Prelude Therapeutics Incorporated (Nasdaq: PRLD), a precision oncology company, today announced that a poster with preclinical data on the Company's oral KAT6A selective degrader (PRT13722) has been accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting 2026, taking place from April 17-22.

KAT6 is an emerging and recently validated target in the treatment of ER+ breast cancer. Prelude discovered and is developing first-in-class, highly potent, highly selective and orally bioavailable KAT6A selective degraders. The Company has selected a development candidate and remains on track to file an IND in mid-2026 with phase 1 study initiation planned in the 2nd half of 2026. Prelude believes that selectively degrading KAT6A has the potential for improved efficacy, tolerability and combinability with other agents relative to non-selective inhibitors of KAT6A/B and KAT7.
