Thank you, Shari, and thank you all for joining our call this morning. Let me begin by saying that the third quarter's momentum continues as we speak today. In both the oncology and sickle cell programs, we're making progress on two key objectives. First, to complete enrollment of our Phase 3 trial of uproleselan in the second half of next year; and second, following on encouraging additional analysis of the RESET study data and return of our rights to work in sickle cell disease, to identify whether there's an opportunity for GlycoMimetics to move ahead to develop the therapy to treat acute vaso-occlusive crisis or VOC in sickle cell disease. I'll begin with the uproleselan program. Enrollment in the company-sponsored pivotal Phase 3 trial, evaluating uproleselan in patients with relapsed refractory acute myeloid leukemia or AML continues according to plan. After a slowdown at most of our sites in the earliest stages of the pandemic, the pace of enrollments of the trial has returned to forecasted levels. As a result we're maintaining our prior guidance, we expect to complete enrollment in the second half of 2021. In our collaboration with the National Cancer Institute or NCI, enrollment in that Phase 3 pivotal trial has also recovered after an initial slowdown due to the pandemic. Their focus is treating a newly diagnosed AML patient who is fit for intensive chemotherapy in 60 years of age or older. Enthusiasm for both of these trials continues to be strong, highlighting uproleselan's potential to provide benefits across several clinical endpoints, including improving chemotherapy outcome such as depth or duration of remission and overall survival and ameliorating some of the serious adverse events of intensive cytotoxic chemotherapy. As we said before, we believe, our data supports our vision of uproleselan as a foundational treatment for AML across the spectrum of patients and as a key element of a variety of therapeutic regimens. To that end, at the Society of Hematologic Oncology in September 2020, our collaborators at MD Anderson Cancer Center, presented statistically significant preclinical data pointing to the potential for combination of uproleselan with venetoclax and HMA in AML to prolong survival. This was demonstrated in a xenograft model derived from the patient resistant to venetoclax and HMA treatment alone. The potential important to this data set was underscored earlier this week, when we announced it was also accepted for oral presentation at the upcoming December Annual Meeting of the American Society of Hematology or ASH. Clinical investigators have recognized the significance of this data given the relatively short duration of response to venetoclax combination therapy in this patient population. We're currently exploring options to take this combination forward in the clinic. In sickle cell disease, emerging data from the Phase 3 RESET trial continue to highlight the importance of early intervention with fast acting E-selectin antagonists that disrupt the underlying inflammatory mechanisms driving acute vaso-occlusive crisis. Our additional analyses of data from the RESET trial are providing valuable new perspective to us in our E-selectin programs, primarily in support of the clinical benefit that can potentially be achieved by administering our target E-selectin in product candidates early in acute VOC. We presented findings at multiple sickle cell focused meetings and conferences. And at upcoming ASH meeting, we plan to recap two secondary endpoints subgroup and subset data. We believe these data provide a clear biologic and clinical foundation for treatments within E-selectin antagonist in acute VOC. The FDA recently granted rivipansel a rare pediatric disease designation for the treatment of sickle cell disease in patients under 18 years of age, which recognizes a significant need for pediatric patients. Should development of rivipansel in the pediatric setting advance, this designation could provide us with a Priority Review Voucher. As we continue to roll out data from our completed post-hoc analysis of the RESET trial, analyze new data from the open-label extension study, and continue to engage with the FDA, it remains premature to provide any guidance as to whether we will take the rivipansel program forward. The therapeutic options available for patients with sickle cell disease have increased substantially with patient approval. Even with these approved drugs however, the acute pain crisis of sickle cell disease remain an area of high unmet need. And to our knowledge, there are no other late-stage therapies in development focused on acute pain crisis for adult and pediatric patients. As we continue to refine our analysis and improve our understanding of fast-acting E-selectin antagonism our options if any will become more clear. We're actively exploring all opportunities, including options with GMI-1687. With regard to GMI-1687, it's a more potent and more specific E-selectin antagonist in rivipansel and importantly by available following subcutaneous administration. As such, we believe, this product candidate may be ideally suited for treatment of acute VOC in the outpatient setting, potentially even providing patients with the opportunity to treat themselves at home in the early stages of VOC. We have received multiple invitations to give oral presentations at key sickle cell and Hematology Conferences in GMI-1687 with the highlights of which I'll share after Helen's comments. Finally, I'd like to leave you with my thoughts in the remainder of the year as well as 2021. End of 2020 we will be data rich with multiple oral presentations and posters at ASH, covering GlycoMimetics four compounds, uproleselan, rivipansel, GMI-1687, and GMI-1359, and all will have three oral presentations and two poster presentations, which is a testament to the strength, novelty and relevance of our data. Within the coming year, we anticipate the completion of enrollment in our Phase 3 rivipansel trial in relapsed refractory AML. This will clearly be an important milestone for this potentially foundational therapy. If realized, our success in the relapsed refractory patient population could herald the arrival of a new treatment option for patients with AML. In addition, as enrollment continues in our Phase 1b trial with GMI-1359 in patients with advanced breast cancer, we hope to share our findings in the first half of 2021. We will present preclinical data at ASH in December to highlight the importance of the biological activity demonstrated by targeting CXCR4 and E-selectin with that molecule. Importantly, as we've always operated on a lean and focused budget, we have cash to get through these milestones. And now I'd like to ask Helen to comment on the data we presented at the September meeting at the Foundation for Sickle Cell Disease Research or FSCDR, Annual Scientific Conference on Sickle Cell and Thalassaemia or ASCAT meeting in October, and the data accepted for oral presentation at ASH.
