Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an exploratory randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of MEDI0382 versus placebo in overweight/obese participants with T2DM treated with metformin and dapagliflozin dual therapy. The study will enroll participants with T2DM treated either with metformin monotherapy or with metformin and dapagliflozin dual therapy. After the screening period, participants treated with metformin monotherapy only will enter a 4-week run-in period where participants will be administered oral dapagliflozin 10 mg a day, which will be provided by the sponsor. Enrolled participants that are already treated with metformin and dapagliflozin dual therapy will continue this dual therapy throughout the study and can be randomized after the screening period without entering the run-in period. All participants (ie, on monotherapy and dual therapy) entering the double-blind treatment period will receive dapagliflozin 10 mg a day, which will be provided by the sponsor.

Participants in this study will participate for up to 20 weeks including a screening period of up to 60 days, a 4-week run-in period (for participants on metformin monotherapy only), a 4-week treatment period, and a 4-week follow-up post-treatment period.

5. Diagnosed with T2DM and treated with of metformin monotherapy (MTD \> 1 g) at least 8 weeks prior to screening or treated with stable, oral doses of dapagliflozin 10 mg and metformin (MTD \> 1 g) for at least 3 months prior screening.
6. Participants prescribed oral dual therapy with sulphonylurea, glitinide, or dipeptidyl peptidase-4 inhibitor (in addition to metformin) may be eligible to enter the study following a washout period of these medications totaling at least 28 days before initial screening evaluations have been completed.
7. Participants treated with stable doses of metformin (MTD \> 1 g) with canagliflozin (maximum dose of 300 mg/day), or metformin (MTD \> 1 g) with empaglifozin (maximum dose of 25mg/day) for at least 3 months prior to screening may be eligible to enter the study after switching to dapagliflozin.
8. Female participants of childbearing potential must have a negative pregnancy test at screening and randomization and must not be lactating.
9. Females of childbearing potential who are sexually active with a nonsterilized male partner must use at least one highly effective method of contraception from screening and must agree to continue using such precautions through to the end of the study. It is strongly recommended for the male partner of a female participant to also use male condom plus spermicide throughout this period. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception.
