FRONTIER2 data presented at ISTH 2024 showed that up to 95% of people, who had no prior prophylaxis treatment, experienced zero treated bleeds while on Mim8 BAGSVAERD, Denmark I June 23, 2024 I Novo Nordisk announced results from the phase 3 FRONTIER2 trial of 254 adults and adolescents aged 12 years and over with haemophilia A, with and without inhibitors. The trial assessed both once-weekly and once-monthly prophylactic treatment (regular treatment to prevent prolonged and spontaneous bleeding) with the investigational treatment Mim8. The data were presented at the International Society of Thrombosis and Haemostasis Annual Congress (ISTH 2024) in Bangkok, Thailand. In the trial population with no prior prophylaxis treatment: In the trial population with prior coagulation factor prophylaxis: “Despite treatment advances, there are still many unmet needs for people living with haemophilia A,” said FRONTIER2 lead investigator Dr Maria Elisa Mancuso, Senior Consultant in Haematology, Centre for Thrombosis and Haemorrhagic Diseases, IRCCS Humanitas Research Hospital, Milan, Italy. “The FRONTIER2 data demonstrated superiority of Mim8 prophylaxis over both on demand treatment and prior clotting factor prophylaxis with respect to the number of treated bleeding episodes in people living with haemophilia A, regardless of their inhibitor status. It is also encouraging to see that in some subgroups in the study, up to 95% of people treated with Mim8 experienced zero bleeds.” Mim8 is a next-generation Factor VIIIa (FVIIIa) mimetic bispecific antibody designed with the potential to deliver sustained haemostasis. It is currently in development for once-weekly or once-monthly prophylaxis treatment for people living with haemophilia A, with and without inhibitors. Administered subcutaneously, Mim8 bridges Factor IXa/X (FIXa/FX), thereby replacing missing FVIII. This restores the body’s thrombin generation capacity, helping blood to clot. 1 In this trial, Mim8 was well-tolerated, and no safety concerns (thromboembolic events or related serious adverse events) were observed, in line with previous findings. “The FRONTIER2 efficacy and safety data is very encouraging,” said Martin Holst Lange, Executive Vice President of Development at Novo Nordisk. “With Mim8, we have the potential of offering a substantial proportion of patients the prospect of zero bleeds and convenient dosing flexibility to fit their lifestyles and needs. We look forward to discussing these data with regulatory authorities.” Contingent on regulatory interactions, Novo Nordisk aims to submit Mim8 for the first regulatory approval towards the end of 2024. Data from the ongoing phase 3 FRONTIER programme will continue to be disclosed at upcoming congresses and in publications in 2024 and 2025. About Haemophilia Haemophilia is a rare inherited bleeding disorder that impairs the body’s ability to make blood clots, a process needed to stop bleeding. It is estimated to affect approximately 1,125,000 people worldwide, and haemophilia A is estimated to account for 80-85% of all haemophilia cases. 2 Due to the nature of haemophilia being a rare x-linked recessive disorder, it often presents differently in males compared to females, with ~ 88% of people diagnosed with haemophilia worldwide being male. 3,4 There are different types of haemophilia, which are characterised by the type of clotting factor protein that is defective or missing. Haemophilia A is caused by a missing or defective clotting Factor VIII (FVIII). Some people with haemophilia may also develop inhibitors, which are an immune system response to the clotting factors in replacement therapy that cause treatment to stop working. Currently, it is estimated that up to 30% of people living with severe haemophilia A have inhibitors. 5 About the FRONTIER2 clinical trial The FRONTIER phase 3 clinical development programme investigates Mim8 as a prophylactic treatment for people with haemophilia A, with or without inhibitors. The phase 3 programme includes FRONTIER2 6 , FRONTIER3 7 , FRONTIER4 8 , and FRONTIER5 9 . FRONTIER2 is a 52-week efficacy and safety phase 3 trial, comparing once-weekly and once-monthly Mim8 versus no prophylaxis and versus prior coagulation factor prophylaxis (26-52-week run-in period) in people aged 12 years and over with haemophilia A, with or without inhibitors. The 26-week main phase of the trial is completed, a 26-week extension phase is ongoing. Participants were randomised into five treatment arms: Those who had received on-demand treatment prior to trial enrolment: Those who had received prophylaxis treatment prior to trial enrolment: About Novo Nordisk Novo Nordisk is a leading global healthcare company, founded in 1923 and headquartered in Denmark.

