Brief summary

Two different groups of healthy volunteers will be chronically treated with GLP-1 drugs PF-07081532 or alternatively Semaglutide. The effect of these GLP-1 drugs on a single dose of the common sedative medication midazolam blood levels will be measured. The effect of chronic PF-07081532 on single doses of the common stomach acid medication omeprazole, and common birth control medication blood levels will also be measured. The hypothesis is that chronic administration of the GLP-1 drugs will minimally affect blood levels from these common medications.

Interventions

DRUGSemaglutide

C-SSRS items were mapped to the following categories: completed suicide, suicide attempt, preparatory acts towards imminent suicidal behavior, suicidal ideation, and self-injurious behavior of no suicidal intent. Number of participants with completed suicide, suicide attempt, preparatory acts towards imminent suicidal behavior, suicidal ideation, or self-injurious behavior of no suicidal intent as assessed on the C-SSRS are reported below.

Cohort 1: Number of Participants With All-Causality and Treatment-Related TEAEs

An adverse event (AE) was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. Treatment-related AE was any untoward medical occurrence attributed to study treatment in a participant who received study treatment. Relatedness to study treatment was assessed by the investigator. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent events were events between first dose of study treatment and up to approximately 35 days that were absent before treatment or that worsened relative to pretreatment state.

Time frame: From first dose (Day 1) to follow-up telephone contact (Days 153 to 160) in Cohort 1

Population: All participants randomly assigned to study intervention and who took at least 1 dose of study intervention.

The PHQ-9 is a 9 item self-report scale for the assessment of depressive symptoms. The PHQ-9 is completed by participants and reviewed by site staff at the pre-defined time points. The total score is derived by adding the corresponding values of responses to each item. The total score ranges from 0 to 27, with the following interpretation: 1-4: Minimal depression; 5-9: Mild depression; 10-14: Moderate depression; 15-19: Moderately severe depression; 20-27: Severe depression.

Cohort 2: Number of Participants With All-Causality and Treatment-Related TEAEs

An adverse event (AE) was any untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. Treatment-related AE was any untoward medical occurrence attributed to study treatment in a participant who received study treatment. Relatedness to study treatment was assessed by the investigator. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent events were events between first dose of study treatment and up to approximately 35 days that were absent before treatment or that worsened relative to pretreatment state.

Time frame: From first dose (Day 1) to follow-up telephone contact (Days 193 to 200) in Cohort 2

Population: All participants randomly assigned to study intervention and who took at least 1 dose of study intervention.

Cohort 2: Number of Participants With Completed Suicide, Suicide Attempt, Preparatory Acts Towards Imminent Suicidal Behavior, Suicidal Ideation, or Self-Injurious Behavior of No Suicidal Intent As Assessed on the C-SSRS

The C-SSRS is an interview-based rating scale to systematically assess suicidal ideation and suicidal behavior. C-SSRS items were mapped to the following categories: completed suicide, suicide attempt, preparatory acts towards imminent suicidal behavior, suicidal ideation, and self-injurious behavior of no suicidal intent. Number of participants with completed suicide, suicide attempt, preparatory acts towards imminent suicidal behavior, suicidal ideation, or self-injurious behavior of no suicidal intent as assessed on the C-SSRS are reported below.

Time frame: Screening, D-1 (P1D-1), P2 Week 5 [W5], P2W9, P2W13, P2W17, D150 (P3D2), at follow up visit (Day 172-175)

Population: All participants randomly assigned to study intervention and who took at least 1 dose of study intervention. Participants with evaluable C-SSRS results were analyzed.

Cohort 2: PHQ-9 Total Scores

The PHQ-9 is a 9 item self-report scale for the assessment of depressive symptoms. The PHQ-9 is completed by participants and reviewed by site staff at the pre-defined time points. The total score is derived by adding the corresponding values of responses to each item. The total score ranges from 0 to 27, with the following interpretation: 1-4: Minimal depression; 5-9: Mild depression; 10-14: Moderate depression; 15-19: Moderately severe depression; 20-27: Severe depression.

Time frame: Screening, D-1 (P1D-1), P2 Week 5 [W5], P2W9, P2W13, P2W17, D150 (P3D2), at follow up visit (Day 172-175)

Population: All participants randomly assigned to study intervention and who took at least 1 dose of study intervention. Participants with evaluable PHQ-9 results were analyzed.

Cohort 2: t1/2 of Midazolam in Period 1 and 3

Midazolam was given on Day 1 in Period 1 and 3 of Cohort 2 and blood samples were collected for midazolam pharmacokinetic (PK) at the preset time points described in the Time Frame. t1/2 was defined as terminal half life and was calculated as loge(2)/kel.

Time frame: For Cohort 2 Periods 1 and 3: At 0 (prior to midazolam dose), 0.5, 1, 2, 3, 4, 6, 8, 10, 14, 24 hours post midazolam dose on Day 1 of each period
