Company Overview

About Orbital Therapeutics

Orbital Therapeutics is a clinical-stage biotechnology company founded in 2022 and headquartered in Cambridge, Massachusetts, with a mission to unlock the full potential of RNA medicines. The company operates at the frontier of RNA biology, advancing a platform that spans circular RNA, self-amplifying RNA, and in vivo CAR-T cell therapies — technologies designed to go beyond the mRNA approaches pioneered during the COVID-19 era. Orbital was co-founded by leading RNA scientists and backed by ARCH Venture Partners, a16z Bio + Health, Newpath Partners, the Abu Dhabi Growth Fund, and Redmile Group, among others.

Business Model & Competitive Advantage

In April 2023, Orbital closed a $270 million Series A financing round to fuel discovery and IND-enabling programs across autoimmune disease, oncology, and inflammatory conditions. By mid-2025, the company publicly disclosed its lead program, OTX-201, an in vivo CAR-T therapy targeting B-cell-mediated autoimmune diseases. Non-human primate data presented at a major conference demonstrated complete B-cell depletion in blood, spleen, and lymph nodes — a requirement for effective immune system reset — setting the stage for a first-in-human clinical trial planned for the first half of 2026.

Competitive Landscape 2025–2026

In 2025, Bristol Myers Squibb announced an agreement to acquire Orbital Therapeutics for approximately $1.5 billion, drawn to the company's in vivo cell therapy approach and its potential to rewire immune systems in people with inflammatory conditions. The acquisition reflects growing Big Pharma conviction in next-generation RNA platforms as an alternative to ex vivo cell therapy, which requires removing, engineering, and re-infusing a patient's own cells. If completed, the deal would make Orbital's circular RNA and in vivo CAR-T technologies part of Bristol Myers Squibb's cell therapy portfolio.
