The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Empagliflozin Oral Tablet [Jardiance]
Treatment: Drugs - Placebo Oral Tablet

Active comparator: Phase 1 - Empagliflozin 10mg daily or placebo

Placebo comparator: Phase2 - Empagliflozin 10mg daily or placebo


Treatment: Drugs: Empagliflozin Oral Tablet [Jardiance]
Participants will be randomly assigned to receive either Empagliflozin 10mg/daily or Placebo and will later receive the alternate treatment. As the study is double blind neither the participant nor the study personnel will be aware of which treatment is currently being tested to avoid any effect this may have on the results. The two 4-week treatment phases will be separated by a 4-week wash out (drug-free) period. The study will consist of a total of 5 visits conducted over approximately 18 weeks; one screening visit, one baseline visit, 1 short visit at the start of the second treatment phase and 2 comprehensive testing visits, each at the end of the two treatment phases
