Thank you. If we could move to Slide 14. This slide summarizes our plans for label expansion of Ryoncil into adults. A pivotal study of Ryoncil as part of second-line treatment regimen in adults with severe steroid-refractory graft versus host disease is underway with our partners at the NIH-funded Bone Marrow Transplant Clinical Trials Network. The basis for this trial is that 50% of adults who have severe GVHD fail existing second-line treatment, including predominantly ruxolitinib. These patients who fail have a 25% abysmal survival at 100 days. We have previously used Ryoncil under expanded access in patients aged 12 and older, in many adults as well, 18 and older who have failed ruxolitinib or other second-line agents and use of our product in this patient population was associated with 76% survival at day 100, a remarkable result. As a result of these results, the final protocol design for the registrational study in adults has been locked down and has been worked through with the FDA recently in a meeting with the FDA agency. We expect that following Central Institutional Review Board approval coming up in March, site initiation and patient enrollment will commence. Next slide, please. Further extension strategy for Ryoncil is focused on various opportunities in pediatric and adult inflammatory diseases. The team is currently evaluating multiple indications to unlock value, including in the inflammatory bowel, neurodegenerative and respiratory conditions. Our portfolio will be prioritized to maximize shareholder return by utilizing either internal investment strategies versus external partnership initiatives. Next slide, Slide 16. Now I'll be updating you on our second-generation platform, rexlemestrocel-L currently being developed for discogenic chronic low back pain and chronic ischemic heart failure. Slide 17, our Phase III chronic low back pain program, a first 404-patient randomized controlled Phase III trial has already completed, and that included about 40% of patients who are opioid dependent. We met with the FDA recently and received positive feedback on potential filing of a BLA based on achieving a clinically meaningful reduction in pain intensity at 12 months between the treatment arm and placebo arm. The robust result in opioid reduction from at least one adequate and well-controlled trial could be included according to our meeting with the agency as part of product labeling, which is a very, very, very important outcome. We, in fact, do already have an RMAT, Regenerative Medicine Advanced Therapy designation for rexlemestrocel-L as a potential opioid-sparing therapy in chronic lower back pain. Next slide. The confirmatory Phase III trial is recruiting currently 300 patients across 40 sites in the U.S. with a primary endpoint, 12-month reduction in pain. As I've mentioned on multiple occasions, FDA has confirmed that, that is an approvable endpoint. The enrollment of these 300 patients is expected to be completed in March or April. Data readout and BLA filing are expected in calendar year 2027. We have, at the same time, undergoing commercial manufacturing in order to leverage our existing capacity and cost efficiencies. I will reinforce that there are many patients who are suffering from this terrible disease. Over 7 million patients across each of the U.S. and EU5 are due to generative this disease, patients who are otherwise have run out of options other than surgery. This is a large unmet need for a potential blockbuster opportunity. Next slide, Slide 19. Now I'd like to update you on Revascor, our product based on our rexlemestrocel-L platform that is being developed for chronic heart failure with reduced ejection fraction and persistent inflammation in either patients with Class II/III heart failure or very end-stage heart failure patients who are being kept alive with a ventricular assist device in the left ventricle. We can go to Slide 20. LVAD implantation improves overall survival in these end-stage patients, and that's well established. However, the underlying causes of heart failure in these patients, notably inflammation, persists. And whilst the left ventricle improving the left side -- the LVAD is improving on the left side of the heart, the right ventricular pump function remains vulnerable and continues to deteriorate. Therefore, progressive right heart failure continues to occur in up to 30% of patients and is the primary cause of multi-organ failure and death in this group of patients, mortality occurring within the first 12 months. In addition, life-threatening major mucosal bleeding due to progressive right heart failure and portal hypertension occur in about 30% of patients and is the major morbidity in this group, the main cause of recurrent hospitalization. Next slide. Now we performed 2 randomized controlled studies in this patient population. The more recent study was called LVAD Study II, and that randomized 159 patients in a 2:1 randomization to provide primary evidence of Revascor's efficacy in reducing major bleeding events. A second study, LVAD Study I, an earlier study, is a supportive study for LVAD II, randomized 30 patients in a 2:1 fashion and provided supportive evidence also of Revascor's efficacy in reducing major bleeding events. Intramyocardial injections in both of these studies of either Revascor or control were performed at the time of LVAD implantation. Importantly, both trials, both randomized controlled trials showed the Revascor reduced cumulative incidence of major bleeding events, life-threatening GI bleeding, the trial's primary efficacy and safety endpoint and related hospitalizations through 6 months, both were significant. We go to the next slide, Slide 22. This provides you with some new data that we have not previously presented. This slide demonstrates the total number of major