<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:12pt;">&nbsp;</p>
<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:11pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">SAN FRANCISCO, December 2, 2019 -- FibroGen, Inc. (NASDAQ: FGEN) today reported roxadustat has been included on the updated National Reimbursement Drug List (NRDL) released by China&#8217;s National Healthcare Security Administration (NHSA). Roxadustat is included on the NRDL for the treatment of anemia in chronic kidney disease (CKD), covering patients who are non-dialysis-dependent (NDD) as well as those who are dialysis-dependent (DD).</p>

<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:11pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">&#8220;Inclusion on the NRDL is a significant milestone and inflection point for the growth trajectory for roxadustat, as reimbursement provides affordability and access for patients on a national basis,&#8221; said Jim Schoeneck, Interim CEO, FibroGen. &#8220;We are grateful to the NHSA for recognizing the unmet medical need in the treatment of anemia associated with CKD, and the compelling value proposition of roxadustat.&#8221;</p>

<p style="margin-bottom:0pt;margin-top:0pt;text-indent:0%;font-size:11pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">&#8220;The timing of inclusion of roxadustat in NRDL is significant in that it underscores the Chinese government&#8217;s commitment to making innovative medicines accessible on an accelerated basis,&#8221; said Chris Chung, Managing Director, FibroGen China. &#8220;FibroGen and AstraZeneca will work diligently with provincial governments and hospitals to make this new treatment option available to patients. Roxadustat was among 97 drugs that were included on the updated NRDL list through negotiations, the highest number in history. Implementation will begin at the provincial level, starting January 2020.&#8221;&nbsp;&nbsp;&nbsp;&nbsp; </p>

HIF-PHIs are a brand-new class of drugs developed based on the groundbreaking science on the body&#8217;s oxygen-sensing mechanism and adaptation to hypoxia which was awarded the 2019 Nobel Prize in Physiology or Medicine. Results from the two pivotal China roxadustat Phase 3 clinical trials were published in the New England Journal of Medicine earlier in 2019.<sup style="font-size:85%;line-height:120%;vertical-align:top">1,2</sup> </p>

Although chronic kidney disease (CKD) may occur at any age, it is more common in aging populations, and its prevalence is increasing. CKD can be both a cause and a consequence of cardiovascular disease and is a critical healthcare issue. There is no treatment available that is curative or can stop kidney deterioration.

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.</p>
