A Two-Part, Single-Dose Study of the Pharmacokinetics of MK-8931 in Subjects With Renal Insufficiency (MK-8931-009 [P08535])

23. januar 2015 opdateret af: Merck Sharp & Dohme LLC

An Open-Label, Two-Part, Single-Dose Study to Investigate the Pharmacokinetics of MK-8931 in Subjects With Renal Insufficiency (Protocol No. MK-8931-009 [P08535])

This study will assess the pharmacokinetics of MK-8931, a ß-secretase inhibitor, in participants with renal insufficiency. In Part 1 of the study, pharmacokinetics of MK-8931 in participants with severe renal disease and in healthy matched control participants will be studied. If data from Part 1 confirms that severe renal impairment does not alter the pharmacokinetics of MK-8931 to the extent requiring dosage adjustment, then no further study will be required and Part 2 will be optional. If the data does not support this conclusion, then Part 2 will be conducted to study the pharmacokinetics of MK-8931 in participants with moderate and mild renal impairment compared to healthy matched controls.

  • Stable baseline health based on medical history, physical examination, vital signs, and laboratory tests

Inclusion Criterion Specific to Healthy Participants:

  • eGFR ≥80 mL/min/1.73m^2

Exclusion Criteria:

  • Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism or excretion of any drug, including history or presence of inflammatory bowel disease, gastrointestinal or rectal bleeding; presence of active ulcer; history of major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, or bowel resection; history of pancreatic injury or pancreatitis; history or presence of liver disease or liver injury; history of urinary obstruction or difficulty in voiding
  • History of any infectious disease within 4 weeks prior to drug administration
  • Positive for hepatitis B surface antigen (HBsAg), hepatitis C antibodies (HCV) or human immunodeficiency virus (HIV)
  • History of risk factors for Torsades de Pointes (e.g., heart failure/cardiomyopathy or family history of Long QT Syndrome)
  • Participant has had a kidney removed or has a functioning renal transplant
  • History of alcohol or drug abuse in the past 2 years
  • Blood donation or loss of significant volume of blood in the past 60 days prior to dosing
  • Previously received MK-8931
  • History of significant multiple and/or severe allergies (including latex allergy), or anaphylactic reaction or significant intolerability to prescription or non-prescription drugs or food
  • History of malignancy occurring within the 5 years immediately before screening, except for a participant who has been adequately treated for basal cell or squamous cell skin cancer; or in situ cervical cancer; or

localized prostate carcinoma; or has undergone potentially curative therapy with no evidence of recurrence ≥1 year post-therapy

Exclusion Criteria Specific to Renally Impaired Participants:

  • Rapidly fluctuating renal function as determined by historical measurements
  • Suspected renal artery stenosis
