Remix Therapeutics is a Massachusetts biotech that makes small molecules to change how RNA is processed; REM-422 destroys the messenger RNA for the transcription factor MYB, a driver of adenoid cystic carcinoma and acute myeloid leukaemia.
Remix Therapeutics uses its REMaster platform to design small molecules that reprogramme RNA splicing and stability. REM-422 induces a poison exon in MYB mRNA, marking it for degradation and lowering MYB protein; it is in phase 1 trials in adenoid cystic carcinoma and in acute myeloid leukaemia and higher-risk myelodysplastic syndromes. The company has partnerships with Janssen and Roche on other RNA-processing targets.
REM-422 is a small-molecule inhibitor from Remix Therapeutics, in registered phase 2 trials for salivary gland cancers.
