Mean Urinary Glucose Excretion (UGE) | ||||||||||||||||||||||||||||||
End point description |
Urinary glucose excretion (UGE) is calculated from the measured individual subject urine glucose and urine volume data.

UGE0-24h is defined as cumulative daily urinary glucose excretion, equal to the amount of plasma glucose excreted into the urine over the entire urine collection interval, 0 to 24 hours, calculated as the sum of UGE0-12h and UGE12-24h.

Pharmacodynamic population set included all evaluable subjects who received at least 1 dose of study medication. The numeric value '999' indicates that on Day -1 (prior to treatment), many subjects had virtually no UGE and therefore their RTG values could not be determined. Values on Day -1 are shown only for the 2 subjects who had assessable values on this day.

Substantial protocol amendments (globally) |

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
18 Oct 2013 |
The overall reason for the amendment was to address a comment from the United states food drug adminstration (US FDA) regarding the definition of renal function inclusion criteria and general clarifications of admission days and a few procedures. The restriction on male subjects for use of effective birth control method was removed as per this amendment. |
||
30 Oct 2013 |
The overall reason for the amendment was to correct a typo defining the value of a non-acceptable estimated glomerular filtration rate (eGFR) and in exclusion criterion 8 Inclusion of contraceptive injection as an effective birth control method.
|
||
09 Sep 2014 |
The overall reason for the amendment was to adjust and clarify the language of the Inclusion and Exclusion criteria, modify rules related to concomitant medications, and update the calculation of estimated glomerular filtration rate (eGFR; using Schwartz formula). |
||
16 Sep 2014 |
The overall reason for the amendment was to ensure protocol consistency with health authority agreements for study design. Administration of antihyperglycemic agent (AHAs) for up to 7 days in the 8 to 2 weeks prior to the screening visit was not permitted as per this amendment. |
||
21 Sep 2015 |
The overall reason for the amendment was to enhance study recruitment. The window period for screening safety assessments was widened from 7 days to 10 days. Updated information on diabetic ketoacidosis and handling of subjects surrounding this event was added. Subjects who were on metformin XR for at least 8 weeks prior to screening and switched to metformin immediate release (IR; at the same total daily dose)which was well tolerated for at least 2 weeks prior to Day ‑1 were allowed to participate in the study. The concurrent use of insulin with metformin to achieve sufficient glycemic control was allowed. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
No notable study limitations were identified by the Sponsor. |
