Objective: In SURMOUNT-4, participants with obesity or overweight regained substantial weight after tirzepatide withdrawal, whereas continued treatment resulted in additional weight reduction. We evaluated the effect of continued tirzepatide treatment on health-related quality of life (HRQoL) in SURMOUNT-4.

Methods: Participants who achieved tirzepatide maximum tolerated dose (MTD; 10 or 15 mg; N = 670) during a 36-week (W) lead-in period were randomized (1:1) to continue receiving tirzepatide MTD or switch to placebo through W88.

Aims: The objective was to assess weight reduction at Weeks 24 and 72 in participants treated with tirzepatide based on weight reduction response after 12 weeks of treatment in the SURMOUNT-1 trial.

Materials And Methods: This post hoc analysis included participants treated with tirzepatide who received ≥75% of the assigned treatment doses and had weight measurements at Weeks 0, 12, 24 and 72. Participants were categorized based on the 12-week response to tirzepatide: late responders (<5% weight reduction at Week 12) or early responders (≥5% weight reduction at Week 12).

The rate of weight reduction during obesity treatment declines over time and eventually reaches a weight plateau. We investigated factors associated with time to weight plateau (TTWP) in tirzepatide-treated participants with obesity or overweight in a post-hoc analysis of SURMOUNT-1 and SURMOUNT-4 trials. Participants adherent to tirzepatide treatment and achieving ≥5% weight loss by primary endpoint (week 72 SURMOUNT-1; week 88 SURMOUNT-4) were included.

Article Synopsis
  • The SURMOUNT-1 trial studied the effects of tirzepatide, a medication targeting obesity, on the health-related quality of life (HRQoL) of participants.
  • Participants reported significant improvements in physical function, psychosocial well-being, and overall health, with greater benefits observed in those achieving higher weight reductions.
  • Results highlighted that individuals with initial physical or psychosocial limitations experienced even more pronounced improvements in their health-related quality of life.

Introduction: Many patients with type 2 diabetes mellitus (T2DM) delay initiation of insulin therapy despite healthcare professional (HCP) advice. This phenomenon has been referred to as 'psychological insulin resistance' (PIR), and various contributing factors have been identified. Studies discussing approaches to overcoming PIR are lacking.

This study evaluated glucose control by continuous glucose monitoring (CGM) during treatment with ultra-rapid lispro (URLi) or lispro used in combination with insulin glargine or degludec in adults with type 1 diabetes in a substudy of the PRONTO-T1D study. Ambulatory glucose profiles were evaluated in 269 patients from PRONTO-T1D assigned to double-blind URLi ( = 97) or lispro ( = 99) given 0-2 min before the start of the meal (mealtime), or open-label URLi ( = 73) given 20 min after the meal (postmeal URLi). Blinded CGM was used for up to 14 days before baseline and the 26-week primary endpoint.

Objective: To understand participant perceptions about insulin and identify key behaviors of healthcare professionals (HCPs) that motivated initially reluctant adults from seven countries (n=40) who had type 2 diabetes (T2D) to start insulin treatment.

Research Design And Methods: Telephone interviews were conducted with a subset of participants from an international investigation of adults with T2D who were reluctant to start insulin (EMOTION). Questions related to: (a) participants' thoughts about insulin before and after initiation; (b) reasons behind responses on the survey that were either 'not helpful at all' or 'helped a lot'; (c) actions their HCP may have taken to help start insulin treatment; and (d) advice they would give to others in a similar situation of starting insulin.

Objective: Real-world effectiveness of basal insulin therapy is affected by poor treatment persistence, often occurring soon after initiation. This analysis is part of an international cross-sectional study conducted in T2DM patients and is intended to describe the reasons behind non-persistence to insulin therapy in Brasil.

Methods: Responders to an online survey in seven countries were classified as continuers (no gap of ≥7 days), interrupters (interrupted therapy for ≥7 days within first 6 months, then restarted), and discontinuers (terminated therapy for ≥7 days within first 6 months, and did not start it again before the survey).
