Concizumab-mtci

The FDA cleared additional indications for Novartis’s cholesterol-lowering drug Leqvio (inclisiran) and Novo Nordisk's haemophilia prophylactic Alhemo (concizumab-mtci), broadening their use to wider patient populations.Leqvio gets go-ahead as montherapyNovartis's twice-yearly injectable siRNA drug Leqvio was approved by the FDA as monotherapy alongside diet and exercise to lower low-denisty lipoprotein cholesterol (LDL-C) in adults with hypercholesterolaemia, thereby eliminating the previous requirement for concurrent statin therapy.“With this new indication enabling Leqvio's use as monotherapy…we now have the potential to help even more patients achieve their LDL-C lowering goals earlier in their treatment journey," said Victor Bultó, president of Novartis US.The US regulator said Leqvio’s broader indication was approved based on strong LDL-C-lowering data from PCSK9-targeting therapies. Additional label updates include replacing "primary hyperlipidaemia" terminology with the more specific "hypercholesterolaemia" designation throughout the prescribing information.Novartis noted the decision also aligns with the 2025 American College of Cardiology/American Heart Association Clinical Practice Guidelines, recommending more aggressive treatment approaches for patients with acute coronary syndrome.Leqvio was discovered by Alnylam and co-developed with The Medicines Company, which Novartis acquired in 2020 for $9.7 billion. First approved in the EU for hypercholesterolaemia or mixed dyslipidaemia in 2020, the siRNA’s US approval faced initial delays owing to manufacturing issues, but was subsequently cleared by the FDA in 2021 for patients on maximally tolerated statin therapy.The Swiss drugmaker expects Leqvio not only to surpass $1 billion in sales this year, but potentially outperform consensus forecasts long term.

The latest approval builds upon the tissue factor pathway (TFPI) inhibitor antagonist’s approval last year for patients with inhibitors after being rejected by the agency on the first attempt.Anna Windle, senior VP of clinical development, medical & regulatory affairs at Novo Nordisk, said the latest approval “marks a meaningful step forward for people with haemophilia A or B without inhibitors who are looking for a new prophylaxis treatment option."The label expansion was supported by the Phase III explorer8 study, wherein Alhemo achieved an 86% reduction in annualised bleeding rate for patients with haemophilia A and 79% reduction for those with haemophilia B versus no prophylaxis.Following a positive recommendation by the EU drug advisory body last week, the anti-TFPI monoclonal antibody is also on the verge of approval in Europe for the same indication.With the additional indication, Alhemo emerges as a potential rival to Pfizer’s once-weekly Hympavzi (marstacimab-hncq), approved last year for patients without inhibitors. Pfizer also seeks Hympavzi’s expansion to patients with inhibitors following a successful Phase III study.

