Thanks, Chip, and good afternoon to everyone on the call. As Chip mentioned, we're excited to be just eight months away from the planned top line results of our Phase 3 lower risk MDS trial. As such, our teams are focused on preparations for high-quality data readout, which requires collaboration and execution across the clinical operations, data management and biostats teams, as well as partnerships with our CRO investigators, and study sites. We remain confident that the readouts will occur in early January 2023. I'd like to remind everyone that the IMerge Phase 3 trial is designed to confirm the Phase 2 results, since the trials use the same patient population, dosing regimen of imetelstat, primary and secondary endpoints and geographies for clinical sites with many of the same investigators. We believe that if the Phase 3 trial confirms similar steps for us, durability of confusion, dependence and safety, imetelstat could need significant needs for all patients with lower risk MDS who has failed or are refractory to ESA treatment. Moreover, imetelstat would address the approximately 75% of lower risk MDS patients who are RS-negative and are underserved by current treatment options. Furthermore, the unique telomerase inhibition mechanism provides disease modifying potential, which we believe differentiates imetelstat from other currently approved, or investigational treatments for low risk MDS. In addition to preparing for top line results, our regulatory team has initiated NDA submission preparations. As Chip mentioned, assuming the results of IMerge Phase 3 support regulatory submissions, we plan to submit an NDA in the U.S. in the first half of 2022 and an MAA in Europe in the second half of 2023. With regards to our Phase 3 refract MF clinical trial, we continue to make progress with site activation and remain confident we will open the remaining selected sites in 2022. We believe this progress will enable completion of enrollment and a potential interim analysis in 2024. As a reminder, IMpactMF is the only Phase 3 trial in MF using overall survival as the primary endpoint. We believe that if the improvements in RS observed in our Phase 2 trial can be confirmed in IMpactMF. Imetelstat could present a potentially transformative treatment option for MS patients who no longer respond to JAK inhibitors, given their dismal prognosis and lack of treatment options. Of note, a recent publication in cancer journal, co-authored by Dr. Mascarenhas and Dr. Verstovsek, both principal investigators in our Phase 3 IMpactMF trial describes the clinical dilemma for treatment of JAK inhibitor failures. This paper reinforces the poor outcomes in many MS patients who are refractory to JAK inhibitors, and highlights the unmet need for survival improvement in this patient population. Moving on to the earlier stage programs in our pipeline, this month, we opened our first clinical site in the improve MS [Ph] study. These Phase 1 study is designed to evaluate the safety and clinical activity of imetelstat in combination with ruxolitinib in patients with frontline MF. In this, in this study, we want to explore the potential for disease modification for imetelstat treatments in the earlier frontline MF disease setting. As a reminder, improved MF with a single arm open label study in patients with frontline MF consisting of two parts. Parts One will enroll up to 20 patients with the objective to identify a safe dose for the combination of imetelstat and ruxolitinib while efficacy data are being collected. In part two, we also plan to enroll approximately 20 patients with the objective to confirm the dose identified in part one, and collect further safety and efficacy data. In both parts, patients who receive ruxolitinib followed by imetelstat, a dosing schedule that showed synergistic and additive effects of the two drugs in preclinical experiments. For our investigator led trials in higher risk MDS and acute myeloid leukemia, or AML, we continue to expect the start in the second half of 2022 our recent non-clinical publication in the Journal of Clinical Medicine, although in pediatric AML further supports the developments from imetelstat in these diseases. Lastly, and in anticipation of likely questions, I want to comment that we have limited clinical trial activity in Ukraine and Russia across all our on-going trials. At the moment, we believe that the conflict will have no significant impact on our trials or on our timelines, including top line results for IMerge Phase 3, and enrollment and interim analysis for IMpactMF. I would now like to turn the call over to our Chief Financial Officer Olivia Bloom for financial update. Olivia?
