A Clinical Trial to Evaluate the Relative Bioavailability of PRAX-628

PHASE1COMPLETED

A phase I clinical trial to evaluate the relative bioavailability of PRAX-628 tablet formulation compared to capsule formulation.

Study details:

This Phase 1, randomized, open-label, 2-way crossover clinical trial is designed to investigate the relative bioavailability, pharmacokinetics (PK), safety, and tolerability of PRAX628 tablet formulation and PRAX-628 capsule formulation in healthy male or female participants.

  4. Female of non-childbearing potential by reason of surgery or at least 1 year post menopause
  5. Additional inclusion criteria apply and will be assessed by the study team

Exclusion criteria

  1. Any clinically significant abnormalities, medical, or psychiatric conditions identified by a detailed medical history, or physical examination
  2. Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs. Examples of such conditions include (but are not limited to):
  3. History of inflammatory bowel syndrome, gastritis, gastrointestinal or rectal bleeding
  4. History of major gastrointestinal tract surgery (ie, gastrectomy, bowel resection, cholecystectomy etc.)
  5. History or evidence of pancreatic injury or pancreatitis
  6. History or presence of impaired renal function supported by estimated glomerular filtration rate [eGFR]<60 mL/min/1.73m2 or clinically significant abnormal urinary constituents (eg, protein)
  7. History of cancer except for nonmelanoma skin cancer resected >2 years ago and that has been definitively treated and considered cured.
  8. History of any lifetime suicide attempt or active suicidal ideation with intent as indicated by a 'Yes' response to either Question 4 or 5 on the C-SSRS 'Baseline/ Screening' version
  9. History of left bundle branch block, arrhythmias, Brugada syndrome, congenital heart disease, familial short QT syndrome, or family (first degree relative) history of sudden death, ventricular or clinically significant arrhythmias, including idiopathic ventricular fibrillation.
  10. Abnormal standard 12-lead ECG after at least 5 minutes resting in the supine position
  11. Abnormal vital signs after at least 5 minutes resting in the supine position:
  12. Has any of the following: a serum total bilirubin value >1.1× the upper limit of normal (ULN), a serum alanine aminotransferase (ALT) value >1.5×ULN, or aspartate aminotransferase (AST) value >1.5×ULN
  13. Serology test positive for human immunodeficiency virus (HIV), or hepatitis B or C
  14. Known allergy or hypersensitivity to any component of the formulation of PRAX 628 or history of severe allergy or anaphylaxis to a drug, food, or other exposure
  15. Use of any experimental or investigational drug or device within 30 days prior to the first dose of study drug or 5 times the terminal half-life of the drug, whichever is longer
  16. Use of systemic prescription medications; or over-the-counter medication, including multivitamins; and dietary and herbal supplements within 2 weeks or 5 times the terminal half-life of the medication prior to the first dose of study drug (whichever is longer) and for the duration of the trial
  17. Donation of blood within 1 month prior to Screening, plasma within 1 week prior to Screening, or platelets within 6 weeks prior to Screening
  18. Any vaccination within 28 days of the first dose of study drug
  19. Additional exclusion criteria apply and will be assessed by the study team
