Thank you, Jennifer, and good afternoon, everyone. We appreciate you joining us for today's update. I'll start today's call with a discussion of narsoplimab, our fully human antibody targeting MASP-2, which is the effector enzyme of the lectin pathway of complement. Let's first focus on our program in hematopoietic stem cell transplant-associated thrombotic microangiopathy, or TA-TMA. With respect to our rolling biologics license application, or BLA, for narsoplimab in the treatment of TA-TMA, the nonclinical and CMC sections of the BLA have already been submitted and all clinical sections are complete. This includes all detailed narratives on all study patients and on compassionate use patients. The narratives include patient historical data that were obtained at the clinical sites and that predate enrollment in the pivotal clinical trial. These narratives were requested by FDA as part of our agreement to convert our Phase II clinical trial to a pivotal trial. We are submitting them as part of the BLA, which we expect will streamline FDA's overall review process. The last components of the BLA, the clinical sections and the narratives will be submitted next week. A few weeks ago, the final clinical data included in the BLA were presented by Professor Alessandro Rambaldi of the University of Milan and Head of Hematology and Bone Marrow Transplantation at PPG, Papa Giovanni XXIII Hospital; and by Dr. Miguel Perales, chief of the adult Bone marrow transplant service at Memorial Sloan Kettering Cancer Center. The final complete response rate, the primary efficacy endpoint was even higher than the preliminary data reported earlier this year. This was a very sick population with multiple comorbidities. Compared to the agreed efficacy threshold for the primary endpoint of 15%, 61% of all patients who received at least 1 dose of narsoplimab and 74% of patients receiving the protocol-specified narsoplimab treatment for at least 4 weeks were complete responders. The secondary endpoints were similarly impressive. 100-day survival expected to be no more than 20%, again, was multiples of that, 68% in patients receiving at least 1 dose, 83% in the per protocol treated group and 94% in complete responders. Median estimated overall survival was 274 days in all patients, 361 days in those receiving at least 4 weeks of dosing and could not be estimated in the responder group because, given the clinical response to narsoplimab, more than half the patients we're still alive out to as long as roughly 4 years following treatment. As a reminder, narsoplimab has received FDA's Breakthrough Therapy designation and orphan drug designations from both FDA and EMA for the treatment of TA-TMA. We have requested and expect that our BLA will receive priority review. As we look forward to FDA approval of narsoplimab for the first of what we expect will be a series of approved indications, our launch readiness continued to progress throughout the third quarter. We expanded our commercial and medical affairs infrastructure, identified the final candidates of our sales leadership team, expanded our medical science liaison team, developed field and payer training modules, hired our field market development managers and expanded our advocacy initiatives with key organizations throughout the transplant community. Accomplishments in Q3 included the filing and presentation for our international classification of diseases or ICD-10 coding applications for narsoplimab and for TA-TMA. This enables straightforward reimbursement of the drug. In September, in a process hosted by CMS, we requested an ICD-10 procedure code for administration of narsoplimab. At that meeting, CMS made a preliminary recommendation to accept the code, and we are awaiting the final decision in early 2021. We also requested an ICD-10 diagnostic code for TA-TMA from the Centers for Disease Control and Prevention, or CDC. The creation of a diagnostic code would help clinicians payers and others accurately track the incidence and severity of the illness and would likely increase the number of patients who are accurately diagnosed. Here again, CDC has preliminarily indicated its support for a TA-TMA diagnosis code. As we continue to advance toward both procedure and diagnostic ICD-10 codes, we have closely collaborated with and appreciate the strong support from key transplant societies and organizations. These include the Center for International Blood and Marrow Transplant Research, the American Society of Transplant and Cellular Therapy, the American Society of Hematology, the Pediatric Transplantation and Cellular Therapy Consortium; Be the Match National Bone Marrow Donor program, the European Society for Blood and Marrow Transplantation and the TA-TMA Guidelines working group consisting of some of the most respected transplant physicians across the U.S. and Europe. We are executing on a comprehensive publication strategy and a long list of manuscripts highlighting the biology and clinical benefits of narsoplimab in TA-TMA have begun appearing in peer-reviewed journals. A manuscript by researchers at Weill Cornell Medical college led by Professor Jeffrey Lawrence was recently published in the peer-reviewed journal Clinical and Experimental Immunology. And next month, Omeros will have a significant presence and a presentation at the annual meeting of the American Society of Hematology. In summary, the regulatory and commercial efforts around narsoplimab and TA-TMA are moving ahead