About

The purpose of this study is to compare the plasma pharmacokinetics (PK) of single doses of MK-3682B, a fixed dose combination (FDC) tablet containing uprifosbuvir (MK-3682) + grazoprevir (MK-5172) + ruzasvir (MK-8408) in participants with moderate (Part 1) and severe (Part 2) renal insufficiency (RI) to plasma PK in healthy participants.

Enrollment: 16 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

All Participants:

• Healthy adult males or females 18-80 years of age at screening
• Continuous non-smokers or moderate smokers (≤ 20 cigarettes/day or the equivalent) and agrees to consume no more than 10 cigarettes per day during the study period
• BMI ≥ 18 and ≤ 40.0 kg/m^2
• Agrees not to become pregnant or father a child during participation in the study
• Females of childbearing potential must either be abstinent for 14 days prior to dosing and throughout the study or be using an acceptable birth control method
• Vasectomized or non-vasectomized males must agree to use a condom with spermicide or abstain from sexual intercourse from the first dose until 90 days after dosing
• Males must agree not to donate sperm from dosing until 90 days after dosing

Moderate and Severe RI Participants:

• Baseline health is judged to be stable based on medical history, physical examination, laboratory profiles, vital signs, or electrocardiograms (ECGs), as deemed by the Investigator
• Has had no clinically significant change in renal status at least 1 month prior to dosing and is not currently or has not previously been on hemodialysis
• Moderate RI: has baseline eGFR ≥ 30 mL/min/1.73m^2 and < 60 mL/min/1.73m^2, based on the Modification of Diet in Renal Disease (MDRD) equation at screening
• Severe RI: has baseline eGFR ≥ 15 mL/min/1.73m^2 and < 30 mL/min/1.73m^2, based on the MDRD equation at screening

Healthy Participants:

• Is within ± 10 years of the mean age of moderate and severe RI arms
• BMI is within 10% of the mean BMI of participants with moderate and severe RI arms
• Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs, or ECGs, as deemed by the Investigator
• Baseline CLcr ≥ 80 mL/min based on Cockcroft-Gault equation at screening

Exclusion criteria

• Is mentally or legally incapacitated or has significant emotional problems at the time of the screening
• History or presence of clinically significant medical or psychiatric condition or disease in the opinion of the Investigator
• History of any illness that, in the opinion of the Investigator, might confound the results of the study or poses an additional risk by participating in the study
• Is female and pregnant or lactating
• Positive results for the urine or saliva drug screen or urine or breath alcohol screen at screening or check-in unless the positive drug screen is due to prescription drug use that is approved by the Investigator and Sponsor
• Positive results at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV)
• Seated heart rate is equal to or lower than 44 beats per minute (bpm) or higher than 100 bpm at screening
• Has had a renal transplant or has had nephrectomy
• Donation of blood or had significant blood loss within 56 days prior to dosing of study drug, or donation of plasma within 7 days prior to dosing
• Has participated in another clinical trial within 28 days prior to dosing of study drug

16 participants in 3 patient groups

Moderate RI Participants

Experimental group

Description:

Participants with an estimated glomerular filtration rate (eGFR) of ≥30 mL/min/1.73m\^2 to \<60 mL/min/1.73m\^2 take 2 MK-3682B FDC tablets on Day 1 after fasting for 10 hours.

Treatment:

Drug: MK-3682B

Severe RI Participants

Experimental group

Description:

Participants with an eGFR of ≥15 mL/min/1.73m\^2 to \<30 mL/min/1.73m\^2 take 2 MK-3682B FDC tablets on Day 1 after fasting for 10 hours.

Treatment:

Drug: MK-3682B

Healthy Participants

Experimental group

Description:

Healthy participants (creatinine clearance \[CLcr\] ≥80 mL/min) take 2 MK-362B FDC tablets on Day 1 after fasting for 10 hours. Healthy participants are matched to RI participants based on mean age, body mass index (BMI) and gender.
