Risk factors

We refer to the description of risk factors in the 2017 annual report, pp. 48-56, as supplemented by the description of risk factors in our annual report on Form 20-F filed with the U.S. Securities and Exchange Commission, pp. 5-45. In summary, the principal risks and uncertainties faced by us relate to: our financial position and need for additional capital; product development, regulatory approval and commercialization; our reliance on third parties; our competitive position; our intellectual property; our organization, structure and operation (including but not limited to certain risks related to our status as a U.S. publicly listed company) and market risks relating to our shares and ADSs.

We also refer to the description of the group’s financial risk management given in the 2017 annual report, pp. 132-135, which remains valid.
