Thank you, Robert Ragusa, and hi, everybody. We were really pleased last month to share very positive performance and safety results from the pre-specified analysis of the first 25,000 participants in our registrational PATHFINDER II study. This study started in 2021, and PATHFINDER II is a large prospective trial in a very broad and diverse enrolled group representative of Gallery's screening-eligible intended use population. Releasing the first results of this study at ESMO was so exciting and a big milestone for our company, and all of our partners and investigators. It was a meaningful contribution to the evidence base for the effectiveness of multi-cancer early detection. As you will recall, we found that adding Gallery to recommended screening for breast, cervical, colorectal, and lung cancer yielded a more than sevenfold increase in the overall cancer detection rate. Approximately three-quarters of the cancers detected by Gallery have no recommended screening options. More than half of the new cancers detected by Gallery were in stage one or two, and more than two-thirds detected at stages one, two, or three. One of the most important clinical metrics, the positive predictive value or PPV, which is the likelihood of receiving a cancer diagnosis following a positive test result, Gallery's PPV was 61.6%. Specificity was 99.6%, translating to a false positive rate of 0.4%, a critical safety metric. Gallery's ability to accurately identify where in the body cancer is located also helped guide an efficient and effective diagnostic evaluation. Importantly, there were no serious study-related adverse events reported thus far. Diagnostic resolution, an important economic and patient-centered outcome measure, took a median of 46 days. Only 0.6% of all participants had an invasive procedure, and again, no serious study-related adverse events were reported. Invasive procedures were two times more common in participants ultimately diagnosed with cancer than in those who were ultimately not diagnosed with cancer. PATHFINDER II and NHS Gallery make up our registrational clinical program for Gallery. Our PMA submission will include these data from the first 25,000 enrolled in PATHFINDER II, to complete twelve months of follow-up, plus findings from the prevalent round of screening from the NHS Gallery randomized clinical trial, as well as the results of a bridging study between the version of Gallery used in the two registrational trials to the updated version that we plan to submit to the FDA for premarket approval. As a reminder, we announced positive top-line results from the prevalent round of screening in the NHS Gallery trial in May. Namely, the data from the prevalent screening round showed a substantially higher positive predictive value than that was observed in the first PATHFINDER study. Now to review important new findings from our SIMPLIFY study, I will hand it off to Harpal S. Kumar. Thanks, Joshua J. Ofman, and good afternoon, everyone.
