Thank you, Jim and good morning everyone, and thank you for joining us today. It is a pleasure to provide an update on Curis and our progress in developing multiple innovative drug candidates for patients with cancer, including our two clinical programs; CA170 and CUDC-907. First I would like to update you on CA170. CA170 is the first orally administered small molecule immune checkpoint antagonist to enter the clinic. Recall that CA170 was discovered in our collaboration with Aurigene it targets PD ligands and VISTA immune checkpoint. The PD ligands such as PDL-1 and PDL-2 and VISTA are members of the same family, the B7 immunoglobulin super-family of immune-regulators that share structural similarity in their extra-cellular domain. And this extra-cellular domain of these proteins is where CA170 is designed to bind. We have shown that CA170 selectively rescues T-cell proliferation and function that are specifically inhibited by the PD ligands or VISTA. Our goal is to develop CA170 as a cancer immunotherapy and in this regard developed as the first orally early administered anti-checkpoint therapy for cancer patients. As now multiple anti-checkpoint immunotherapies are either approved for in development, but so far all of these are antibodies that need to be administered intravenously in an infusion clinic setting. We believe CA170 can establish a new class of immunooncology anti-immune checkpoint therapy that is administered as an oral pill. As a small molecule rather than an antibody we expect that the pharmacokinetic properties of CA170 will likely provide an advantage in the dosing flexibility as a monotherapy. And perhaps even more importantly, when used in combination with other anti-cancer treatment regimens. We believe that a successful CA170 can provide a compelling treatment alternative for patients and physicians. We are pleased to note that in June the FDA accepted our IND application for CA170 and shortly thereafter the first patient with cancer was dosed in the phase 1 trial of CA170. In this phase 1 study, CA170 is administered as an oral capsule once daily in a continuous manner. Our main objective during the dose escalation stage of the trial is to establish CA170's safety, to characterize its pharmacokinetic profile, to demonstrate potential markers of immunomodulation and to assess any clinical activity in patients with solid tumors and lymphoma. To accelerate the dose escalations stage, we are enrolling patients with any type of cancer and are not requiring specific biomarkers such as the expression of specific checkpoint targets on patient tumor biopsies as criteria for enrollment. The dose escalation stage will enroll patients who may have been previously treated, as well as patients that are naïve to anti-checkpoint immunotherapy. The dose escalation enrolls patients in the U.S. Centers only, currently. Our goal with the dose escalation stage of this phase 1 trial is to establish the recommended dose and schedule for CA170 administration which will be used in the expansion stage of the study and future studies of CA170. Now in the expansion stage of the trial we expect to narrow patient enrollment to specific cancer types. We also expect to employ potential patient selection strategies such as the expression of CA170's molecular targets on patient tumor samples. In the expansion stage, although we intend to primarily focus enrollments to patients who are naïve to anti-checkpoint immunotherapy treatment, we also expect to continue exploring CA170 in previously treated patients because CA170 targets both, the PD ligands, as well as the VISTA checkpoint. For enrollment checkpoint immunotherapy naïve patients in the expansion stage of the trial, we expect to enroll patients in the U.S. as well as in multiple centers outside of the U.S., predominantly in Europe and in Asia. Our aim with the expansion stage is to identify the initial indication and the regulatory path to potential approval for this highly differentiated drug candidate. Now I'd like to turn the discussion to CUDC-907 which is being investigated in a phase 2 trial in patients with relapsed refractory diffuse large B-cell lymphoma or DLBCL. As you know CUDC-907 was discovered by Curis scientists and is an oral small molecule drug candidate designed to target the HDOC NPI-3 kinase enzymes. In its phase 1 trial CUDC-907 treatment has resulted in multiple objective responses including complete responses in patients with DLBCL. The objective of our ongoing phase 2 study is to assess CUDC-907 efficacy and specifically in the patient population with DLBCL whose tumors have mixed alterations. Should they be positive, we intend to use the results of this ongoing phase 2 trial for potential accelerated approval of CUDC-907 in this cancer indication. In the open label phase 2 trial, we expect to enroll upto 