Healthy Clinical Trial
Official title:
A Phase 1, Randomized, Open-label, Crossover Study to Determine the Relative Bioavailability of Relacorilant Administered as 3×100-mg Softgel Capsules, 3×100 mg Hard Shell Capsules, and 6×50-mg Hard-shell Capsules in Healthy Adult Subjects

This is an open-label, randomized, 3 treatment, 3-period, 6-sequence, crossover study
conducted at a single study center to characterize the relative bioavailability of
relacorilant administered as 3×100-mg softgel capsules (Treatment A), 3×100 mg hard-shell
capsules (Treatment B), and 6×50-mg hard shell capsules (Treatment C/reference) in healthy,
fasted, adult subjects.
Eligible subjects will participate in 3 treatment periods. During each treatment period,
subjects will receive a single 300-mg relacorilant dose. An equal number of subjects will be
randomized to each of 6 sequences.

Inclusion Criteria: - Able to understand the purpose and risks of the study; willing and able to adhere to scheduled visits, treatment plans, laboratory tests, and other study evaluations and procedures. - Give written informed consent. - Be males or nonpregnant, nonlactating females judged to be in good health, based on the results of medical history, physical examination, vital signs, 12-lead ECG, and clinical laboratory findings. - Have a body mass index (BMI) between 18 and 32 kg/m2, inclusive, and a body weight more than 50 kg (110 pounds). - Be a nonsmoker. Use of nicotine or nicotine-containing products must be discontinued at least 90 days prior to the first dose of study drug. - Be willing to comply with study restrictions - Have suitable veins for multiple venipuncture/cannulation. - Female subjects must be either of nonchildbearing potential (i.e., postmenopausal or permanently sterilized) or use highly effective contraception with low user-dependency. - The only acceptable method of highly effective contraception with low user-dependency is an intrauterine device (IUD). Use of hormonal contraception (by any route, including intrauterine hormone releasing systems) or hormone replacement therapy is NOT acceptable. Exclusion Criteria: - Be an employee or immediate family member of the Clinical Research Unit or Corcept. - Have been previously enrolled in any study of relacorilant. - Have multiple drug allergies or be allergic to any of the components of relacorilant. - Have a condition that could be aggravated by glucocorticoid blockade (e.g., asthma, any chronic inflammatory condition). - Have a history of malabsorption syndrome or previous gastrointestinal surgery, with the exception of appendectomy and cholecystectomy, which could affect drug absorption or metabolism. - Current, or previous within a 1-year period, alcohol or substance abuse. - In the 2 calendar months before first study drug administration, have donated/lost blood or plasma in excess of 400 mL. - In the 30 days before first study drug administration, have participated in another clinical trial of a new chemical entity or a prescription medicine. - Have a positive test for alcohol or drugs of abuse at screening or first admission. - Have clinically relevant abnormal findings on vital signs, physical examination, laboratory screening tests, or 12-lead ECG, at screening and/or before first study drug administration, including but not limited to**: - QT interval corrected for heart rate (QTc) using Fridericia's equation (QTcF) >450 ms (from mean of 3 supine ECGs, performed at least 2 minutes apart) - Stage 2 or higher hypertension (supine/semi-recumbent systolic blood pressure [SBP] >160 mmHg, diastolic blood pressure [DBP] >100 mmHg; based on mean of duplicate values recorded at least 2 minutes apart) - Stage 1 hypertension (supine/semi-recumbent SBP 140-160 mmHg, DBP 90-100 mmHg; based on mean of duplicate values recorded at least 2 minutes apart) associated with indication for treatment i.e., evidence of end-organ damage, diabetes, or a 10-year cardiovascular risk, estimated using a standard calculator, (e.g., QRISK2-2016) greater than 20% - Estimated glomerular filtration rate <60 mL/minute/1.73 m2, estimated using the Chronic Kidney Disease Epidemiology Collaboration method (Levey 2009) - Hypokalemia (potassium below lower limit of normal) - Alanine aminotransferase (ALT), aspartate amino transferase (AST), and/or gamma- glutamyl transferase (GGT) >1.5 times the upper limit of normal (ULN) - Seropositive for hepatitis B, hepatitis C, or human immunodeficiency (HIV) viruses **For purposes of qualifying any given subject for study participation, out-of-range values may be repeated once. - Have any medical or social reasons for not participating in the study raised by their primary care physician. - Have any other condition that might increase the risk to the individual or decrease the chance of obtaining satisfactory data, as assessed by the Investigator. - Taken any prohibited prior medication within protocol designated timeframes, such as or including any glucocorticoid, strong inducers, inhibitors or substrates of CYP enzymes involved in drug-drug-interactions, hormonal contraception or hormone replacement therapy. |
