Clinical Trial Summary

The goal of this study was to compare the characteristics of a new tablet formulation versus an oral solution of CIN-107 (baxdrostat) in terms of CIN-107 levels over time in the blood and to compare the effect of food on these parameters in healthy volunteer participants who received the CIN-107 tablet under fed versus fasted conditions.

Description:

The goals of this study were to:

1. To assess the safety and tolerability of single doses of CIN-107 tablet and oral solution in healthy participants.

2. Compare CIN-107 levels over time in the blood in participants after dosing between a tablet formulation of CIN-107 as compared to the oral solution.

3. Compare the CIN-107 levels over time in the blood in participants following dosing with a CIN-107 tablet after a meal versus in the fasted state.

Participants took either the oral solution or a tablet of CIN-107 and had their safety and blood levels of CIN-107 measured over several days following administration of CIN-107 tablet either in the fasted state or after a meal. The CIN-107 blood levels over time were compared between the groups given either the oral solution or the tablet and between the group given the CIN-107 tablet with a meal versus in the fasted state.

11. Positive for human immunodeficiency virus (HIV) antibody, hepatitis C virus (HCV) antibody, or Hepatitis B surface antigen (HBsAg).

12. Any other clinical laboratory values which are meaningfully outside of normal limits (based on laboratory normal range) in the opinion of the Investigator.

13. A known history of porphyria, myopathy, or an active liver disease.

14. Evidence or history of any clinically significant immunologic, hematologic, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, musculoskeletal, hepatic, psychiatric, neurologic, or allergic disease (including clinically significant or multiple drug allergies); surgical conditions; cancer (with the exception of basal or squamous cell carcinoma of the skin and cancer that resolved or has been in remission for >5 years prior to Screening); or any condition that, in the Investigator's opinion, may confound study procedures or results, impact subject safety, or interfere with the absorption, distribution, metabolism, or excretion of the study drug (appendectomy allowed, cholecystectomy prohibited).

15. Use of any prescription medications (including topicals) or over-the-counter medications (other than occasional use of acetaminophen or nonsteroidal anti-inflammatory drugs, such as ibuprofen or naproxen, according to the package insert); herbal supplements; dietary supplements; or nutraceuticals within 14 days prior to the first dose of study drug, or 5 halflives, whichever is longer, or an unwillingness to refrain from these medications through discharge from the clinical unit. Note: Use of over-the-counter topical medications may be permitted in consultation with the Sponsor. In addition, medications for which 5 half-lives exceeds 14 days must be discussed with and approved by the Sponsor prior to subject enrollment.

16. Corticosteroid use (systemic or extensive topical) within 3 months prior to dosing.
