Innovent Biologics Inc., in collaboration with Sanegene Bio USA Inc., has announced preliminary results from a first-in-human Phase 1 clinical study of IBI3016 (also known as SGB-3908), an experimental small interfering RNA (siRNA) medicine targeting angiotensinogen mRNA $(AGT)$ for the treatment of hypertension. The results were presented at the 2025 American Heart Association (AHA) scientific sessions. According to the companies, IBI3016 demonstrated sustained and potent AGT mRNA suppression with preliminary evidence of antihypertensive efficacy following a single-dose subcutaneous administration. The Phase 1 data suggest the potential for biannual subcutaneous dosing for hypertension treatment. The companies plan to initiate the next phase of clinical development soon.
