Insulin detemir offers improved glycemic control compared with NPH insulin in people with type 1 diabetes - A randomized clinical trial

OBJECTIVE—Insulin detemir is a soluble long-acting basal insulin analog designed to overcome the limitations of conventional basal insulin formulations. Accordingly, insulin detemir has been compared with NPH insulin with respect to glycemic control (HbA1c, prebreakfast glucose levels and variability, and hypoglycemia) and timing of administration. RESEARCH DESIGN AND METHODS—People with type 1 diabetes (n = 408) were randomized in an open-label, parallel-group trial of 16-week treatment duration using either insulin detemir or NPH insulin. Insulin detemir was administered twice daily using two different regimens, either before breakfast and at bedtime (IDetmorn+bed) or at a 12-h interval (IDet12h). NPH insulin was administered before breakfast and at bedtime. Mealtime insulin was given as the rapid-acting insulin analog insulin aspart. RESULTS—With both insulin detemir groups, clinic fasting plasma glucose was lower than with NPH insulin (IDet12h vs. NPH, −1.5 mmol/l [95% CI −2.51 to −0.48], P = 0.004; IDetmorn+bed vs. NPH, −2.3 mmol/l (−3.32 to −1.29), P < 0.001), as was self-measured prebreakfast plasma glucose (P = 0.006 and P = 0.004, respectively). The risk of minor hypoglycemia was lower in both insulin detemir groups (25%, P = 0.046; 32%, P = 0.002; respectively) compared with NPH insulin in the last 12 weeks of treatment, this being mainly attributable to a 53% reduction in nocturnal hypoglycemia in the IDetmorn+bed group (P < 0.001). Although HbA1c for each insulin detemir group was not different from the NPH group, HbA1c for the pooled insulin detemir groups was significantly lower than for the NPH group (mean difference −0.18% [−0.34 to −0.02], P = 0.027). Within-person between-day variation in self-measured prebreakfast plasma glucose was lower for both detemir groups (both P < 0.001). The NPH group gained weight during the study, but there was no change in weight in either of the insulin detemir groups (IDet12h vs. NPH, −0.8 kg [−1.44 to −0.24], P = 0.006; IDetmorn+bed vs. NPH, −0.6 kg [−1.23 to −0.03], P = 0.040). CONCLUSIONS—Overall glycemic control with insulin detemir was improved compared with NPH insulin. The data provide a basis for tailoring the timing of administration of insulin detemir to the individual person’s needs

Insulin detemir is associated with more predictable glycemic control and reduced risk of hypoglycemia than NPH insulin in patients with type 1 diabetes on a basal-bolus regimen with premeal insulin aspart

