Patient-Reported Outcomes in People with Type 2 Diabetes Receiving Tirzepatide in the SURPASS Clinical Trial Programme.

ABSTRACT:

Introduction

Tirzepatide, a novel glucose-dependent insulinotropic polypeptide and glucagon-like peptide 1 receptor agonist, is approved for glycaemic control for people with type 2 diabetes (T2D). The SURPASS-1 to -5 clinical trials assessed the efficacy of once weekly tirzepatide (5, 10 and 15 mg) versus placebo or active comparators (semaglutide 1 mg, insulin degludec and insulin glargine) in T2D. We evaluated patient-reported outcomes (PROs) that measured overall quality of life (QoL), treatment satisfaction and weight-related attributes across the five SURPASS studies.

Methods

PRO instruments utilised at baseline and primary timepoint (40 weeks for SURPASS-1, -2 and -5; 52 weeks for SURPASS-3 and -4) or early termination visit were EQ-5D-5L (SURPASS-1 to -5); Impact of Weight on Self-Perceptions (SURPASS-1 to -5); Ability to Perform Physical Activities of Daily Living (SURPASS-1 to -5); Diabetes Treatment Satisfaction Questionnaire (SURPASS-2 to -5); and Impact of Weight on Quality of Life-Lite Clinical Trials Version (SURPASS-2 only).

Results

Across all five studies at week 40/52, tirzepatide improved patients' QoL measured by general health and weight-related PROs over the comparator. Generally, higher doses of tirzepatide resulted in greater increases in PRO scores.

Conclusion

Overall, tirzepatide produced significant health and weight-related QoL improvements versus comparators in the five SURPASS studies.

Project description:BackgroundTirzepatide, a once-weekly glucose-dependent insulinotropic polypeptide/ glucagon-like peptide-1 receptor agonist, is approved in the United States, Europe and Japan for the treatment of type 2 diabetes. Across the SURPASS-1 to -5 clinical studies, tirzepatide 5, 10 and 15 mg demonstrated significant improvements in glycated haemoglobin A1c (HbA1c) (- 1.9 to - 2.6%), body weight (- 6.6 to - 13.9%) and systolic blood pressure (SBP) (- 2.8 to - 12.6 mmHg) at the end of study treatment.MethodsPost-hoc mediation analyses were conducted to evaluate weight-loss dependent and weight-loss independent effects of tirzepatide on SBP reductions across the 5 SURPASS studies. The safety population (all randomized patients who took at least 1 dose of study drug) of each study was analyzed. Additional analyses were conducted at individual study level or pooled across 5 SURPASS trials.ResultsThe difference in mean SBP change from baseline at 40 weeks (total effect) between the tirzepatide and comparator groups was - 1.3 to - 5.1 mmHg (tirzepatide 5 mg), - 1.7 to - 6.5 mmHg (tirzepatide 10 mg) and - 3.1 to - 11.5 mmHg (tirzepatide 15 mg). These SBP reductions were primarily mediated through weight loss, with different degrees of contributions from weight-loss independent effects across the different trials. In the SURPASS-4 study, which enrolled patients with established cardiovascular disease, weight-loss independent effects explained 33% to 57% of difference in SBP change between tirzepatide and insulin glargine groups. In a pooled analysis of the SURPASS-1 to -5 studies, there was a significant (p < 0.001) but weak correlation (r = 0.18 to 0.22) between change in body weight and SBP. Reductions in SBP with tirzepatide were not dependent on concomitant antihypertensive medications at baseline as similar reductions were observed whether participants were receiving them or not (interaction p = 0.77). The largest SBP reductions were observed in the highest baseline category (> 140 mmHg), while those in the first quartile of baseline SBP category (< 122 mmHg) observed no further decrease in SBP.ConclusionsTirzepatide-induced SBP reduction was primarily mediated through weight loss, with different degrees of contributions from weight-loss independent effects across the different trials. SBP reduction was not dependent on antihypertensive medication use but dependent on baseline SBP value, alleviating theoretical concerns of hypotension.

Project description:IntroductionTirzepatide, a once-weekly glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1 receptor agonist, provides clinically meaningful improvements in glycaemic control and body weight loss in people with type 2 diabetes. The early efficacy profile of tirzepatide after treatment initiation is of interest. In this exploratory pre-planned analysis, we evaluated the time to achieve glycaemic control and body weight loss thresholds with tirzepatide.MethodsIn two randomised studies, we compared time to achieve HbA1c (< 7.0% and ≤ 6.5%) and weight loss (≥ 5%, SURPASS-2 only) thresholds among people treated with tirzepatide (5, 10, and 15 mg), semaglutide 1 mg in SURPASS-2, and titrated insulin degludec in SURPASS-3. Longitudinal logistic regression models were used to explore the proportion of participants achieving HbA1c and body weight loss thresholds at 4, 12, and 24 weeks. The time to achieve these thresholds was analysed and compared between groups using the Cox proportional-hazards model.ResultsOverall, greater proportions of participants achieved the HbA1c and body weight loss thresholds at 4, 12, and 24 weeks with tirzepatide compared with semaglutide 1 mg and insulin degludec. The median time to achieve HbA1c < 7.0% (8.1 weeks with each tirzepatide dose, 12.0 weeks with semaglutide 1 mg, and 12.1 weeks with insulin degludec) and ≤ 6.5% (12.1, 15.7, and 24.1 weeks, respectively) was faster with tirzepatide than semaglutide 1 mg and insulin degludec. In SURPASS-2, the median time to first achieve a body weight loss of ≥ 5% was faster with tirzepatide 5 mg (16.0 weeks) and 10 and 15 mg (12.4 weeks) than with semaglutide 1 mg (24.0 weeks).ConclusionAnalyses of data from SURPASS-2 and -3 revealed that tirzepatide treatment enabled more people with type 2 diabetes to achieve glycaemic thresholds and these were achieved faster than with semaglutide 1 mg or insulin degludec. Tirzepatide-treated participants also achieved a body weight loss of ≥ 5% significantly faster with tirzepatide than with semaglutide 1 mg.Trial registration numbersNCT03987919; NCT03882970.

Project description:IntroductionThe presence of metabolic abnormalities in patients with type 2 diabetes (T2D) increases the risk of cardiovascular disease and other comorbidities. This analysis compared the effects of tirzepatide (5, 10, and 15 mg) and dulaglutide 0.75 mg on the prevalence of metabolic abnormalities in Japanese patients with T2D.MethodsThis was a post hoc analysis of SURPASS J-mono, a multicenter, randomized, double-blind, active-controlled, parallel-group, phase 3 trial that compared the efficacy and safety of tirzepatide monotherapy (5, 10, and 15 mg) to dulaglutide 0.75 mg in Japanese patients with T2D. Thresholds for abnormalities were based on the Japanese criteria for metabolic syndrome. Proportions of participants meeting a composite endpoint (visceral fat accumulation measured by waist circumference plus two or more of dyslipidemia, hypertension, or hyperglycemia) or individual component thresholds were calculated at baseline and week 52 for the overall population and for baseline body mass index (BMI) subgroups (< 25, 25 to < 30, and ≥ 30 kg/m2).ResultsOf 636 randomized participants, 431 (67.8%) met the composite endpoint at baseline, with similar findings observed across treatment arms. At week 52, the proportion of participants on treatment that met the composite endpoint was 31.7%, 23.0%, and 14.2% in the tirzepatide 5-, 10-, and 15-mg arms, respectively, and 56.5% in the dulaglutide arm (p < 0.001). A higher proportion met the composite endpoint at baseline in the BMI 25 to < 30 and ≥ 30 kg/m2 subgroups (73.2-79.3%) compared with the < 25 kg/m2 subgroup (45.3%), with reductions observed across all BMI subgroups treated with tirzepatide. The proportion of participants with individual metabolic abnormalities showed similar trends to those observed for the composite endpoint. Tirzepatide was consistently superior to dulaglutide across all assessments.ConclusionsTirzepatide reduced the prevalence of multiple metabolic abnormalities, indicating tirzepatide may have metabolic benefit in Japanese patients with T2D.Trial registrationClinicalTrials.gov, NCT03861052.

