Thank you,ÃÂ Yvonne, and a warm welcome to everyone joining our call today. On today's call, I will highlight some of our key achievements in 2024 and outline our strategic priorities for 2025. Starting with our potential first-in-class anti-PVRIG COM701. In 2024, we presented data showing the treatment with a triple blockade of PVRIG, TIGIT and PD-1 with COM701, COM902 and pembrolizumab in platinum-resistant ovarian cancer patients who typically do not respond to immunotherapy, resulted in encouraging durable responses and was well tolerated.ÃÂ As of mid-February 2025, a few patients remained on study treatment. The data from this study is important because it is consistent with data we previously presented and further demonstrates COM701 is active, results in durable responses and has a good tolerability profile. Based on the totality of the data we've presented to date, including monotherapy and combination data and with the support from ovarian cancer experts, we announced at the end of 2024 that we would advance development of COM701 as a maintenance treatment option for patients with platinum-sensitive ovarian cancer.ÃÂ We believe that advancing COM701 in this maintenance setting of platinum-sensitive ovarian cancer has a strong clinical and biological rationale and represents a less competitive landscape.ÃÂ As part of our 2025 strategic priorities, we are on track to initiate in the second quarter of 2025 an adaptive platform trial, starting with a randomized, double-blinded sub-trial. The first sub-trial will evaluate single-agent COM701 as a maintenance therapy versus placebo in total of 60 patients with platinum-sensitive ovarian cancer who are not candidates for bevacizumab or PARP inhibitors. The primary endpoint will be median progression-free survival where the placebo benchmark is expected to be approximately 6 months. We believe that showing a 3-month improvement over the median progression-free survival of the placebo would be clinically meaningful. We expect to share interim analysis from this sub-trial in the second half of 2026. Positive data may allow us to boost engage in discussions with the regulatory authorities on the path for COM701's registration as a single agent and to extend the opportunity for COM701 to serve as the backbone for future drug combinations.ÃÂ Moving next to the TIGIT landscape. In 2024, there have been several setbacks for the TIGIT antibody class, resulting in study or program discontinuations, which led to skepticism about the benefit that TIGIT blocker combinations could bring. These study discontinuations occurred with Fc active TIGIT antibodies. Setting aside the importance of selecting the appropriate tumor types and patient populations that in some cases, might not have been an ideal fit for TIGIT blockers assessment. We consistently have advocated that Fc inactive antibodies may serve as the better antibody format for targeting TIGIT. In line with this, current clinical trials suggest that Fc inactive anti-TIGIT may have a safety advantage in certain patient populations. Which could ultimately support a potential efficacy advantage due to the patient's durability on study treatment. We therefore, believe that the current Phase III trials conducted with Fc inactive TIGIT antibodies are important to confirm or refute the benefit that TIGIT blocker combinations could bring.ÃÂ If success is achieved by one of these upcoming Phase III trials, it could validate TIGIT antibodies as a drug class, and open new opportunities for Compugen based on our TIGIT antibody. We're one of the few companies with a clinical-stage Fc inactive TIGIT antibody, COM902. We differentiate ourselves not only by the unique properties of COM902 but also by our clinical strategy. We continue to believe that blocking TIGIT in combination with PD-1 blockers may be effective in certain PD-L1 high tumors.ÃÂ But we also believe that TIGIT PD-1 blockade may need to be combined with a PVRIG inhibitor to expand their use to less inflamed PD-L1 low tumors. In addition, our partner, AstraZeneca, has most recently initiated their seventh Phase III clinical trial with rilvegostomig, their PD-1 TIGIT bispecific, the TIGIT component of which is derived from our COM902. Since we last reported in November 2024, AstraZeneca has initiated two Phase III trials evaluating rilvegostomig combinations versus standard of care with one trial in first-line squamous non-small cell lung cancer expressing PD-L1 and the other trial as first-line treatment in HER2-positive gastric cancer. AstraZeneca's broad development strategy for rilvegostomig to replace existing PD-1 or PD-L1 inhibitors represents a significant potential revenue source for Compugen as we're eligible for both future milestone payments and mid-single-digit tiered royalties on future sales. In 2024, AstraZeneca presented promising rilvegostomig data at the World Conference of Lung Cancer and ESMO, showing promising efficacy and a manageable safety profile in both lung and gastrointestinal cancer. In 2025, AstraZeneca plans to share early data on the combination of rilvegostomig with their ADCs. Moving next to GS-0321, previously named COM543. As a reminder, GS-0321, a potential first-in-class anti-IL-18 binding protein antibody, licensed to Gilead represents a novel way to harness IL-18 pathway biology for the treatment of cancer by using an antibody against IL-18 binding protein and therefore, potentially avoiding the challenges presented by administration of therapeutic cytokines. The license by Gilead of GS-0321 further validates our computational discovery, research and drug development capabilities. It is also a testament to the differentiation of our antibody program targeting the IL-18 binding protein. In 2024, we also made great progress on GS-0321. In the third quarter of 2024, we received a $30 million milestone payment from Gilead for achieving the FDA IND clearance. In the fourth quarter of 2024, we initiated the Phase I trial for GS-0321 and the first patient was dosed in early January 2025. As part of our strategic priorities in 2025, we're focused on the efficient execution of the GS-0321 Phase I trial. Finally, beyond our clinical stage programs, our talent and teams are working on multiple innovative undisclosed research programs. These efforts leverage computational predictions to identify novel ways to activate antitumor immunity. This work is powered by Unigen, our computational prediction discovery platform already validated by our multiple clinical stage potential first and best-in-class antibodies as well as our partnerships with AstraZeneca and Gilead. It is a strategic priority for us to advance our programs to continue to feed our own pipeline. With a diverse pipeline and strong focus on execution in 2025, we believe Compugen is well positioned for growth. Cash runway, assuming no further cash inflows is expected to last into 2027, and we anticipate using this runway to advance the projected COM701 single-agent sub-trial interim analysis and to support the progression of GS-0321 in the clinic, together with continued investment in our early-stage research pipeline. Of course, none of this will be possible without our extraordinary team here at Compugen who continuously perform at the highest levels of excellence. I'm excited for 2025 to be another year of advancing our efforts to make a meaningful impact on cancer patients' lives. With that, I will hand over to David for the financial update before we open the floor for Q&A.
