Orbital is a privately held biotechnology company focused on reprogramming the immune system in vivo to treat diseases, with a particular focus on autoimmune conditions.
The centerpiece of the acquisition is OTX-201, Orbital’s lead preclinical candidate currently in IND-enabling studies. OTX-201 is an investigational next-generation CAR T-cell therapy that uses an optimized circular RNA encoding a CD19-targeted CAR, delivered via targeted lipid nanoparticles (LNPs), for in vivo expression. This innovative in vivo approach allows the patient's own body to manufacture the CAR T-cells, potentially offering a reduced treatment burden and improved accessibility compared to the complex ex vivo CAR T-cell therapies currently available.
BMS’s Chief Research Officer, Dr. Robert Plenge, noted that this approach could redefine the treatment of autoimmune diseases by depleting autoreactive B cells and resetting the immune system. The deal also includes Orbital’s proprietary RNA platform, which integrates circular and linear RNA engineering, advanced LNP delivery, and AI-driven design, enabling the creation of durable, programmable RNA therapies for a broad spectrum of diseases beyond autoimmune indications. BMS, already a leader with two approved CAR T-cell therapies, views the acquisition of Orbital’s platform as a critical step in making CAR T-cell therapy more efficient and accessible to more patients globally.
