Thank you, Jim, and good morning, everyone, and thank you for joining us today. The past quarter at Curis was marked by multiple achievements in advancing our drug candidates, as well as extending our capital runway. And today, I’d like to enumerate these and then provide a brief update on each of them. First, we succeeded in filing and the FDA has now accepted our IND application for our third drug candidates CA-4948 to enter the clinic soon. CA-4948, as you know, is an oral small molecule inhibitor of the IRAK4 kinase, which we intend to test in patients with non-Hodgkin’s lymphoma and specifically those that harbor mutations in the MYD88 gene. Second, we presented initial dose escalation results from the Phase 1 trial of CA-170 at the ESMO International Conference and are currently continuing with the trial in multiple countries for this oral small molecule inhibitor of PD-L1 and VISTA immune checkpoints. Third, we have closely examined the results of the Phase 2 trial of CUDC-907 in patients with MYC-altered DLBCL and are preparing for discussions with the FDA regarding these results. Fourth, we secured sufficient cap sold through an equity financing to extend our cash runway well into 2019. These accomplishments are consistent with our business plan to develop multiple oncology drug candidates, which we expect to commercialize in certain territories should they reach the registration state. I would like to begin with an update on CA-170, the first orally administered small molecule checkpoint antagonist in our collaboration with our partner Aurigene. CA-170 targets the PD ligands and the VISTA inhibitory immune checkpoints. We presented initial results from 21 evaluable patients treated as part of the dose escalation stage in the Phase 1 trial of CA-170 with doses ranging from the initial 50 milligram through 800 milligram once daily continuous dose cohort at the ESMO Conference. At the time of the presentation, four patients, including one immunotherapy treatment naïve patients with melanoma had continued shrinkage of their tumors over multiple cycles. We also noted evidence of an increase in the population of cytotoxic T cells within the patients tumors after CA-170 treatment, which is consistent with an immunomodulatory effect of the drug candidate. The safety profile during those escalation has been good with no dose limiting toxicities observed thus far that prevent us from continued escalation. Therefore, we are continuing the dose escalation stage with a cohort at the 1,200 milligram once daily dose. We also plan to present an update from this ongoing Phase 1 trial at the Society of Immunotherapy of Cancer or SITC Conference later this week. In collaboration with our partner, they also expect to initiate a Phase 2 trial of CA-170 enrolling select populations of patients in multiple centers in India, and we will provide further update on this trial upon its initiation. I would now like to provide an update on CUDC-907, which is being investigated as a monotherapy treatment in a Phase 2 trial in patients with relapsed or refractory MYC-altered diffuse large B-cell lymphoma or DLBCL. Although in the front-line setting, some patients with DLBCL have a long-term benefit from R-CHOP standard of care treatment. Patients with relapsed or refractory disease have few options to salvage a cure. The population of these patients with MYC-altered disease appear to have a poor prognosis on second-line treatment and even after stem cell transplants for curative purposes. This is a clear unmet need and is also the same population that appears to benefit the most from CUDC-907 treatment. Overall, in the Phase 1 and Phase 2 trial of CUDC-907, we have observed nine patients with MYC-altered relapsed or refractory disease that benefit with a durable complete response. Given the importance of complete and durable responses in this population of patients, we are currently preparing to discuss these results with the FDA and planning for further development of CUDC-907 in this indication. We also expect to present these results at the upcoming ASH Conference in December. I would now like to update on our IRAK4 kinase inhibitor drug candidate CA-4948. IRAK4 kinase pathway is altered in human cancers as evidenced by the high rate of activating mutations in the MYD88 gene in a number of different hematologic malignancies. We have previously presented non-clinical data, which showed that CA-4948 is a potent inhibitor of IRAK4, in biochemical assays, potently inhibits toll-like receptor signaling in cell-based assays, and results in significant anti-tumor activity in vivo animal models of MYD88 altered diffuse large B-cell lymphomas. During the past quarter, we filed an IND application with the FDA, which has now been accepted and we expect to begin patient enrollment in this Phase 1 trial during this quarter. This study will enroll patients with non-Hodgkin’s lymphoma during the dose escalation, and in particular, patients with cancers that are shown to have alterations in the MYD88 gene or TLR pathway. We plan to provide further updates on this trial with its initiation. Our initial non-clinical data also showed encouraging effects of CA-4948 in models of Acute Myeloid Leukemia and MDS disease. We plan to evaluate the merits of clinical testing of CA-4948 for treatment of patients with these heme malignancies in 2018. Regarding our drug candidate, CA-327 in partnership with Aurigene, which is an orally bioavailable small molecule that targets PDL1 and TIM3 immune checkpoints, IND enabling studies for CA-327 are nearing completion and we expect to prepare for regulatory filing for CA-327 in the first-half of 2018. Lastly, we’re very pleased to note Roche and Genentech’s continued commitment to commercialize Erivedge globally for the treatment of patients with advanced basal cell carcinoma. And with that, I will turn the call over to Jim for a discussion of our financial results.
