Inclusion Criteria:

  • Must agree to use an adequate method of contraception
  • Healthy men or non-pregnant, non-lactating healthy women of non-childbearing potential
  • Body mass index (BMI) of 19.0 to 32.0 kg/m^2 as measured at screening
  • Weight ≥50 kg at screening

Exclusion Criteria:

  • Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients
  • Presence or history of clinically significant allergy requiring treatment, as judged by the Investigator.
  • Significant serious skin disease, including rash, food allergy, eczema, psoriasis, or urticaria
  • History of clinically significant cardiovascular, renal, hepatic, chronic respiratory or gastrointestinal disease, bleeding disorder or abnormal bleeding, or clinically significant active bleeding, congenital or acquired clotting disorders, neurological or psychiatric disorder

  • History of any drug or alcohol abuse in the past 2 years
  • A confirmed positive alcohol urine test at screening or admission

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Dabigatran Etexilate (NIMP) and Relacorilant (IMP)

Arm Description

Following an overnight fast, participants will receive 75 mg dabigatran etexilate on Day 1, 400 mg dose of relacorilant QD on Days 3 to 13, and 75 mg dabigatran etexilate on Day 12. On Day 12, dabigatran etexilate will be dosed at approximately the same time as the relacorilant dose.

Outcomes

Primary Outcome Measures

Maximum Observed Plasma Concentration (Cmax) of Dabigatran When Administered With and Without Relacorilant
Area Under the Curve from Time 0 to the Time of Last Measurable Concentration (AUC0-last) of Dabigatran When Administered With and Without Relacorilant
Area Under the Curve from Time 0 Extrapolated to Infinity (AUC 0-inf) of Dabigatran When Administered With and Without Relacorilant

Secondary Outcome Measures

Plasma Concentrations of Relacorilant
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
Number of Participants with Clinically Significant Abnormalities in Blood Pressure and Heart Rate
Number of Participants with Clinically Significant Abnormalities in Electrocardiogram (ECG) Measurements
Number of Participants with Clinically Significant Abnormalities in Laboratory Safety Tests (Clinical Chemistry, Hematology, Urinalysis)

5. Study Description

Brief Summary
The primary objective is to determine the effect of relacorilant on the pharmacokinetics (PK) of the sensitive P-glycoprotein (P-gp) substrate dabigatran etexilate.
Detailed Description
The investigational medicinal product (IMP), relacorilant, and the non-investigational medicinal product (NIMP), dabigatran etexilate, will be used to evaluate the effect of relacorilant on the PK of the sensitive P-gp substrate, dabigatran etexilate in healthy participants. Participants will receive a single dose of dabigatran etexilate before and after administration of daily (QD) doses of relacorilant for 11 days. As all participants will receive the same treatments, the study will be open-label and no randomization is required.