Phase III HAVEN 7 primary data presented at ASH 2023 provide additional confidence in the favourable efficacy and safety profile of subcutaneous Hemlibra given soon after birth 1At nearly two years median follow-up in the descriptive, single-arm study, no babies experienced spontaneous bleeds requiring treatment, and all treated bleeds were as a result of trauma 1Safety results were consistent with previous studies of Hemlibra, with no new safety signals observed 1The HAVEN 7 study was developed in collaboration with the haemophilia A community, to generate additional evidence for the prophylactic treatment of infants with haemophilia A Basel, 09 December 2023 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that the primary analysis of the Phase III HAVEN 7 study reinforced the efficacy and safety of Hemlibra® (emicizumab) in previously untreated or minimally treated infants with severe haemophilia A without factor VIII inhibitors. Results showed that Hemlibra achieved meaningful bleed control in babies up to 12 months of age, and was well tolerated.1 The new data were presented at the 65th American Society of Hematology (ASH) Annual Meeting and Exposition taking place 9-12 December 2023, in San Diego, California, and included in the press programme. “Haemophilia A can have a devastating impact on any patient, but this is especially true for infants, where the emotional and physical stress due to frequent hospital visits, treatment administration and other worries can be distressing for babies and their parents and caregivers,” said Steven Pipe, MD, professor of paediatrics and pathology at the University of Michigan. “These results reinforce the benefit of starting prophylaxis as soon as possible after birth, as well as for the use of subcutaneous treatments, which are especially valuable in young babies where access to veins can be very difficult.” The burden of severe haemophilia A in babies and on their parents and caregivers is significant. The World Federation of Haemophilia treatment guidelines consider the standard of care in haemophilia to be regular prophylaxis initiated at a young age, as studies have shown this improves long-term outcomes, while reducing the risk of intracranial haemorrhage.[2-4] However, for many babies with haemophilia A, prophylaxis is not started until after the first year of life because of the high treatment burden.[5-8] Hemlibra, which is already approved and being used to treat babies with haemophilia A, provides a flexible treatment option that can be administered subcutaneously from birth at different dosing frequencies.9 “The results of HAVEN 7 provide additional confidence in the efficacy and safety profile of Hemlibra for babies with severe haemophilia A, and add to its extensive clinical and real-world evidence across all ages,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “Conducted in collaboration with the haemophilia A community, this trial reflects our ongoing commitment to listen and respond to the needs of those impacted by this condition, in hopes of advancing treatment standards even further.” The HAVEN 7 study is a Phase III, descriptive, single-arm study, set up in collaboration with the haemophilia A community to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of subcutaneous Hemlibra in infants with severe haemophilia A without factor VIII inhibitors. These results, which included data from 55 participants, showed that at 101.9 weeks median follow-up, 54.5% of participants (n=30) did not have any bleeds that required treatment, while 16.4% (n=9) did not have any treated or untreated bleeds at all. There were no spontaneous bleeds requiring treatment in any participant, and all treated bleeds were as a result of trauma. A total of 207 bleeds occurred in 46 participants (83.6%); 87.9% of these were as a result of trauma. Model-based annualised bleeding rate (95% CI) was 0.4 (0.30–0.63) for treated bleeds. No new safety signals were observed and there were no treatment-related serious adverse events, intracranial haemorrhages or deaths reported. Just 3.6% of participants (n=2) tested positive for factor VIII inhibitors, which may be a consequence of reduced factor VIII usage in participants treated with Hemlibra, and no participant tested positive for anti-drug antibodies.