The purpose of this study is to learn how quickly and to what extent the study medicine (PF-07054894) is absorbed, broken down, and eliminated from the body.
There are two groups in this study: * Cohort 1 (which has 2 periods) * Cohort 2 (has 1 period) Participants will only have to participate in one of the 2 Cohorts. * In Cohort 1 - Period 1, the study will check how the study medicine (PF-07054894) is removed from the body. In Period 2, the study will find out how well the study medicine is absorbed by the body when given by mouth compared to an intravenous route. (solution of the study medicine is injected directly into a vein). For this period, the PF-07054894 that is injected into the vein is radioactively labeled, but the dose given by mouth is not radioactively labeled. Radioactively labelled are compounds where one or more atoms have been replaced with a radioactive element. This allows researchers to track their movement within cells. * In Cohort 2 - a different radioactive labelled material is used than the one of Cohort 1. This is done to see how PF 07054894 is removed from the body. The study will also look at how safe the study medicine is and how well it is tolerated when it is given to healthy people. Participants in Cohort 1 will be involved in this study for about 10 weeks and about 8 weeks for those in Cohort 2. Participants in Cohort 1 will stay in the study clinic in Period 1 for up to 15 days (14 nights) and 8 days (7 nights) in Period 2. Participants in Cohort 2 will stay in the study clinic for up to 15 days (14 nights). For Period 1 of both Cohort 1 and 2, the study doctor will be checking the levels of radioactively labeled study medicine in body frequently from Day 7 onwards in urine, stool, and any vomit and will let participants know as soon as possible if they have to stay longer or if they can go home. The duration of participants' stay will depend on how quickly or slowly the radioactively labeled study compound leaves their body. For Period 2, participants will have to stay in the study clinic for 8 days (7 nights) and leave the study clinic on Day 7. However, if the study doctor believes it is necessary to protect participant's health, they may be asked to remain in the study clinic after Day 7.
