Underlying profit (NPATA) was $2.02 billion1,2, up 13% on a constant currency basis to $2.06 billion1,2,3. Dr. Paul McKenzie, CSL's Chief Executive Officer and Managing Director said, "Our strong first-half result for the 2024 financial year was driven by CSL Behring's exceptional performance across its portfolio, especially immunoglobulins. The plasma initiatives we have implemented are starting to drive gross margin recovery. "CSL Seqirus achieved solid growth in a challenging season. Its portfolio of differentiated products outperformed the market. "For CSL Vifor we are well prepared for the transitioning iron market." PERFORMANCE CSL Behring Total revenue was $5,238 million, up 14%3 when compared to the prior comparable period. Immunoglobulin (Ig) product sales of $2,757 million, increased 23%3 with strong growth recorded across all geographies driven by global plasma supply and patient demand. PRIVIGEN® / INTRAGRAM® (Immune Globulin Intravenous (Human), 10% Liquid) sales grew 27%3 as the momentum from the prior year continued in improving product availability and patient diagnosis rates. HIZENTRA® (Immune Globulin Subcutaneous (Human), 20% Liquid) sales were up 18%3 driven by patient diagnosis rates. HIZENTRA® continues to be the clear market leader for subcutaneous immunoglobulin. Underlying demand for Ig continues to be strong due to significant patient needs in core indications – namely Primary Immune Deficiency, Secondary Immune Deficiency and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). Albumin sales of $613 million, were up 8%3. Sales were strong in emerging markets with solid growth in the US and Europe. Growth in China was modest, tempered by competitive pressure. Haemophilia product sales of $662 million increased 8%3. IDELVION®, CSL Behring's novel long-acting recombinant factor IX product achieved growth of 7%3 and continues to be the market leader in key markets. HEMGENIX®, the first and only gene therapy for haemophilia B was successfully launched in the US in FY23 and patient referrals have been accelerating. The haemophilia A market continued to be competitive resulting in a modest decline in sales for AFSTYLA®, a novel recombinant factor VIII product. Plasma-derived haemophilia products, however, achieved growth of 8% driven by HUMATE® / HAEMATE®, therapies for the treatment of patients with von Willebrand disease. Specialty products sales of $976 million, were up 6%3 led predominately by demand for KCENTRA® and HAEGARDA®. KCENTRA® (4 factor prothrombin complex concentrate) recorded sales growth of 12%3, as it continues to further penetrate the warfarin reversal market in the US. HAEGARDA®, our therapy for patients with Hereditary Angioedema, increased 9%, driven by the continued shift from on-demand to prophylaxis treatment and a strong performance in the UK and Europe. Garadacimab (Anti-FXIIa) for HAE, was filed for regulatory approval in the US and EU. Plasma Collections Plasma collections remain strong. The cost of collections, which includes donor compensation and labour, continued to trend down. A new roll out plan for the RIKA plasmapheresis devices was developed. Deployment across the US fleet is expected over the next 18 months. In addition, results from an individualised nomogram trial conducted by our supplier have been submitted for regulatory approval. CSL Seqirus Total revenue of $1,804 million, was up 2%3 driven by the adjuvanted influenza vaccine FLUAD®, which increased by 14%3. This growth was achieved against a backdrop of reduced rates of immunisation and highlights the strength of CSL Seqirus' differentiated product portfolio. During the period: Self-amplifying mRNA vaccine for COVID was approved by Japan's Ministry of Health, Labour and Welfare aQIVc, a next generation influenza vaccine combining adjuvant technology with cell-based manufacturing, enrolled its last patient in the Phase III clinical study in January 2024. CSL Vifor Total revenue was $1,011 million. The prior comparable period included only 5 months revenue following the acquisition of Vifor Pharma in August 2022. During the period: Preparations were made for the transitioning iron market There was strong performance from the long-acting erythropoiesis-stimulating agent, MIRCERA® TAVNEOS® was successfully launched in multiple European countries While the strategic potential of the business remains strong, we have dampened our near-term growth aspirations for CSL Vifor. Expense Performance Research and development (R&D) expenses were $669 million8 , up 11%3 when compared to the prior comparable period. The increase in expenses reflects higher costs associated with the progression of the R&D portfolio and investment in R&D infrastructure. Selling and marketing expenses (S&M) were $707 million8, up 2%3 in comparison to