RESUMO
AIMS: Two fixed-ratio combinations (FRCs) of basal insulin and glucagon-like peptide-1 receptor agonist (GLP-1RA) are available for once-daily use in adults with type 2 diabetes. We aimed to review the clinical evidence for the efficacy and safety of changing treatment from a basal-bolus insulin (BBI) regimen or a premix insulin to these combination treatments (fixed-ratio or loose) and provide expert opinion on the practicalities of making such a change. METHODS: Relevant clinical and trial evidence and general review articles were identified through a literature review of ProQuest (comprising BIOSIS Previews®, Current Contents® Search, Embase® and MEDLINE®) for articles published between 2009 and 2021. RESULTS: We identified nine articles reporting the results of FRCs, and seven articles reporting results of loose combinations of basal insulin and GLP-1RAs, in people who transitioned treatment from BBI or premix regimens. In most trials, combination treatment led to improved or equivalent glycaemic control, and a reduction in body weight or BMI, versus the original regimens. Some trials reported a reduction in total insulin dose. A few trials reported reduced or unchanged hypoglycaemia rates, or increased patient satisfaction, with combination therapy where these endpoints were examined. We provide guidance on transitioning of treatment and the patient types most likely to benefit. CONCLUSIONS: In people not achieving glycaemic control with BBI or premix insulin regimens, an FRC or loose combination of basal insulin and GLP-1RA may improve control, decrease the risk of body weight gain or hypoglycaemia and reduce the complexity of treatment.

Lixisenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, is used in the treatment of type 2 diabetes mellitus (T2DM). It increases insulin (INS) secretion and can decrease INS resistance, improving metabolic disorders in this disease. However, its effects on metabolic disturbances in cancer-bearing, which also exhibit decreased INS secretion and INS resistance, changes that may contribute to weight loss (cachexia), have not yet been evaluated. The purpose of this study was to investigate the lixisenatide treatment effects on mild cachexia and related metabolic abnormalities in Walker-256 tumour-bearing rats. Lixisenatide (50 µg kg-1 , SC) was administered once daily, for 6 days, after inoculation of Walker-256 tumour cells. Acute lixisenatide treatment did not improve hypoinsulinemia, INS secretion and INS resistance of tumour-bearing rats. It also did not prevent the reduced glucose and increased triacylglycerol and lactate in the blood and nor the loss of retroperitoneal and epididymal fat of these animals. However, acute lixisenatide treatment accentuated the body mass loss of tumour-bearing rats. Therefore, lixisenatide, unlike T2DM, does not improve hypoinsulinemia and INS resistance associated with cancer, evidencing that it does not have the same beneficial effects in these two diseases. In addition, lixisenatide aggravated weight loss of tumour-bearing rats, suggesting that its use for treatment of T2DM patients with cancer should be avoided. SIGNIFICANCE OF THE STUDY: Lixisenatide increases insulin secretion and appears to reduce insulin resistance in T2DM. However, lixisenatide treatment does not improve hypoinsulinemia and insulin resistance associated with cancer, as it does in T2DM, and aggravated weight loss, suggesting that its use for treatment of T2DM patients with cancer should be avoided.

AIM: To evaluate the efficacy and safety of iGlarLixi in Mexican patients with type 2 diabetes who participated in the LixiLan clinical trials and compare results with the rest of the patients. METHODS: Data was collected for Mexican patients who participated in either of three studies: phase 2 trial LixiLan-POC, that compared iGlarLixi vs insulin glargine (iGlar) on inadequately controlled patients with metformin; phase 3 trial LixiLan-O, comparing iGlarLixi vs iGlar and lixisenatide on inadequately controlled patients with oral antidiabetic agents; and finally the phase 3 trial LixiLan-L, comparing iGlarLixi vs iGlar on inadequately controlled patients with basal insulin. The primary endpoint was the change in HbA1c from baseline to end of treatment. RESULTS: In the Mexican population, treatment with iGlarLixi significantly improved HbA1c compared with each component alone achieving an average of 6.5%; (6.17%, 6.63% and 6.73% for the LixiLan-POC, O and L studies respectively) and an average HbA1c reduction from baseline of 1.6%, for the three studies at end of treatment period. CONCLUSION: The efficacy and safety profile of iGlarLixi demonstrate a fair or better composite endpoint of HbA1c without hypoglycemia and no weight gain compared to overall trial population, which could help improve Mexican patients' outcomes.