[1] Results were consistent with positive results from the interim analysis and from previous Phase III HAVEN studies.10-14 The results of additional research on biomarkers in the HAVEN 7 study were also presented at ASH, and were supportive of the study’s primary efficacy analysis. This additional research showed that the pharmacodynamic profiles of Hemlibra in babies were consistent with those previously observed in older children and adults with haemophilia A. The data showed that Hemlibra exhibits the expected pharmacodynamic response, despite the reduced presence of the clotting factors that Hemlibra binds to in this age group.15 The Phase III HAVEN 7 study results complement data from the broader, pivotal HAVEN clinical programme, providing insights into the evolution of haemophilia A in babies, and the impact of initiating preventative treatment from birth. The primary analysis is being followed by a seven year extension period.1 Hemlibra continues to redefine standards of care in haemophilia A, as a flexible treatment option approved across all ages and stages of life, regardless of inhibitor status and at different dosing frequencies. It is approved for the routine prophylaxis of people with haemophilia A in more than 115 countries worldwide. It has been studied in one of the largest clinical trial programmes in people with haemophilia A with and without factor VIII inhibitors, including eight Phase III studies.About Hemlibra® (emicizumab) Hemlibra is a bispecific factor IXa- and factor X-directed antibody. It is designed to bring together factor IXa and factor X, proteins involved in the natural coagulation cascade, and restore the blood clotting process for people with haemophilia A. Hemlibra is a prophylactic (preventative) treatment that can be administered by an injection of a ready-to-use solution under the skin (subcutaneously) once-weekly, every two weeks, or every four weeks (after an initial once-weekly dose for the first four weeks).9 Hemlibra was created by Chugai Pharmaceutical Co., Ltd. and is being co-developed globally by Chugai, Roche and Genentech. It is marketed in the United States by Genentech as Hemlibra (emicizumab-kxwh), with kxwh as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the U.S. Food and Drug Administration. About haemophilia A Haemophilia A is an inherited, serious disorder in which a person’s blood does not clot properly, leading to uncontrolled and often spontaneous bleeding. Haemophilia A affects around 900,000 people worldwide.2,16 The burden of severe haemophilia A in infants and on their parents and caregivers is significant. People with haemophilia A either lack or do not have enough of a clotting protein called factor VIII. In a healthy person, when a bleed occurs, factor VIII brings together the clotting factors IXa- and X, which is a critical step in the formation of a blood clot to help stop bleeding. Depending on the severity of their symptoms, people with haemophilia A can bleed frequently, especially into their joints or muscles.17 These bleeds can present a significant health concern as they often cause pain and can lead to chronic swelling, deformity, reduced mobility and long-term joint damage.18 A serious complication of treatment is the development of inhibitors to factor VIII replacement therapies. Inhibitors are antibodies developed by the body’s immune system that bind to and block the efficacy of replacement factor VIII, making it difficult, if not impossible, to obtain a level of factor VIII sufficient to control bleeding.2 About Roche in haematologyRoche has been developing medicines for people with malignant and non-malignant blood diseases for more than 20 years; our experience and knowledge in this therapeutic area runs deep.

