Good day, ladies and gentlemen, and welcome to the Orchard Therapeutics Second Quarter 2019 Earnings Conference Call. At this time, all participants are in a listen-only mode. Later, there will be a question and answer session and instructions will follow at that time. [Operator instructions] As a reminder, this conference call is being recorded.
I would now like to turn the conference over to Renee Leck, Director of Investor Relations.
