Abstract Disclaimer In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose This study evaluated the stability of diluted insulin aspart solutions (containing insulin aspart and preservatives) at their most commonly used concentration in intensive care units (1 unit/mL), in 2 container types: cyclic olefin copolymer (COC) vials and polypropylene (PP) syringes. Methods Insulin aspart solution (1 unit/mL, diluted in 0.9% sodium chloride injection) was stored for 365 days in COC vials with gray stoppers and PP syringes at refrigerated (5±3°C) and ambient temperatures (25°C ± 2°C at 60% ± 5% relative humidity and protected from light). Chemical testing was conducted monthly using a validated high-performance liquid chromatography method (quantification of insulin aspart, phenol, and metacresol). Physical stability was evaluated monthly via pH measurements, visible and subvisible particle counts, and osmolality measurements. Sterility testing was also performed to validate the sterile preparation process and the maintenance of sterility throughout the study. Results The limit of stability was set at 90% of the initial concentrations of insulin aspart, phenol, and metacresol. The physicochemical stability of 1-unit/mL insulin solutions stored refrigerated and protected from light, was unchanged in COC vials for the 365-day period and for 1 month in PP syringes. At ambient temperature, subvisible particulate contamination as well as the chemical stability of insulin and metacresol were acceptable for only 1 month’s storage in PP syringes, while insulin chemical stability was maintained for only 3 months’ storage in COC vials. Conclusion According to our results, it is not recommended to administer 1-unit/mL pharmacy-diluted insulin solutions after 3 months’ storage in COC vials at ambient temperature or after 1 month in PP syringes at ambient temperature. The findings support storage of 1-unit/mL insulin aspart solution in COC vials at refrigerated temperature as the best option over the long term. Sterility was maintained in every condition. Both sterility and physicochemical stability are essential to authorize the administration of a parenteral insulin solution.

This post-authorization study was conducted to evaluate the safety of insulin degludec/insulin aspart (IDegAsp) in adult patients with diabetes mellitus (DM) during routine clinical care under a real-world setting in India. Eligible patients received IDegAsp for a minimum of 12 months during routine clinical management. Data were collected at 0, 3, 6, and 12 months. In total, 1029 adult patients with DM were included; 65.2% (n = 671) were men; mean age was 55.0 ± 12.2 years, and the mean duration of diabetes mellitus was 10.8 ± 7.4 years. Thirty adverse events were reported in 23 patients (2.2%) during the follow-up: two adverse events in two patients were serious with fatal outcomes, which were unrelated to IDegAsp use. At baseline, there were 176 confirmed hypoglycemic events in 67 (6.7%) patients while they were on their previous treatment options. At 12 months of treatment with IDegAsp, 11 confirmed hypoglycemic events were reported in 11 (1.1%) patients since the previous visit; there were no reported episodes of severe hypoglycemia. Mean glycosylated hemoglobin value reduced from 9.5% ± 1.8% at baseline to 7.7% ± 1.1% at 12 months. This study showed the safety of IDegAsp in patients with diabetes mellitus over a period of 1 year during routine clinical care.

AbstractThis study compared the pharmacokinetic and glucodynamic profiles of biosimilar SAR341402 insulin aspart to Japan-approved insulin aspart (NovoRapid) in healthy Japanese males. In this single-center, randomized, double-blind, single-dose, two-period, crossover study, subjects received 0.3 U/kg of SAR341402 or NovoRapid before undergoing a 10 h euglycemic clamp procedure. Plasma insulin aspart concentrations and blood glucose levels were measured, and glucose infusion rates (GIRs) were assessed. Primary endpoints were maximum plasma insulin aspart concentration (INS-Cmax), area under the plasma insulin concentration–time curve to the last quantifiable concentration (INS-AUClast), area under the GIR–time curve during the clamp (GIR-AUC0–10 h), and maximum GIR (GIRmax). Forty subjects were randomized with 39 completing both treatment periods. Pharmacokinetic exposure showed a mean ratio between products of 1.00 (90% confidence interval [CI] 0.94–1.05) for INS-Cmax and 1.02 (90% CI 1.00–1.04) for INS-AUClast. Glucodynamic activity showed a mean ratio between products of 1.00 (95% CI 0.93–1.06) for GIR-AUC0–10 h and 1.01 (95% CI 0.95–1.08) for GIRmax. The 90% CIs for pairwise treatment ratios were within the predefined equivalence range of 0.80–1.25. Both treatments were well tolerated. We concluded that similar pharmacokinetic exposure and glucodynamic potency were shown for SAR341402 and NovoRapid in healthy Japanese males.
