The purpose of this study is to learn about: * How PF-07328948 is changed and removed from the body after taking * Safety of PF-07328948 * The extent to which undesirable effects can be tolerated after taking PF-07328948 for the possible treatment of heart failure This study is seeking participants who: * Are healthy Chinese adults who are aged 18 years old and older * Have body mass index from 18.5 to under 28 kilograms/meter square * Have a total body weight over 50 kilograms (110 pounds) * Do not have a history of blood clots blocking an artery or vein All participants in this study will receive oral daily PF-07328948 at the study clinic for 7 consecutive days. The experiences of the participants receiving the study medicine will be looked at. This will help to see if the study medicine is safe. Participants will take part in this study for around 10 weeks. During this time, participants will have 1 study visit at the study clinical and 1 contact over the phone.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Pfizer Inc (PFE) is the sponsoring company for this trial. BiotechSign currently grades this company F (33/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