bleeding events resulting in hospitalizations over 6 months on the left-hand side and over 12 months compared to controls in the entire study LVAD II. As you can see both on the left-hand side and the panel B on the right-hand side, Revascor reduced major bleeding events and hospitalizations by about fivefold, a very significant reduction throughout a 12-month period compared to MPC treatment compared to control treatment. Next slide, please. Now moreover, particularly in the ischemic group of patients, what you can see is that on the left-hand side, in controls, in red, the ischemic controls had approximately a three to fourfold increase in hospitalizations due to right heart failure. The non-ischemics had a very low incidence and risk of heart failure hospitalization. In contrast, on the right-hand side, by 12 months, you can see that the MPC treatment reduced the right heart failure hospitalization events in ischemic patients back to background levels, the same levels as I see in non-ischemic controls. And again, those reductions of hospitalization from right heart failure were significant. Next slide, please. This slide focuses on the risk of death from right heart failure in controls on the left, and in Revascor-treated patients on the right. As you can see in Panel A on the left, amongst patient controls who have at least one hospitalization from right heart failure, the presence of -- sorry, amongst controls, the presence of right heart failure hospitalization, at least 1 right heart failure hospitalization in red was associated with a mortality risk and a hazard ratio of 7 or more than 7 compared to patients who did not have right heart failure. So in controls, particularly early within the first 4 months after LVAD implantation, the presence of a right heart failure hospitalization was a very strong predictor of death. In contrast, what you can see on the right-hand side, amongst Revascor-treated patients, the risk of death, particularly in that early period 4-month period is almost completely abolish. And you can see that the overall survival over a 12-month period in Revascor-treated patient was the same, irrespective of whether they had a right heart failure hospitalization or not. So what this means is that Revascor not only reduces the incidence of hospitalization rates, but protects these patients against death from right heart failure. If you go to the next slide, please. So the summary of these new data, data that I haven't shown you here, but we have also observed is that Revascor reduces the inflammatory cytokines and through inflammation reduction protects the at-risk right ventricle in these patients, the same right ventricle that continues to fail despite the fact that there's an LVAD in the left ventricle. The strengthened right ventricle reduces hospitalization rates in the intensive care unit due to right heart failure and improves survival. The strengthened right ventricle decreases the risk of portal hypertension and therefore, decreases GI bleeding events. This leads us to think very carefully about how Revascor beyond its potential use in patients with left heart failure problems, also has the potential to be used to improve right heart failure function in patients not only with ischemic heart disease, but other causes of right heart failure, including primary pulmonary hypertension and chronic lung diseases. Next slide, please, Slide 26. So let me give you an update on our CHF program, particularly our plans to file for approval. With these new data and our existing orphan drug designation for treating this group of high-risk patients with high mortality as well as FDA's stated preference for randomized controlled trials, Mesoblast is moving from filing for an accelerated approval to filing for a full approval. Unlike an accelerated approval, full approval does not require a confirmatory study. Aligned with FDA on items required for filing the BLA regarding CMC potency assays for product release and commercial manufacturing, we now have these activities well and truly underway, and we expect to file our BLA for full approval for this indication in the next quarter. Let me summarize our highlights and our upcoming milestones. Ryoncil is the first and only FDA-approved MSC product. It delivered net revenues of USD 49 million in the first half of FY '26. As you heard, 49 centers have been onboarded, 64 centers account for 94% of the entire pediatric bone marrow transplant population, so well underway to achieve that in record time. We're initiating label expansion to adult acute GVHD, a market that is 3x larger than the pediatric market. We are currently prioritizing our portfolio, which includes the potential to go into the inflammatory bowel disease, neurodegenerative diseases and respiratory conditions, and we will update the market as we focus on certain areas in priority over others. Our second-generation rexlemestrocel-L is enrolling the second trial in back pain with full enrollment expected to complete by the end of March or end of April. BLA filing next quarter is in line for full approval for patients with right heart failure and end-stage heart failure with LVAD. And we're actively optimizing manufacturing logistics to support commercialization, both of the rexlemestrocel-L pipeline and obviously, to have further inventory for the projected growth in Ryoncil sales. With $130 million in cash on hand as of December 31 and the new credit line that you heard about, which still has the potential for $50 million available to draw down, we're in a very strong financial position. And as you heard earlier, we are projecting full year fiscal 2026 Ryoncil net revenue to range between USD 110 million and USD 120 million. And I think I'll stop there. And hopefully, there are some questions that we can all address. Thank you.