nicely. We expect that FDA will grant us a priority review. And we look forward to bringing this much needed therapy to patients as soon as possible. Our work in TA-TMA and other endothelial injury syndromes allowed us in collaboration with Professor Alessandro Rambaldi to recognize the pathophysiologic similarities between TA-TMA and COVID-19. Both our endothelial injury syndromes and involved as an early and central component, MASP-2 endolectin pathway of complement. I won't on this call, go into detail about how the mechanism of narsoplimab and the pathophysiology of COVID-19 dovetail almost perfectly. Instead, I'll refer you to our Investor Relations website, where you'll find a presentation clearly laying out that information. Suffice to say that numerous leading research groups around the world including Omeros' complement labs at the University of Cambridge, have demonstrated that COVID-19 is caused by overactivation of the innate immune response and is mediated by 3 major components: lectin pathway-driven complement activation, inflammation and coagulation. We believe that narsoplimab is the only drug that effectively blocks all 3. And the dramatic clinical outcome is specifically survival that we've seen in treating critically ill COVID-19 patients with narsoplimab are consistent with those seen with the drug in TA-TMA, underscoring the shared pathophysiology between these two disorders. In August, we announced that 6 COVID-19 patients in Bergamo, Italy, all with high-risk factors and deteriorating respiratory stratus requiring mechanical ventilation were treated with narsoplimab under compassionate use. All 6 patients clinically recovered, survived and were discharged from the hospital. Laboratory values, specifically circulating endothelial cell counts, IL-6, ILH C-reactive protein LDH, AST and D dimers all normalized. Retrospective control groups with similar baseline characteristics and disease severity had mortality rates of 32% and 53%. The results of the study were published in the peer-reviewed journal, Immunobiology. It's now become clear and multiple groups internationally have reported on this that COVID-19 is not a one-and-done disease. Instead, as many as 70% or more patients who have reportedly recovered from the initial bout of COVID-19 suffer serious longer-term effects, cognitive impairment and other CNS problems as well as cardiac pulmonary and multi-organ sequelae. The social health care burden and associated costs of these long-standing disease effects could be staggering. So we evaluated our Bergamo patients 5 to 6 months after their last treatment with narsoplimab. Remarkably, all patients were doing well, and none were found to have any clinical or laboratory evidence of COVID-19-related sequela. All of their clinical assessments and laboratory values, including D dimer levels, a marker of hypercoagulation were entirely normal. As the surge in COVID-19 cases increases, we have continued to create critically ill patients both in the U.S. and in Italy under compassionate use. To our knowledge, no treatment for severely ill COVID-19 patients rationally addresses the biology of the disease nor has shown the same remarkable clinical outcomes as has narsoplimab. The need to make narsoplimab widely and rapidly available was advocated by a panel of experts in September. On the Demi Colton public service webcast and in a recent article featured in the American Council on Science and Health and subsequently published in real clear markets. The article's author, Dr. Henry Miller is Senior Research Fellow at the Pacific Research Institute, former Robert Weston Fellow at Stanford's Hoover Institution and had an impressive 15-year career at FDA. Our discussions have progressed with leadership across BARDA, NIAID, NCAT and NIH regarding narsoplimab for the treatment of critically COVID-19 patients. With COVID-19 surging again globally and other therapeutics with really greater fanfare having failed to show benefit in critically ill COvID-19 patients, the decision-makers in these government agencies are increasingly focused on narsoplimab. This awareness of and interest in narsoplimab extends to a future Biden administration as well. We also have received requests to include narsoplimab and platform trials for COVID-19, and those discussions are advancing. In addition to our work with narsoplimab in COVID-19 and completing the rolling BLA submission in TA-TMA. Our other Phase III programs for narsoplimab continued to progress in the third quarter. Our Phase III trials in atypical hemolytic uremic syndrome or aHUS; and in immunoglobulin a or IgA nephropathy are ongoing. Our focus remains on IgA nephropathy and on our Phase III artemis IGAN trial, which has now nearly 120 sites activated worldwide. Interestingly, data from multiple research groups now indicate that the tubular interstitial disease component in IGA nephropathy involves lectin pathway activation on the surface of damaged tubular cells caused by proteinuria and/or ischemia reperfusion injury associated with, for example, acute kidney injury, leading to tubular interstitial inflammation in fibrosis. This evidence further underscores the role of the lectin pathway in IgA. Narsoplimab appears to be the only drug with FDA's Breakthrough therapy designation for IgA nephropathy and the only drug that can obtain full approval on proteinuria data alone, potentially shortening the full approval process by years by not needing to show improvement