In triple therapy regimens (in combination with metformin and a sulphonylurea, or metformin and a thiazolidinedione), prolonged release exenatide is recommended as a treatment option for people with type 2 diabetes, when control of blood glucose remains or becomes inadequate (i.e. HbA1c ≥7.5%, or other higher level agreed with the individual), and the person has:
- A body mass index (BMI) ≥35 kg/m2 in those of European family origin (with appropriate adjustment for other ethnic groups) and specific psychological or medical problems associated with high body weight, or
- A BMI <35 kg/m2, and therapy with insulin would have significant occupational implications or weight loss would benefit other significant obesity-related comorbidities.
Treatment with prolonged-release exenatide in a triple therapy regimen should only be continued if a beneficial metabolic response has been shown, defined as a reduction of at least 1 percentage point in HbA1c and a weight loss of at least 3% of initial body weight at 6 months.
Prolonged-release exenatide in dual therapy regimens (in combination with metformin or a sulphonylurea) is recommended as a treatment option in people with type 2 diabetes, only if:
- The person is intolerant of either metformin or a sulphonylurea, or treatment with metformin or a sulphonylurea is contraindicated, and
- The person is intolerant of thiazolidinediones and dipeptidyl peptidase-4 (DPP-4) inhibitors, or treatment with thiazolidinediones and DPP-4 inhibitors is contraindicated.
Treatment with prolonged-release exenatide in a dual therapy regimen should only be continued if a beneficial metabolic response has been shown.
Exenatide prolonged release suspension is injected once weekly, as opposed to twice a day for the conventional formulation.
Final guidance is expected to be published in February 2012.
