Reporting Groups
  Description
Subject-driven The subjects performed the titration of biphasic insulin aspart 30 (BIAsp 30) dose and administered subcutaneously (under the skin) using FlexPen® twice daily for 20 weeks. The starting dose of BIAsp 30 was subject’s previous basal insulin analogue dose split into two equal daily doses, immediately before breakfast and immediately before dinner. Directions for use were given to each subject at each dispensing visit. Subjects continued on their pre-trial metformin dose. Any previous basal insulin analogue and OAD (oral anti-diabetes drug) treatments (except for metformin) were discontinued. Metformin was allowed to be continued at the pre-trial dose with a total daily dose of at least 1500 mg or maximum tolerated dose (minimum 1000 mg) as prior to randomisation.
Investigator-driven The investigator performed the titration of biphasic insulin aspart 30 (BIAsp 30) dose and administered subcutaneously (under the skin) using FlexPen® twice daily for 20 weeks.
