Trial Outcomes & Findings for A Drug-Drug Interaction Study Between PF-06882961 and PF-06865571 in Healthy Adult Participants and Overweight Adults or Adults With Obesity Who Are Otherwise Healthy (NCT NCT04839393)

NCT ID: NCT04839393

Last Updated: 2023-08-21

Results Overview

AUCinf for PF-06865571 was calculated as AUClast + (Clast\*/kel) on Day 1 and Day 47. Clast\* was the predicted plasma concentration at the last quantifiable time point estimated from the log-linear regression analysis and kel was the elimination rate constant.

SECONDARY outcome

Timeframe: Up to 68 days

Population: The safety analysis set included all participants randomly assigned to investigational product and who took at least 1 dose of study intervention.

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Any AEs occurring following start of study intervention were counted as treatment emergent. Serious AEs (SAEs) were defined as any untoward medical occurrence at any dose that resulted in death; was life-threatening (immediate risk of death); required inpatient hospitalization or caused prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity (substantial disruption of the ability to conduction normal life functions). AEs included SAEs and non-serious AEs. Relatedness to study treatment was determined by the investigator.

Population: The analysis set included all participants assigned to study intervention and who took at least 1 dose of study intervention. Participants with evaluable C-SSRS results were analyzed.

The C-SSRS was an interview-based rating scale to systematically assess suicidal ideation and suicidal behavior. C-SSRS assessed whether participant experienced any of the following 1: completed suicide, 2: suicide attempt (response of "yes" on "actual attempt"), 3: preparatory acts toward imminent suicidal behavior ("yes" on "aborted attempt", "interrupted attempt", "preparatory acts or behavior"), 4: any suicidal behavior or ideation, suicidal ideation ("yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent"), 7: self-injurious behavior, no suicidal intent ("yes" on "has participant engaged in non-suicidal self-injurious behavior").

Population: The analysis set included all participants assigned to study intervention and who took at least 1 dose of study intervention. Participants with evaluable PHQ-9 results were analyzed.

The PHQ-9 is a 9 item self-report scale for the assessment of depressive symptoms. The questions included "little interest/pleasure in things", "feeling down depressed or hopeless", "trouble falling or staying asleep", "feeling tired or little energy", "poor appetite or overeating", "feeling bad about yourself", "trouble concentrating on things", "moving slowly or fidgety/restless" and "thoughts you be better off dead". Each item was scored on scale of "not at all", "several days", "more than half the days" to "nearly every day". Total score range: 0-27 (each item with scale from 0 \[not at all\] to 3 \[nearly every day\]. Higher score=greater severity). Any participant with a response of any scale other than "not at all" to any of the 9 questions was counted.
