Risks related to commercialization

The marketing and sale of filgotinib or future approved products may be unsuccessful or less successful than anticipated. We are heavily dependent on the success of filgotinib, which is approved for the treatment of RA in the European Union, Great Britain and Japan, and for the treatment of UC in the European Union and Great Britain, and under regulatory review for the treatment of ulcerative colitis in Japan.

The commercial success of filgotinib and of any future products will depend upon the degree of market acceptance by physicians, healthcare payers, patients, and the medical community.

We have limited sales and distribution experience and are currently building a marketing and sales organization. We expect to continue to invest significant financial and management resources to continue to build these capabilities and to establish a European commercial infrastructure. To the extent any of our product candidates for which we maintain commercial rights is approved for marketing, if we are unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell our products, we may not be able to market and sell any product effectively, or generate product revenues.

Coverage and reimbursement decisions by third-party payers may have an adverse effect on pricing and market acceptance. Legislative and regulatory activity may exert downward pressure on potential pricing and reimbursement for any of our product candidates, if approved, that could materially affect the opportunity to commercialize.
