Thank you, Diantha. Good morning, everyone, and welcome to Curis’ second quarter business update call. Let’s start with our TakeAim Lymphoma study, which is evaluating emavusertib in combination with ibrutinib in relapsed/refractory PCNSL patients that have failed after treatment with a BTK inhibitor. These patients have generally seen methotrexate chemo and radiation in the front-line setting, followed by ibrutinib in the second line. As patients progress on ibrutinib, they’re eligible to enroll into our study where we add emavusertib to their ibrutinib regimen. The scientific thesis for this combination is that blocking both of the pathways driving NHL, the TLR pathway with emavusertib and the BCR pathway with ibrutinib, can enable patients to achieve an objective response even after they have progressed on ibrutinib in monotherapy. We presented data for the first five patients in this study at the ASH conference last December, where we reported an objective response rate over 50%. These data were early but very encouraging, especially given the high unmet need in this population. We’ve continued to enroll patients in this study, and as we noted in our press release this morning, have recently initiated discussions with regulatory authorities to gain alignment on the registrational path for emavusertib in combination with ibrutinib in primary CNSL. It goes without saying that defining the registrational path is a critical next step in emavusertib’s development, and I’m pleased with our most recent engagement with FDA. I look forward to communicating the outcome of these discussions at the appropriate time. Discussions are also progressing in Europe, where we’re pleased to report that emavusertib has been granted orphan drug designation for primary CNS lymphoma by the European Commission. This designation provides several benefits, including 10 years of market exclusivity, reduced fees for protocol and scientific assistance, as well as marketing authorization applications, and a central application process for marketing authorization with the European Medicines Agency. While these regulatory discussions are ongoing, we continue to make excellent progress on the operational front as well, and expect to reach our target number of 30 clinical sites in the U.S. and Europe, and have initial data for 15 to 20 patients by year end. Now let’s move to our TakeAim Leukemia study, which is evaluating emavusertib in monotherapy in patients with relapsed/refractory AML. At ASCO and EHA earlier this year, we provided updated data for two patient populations in this study, patients with a splicing factor mutation and patients with a FLT3 mutation. In the splicing factor mutation, four of 18 evaluable patients achieved an objective response, including one complete remission or CR, two CRs with partial hematologic recovery, or CRh, and one morphologic leukemia-free state or MLFS. In the FLT3 population, six of 11 evaluable patients achieved an objective response, including three CRs, one CRh, and two MLFSs. Also of note, three of the patients were naïve to treatment with a FLT3 inhibitor. All three of these patients achieved objective responses, and three of the remaining eight patients, those who had failed prior treatment with a FLT3 inhibitor, were able to achieve an objective response with emavusertib. We believe these data support emavusertib’s novel mechanism and its potential as a treatment for patients with relapsed/refractory AML. In the frontline setting, you may remember that preclinical data demonstrate a synergistic effect when emavusertib is combined with azacitidine and venetoclax, the standard-of-care in frontline AML. We recently initiated a study of this triple combination, that is emavusertib in combination with azacitidine and venetoclax in frontline AML. We expect to have initial safety data from this study later this year. Overall, I’m very pleased with the progress in both our TakeAim Leukemia and TakeAim Lymphoma studies, and I look forward to providing additional updates as the year progresses. With that, I’ll turn the call over to Diantha for the financial update.
