Exenatide in type 2 diabetes mellitus — evidence extract
The Institute's graded assessment of Exenatide for type 2 diabetes mellitus, with the contributing trials and the domain-by-domain certainty reasoning.
§1Evidence extract: Type 2 diabetes mellitus
§1.1Question and anchor outcome
- Population
- A disorder of glucose regulation characterised by insulin resistance with relative insulin deficiency, diagnosed by glycated haemoglobin, fasting plasma glucose or oral glucose tolerance criteria.
- Intervention
- Exenatide, subcutaneous twice daily (immediate release) or once weekly (poly(lactide-co-glycolide) microsphere extended release)
- Comparator
- As used in each contributing trial; reported per trial rather than pooled across comparator types
- Anchor outcome
- Change in HbA1c (%, mmol/mol)
Additional outcomes the Institute extracts for this indication: Proportion achieving HbA1c <7.0 % and ≤6.5 %; Change in fasting serum glucose; Change in body weight; Documented symptomatic hypoglycaemia.
§1.2Contributing trials
Table 1. Trials contributing to the assessment of Exenatide in type 2 diabetes mellitus.
| Trial | Phase | Design | Randomised | Duration | Year |
|---|---|---|---|---|---|
| DURATION-1 | 3 | Randomised, open-label, active-controlled | 295 | 30 weeks | 2008 |
| DURATION-6 | 3 | Randomised, open-label, active-controlled | 911 | 26 weeks | 2013 |
| AMIGO-1 | 3 | Randomised, double-blind, placebo-controlled | 377 | 30 weeks | 2005 |
§1.3Certainty assessment
Table 2. Reasoning recorded against each certainty domain.
| Domain | Rating | Reasoning |
|---|---|---|
| Risk of bias | No concern | No serious concern identified in this domain. |
| Inconsistency | No concern | No serious concern identified in this domain. |
| Indirectness | No concern | No serious concern identified in this domain. |
| Imprecision | No concern | No serious concern identified in this domain. |
| Publication bias | No concern | No serious concern identified in this domain. |
| Overall rating: High certainty. The Institute is confident that the true effect lies close to the estimate. Further research is very unlikely to change confidence in the estimate. | ||
