Key Safety Information
- •Always follow the dose recommended by your healthcare professional. Taking more than prescribed increases the risk of side effects including serious complications.

Adult Dosage
2 DOSAGE AND ADMINISTRATION Administer Alhemo by subcutaneous injection to the abdomen or thigh with daily rotation of injection sites. ( 2.2 ) Recommended dosing regimen: • Day 1: Loading dose of 1 mg/kg • Day 2: Once daily dose of 0.2 mg/kg until individualization of maintenance dose ( 2.1 ) o 4 weeks after initiation of treatment: For dose optimization, measure concizumab‑mtci plasma concentration by Concizumab Enzyme-Linked Immunosorbent Assay (ELISA) prior to administration of next scheduled dose using an FDA-authorized test for the measurement of concizumab-mtci concentration in plasma. See full Prescribing Information for important preparation and administration instructions and dosage adjustment. ( 2.1 , 2.3 , 2.4 ) 2.1 Recommended Dosage For subcutaneous use only. Alhemo should be administered once daily. Avoid missed doses. Recommended dosing regimen: • Day 1: Loading dose of 1 mg/kg • Day 2: Once daily dose of 0.2 mg/kg until individualization of maintenance dose (see below)

- 6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: • Thromboembolic Events [see Warnings and Precautions ( 5.1 )] • Hypersensitivity Reactions [see Warnings and Precautions ( 5.2 )] • Increased Laboratory Values of Fibrin D-dimer and Prothrombin Fragment 1.2 [see Warnings and Precautions ( 5.3 )] The most frequently reported adverse reactions (incidence ≥5%) were injection site reactions, headache and urticaria.

- at 1-800-727-6500 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
- 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in clinical practice.
- The data in the WARNINGS AND PRECAUTIONS reflect exposure to Alhemo based on pooled data from clinical trials explorer3 (phase 1b), explorer4 (phase 2), explorer5 (phase 2), explorer7 (phase 3) and explorer8 (phase 3), in which a total of 320 male patients with hemophilia A with and without inhibitors and hemophilia B with and without inhibitors received at least one dose of Alhemo as routine prophylaxis.
- The patients were exposed for a total of 475 exposure years.
- Patients with HAwI (hemophilia A with inhibitors) and HBwI (hemophilia B with inhibitors) The data described below reflect exposure of 52 patients with HAwI and HBwI who were previously treated on-demand therapy and who were randomized in explorer7 to arm 1 to receive on- demand treatment with bypassing agents (n = 19) or arm 2 to receive Alhemo prophylaxis (n = 33) at the recommended dosing regimen [see Clinical Studies ( 14.1 )] .

How Alhemo Works
12.1 Mechanism of Action Concizumab-mtci is a monoclonal antibody antagonist of endogenous Tissue Factor Pathway Inhibitor (TFPI). Through the inhibition of TFPI, concizumab-mtci acts to enhance FXa production during the initiation phase of coagulation which leads to improved thrombin generation and clot formation with the goal of achieving hemostasis in patients with Hemophilia A or B regardless of their inhibitor status. The effect of concizumab-mtci is not influenced by the presence of inhibitory antibodies to FVIII or FIX. There is no structural relationship or sequence homology between concizumab-mtci and FVIII or FIX and, as such, treatment with concizumab-mtci does not induce or enhance the development of direct inhibitors to FVIII or FIX.
Pharmacokinetics
Absorption
Absorption Concizumab-mtci time to maximum plasma concentration ranged from 8 hours to 99 hours (4
Metabolism
Metabolism Concizumab-mtci is expected to be metabolized into small peptides by catabolic pathways
