Post Hoc Analysis of SURPASS-1 to -5: Efficacy and Safety of Tirzepatide in Adults with Type 2 Diabetes are Independent of Baseline Characteristics.
Introduction: Newer incretin-based therapies for type 2 diabetes (T2D) have the potential to substantially reduce glycated hemoglobin (HbA1c) and weight with a low associated risk of hypoglycemia. This study aimed to assess the percentage of participants randomized to tirzepatide or comparator who achieved the composite endpoint of HbA1c ≤ 6.5% and weight reduction ≥ 10% without hypoglycemia across prespecified baseline characteristics: T2D duration (≤ 5, > 5-10, or > 10 years), sex, HbA1c (≤ 8.5% or > 8.5%), age (< 65 or ≥ 65 years), and body mass index (< 30, 30 to < 35, or ≥ 35 kg/m2).
Methods: This post hoc analysis of SURPASS-1 through -5 evaluated adult study participants with T2D treated with tirzepatide 5, 10, or 15 mg versus placebo or active comparator. Missing HbA1c and weight values were imputed from mixed models for repeated measures. Logistic regression was used to compare tirzepatide versus comparators for the percentage of participants reaching the composite endpoint.
Results: Across subgroups, the composite endpoint was achieved by a median of approximately 30%, 45%, and 54% of participants who received tirzepatide 5, 10, and 15 mg, respectively; this was consistent across baseline subgroups, except that a greater percentage of women than men achieved the composite endpoint. The most common treatment-emergent adverse events were gastrointestinal in nature.
Conclusions: In this post hoc analysis, tirzepatide achieved the composite outcome of glycemic control and weight loss with no hypoglycemia, irrespective of baseline characteristics. This may help clinicians as they select suitable treatment in diverse populations.
Trial registration: ClinicalTrials.gov: NCT03954834, NCT03987919, NCT03882970. NCT03730662, and NCT04039503.
期刊介绍：
Diabetes Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all areas of diabetes. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Diabetes Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