the prior comparable period. An additional month of CSL Vifor and an increase in labour costs accounts for the increase in S&M expenses while other S&M expenses were held in line with the prior comparable period. General and administrative (G&A) expenses were $323 million8, down 7%3 due to favourable foreign exchange differences and efficiencies generated from the centralisation of the group's Enabling Functions. Depreciation and amortisation (D&A) expense (excluding acquired intellectual property) was $297 million, up 1%3. Net finance costs were $234 million9, up 32%3. The increase in net finance costs was due to the debt associated with the acquisition of Vifor Pharma and higher interest rates. Financial position Cashflow from operations was $1,069 million, up 9%. The increase was driven by higher profitability and overall growth in sales. This was partly offset by higher payments for income tax and interest. Cash outflow from investing was $702 million, down significantly when compared to the prior comparable period as payment for the acquisition of Vifor Pharma was made in the prior period. CSL's balance sheet remains in a strong position with net assets of $19,162 million. Current assets increased by 10% to $10,146 million. The main driver was an increase in receivables due to the increase in sales and the seasonality of CSL Seqirus. Non-current assets increased by 1% to $27,158 million in comparison to the previous year. Current liabilities increased by 2% to $4,718 million. The increase in interest-bearing liabilities and borrowings (bank debt) was offset by the decrease in trade and other payables and current tax liabilities. Non-current liabilities decreased by 3% to $13,424 million. The decrease was due to the reclassification of certain bank borrowings as current, coupled with repayment across the Group's debt portfolio including the private placement senior notes. Outlook (at FY23 exchange rates) Commenting on CSL's outlook, Dr. McKenzie said, "For FY24, I am pleased to reaffirm our previous guidance. CSL's underlying profit, NPATA is expected be in the range of approximately $2.9 billion to $3.0 billion at constant currency3, representing growth over FY23 of approximately 13-17%[6]" "CSL is in a strong position to deliver annualised double-digit earnings growth over the medium term. "The strong growth in our immunoglobulins franchise is expected to continue as patient demand remains strong. "We have a number of initiatives underway in plasma collections that are improving efficiencies and processing times, supporting continued expansion in CSL Behring's gross margin. "Our transformational gene therapy product for haemophilia B patients, HEMGENIX®, is attracting significant interest from patients and health care professionals and patient referrals have accelerated. We expect more patients dosed in the second half of this financial year. "CSL Seqirus has performed well in a challenging season. However, due to the seasonality of this business we anticipate it to post a loss in the second half of the fiscal year. "For CSL Vifor, we are operating within an evolving iron market. While there are challenges for near-term growth, we are well positioned for iron competition in the EU and further geographic expansion. Our focus remains on unlocking value by leveraging capabilities across the CSL group", Dr. McKenzie concluded. In compiling the company's financial forecasts for FY24, a number of key variables that may have a significant impact on guidance have been identified and these have been included in the endnote[7].

HMB-001 was well tolerated with no drug-related adverse or thromboembolic events; dose-dependent improvements in blood-clotting activity support the potential of HMB-001 as a first-in-class prophylactic treatment for Glanzmann Thrombasthenia and other blood clotting disorders Preclinical HMB-001 findings were published in the February 2024 issue of Nature Cardiovascular Research COPENHAGEN, Denmark and CAMBRIDGE, Mass., Feb. 9, 2024 /PRNewswire/ -- Hemab Therapeutics, a clinical-stage biotechnology company developing novel prophylactic therapeutics for serious, underserved bleeding and thrombotic disorders, today presented initial results from Phase 1 of its ongoing evaluation of HMB-001. A novel bispecific antibody, HMB-001 is in development as a prophylactic treatment for the bleeding disorder Glanzmann Thrombasthenia (Glanzmann). The data were presented as one of 10 abstracts selected for the SLAM oral presentation session at the 17th Annual Congress of the European Association for Haemophilia and Allied Disorders (EAHAD) held this week in Frankfurt, Germany. "The first clinical data for HMB-001 in Glanzmann suggest that the demonstrated mechanism is suitable as a new prophylactic treatment for people with