Chroma Medicine

Chroma Medicine was a Boston-based, clinical-stage biotechnology company developing epigenetic editors — CRISPR-derived medicines that silence or activate genes by writing epigenetic marks rather than cutting DNA — with CRMA-1001, a liver-targeted epigenetic editing therapy for chronic hepatitis B and hepatitis D, as its lead program. In December 2024 it merged with Nvelop Therapeutics, pairing Chroma's epigenetic editors with Nvelop's non-viral in vivo delivery vehicles, to form nChroma Bio with $75 million in new financing. chromamedicine.com now redirects to nchromabio.com. As a therapeutics developer it publishes no developer program, public API, SDK, or machine-readable specification of any kind.

Chroma Medicine is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Genetic Medicine, and Epigenetic Editing.

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/.
