Thank you, Elana. Good morning, and good afternoon everyone. I would like to welcome you to our fourth quarter and full-year 2018 corporate and financial update. As Elana mentioned, with me today are Dr. Henry Adewoye, our Chief Medical Officer, who will update you on our COM701 Phase I study; and Ari Krashin, our CFO and COO, who will provide a financial update. As we announced in today's press release, after reaching a number of important milestones in our corporate development during 2018 and forward integrating clinical capabilities into our organization, we undertook a comprehensive review of the company's operations and cost structure, and are now implementing a process of corporate restructuring to streamline our operations and focus on our core value drivers. The corporate restructuring consists of three key elements, a reduction of approximately 35% of our workforce, which is about 35 employees, the majority of which is in R&D, consolidating our R&D activities in one location by eliminating the overlap in R&D and G&A activities which exists today between the two R&D centers in Israel and in South San Francisco, and phasing out our R&D laboratory activities in the United States, and outsourcing certain preclinical activities that are currently conducted in-house. Our clinical development and business development will continue to operate in the U.S. These changes and resulting cost reductions are being taken to accomplish two main objectives. First, to allow us to have the necessary resources to execute our own growing Phase I studies for COM701, including the initiation of extension cohorts for combination studies with Opdivo; this is our highest priority. Second, it will allow us to maintain and continue investing in our long-term core value drivers, our proprietary computational target discovery platform, and our early stage immuno-oncology pipeline. The cost reductions are expected to extend…

Thank you, Anat, and good afternoon, good morning everyone. As Anat mentioned, we are focused on the COM701 clinical program and our ongoing Phase 1 clinical study evaluating COM701 as monotherapy and in combination with Opdivo in patients with advanced solid tumors. As you may recall, the combination arm of this study is in collaboration with our partner Bristol-Myers Squibb. The study is designed to address the scientific and clinical rational of the COMP701 program which evaluates inhibition of component of the DNAM axis, PVRIG and its ligand PVRL2 leading to activation of T-cells in the tumor microenvironment in patients with advanced solid tumors. In addition, the suggested intersection of PVRIG and PD1 pathways provides a strong combination rationale of COM701 with PD1 inhibitors. This is complimented by the biomarker strategy which is implemented in the protocol and is based on our understanding of the biological pathway of PVRIG and as supported per clinical data. The primary objective of the study is safety and tolerability evaluated by dose-limiting toxicities and the determination of a maximum tolerated dose including pharmacokinetics. A secondary objective is the evaluation of preliminary anti-tumor activity of COM701 in combination with Opdivo inpatients with selected tumor types. At this time, the study is enrolling patients into ARM A evaluating COM701 therapy do escalation in our comments. That is patients who have exhausted all available standard therapies. At the completion of the immunotherapy dose escalation study, we expect to have a recommended Phase 2 dose of COM701. I am pleased to inform you that the study is progressing as planned, site recruitment and patients enrollment are on the track, the investigators on this study are excited and very engaged in the study as the COM701 as a novel and first-in-class investigational monoclonal antibody with the unique mechanism of…

Thank you, Henry. Our financial results for the fourth quarter in full-year 2018 released today are in line with our expectations. In general, they continue to reflect the increase in clinical development expenses attributed to the progress made with COM701 as well as the preclinical expenses associated with manufacturing and IND enabling studies for COM902. Our total cash expenditures during 2018 totaled approximately $36 million. The announced restructuring is expected to provide us with anticipated savings of up to $10 million on an annual basis. As a result, we expect that the cash expenditures for 2018 including one-time restructuring related costs will be significantly lower and will be in the range of $27 million to $29 million with the full effect of the savings reflected in 2020. We ended 2018 with approximately $45.7 million in cash and cash related accounts compared with $30.4 million at the beginning of 2018. The company has no debt. The net increase in our cash balances is attributed to the revenue during 2018 which were comprised of $10 million from the license agreement with AstraZeneca to $7.8 million from Bayer resulting from the clinical milestone achieved as well as a $12 million investment made by Bristol-Myers Squibb and the $20 million net from the registered direct offering offset by our 2018 cash expenditures. The restructuring process required us to make some difficult decisions. However, we believe they were necessary for us in order to become a more financially stable company. It removed some of the cash overhang and will extend our cash run rate through mid 2020 to allow the continued funding of the planned expansion of the ongoing Phase 1 study for COM701 and the focus on the long-term value drivers of our organization. Having said that, I would like to remind you that…

Thank you. Ladies and gentlemen, at this time we will begin the question-and-answer session. [Operator Instructions] The first question is from Mark Breidenbach of Oppenheimer. Please go ahead.

Hey, good afternoon guys. Thank you for taking my questions. I think I heard Henry slip in some very important guidance there. I just wanted to reconfirm I heard him correctly, that you expect to begin dosing patients in the Opdivo combination expansion trial beginning in second quarter, and you expect to complete enrollment of both the dose escalation monotherapy trial and in the combination expansion cohorts in the second-half of this year. Was that correct, did I hear that right?

