Kronos Bio to Present Preclinical Data for KB-0742, an Oral CDK9 Inhibitor Targeting MYC-amplified Cancers, in Pediatric Cancer Models in Poster Presentation at EORTC-NCI-AACR 2022
Company Plans to Provide Update and Recommended Phase 2 Dose from Ongoing KB-0742 Phase 1/2 Clinical Trial in Q4 2022
SAN MATEO, Calif. and CAMBRIDGE, Mass., Oct. 12, 2022 (GLOBE NEWSWIRE) — Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer, today announced that it will present preclinical data in a poster at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, Spain. The meeting will be held from Oct. 26-28, 2022.
The poster will include preclinical data demonstrating that Kronos Bio’s internally discovered oral CDK9 inhibitor, KB-0742 induced regressions in a preclinical model of MYCN-amplified neuroblastoma tumors and inhibited growth in patient-derived xenograft (PDX) models of transcriptionally addicted Ewing sarcoma (EW) and alveolar rhabdomyosarcoma (ARMS).
This is the first preclinical analysis to support the investigational compound’s potential in pediatric tumors. KB-0742 is being developed for the treatment of MYC-amplified and transcriptionally addicted solid tumors and is currently being assessed as part of an ongoing Phase 1/2 study. Kronos Bio remains on track to provide an update on the study, including the Recommended Phase 2 Dose (RP2D) in the fourth quarter.
The abstract is now available on the conference website. Details of the poster presentation are as follows:
Poster Title: Regulation of oncogenic transcription and tumor growth in pediatric cancers by the CDK9 inhibitor KB-0742
Abstract Number: PB088
Date and Time: Oct. 27, 10 a.m. Central European Time
KB-0742 is a highly selective, orally bioavailable inhibitor of cyclin dependent kinase 9 (CDK9) in development for the treatment of MYC-amplified solid tumors. CDK9 is a global regulator of transcription and plays an essential role in both the expression and function of MYC, a well-characterized transcription factor and a long-recognized driver of cancer that is amplified in approximately 30% of solid tumors, including those affecting the lungs, ovaries and breast. KB-0742 was generated and optimized from a compound that was identified using the company’s proprietary small molecule microarray (SMM) screening platform.
