Study Endpoints

Primary Endpoints

Total Recovery of Radioactivity in Urine, Expressed as Percentage of Total Radioactive Dose Administered
Predose, in intervals of 0-6, 6-12, 12-24, 24-48, 48-72, 72-96 hours postdose on Day 1, and each subsequent 24 hours interval up to discharge (maximum 14 days)

Radioactivity excreted in urine was reported as the percentage of the administered radioactivity excreted at each time interval, cumulatively through that interval and the total percent of dose recovered in urine.

Total Recovery of Radioactivity in Feces, Expressed as Percentage of Total Radioactive Dose Administered
Predose, in intervals of each 24 hours post dose on Day 1 up to discharge (maximum 14 days)

Radioactivity excreted in feces was reported as the percentage of the administered radioactivity excreted at each time interval, cumulatively through that interval and the total percent of dose recovered in feces.

Total Recovery of Radioactivity in Total Excretion (Urine + Feces), Expressed as Percentage of Total Radioactive Dose Administered
Predose, in intervals of each 24 hours post dose on Day 1 up to discharge (maximum 14 days)

Radioactivity excreted in urine and feces was reported as the percentage of the administered radioactivity excreted at each time interval, cumulatively through that interval and the total percent of dose recovered in urine and feces.

Relative Abundance of PF-07265803 and Its Metabolites in Plasma, Expressed as Percentage of Radioactivity
Predose, 0.5, 1, 2, 3, 4, 6, 9, 12, 24, 36, 48, 72, 96, 120 hours post dose on Day 1

Plasma homogenates were extracted for total radioactivity, and processed samples were analyzed by HPLC with radiochemical detection for quantitation of \[14C\]PF-07265803-derived components and by HRMS for identification of PF-07265803 and metabolites after a single 400-mg (100 μCi) oral dose of \[14C\]PF-07265803. Relative abundance of the metabolites of \[14C\]PF-07265803 in plasma based on \[14C\] quantitation was reported, expressed as percentage of radioactivity. PF-07265803 and four metabolites identified/characterized in human plasma including PF-07327859, PF-07327890, PF -07327860, and des(dimethylamino)-dioxy-PF-07265803 (m/z 461) were presented below. The plasma analysis was done with a single master pool sample (individual participants pooled based on time and from these a single master pool of all participants in one tube) due to the low amount of radioactivity in the plasma, hence there would be no mean or standard deviation.

Relative Abundance of PF-07265803 and Its Metabolites in Feces, Expressed as Percentage of Radioactivity
Predose, in intervals of each 24 hours post dose on Day 1 up to discharge (maximum 14 days)

Fecal homogenates were extracted for total radioactivity, and processed samples were analyzed by HPLC with radiochemical detection for quantitation of \[14C\]PF-07265803-derived components and by HRMS for identification of PF-07265803 and metabolites after a single 400-mg (100 μCi) oral dose of \[14C\]PF-07265803. In this outcome measure, relative abundance of the metabolites of \[14C\]PF-07265803 in feces based on \[14C\] quantitation was reported, expressed as percentage of radioactivity.
