Krakow, Poland – 04 November 2021 – Ryvu Therapeutics [WSE:RVU], a clinical-stage drug discovery and development company focusing on novel small molecule therapies that address emerging targets in oncology, announced today that it will present new data demonstrating clinical and preclinical activity of its selective CDK8/19 inhibitor RVU120 (SEL120) and its selective PIM/FLT3 inhibitor SEL24 (MEN1703) during the 63rd American Society of Hematology Annual Meeting & Exposition, being held on December 11 – December 14, 2021, in Atlanta and at the 44th Annual San Antonio Breast Cancer Symposium (SABCS) being held on December 7 – December 10, 2021.
An acceptable safety profile and early signs of efficacy will be presented for RVU120, a selective CDK8/19 inhibitor being developed in hematologic and solid tumors, in the first-in-human (FIH) Phase Ib dose-escalation trial (CLI120-001) currently ongoing in patients with relapsed/refractory (R/R) acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (HR-MDS). The preliminary signs of efficacy for RVU120 include a Complete Response (CR) in an AML patient and an erythroid response (ER) in an HR-MDS patient who had relapsed after several lines of previous treatment.
Translational research will be presented that potentially links the clinical response in an AML patient to DNMT3A-mutations via evidence in DNMT3A-mutated AML patient-derived cells (PDCs). Further translational research shows evidence that the clinical erythroid response in an MDS patient is potentially a result of strong erythroid differentiation potential of RVU120 in preclinical models. Enrollment is ongoing in cohort 4 at seven clinical sites in the US and Europe to gather additional safety data in the study.
An additional poster on the potential efficacy of RVU120 in hormone-negative breast cancer models will be presented at the 2021 San Antonio Breast Cancer Symposium®.
Ryvu licensee Menarini Group will be presenting SEL24/MEN1703 data from the First-in-Human, Dose Escalation (DE) and Cohort Expansion (CE) CLI24-001 trial (DIAMOND-01, ClinicalTrials.gov identifier: NCT03008187).
“We are excited to present data from our ongoing Phase Ib dose escalation study of RVU120 in AML and HR-MDS, where we have seen clinical responses, and in solid tumors with strong translational data in breast cancer,” said Pawel Przewiezlikowski, Chief Executive Officer at Ryvu Therapeutics. “It is a true milestone for Ryvu and our collaborators from MD Anderson Cancer Center and Menarini to have six posters accepted for presentation on RVU120 and SEL24.”
