Thank you, Mani, and thank you to the conference call and webcast participants for joining us this morning. We continued to develop the organization and streamline our efforts to build Curis into an oncology focussed company with strategic emphasis on development and eventual commercialisation of innovative and effective drugs for cancer patients. Let me begin this morning with our most advanced molecule CUDC-907 which is an oral Dual HDAC and PI3 Kinase Inhibitor that is being studied in patients with relapsed refractory aggressive lymphomas and separately in patients with certain solid tumors. We are very pleased with the progress being made with CUDC-907 especially in the setting of relapsed refractory Diffuse Large B-cell lymphoma or DLBCL. In the past quarter, we reported results from the ongoing Phase 1 trial of CUDC-907 at the ASCO Annual Meeting and the European Haematology Association Annual Meeting as well as the presentation at the International Congress on Malignant Lymphoma that was held in Lugano, Switzerland. Now these presentations highlighted that six out of the ten responsive evaluable heavily pre-treated patients with relapse refractory DLBCL experienced objective responses including two patients with complete responses and four patients with partial responses, while two out of the ten patients had stable disease. Three of these objective responses is which included one complete response and two partial responses occurred in patients with transformed follicular lymphoma DLBCL, one complete response was observed in a patient with GCB subtype of DLBCL and two partial responses in patients with unclassified DLBCL. Additionally, one patient with Hodgkin's lymphoma also experienced a partial response. Overall, stable disease was reported in 25 of the 44 response evaluable patients with various lymphomas or patients with multiple myeloma. No new dose limiting toxicities or DLTs were identified and adverse events were consistent with our previous reports and were most commonly occurring drug related side effects of diarrhoea, fatigue, nausea, thrombocytopenia and some neutrophil decreases most of which appeared to mechanism related. Based on pharmacokinetic analysis, CUDC-907 appeared to have readily and predominantly distribute to patient tissues including the tumor tissue with a high resident half life which may afford exposing the tumor to significantly high concentrations of potent HDAC and PI3 kinase inhibitor reactivity. We believe this property of CUDC-907 may uniquely contribute to its clinical activity in the population of patients with DLBCL and it also serves as the basis for our ongoing trial of CUDC-907 for treatment of patients with certain solid tumors. We are currently continuing to enrol patients with DLBCL in expansion cohorts of the Phase 1 study where CUDC-907 is administered either as a monotherapy or in combination with rituximab. We are also in the process of finalizing the design of a Phase 2 registration directed trial for CUDC-907 in relapsed refractory DLBCL setting which we expect to imitate in the fourth quarter of this year. We expect to define and enrol a subset of patients in this study with DLBCL based on the genetic background of their disease and are now determining the regulatory path with regards to monotherapy and/or a combination treatment opportunities. We are currently in active discussions with our key investigators and advisors for the upcoming trial and expect to hold discussions with the regulatory authorities regarding our data, our designs and plans for CUDC-907. In addition to the ongoing study in the hematologic malignancy setting, we continue to enrol patients in the second Phase 1 trial testing CUDC-907 in patients with relapsed or advanced solid tumours. Based on insights from our lymphoma study we are exploring the potential modification of this trial to apply a patient enrichment strategies based on similar genetic alterations in solid tumors including the not midline carcinoma setting. We look forward to provide further update from this solid tumor study during this year as well. I’d now like to update on our collaboration with Aurigene. Since the announcement of our agreement earlier this year, we have continued to build a strong and interactive partnership with our colleagues at Aurigene. Both Curis and Aurigene teams are fully aligned and engaged with advancing molecules from multiple programs into the clinic and we expect to exercise options under this collaboration to exclusively license drug candidates in the very near future to initiate their clinical development. We believe immuno-oncology is one of the most exciting treatment approaches that has emerged in the field of cancer therapy which is based on the strategy of employing and activating the immune system against the patients tumor. Our colleague and scientist at Aurigene had been successful at generating small molecules that can be administered orally in