neglected blood clotting disorders who face severe, potentially life-threatening bleeds every day," said Joe Vogel, Senior Director and Program Lead for HMB-001 at Hemab. "With Phase 2 already underway, we are committed to advancing clinical evaluation of HMB-001 toward bringing life-changing preventative treatments to improve patients' quality of life." The Phase 1/2 first-in-human open-label study in patients with Glanzmann is evaluating the safety, tolerability, pharmacokinetics, and pharmacodynamics of HMB-001. As part of the UK-based Phase 1 single-ascending dose, seven patients received subcutaneous HMB-001 at 0.2 mg/kg, (n=1), 0.5 mg/kg (n=3) or 1.25 mg/kg (n=3). Over a 56-day observation period, HMB-001 was well tolerated; the most common adverse events (AEs) were mild or moderate in severity. No AEs or serious adverse events were deemed related to HMB-001. There were no dose-limiting toxicities and no thromboembolic events reported. Treatment with HMB-001 resulted in a dose-dependent pharmacodynamic effect of endogenous Factor VIIa accumulation that was associated with decreases in prothrombin time and improvement in exploratory thrombin generation analyses. The pharmacokinetic profile and half-life of HMB-001 support dosing every two weeks or a less-frequent dosing regimen. "People living with bleeding disorders like Glanzmann face devastating bleed events and considerable psychosocial impacts—from severe pain and social stigmatization to depression and isolation—but have no approved preventative treatments to turn to," said Suthesh Sivapalaratnam, MD, PhD, Queen Mary University of London, Barts Health NHS Trust. "These Phase 1 data support further investigation into the promise of HMB-001 for patients and providers across the globe who are awaiting innovation to improve the standard of care." Hemab has begun dosing and is actively enrolling in Phase 2, the multiple-ascending dose of the study, which will be expanded to sites across Europe and the U.S. For more information, visit clinicaltrials.gov (NCT06211634). In addition, Hemab announced that preclinical research findings of HMB-001 are now available online as part of the February 2024 issue of Nature Cardiovascular Research. The study results demonstrate the ability of HMB-001 to accumulate and potentiate the activity of endogenous Factor VIIa selectively on activated platelets, providing a sustained and localized procoagulant activity that may support prophylactic treatment of Glanzmann or other bleeding disorders. Read the paper here. About Glanzmann Thrombasthenia Glanzmann Thrombasthenia (Glanzmann) is a rare and severe bleeding disorder associated with debilitating and sometimes life-threatening bleeding episodes. Initial findings from the international Glanzmann's 360 (GT360) natural history study—Hemab's research initiative in partnership with UK specialist research consultancy Haemnet—found that 87% of the 104 respondents reported experiencing at least one bleed in the previous week, with 37% of those bleeds requiring medical treatment. These bleeding episodes significantly impact the mental health and quality of life of people living with Glanzmann. Low mood, emotional problems, and social isolation were reported by participants (66%, 50%, and 44% respectively), and 80% reported that they missed school or work due to bruising or bleeding. To date, there are no effective prophylactic treatment options for Glanzmann. About HMB-001 HMB-001 is bispecific antibody that binds and stabilizes endogenous Factor VIIa with one antibody arm and binds to TLT-1 on activated platelets with the other arm. This allows for accumulation of endogenous Factor VIIa in the body, recruitment of Factor VIIa directly to the surface of the activated platelets where it is known to facilitate clotting, and avoidance of clotting activity in the absence of tissue damage. HMB-001 is designed to be a first-in-class prophylactic treatment for Glanzmann Thrombasthenia with the potential to treat other debilitating rare bleeding disorders. The U.S. Food and Drug Administration granted Fast Track Designation to HMB-001 for the treatment of Glanzmann. About Hemab Therapeutics Hemab is a clinical-stage biotech company developing novel prophylactic therapeutics for serious, underserved bleeding and thrombotic disorders. Based in Cambridge, MA and Copenhagen, Denmark, Hemab is progressing a pipeline of monoclonal and bispecific antibody-based therapeutics to transform the treatment paradigm for patients with high unmet need. The company's strategic guidance, Hemab 1-2-5™, targets the development of 5 assets by 2025 to deliver long-awaited innovation for patients with high unmet need blood-clotting disorders like Glanzmann Thrombasthenia, Factor VII Deficiency, Von Willebrand Disease, and others.

