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 prolylhydroxylase activity, which stimulates the body’s natural pathway to produce red blood cells.

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

After FibroGen overcome the hurdle of demonstrating to the CFDA that Roxa was safe enough to file an NDA, it presented itself as ready to conduct Phase 3 studies sufficient to obtain an NDA in the U.S. Food and Drug Administration (“FDA”) support. In 2019, FibroGen filed its NDA with the FDA for approval of Roxa for the treatment of anemia due to CRF.

The truth was beginning to show March 1, 2021 When FibroGen announced after market close that the FDA was planning a meeting of the Advisory Committee to review Roxa’s NDA, well over a year after its initial filing. An advisory committee meeting this late in the review process indicates that there is a problem with the application and, at best, could delay the FDA’s approval decision and, at worst, signal that the FDA may not approve the drug. Following the news, FibroGen’s share price fell $ 12.46 per share or 25%.

Then further April 6, 2021After the market closed, FibroGen issued a press release stating that FibroGen’s previously released 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, the complaint alleges that FibroGen was forced to admit that, contrary to previous statements, Roxa does not reduce the risk of cardiovascular events or hospitalization compared to a currently approved anemia injection, which was used as a control based on preliminary studies have decreased. specified stratification factors. Following the news, FibroGen’s share price fell $ 14.90or 43% to close at $ 19.74 per share on April 7, 2021.

The complaint alleges that throughout the classroom the defendants made false and / or misleading statements or failed to disclose: (1) Based on the safety data from the two Phase 3 studies of FibroGen in ChinaAny safety data obtained from the global phase 3 trials would require post hoc changes in stratification factors to meet FDA requirements. (2) FibroGen’s US primary cardiovascular safety analysis from Roxa’s global Phase 3 program for the treatment of CKD-related anemia included post-hoc changes in stratification factors. (3) FibroGens analyzes with the specified stratification factors led to higher hazard rates (point estimates of the relative risk) and 95% confidence intervals; (4) Based on these analyzes, FibroGen was unable to conclude that Roxa reduced (or was superior to) the risk of MACE + on dialysis and MACE and MACE + on dialysis compared to epoetin-alfa. (5) As a result, FibroGen faced significant uncertainty that its NDA for Roxa for the treatment of CKD anemia would be approved by the FDA. and (6) as a result of the foregoing, Defendants’ statements about FirboGen’s business, operations and prospects were materially false and misleading and / or had no reasonable basis at all relevant times.
