Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The trial was conducted at 48 sites in Japan.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Subjects continued on not more than 2 oral antidiabetic drugs (excluding sulphonylureas/dipeptyl peptidase-4 [DPP-4] inhibitors/glinides) at the pre-randomisation dose level and dosing frequency.

Reporting Groups

	Description
IDegAsp OD	Insulin degludec/insulin aspart (IDegAsp) was given subcutaneously once daily (OD) either as monotherapy or in combination with no more than 2 oral antidiabetic drugs (excluding sulphonylureas/DPP-4 inhibitors/glinides). IDegAsp was given just prior to the largest meal of the day. Insulin doses were individually adjusted.
IGlar OD	Insulin glargine (IGlar) was given once daily (OD) according to approved labelling either as monotherapy or in combination with no more than 2 oral antidiabetic drugs (excluding sulphonylureas/DPP-4 inhibitors/glinides). IGlar was given before breakfast or at bedtime but at the same time each day. Insulin doses were individually adjusted.
