A Study to Understand the Effect of a Study Medicine Called ARV-471 on Rosuvastatin in Healthy Adults

AN INTERVENTIONAL, PHASE 1, OPEN-LABEL, FIXED-SEQUENCE, 2-PERIOD STUDY TO EVALUATE THE EFFECT OF A SINGLE ORAL DOSE OF ARV-471 (PF-07850327) ON THE PHARMACOKINETICS OF ROSUVASTATIN IN HEALTHY PARTICIPANTS

The purpose of this study is to understand if ARV-471 affects how a BCRP substrate (rosuvastatin) gets into the body in healthy adults.

All participants in this study will receive one dose of rosuvastatin alone by mouth in Period 1. In Period 2, everyone will receive one dose of ARV-471 by mouth 90 min before one dose of rosuvastatin by mouth. The levels of rosuvastatin in Period 1 will be compared to the levels of rosuvastatin in Period 2 to determine if ARV-471 affects how rosuvastatin gets into the body differently in healthy adults.

All participants will stay at the study clinic for 10 days and 9 nights.

Inclusion Criteria:

• Male and/or female participants of non-childbearing potential must be 18 to 65 years of age, inclusive at the time of signing informed consent document.

• Pregnant female participants; breastfeeding female participants; Male participants with partners currently pregnant; fertile male participants who have partners of childbearing potential and are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and for 90 days after the last dose of investigational product.
• Participants with known history of hypersensitivity to statin medication, sensitivity to ARV-471 or rosuvastatin or any of the formulation components of ARV-471 or rosuvastatin.
• 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 that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
• Previous administration with an investigational product (drug or vaccine) within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of study intervention used in this study (whichever is longer).
• A positive urine drug test.
• History of use of tobacco or nicotine-containing products in excess of the equivalent of 5 cigarettes/day or 2 chews of tobacco/day.
• History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening.
