ARD-2128 is a bona fide PROTAC androgen receptor (AR) degrader and strongly suppresses AR-regulated genes in a dose- and time-dependent manner in AR+ prostate cancer cell lines. ARD-2128 has excellent plasma and microsomal stability in all the five species (Human, Mouse, Rat, Dog, and Monkey). The in vitro stability and pharmacokinetic (PK) studies were performed by Medicilon.
