Lanraplenib trial to start in Q1 2022; Phase 3 registrational AGILITY trial of entospletinib underway, with results anticipated in the second half of 2023
$339.5 million in cash, cash equivalents and investments as of December 31, 2021, providing expected runway into the second half of 2024
SAN MATEO, Calif. and CAMBRIDGE, Mass., Feb. 24, 2022 (GLOBE NEWSWIRE) -- Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer and other serious diseases, today reported recent business progress and fourth-quarter and full-year 2021 financial results.
“We had a successful year, marked by the significant progress we made across our clinical pipeline, including initiating our registrational Phase 3 AGILITY study of entospletinib, and initiating our Phase 1/2 study of KB-0742 and subsequently reporting positive initial results from the KB-0742 study,” said Norbert Bischofberger, Ph.D., president and chief executive officer of Kronos Bio. “We expect to announce the initiation of our third clinical trial later this quarter. We continue to dose-escalate KB-0742 and anticipate reaching the recommended Phase 2 dose and sharing additional Phase 1 data in the fourth quarter.”
Kronos Bio is continuing to enroll patients in the Phase 1/2 trial of KB-0742. KB-0742 is the company’s internally discovered, highly selective, orally administered cyclin dependent kinase 9 (CDK9) inhibitor being developed to treat MYC-amplified and other transcriptionally addicted solid tumors. Kronos Bio reported positive initial data from the study last year and is continuing to dose escalate.
The company expects to announce a recommended Phase 2 dose and announce updated Phase 1 data in Q4 2022.
While the first stage of the study does not mandate enrollment of patients with MYC amplification or other evidence of transcriptional addiction, as the trial nears pharmacologically active dose levels, the company anticipates increased enrollment of patients who may be more likely to respond to CDK9 inhibition.
SYK Inhibitor Program Update
Kronos Bio expects to dose the first patient in a Phase 1b/2 clinical trial of lanraplenib in the first quarter of 2022. This trial will evaluate lanraplenib in patients with relapsed or refractory FLT3-mutated acute myeloid leukemia (AML) in combination with the current standard of care, gilteritinib.
To better focus on and prioritize the company’s resources on the areas of highest unmet need, Kronos Bio has decided not to proceed at this time with its previously planned second Phase 1b/2 clinical trial of lanraplenib in combination with venetoclax/azacitidine.
Fourth-Quarter Company Highlights
Kronos Bio dosed the first patient in the registrational Phase 3 AGILITY clinical trial of entospletinib, a selective inhibitor targeting spleen tyrosine kinase (SYK), in combination with standard of care anthracycline and cytarabine (7+3) chemotherapy. This trial is the first in AML to use measurable residual disease (MRD) as the primary endpoint and has the potential to support accelerated approval of entospletinib by the U.S. Food and Drug Administration as a treatment for patients newly diagnosed with NPM1-mutated AML who are fit for intensive induction. The company expects to share data from the trial in the second half of 2023.
Kronos Bio announced positive data from the ongoing Phase 1/2 clinical trial of KB-0742. The initial analysis of the ongoing dose escalation stage of the trial demonstrated a differentiated pharmacokinetic profile and evidence of target engagement for KB-0742.
Kronos Bio appointed Roshawn Blunt to its Board of Directors. Ms. Blunt has decades of experience in the commercialization of new therapeutics, including oncology medicines, with expertise in patient access, reimbursement and health policy. Her expertise will be highly relevant as Kronos Bio advances its lead programs.
Kronos Bio announced its multi-year collaboration with Tempus Labs, Inc., a leader in artificial intelligence and precision medicine, during the fourth quarter. The agreement provides Kronos Bio with access to real-world patient genomic and transcriptomic data and data analytics tools, with the goal of accelerating the development of the company’s current and future clinical portfolio.

Forward-looking statements include statements regarding Kronos Bio’s intentions, beliefs, projections, outlook, analyses or current expectations concerning, among other things: Kronos Bio’s plans to begin a Phase 1b/2 clinical trial of lanraplenib in the first quarter of 2022 and the design of such trial; anticipated increased enrollment of patients who may be more likely to respond to CDK9 inhibition in Kronos Bio’s ongoing Phase 1/2 clinical trial of KB-0742; the anticipated timing for reaching the recommended Phase 2 dose; the anticipated timing for reporting data; the potential of the registrational Phase 3 AGILITY clinical trial of entospletinib to support accelerated approval of entospletinib as a treatment for patients newly diagnosed with NPM1-mutated AML who are fit for intensive induction chemotherapy; the potential benefits to Kronos Bio from its collaboration with Tempus; the anticipated sufficiency of the company’s resources to fund its planned operations into the second half of 2024; and other statements that are not historical fact. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, including, without limitation: whether Kronos Bio will be able to initiate or complete the current and planned clinical trials of entospletinib, lanraplenib and KB-0742 on the timeline expected, if at all, including due to risks associated with the COVID-19 pandemic and risks inherent in the clinical development of novel therapeutics; risks related to using MRD negative complete response as the primary endpoint to support potential accelerated approval in patients newly diagnosed with NPM1-mutated AML who are fit for intensive induction chemotherapy, including the fact that so far there have not been any regulatory approvals on the basis of MRD status in AML; risks related to Kronos Bio’s lack of experience as a company in conducting clinical trials; the risk that results of preclinical studies and early clinical trials are not necessarily predictive of future results; and risks associated with the sufficiency of Kronos Bio’s cash resources and need for additional capital.
