  9. Mean Change From Baseline in Short-Form-36 Health Survey Version 2 (SF-36v2) Acute Form Physical Functioning Domain Score

    The SF-36v2 acute form, 1-week recall assesses participants' health-related quality of life (HRQoL) on 8 domains: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health. Information from these 8 domains is further aggregated into 2 health component summary scores: Physical Component Summary and Mental Component Summary.

    Items are answered on Likert scales of varying lengths. Scoring of each domain and both summary scores are norm based and presented in the form of T scores, with a mean of 50 and standard deviation of 10; higher scores indicate better levels of function and/or better health. Range cannot be specified in norm-based scores.

    LS mean was determined using analysis of covariance (ANCOVA) model using Baseline + Sex + Presence of comorbidities + Treatment (Type III sum of squares) as variables.

    Measured: Baseline, Week 52

  10. Mean Change From Baseline in Impact of Weight on Quality of Life-Lite Clinical Trials Version (IWQOL-Lite-CT) Physical Function Composite Score

    The IWQOL Lite-CT consists of 20 items, assessing 2 primary domains of obesity related HRQoL: Physical (7 items) and Psychosocial (13 items). A 5-item subset of the Physical domain - the Physical Function composite - is also supported. Items in the Physical Function composite describe physical impacts related to general and specific physical activities. Total score of IWQOL-Lite-CT composite ranges from 0 to 100, with higher scores reflecting better quality of life. LS mean was determined using ANCOVA model with Baseline + Sex + Presence of comorbidities + Treatment (Type III sum of squares) as variables.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Tirzepatide in people with Obesity and Overweight, run by Eli Lilly and Company at 29 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 29 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Jan 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Percent Change From Baseline in Body Weight (time frame: Baseline, Week 52). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05024032, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2024.
