FibroGen is a biopharmaceutical company developing drugs to treat anemia, fibrotic diseases, and cancer. Its most advanced product is Roxadustat (“Roxa”), an oral low molecular weight inhibitor of hypoxia-inducible factor prolyl hydroxylase activity, which works by stimulating the body’s natural pathway for red blood cell production.

The class period begins on October 18, 2017, when FibroGen announced that the Chinese Food and Drug Administration has accepted its new drug application (“NDA”) for Roxa based on two Phase 3 studies in China, “a study to CKD “. [chronic kidney disease] Comparison of Roxadustat with a brand name epoetin alfa[] and a non-dialysis-free CKD study comparing roxadustat to placebo. “Both studies had” met their primary efficacy endpoints without identifying any new or unexpected safety signals. “

On April 6, 2021, after market close, FibroGen released a press release revealing that FibroGen’s previously published safety data contained undisclosed post-hoc changes in stratification factors and did not include analyzes based on the pre-established stratification factors. As a result of these changes, the complaint alleged that FibroGen was forced to admit that, contrary to previous representations, Roxa reduced the risk of cardiovascular events or hospitalization compared to a currently approved anemia injection, which was used as a control based on pre-specified stratification factors. Following this news, FibroGen’s share price fell $ 14.90, or 43%, to close at $ 19.74 per share on April 7, 2021.

The story goes on

The complaint alleges that during the class action period, defendants made false and / or misleading information or failed to disclose: (1) Based on the safety data from the two Phase 3 trials of FibroGen in China, all safety data from the global Phase 3 trials would require subsequent changes to the stratification factors to meet the requirements of the US Food and Drug Administration (“FDA”); (2) FibroGen’s publications on primary cardiovascular safety assessments in the United States from Roxa’s global Phase 3 program for the treatment of anemia submitted for CKD included post-hoc changes in stratification factors; (3) The analyzes of FibroGen with the previously defined stratification factors led to higher hazard ratios (point estimates of the relative risk) and 95% confidence intervals; (4) Based on these analyzes, FibroGen was unable to conclude that Roxa reduced (or superior to) the risk of MACE + on dialysis and MACE and MACE + on incident dialysis compared to epoetin-alfa; (5) As a result, FibroGen faced significant uncertainty that its NDA for Roxa for the treatment of anemia in CKD would be FDA approved; and (6) as a result of the foregoing, Defendants’ statements regarding FirboGen’s business, operations and prospects were materially false and misleading and / or were inadequate at all relevant times.
