This is Zack Fuss, an investor at Irenic Capital. Today, we're breaking down Argenx, an immunology company founded in 2008 by its three founding partners. Today, it's a $30 billion company set to produce over a billion dollars in sales. They're known for their skill in developing antibodies for complex disease targets and owe a large part of their medical breakthroughs to llamas, which have similar antibodies in their immune system to those found in humans. 
To break down Argenx, I'm joined by Julia Angeles, an investment manager at Baillie Gifford. Throughout this conversation, we'll discuss how Argenx navigates the complex world of drug development, clinical trials, regulatory approvals, and the ultimate commercialization of autoimmune therapies. We'll also learn more about their transition from a venture capital backed business to its 2017 IPO, and today, a meaningful revenue generating business. We hope you enjoy this business breakdown.

Note: This conversation was recorded on 19 July 2023.
