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.

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.

Octapharma is Committed to Supplying Hospitals and Medical Providers with New Prothrombin Complex Concentrate PARAMUS, N.J., Jan. 3, 2024 /PRNewswire/ -- Octapharma USA has announced Balfaxar® (prothrombin complex concentrate, human-lans; marketed in Europe and Canada as octaplex®) is now available. The new non-activated four factor prothrombin complex concentrate (4F-PCC), approved by the U.S. Food and Drug Administration (FDA) this summer, is indicated for the urgent reversal of acquired coagulation factor deficiency induced by vitamin K antagonist (VKA, e.g., warfarin) therapy in adult patients with need for urgent surgery or invasive procedures. Continue Reading Octapharma has the Balfaxar® production flexibility to ensure consistent supply for hospitals and medical providers. Post this Octapharma USA has announced Balfaxar® (prothrombin complex concentrate, human-lans; marketed in Europe and Canada as octaplex®) is now available. Balfaxar®, a lyophilized powder for reconstitution, will be provided with sterile water for injection and the new transfer device, nextaro®. "The availability of Balfaxar® brings a welcome new treatment option for medical providers around the country," said Josh Goldstein, MD, PhD, Professor of Emergency Medicine at Harvard Medical School and Massachusetts General Hospital. "More than 2.4 million U.S. patients are prescribed warfarin to prevent blood clots from forming in patients who are at high risk.1 Unfortunately, the main side effect of warfarin is an increased risk of bleeding, which can complicate urgent surgery or invasive procedures.2 Clinical research has demonstrated that Balfaxar® is extremely effective in restoring blood coagulation by replenishing the levels of clotting factors that are deficient in those patients on warfarin." Balfaxar® is a non-activated 4F-PCC containing vitamin K-dependent factors: Factor II (prothrombin), Factor VII, Factor IX and Factor X, as well as antithrombotic Proteins C and S. "We are excited to announce the availability of Balfaxar® and are committed to providing the medical community with a valuable life-saving therapy," said Octapharma USA President Flemming Nielsen. "Octapharma has the production flexibility to ensure consistent supply for hospitals and medical providers now and in the future. We look forward to working with our critical care medicine partners to ensure patients receive the absolute best treatments available." The FDA approval of Balfaxar® was supported by the clinical trial LEX-209 (ClinicalTrials.gov Identifier: NCT02740335), which compared the efficacy and safety of Balfaxar® head-to-head with a control 4F-PCC (Kcentra®). The Phase III, randomized, double-blind, multicenter study randomized 208 patients to Balfaxar® (N=105) or control 4F-PCC (N=103). Balfaxar® met the primary endpoint of hemostatic efficacy in patients on a vitamin K antagonist undergoing urgent surgery with significant bleeding risk. The primary objective was met at the prespecified interim analysis and the study was stopped due to statistically significant efficacy results. Balfaxar® demonstrated effective hemostasis in 94.6% of patients versus 93.5% of patients for Kcentra®. International Normalized Ratio (INR) reductions and vitamin K dependent coagulation factor increases supported the primary endpoint and PCC dosing and duration of infusion were also similar. The safety profile was similar between treatment arms and consistent with previous studies.3 To study Balfaxar® further in other clinical scenarios, Octapharma is recruiting for two additional Phase III studies: LEX-210: Study of OCTAPLEX in Patients With Acute Major Bleeding on DOAC Therapy With Factor Xa Inhibitor (ClinicalTrials.gov Identifier: NCT04867837) LEX-211: Active-control Randomised Trial Comparing 4-factor Prothrombin Complex Concentrate With Frozen Plasma in Cardiac Surgery (ClinicalTrials.gov Identifier: NCT05523297) For more information on LEX-210 and LEX-211, please visit ClinicalTrials.gov. Kcentra® is a registered trademark of CSL Behring GmbH. For more information on Balfaxar®, please contact Octapharma customer service at 201-604-1130. About Balfaxar® Balfaxar® (prothrombin complex concentrate, human-lans) is a blood coagulation factor replacement product indicated for the urgent reversal of acquired coagulation factor deficiency induced by Vitamin K antagonist (VKA, e.g., warfarin) therapy in adult patients with need for an urgent surgery/invasive procedure. WARNING: ARTERIAL and VENOUS THROMBOEMBOLIC COMPLICATIONS Patients being treated with Vitamin K antagonists (VKA) therapy have underlying disease states that predispose them to thromboembolic events. Potential benefits of reversing VKA should be weighed against the potential risks of thromboembolic events, especially in patients with the history of a thromboembolic event. Resumption of anticoagulation should be carefully considered as soon as the risk of thromboembolic events outweighs the risk of acute bleeding. Both fatal and non-fatal arterial and venous thromboembolic complications have been reported with Balfaxar® in clinical trials and post marketing surveillance. Monitor patients receiving Balfaxar® for signs and symptoms of thromboembolic events. Balfaxar® may not be suitable in patients with thromboembolic events in the prior 3 months.

