NCT05431153

Brief Summary

This is a single dose crossover pharmacokinetic (pharmacokinetics helps in understanding how the drug is changed and eliminated from the body after a participant takes it) study in healthy participants. The study consists of 5 treatments, and each participant will be randomized to receive 4 of the treatments in separate periods in a specific sequence. Each treatment consists of a single dose of PF-07104091 and the treatments differ by tablet formulation and/or whether the dose is to be given under fasted or fed conditions. Plasma pharmacokinetics of PF-07104091 will be assessed following each dose to determine the effect of tablet formulation and fed condition on the relative bioavailability of PF-07104091.

Outcome Measures

Primary Outcomes (2)

  • Area Under the Plasma-Concentration Time Curve From Time Zero (0) Extrapolated to Infinity (AUCinf) of PF-07104091 for Treatment A, B, and C

    AUCinf was calculated as AUClast + (Clast/kel) where Clast was the predicted plasma concentration at the last quantifiable time point from the log-linear regression analysis and kel was the terminal phase rate constant calculated by a linear regression of the log linear concentration-time curve.

    Predose, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, and 48 hours post-dose

  • Maximum Observed Plasma Concentration (Cmax) of PF-07104091 for Treatment A, B and C

    Cmax was maximum observed concentration. Cmax was observed directly from data.

  • Any condition possibly affecting drug absorption (eg, gastrectomy, cholecystectomy).
  • History of human immunodeficiency virus (HIV) infection, hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HBsAg), Hepatitis B core antibody (HBcAB) or hepatitis C antibody (HCVAb). Hepatitis B vaccination is allowed.
  • Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality or other conditions or situations related to COVID-19 pandemic (eg, contact with positive case, residence, or travel to an area with high incidence) that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
  • Use of prescription or nonprescription drugs and dietary and herbal supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention.
  • A positive urine drug test.
  • History of sensitivity to heparin or heparin induced thrombocytopenia.
