argenx Announces Planned Transition of Chief Operating Officer

March 2, 2023

Amsterdam, the Netherlands argenx (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced that Karen Massey will join argenx as Chief Operating Officer, effective March 13, 2023. Ms. Massey will succeed Keith Woods, who will remain at argenx for a transition period to support the launch of subcutaneous efgartigimod, after which he will retire and serve as a strategic advisor on the Commercial Committee of the argenx Board of Directors.

“Karen brings extensive commercial launch and leadership experience to argenx, specifically within neurology and autoimmune disease. Most recently, her leadership accelerated the post-launch performance of Ocrevus in multiple sclerosis, a dynamic market that is often compared to myasthenia gravis. Karen has a genuine passion for innovation and an ability to inspire large, diverse and global teams to deliver results by creating a sense of shared purpose and community,” commented Tim Van Hauwermeiren, Chief Executive Officer at argenx. “Karen's appointment is the result of careful succession planning and a thorough process to find the right leader at this important time in our company history. I am confident that she will make a significant impact at argenx as we work together to bring innovative medicines to patients.”

“I would like to extend a warm thank you to my friend and colleague, Keith Woods, who joined the company in 2018 with a commitment to build a global infrastructure ahead of our first commercial launch. He accomplished this and so much more – leading us through a very successful first launch-year while always inspiring our colleagues to keep the patient at the center of everything we do. I wish him well in his much-deserved next phase of life and look forward to his ongoing contributions as an advisor on our Board,” continued Mr. Van Hauwermeiren.

Ms. Massey has over 20 years’ experience in the pharmaceutical and biotechnology industry with an impressive breadth of experience across commercial, product development, corporate strategy & innovation. She joins argenx from Genentech (Roche Group), where she most recently served as Senior Vice President of Product Development and Global Clinical Operations. In this capacity, she led a global organization of more than 2,000 people across 24 countries and was accountable for operationalizing over 300 clinical trials within oncology, neuroscience, infectious diseases, immunology and ophthalmology. During her 9-year tenure at Genentech, Ms. Massey held various commercial leadership roles across marketing and business operations, including as the Vice President of the Multiple Sclerosis and Neuromyelitis Optica business, leading the team to accelerate the post-launch performance of Ocrevus. Ms. Massey started her biopharmaceutical career in marketing at Pfizer and returned there, after two years as a management consultant at Bain, to take on leadership positions in corporate strategy, sales and as a commercial lead in Latin America. Ms. Massey holds a Bachelor of Economics from the University of Sydney and a Master of Business Administration from the New York University Stern School of Business.

“argenx has demonstrated incredible growth transitioning from a research and development organization to an integrated, immunology company. This success has been built on a commitment to creating patient value through innovation. I am very excited by the opportunity to continue to build on that foundation as we look to realize the full potential of VYVGART and the pipeline candidates within our commercial franchises,” commented Ms. Massey.

Dynamic Top Pick List Update March 2026: Removing Aedifica – Adding Pr...

The tariff war between US and China has eased, but with the Iran conflict and an erratic Trump, uncertainty will continue into 2027. Energy prices have gone ballistic, with gas prices doubling in Europe and has hit the cyclical stocks hard. The highly anticipated AI productivity gains also will have to transpire sooner or later or a US market correction becomes unavoidable. While the macro-economic impact has been limited so far, a prolonged uncertain situation will result in economic damage. We...
