About RGT-61159
RGT-61159 is an orally available small molecule designed to specifically modulate splicing of the transcription factor MYB resulting in the inhibition of the oncogenic MYB protein and potential cell death of the cancer cells that overexpress the MYB protein. MYB acts as a master regulator of cell proliferation, self-renewal, and differentiation processes and its aberrant expression has been demonstrated in multiple forms of human cancer including adenoid cystic carcinoma (ACC), acute myeloid leukemia (AML), T-cell acute lymphoblastic leukemia (T-ALL), colorectal cancer (CRC), small cell lung cancer (SCLC) and breast cancer. Rgenta is evaluating RGT-61159 in an ongoing multi-center, open-label Phase 1a/b clinical trial in patients with advanced relapsed or refractory ACC or CRC. The Phase 1a/b study is designed to evaluate safety, tolerability, pharmacokinetics, target engagement, and clinical efficacy of RGT-61159 in patients with ACC or CRC. Additional information about the Phase 1a/b clinical trial can be accessed at ClinicalTrials.gov (NCT06462183).
