The complaint alleges that throughout the Class Period, Defendants made materially false and/or misleading statements and failed to disclose that: (1) that the Company's prior disclosures of U.S. primary cardiovascular safety analyses from the roxadustat Phase 3 program for the treatment of anemia certain safety analyses submitted in connection with CKD included post-hoc changes to the stratification factors; (2) that FibroGen's analyses with the pre-specified stratification factors result in higher hazard ratios (point estimates of relative risk) and 95% confidence intervals; (3) that, based on these analyses the Company could not conclude that roxadustat reduces the risk of (or is superior to) MACE in dialysis, and MACE and MACE in incident dialysis compared to epoetin-alfa; (4) that, as a result, the Company faced significant uncertainty that its NDA for roxadustat as a treatment for anemia of CKD would be approved by the FDA; and (5) that, as a result of the foregoing, defendants' statements about the Company's business, operations, and prospects were materially misleading and/or lacked a reasonable basis.
