Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Parts I and 4 of the study are double-blind, randomized, placebo-controlled assessments of single-ascending doses (SAD) of CORT118335. Subjects will be enrolled sequentially into 1 of up 8 cohorts (Part 1, Cohorts A to D \[Cohorts E to G have been cancelled\]; Part 4, Cohorts A to D), each containing 8 subjects. Within each cohort, 6 subjects will be randomly assigned to receive a single dose of CORT118335 and 2 subjects will be randomly assigned to receive a single dose of matching placebo.
Part 2 Cohort A, food-effect, will be an open-label 2-way crossover study in one cohort of 12 subjects, randomized in a 1:1 ratio to receive a single dose of CORT118335 once after an overnight fast and once after a high-fat breakfast or the alternate sequence, over 2 study periods separated by a washout of at least 7 days/5 half-lives.
Part 2 Cohort B, PD cohort, will be a double-blind, randomized, placebo-controlled, 3-way cross-over study and will serve as proof of pharmacological effect (GR modulation) for CORT118335. Subjects will be randomized in a 1:1:1 ratio to receive placebo, and two dose levels of CORT118335 in one of three treatment sequences across 3 study periods separated by washouts of at least 7 days/5 half-lives. On each occasion, the ability of CORT118335 to ameliorate the pharmacological effects of a single dose of prednisone will be measured.
Parts 3 and 5 are double-blind, randomized, placebo-controlled assessments of multiple oral ascending doses of CORT118335. Subjects will be enrolled sequentially into 1 of up to 4 cohorts (Part 1 Cohort A \[Cohorts B to D have been cancelled; Part 5 Cohorts A to C), each containing 12 subjects. Within each cohort, 9 subjects will be randomly assigned to receive CORT118335 and 3 subjects to receive matching placebo daily for 14 days.
Different formulations of CORT118335 will be used in Parts 1, 2 and 3, and in Parts 4 and 5.
