Thank you, Jim. Good morning, everyone, and thank you for joining us today. As we move into the second quarter of the year, we are excited about the depth of our clinical pipeline. This is the first time for Curis to have three drug candidates in clinical development, which reflects the evolution and strategy of our organization. Our achievements in the first quarter included preparation of a pivotal study of CUDC-907 in patients with relapsed or refractory DLBCL, which tumors have MYC-alteration. This is a population with no durable treatment options. Secondly, testing of CA-170, our small molecule PDL1 and VISTA checkpoint inhibitor in patients at higher dose levels and using twice-daily dosing in our Phase 1 trial as well as our collaborator Aurigene enrolling patients at sites in India in the Phase 2 trial. Thirdly, initiation of enrollment and dosing in patients with lymphomas for our IRAK4 inhibitor CA-4948, the first such drug candidate to examine patients with cancer. And finally completing IND enabling studies of CA-327, our small molecule PDL1 and TIM3 antagonist in preparation for regulatory filing. These achievements show our progress towards our goal which is developing new oncology therapeutics that improve treatment options and bringing these therapeutics to patients with our own capabilities. Today I will provide a brief update on each of our pipeline programs. Our most advanced clinical candidate previously known as CUDC-907 and now designated from the fimepinostat, have shown significant clinical benefit in patients with relapsed refractory DLBCL with MYC-alteration. Thus far based on treating a total of 105 patients with relapsed refractory DLBCL who were not transplant eligible, treatment with fimepinostat have resulted in 19 objective responses, 9 of which were complete responses. The majority of these responses, 14 of them were among the 60 patients whose tumors were identified to have MYC-alterations. Furthermore, the median duration of response for the patients treated with fimepinostat was 14 months. We believe this level of monotherapy benefit in this patient population is significant and we are continuing our discussions with regulatory agencies and working to initiate a pivotal study based on the results of which we'd expect to secure registration of fimepinostat for this population of patients with DLBCL. In parallel, we continue to work with our commercial manufacturers and potential providers of an appropriate companion diagnostic. We expect to provide a more detailed update on the development path and plan for fimepinostat before the end of this quarter. Our second clinical candidate CA-170 is the first orally administered small molecule checkpoint antagonist to enter clinical development, which we are developing in collaboration with our partner Aurigene. CA-170 is a dual inhibitor targeting the PDL1 [indiscernible] as well as the VISTA inhibitory immune checkpoint. In our ongoing Phase 1 trial CA-170 have had a good safety profile, while evidence of potent immune modulation and patient tumor shrinkages have been observed at doses up to 800 milligram administered once-daily. The trial continues to investigate increasing dose levels and twice-daily oral administration to maximize patient drug exposure. Our partner Aurigene also continues with enrollment in a Phase 2 trial of CA-170 in patient -- patients with selected cancer types in multiple centers in India. This Phase 2 study is providing access to a significant population of patients who have not experienced prior immunotherapy or expensive prior anticancer treatment. Enrollment in these trials is progressing according to our expectations and we plan to provide additional updates from CA-170 studies by mid-year 2018. Our third clinical candidate CA-4948 is currently the only IRAK4 kinase inhibitor in clinical development for treatment of patients with cancer. We recently announced the initiation of a Phase 1 trial enrolling patients with non-Hodgkin's lymphoma clearing the dose escalation stage, and in particular those patients with cancers that have a prevalence of alterations in the MYD88 gene or the Toll-like receptor signaling pathway. The aim of this -- the aims of this study are to establish safety and tolerability of CA-4948, to determine the pharmacokinetic and pharmacodynamic profile for the drug candidate, to establish the recommended Phase 2 dose and to measure any anticancer activity in treated patients. We continue to enroll patients and expect to provide an update in the second-half of 2018 for this drug candidate. In summary, in the first quarter of 2018, we saw progress in each of our clinical programs we are excited by the potential of fimepinostat to address the evident needs for patients with MYC-altered DLBCL, and look forward to providing this treatment option to patients and treating physicians. Our clinical studies as well as the trial being conducted by our partner Aurigene continue to enroll patients and we look forward to providing further updates throughout the year. With that, I will turn the call over to Jim for a discussion of our financial results now.
