Abstract BACKGROUND: Combination treatment with a glucagon-like peptide-1 (GLP-1) agonist and basal insulin has been proposed as a treatment strategy for type 2 diabetes that could provide robust glucose-lowering capability with low risk of hypoglycaemia or weight gain. We thus did a systematic review and meta-analysis of randomised controlled trials to assess the effect of this combination treatment on glycaemic control, hypoglycaemia, and weight gain in patients with type 2 diabetes. METHODS: We systematically searched PubMed, Embase, Cochrane, Web of Knowledge, FDA.gov, and ClinicalTrials.gov for randomised controlled trials (published between Jan 1, 1950, and July 29, 2014; no language restrictions) comparing GLP-1 agonist and basal insulin combination treatment to other anti-diabetic treatments. Our main endpoints were glycaemic control, hypoglycaemia, and change in weight. We assessed pooled data by use of a random-effects model. FINDINGS: Of 2905 identified studies, 15 were eligible and were included in our analysis (N=4348 participants). Compared with other anti-diabetic treatments, GLP-1 agonist and basal insulin combination treatment yielded an improved mean reduction in glycated haemoglobin (HbA1c) of -0·44\% (95\% CI -0·60 to -0·29), an improved likelihood of achieving the target HbA1c of 7·0\% or lower (relative risk [RR] 1·92; 95\% CI 1·43 to 2·56), no increased relative risk of hypoglycaemia (0·99; 0·76 to 1·29), and a mean reduction in weight of -3·22 kg (-4·90 to -1·54). Furthermore, compared with basal-bolus insulin regimens, the combination treatment yielded a mean reduction in HbA1c of -0·1\% (-0·17 to -0·02), with lower relative risk of hypoglycaemia (0·67, 0·56 to 0·80), and reduction in mean weight (-5·66 kg; -9·8 to -1·51). INTERPRETATION: GLP-1 agonist and basal insulin combination treatment can enable achievement of the ideal trifecta in diabetic treatment: robust glycaemic control with no increased hypoglycaemia or weight gain. This combination is thus a potential therapeutic strategy that could improve the management of patients with type 2 diabetes. FUNDING: None. Copyright © 2014 Elsevier Ltd. All rights reserved.
