Thank you, Aaron. Good afternoon, everyone, and thank you for joining us. I'm very proud of our team at Personalis as we continue to fight cancer with our noble technologies. For those of you joining one of our calls for the first time, welcome. Personalis is one of the leaders in the fast-growing MRD testing market. MRD stands for minimal residual disease. With our first-of-its-kind ultrasensitive MRD test, we're able to spot cancer when it's only one fragment of tumor DNA circulating in 1 million DNA fragments in the blood. Our technologies are used by many of the world's top biopharma companies to improve clinical trial results by new ways to personalize treatment and power a new generation of more effective therapies. Last quarter, we laid out a strategy to drive Personalis to $100 million in revenue in 2025. This aspirational milestone with 3 underlying growth engine is our large star as we are accelerating Personalis into a higher growth mode. In the first quarter, we achieved revenue of $19.5 million, exceeding the upper end of our guidance of $18 million to $19 million. Our biopharma business grew 55% compared to the first quarter of 2023, driven by strong demand for our core ImmunoID platform to support the individualized neoantigen therapy market as well as increasing demand for our MRD product mix personal. With this increased demand, we have the confidence to increase our full year revenue guidance to $76 million to $78 million from $73 million to $75 million. I'll now review progress this quarter on the 3 growth engines driving us towards our $100 million in 2025 goal and our progress on each. The first growth engine is the most important as we focus on turning Personalis into a clinical diagnostic powerhouse. In order to do that, we're executing on our win and MRD strategy. The MRD market involves using liquid biopsy to find evidence of minimal residual disease or cancer recurrence and subsequently monitoring therapy effectiveness. It's estimated that this market will mature into a $20 billion opportunity over the coming years, and we are establishing Personalis as a leader in the space. Our win and MRD strategy has 4 pillars. First, to focus and launch our tests in cancer types where an ultrasensitive liquid biopsy test and unlock significant value for patients, payers and partners; second, to drive reimbursement by developing robust clinical evidence and partnering with the top global collaborators; third, leverage our deep relationships to accelerate adoption by biopharma partners empower our revenue growth by the use of next personal and clinical trials. And lastly, to commercialize next personal with a partner-centric model. To delve into the first pillar, we previously explained how we're developing evidence to support NeXT Personal's clinical usage and reimbursement in early-stage lung cancer, breast cancer and immunotherapy monitoring. We believe our ultrasensitive technology allows us to see cancer earlier, which may provide the information to deescalate patients from unnecessary to necessary therapies and procedures potentially sparing patients from toxicity and saving health care dollars. This is importantly, we believe we can identify and get recurrent patients to treatment earlier with potentially better outcomes. Our focus on these indications is intentional, and our data has demonstrated that NeXT Personal can win in these markets. To elaborate a bit on our approach, early-stage lung cancer and breast cancer shed very little DNA into the blood, which are difficult to detect without an ultrasensitive approach. Early detection is critical in these indications. For patients on I/O therapy, we believe the potential decision to switch treatment requires the insights for monitoring that are provided by ultrasensitive tests. Now, you might recall that last October, we launched our MRD test NeXT Personal. And today, we are enrolling physicians in an early access program, or EAP. We are the first ultrasensitive MRD test to commercially enter the market. And with that launch, we now have 2 laboratory developed tests for LDTs on the market, the other being our Medicare reimbursed test NeXT Dx, which is used by physicians to put a patient on targeted therapy. The adoption of these tests has been ramping and is exceeding our initial target. We delivered 338 clinical tests in the first quarter, a solid uptick from the 126 results delivered in the fourth quarter of last year. We're pleased with this traction as the number of physicians that were ordering in Q1 remain fixed to 10 through the quarter. There are 2 key metrics that I want to talk about and dive into. First, all 10 of our early access positions are ordering an uptick has been strong across the entire cohort. The second metric involves the actionability of our next personal MRD test for the clinic. If you remember, we report circulating tumor DNA in the blood down to 1 part per million, which means if there is just one fragment of tumor DNA circulated and 1 million DNA fragments in the blood, we expect to see and quantify it. This is a lead forward for the field. The extra sensitivity we report on with our NeXT Personal assay, which are values between 10 and 100 parts per million, a mask a region that has previously been hard to see consistently. We call that region the ultrasensitive MRD range. Inter NeXT Personal clinicians could not routinely detect cancer recurrence at that level and today, they can. About 40% of the ctDNA positive samples thus far in our clinical testing have been in this ultrasensitive range. That's a significant jump in the performance of MRD testing and means that physicians can see cancer recurrence earlier, have more discrimination in monitoring therapy and have more confidence that ctDNA patients that are negative are likely cancer free. Indeed, we've had many antidotes relayed from our 10 early access doctors that the ultrasensitive range is allowing them to see cancer earlier with their patients and intervening to get them the management they need. We believe it is the ultrasensitive range that allows the doctor to see cancer sooner, and seeing it sooner is the cornerstone of our win in MRD strategy. Now, moving to the second pillar. We're focused on building and publishing clinical evidence to gain reimbursement and are working with many of the top thought leaders in the world. In previous calls, we've talked about the importance of our work with Royal Marsden in breast cancer and BHIO and immunotherapy monitoring. Both of these collaborators have provided access to studies that are broad and comprehensive. In the case of Royal Marsden, one of the leading global institutions in breast cancer, we're focusing on patients with early-stage disease for several subtypes, including ER positive, HER2 positive and triple-negative breast cancer. For BHIO, the work is pan-cancer across many cancer types and stages. These studies are anchor studies and that they will be the backbone of our efforts to gain Medicare reimbursement. Royal Marsden for early-stage breast cancer and BHIO for immunotherapy monitoring. We're excited that at the upcoming ASCO conference, the work with both of these collaborators will be featured as oral podium presentations. We also have 3 other studies featured at ASCO, one with Dana Pharma on HER2-positive patients and other with Duke immunotherapy monitoring for gastric patients and lastly, 1 in colorectal cancer patients. Having this brands of data should underscore our commitment of Personalis to developing rich data to support the use of NeXT Personal in the clinic and to gain reimbursement quickly. At the AACR conference in April, some compelling data was presented. Our collaborators from the U.K. gave an oral podium presentation on late-stage melanoma patients where they use NeXT Personal to monitor and detect immunotherapy response, highlighting the importance of detection of ctDNA in the ultrasensitive range. In addition, our work in collaboration with Astra
