WILMINGTON, Del., April 11, 2023 (GLOBE NEWSWIRE) -- Prelude Therapeutics Incorporated (Nasdaq: PRLD), a clinical-stage precision oncology company, today announced details relating to eight abstracts being presented at the American Association for Cancer Research (AACR) Annual Meeting 2023, taking place April 14-19 in Orlando, Florida. “Prelude's six preclinical and two clinical abstracts being presented at the AACR Annual Meeting highlight the important progress we are making across our pipeline. Initial safety, pharmacokinetic and pharmacodynamic profiles in solid tumors for both PRT2527 and PRT1419 support continued development of both compounds in hematological cancers,” said Jane Huang, M.D., President and Chief Medical Officer of Prelude. “Additionally, we will be presenting preclinical data on our orally bioavailable SMARCA2 degrader program for the first time.” “We are also presenting preclinical data for both our next generation CDK4/6 inhibitor CDK4/6 inhibitor, PRT3645, and our SMARCA2 degrader, PRT3789, in combination with other targeted therapies. These studies demonstrate the favorable combinability of our compounds with standard of care medicines and inform potential clinical development,” added Peggy Scherle, Ph.D., Chief Scientific Officer of Prelude. Details of the clinical abstracts upcoming presentations are as follows: Title: A phase 1, open-label, dose-escalation study of PRT1419, a selective induced myeloid leukemia cell differentiation protein (MCL-1) inhibitor differentiation protein (MCL-1) inhibitor, in patients (pts) with advanced/metastatic solid tumors Presenter: Gerald Falchook Session Title: First-in-Human Phase I Clinical Trials 2 Date and Time: Tuesday April 18, 2023, 9:00 AM - 12:30 PM Location: Poster Section 45 Poster Board Number: 4 Abstract Presentation Number: CT172 Title: A phase 1, open-label, multicenter, dose-escalation study of PRT2527, a cyclin-dependent kinase 9 (CDK9) inhibitor cyclin-dependent kinase 9 (CDK9) inhibitor, in adult patients (pts) with advanced solid tumors Presenter: Jason T.
