Sustained 52-week efficacy and safety of triple therapy with dapagliflozin plus saxagliptin versus dual therapy with sitagliptin added to metformin in patients with uncontrolled type 2 diabetes.

ABSTRACT: AIMS:To compare the efficacy and safety of an intensification strategy of early triple combination therapy with dapagliflozin (DAPA) plus saxagliptin (SAXA) to a dual therapy strategy with sitagliptin (SITA) in patients with type 2 diabetes who are inadequately controlled with metformin (MET) monotherapy. MATERIALS AND METHODS:This multinational, active-controlled, parallel-group phase 3b trial randomized 461 patients, at least 18?years of age, with glycated haemoglobin (HbA1c) of 8%-10.5% (64-91?mmol/mol), to either DAPA plus SAXA or SITA, added to MET, for a 26-week double-blind treatment period and an extension of a 26-week blinded treatment period. RESULTS:Mean (± SD) baseline HbA1c was 8.8%?± 0.9% (73.0 ± 9.3 mmol/mol). DAPA plus SAXA (n =?232) provided a greater reduction from baseline in HbA1c at Weeks 26 and 52 compared with SITA (n =?229) (adjusted mean?±?SE change, Week 26: -1.41?± 0.07% vs -1.07?± 0.07% [-15.4 ± 0.8 mmol/mol vs 11.7 ± 0.8 mmol/mol]; P = 0.0008; Week 52: -1.29?± 0.08% vs -0.81?± 0.09% [14.1 ± 0.9 mmol/mol vs 8.9 ± 1.0 mmol/mol]). The between-group difference in adjusted mean (95% CI) change from baseline in HbA1c increased from -0.34 (-0.54, -0.14) at Week 26 to -0.48 (-0.71, -0.25) at Week 52. DAPA plus SAXA was generally well tolerated and the incidence of adverse events was similar in both treatment arms. CONCLUSIONS:Early intensification to triple therapy with DAPA plus SAXA results in better, more durable glycaemic control than addition of SITA only (dual therapy) in patients with high HbA1c levels who are uncontrolled with MET monotherapy.

Project description:BACKGROUND:This study aim at evaluating the efficacy and safety of dapagliflozin plus saxagliptin vs monotherapy as added to metformin in patients with type 2 diabetes mellitus (T2DM). METHOD:PubMed, Cochrane library, Embase, CNKI and Wanfang databases were searched up to 31 December 2019. Randomized controlled trials (RCTs) applicable in dapagliflozin plus saxagliptin vs monotherapy as added to metformin in the treatment of T2DM were included. The outcomes included changes in HbA1c, FPG, body weight, SBP, DBP and adverse reactions. Fixed or random effects model were used to assess these outcomes. RESULTS:In this study, 8 RCTs involved 7346 patients were included. Compared with dapagliflozin plus metformin(DM) group, patients treated with dapagliflozin plus saxagliptin add on to metformin(DSM) could significantly increase the adjusted mean change levels of HbA1c, FPG, SBP and DBP(P?<?.00001, SMD?=?-4.88, 95%CI?=?-6.93?-2.83; P?<?.00001, SMD?=?-6.50, 95%CI?=?-8.55?-4.45; P?<?.00001, SMD?=?-0.97, 95%CI?=?-1.15?-0.78; P?<?.00001, SMD?=?-2.00, 95%CI?=?-2.20?-1.80), but no major difference in body weight loss showed(P?=?.12, SMD?=?0.92, 95%CI?=?-0.22?2.06). Furthermore, DSM therapy displayed better effects than saxagliptin plus metformin(SM) in the adjusted mean change levels of HbA1c, FPG, body weight and SBP(P?<?.00001, SMD?=?-7.75, 95%CI?=?-8.84?-6.66; P?<?.00001, SMD?=?-7.75, 95%CI?=?-8.84?-6.66; P?=?.04, SMD?=?-3.40, 95%CI?=?-6.64?-0.17; P?=?.04, SMD?=?-7.75, 95%CI?=?-8.84?-6.66), whereas no obvious difference in lowering DBP(P?=?.18, SMD?=?-16.35, 95%CI?=?-40.12?7.41). Additionally, compared with DM and SM groups, there were no remarkable difference in the incidence of nausea, influenza, headache, diarrhea, urinary tract infection and renal failure for patients taking DSM, but the incidence of genital infection and hypoglycemia were higher in DSM group. CONCLUSIONS:Patients taking the DSM therapy had better effects in reducing the level of HbA1c, FPG, body weight, SBP and DBP than the DM and SM therapy. However, patients treated with DSM therapy are more likely to have hypoglycemia and genital infection. Dapagliflozin plus saxagliptin may be a suitable therapy strategy for patients with T2DM inadequately controlled with metformin, and this will provide a clinical reference for the treatment of T2DM.
