Chimeron Bio is becoming Acirna Therapeutics → 

A New Chapter in RNA Medicine

Same mission. RNA REINVENTED.

Building on our foundation in self-amplifying RNA, we have developed amplified circular RNA (acRNA)-a new class of RNA technology that unites amplification and circularization in a single, more powerful platform. acRNA opens a new design space for precision RNA programming, creating new possibilities for how RNA medicines are engineered and deployed.

This advance marks the next chapter for Chimeron Bio and a new identity: ACIRNA Therapeutics.
Our mission remains the same: developing first- and best-in-class RNA therapeutics engineered to reprogram the immune system against cancer and autoimmune disease.

A name built from our science.

The name also draws inspiration from the Latin accīre- “to summon” or “to call forth”- evoking the company’s core mission: using precision mRNA programming to summon the immune system into action.