in EGFR. We think that there are good reasons for these singular distinctions afforded in narsoplimab, and we look forward to seeing and sharing the data. We view narsoplimab as not just a drug but as a platform therapeutic. And we continue to expand the scope of indications that we're targeting for narsoplimab and our other MASP-2 inhibitor programs beyond endothelial injury syndromes and proteinuric renal diseases. MASP-2 and the lectin pathway play a central role in the innate inflammatory response and their importance in driving a long list of diseases and disorders is becoming increasingly recognized and understood. Our long-acting MASP-2 antibody, OMS1029 is expected to be in the clinic in early 2022 and to allow once-monthly or even less frequent subcutaneous dosing. We're hoping to follow that up quickly with our orally available MASP-2 inhibitor. Before moving on to OMIDRIA and other programs in our pipeline, I'll bring you up-to-date on our other complement program, OMS906, our MASP-3 inhibitor. MASP-3 is responsible for the conversion of pro Factor D to Factor D and is thought to be the key activator and premier drug target in the alternative pathway. In September, we began dosing human subjects in a placebo-controlled, double-blind, single ascending dose and multiple ascending dose Phase I clinical trial. The trial is running on schedule. Our first cohort has already completed dosing. The second cohort is being dosed now, and the third and fourth cohorts are enrolling. Initial data readout is expected in the coming year. Data from our OMS906 program were presented last month at the Fourth Complement Based Drug Development Summit, and the presentation can be found on our Investor Relations website. As with our MASP-2 program, we're also moving ahead with the development of orally available small molecules that inhibit MASP-3. OMS906 is a long-acting antibody achieved in part by modifications to its Fc region. To avoid primarily any potential encumbrance to the late-stage clinical or commercial manufacturing of OMS906 at its current manufacturing facility, we recently entered into a licensing agreement with Xencor as have a good number of other companies with antibody therapeutics that have long half lives. We expect that this will entail the payment of modest milestone fees and low to mid-single-digit royalties, while Xencor's patents remain extent in the jurisdiction of sale. In parallel with our MASP-2 and MASP-3 clinical work, a great deal of complement research is being done both in our Seattle facilities and in our labs at the University of Cambridge. Our work has previously resulted in redefining the biology of the complement system. Examples include the C4 bypass mechanism by which MASP-2 directly activates C3 and the role of MASP-3 in activation of the alternative pathway. Our team continues to redefine complement biology, and we plan to publish these new discoveries once we have securely established the corresponding patent positions. So let's turn now to OMIDRIA, our commercial ophthalmic drug product. Net revenues from OMIDRIA in the third quarter were $26.1 million after deducting out $8.7 million return reserve associated with the October 1 expiration of pass-through for OMIDRIA. Had we not booked this return reserve, our Q3 revenues would have been an all-time record high. This was despite the headwinds of COVID-19, which because of the additional safety precautions required in the operating room, continue to affect overall cataract surgery volumes by restricting throughput of cases in the surgical facilities. Our net loss for the quarter was $38.5 million or $0.66 per share, of which $13.6 million or $0.23 per share were noncash charges. Our non-GAAP adjusted net loss for the quarter was $19.9 million or $0.34 per share. This non-GAAP adjusted net loss also conservatively includes the $8.7 million or $0.15 per share deduction from our third quarter revenues for the return reserve. If and when reinstatement of separate payment for OMIDRIA occurs, we expect to recover the $8.7 million reserve. As of September 30, 2020, we had $153.5 million of cash and investments available for general operations. This includes the receipt of net proceeds from our third quarter financing activities. Specifically, $93.7 million from the issuance of 6.9 million shares of stock and an additional $76.9 million from issuing new unsecured convertible debt after repurchasing $150 million of unsecured debt that was previously outstanding. We also purchased a capped call on the new debt that effectively increases the initial conversion price of $18.49 per share to $26.1 per share. This substantially reduces dilution or cash expense in the event of a conversion. We saw some encouraging trends in OMIDRIA sales in the third quarter as well. Despite reportedly longer surgical turnover times and reduced cataract surgery procedural throughput due to COVID protocols in surgical facilities, per facility utilization of OMIDRIA in Q3 increased over Pre-COVID levels. Also, overall units sold progressively increased throughout the quarter. We expect that this momentum will be restored and continue to grow if and when OMIDRIA is granted separate payment. As previously discussed, our extension of pass-through reimbursement for OMIDRIA expired on October 1. The result of that is that OMIDRIA, when used for Medicare Part B beneficiaries, is now reimbursed as part of the ambulatory payment classification for cataract surgery. We