After a year, 79% of patients on an experimental heart drug had readings below an obstruction threshold.
Braveheart Bio (BRVE) and Hengrui Pharma (SSE: 600276, HKEX: 1276) presented 52-week data on HRS/BHB-1893, showing improved exercise capacity and patient outcomes in oHCM patients. The drug demonstrated rapid, durable LVOT gradient reduction and potential diastolic function improvements. Braveheart Bio will host an investor event to discuss the data and future plans, including a planned Phase 2b study.
