FibroGen Reports Third Quarter 2019 Financial Results

• Roxadustat Positive Pooled Phase 3 Efficacy and Cardiovascular Safety Data Presented Last Friday at American Society of Nephrology 2019 Kidney Week
• Plan to Submit Roxadustat U.S. NDA This Quarter

Conference Call Today at 5:00 p.m. Eastern Time/2:00 p.m. Pacific Time

SAN FRANCISCO, Nov. 11, 2019 (GLOBE NEWSWIRE) -- FibroGen, Inc. (NASDAQ: FGEN) today reported financial results for the third quarter of 2019 and provided an update on the company’s recent developments.

“The FibroGen team achieved many milestones over the past few months, culminating with the positive Phase 3 results for roxadustat reported at the American Society of Nephrology conference last week in Washington, D.C.,” said Jim Schoeneck, Interim Chief Executive Officer, FibroGen. “This set of global studies covered the spectrum of chronic kidney disease anemia and is believed to be the largest and most comprehensive ever reported. We expect the positive cardiovascular safety data, comparing roxadustat to placebo in non-dialysis patients and to epoetin alfa in patients on dialysis, along with the superior efficacy results, can serve as the basis for regulatory approval in the U.S. and other jurisdictions. We plan to submit an NDA in the U.S. by the end of this quarter for both dialysis and non-dialysis patients with our partner AstraZeneca, and an MAA in Europe by the end of first quarter 2020 by our partner Astellas, followed by submissions to other regulatory authorities.

“In addition, roxadustat is now approved for CKD patients with anemia in China and was approved in Japan for anemia in CKD patients on dialysis. Our other clinical programs advanced, as we initiated our roxadustat Phase 2 study to treat anemia in patients receiving chemotherapy and enrolled the first patients in our pamrevlumab Phase 3 programs for both idiopathic pulmonary fibrosis (ZEPHYRUS) and locally advanced pancreatic cancer (LAPIS).

“These major accomplishments demonstrate our commitment to the vision set by FibroGen’s founder and long-time CEO and Chairman, Tom Neff. We mourn his unexpected passing and are grateful for his leadership and rare ability to recognize and advance scientific innovation.”

Recent Developments – Roxadustat

Roxadustat is a novel, oral, first-in-class treatment for chronic kidney disease (CKD) patients with anemia, discovered by FibroGen and developed globally in conjunction with our partners AstraZeneca and Astellas. Groundbreaking science on the body’s oxygen-sensing mechanism and adaptation to hypoxia was awarded the 2019 Nobel Prize in Physiology or Medicine and serves as the foundation for the mechanism of action for roxadustat. Roxadustat increases hemoglobin by mimicking the body’s natural response to low oxygen.

American Society of Nephrology Kidney Week Presentations – November 6-9, 2019

• Clinical results presented from six roxadustat Phase 3 studies comprising over 8,000 anemia patients with chronic kidney disease, as well as pooled results for patients not on dialysis and on dialysis, including an incident dialysis subgroup
  
  • For additional data presented, please see our November 8, 2019 press release
    
  • Please also see our website for FibroGen’s ASN presentations
    

• Cardiovascular Safety Confirmed: In both non-dialysis dependent and dialysis dependent CKD anemia patients:
  • Non-Dialysis Dependent (NDD) (n=4270):
    • Risk of MACE, MACE+, and all-cause mortality in roxadustat patients was comparable to placebo based on a reference non-inferiority margin of 1.3
      
    • NDD results are based on ITT long-term follow-up analysis method agreed with the FDA
      
      
  • Dialysis Dependent (DD) (n=3880):
    
    • Risk of MACE and all-cause mortality in roxadustat patients were not increased compared to the active comparator, epoetin alfa
    • Roxadustat patients had a 14% lower risk of MACE+ than epoetin alfa patients 
      
      
  • Incident Dialysis (ID) Subgroup (n=1526): In the clinically important ID subgroup of patients, initiating dialysis within 4 months prior to randomization: 
    