Hi, Mark. Just some little corrections, so the second quarter of 2019 we expect to initiate the combo dose escalation, not the expansion, so the escalation. And for the second-half of 2019, we expect to complete enrollment for the monotherapy dose escalation, that's COM701, and also complete enrollment of the dual combination dose escalation cohorts.

Okay, so expansion cohorts will still maybe be ongoing or will not wrap up by the end of this year. I have another question, where there any specific triggers or events that needed to be satisfied before the COM701 plus Opdivo dose escalation cohort could begin enrolling in the second quarter?

Sure. So, without disclosing what's current in terms of clinical data, it's the numbers based on what we have assessed as dose-limiting toxicities that we will disclose during the ASCO-SITC abstract and poster presentation. So we're confident in the data that we're seeing, and that's what's triggering the dose escalation. So, things are going on track, in short.

Okay. And with regard to COM902, which you mentioned was the development has sort of been aligned with your plans for COM701. Would you anticipate you'll be in a position to make a go or no-go decision for continued development later this year or is it a question of sort of a second-half '19 versus a 2020 event before we might see COM902 enter the clinic?

I believe that was in Anat's…

Yes, Henry, I'll take it, thanks. So, yes, you heard correctly that we are going to align our plans for COM902 with our plans under the Bristol collaboration, it is very important for us. Obviously, the plan with Bristol is to test various combinations including their anti-TIGIT with COM701 and Opdivo, and not necessarily we will wait to see ultimate data, but that will be dependant, as I just said in my prepared remarks, it will be dependant on the plans moving forward, and funding for the trial on the behalf of Compugen. So, that's basically the two things. Having said that, we're moving forward in filing the IND during '19, and we will obviously advice the shareholders of this step taken.

Okay, thank you so much for taking the questions, and congrats on making progress with the COM701 trial.

Thank you.

The next question is from Peter Welford of Jefferies. Please go ahead.

Hi, thanks. Just sticking with 701 Phase Ia trial, and I'm just trying to understand, I think originally you were starting at very, very low doses with that in single subjects and titrating very slowly as per FDA requirements. Given we're going to potentially start now combo dose escalation in 2Q, and also anticipates then finish enrollment. Should we take that as being that you've reached the sort of recommend Phase II dose, if you would like, for instance, relatively early in the dose titration or is it just that you've passed quite quickly through the various dose stages? I guess just give previous commentary, it seems quite early, and I wonder if you could comment at all on that. And then also on arm B, just wondering then when we start the dose escalation combo, do you then again, in arm B, start at sub therapeutic levels or will that trial start at a level that is therapeutically relevant? And if I could just ask one on the financial, Ari, can you just give us some sort of ideas as to the cash costs for the restructuring we should we see in '18? So I guess when we think about $27 million to $29 million, how much of that $27 million to $29 million is, if you like, one-off cash charges, and so then we can consider sort of the underlying run rate. Thank you.

Sure. Thank you, Peter. This is Henry. So, with regards to your first question, the short answer is we're progressing pretty fast through the dose escalation cohorts. We haven't reached the MTD yet, and hence the reason why we've escalated rapidly through these single-dose cohorts, and how at the 3+3 study design. With regards to the second question, in COM701 in combination with Opdivo, we will start at a dose which we project will be tolerable, and much lower dose than what we are currently using, just because of safety reasons. Not because we have seen any toxicities, but because that's what's written in, as I said, in the protocol.

Okay, thank you, Henry. And Peter, I'll address your question about the restructuring costs. So, as we stated the budget or the expected expenditures for 2019 going to be in the range of $27 million to $29 million. I can share with you that the restructuring cost is probably going to be lower than $2 million, it's not going to be higher than that, it's still in the range between $1 million to $2 million, depends on multiple elements. But I can also share with you that even going into 2020, the capital expenditure, the total is going to be even lower than that for two main reasons. First of all, we just initiated the restructuring, so Q1 of 2018 did not benefit from the saving, and also in 2020 we will not have the restructuring costs. So if I have to guess at the moment, we clearly didn't finalize the budget for next year, but I would assume that next year it's probably going to be even lower by $2 million to $3 million, even $4 million compared to the range that I just gave for 2018.

That's great. Thank you.

This concludes our Q&A session. I would now like to turn the call back to Compugen's President and CEO, Dr. Cohen-Dayag. Would you like to make your concluding statement?

Thank you, Operator. 2018 was a remarkable year for Compugen, with strong execution. I am very proud of the progress we have made this year in achieving corporate goals. We brought COM701 to the clinical, BAY 1905254 being developed by Bayer also entered Phase I studies, and we executed two new pharma deals which substantial our discovery and development capabilities. In recent weeks, we undertook a comprehensive overview of our operations and reached a difficult decision, to implement a corporate restructure. Layoffs are never an easy decision, but we believe this is the correct next step for Compugen. The resulting company will be smaller, with a cost-effective structure that is more appropriate to a company in our early stages of clinical development. We will be more efficient and focused on activities that will bring the greatest value to our shareholders and patients. Thank you for joining us today. I look forward to continue updating you on our activities in 2019.

Thank you. This concludes the Compugen Ltd. fourth quarter 2018 financial results conference call. Thank you for your participation. You may go ahead and…
