The purpose of the study is to look at how various tablets of a study medicine called vepdegestrant are processed in the body. This will be studied in healthy adult participants after food. This study looks at how the medicine is changed and removed from the body after a participant takes it. This study is seeking for participant who: * are healthy males, and healthy females who do not have the possibility to have children. * are 18 years of age or older. * weigh more than 45 Kilograms (99 pounds). The study consists of 3 treatments. Each participant will be assigned by chance to receive the 3 treatments in a certain sequence. This will be done over 3 study periods. Each treatment consists of a single amount of vepdegestrant taken by mouth in each study period. There will be a washout period between each study periods. The washout period is the time allowed for the medicine to get washed out from the body. How the medicine was processed will be calculated following each dose in each period. The total study duration is about 13 weeks.

Inclusion Criteria: * Male participants and/or female participants of non-childbearing potential aged 18 years or older (or the minimum age of consent in accordance with local regulations) at screening who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, vital signs and standard 12-lead ECGs. * BMI of 16-32 kg/m2; and a total body weight \>45 kg (99.2 lb). * Capable of giving signed informed consent, which includes compliance with requirements and restrictions listed in the informed consent document (ICD) and in this protocol. * Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures. Exclusion Criteria: * Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing). * Any medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study. * Participants with known history of sensitivity to vepdegestrant or any of the formulation components of vepdegestrant. * Use of prescription or nonprescription drugs, including vitamins, dietary, herbal supplements, grapefruit/grapefruit containing products, and Seville orange/Seville orange containing products within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention. A longer washout is required for those that fall into the categories below: * Moderate or strong CYP3A inducers which are prohibited within 14 days plus 5 half-lives prior to the first dose of study intervention. * Moderate or strong CYP3A inhibitors which are prohibited within 14 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention (unless otherwise indicated in the protocol). * Standard 12-lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results. * History of sensitivity to heparin or heparin-induced thrombocytopenia.
