A Study of HC-5404-FU to Establish the Maximum Tolerated Dose (MTD)

HC 5404-FU (hemi fumarate salt of HC 5404) is a novel, highly selective, and potent PERK inhibitor. Preclinical pharmacological studies demonstrated high specificity of HC 5404-FU to PERK and decreased viability of tumor cells. HC 5404-FU will be orally administered BID every day with food or within 30 minutes of completing a meal, starting at 25 mg, with doses escalating to 50, 100, 200, 400, 600, and 900 mg BID as safety allows for each 3-week treatment cycle.
