Number of Participants With All-Causality Treatment-Emergent Adverse Events (TEAEs)	An AE was defined as 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. Any events occurring following start of treatment were considered as TEAEs.	From baseline up to 35 days after last dose of PF-07284890, up to 11 weeks
Number of Participants With Clinical Laboratory Abnormalities	The hematological (Lymphocytes/Leukocytes, Neutrophils/Leukocytes and Monocytes/Leukocytes), clinical chemistry (Urate and Potassium) and urinalysis (Urine Hemoglobin, Leukocyte Esterase and Bacteria) safety tests were assessed against the pre-specified criteria. The assessment did not take into account whether each participant's baseline test result was within or outside the laboratory reference range for the particular laboratory parameter.	From baseline up to 35 days after last dose of PF-07284890, up to 11 weeks
Number of Participants With Pre-Specified Categorization Criteria for Vital Signs	Supine systolic/diastolic blood pressure (BP) and pulse rate (PR) were measured and evaluated against pre-specified categorization criteria. The criteria included change of supine systolic/diastolic BP >=30 mmHg increase or decrease, and value of supine PR >120 beats per minute (bpm).	From baseline up to 35 days after last dose of PF-07284890, up to 11 weeks
Number of Participants With Pre-Specified Categorization Criteria for 12-Lead Electrocardiograms (ECGs)	Standard 12-lead ECGs utilizing limb leads were collected using an ECG machine that automatically calculated the heart rate (HR) and measured PR interval, QT interval, corrected QT interval using Fridericia's formula (QTcF), and time from ECG Q wave to the end of the S wave corresponding to ventricle depolarization (QRS) complex. The number of participants with PR/QRS values and percent change from baseline, QT interval values, and QTcF values and increases from baseline in the pre-specified categories were summarized in this outcome measure (OM).	From baseline up to 35 days after last dose of PF-07284890, up to 11 weeks