WIL-31 is the largest prospective prophylaxis study in VWD WIL-31 is the only study in VWD with a prospective on-demand run-in study as an intra-individual comparator wilate® prophylaxis is highly effective at reducing bleeding rates in children and adults with all types of VWD vs prior on-demand treatment LACHEN, Switzerland, Jan. 22, 2024 /PRNewswire/ -- Octapharma announced today the publication of the results from the clinical study WIL-31, which investigated the efficacy and safety of prophylaxis with wilate ®, a von Willebrand factor/factor VIII (VWF/FVIII) concentrate, in patients with all types of von Willebrand disease (VWD). The results have been published in the leading medical journal Blood Advances [Sidonio RF Jr et al. "Von Willebrand factor/factor VIII concentrate (wilate®) prophylaxis in children and adults with von Willebrand disease"] The lead author and Principal Investigator of the WIL-31 study, Robert F. Sidonio Jr, M.D. (Medical Director of Hemophilia at the Aflac Cancer & Blood Disorders Center with Children's Healthcare of Atlanta and Associate Professor of Pediatrics at Emory University School of Medicine), commented: "WIL-31 is the largest prospective study to date examining the efficacy and safety of regular prophylaxis in patients with VWD. Importantly, the study included a diverse patient population, including young children and adults, males and females, and all types of VWD. The findings from WIL-31 provide strong evidence to support the use of VWF prophylaxis and have led to the recent addition of wilate ® prophylaxis as a therapeutic indication for VWD in the US, widening its access to the US patient population." The WIL-31 study (NCT04052698) was a prospective, multinational, open-label, non-controlled phase III study assessing wilate ® prophylaxis in preventing bleeds in VWD. Efficacy was assessed in 33 adult and pediatric VWD patients aged 6 years and older from 14 centers in eight countries, with patients receiving wilate ® prophylaxis two or three times weekly for 12 months. All patients had taken part in a prospective 6-month run-in study (WIL-29) during which they received on-demand treatment with any available VWF concentrate, allowing assessment of the efficacy of prophylaxis at an intra-individual level. The primary endpoint of the study, >50% reduction in mean total annualized bleeding rate (ABR) during wilate® prophylaxis compared with prior on-demand treatment, was met. Mean total ABR during wilate® prophylaxis was 5.2 compared with 33.4 during on-demand treatment, representing a decrease of 84%. Mean spontaneous ABR decreased by 87% during wilate® prophylaxis compared with on-demand treatment. Reductions in total and spontaneous bleeding were comparable across age groups, bleeding sites and VWD disease types, and between males and females. The majority of patients were dosed twice weekly and the median weekly dose of wilate® was relatively low (58 IU/kg) compared to the dose range recommended in the prescribing information. Seven women with child-bearing potential were included in the study. This allowed the investigators to gain insights into the effect of wilate® prophylaxis on heavy menstrual bleeding, which is a major problem in women with VWD as there are limited clinical data on effective treatments. Although the data are based on a small sample size, they suggest that wilate® prophylaxis has a positive impact in reducing heavy menstrual bleeding, with 71% (n=5) patients not experiencing heavy menstrual bleeding during wilate® prophylaxis. Prophylaxis with wilate® was well tolerated across VWD types, in children and adults, and in males and females. During the 12 months of wilate® prophylaxis, there were no serious adverse events related to wilate® and no thrombotic events or FVIII accumulation. "In contrast to haemophilia A, prophylaxis is not standard of care in VWD and less than 10% of patients with severe VWD receive prophylaxis", said Sigurd Knaub, SVP CR&D Haematology. "This is due in part to the scarcity of data from prospective trials. The results of the WIL-31 study help to fill this gap, providing strong evidence for the benefits of a prophylactic strategy in patients with severe VWD. Increasing the adoption of prophylaxis in VWD is expected to lead to improved outcomes and reduced disease burden for people suffering from VWD." Octapharma would like to thank all participating centers, as well as the patients and their caregivers, for their contribution to the study. Further publications on other analyses from the WIL-31 study are planned. About wilate® wilate® is a high-purity human von Willebrand factor/factor VIII (VWF/FVIII) concentrate, that undergoes two virus inactivation steps during its production1. No albumin is added as a stabiliser1. The purification processes result in a 1:1 ratio of VWF to FVIII that is similar to normal plasma1. wilate® contains a VWF triplet structure and content of large high molecular weight multimers similar to normal human plasma1. wilate® is available in 500 IU and 1,000 IU presentations2. wilate® is indicated for the prevention and treatment of haemorrhage or surgical bleeding in von Willebrand disease (VWD), when desmopressin (DDAVP) alone is ineffective or contra-indicated, and for the treatment and prophylaxis of bleeding in patients with haemophilia A (congenital factor VIII deficiency)2.
