Importance The effect of continued treatment with tirzepatide on maintaining initial weight reduction is unknown. Objective To assess the tirzepatide, diet and physical activity, maintenance reduction. Design, Setting, Participants This phase 3, randomized withdrawal clinical trial conducted at 70 sites in 4 countries a 36-week, open-label lead-in period followed by 52-week, double-blind, placebo-controlled included adults body mass index greater than or equal to 30 27 weight-related...

Abstract In the SELECT cardiovascular outcomes trial, semaglutide showed a 20% reduction in major adverse events 17,604 adults with preexisting disease, overweight or obesity, without diabetes. Here this prespecified analysis, we examined effects of on weight and anthropometric outcomes, safety tolerability by baseline body mass index (BMI). patients treated semaglutide, loss continued over 65 weeks was sustained for up to 4 years. At 208 weeks, associated mean (−10.2%), waist circumference...

Summary The rate of weight reduction during obesity treatment declines over time and eventually reaches a plateau. We investigated factors associated with to plateau (TTWP) in tirzepatide‐treated participants or overweight post‐hoc analysis SURMOUNT‐1 SURMOUNT‐4 trials. Participants adherent tirzepatide achieving ≥5% loss by primary endpoint (week 72 SURMOUNT‐1; week 88 SURMOUNT‐4) were included. Weight was defined as change <5% 12‐week interval all subsequent intervals. TTWP from...

To determine the relationship between exposure and weight-loss trajectories for glucagon-like peptide-1 analogue semaglutide weight management.Data from one 52-week, phase 2, dose-ranging trial (once-daily subcutaneous 0.05-0.4 mg) two 68-week 3 trials (once-weekly 2.4 management in people with overweight or obesity without type 2 diabetes were used to develop a population pharmacokinetic (PK) model describing exposure. An exposure-response change was then developed using baseline...

Objective This study aimed to explore the relationship between an obesity diagnosis and weight loss as a percentage of total body over 9 15 months, using electronic health record data. Methods An observational 688,878 adult patients at systems with BMI ≥ 30 kg/m 2 examined documentation diagnosis. Multivariable logistic regression models were created stepwise backwards elimination procedure identify potential predictors loss.

Summary Despite the availability of a growing range interventions to assist control body weight for people with excess or obesity, only small proportion achieve their loss goals and are able maintain reductions in long term. Negative attitudes beliefs often found among physicians others involved treating obesity may adversely impact effectiveness management. In this international study, healthcare professionals were invited complete an online survey practice management weight. A total 335...

Despite the advice clinicians have been giving patients about importance of restricting their food intake and increasing physical activity levels, Centers for Disease Control Prevention (CDC) states that 78.6 million adults in United States (US) are still obese. With these statistics mind, this symposium provided insights on genetic, cultural, environmental underpinning obesity discussed latest research pharmacotherapy, surgery, need to individualize treatment.
