Orna Therapeutics is a biotechnology company pioneering a new class of fully engineered circular RNA (oRNA) therapies. Founded in 2019 based on groundbreaking research from MIT, Orna's proprietary technology creates circular RNAs from linear RNAs through self-circularization. This circular shape offers several advantages over traditional linear mRNA, including simplified production, increased protein expression, and greater stability in vivo. Orna's oRNA molecules are packaged into custom lipid nanoparticles (LNPs) engineered to target specific tissues in the body.
The company's lead program, ORN-101, is a development-stage in situ CAR therapy designed to modify a patient's immune cells inside their body. preclinical data demonstrated tumor suppression and eradication in animal models at doses 10-20 fold lower than previously reported. In May 2023, Orna presented data showing ORN-101's tumor eradication ability after 2-3 doses in a mouse model. The company is advancing ORN-101 as a potential off-the-shelf, redosable immunotherapy that could overcome barriers of existing autologous CAR-T therapies.
In May 2024, Orna acquired ReNAgade Therapeutics, a company specializing in RNA delivery technologies. This acquisition unified Orna's circular RNA platform with ReNAgade's RNA delivery systems to advance an industry-leading approach combining circular RNA expression technology with LNP-based delivery. The combined company aims to develop panCAR in vivo CAR RNA therapies for oncology and autoimmune diseases, as well as expand gene editing delivery solutions using circular RNA.
