We are a clinical-stage biotechnology company developing therapies that reimagine the treatment of blood coagulation disorders to sustain life and human resilience. Our mission is to build the leading coagulation company by discovering, developing, and commercializing innovative therapies for the millions of patients worldwide suffering from serious bleeding and thrombotic diseases. Coagulation disorders encompass a broad and heterogeneous group of conditions, and many patients experience significant life-long disease burden due to either a lack of available prophylactic therapies or limitations associated with existing treatment approaches. Our lead asset, sutacimig (HMB-001), is a bispecific antibody currently in Phase 1/2 clinical development for the prophylactic treatment of Glanzmann thrombasthenia and Phase 2 clinical development for the prophylactic treatment of Factor VII deficiency. Our second clinical-stage asset, HMB-002, is a monovalent antibody in Phase 1/2 clinical development for the subcutaneous prophylactic treatment of Von Willebrand Disease. We are also advancing multiple preclinical and discovery-stage assets. We estimate that there are approximately an aggregate of 10,000 patients with Glanzmann thrombasthenia and Factor VII deficiency and an aggregate of 120,000 patients with Von Willebrand Disease in the geographies where we intend to commercialize our assets, including the United States, the European Union, Japan, the Gulf Cooperation Council countries and other select regions. With greater disease burden awareness, potential regulatory approvals of new prophylactic options and expanding global reach of these options, we believe the overall number of addressable patients for our clinical-stage assets, and preclinical and discovery stage programs could be greater than we currently estimate. We aim to establish the industry’s leading coagulation franchise through the execution of our “Hemab 2x3 by 2030” strategic roadmap, which is designed to build a franchise consisting of 2 commercial medicines, 2 new late-stage clinical programs, and 2 new early-stage clinical programs by 2030. We have not yet initiated pivotal trials for any of our product candidates, and due to the novel and unproven nature of our programs, their current stage of development and the lack of approved prophylactic therapies to inform endpoint selection and trial design, we may not be able to achieve our strategic goals on the timeline we expect or at all. Our principal executive offices are located in Cambridge, MA.
