PRLD Prelude Therapeutics Inc

Prelude Therapeutics Incorporated (Nasdaq: PRLD), a clinical-stage precision oncology company, today announced that three posters with preclinical data on the Company’s highly selective oral SMARCA2 degrader, its potentially best-in-class CDK9 inhibitor and its next-generation CDK4/6 inhibitor, have been accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting 2024, taking place from April 5 to 10, 2024.

Peggy Scherle, Ph.D., Chief Scientific Officer of Prelude, stated, “We look forward to sharing data on the preclinical characterization of our lead oral SMARCA2 degrader, PRT7732, which is on track to advance into Phase 1 clinical development in the second half of this year, and to presenting additional preclinical data for our highly selective and potent CDK9 inhibitor, PRT2527, that supports its potential therapeutic value in combination with BTK and BCL2 inhibitors in lymphoid malignancies. For our next generation CDK4/6 inhibitor, PRT3645, we will present preclinical data supporting its potential therapeutic value in combination with other targeted therapies for a range of tumor types in addition to breast cancer.”

Details on the poster presentations are as follows:
