Thank you, Troy. Let's begin with highlights from our ziftomenib development program. At ASCO 2025, Dr. Eunice Wang of Roswell Park presented data from the KOMET-001 trial evaluating ziftomenib monotherapy in 92 heavily pretreated relapsed/ refractory patients with NPM1-mutant AML. The trial achieved a CR/CRh rate of 23%, surpassing historical controls, with consistent activity across prespecified subgroups, including those with prior transplant, prior venetoclax, those with numerous prior therapies and those with FLT3 or IDH co-mutations. At the time of the data cut, 63% of responders were MRD negative. Ziftomenib's consistent safety and tolerability profile, including effective management of differentiation syndrome, low rate of myelosuppression, lack of clinically significant QTC prolongation and absence of drug-drug interactions underscores its favorable benefit risk profile for patients with relapsed/refractory NPM1-mutated AML. We're progressing through regulatory milestones for our NDA submission, including information requests and pre-approval inspections, in line with time lines for priority review. As Troy noted, our interactions with FDA remain collaborative and constructive. Ziftomenib's favorable safety profile supports its broad use in combinations in both the relapsed/refractory and frontline settings. KOMET-007 and KOMET-008 are evaluating ziftomenib in combination with various standards of care in patients with both newly diagnosed and heavily pretreated disease. At the 2025 EHA Congress, Dr. Harry Erba of Duke University presented Phase Ia/Ib data from the KOMET-007 trial testing ziftomenib at a 600-milligram once-daily dose plus intensive chemotherapy in newly diagnosed NPM1-mutant and KMT2A rearranged AML. Despite available therapies, it's important to remember that up to 70% of AML patients relapse within 3 years, highlighting a substantial unmet need and only 1/3 are alive at the 5-year mark. KOMET-007 data were highly encouraging with rates of complete remission and MRD negativity across the 7+3 cohorts and a safety profile consistent with previous reports. The safety profile observed with ziftomenib in combination with intensive chemotherapy was actually similar to what is expected in patients treated with 7+3 alone. Ziftomenib's continuous daily dosing was maintained through count recovery and consolidation therapy as well as maintenance without delaying neutrophil or platelet recovery or causing any additional myelosuppression. A single case of Grade 3 differentiation syndrome in a patient with KMT2A rearranged AML was successfully managed. Composite complete remission rates were 93% for patients with NPM1-mutant and 89% for KMT2A rearranged AML. Complete remission rates were 84% and 74%, respectively, at the time of this data cut. 96% of NPM1-mutated and 88% of KMT2A rearranged patients remained alive and on study with a median follow-up of 25 and 16 weeks, respectively. MRD negativity was achieved in 68% of NPM1-mutant and 83% of KMT2A rearranged patients with a composite CR at medians of 4.7 and 4.1 weeks, respectively. We anticipate presenting preliminary clinical data from the KOMET-007 trial evaluating ziftomenib at 600-milligram dose with venetoclax and azacitidine in both newly diagnosed and relapsed/refractory AML patients in the second half of this year, potentially at ASH. Last quarter, we broke new ground, aligning with FDA and EMA on the KOMET-017 protocol, which comprises two independent, randomized, double-blind, placebo-controlled Phase III trials. The first is KOMET-017-IC, which is ziftomenib with 7+3 intensive chemotherapy, and the second is KOMET-017-NIC, ziftomenib with venetoclax and azacitidine or a non-intensive chemotherapy. FDA alignment on the use of MRD-negative CR and CR as dual primary endpoints for accelerated approval in both trials could substantially shorten development time lines. The single protocol design streamlines trial startup and is attractive to clinical sites because it accommodates nearly all eligible frontline patients. KOMET-017 is now in study startup and on track for initiation in the second half of this year. Turning our attention to ziftomenib in combination with imatinib for patients with advanced gastrointestinal stromal tumors or GIST. Approximately 4,000 to 6,000 new cases of GIST are diagnosed each year in the United States and advanced GIST patients have limited treatment options. Imatinib, the current frontline standard of care for advanced GIST, targets KIT via tyrosine kinase inhibition, but resistance often develops due to secondary KIT mutations. The KOMET-015 trial will be combining a dose escalation to evaluate the safety, tolerability and preliminary antitumor activity of ziftomenib in combination with imatinib in adults with GIST who are currently on or have previously been treated with imatinib. We're advancing in dose escalation, and we will share clinical data updates as it becomes appropriate. Progress also continues in our next-generation menin inhibitor program for diabetes. We see strategic potential to expand menin inhibition to diabetes and cardiometabolic disease. We've nominated a next-generation development candidate for diabetes, and we'll share development plans and time lines in a future update. Moving now from menin to our FTI development programs. Our FIT-001 trial evaluating our next-generation farnesyl transferase inhibitor, KO-2806, is progressing significantly. Our innovative approach combines FTIs with targeted therapies to overcome resistance and enhance response durability, reshaping the FTI story and expanding the use of these combinations. As Troy mentioned, three clinical abstracts from our FTI program were accepted for presentation at the 2025 ESMO Congress, covering KO-2806 with cabozantinib in renal cell carcinomas, KO-2806 monotherapy in advanced RAS-mutant solid tumors and tipifarnib and alpelisib in patients with PIK3CA mutant head and neck squamous cell carcinoma. We plan to host a virtual event in concordance with the ESMO Congress in October to discuss the emerging clinical data, and we'll share more details ahead of that conference. We're also evaluating KO-2806 and adagrasib in patients with KRAS-G12C mutant solid tumors and are already encouraged by the data being generated in dose escalation. We will look to share data from this combination likely next year. And with that, I'll turn it over to Brian to discuss our commercial readiness activities.