About Hemlibra Hemlibra is a bispecific factor IXa- and factor X-directed antibody. It is designed to bring together factor IXa and factor X, proteins required to activate the natural coagulation cascade and restore the blood clotting process for hemophilia A patients. Hemlibra is a prophylactic (preventative) treatment that can be administered by an injection of a ready-to-use solution under the skin (subcutaneously) once weekly, every two weeks or every four weeks. Hemlibra was created by Chugai Pharmaceutical Co., Ltd. and is being co-developed globally by Chugai, Roche and Genentech. Hemlibra U.S. Indication Hemlibra is a prescription medicine used for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children, ages newborn and older, with hemophilia A with or without factor VIII inhibitors. Important Safety Information What is the most important information to know about Hemlibra? Hemlibra increases the potential for blood to clot. People who use activated prothrombin complex concentrate (aPCC; Feiba ® ) to treat breakthrough bleeds while taking Hemlibra may be at risk of serious side effects related to blood clots. These serious side effects include: Thrombotic microangiopathy (TMA), a condition involving blood clots and injury to small blood vessels that may cause harm to one’s kidneys, brain, and other organs Blood clots (thrombotic events), which may form in blood vessels in the arm, leg, lung, or head Patients should talk to their doctor about the signs and symptoms of these serious side effects, which can include Confusion Stomach, chest, or back pain Weakness Nausea or vomiting Swelling, pain, or redness Feeling sick or faint Decreased urination Swelling of arms and legs Yellowing of skin and eyes Eye pain, swelling, or trouble seeing Fast heart rate Numbness in your face Headache Shortness of breath Coughing up blood If patients experience any of these symptoms during or after treatment with Hemlibra, they should get medical help right away. Patients should carefully follow their healthcare provider’s instructions regarding when to use an on demand bypassing agent or factor VIII, and the dose and schedule to use for breakthrough bleed treatment. If aPCC (Feiba ® ) is needed, patients should talk to their healthcare provider in case they feel they need more than 100 U/kg of aPCC (Feiba ® ) total. Patients’ bodies may make antibodies against Hemlibra, which may stop Hemlibra from working properly. Patients should contact their healthcare provider immediately if they notice that Hemlibra has stopped working for them (e.g., increase in bleeds). The most common side effects of Hemlibra include : injection site reactions (redness, tenderness, warmth, or itching at the site of injection), headache, and joint pain. These are not all of the possible side effects of Hemlibra. Patients can speak with their healthcare provider for more information. What else should patients know about Hemlibra? Patients should see the detailed “Instructions for Use” that comes with Hemlibra for information on how to prepare and inject a dose of Hemlibra, and how to properly throw away (dispose of) used needles and syringes. Patients should stop taking their prophylactic bypassing therapy the day before they start Hemlibra Patients may continue taking their prophylactic factor VIII for the first week of Hemlibra Hemlibra may interfere with laboratory tests that measure how well blood is clotting and create an inaccurate result. Patients should speak with their healthcare provider about how this may affect their care. Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. Patients should only use Hemlibra for the condition it was prescribed. Patients should not give Hemlibra to other people, even if they have the same symptoms that they have. It may harm them. Patients should tell their healthcare provider about all the medicines they take, including prescription medicines, over-the-counter medicines, vitamins, or herbal supplements. Patients should keep a list of them to show their healthcare provider and pharmacist. Before using Hemlibra, patients should tell their healthcare provider about all of their medical conditions, including if they are pregnant, plan to become pregnant, are breastfeeding, or plan to breastfeed. Since Hemlibra was tested in males, there is no information on whether Hemlibra may impact an unborn baby or breast milk. Females who are able to become pregnant should use birth control during treatment. Side effects may be reported to the FDA at (800) FDA-1088 or http://www.fda.gov/medwatch . Side effects may also be reported to Genentech at (888) 835-2555. Please see Important Safety Information, including Serious Side Effects, as well as the Hemlibra full Prescribing Information and Medication Guide . About hemophilia A Hemophilia A is an inherited, serious disorder in which a person’s blood does not clot properly, leading to uncontrolled and often spontaneous bleeding. Hemophilia affects around 20,000 people in the United States, with hemophilia A being the most common form and approximately 50-60% of people living with a severe form of the disorder. People with hemophilia A either lack or do not have enough of a clotting protein called factor VIII. In a healthy person, when a bleed occurs, factor VIII brings together the clotting factors IXa and X, which is a critical step in the formation of a blood clot to help stop bleeding. Depending on the severity of their disorder, people with hemophilia A can bleed frequently, especially into their joints or muscles. These bleeds can present a significant health concern as they often cause pain and can lead to chronic swelling, deformity, reduced mobility and long-term joint damage. A serious complication of treatment is the development of inhibitors to factor VIII replacement therapies. Inhibitors are antibodies developed by the body’s immune system that bind to and block the efficacy of replacement factor VIII, making it difficult, if not impossible, to obtain a level of factor VIII sufficient to control bleeding.
