SEL24 (MEN1703) Clinical Data from DIAMOND-01 Trial to be Presented at ASCO and EHA Virtual Meetings 2021

SEL24 (MEN1703), a first in class, orally available, dual PIM/FLT3 inhibitor, discovered and initially developed by Ryvu Therapeutics, then licensed out to – and currently developed by – the Menarini Group, is being evaluated in the DIAMOND-01 trial for the treatment of Acute Myeloid Leukemia

Krakow, Poland – June 01, 2021 – Ryvu Therapeutics (WSE: RVU) today announced that the latest results from the DIAMOND-01 clinical trial (CLI24-001; identifier NCT03008187) will be disclosed through poster presentations at both the upcoming American Society of Clinical Oncology (ASCO) and European Hematology Association (EHA) Virtual Congresses, to be held on June 4-8, and June 9-17, respectively.

DIAMOND-01 is a First-in-Human, Phase I/II, dose escalation and cohort expansion trial of SEL24 (MEN1703), a first in class, orally available, dual PIM/FLT3 inhibitor in-licensed by Menarini Group from Ryvu Therapeutics, which is currently investigated as single agent for the treatment of patients with Acute Myeloid Leukemia (AML).

In the dose escalation part of DIAMOND-01 trial, SEL24(MEN1703) demonstrated a manageable safety profile up to the recommended dose (RD) of 125 mg/day, along with initial evidence of anti-leukemic activity in a single agent setting.

Data reported in the ASCO and EHA posters refers to the patients enrolled in the Phase II, cohort expansion part of the study, which confirmed the manageable safety profile of the drug at the RD and showed preliminary single agent efficacy in relapsed/refractory AML, particularly in patients with IDH mutant disease either naïve or previously exposed to IDH inhibitors. These results warrant further investigation of SEL24 (MEN1703) in AML, with a potential to focus on the IDH mutated subset.

“We are thrilled to share encouraging results for SEL24 (MEN1703) in treating patients with Acute Myeloid Leukemia,” said Dirk Laurent, M.D., Global Therapeutic Area Head – Oncology at Menarini Ricerche, the R&D division of the Menarini Group. “The data, which will be presented in our posters at both ASCO and EHA annual meetings, provides a strong rationale for further clinical development, including the potential to focus on a molecularly defined subset of patients. This accomplishment reflects our sustained commitment to improving the lives of patients with difficult-to-treat cancer and underscores the value of our precision oncology approach.”

“We are very happy to see that SEL24 (MEN1703), developed in collaboration with Menarini, continues to build momentum in the clinic demonstrating promising single agent efficacy in a genetically well-defined patient population after earlier encouraging safety and efficacy data in all-comer AML setting” – said Setareh Shamsili, MD, PhD, Chief Medical Officer of Ryvu Therapeutics.