FDA approval is based on phase 3 trial data (explorer8), which established the safety and efficacy of Alhemo® (concizumab-mtci) injection in people 12 years and older with hemophilia A or B (HA/HB) without inhibitors1 Results showed a 79% reduction in annualized bleeding rate (ABR) in patients with HB without inhibitors and an 86% reduction in patients with HA without inhibitors, respectively, using Alhemo® prophylaxis compared to no prophylaxis2 Alhemo® was the first subcutaneous injectable pen of its kind for patients living with HA and HB with inhibitors and is now approved for those living without inhibitors1 PLAINSBORO, N.J., July 31, 2025 /PRNewswire/ -- Novo Nordisk announced today that the US Food and Drug Administration (FDA) approved Alhemo® (concizumab-mtci) injection as a once-daily prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients 12 years of age and older with hemophilia A or B (HA/HB) without inhibitors, expanding on the December 2024 approval for HA/HB with inhibitors.1,2,3 Currently, many treatments for HA/HB without inhibitors are administered via intravenous infusions.2 With this approval, Alhemo® now offers a subcutaneous injection treatment option for this population.1 "The FDA approval of an expanded indication for Alhemo® marks a meaningful step forward for people with hemophilia A or B without inhibitors who are looking for a new prophylaxis treatment option," said Anna Windle, PhD, Senior Vice President, Clinical Development, Medical & Regulatory Affairs, Novo Nordisk. "By building on the initial indication for Alhemo® for those with hemophilia with inhibitors—an especially significant development in hemophilia B where challenges still exist despite advanced treatment options—Novo Nordisk continues its 35+ year legacy in rare bleeding disorders to continue to help address the unmet needs of this community." Alhemo® is designed to block a protein called tissue factor pathway inhibitor (TFPI), which stops blood from clotting. By inhibiting TFPI, Alhemo® improves the production of thrombin, which helps to clot the blood and prevent bleeding, when clotting factors VIII and IX are missing or deficient regardless of inhibitor status.4,5 "For people living with hemophilia, it is important to continually monitor and discuss bleed control with their healthcare professional," said Allison P. Wheeler, MD, Scientific Director, Washington Center for Bleeding Disorders, Seattle, WA. "With today's approval of Alhemo® for hemophilia A or B without inhibitors, more people living with these rare blood disorders now have a daily prophylaxis option that may help decrease their bleeding rates." The primary objective of the pivotal phase 3 explorer8 trial was to compare the number of treated spontaneous and traumatic bleeding episodes, as measured by the ABR, in patients aged 12 years and older with HA/HB without inhibitors, receiving Alhemo® prophylaxis versus no prophylaxis (on demand Factor VIII/Factor IX treatment).2 The study showed a statistically significant reduction in ABR of 79% for HB patients (ABR ratio: 0.21; 95% CI: 0.10–0.45; p<0.0001) and 86% for HA patients (ABR ratio: 0.14; 95% CI: 0.07–0.29; p<0.0001). Additionally, notable reductions in the average and median ABRs further reinforced the efficacy of Alhemo® prophylaxis in reducing bleeds across both patient groups, with an average ABR of 3.1 (1.9-5.0) and a median ABR of 1.6 (0.0-4.8) for HB patients, compared to 14.8 (8.1-26.9) and 14.9 (3.3-22.1), respectively, and an average ABR of 2.7 (1.6-4.6) and median ABR of 2.9 (0.0-5.2) for HA patients, compared to 19.3 (11.3-33.0) and 19.6 (17.3-30.4), respectively. In the study, the most common adverse reactions reported in ≥5% of patients randomized to receive Alhemo® were injection site reactions (7%) and headache (7%).1 Alhemo® is provided in prefilled, premixed pens for subcutaneous injection (60 mg/1.5 mL, 150 mg/1.5 mL, or 300 mg/3 mL) via thin 32 gauge, 4 mm needles, which are provided separately, offering an additional treatment choice for patients with hemophilia with inhibitors – and now without inhibitors – to further customize their care. About the explorer8 study Explorer8 is a phase 3 clinical trial that evaluated the efficacy and safety of Alhemo® for adults and pediatric patients 12 years of age and older living with hemophilia A or B (HA/HB) without inhibitors.2 In explorer8, among the 156 males with HA/HB included in the trial, 63 were randomly assigned in a 1:2 ratio to receive no prophylaxis (arm 1, n=21), or Alhemo® prophylaxis (arm 2, n=42).2,6 The median duration of treatment was 24.1 weeks in arm 1 (no prophylaxis) and 32.1 weeks in arm 2 (Alhemo® prophylaxis).The initial loading dose of Alhemo® was 1 mg per kilogram of body weight, followed by 0.2 mg per kilogram daily, and potentially individualized on the basis of concizumab-mtci plasma concentration as measured at week 4.1,2 Efficacy was evaluated separately in HA patients without inhibitors and in HB patients without inhibitors when all patients in arms 1 and 2 had completed the main part of the trial (at least 24 or at least 32 weeks, respectively), based on the number of treated bleeding episodes comparing Alhemo® prophylaxis and no prophylaxis.1 About Alhemo® (concizumab-mtci) Alhemo® is a tissue factor pathway inhibitor (TFPI) antagonist. By inhibiting the TFPI, Alhemo® enhances factor Xa (FXa) production during the initiation phase of coagulation, leading to improved thrombin generation and clot formation in patients with hemophilia A or B (HA/HB) with or without inhibitors. The effect of Alhemo® is not influenced by the presence of inhibitory antibodies to FVIII or FIX and Alhemo® does not induce or enhance the development of direct inhibitors to FVIII or FIX. Alhemo® is approved as a once-daily prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and pediatric patients 12 years of age and older with HA/HB with or without inhibitors in the US.1 What is Alhemo®? Alhemo® (concizumab-mtci) injection 60 mg, 150 mg, or 300 mg is a prescription medicine used for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children 12 years of age and older with hemophilia A or B with or without factor VIII or IX inhibitors. It is not known if Alhemo® is safe and effective in people receiving ongoing immune tolerance induction (ITI) or in children younger than 12 years of age Important Safety Information What is the most important information I should know about Alhemo®? It is important to follow the daily dosing schedule of Alhemo® to stay protected against bleeding. This is especially important during the first 4 weeks of treatment to make sure a correct maintenance dose is established. Use Alhemo® exactly as prescribed by your healthcare provider (HCP). Do not stop using Alhemo® without talking to your HCP. If you miss doses or stop using Alhemo®, you may no longer be protected against bleeding Your HCP may prescribe factor VIII, factor IX, or bypassing agents during treatment with Alhemo®. Carefully follow your HCP's instructions regarding when to use on-demand factor VIII, factor IX, or bypassing agents and the recommended dose and schedule for breakthrough bleeds Do not use Alhemo® if you are allergic to concizumab-mtci or any of the ingredients in Alhemo®. Before using Alhemo®, tell your HCP about all of your medical conditions, including if you: Have a planned surgery. Talk to your HCP about when to stop using Alhemo® and when to start it again if you have a planned surgery Are pregnant, breastfeeding, or plan to become pregnant or breastfeed. It is not known if Alhemo® may harm your unborn baby or if Alhemo® passes into your breast milk Your HCP may do a pregnancy test before you start treatment with Alhemo® Females who are able to become pregnant, talk to your HCP about using effective birth control (contraception) methods during treatment with Alhemo® and for 7 weeks after ending treatment Tell your HCP about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and supplements. What are the possible side effects of Alhemo®? Alhemo® may cause serious side effects, including: Blood clots (thromboembolic events). Alhemo® may cause blood clots to form in blood vessels, such as in your arms, legs, heart, lung, brain, eyes, kidneys, or stomach. You may be at risk for getting blood clots if you use high or frequent doses of factor products or bypassing agents to treat breakthrough bleeds, or if you have certain conditions. Get medical help right away if you have any signs and symptoms of blood clots, including: swelling, warmth, pain, or redness of the skin; headache; trouble speaking or moving; eye pain or swelling; sudden pain in your stomach or lower back area; feeling short of breath or severe chest pain; confusion; numbness in your face; and problems with your vision Allergic reactions.

Hemophilia A is caused by a missing or defective clotting Factor VIII (FVIII), and hemophilia B is caused by a missing or defective clotting Factor IX (FIX).7 Hemophilia is often treated by replacing the missing clotting factor via intravenous infusions, also known as replacement therapy.8 About Novo Nordisk Novo Nordisk is a leading global healthcare company that's been making innovative medicines to help people with diabetes lead longer, healthier lives for more than 100 years.