60% patients with relapse refractory DLBCL who will be treated with CUDC-907 monotherapy at the recommended phase 2 dose. The recommended phase 2 dose was established to be 60 milligram once daily using its schedule of five days on and two days off treatment in a continuous manner. Multiple centers in the U.S. are actively enrolling patients in this trial and we expect to initiate enrollment of patients at centers in Europe later this year. The primary endpoint of the study is objective response rate with secondary endpoints as durable of benefits including duration of response, progression fee survival, and overall survival. Pending the outcome of this study, we believe that the study designed can permit us to discuss the results with the FDA as a potential path for accelerated approval of CUDC-907 monotherapy in this patient population. Also in June 2016, updated data from the phase 1 trial of CUDC-907 were presented at the European Hematology Associations Annual Meeting held in Copenhagen, Denmark. The updated assessment from a total of 31 patients with relapsed refractory DLBCL showed that among the 21 response valuable patient's objectives responses were reported in 9 patients including three patients with complete responses. A retrospective post-hoc analysis showed that among six of these response valuable DLBCL patients whose tumors had make alterations five experienced objective responses including the three patients with complete response. Importantly, all five of these responding patients' tumors also had BCL-2 alterations. We are also continuing with the enrollment of patients with solid tumors in the separate phase 1 trial of CUDC-907 in order to assess its safety and preliminary anti-cancer activity. Thus far no additional safety signals have been observed in this study beyond what has been noted previously in patients with the hematologic malignancy. We have recently limited enrollment in the trial to patients whose tumor have alterations. The objective of this study is to explore the potential to expand the use of CUDC-907 for treatment of patients with MYC altered solid tumors. Finally, I'll turn it to Erivedge which is commercialized globally by our collaboration partners Genentech and Roche for the treatment of advanced basal cell carcinoma. We are pleased to note that in June 2016 Roche presented data from two trials of Erivedge at the ASCO Annual Meeting. One of these studies showed that the safety profile of Erivedge continues to be consistent with the previously reported safety profile. And a second presentation risk reported results of a trial demonstrating that intermittent dosing schedules of Erivedge may be an option for patients with multiple basal cell carcinoma to drive long-term benefit. With that I will now turn the call over to Jim Dentzer for discussion of our financial results. Jim? James Dentzer Thank you, Ali. For the quarter ended June 30, 2016, we reported a net loss of $11.3 million or $0.09 per basic and diluted share as compared to a net loss of $8.1 million or $0.06 for basic and diluted share for the same prior year period. Revenues were $1.7 million and $2.1 million for the second quarter of 2016 and 2015 respectively. Revenues for both periods comprised primarily royalty revenues recorded on Genentech and Roche's net sales of Erivedge. Operating expenses were $12.4 million for the second quarter of 2016 as compared to $9.5 million for the same period in 2015. Research and development expenses were $8.8 million for the second quarter of 2016 as compared to $5.9 million for the same period in 2015. The increase in research and development expense was primarily due to increased direct spending over the prior year period related to outside services supporting the ongoing clinical activities of CUDC-907 including initial costs for the Phase II trial that was initiated in January 2016 and direct costs for programs under the Aurigene collaboration including initial costs for the CA170 Phase I trial and initiated June 2016 and a $3 million milestone payment upon the FDA acceptance of our CA170 IND. Finally, employee-related expenses increased over the prior year primarily due to additional headcount. General and administrative expenses remained unchanged at $3.4 million for the second quarter of 2016 as compared to the same period in 2015. Other expense was $0.6 million for the second quarter of 2016 as compared to $0.8 million for the same period in 2015. Other expense for both periods primarily consisted of interest expense related to the loan made by BioPharma II to Curis Royalty, a wholly owned subsidiary of Curis. As of June 30, 2016, Curis' cash, cash equivalents, marketable securities and investments totaled $61.7 million and there were approximately 129.5 million shares of common stock outstanding. With that, we'll open the call for questions.
