FibroGen is a biopharmaceutical company that develops drugs for the treatment of anemia, fibrotic diseases and cancer. Its most advanced product is roxadustat, an oral small molecule inhibitor of hypoxia-inducible factor prolyl hydroxylase activity which works by stimulating the body’s natural pathway for the production of red blood cells. In 2019, the Company filed its New Drug Application (“NDA”) with the United States Food and Drug Administration (“FDA”) for the approval of roxadustat for the treatment of anemia due to kidney disease. chronic (“CKD”).

Anemia can be a serious condition in which patients have insufficient numbers of red blood cells and low levels of hemoglobin, a protein in red blood cells that carries oxygen to cells throughout the body. Anemia in CRF is associated with an increased risk of hospitalization, cardiovascular complications, and death, also frequently causing severe fatigue, cognitive dysfunction, and reduced quality of life. Severe anemia is common in patients with CKD, cancer, myelodysplastic syndromes, inflammatory diseases, and other serious illnesses.

Anemia is particularly prevalent in patients with CRF. The prevalence of CRF in the adult population is estimated to be 10-12% worldwide and is generally a progressive disease characterized by progressive loss of renal function which can eventually lead to renal failure or end-stage renal disease, requiring dialysis or kidney transplant to survive. Blood transfusion is used to treat severe, life-threatening anemia. However, blood transfusions reduce the patient’s chances of having a kidney transplant and increase the risk of infections and the risk of complications such as heart failure and allergic reactions.

The complaint alleges that, throughout the Class Period, the Defendants made materially false and misleading statements regarding the activities of the Company. Specifically, the Defendants have made false and / or misleading statements and / or failed to disclose: (i) that the Company’s prior disclosures of primary cardiovascular safety testing in the United States of the roxadustat Phase 3 program for the treatment of anemia submitted under IRC included one-time post-changes in stratification factors; (ii) that FibroGen analyzes with pre-specified stratification factors result in higher risk ratios (point estimates of relative risk) and 95% confidence intervals; (iii) that, on the basis of these analyzes, the Company could not conclude that roxadustat reduces the risk of (or is greater than) MACE + in dialysis, and MACE and MACE + in incident dialysis compared to epoetin -alfa; (iv) that, therefore, the Company faced significant uncertainty as to whether its NDA for roxadustat as a treatment for CKD anemia would be approved by the FDA; and (v) that as a result of the foregoing, the Defendants’ statements regarding the activities, operations and prospects of the Company were substantially misleading and / or lacked reasonable basis.

On April 6, 2021, FibroGen issued a press release “provid[ing] clarification of certain prior disclosures of US primary cardiovascular safety testing of the phase 3 roxadustat program ”. The CEO of the Company said that “[a]As members of senior management were preparing for the next FDA advisory committee meeting, we realized that key cardiovascular safety analyzes included post-hoc changes in stratification factors ”and“ quickly decided to clarify this issue. with the FDA and to communicate with scientists and investment communities.

Also on April 6, 2021, STAT + published an article titled “Fibrogen Admits Fake Cardiac Safety Data for Experimental Anemia Pill Shared with FDA, Investors.” The article stated, among other things, that “Fibrogen admitted on Tuesday that the company has been touting fake heart safety data for its experimental anemia pill for at least two years – a shocking revelation that raises even more questions about the drug approval “, that”[w]When these changes have been removed and the cardiac safety data of roxadustat has been analyzed as specified in the analysis plan, the results are less robust ”and than“[a]Going through three studies involving dialysis patients, Fibrogen said it could no longer conclude that roxadustat reduced the risk of cardiovascular events or hospitalization compared to a currently approved anemia injection used as a control.

As a result of these disclosures, the company’s stock price fell $ 14.90, or 43%, to close at $ 19.74 per share on April 7, 2021, on significant volume. FibroGen shares continued to decline on April 8, 2021, to close at $ 18.81 per share, down $ 0.93 per share, or 4.7%, on a large volume basis.
