BASAGLAR® (insulin glargine injection): Transitioning From Insulin Detemir

Based on analyses of trials, a dosage reduction may be warranted when transitioning from IDet to Basaglar.

Transitioning From Insulin Detemir to Basaglar

No dedicated trial has been conducted to investigate patients transitioning from IDet to Basaglar.

To compare insulin doses in patients treated with IGlar or IDet, Wallace et al conducted an analysis that included

  • 5 large RCTs in patients with T2DM, and

  • 2 large RCTs in patients with T1DM.1

To achieve similar glycemic control, patients treated with IDet required on average a 38% higher dose of insulin compared with patients treated with IGlar (Table 1).1

Dailey et al conducted a pooled analysis of 22 RCTs in patients with T2DM to compare insulin doses in patients treated with IGlar or IDet. To achieve a similar reduction in HbA1c levels, patients treated with IDet required a 31% higher mean insulin dose compared with patients treated with IGlar (Table 1).2

a Represents 5 RCTs in patients with T2DM and 2 RCTs in patients with T1DM.

b Data presented as mean (SE).

c Represents a 31% higher insulin dose vs IGlar.

Wallace et al concluded that since higher doses of IDet may be needed to obtain similar glycemic control, prescribers may consider a dosage reduction when transitioning from IDet to IGlar in order to reduce the risk of hypoglycemia that may result when using a unit-to-unit conversion.1

General Dosing Guidelines When Transitioning to Basaglar

If transitioning from a treatment regimen with an intermediate- or long-acting insulin, other than an IG-100 product, to a regimen with Basaglar,

  • a change in the dose of the basal insulin may be required, and

  • the amount and timing of shorter-acting insulins and doses of any antihyperglycemic medications may need to be adjusted.3
