This is an open label, single sequence, crossover study. In Part 1, eligible subjects will participate in 3 treatment periods, in which they will receive the following treatments in turn: 1) In Period 1, a single 350-mg dose of relacorilant administered alone, 2) In Period 2, once daily 200-mg doses of itraconazole administered for 3 days; 3) In Period 3, single 350-mg dose of relacorilant administered with a concomitant 200-mg dose of itraconazole and continued once daily 200-mg doses of itraconazole for three additional days. If Part 2 is conducted, eligible subjects will participate in 2 treatment periods, in which they will receive the following treatments in turn: 1) In Period A, once daily 300-mg doses of relacorilant alone for 10 days; 2) In Period B, once daily 300-mg doses of relacorilant in combination with once daily 200-mg doses of itraconazole for 10 days.
