Brief summary

The purposes of this study are: * To see how the new medicine (PF-07853578) under study is tolerated. And if there are any important side effects. And, how people feel after taking single increasing amount of the medicine by mouth. * To measure the amount of study medicine in your blood after the medicine is taken by mouth. This study is seeking for participants who: * are females of 18 to 65 years old and are not able to give birth to a child. * are males of 18 to 65 years old. * have body mass index of 16 to 31 kilograms per meter squared. * have a total body weight of more than 50 kilograms (110 pounds). Participants will be randomly selected to receive either study medicine (PF-07853578) or placebo (a pill that has no medicine in it). Participants may receive up to 4 amounts of study medicine and up to 2 amounts of placebo.

MeasureTime frameDescription
Number of Participants Reporting Treatment-Emergent Adverse Events (TEAEs)Day 1-11 in each period, along with the 29-36 day post final dose follow-upAn adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An adverse event is considered a TEAE if the event started during the effective duration of treatment. All events that started on or after the first dosing day and time/start time, if collected, but before the end of the study were flagged as TEAEs. The algorithm did not consider any events that started prior to the first dose date. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. 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.

Area Under the Plasma Concentration-Time Curve From Time Zero to Extrapolated Infinite Time (AUCinf)

Area under the plasma concentration-time curve from time 0 extrapolated to infinite time. AUCinf = AUClast + (Clast\*/kel), where Clast\* was the predicted plasma concentration at the last quantifiable timepoint estimated 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, AUClast = Area under the plasma concentration time-curve from zero to the last measured concentration.

Time frame: Pre-dose (0 hour) and 0.5 hour, 1 hour, 2 hours, 3 hours, 4 hours, 6 hours, 8 hours, 10 hours and 12 hours post Day 1 dosing of each treatment period (Periods 1-4)

Population: All participants randomly assigned to study intervention and who received at least 1 dose of study intervention and had at least 1 of the PK parameters of interest calculated.
