“These positive preliminary efficacy and safety data underscore the promise of KB-0742 to treat patients with transcriptionally addicted tumors. The observed anti-tumor activity and absence of grade 3/4 neutropenia are particularly encouraging as we continue to enroll patients and explore a maximum tolerated dose,” said Jorge DiMartino, M.D., Ph.D., Chief Medical Officer and Executive Vice President, Clinical Development. “We look forward to advancing the study and reporting additional results, including data from the dose expansion portion of the study, mid next year.”
