Description: ATR-101, also known as PD-132301 (a free base) or PD-132301-2 (a HCl salt), is in clinical development for the treatment of adrenocortical carcinoma (ACC). ATR-101 is a selective inhibitor of ACAT1 (acyl coenzyme A:cholesterol acyltransferase). ACAT1 catalyzes cholesterol ester formation and, in the adrenals, is particularly important in creating a reservoir of substrate for steroid biosynthesis. ATR-101 is uniquely distributed to adrenal tissues and inhibition of adrenal ACAT1 by ATR-101 disrupts steroidogenesis and leads to selective apoptosis of steroid producing adrenocortical-derived cells. Similar effects have been seen in the human ACC cell line, H295R. ATR-101 has shown pre-clinical efficacy in H295R xenograft mouse models. ACC is an ultra-rare malignancy, occurring in about 2 per million population annually.
