A Study to Evaluate the Effect of Food on the Oral Bioavailability of Relacorilant in Healthy Subjects

Enrolled healthy male and female subjects will be randomized to receive 1 of 6 treatment sequences, each consisting of 3 treatments in 3 periods, in a crossover design. The 3 treatments will be a single oral dose of relacorilant 400 mg 1) under fasted conditions, 2) after a high-fat meal, and 3) after a low-fat meal. Each period will last 5 days, and a 7-day washout will follow Periods 1 and 2. Blood samples will be collected predose and at serial timepoints up to 4 days (Day 5) after dosing in each period for evaluation of the bioavailability of relacorilant. Secondary objectives of the study will be evaluation of the bioavailability of relacorilant metabolites, and evaluation of safety and tolerability of relacorilant when administered to healthy subjects under fasted and fed conditions.

Inclusion criteria

• Body mass index >18.5 and <30.0 kg/m^2 and body weight ≥50.0 kg for male subjects and ≥45.0 kg for female subjects
• Healthy, as defined by the absence of clinically significant illness and/or surgery within 4 weeks prior to dosing, and the absence of clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal, renal, hepatic, and metabolic disease
• Female subjects of childbearing potential who are sexually active with a non-sterile male partner must be willing to use an acceptable contraceptive method as defined in the protocol, throughout the study.
• Male subjects who are not vasectomized for at least 6 months, and who are sexually active with a female partner of childbearing potential must be willing to use an acceptable contraceptive method as defined in the protocol, from the first study drug administration until at least 90 days after the last study drug administration
• Male subjects must be willing not to donate sperm until 90 days following the last study drug administration.
• Capable of, and have given, written informed consent
• Willing to consume a high-fat breakfast, including pork
• Able to and willing to fast for any laboratory evaluations.

Exclusion criteria

• Any clinically significant abnormality at physical examination, clinically significant abnormal laboratory test results or positive test for HIV, hepatitis B, or hepatitis C
• Female subject with a positive pregnancy test at Screening
• Male subject with a pregnant partner at Screening
• Positive urine drug screen or urine cotinine test or alcohol breath test at Screening
• History of allergic reactions to relacorilant or other related drugs, or to any excipient in the formulation
• Clinically significant electrocardiogram abnormalities or vital sign abnormalities at Screening
• History of significant alcohol abuse within 1 year prior to screening or regular use of alcohol within 6 months prior to the screening visit (more than 14 units of alcohol per week [1 unit = 83 mL of wine 12%, 200 mL of beer 5%, or 25 mL of alcohol 40%])
• History of significant drug abuse within 1 year prior to Screening or use of soft drugs within 3 months prior to Screening or hard drugs within 1 year of Screening
• Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to the first dosing, administration of a biological product in the context of a clinical research study within 90 days prior to the first dosing, or concomitant participation in an investigational study involving no drug or device administration
• Use of medications for the timeframes specified in the protocol, with the exception of acceptable hormonal contraceptives and medications exempted by the Investigator, with agreement by the Sponsor because they are judged unlikely to affect the pharmacokinetic profile of the study drug or subject safety
• Donation of plasma within 7 days prior to dosing. Donation or loss of blood (excluding volume drawn at screening) of 50 mL to 499 mL of blood within 30 days, or more than 499 mL within 56 days prior to the first dosing
• Have a condition that may be aggravated by glucocorticoid antagonism (eg, asthma, any chronic inflammatory condition). Subjects with inactive seasonal hay fever may be included. Subjects with childhood (aged less than 18 years) asthma may be included provided they have had no symptoms and required no treatment for at least 5 years.
• History of malabsorption syndrome or previous gastrointestinal surgery, which could affect drug absorption or metabolism, with the exception of appendectomy and cholecystectomy
• Pregnant or breast-feeding
• Any reason which, in the opinion of the Investigator, would prevent the subject from participating in the study.
