Thank you, Adam. This morning, we reported results for the first quarter of 2026, and I am pleased to say we've had a strong start to the year. Both active patients and net revenues grew at double-digit rates year-over-year. Our launch in pancreatic cancer is off to a promising start, and we are making progress on our journey to profitability. With a number of additional catalysts expected this year, we look forward to building on this strong first quarter. On today's call, we will begin with a review of our pancreatic cancer program. Frank will then provide an update on our GBM and lung cancer programs. Christoph will conclude with a review of our first quarter financial performance before we open the line for questions. The leading news in the quarter was the FDA approval and subsequent U.S. launch of Optune Pax for patients with locally advanced pancreatic cancer. Physician feedback has been positive since the PANOVA-3 data were presented and published at ASCO last year. There is broad recognition of the importance of the outcomes observed, including extensions in overall survival and time to pain progression. We believe Optune Pax can play a significant role in the treatment of pancreatic cancer, and we are pleased to be bringing Optune Pax to pancreatic cancer patients. The early days of our Optune Pax commercial launch have been encouraging. We received FDA approval on February 11. In the 7 weeks, between the approval and quarter end, we certified 868 health care providers, 27 of whom are prescribers in academic centers. An exciting development as historically, we've seen slower adoption of TTFields therapy in academic centers. Through March 31, we've received 169 prescriptions and completed 90 patient starts. We ended the quarter with 83 patients on therapy and a backlog of starts in the funnel. We are also pleased to report our first major payer coverage policy for Optune Pax with Elevance Health, covering over 30 million lives. It will take a few quarters to fully understand the Optune Pax adoption curve and reimbursement dynamics. But again, the early signals are very encouraging. During the quarter, we also announced top line data from the Phase II PANOVA-4 trial, evaluating TTFields therapy together with atezolizumab and Gem-Abraxane in metastatic pancreatic cancer. PANOVA-4 met its primary endpoint with a disease control rate of 74% compared to 48% in the historical control. Median duration of therapy was 25.6 weeks, a strong indication that TTFields therapy is feasible for use in the metastatic population. As the pancreatic cancer treatment landscape evolves, we will evolve with it. After years of limited clinical success in pancreatic cancer, the medical community has seen positive outcomes in the PANOVA-3 and PANOVA-4 trials, and positive data from a trial testing the pan-RAS inhibitor, daraxonrasib in second-line metastatic pancreatic cancer. RAS inhibitors are likely to be an important backbone therapy in pancreatic cancer in the future, and we are working to understand the benefits of their concomitant use with Tumor Treating Fields. Earlier this month, at the American Association of Cancer Research, or AACR Annual Congress, 2 posters were presented, which evaluated in vitro and in vivo use of TTFields with daraxonrasib in pancreatic cancer models. The data presented show that KRAS inhibition, which blocks upstream oncogenic signaling and the down-regulation of the c-Myc protein caused by TTFields produced greater antitumor activity when used together compared to either therapy used alone. These data are promising, warrant clinical investigation and will be important inputs as we consider the next steps in our pancreatic cancer program. Finally, a quick update on our product development initiatives. Over the last year, we've launched a number of product enhancements aimed at making TTFields therapy easier for patients and prescribers. This includes an HCP portal, which simplifies the prescription process, lighter, more flexible, more comfortable HFE arrays for Optune Gio, a mobile app to help patients and caregivers navigate their TTFields experience. We are starting to see the fruits of these enhancements in our 90-day persistent rate, which hovered below 70% as recently as 2024. In 2025, we have seen quarterly persistence rates tick up to 73%. Our next major product improvement will be a new array for the torso. We are now finalizing the design, which will be compatible with Optune Pax and Optune Lua. The new arrays are designed to make major improvements in comfort and usability. We also expect these arrays to be more cost effective to manufacture. We have completed usability testing in healthy volunteers and are evaluating performance in non-small cell lung cancer patients. Our next aim is to have the new arrays available for use in future pancreatic and lung cancer clinical trials by year-end. I'll now pass the call over to Frank for an update on our GBM and lung cancer programs.