Project description:ImportanceThe effects of tirzepatide, a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, as an addition to insulin glargine for treatment of type 2 diabetes have not been described.ObjectiveTo assess the efficacy and safety of tirzepatide added to insulin glargine in patients with type 2 diabetes with inadequate glycemic control.Design, setting, and participantsRandomized phase 3 clinical trial conducted at 45 medical research centers and hospitals in 8 countries (enrollment from August 30, 2019, to March 20, 2020; follow-up completed January 13, 2021) in 475 adults with type 2 diabetes and inadequate glycemic control while treated with once-daily insulin glargine with or without metformin.InterventionsPatients were randomized in a 1:1:1:1 ratio to receive once-weekly subcutaneous injections of 5-mg (n = 116), 10-mg (n = 119), or 15-mg (n = 120) tirzepatide or volume-matched placebo (n = 120) over 40 weeks. Tirzepatide was initiated at 2.5 mg/week and escalated by 2.5 mg every 4 weeks until the assigned dose was achieved.Main outcomes and measuresThe primary end point was mean change from baseline in glycated hemoglobin A1c (HbA1c) at week 40. The 5 key secondary end points included mean change in body weight and percentage of patients achieving prespecified HbA1c levels.ResultsAmong 475 randomized participants (211 [44%] women; mean [SD] age, 60.6 [9.9] years; mean [SD] HbA1c, 8.31% [0.85%]), 451 (94.9%) completed the trial. Treatment was prematurely discontinued by 10% of participants in the 5-mg tirzepatide group, 12% in the 10-mg tirzepatide group, 18% in the 15-mg tirzepatide group, and 3% in the placebo group. At week 40, mean HbA1c change from baseline was -2.40% with 10-mg tirzepatide and -2.34% with 15-mg tirzepatide vs -0.86% with placebo (10 mg: difference vs placebo, -1.53% [97.5% CI, -1.80% to -1.27%]; 15 mg: difference vs placebo, -1.47% [97.5% CI, -1.75% to -1.20%]; P < .001 for both). Mean HbA1c change from baseline was -2.11% with 5-mg tirzepatide (difference vs placebo, -1.24% [95% CI, -1.48% to -1.01%]; P < .001]). Mean body weight change from baseline was -5.4 kg with 5-mg tirzepatide, -7.5 kg with 10-mg tirzepatide, -8.8 kg with 15-mg tirzepatide and 1.6 kg with placebo (5 mg: difference, -7.1 kg [95% CI, -8.7 to -5.4]; 10 mg: difference, -9.1 kg [95% CI, -10.7 to -7.5]; 15 mg: difference, -10.5 kg [95% CI, -12.1 to -8.8]; P < .001 for all). Higher percentages of patients treated with tirzepatide vs those treated with placebo had HbA1c less than 7% (85%-90% vs 34%; P < .001 for all). The most common treatment-emergent adverse events in the tirzepatide groups vs placebo group were diarrhea (12%-21% vs 10%) and nausea (13%-18% vs 3%).Conclusions and relevanceAmong patients with type 2 diabetes and inadequate glycemic control despite treatment with insulin glargine, the addition of subcutaneous tirzepatide, compared with placebo, to titrated insulin glargine resulted in statistically significant improvements in glycemic control after 40 weeks.Trial registrationClinicalTrials.gov Identifier: NCT04039503.

Project description:BackgroundThere is considerable evidence that repetitive negative thoughts are often associated with adverse health outcomes. The study aims are (i) to identify the frequency and valence of thoughts about health in people with diabetes mellitus using questions based on the day reconstruction method (DRM) and (ii) to analyse associations between thoughts about health and health-related quality of life (HRQoL), diabetes-related distress and depressive symptoms.MethodsCross-sectional study of a random sample of a German statutory health insurance population with diabetes aged between 18 and 80 linking questionnaire and claims data. Associations between frequency and valence of thoughts about health on a previous day and HRQoL assessed by a 12-Item Short-Form Health Survey, diabetes-related distress assessed using the Problem Areas in Diabetes scale and depressive symptoms assessed by Patient Health Questionnaire-9 were analysed using linear and logistic regression analysis, adjusting for sociodemographic and clinical characteristics.ResultsThoughts about health were analysed in 726 participants (86% type 2 diabetes, 62% male, mean age 67.6 ± 9.7 years). A total of 46% had not thought about their health the day before, 17.1% reported low frequency and negative thoughts, 21.4% low frequency and positive thoughts, 12.1% high frequency and negative thoughts and 3.4% high frequency and positive thoughts. The presence of thoughts about health irrespective of their frequency and valence is associated with a lower physical and mental component summary score of the 12-Item Short-Form Health Survey. Negative thoughts are associated with high diabetes-related distress. Frequent or negative thoughts are associated with depressive symptoms.ConclusionsThoughts about health are a part of everyday life for a substantial number of people with diabetes. Surprisingly, even positive thoughts are associated with poorer HRQoL in our study. Further research within the DRM paradigm is needed to understand how thoughts about health may affect people's (assessment of) state of health. Thoughts about health should be considered in diabetes education and patient counselling with a view to preventing and treating emotional disorders. More attention should be paid to the outcomes of interventions that may themselves lead to an increase in the frequency of thoughts about health.
