Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment: 29-Oct-2010 to 04-Oct-2012. Original study had 3 arms but 5 mg dapagliflozin arm was discontinued with Protocol Amendment 8 (implemented 01-Nov-2011) because totality of data in development program showed that once daily 10-mg dapagliflozin provides optimal efficacy with safety and tolerance. Study continued to enroll with 2 arms.

Pre-Assignment Details

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Totality of data from dapagliflozin development program as of 1 NOV 2011 showed 10 mg dapagliflozin dose provided optimal efficacy, was safe and well tolerated for the general Type 2 diabetes population, allowing the 5 mg arm to be discontinued.
