• Kronos Bio Continues to Advance Investigational SYK Inhibitors Entospletinib and Lanraplenib with New Preclinical Data at EHA2022 Congress

    SAN MATEO, Calif. and CAMBRIDGE, Mass., June 10, 2022 (GLOBE NEWSWIRE) -- Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer and other serious diseases, will present preclinical data today from studies of the company’s two novel investigational spleen tyrosine kinase (SYK) inhibitors, entospletinib and lanraplenib. The poster presentations will take place at the European Hematology Association (EHA) 2022 Congress in Vienna.

    The company is enrolling patients in clinical trials studying each compound and the preclinical data provide additional support for the biological rationale for the targeting of SYK in patients with genetically defined subsets of acute myeloid leukemia (AML).

    The registrational Phase 3 AGILITY trial is assessing entospletinib in combination with standard of care cytarabine and anthracycline (7+3) chemotherapy in patients with NPM1-mutated AML, with data anticipated in the second half of 2023. The AGILITY trial is the first in AML to use measurable residual disease as a primary endpoint, a novel trial design that has the potential to accelerate the development of entospletinib.

    Lanraplenib is being assessed as a potential treatment for patients with relapsed/refractory AML in combination with gilteritinib in a Phase 1b/2 study.

    “At Kronos Bio, we are focused on developing novel therapies targeting the dysregulated transcription that is a hallmark of cancer,” said Jorge DiMartino, M.D., Ph.D., chief medical officer and executive vice president, Clinical Development. “Our work in AML is focused on SYK, a critical dependency in NPM1-mutated and FLT3-mutated AML. The data that we are presenting today add to the growing evidence that this approach has the potential to offer a way to target genetically defined AML.”

    The first poster describes the analysis of mutational and gene expression signatures from bone marrow and peripheral blood samples of patients with NPM1-mutated AML, suggesting that the NPM1 mutation, with or without co-mutation of FLT3, is a strong predictor of entospletinib anti-leukemic activity. Additional experiments suggested that entospletinib and lanraplenib could restore T-cell proliferation in a subset of AML samples from patients with dysfunctional T-cell responses, suggesting a novel mechanism of action. The data provide additional support to suggest that inhibition of SYK is a promising therapeutic approach in NPM1- and FLT3-mutated AML.

    The research was conducted as part of a collaboration with scientists at the Oregon Health & Science University.

    The second poster describes the company’s findings of synergistic activity of lanraplenib in combination with other targeted agents, including gilteritinib, in an NPM1-mutated/FLT3-mutated PDX model. These findings provide additional support for ongoing and future clinical studies.

    Two additional posters detail the design of the entospletinib and lanraplenib clinical studies.
