Insulin glargine is a synthetic long-acting insulin product used for patients with diabetes mellitus. In this study, to obtain the further desirable blood-glucose lowering profile of insulin glargine, we investigated the effects of β-cyclodextrin sulfate (Sul-β-CyD) and sulfobutylether β-cyclodextrin (SBE7-β-CyD) on physicochemical properties of insulin glargine and pharmacokinetics/pharmacodynamics of insulin glargine after subcutaneous injection to rats. Sul-β-CyD and SBE7-β-CyD increased solubility of insulin glargine. SBE7-β-CyD suppressed the formation of oligomer and enhanced the dissolution rate of insulin glargine from its precipitate, compared to that of Sul-β-CyD. Additionally, we revealed that after subcutaneous administration of an insulin glargine solution, SBE7-β-CyD, but not Sul-β-CyD, increased bioavailability and sustained the blood-glucose lowering effect, possibly due to the inhibitory effects of SBE7-β-CyD on the enzymatic degradation at the injection site. These results suggest that SBE7-β-CyD could be a useful excipient for sustained release of insulin glargine.

This case report presents a rare instance of a 28-year-old female patient with insulin-induced abdominal lipodystrophy, who presented to the emergency department with symptoms of an anxiety attack triggered by body image distress. She was diagnosed with type 1 diabetes at the age of eight years. For the past 10 years, she has been using insulin glargine and insulin lispro, injecting roughly five times per day.

Aims: This study assessed efficacy and safety of the fixed ratio combination iGlarLixi 100/33 (insulin glargine 100 U/mL plus lixisenatide 33 μg/mL) in people with type 2 diabetes (PwT2D) in daily clinical practice.
Materials And Methods: This non-interventional, multicentre, prospective, single-arm 24-week study documented PwT2D with an HbA1c of 7.5%-10.

Diabetes mellitus represents a significant and growing global health challenge, with its prevalence steadily increasing. Insulin therapy remains a cornerstone of diabetes management. Since its discovery in 1921, insulin has undergone substantial advancements, evolving from crude animal extracts to highly refined recombinant formulations and biosimilars.

Characterizing and mitigating factors that impact product immunogenicity can aid in risk assessment and/or managing risk following manufacturing changes. For follow-on products that have the same indication, patient population, and active product ingredient, the residual immunogenicity risk resides predominantly on differences in product and process related impurities. Characterizing differences in innate immune modulating impurities (IIRMI), which could act as adjuvants by activating local antigen presenting cells (APCs), can inform the immunogenicity risk assessment potentially reducing the need for clinical trials.

Introduction: ONWARDS 5 evaluated the effectiveness and safety of insulin icodec (icodec) titrated with a dosing guide app (icodec with app) versus once-daily insulin analogs in insulin-naive adults with type 2 diabetes. The insulin glargine U300 (glargine U300) stratum was too small to enable a robust post hoc efficacy comparison. Augmentation methodology was applied to increase the glargine U300 group size using real-world data (RWD), to facilitate efficacy comparisons of icodec with app versus glargine U300, and to demonstrate the potential of the augmentation methodology to strengthen underpowered treatment comparisons (AUGMENT study).
