Trial Outcomes & Findings for A Study to Compare Two Different Forms of PF-07081532 in Adults Who Are Overweight or Obese (NCT NCT05677867)

NCT ID: NCT05677867

Last Updated: 2024-08-09

Results Overview

AUCinf is the area under the concentration-time curve to infinity. AUCinf was calculated by AUClast + (Clast\*/kel), where Clast\* is the predicted plasma concentration at the last quantifiable time point estimated from the log-linear regression analysis and kel is the terminal phase rate constant calculated by a linear regression of the log-linear concentration time curve.

Population: All participants who take at least 1 dose of study intervention.

An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious adverse event (SAE) was defined as an AE: 1. resulting in death, 2. was life-threatening, 3. required inpatient hospitalization or prolongation of existing hospitalization, 4. resulted in persistent disability, 5. was a congenital anomaly/birth defect, or considered to be an important medical event. Treatment-related AE was any untoward medical occurrence attributed to study intervention in a participant who received study intervention. Treatment-emergent are events between first dose of study intervention and up to 28-35 days after last dose that were absent before treatment or that worsened relative to pretreatment state.
