Cautionary note regarding forward-looking statements: The following information contains forward-looking statements, including statements regarding our expectations regarding the timing of reporting results from our clinical studies of KRN23, rhGUS, triheptanoin (in LC-FAOD and Glut1 DS), and SA-ER; our expectations regarding the timing of commencing clinical studies with respect to KRN23 and rhGUS; the design of studies for our product candidates; the likelihood of regulatory approvals for our product candidates; the potential market opportunities for commercializing our product candidates; our expectations regarding the potential market size and the size of the patient populations for our product candidates, if approved for commercial use; and other similar statements. Any forward-looking statements made by us reflect our current views with respect to future events or to our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by these forward-looking statements.