HMB-001 is a novel bispecific antibody designed to be the first prophylactic treatment for Glanzmann Thrombasthenia (GT) and other debilitating bleeding disorders Phase 1 was successfully completed in the UK; Hemab plans additional sites in Europe and the U.S. for Phase 2 The U.S. FDA has cleared the Investigational New Drug (IND) application and granted Fast Track Designation to HMB-001 for the treatment of GT COPENHAGEN, Denmark and CAMBRIDGE, Mass., Dec. 11, 2023 /PRNewswire/ -- Hemab Therapeutics, a clinical-stage biotechnology company developing novel prophylactic therapeutics for serious, underserved bleeding and thrombotic disorders, announced today that it has completed Phase 1, the single ascending dose part, and transitioned to Phase 2, the multiple ascending dose part, of its Phase 1/2 clinical study of HMB-001 in Glanzmann Thrombasthenia (GT), a platelet disorder that causes severe, potentially life-threatening bleeding episodes. The company also announced that the U.S. Food and Drug Administration (FDA) has cleared Hemab's investigational new drug application (IND) for HMB-001 in GT, enabling enrollment in the U.S. Phase 1 of the clinical study was completed in the UK, and Phase 2 will include additional sites in Europe as well as the U.S. In addition, the FDA granted Fast Track designation to HMB-001, emphasizing the seriousness and high unmet need for treatments for GT. The Fast Track program enables Hemab to have more frequent interactions with the FDA to facilitate the development of HMB-001. "People living with Glanzmann Thrombasthenia can experience frequent, sometimes severe bleeds that can be life-threatening and compromise their quality of life. Currently, there are no prophylactic treatment options that would reduce or prevent these bleeding episodes," said Benny Sorensen, MD, PhD, CEO of Hemab. "The completion of Phase 1 on time and transitioning to Phase 2 is an important milestone for HMB-001 and Hemab. Furthermore, expanding our clinical study into the U.S., following clearance of the IND, and Fast Track designation are a testament to the importance of advancing prophylactic treatment for people living with Glanzmann Thrombasthenia." The Phase 1/2 clinical study evaluates the safety, tolerability, pharmacodynamics, and pharmacokinetics of HMB-001. Initial efficacy signals based on an assessment of changes in bleeding frequency will also be measured. The study is composed of three parts: Part A, single ascending dose, Part B, multiple ascending dose, and Part C, extended dosing. Hemab plans to report data from the Phase 1, single ascending dose portion, at an international scientific conference in early 2024. The Phase 1/2 study design was detailed in the company's poster presentation (number 1225), "A Phase 1/2, First-in-Human, Study to Investigate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of HMB-001 in Participants with Glanzmann Thrombasthenia," at the 65th American Society of Hematology Annual Meeting and Exposition.