order to target and disrupt immune checkpoint receptor ligand interactions including the PD-1, PD-L1 interactions and result in activation of T-cells and anti-tumor activity in the preclinical setting. And these results are similar to that achieved with anti body molecules directed at the same targets. To our knowledge these represent the first and currently only in the class of oral small molecules targeting immune checkpoint receptor ligand interactions. As we had stated previously, our collaboration with Aurigene is a multiyear partnership expected to generate a steady pipeline of novel drug candidates in the coming years. At the time of entering into the collaboration we selected an oral small molecule PD-1 antagonist which was designed to disrupt PD-1, PD-L1 interactions and activate T-cells for cancer immunotherapy. In addition to this PD-L1 antagonist program during the second quarter we also selected a second small molecule immuno-oncology program to advance it further in preclinical developments to support its potential IND filing in clinical development as well. Our partner Aurigene continues to make significant progress in advancing the current two immuno-oncology programs in preclinical development while they are continuing their efforts to address additional immune checkpoint targets with small molecule antagonist. We expect to present preclinical data and results from the immuno-oncology programs at scientific meetings later this year. And we continue to expect to exercise our option to exclusively license and file an IND for one of these molecules later this year. We are also pleased to report that Aurigene has made significant progress in our IRAK4 kinase inhibitor program. During the second quarter, Aurigene presented preclinical data from the IRAK4 program at the American Association for cancer research or AACR Annual Meeting, where it showed a series of potential IRAC4 inhibitors that demonstrated potent anti tumor activity in cell based as well as in in vivo tumor models with activating MYD88 mutations. In addition to the cancer models, some of these compounds also showed activity in in vivo models of information indicating the potential of targeting IRAC4 in both oncology and inflammatory disease settings. We expect to exercise our option to exclusively license an IRAC4 inhibitor development candidate in the near future and file an IND application during the first half of next year for clinical development of that compound in specific haematological malignancies. We strongly believe that our collaboration with Aurigene is a unique example of coming together of two organizations with the goal of aligning complimentary expertise to expedite development of promising molecules in the field of cancer therapeutics. We are each committed to bringing considerable resources in this competitive field and intend to do this in a cost effective manner. We continue to grow internally as a developmental organisation on multiple fronts including project leadership, clinical development and clinical operations, project management, regulatory data management and translational medicine. Now our programs CUDC-907, the immuno-oncology drug candidates and our IRAC4 inhibitor remain our focus and they represent our efforts to transform Curis into a development and eventually commercialisation focus business. I would now like to turn to Erivedge which is being developed and commercialised globally by Genentech and Roche under our collaboration. Roche continues to concentrate on the global commercialization of Erivedge for the treatment of advanced BCC in key territories worldwide. In this regard, we recorded royalty revenues of approximately $2 million for the first quarter this year and as compared to $1.8 million for the second quarter of 2014. Approximately 69% of Erivedge net sales for the first half of 2015 were derived in the U.S. with the remaining sales being generated outside of the U.S. With regards to its development, Roche and Genentech continue with multiple trials for testing Erivedge in earlier settings of basal cell carcinoma. Outside of oncology, Roche continues to indicate an interest in investigating Erivedge in idiopathic pulmonary fibrosis disease. In June of 2014, Roche filed an IND application with the FDA to initiate a multi center Phase 2 clinical study of Erivedge in patients with IPF. After the Phase 2 study opened but prior to patient enrolment Roche suspended the study in August in order to amend the protocol to incorporate Esbriet or pirfenidone, the new standard of care for IPF into the trial design. Roche has stated that the first patient in this study is pending in anticipation of trial design amendment to incorporate the new standard of care, Esbriet. I would now like to turn the call over to Mike Gray our Chief Financial Officer and Chief Business Officer for his discussion of our financial results after which we will open the call for Q&A. Thank you.
