Drug intelligence / Profile preview
OJI-220 is a wood-derived anticoagulant being developed by Oji Pharma, a subsidiary of Oji Holdings, for the prevention of blood coagulation during extracorporeal circulation in hemodialysis. Derived from forest resources, OJI-220 is intended as a sustainable and culturally inclusive alternative to traditional porcine-derived heparin, addressing supply chain vulnerabilities and religious or cultural restrictions associated with animal-derived products. In March 2026, Oji Pharma submitted a clinical trial plan notification to the Japanese Pharmaceuticals and Medical Devices Agency (PMDA) to initiate a Phase I first-in-human study. This trial aims to evaluate the safety, tolerability, and pharmacokinetics of OJI-220 in healthy adult males.