have had multiple meetings with CMS and HHS and have made a compelling case based on regulatory law, that CMS must pay separately for OMIDRIA as a non-opioid alternative used during surgery in the ASC setting now that the drug's pass-through status has ended and it is packaged under CMS' outpatient prospective payment system. The criteria for separate payment are strictly objective, and OMIDRIA meets them all. We are optimistic that CMS will comply with its own regulation and provide separate payment for OMIDRIA in the ASC during the fourth quarter of 2020 and throughout calendar year 2021, which subsequently could be further extended. In parallel, a broad coalition led by Voices for Non-opioid Choices and supported by over 50 bipartisan house representatives and over 20 bipartisan senators continues to advocate for the No Pain Act. This bill would extend separate payment in the ASCs and in the hospital outpatient surgery departments for a period of at least 5 years for OMIDRIA and other non-opioid alternatives used during surgery. In addition to strong support from surgical and nursing societies, trade organizations as well as patient advocacy groups and individual practitioners, 2 large and influential societies, the American Medical Association and the American Society of Anesthesiologists have recently endorsed the No Pain Act. An opportunity for enactment of this bill could come during the next session of Congress. You might recall that a peer-reviewed publication in the Journal of Cataract and Refractive Surgery showed that OMIDRIA significantly reduced the need for intraoperative fentanyl, a highly addictive opioid while also reducing patients' pain. Another manuscript demonstrating that OMIDRIA is opioid sparing was recently published in the peer-reviewed journal current medical research and opinion. The study demonstrates that patients who received OMIDRIA during cataract surgery were prescribed fewer postoperative opioid pills than patients who did not receive OMIDRIA. Despite the OMIDRIA-treated group having a greater incidence of preoperative comorbidities and higher risk for surgical complexity. To continue to build validation of the opioid-sparing benefits of OMIDRIA within the published literature, we have partnered with the Cataract Surgery Pain Study Group. The Cataract Surgery Pain Study Group is led by Dr. Terry Kim, president of the American Society of Cataract and Refractive Surgery and Professor of Ophthalmology and Head of the Cornea and refractive Surgery Services at Duke University. Together with other cataract surgery thought leaders from across the nation. The group's mission is to examine the role of non-opioid alternatives like OMIDRIA in cataract surgery. Based on the group's research, multiple publications will likely be generated, adding to the body of literature supporting the role of OMIDRIA in reducing the need for intraoperative and postoperative opioids in cataract surgery. The pain study group's research and publications should further strengthen the case for the separate payment of OMIDRIA by CMS. In the meantime, our commercial team is focusing its OMIDRIA efforts on driving utilization in hospitals across commercially insured patients and NVA facilities. The advocacy and relationships we have in the ophthalmology community remains strong. We have multiple avenues to secure separate payment for OMIDRIA. And we will let them play out. While we are planning for success, we also have established alternative sales strategies. If needed, these can be implemented quickly to ensure that OMIDRIA will be available for the long term and providing value to both patients and our shareholders. Moving on to our phosphodiesterase 7 or PD 7 inhibitor program, OMS527 targets addiction. Our Phase I clinical trial was successful, both with respect to safety and achieving daily oral dosing. While our current clinical focus remains on expanding indications for our MASP-2 and MASP-3 complement franchise, we plan to advance our OMS527 Phase II program pending resource availability. We also continue to see a unique opportunity in targeting GPR174 for cancer immunotherapy. GPR174 is an immunosuppressive G protein coupled receptor, whose activity is intimately linked to the tumor microenvironment. Our recent data with mouse tumor models further validate GPR174 as an important and novel target for enhancing a T cell's capacity for killing cancer cells. We have found that GPR174 deficiency in tumor-specific CD8-positive cytotoxic T cells, increases their activation, resulting in anti-tumor immune responses that markedly reduce tumor growth. Similar to GPR174, the adenosine GPCRS A2A and A2B are also activated by products of the tumor microenvironment. With all 3 receptors, GPR174 A2A and A2B using the same cyclic AMP signaling pathway. Our ongoing in-vitro signaling experiments continue to reveal that inhibition of all 3 receptors synergistically enhances T cell activity. So we believe that new and more effective cancer immunotherapy approaches will involve GPR174 inhibitors alone or in combination with adenosine receptor inhibitors. Motivated by this understanding, we are aggressively developing both small molecule and antibody inhibitors of GPR174. Our team continues to make discoveries around the GPR174 program, and we plan to make those public after filing additional patent protection. With that, I'll turn the call over to Mike for an overview of our third quarter financial results. Mike?
