We are a clinical-stage biopharmaceutical company focused on developing therapies for patients with hypertrophic cardiomyopathy (“HCM”) and other serious cardiovascular diseases. Our lead product candidate, BHB-1893, is a next-generation oral small-molecule cardiac myosin inhibitor (“CMI”), that we are developing for the treatment of obstructive HCM (“oHCM”) and non-obstructive HCM (“nHCM”). Our goal is to improve the treatment options for these patients by enhancing speed of onset, depth of gradient response, systolic safety, and reversibility, and reducing prescribing complexity. BHB-1893 was initially discovered and developed by Jiangsu Hengrui Pharmaceuticals Co., Ltd. (“Hengrui”) in China. We in-licensed BHB-1893 pursuant to an exclusive license agreement with Hengrui, and as such, all clinical trials of BHB-1893 completed to date were designed, sponsored, and conducted by Hengrui, primarily in China, with one Phase 1 trial conducted in Australia. We were not involved in the design, conduct, or oversight of these trials. BHB-1893 has also been evaluated by Hengrui in a randomized, placebo-controlled Phase 2 trial in patients with nHCM (“Phase 2 nHCM Study 202”), from which results were presented in May 2026. Our Phase 3 development strategy is informed by clinical data generated to date, including extensive experience from prior studies conducted by Hengrui.
