On August 18, 2019, the company issued a press release announcing “Positive Results for Phase 3 Pooled Safety and Efficacy of Roxadustat”. Shortly after, on December 23, 2019, FibroGen announced that it had submitted a new drug application to the Food and Drug Administration for roxadustat.

On April 6, 2021, the company announced that its previously disclosed safety data included undisclosed post-hoc changes in stratification factors and no analysis based on the specified stratification factors. As a result of these changes, FibroGen had to admit that, contrary to previous presentations, Roxadustat did not reduce the risk of cardiovascular events or hospitalization when compared to a currently approved anemia injection used as a control based on predetermined stratification factors.

In that news, the company’s stock price fell $ 14.90, or 43%, to close at $ 19.74 per share on April 7, 2021.

The complaint, filed on April 12, 2021, alleges that defendants have not disclosed to investors: (i) that the company’s prior disclosure of primary cardiovascular safety testing in the United States from the Roxadustat Phase 3 program for the treatment of CKD -Anemia post-hoc were changes in stratification factors; (ii) that FibroGens analyzes with the given stratification factors lead to higher hazard rates (point estimates of the relative risk) and 95% confidence intervals; (iii) based on these analyzes, the Company has not been able to conclude that Roxadustat reduces (or is superior to) the risk of MACE + on dialysis and MACE and MACE + on dialysis compared to epoetin-alfa; (iv) as a result, the Company faced significant uncertainty that its NDA for roxadustat for the treatment of CKD anemia would be approved by the FDA; and (v) that as a result of the foregoing, Defendants’ statements about the Company’s business, operations and prospects were materially misleading and / or unfounded.
