AUCinf is area under the plasma concentration-time profile from time zero extrapolated to infinite time. AUCinf is caluculated by AUClast + (Clast/kel), where Clast is the predicted plasma concentration at the last quantifiable time point estimated from the log-linear regression analysis.

Urine and feces samples collected after a single oral dose of \[14C\]PF-07081532 30 mg (\~250 nCi) in Period 1 were analyzed using Accelerator Mass Spectrometry (AMS). "Blank" pre-dose urine samples were collected within the 24 hours prior to dosing, "blank" fecal samples were collected from at least 1 bowel movement within the 48 hours prior to dosing. Following oral dosing, each urine void was collected across intervals of 0-12 hours, 12-24 hours, and each subsequent 24 hour interval up to 360 hours post dose, and all feces excreted were collected across each 24 hour interval up to 360 hours post dose. Recovery of radioactivity in urine, feces, and both routes combined, determined as percentage of the orally administered radioactive dose, are reported.

Plasma samples collected after a single oral dose of \[14C\]PF-07081532 30 mg (\~250 nCi) were analyzed using Ultra Performance Liquid Chromatography coupled to High Resolution Mass Spectrometry (UPLC-HRMS). Relative abundance = (sum of radioactive content of fractions contributing to a particular peak/total circulating drug-related material \[total \[14C\] radioactivity in plasma\]) x 100%. Metabolites that were detected and identifiable (including coeluting metabolites reported together) are reported in this outcome measure (OM).

Urine and feces samples collected after a single oral dose of \[14C\]PF-07081532 30 mg (\~250 nCi) were analyzed using UPLC-HRMS. "Blank" pre-dose urine samples were collected within the 24 hours prior to dosing, "blank" fecal samples were collected from at least 1 bowel movement within the 48 hours prior to dosing. To obtain samples for evaluation of relative abundance in urine and feces, following oral dosing, each urine void was collected across intervals of 0-12 hours, 12-24 hours, and each subsequent 24 hour interval up to 96 hours post dose, and all feces excreted were collected across each 24 hour interval up to 144 hours post dose. Relative abundance was determined as sum of radioactive content of fractions contributing to a particular peak divided by total radioactive dose excreted in urine/feces respectively. Metabolites that were detected and identifiable (including coeluting metabolites reported together) are reported in this OM.

Cmax is the maximum plasma concentration.

AUCinf is the area under the plasma concentration-time profile from time zero extrapolated to infinite time.

AUClast is the area under the plasma concentration-time profile from time zero to the time of the last quantifiable concentration.

Fu is the fraction of unbound drug in plasma, which is calculated by Cu/C (where Cu represents unbound concentration and C represents total concentration).

Cmax,u is the unbound Cmax.

AUCinf,u is the unbound AUCinf.

AUClast,u is the unbound AUClast.

An adverse event (AE) was any untoward medical occurrence in clinical study participant, temporally associated with the use of study drug, whether or not considered related to the study drug. A serious AE (SAE) was defined as one of the following: was fatal or life-threatening; resulted in persistent or significant disability/incapacity; constituted a congenital anomaly/birth defect; was medically significant; required inpatient hospitalization or prolongation of existing hospitalization. A severe AE was defined as severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling, limiting self-care activities of daily living. Treatment-emergent AE was defined as an AE with onset date occurring during the on-treatment period (starting after or on the first dose but before the last dose plus at least 28 days). AEs included all SAEs and non-SAEs.

A treatment related adverse event (AE) was any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study drug, considered related to the study drug (assessed by the investigator \[Yes/No\]). A serious AE (SAE) was defined as one of the following: was fatal or life-threatening; resulted in persistent or significant disability/incapacity; constituted a congenital anomaly/birth defect; was medically significant; required inpatient hospitalization or prolongation of existing hospitalization. A severe AE was defined as severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling, limiting self-care activities of daily living. Treatment-emergent AE was defined as an AE with onset date occurring during the on-treatment period (starting after or on the first dose but before the last dose plus at least 28 days). AEs included all SAEs and non-SAEs.

Supine BP was measured with the participant's arm supported at the level of the heart, and recorded to the nearest mmHg after approximately 5 minutes of rest.

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. An 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.
