Study Results

Participant Flow

Recruitment Details The study was conducted between 12-Jul-2017 and 20-Mar-2020. Patients who met all the inclusion and none of the exclusion criteria were enrolled in the study.
Pre-assignment Detail All study assessments were performed as per the schedule of assessment. No patients in Group 1 were enrolled into the Run-in set due to failure to meet inclusion exclusion criteria, screen failure, or other reasons. Due to unsatisfactory recruitment rate, it was decided that no more Group 1 patients would be enrolled in the study. Group 1 included type 2 diabetes mellitus (T2DM) patients with impaired kidney function and were to receive oral dose of dapagliflozin 10 mg/day from Day 1 to Day 14.
Arm/Group Title Group 2 Group 3
Arm/Group Description Type 2 diabetes mellitus (T2DM) patients with preserved kidney function received oral dose of dapagliflozin 10 mg/day from Day 1 to Day 14, following which they entered Follow-up Period from Day 15 to Day 19. Non-diabetic patients with impaired kidney function received oral dose of dapagliflozin 10 mg/day from Day 1 to Day 14, following which they entered Follow-up Period from Day 15 to Day 19.

Outcome Measure Data

Analysis Population Description
Evaluable patient set: all patients who dispensed at least one dose of study drug.

Limitations/Caveats

The study was prematurely closed due to unsatisfactory recruitment rate. Of 5 patients enrolled in the Group 1, none were enrolled into the Run-in set due to failure to meet inclusion/exclusion criteria, screen failure, withdrawal or other reason and hence it was decided that no more Group 1 patients would be enrolled in the study. In Group 2 and 3, 17 and 7 patients received the investigational product and completed the study, respectively.
