Orbital Therapeutics

Orbital Therapeutics was a Cambridge, Massachusetts biotechnology company developing next-generation RNA medicines, combining circular and linear RNA, targeted delivery, and AI-guided design across immunomodulation, in vivo CAR-T cell therapy, next-generation vaccines, and protein therapeutics. Its lead program, OTX-201, targeted autoimmune disease through B-cell depletion. Founded out of Beam Therapeutics and backed by ARCH Venture Partners, a16z Bio + Health, and Newpath Partners, the company raised a $270M Series A in 2023. In October 2025 Bristol Myers Squibb agreed to acquire Orbital Therapeutics for $1.5 billion; orbitaltx.com now redirects to bms.com. As a therapeutics developer, Orbital publishes no public developer platform, API, or machine-readable API surface, so this record is an identity-only profile in the API Evangelist network.

Orbital Therapeutics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, RNA Medicines, and Cell Therapy.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
