|Lead Plaintiff Motion Deadline||June 11, 2021|
In 2019, FibroGen filed its New Drug Application (“NDA”) with the U.S. Food and Drug Administration (“FDA”) for the approval of roxadustat for the treatment of anemia due to chronic kidney disease (“CKD”).
On April 6, 2021, after the market closed, FibroGen issued a statement “provid[ing] clarification of certain prior disclosures of U.S. primary cardiovascular safety analyses from the roxadustat Phase 3 program for the treatment of anemia of chronic kidney disease (‘CKD’).” Specifically, the Company stated that the safety analyses “included post-hoc changes to the stratification factors.” FibroGen further revealed that, based on analyses using the pre-specified stratification factors, the Company “cannot 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.”
On this news, the Company’s share price fell $14.90, or 43%, to close at $19.74 per share on April 7, 2021, thereby injuring investors. The share price continued to fall during the next trading session by $0.93, or 4.7%, to close at $18.81 per share on April 8, 2021, thereby injuring investors further.
The complaint filed alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (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, Defendants' statements about its business, operations, and prospects, were materially false and misleading and/or lacked a reasonable basis at all relevant times.
