Early-Onset Type 2 Diabetes and Tirzepatide Treatment: A Post Hoc Analysis From the SURPASS Clinical Trial Program.

OBJECTIVE: We evaluated baseline characteristics of participants with early-onset type 2 diabetes (T2D) from the SURPASS program and tirzepatide's effects on glycemic control, body weight (BW), and cardiometabolic markers. RESEARCH DESIGN AND METHODS: This post hoc analysis compared baseline characteristics and changes in mean HbA1c, BW, waist circumference (WC), lipids, and blood pressure (BP) in 3,792 participants with early-onset versus later-onset T2D at week 40 (A Study of Tirzepatide [LY3298176] in Participants With Type 2 Diabetes Not Controlled With Diet and Exercise Alone [SURPASS-1] and A Study of Tirzepatide [LY3298176] Versus Semaglutide Once Weekly as Add-on Therapy to Metformin in Participants With Type 2 Diabetes [SURPASS-2]) or week 52 (A Study of Tirzepatide [LY3298176] Versus Insulin Degludec in Participants With Type 2 Diabetes [SURPASS-3]). Analyses were performed by study on data from participants while on assigned treatment without rescue medication in case of persistent hyperglycemia. RESULTS: At baseline in SURPASS-2, participants with early-onset versus later-onset T2D were younger with longer diabetes duration (9 vs. 7 years, P < 0.001) higher glycemic levels (8.5% vs. 8.2%, P < 0.001), higher BW (97 vs. 93 kg, P < 0.001) and BMI (35 vs. 34 kg/m2, P < 0.001), and a similarly abnormal lipid profile (e.g., triglycerides 167 vs. 156 mg/dL). At week 40, similar improvements in HbA1c (-2.6% vs. -2.4%), BW (-14 vs. -13 kg), WC (-10 vs. -10 cm), triglycerides (-26% vs. -24%), HDL (7% vs. 7%), and systolic BP (-6 vs. -7 mmHg) were observed in both subgroups with tirzepatide. CONCLUSIONS: Despite younger age, participants with early-onset T2D from the SURPASS program had higher glycemic levels and worse overall metabolic health at baseline versus those with later-onset T2D. In this post hoc analysis, similar improvements in HbA1c, BW, and cardiometabolic markers were observed with tirzepatide, irrespective of age at T2D diagnosis. Future studies are needed to determine long-term outcomes of tirzepatide in early-onset T2D.

Effects of Tirzepatide Versus Basal Insulins in People With Type 2 Diabetes and Different Baseline Glycemic Patterns: Post Hoc Analyses of the SURPASS-3 and SURPASS-4 Trials.

OBJECTIVE: This post hoc analysis assessed change from baseline to week 52 in glycemic parameters for tirzepatide (5, 10, 15 mg) versus insulin degludec (SURPASS-3 trial) and glargine (SURPASS-4 trial) in people with type 2 diabetes and different baseline glycemic patterns, based on fasting serum glucose (FSG) and postprandial glucose (PPG) values. RESEARCH DESIGN AND METHODS: Participant subgroups with low FSG/low PPG, low FSG/high PPG, high FSG/low PPG, and high FSG/high PPG were defined according to the median values of these measures. RESULTS: All tirzepatide doses and basal insulins were associated with decreased HbA1c, FSG, and PPG values from baseline to week 52 in all subgroups (P < 0.05). Within each subgroup, HbA1c and PPG decreases were greater with tirzepatide than insulin (P < 0.05). FSG decreases were generally similar. There were no differential treatment effects by FSG/PPG subgroup. CONCLUSIONS: In this post hoc analysis, tirzepatide was associated with superior glycemic control compared with insulin, irrespective of baseline glycemic pattern.

Costes directos sanitarios y resultados clínicos tras el inicio del tratamiento con insulina en pacientes con diabetes mellitus tipo 2 en España: datos de 24 meses de seguimiento del estudio INSTIGATE / Direct healthcare costs and clinical outcomes after insulin initiation in patients with type 2 diabetes mellitus in Spain: 24–month follow-up data from the INSTIGATE study

Antecedentes y objetivoEl estudio INSTIGATE evalúa los costes directos sanitarios y los resultados clínicos en pacientes con diabetes mellitus tipo 2 que inician insulinoterapia en España, durante 24 meses.Material y métodoEstudio observacional, no intervencionista, prospectivo y multicéntrico. En cada visita se evaluaron los costes incurridos durante los 6 meses previos.ResultadosEn total se evaluaron 172 pacientes durante al menos 12 o un máximo de 24 meses con un índice de masa corporal medio de 29,6kg/m2, una duración media [desviación estándar] de la enfermedad de 10,9 [7,0] años y un porcentaje de hemoglobina A1c de 9,2% [1,5%]. Un total de 116 pacientes (67,4%) iniciaron insulina de acción prolongada/intermedia solamente. Los cambios medios intraindividuales en los valores iniciales de hemoglobina A1c tras 6, 12 y 24 meses de la insulinoterapia fueron, respectivamente, -1,9 [1,65%], -1,6 [1,73%] y -1,5% [1,76%]. La media (mediana) del total de los costes directos sanitarios por paciente aumentó de 659€ (527€) a 1.085€ (694€) 6 meses después del inicio de la insulinoterapia, bajó a 646€ (531€) después de 12 meses, y 24 meses después aumentó nuevamente a 667€ (539€). A los 24 meses, los costes de insulina/antidiabéticos orales, medicina general/especializada, y monitorización de la glucemia representaron el 41, 26 y 19%, respectivamente, de los costes totales.ConclusionesLos parámetros clínicos de estos pacientes con diabetes mellitus tipo 2 mejoraron tras iniciar la insulinoterapia. Tras un incremento temporal, los costes directos sanitarios del tratamiento de la diabetes volvieron a los valores basales al final del período de seguimiento (AU)

Background and objectiveThe INSTIGATE study assessed healthcare costs and clinical outcomes in patients with type 2 diabetes mellitus starting insulin therapy in Spain over a 24-month follow up period.Material and methodsThis was an observational, non-interventional, prospective, multicenter study. Costs incurred in the previous 6 months were assessed at each visit.ResultsA total of 172 patients with a mean body mass index of 29.6kg/m2, a mean [standard deviation] duration of diabetes of 10.9 [7.0] years and a hemoglobin A1c value of 9.2% [1.5%] were followed up for at least 12 and up to 24 months. Direct costs were assessed from the perspective of the Spanish healthcare system. Long/intermediate-acting insulin alone was started in 116 patients (67.4%). After 6, 12, and 24 months of insulin treatment, mean [SD] intraindividual changes from baseline in hemoglobin A1c were -1.9% [1.65%], -1.6 [1.73%], and -1.5% [1.76%] respectively. Mean (median) total diabetes-related healthcare costs per patient increased from €659 (€527) to €1.085 (€694) 6 months after insulin initiation, decreased to €646 (€531) after 12 months, and increased again after 24 months to €667(€539). Insulin/oral antidiabetics, primary/specialized care, and blood glucose monitoring accounted for 41%, 26%, and 19% of total cost at 24 months respectively.ConclusionsClinical parameters of these patients with type 2 diabetes mellitus improved following insulin initiation. After a temporary increase, direct healthcare costs of diabetes care returned to baseline values at the end of the follow-up period (AU)
