Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations

The main/extension trial periods were conducted at 71/68 sites in 6 countries:

Belgium (5/5 sites), Germany (7/7 sites), Norway (5/5 sites), Poland (5/5 sites), United Kingdom (UK) (12/11 sites), and United States of America (U.S.) (37/35 sites). 57 patients did not participate in the extension trial.


Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
All subjects who completed the 26-week main trial and were found to be eligible for the extension trial were offered to participate in the 26-week extension trial (NCT01079234). Total duration of trial was up to 52 weeks (26 weeks+ 26 weeks) with two times 7-12 day follow-up periods.

Reporting Groups
  Description
IDeg OD FF Insulin degludec (IDeg) was given once daily (OD) subcutaneously (s.c.) with alternating morning and evening dosing according to a fixed flexible (FF) schedule (approximately 8-40 hours intervals) in combination with insulin aspart (IAsp) for 26 weeks in main period. Insulin doses were individually adjusted by the subjects.
IDeg OD Insulin degludec (IDeg) was given once daily (OD) subcutaneously (s.c.) with the evening meal in combination with insulin aspart (IAsp) for 26 weeks in main period. Insulin doses were individually adjusted by the subjects.
IGlar OD Insulin glargine (IGlar) was given once daily (OD) subcutaneously (s.c.) according to local labelling in combination with insulin aspart (IAsp) for 52 weeks (26 weeks in main period + 26 weeks in extension period). Insulin doses were individually adjusted by the subjects.
IDeg OD F The subjects randomised to the 2 insulin degludec (IDeg) treatment arms in the main period (IDeg OD FF and IDeg OD) were pooled into this IDeg OD Free Flex arm (IDeg OD F). IDeg was given once daily (OD) subcutaneously (s.c.) at any time of the day (approximately 8-40 hours intervals) in combination with insulin aspart (IAsp) for 26 weeks in the extension period (52 weeks in total). Insulin doses were individually adjusted by the subjects.
