications which, in the opinion of the investigator, could affect the primary endpoint should remain stable or not be prescribed in the one month prior to Visit 1 or during the study period.

• Any known of suspected history of:

• Alcohol or substance abuse.

• Clinically significant cardiac, renal or hepatic impairment in the opinion of the investigator.

• Has significantly impaired renal function as evidenced by a creatinine clearance lower than 40 mL/min at Visit 1.

• Has significantly impaired hepatic function at Visit 1 (alanine aminotransferase (ALT) levels >5x upper limit of normal (ULN) or total bilirubin (TBL) levels > 2x ULN). If the ALT or aspartate aminotransferase (AST) levels are >3x ULN and the TBL levels >2x ULN (or International Normalised Ratio (INR) >1.5), then this participant should not enter the study.

• Any known or suspected hypersensitivity to cannabinoids or any of the excipients of the IMPs.
