Very good. Thank you, Mike, and good afternoon, everyone, and welcome to our fourth quarter and full year 2021 earnings call. Briefly, before we begin I would like to highlight that today is Rare Disease Day, which is especially relevant to us given our pamrevlumab Phase III programs and our roxadustat MDS program. As we enter 2022, we're excited about our future as we continue to advance our Phase III pamrevlumab clinical trials in three indications: continue our strong performance with roxadustat in China, launch of roxadustat in Europe and expand our research and development portfolio in the immuno-oncology and autoimmune space. On today's call, I intend to cover recent developments and key events, beginning with pamrevlumab. Juan Graham, our CFO, will then review the financials. After which, we will open up the call for your questions. Starting with Slide 3. FibroGen is positioned to create significant value for patients and shareholders by executing on our 3 areas of focus, number one, accelerating the development of pamrevlumab in three indications with significant unmet medical need, idiopathic pulmonary fibrosis, locally advanced unresectable pancreatic cancer and Duchenne muscular dystrophy. Number two, ensuring commercial success of roxadustat in patients with chronic kidney disease outside the U.S. while continuing to explore a path forward in the U.S. And number three, increasing our research productivity to advance novel programs that leverage internal expertise and accessing extra innovation for additional pipeline opportunities. Let's move to our clinical trials focusing on pamrevlumab on Slide 4. Pamrevlumab is a wholly owned asset in Phase III clinical trials for 3 highly important indications, as we said, IPF, LAPC and DMD. Today, we announced completion of enrollment of our LAPIS Phase III study of 284 patients with locally advanced unresectable pancreatic cancer. We also completed enrollment of the LELANTOS-1 Phase III study of 99 patients with non-ambulatory DMD. In the next few weeks, we expect to complete enrollment of the ZEPHYRUS-1 Phase III study of approximately 340 patients with IPF. Our Phase III ZEPHYRUS study is largely based on our Phase II PRAISE study, which demonstrated a meaningful reduction of lung function decline. Each of these diseases represents an important unmet medical need and collectively they constitute a significant market opportunity. We expect multiple pamrevlumab data readouts in 2023 and an interim analysis of LAPC later this year. I'd like to spend a few minutes highlighting our perspective on the significant opportunity we see with pamrevlumab in each of the three disease states, beginning with IPF on Slide 5. With a diagnosed prevalence of approximately 330,000 patients across the U.S., EU, China and Japan, the 2 key medicines comprising the IPF market generated over $3 billion in net revenue in 2020. Despite this market size, there remains significant unmet need with these two approved therapies as characterized by continued disease progression and challenging tolerability. There is a sentiment in the IPF community of limitations with the current therapies and a desire for additional therapeutic options. Given the limited number of late-stage products and development, we believe pamrevlumab, if approved, is well positioned to take advantage of this opportunity. If the Phase III ZEPHYRUS program reduces comparable results to the Phase II PRAISE trial, we believe pamrevlumab has the potential to help a sizable number of patients with IPF and be a very significant product for FibroGen. Turning now to Slide 6 and the locally advanced pancreatic cancer opportunity. Non-metastatic pancreatic cancer represents one of the greatest unmet missing oncology, given the diagnosed prevalence of almost 140,000 patients across the major regions combined with a low 5-year disease-free survival rate of around 10%. There have been limited treatment advances in the non-metastatic setting over the last two decades, with therapies failing to demonstrate survival benefits over the current standard of care. Similar to IPF, there's limited late-stage development activity in non-metastatic pancreatic cancer, which creates a meaningful opportunity for pamrevlumab if we can demonstrate an improvement in overall survival. As we said earlier, the LAPIS Phase III trial is fully enrolled, and we look forward to seeing if pamrevlumab could provide an important new treatment option for patients. Turning to Slide 7. We wrap up the pamrevlumab section with a snapshot of the DMD opportunity. Given the devastating nature of DMD and the relentless disease progression, we're hopeful that the LELANTOS clinical trial program can lead to an approved therapy that is so needed by the DMD community. With corticosteroids as the current standard of care, patients commonly deal with troublesome side effects as they continue to experience disease progression and loss of ambulation. While the currently approved exon-skipping therapies produce an increase in dystrophin levels, they only target a small proportion of DMD patients. There's clearly a need for therapies that can improve muscle function and prolonged ambulation by targeting the downstream pathological changes of DMD. We believe the antifibrotic mechanism of pamrevlumab may be a solution that can help these patients and their families. Now let's move to roxadustat on Slide 8. Following the European Commission approval of EVRENZO for the treatment of adult patients with symptomatic anemia associated with chronic kidney disease, Astellas has launched now in Germany, the United Kingdom, the Netherlands, Austria and the Nordic countries. The early feedback from health care providers prescribing EVRENZO has been positive. The anemia of CKD opportunity in Europe is significant, and EVRENZO has an important first-mover advantage relative to other HIF-PHIs. Regarding Roxadustat in the U.S., we and our partner, AstraZeneca, are in discussions on a potential path forward in anemia CKD. In November, FibroGen and AstraZeneca met with the FDA and discussed next steps following the advisory committee meeting. At this time, we are working together with AstraZeneca to determine those next steps. Moving now to China. As you can see on Slide 9, we are reporting total roxadustat net sales to distributors in China of $32 million for the fourth quarter. The total net roxadustat sales to distributor in China for 2021 was $186.1 million, significant growth over the $72.5 million in 2020. As a result of the price reduction associated with the NRDL listing renewal, the roxadustat net sales for the fourth quarter of 2021 reflected as onetime adjustment driven by a revaluation of channel inventory. FibroGen's portion of roxadustat net product revenue in China was $5.5 million for the fourth quarter and $47.6 million for the full year 2021 on a U.S. GAAP basis. Juan will dive deeper into further detail in the finance update. We have continued to see broad adoption across the three segments of hemodialysis, peritoneal dialysis and non-dialysis and continued to see strong performance of roxadustat in China. Since the launch of roxadustat in mid 2019, a primary focus of our commercialization efforts has been to secure hospital listings, which is the right to be prescribed to a particular hospital. As of the end of 2021, we're listed in hospitals that represent approximately 80% of the addressable anemia CKD market. Roxadustat was included in the 2021 NRDL with a meaningful reduction in price. However, we do expect roxadustat net sales growth for the full year in China driven by significant growth in volume. As you can see on Slide 10, roxadustat continues to drive the expansion of the anemia of CKD category and is capturing share in an expanding market. Roxadustat captured the large majority of the category growth for the 12 months ended December 2021 over the same period in 2020. Finally, as shown on Slide 11, roxadustat is the number one branded treatment for anemia of CKD in China for the past 12 months, achieving a value of share of 36% in the most recent quarter within that segment that includes all ESA products and roxadustat currently the only HIF-PHI in the market. We look forward to keeping you updated as we advance our long-term goal of making roxadustat the standard of care in treating China's CKD anemia patients. I will now turn the call over to our CFO, Juan Graham for the financial update. Juan?