    • Roxadustat patients had a 30% lower risk of MACE than epoetin alfa
    • Roxadustat patients had a 34% lower risk of MACE+ than epoetin alfa
    • Roxadustat patients had a trend towards lower all-cause mortality compared to epoetin alfa
      
      
  • Endpoint definitions, using centrally adjudicated events:
    
    • Time to first Major Adverse Cardiovascular Events (MACE), a composite endpoint including all-cause mortality, myocardial infarction, and stroke
    • Time to first MACE+, referring to MACE plus unstable angina and heart failure requiring hospitalization
    • Time to all-cause mortality

• Primary Efficacy Endpoints Met in all Individual Studies and Pooled Analyses
  
  • Met primary efficacy endpoint of mean change in hemoglobin (Hb) from baseline to average Hb weeks 28-52 in each of the six individual studies and in each of the two pooled efficacy analyses
  • Statistically superior to placebo in the NDD pool
  • Statistically superior to epoetin alfa in the DD pool
     
• Other Pooled Efficacy Analyses
  
  • Non-Dialysis Dependent
    
    • In the pooled analysis, roxadustat was superior to placebo, with significantly larger Hb increase than placebo regardless of iron-repletion status at baseline
    • Roxadustat treatment reduced the need for rescue treatment and red blood cell transfusion (RBC) compared to placebo
    • Roxadustat slowed the decline in renal function compared to placebo in patients eGFR >= 15
      
    • Roxadustat reduced LDL cholesterol
  • Dialysis Dependent
    
    • The larger Hb increase in patients treated with roxadustat vs. epoetin alfa was particularly notable in patients with inflammation (elevated CRP level)
    • Roxadustat treatment reduced the need for RBC transfusion compared to epoetin alfa
    • Less IV iron was required in patients receiving roxadustat versus patients receiving epoetin alfa

About Roxadustat
Roxadustat (FG-4592) is a first-in-class, orally administered small molecule HIF-PH inhibitor that promotes erythropoiesis through increasing endogenous production of erythropoietin, improving iron regulation, and overcoming the negative impact of inflammation on hemoglobin syntheses and red blood cell production by downregulating hepcidin. Administration of roxadustat has been shown to induce coordinated erythropoiesis, increasing red blood cell count while maintaining plasma erythropoietin levels within or near normal physiologic range in multiple subpopulations of chronic kidney disease (CKD) patients, including in the presence of inflammation and without a need for supplemental intravenous iron. Roxadustat is currently approved in China for the treatment of anemia in CKD patients on dialysis and patients not on dialysis and approved in Japan for the treatment of anemia in CKD patients on dialysis. Roxadustat is in Phase 3 clinical development in the U.S. and Europe and in Phase 2/3 development in China for anemia associated with myelodysplastic syndromes (MDS), and in a Phase 2 U.S. trial for treatment of chemotherapy-induced anemia.

Astellas and FibroGen are collaborating on the development and commercialization of roxadustat for the treatment of anemia in territories including Japan, Europe, the Commonwealth of Independent States, the Middle East, and South Africa. AstraZeneca and FibroGen are collaborating on the development and commercialization of roxadustat for the treatment of anemia in the U.S., China, and other markets in the Americas and in Australia/New Zealand as well as Southeast Asia.

About Pamrevlumab
Pamrevlumab is a first-in-class antibody developed by FibroGen to inhibit the activity of connective tissue growth factor (CTGF), a common factor in fibrotic and proliferative disorders characterized by persistent and excessive scarring that can lead to organ dysfunction and failure. Pamrevlumab is in Phase 3 clinical development for the treatment of idiopathic pulmonary fibrosis (IPF) and for the treatment of locally advanced unresectable pancreatic cancer (LAPC), and in Phase 2 clinical development for the treatment of Duchenne muscular dystrophy (DMD). The U.S. Food and Drug Administration has granted Orphan Drug Designation to pamrevlumab for the treatment of patients with IPF, LAPC, and DMD. Pamrevlumab has also received Fast Track designation from the U.S. Food and Drug Administration for the treatment of patients with IPF and LAPC. Across all clinical studies, pamrevlumab has consistently demonstrated a good safety and tolerability profile to date.
