SECONDARY outcome

Timeframe: Up to Day 32 (31 days after investigational product administration)

Population: All participants who received PF-06865571.

An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who receives study drug. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were events following start of treatment.