WSTĘP. Insulina detemir jest rozpuszczalnym, długodziałającym analogiem insuliny. Cechuje się wyjątkowym, wydłużonym profilem działania, pozwalającym na zmniejszenie zmienności glikemii, związanej ze stosowaniem konwencjonalnych insulin długodziałających. W badaniu porównano insulinę detemir i insulinę NPH pod względem uzyskanej kontroli glikemii, ryzyka hipoglikemii oraz wpływu na masę ciała u chorych na cukrzycę typu 1, otrzymujących przedposiłkowe wstrzyknięcia insuliny krótkodziałającej aspart. MATERIAŁ I METODY. Do badania zakwalifikowano metodą randomizacji 448 chorych na cukrzycę typu 1, którym podawano insulinę detemir lub NPH w stosunku 2:1. Badanie typu otwartego, w którym porównywano równolegle obie grupy pacjentów, trwało 6 miesięcy i było prowadzone w 46 ośrodkach, w 5 krajach. WYNIKI. Po 6 miesiącach badania wartości hemoglobiny glikowanej (HbA1c) w obu grupach były porównywalne. Glikemia na czczo była nieco niższa u chorych leczonych insuliną detemir, jednak różnica ta nie była istotna statystycznie (&#8211;0,76 mmol/l; p = 0,097). Zmienność glikemii na czczo określana na podstawie samokontroli u poszczególnych pacjentów była mniejsza przy stosowaniu insuliny detemir niż insuliny NPH (SD 3,37 vs. 3,78 mmol/l; p < 0,001). Ryzyko niedocukrzenia było o 22% niższe w grupie leczonej insuliną detemir niż w grupie przyjmującej insulinę NPH (p < 0,05); a ryzyko nocnych niedocukrzeń (23.00-06.00) &#8212; o 34% niższe (p < 0,005). Profil glikemii w porze nocnej był bardziej stabilny i stały podczas stosowania insuliny detemir (p = 0,05). Na końcu badania u pacjentów leczonych insuliną detemir zaobserwowano istotnie niższą masę ciała (p < 0,001). WNIOSKI. Leczenie insuliną detemir wiąże się z bardziej przewidywalną kontrolą glikemii, z mniejszymi wahaniami glikemii w ciągu doby oraz istotnym zmniejszeniem ryzyka niedocukrzeń w porównaniu ze stosowaniem insuliny NPH. Zmniejszenie masy ciała podczas terapii insuliną detemir jest dodatkowym, potencjalnie korzystnym efektem. Schematy leczenia oparte na insulinie detemir mogą umożliwić lepszą kontrolę glikemii niż schematy oparte na insulinie NPH.INTRODUCTION. Insulin detemir is a soluble basal insulin analog with a unique mechanism of protracted action designed to reduce the variability associated with conventional basal insulins. This trial compared the glycemic control, risk of hypoglycemia, and effect on body weight of insulin detemir and NPH insulin in patients with type 1 diabetes treated with rapid-acting insulin aspart at meals. MATERIAL AND METHODS. This study was a 6-month multinational open parallel-group comparison conducted at 46 centers in five countries and included 448 patients with type 1 diabetes randomized 2:1 to insulin detemir or NPH insulin, respectively. RESULTS. After 6 months, comparable HbA1c levels were found between the two treatment groups. Fasting plasma glucose tended to be lower in patients treated with insulin detemir, but this difference was not statistically significant (&#8211;0.76 mmol/l, P = 0.097). Within-subject variation in self-measured fasting blood glucose was lower with insulin detemir than with NPH insulin (SD 3.37 vs. 3.78 mmol/l, P < 0.001). Risk of hypoglycemia was 22% lower with insulin detemir than with NPH insulin (P < 0.05) and 34% lower for nocturnal (2300&#8211;0600) hypoglycemia (P < 0.005). Nightly plasma glucose profiles were smoother and more stable with insulin detemir (P < 0.05). Body weight was significantly lower with insulin detemir at the end of the trial (P < 0.001). CONCLUSIONS. Treatment with insulin detemir resulted in more predictable glycemic control, with smoother plasma glucose profiles than NPH insulin and a significant reduction in the risk of hypoglycemia. The reduction in body weight with insulin detemir is a potential additional advantage. Regimens optimized for insulin detemir may be able to improve glycemic control beyond that possible with NPH insulin

CVOT Summit 2022 Report : new cardiovascular, kidney, and glycemic outcomes

The 8th Cardiovascular Outcome Trial (CVOT) Summit on Cardiovascular, Kidney, and Glycemic Outcomes was held virtually on November 10-12, 2022. Following the tradition of previous summits, this reference congress served as a platform for in-depth discussion and exchange on recently completed outcomes trials as well as key trials important to the cardiovascular (CV) field. This year's focus was on the results of the DELIVER, EMPA-KIDNEY and SURMOUNT-1 trials and their implications for the treatment of heart failure (HF) and chronic kidney disease (CKD) with sodiumglucose cotransporter-2 (SGLT2) inhibitors and obesity with glucose- dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonists. A broad audience of primary care physicians, diabetologists, endocrinologists, cardiologists, and nephrologists participated online in discussions on new consensus recommendations and guideline updates on type 2 diabetes ( T2D) and CKD management, overcoming clinical inertia, glycemic markers, continuous glucose monitoring (CGM), novel insulin preparations, combination therapy, and reclassification of T2D. The impact of cardiovascular outcomes on the design of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) trials, as well as the impact of real-world evidence (RWE) studies on the confirmation of CVOT outcomes and clinical trial design, were also intensively discussed. The 9th Cardiovascular Outcome Trial Summit will be held virtually on November 23-24, 2023 (http://www.cvot.org).Peer reviewe
