Thank you, Bill. Good afternoon everyone and thank you for joining us today. 2019 was a formative year for Curis. We reported promising clinical data in our CA-4948 program, laying the groundwork for important expansion and further progress in 2020. We retooled our approach to addressing a meaningful oncologic target, VISTA, with the addition of our CI-8993 to our portfolio. And we established valuable partnerships that position Curis for sustained momentum well into the future. As many of you are acutely aware, the evolving COVID-19 pandemic presents unprecedented challenges to people across the globe. It has also brought to the forefront the importance and necessity of medical innovation. At Curis, we are dedicated more than ever to our mission of bringing our targeted cancer therapies to patients. We are closely monitoring developments related to COVID-19 and we remain focused on running our business as efficiently and seamlessly as we can. Now, let's jump into our clinical development programs for next-generation targeted cancer drugs. I'd like to start with our IRAK4 program. At the ASH Conference in December, we reported exciting preliminary data from our ongoing Phase I dose escalation study of CA-4948 an IRAK4 kinase inhibitor for the treatment of patients with relapsed or refractory non-Hodgkin's lymphoma, including patients with DLBCL, Waldenström's macroglobulinemia, and Oncogenic MYD88 mutation. These data provided the first ever evidence that targeting IRAK4 in this patient population results in anti-cancer activity and underscore the potential for CA-4948 to serve as a novel therapeutic option for these patients. The study is still ongoing. But we were pleased to report at ASH that the study has advanced into the therapeutic dose range. At dose levels of 200 milligrams twice daily and higher, five of six evaluable patients experienced a reduction in tumor burden. The mean reduction in these patients was 29%. One of these patients, a patient with Waldenström's, provided a really nice single patient example of the strong dose response we are observing in the study. This patient enrolled in the study at 50 milligrams twice daily. And was dose escalated to 100 milligrams twice daily, then escalated again to 200 milligrams twice daily. With each increase in dose, this patient is seeing further reduction in tumor burden. That this patient's individual dose response is consistent with the overall dose response seen with the group as a whole is very exciting. We are currently evaluating patients at the 300-milligram twice daily dose, and we will continue to dose escalate until the maximum tolerated dose and/or the recommended Phase 2 dose is determined. We expect to provide updated safety and efficacy data from this study later this year. Also at the ASH Conference in December, data were presented that highlighted CA-4948 as a potential therapy to treat patients with AML/MDS or acute myeloid leukemia or myelodysplastic syndrome, who have spliceosome mutation that cause the oncogenic long-form of IRAK4, a direct target of CA-4948. We plan to initiate this study in the first half of 2020. In short, this year is shaping up to be a busy one for CA-4948, and we are looking forward to updated efficacy data and we are excited to explore the clinical potential of CA-4948 in patients with AML/MDS and certain spliceosome mutation. Moving to our fimepinostat program, we announced earlier today that we are discontinuing our Phase 1 combination study of fimepinostat and venetoclax. Although we did not observe any drug-drug interaction from the combination, we also did not see an efficacy signal that would warrant advancing this combination to the next stage of development. Given current market conditions as a result of the COVID-19 pandemic, we have decided to focus our resources on CA-4948 and CI-8993. Ongoing analytical research with DarwinHealth to characterize biomarkers and tumor subtype alignment will help guide any future clinical development opportunities with fimepinostat. Our clinical progress in 2019 has been complemented by recent advancements on the corporate side of our business. Over the past few months, we have initiated multiple partnerships and collaborations that we believe position Curis well for the longer term. In February of this year, we amended our collaboration agreement with our partner, Aurigene, for the development and commercialization of CA-170, an orally available dual inhibitor of VISTA and PDL1. This amendment enables Aurigene to fund and conduct a large Phase 2b/3 randomized study of CA-170 in combination with chemo radiation in patients with non-squamous, non-small cell lung cancer. In return, Aurigene receives rights to develop and commercialize CA-170 in Asia, in addition to its existing rights in India and Russia. Curis will be entitled to receive royalty payments on future sales of CA-170 in Asia, while maintaining full commercial rights to CA-170 in the U.S., EU, and the rest of the world outside of Asia. This update to our collaboration agreement allows us to support the clinical advancement of CA-170, while leveraging Aurigene's expertise and resources for CA-170 late-stage development. We continue to believe that VISTA is a meaningful target in the cancer setting. In January of this year, we entered into an option and license agreement with ImmuNext for the development and commercialization of anti-VISTA antibody, including its lead compound, CI-8993, a clinical stage monoclonal antibody designed to antagonize the VISTA signaling pathway. We are particularly excited by the prospect of this partnership as it provides us another opportunity to pursue the VISTA pathway for the treatment of cancer. We hope to leverage our experiences from CA-170 to support the development of CI-8993 and plan to initiate a Phase 1a/1b dose escalation study of CI-8993 later this year. Also in January, we announced a scientific collaboration with DarwinHealth to characterize biomarkers and tumor subtype alignments for fimepinostat. We believe this collaboration will deepen our understanding of the MIC mechanism and potentially identify any future development opportunities for fimepinostat. Lastly, I want to touch on the $30 million transaction with Aspire Capital that we announced in February. Bill will walk through the details, but at a high level, this deal gives us an efficient and flexible capital source from a long-term health care-focused institution to support the clinical development of our candidate. We are pleased to extend our cash runway with this transaction as we have an important year ahead of us. I'll now turn the call over to Bill for a summary of our financial results for the year and fourth quarter. Bill?
