Good morning and thank you for joining us for our quarterly update. As you will see in the next few minutes, we have had a very productive several years, including the substantial progress we made in the past several months. These have been in our clinical programs, as well as the substantial number of new discoveries which are about to enter the clinic. I will speak about these in more detail, but in summary we have made a conscious decision several years ago to pursue two antibodies, which have become the backbone of immuno-oncology cancer treatment today. These are antibodies that target PD-1 and CTLA-4. We have advanced them into the clinic individually and in combinations. So far we have treated 100 patients and observed a number of responses, which will be presented at ASCO this year. We believe these backbone molecules are critically important and we plan on pursuing combinations of them, including with one another to achieve regulatory approvals. But we also believe they will play an important role in combinations with our portfolio of novel antibodies, neoantigen vaccines, and cell therapies. How we have accomplished what we have thus far, innovation and speed are the basis of our immuno-oncology business model with five INDs filed over the past 18 months, six INDs on track to be filed this year, and two additional INDs planned in the first half of next year. Our IND roster for this year includes bispecific antibodies that modify the tumor microenvironment in order to make the tumor more susceptible to immune attack. Tumor microenvironment modifiers are amongst the most desirable next gen immuno-oncology approaches. We have at least two antibodies with uniquely desirable properties. In addition to the INDs I mentioned, we expect our cell therapy company AgenTus to also file its first IND for cell therapy next year. Next, I will provide a partnership update, while I don't have an announceable development just yet, discussions are advancing with various companies. These discussions range from several product licensing deals to potentially much larger collaborations. Our expectations are to bring them to closure within the next two to three months. With respect to progress with existing partnership programs with Incyte and Merck all are advancing and we expect additional milestone payments including some that will be payable this year. Also our QS-21 stimulant has received increasing interest as the most potent adjuvant available to date. QS-21 is also an enabling component of our neo-antigen cancer vaccine program, which will be entering the clinic in combination with our own checkpoint antibodies very soon. As you're aware, QS-21 is a key component in the world's most efficacious shingles vaccine called Shingrix, with over 97% efficacy. Shingrix received approval at the end of last year, and this year's revenue estimates have recently been revised to three times what they were earlier in the year. GSK's first full year revenues of Shingrix is expected to top $600 million this year, which is about the same as Merck's Zostavax it was tracking last year about the same after 15 years in the market. Our royalty transaction announced earlier this year has additional revenue milestone payments totaling $40 million, which are due to Agenus if specific revenue milestones are achieved. Now I will provide you with an update on our clinical and research programs. Last year, we launched combination clinical trials of our proprietary CTLA-4 targeting antibody AGEN-1884 with our own PD-1 targeting antibody AGEN-2034. To- date, we have treated as I said more than 100 patients with our CTLA-4 and PD-1 antibodies separately and in combinations. We presented compelling data under pharmacodynamic activity of our anti-CTLA-4 and anti-PD-1 antibodies at AACR recently. As I mentioned earlier, at ASCO this year, there will be clinical data presented on both of these antibodies. In our trials with both compounds, we have seen partial and complete responses as I mentioned in patient with advanced cancers. We plan to develop, register, and launch our CTLA-4 and PD-1 antibodies. This year, aggregate revenue for antibodies targeting CTLA-4 and PD-1 are expected to be $15 billion. Hence we believe that despite the current players, our antibodies represent a significant commercial opportunity for Agenus. Very recently, we shifted our strategy of first approval to cervical cancer from non-small cell lung cancer. We will be developing the combination of our own two antibodies for cervical cancer. The reasons for our strategy shift include increasingly crowded lung cancer opportunities and Merck’s recent data with Keytruda in combination with chemotherapy in first-line non-small cell lung cancer, which has set the bar higher for any future approvals. PD-1 has also emerged as an important driver of our -- of improved efficacy when used in combination with standard of care, chemo or radiation. We are opportunistically exploring such combinations with our own PD-1 and CTLA-4 antibodies. We continue our commercial launch readiness efforts, we have supplied our clinical programs and have successfully manufactured commercial grade CTLA-4 and PD-1 antibodies. We acquired our California manufacturing facility three years ago and it has proved to provide us with independent, speedy and cost efficient manufacturing capabilities today. Also, lastly before I get into our pipeline, this year we're planning triple combination studies of our proprietary vaccine in combination with both our CLTA-4 and PD-1 antibodies. So far, I have discussed our antibodies which are in the clinic, and touched on our future clinical and product registration plans. I will now shift to our pipeline of a slate of exciting immuno-oncology agents expected to enter the clinic soon. Our novel pipeline is advancing as I mentioned earlier, and we are on track to file six INDs this year and an additional two INDs -- or additional two INDs in the first half of next year. Amongst that, is our next gen CTLA-4, our scientist have discovered a novel mechanism that enhances the function of the today CTLA-4 molecules. These findings are expected to be published shortly. With this feature, our next gen CTLA-4 is designed to deplete T rigs and importantly improve T-cell timing. We and increasing numbers of others expert in the field believe that this beating T rigs is critical to overcoming the limitations of current immuno-oncology treatments and successfully depleting T rigs could expand the market for current treatment significantly. We're also planning IND filings for our bispecific agents this year. These Agenus' bispecific antibodies are design to selectively deplete this time the intratumoral regulatory T-cells as well as condition the tumor micro environment further. We believe these compounds address tumor escape mechanisms in solid tumors as well as mythological tumors like B-cell lymphoma. Lastly, as you all know cell therapy has shown life-saving potential for patients and has created significant value for shareholders. In spite of this current approaches have limitations that are well known including manufacturing and logistical challenges and very high costs of production. We believe AgenTus our cell therapy company has the technologies and capabilities to potentially address these limitations. Last week Dr. Hurwitz presented at PEGS Summit in Boston. Specifically our proprietary platform has generated high quality T-cell receptors, libraries of those receptors designed to target solid tumors. In addition, our allogeneic cell format is designed to address manufacturing and logistical challenges, scalability as well as costs. We also have a very exciting targeting mechanism for both vaccines and cell therapy. It is our proprietary library of phosphorylated targets designed to optimize efficacy with improved safety, potentially with an off the shelf targeting mechanism as well. One of the most compelling advantages for our cell therapy business includes access to de-novo discovery platforms, core capabilities in bio-informatics, structural and computational biology, molecular and cell biology and very importantly a pipeline of validated check point antibodies and bispecific tumor micro environment conditioning agents to rapidly develop first-in-class combinations. These are capabilities all of which we possess in-house, which gives us the ability to innovate and advance programs rapidly. In summary, given our long history in the field of cancer immunotherapy and the key acquisitions we’ve made in the past four years, along with our extraordinarily talented team. We have transformed Agenus into a company with one of the most exciting and extensive pipelines in the field. Also importantly, our capabilities which have generated our exciting pipeline are now advancing next generation opportunities beyond those stated to enter the clinic in the next 12 to 14 months. As I alluded to earlier, also we believe and other experts believe that new mechanisms such as the ability to modify the tumor micro-environment will be the next generation drivers of successful treatment and cures for cancer. We believe we have amongst the best products to accomplish this. In addition our ability to combine these molecules with first generation immuno-oncology antibodies, our new antigen vaccines, our cell therapies and adjuvant provide us unique advantages in the immuno-oncology field, which are very rare. Increasing knowledge of these capabilities and our pipeline have been the key drivers of partnership interest from companies, with which we are in discussions to-date. Thank you very much for your time and interest in our company. We look forward to your questions at the conclusions of our discussion. Christine?
