mRNA degrader REM-422

REM-422 is a first-in-class orally available, small molecule mRNA degrader that targets the pre-mRNA of MYB, a previously undruggable transcription factor known to drive a diverse range of diseases.

Active Trials

REM-422 is currently in Phase 1 clinical studies in both ACC and AML or high-risk myelodysplastic syndrome (HR-MDS). REM-422 may also have therapeutic potential beyond ACC and AML. MYB has been implicated in tumorigenesis across a wide variety of hematological malignancies and solid tumors including breast cancers, colon cancers, and lymphomas, among others.

Orchestrating New Possibilities in MYB-driven Cancers

Preclinical data with REM-422 demonstrates the importance of addressing the MYB protein as the driver of diseases like adenoid cystic carcinoma (ACC), a cancer of secretory glands, typically originating in the head and neck region, and acute myeloid leukemia (AML). REM-422 has been shown to exhibit anti-tumor activity across a variety of preclinical models in both ACC and AML. Preliminary positive results from the Phase 1 trial of REM-422 in ACC has demonstrated inhibition of MYB mRNA and anti-tumor activity at well-tolerated doses. REM-422 was granted Orphan Drug Designation by the FDA for ACC and AML.
REM-422 acts by promoting myb poison exon inclusion to induce mRNA degradation.
