Hepatitis C

About this trial
This is an interventional treatment trial for Hepatitis C
Eligibility Criteria
Inclusion criteria:

- Body mass index (BMI) of 18 to 37 kg/m^2
- No clinically significant abnormality on electrocardiogram (ECG)
- Stable health
- Willing to use appropriate contraception throughout the study and for 90 days after last dose of study drug

- History of stroke, chronic seizures, or major neurological disorder
- History of clinically significant endocrine, gastrointestinal (excepting HCV infection), cardiovascular, hematological, hepatic, immunological, renal, respiratory, or genitourinary abnormalities or diseases
- History of neoplastic disease (exceptions of adequately treated non-melanomatous skin carcinoma or carcinoma in situ of the cervix, or other malignancies which have been successfully treated ≥10 years prior and unlikely to recur
- Positive Hepatitis B surface antigen
- Documented human immunodeficiency virus (HIV) infection
- Consumption of excessive amounts of alcohol, defined as greater than 2 glasses of alcoholic beverages (1 glass is approximately equivalent to: beer [284 mL/10 ounces],wine [125 mL/4 ounces], or distilled spirits [25 mL/1 ounce]) per day

- Current regular user (including "recreational use") of any illicit drugs or history of drug (including alcohol) abuse within approximately 2 months prior to enrollment
- Evidence or history of chronic hepatitis not caused by HCV including but not limited to non-HCV viral hepatitis, non-alcoholic steatohepatitis (NASH), drug induced hepatitis, autoimmune hepatitis
- Previous treatment with other HCV NS3/4A protease inhibitors
- Previous exposure to interferon-alpha and/or ribavirin within 3 months prior to study enrollment
- Clinical or laboratory evidence of advanced or decompensated liver disease; evidence of bridging fibrosis or higher grade fibrosis (Metavir score ≥3)
- Participation in another investigational study within 4 weeks prior to enrollment

Participants with genotype 1 (GT1) Hepatitis C Virus (HCV) will receive low dose MK-2748 daily for 7 days.
Participants with GT1 HCV will receive lower dose MK-2748 daily for 7 days.
Participants with GT1 HCV will be dosed with MK-2748 daily for 7 days based on the safety, pharmacokinetic, and/or pharmacodynamic data from Panels A (low dose) and B (lower dose).
Participants with GT1 HCV will be dosed with MK-2748 daily for 7 days based on the safety, pharmacokinetic, and/or pharmacodynamic data from Panels A (low dose), B (lower dose), and C.
Participants with GT1 HCV will be dosed with MK-2748 daily for 7 days based on the safety, pharmacokinetic, and/or pharmacodynamic data from Panels A (low dose), B (lower dose), C, and G.
Participants with genotype 3 (GT3) HCV were to receive low dose MK-2748 daily for 7 days. Panel D was omitted from the study design and participants were not enrolled in this panel.
Participants with genotype 3 (GT3) HCV will receive high dose MK-2748 daily for 7 days.
Participants with GT3 HCV will be dosed with MK-2748 daily for 7 days based on the safety, pharmacokinetic, and/or pharmacodynamic data from Panel E (high dose).
Participants with GT3 HCV will be dosed with MK-2748 daily for 7 days based on the safety, pharmacokinetic, and/or pharmacodynamic data from Panels E (high dose) and F.
Participants with GT3 HCV will be dosed with MK-2748 daily for 7 days based on the safety, pharmacokinetic, and/or pharmacodynamic data from Panels E (high dose), F, and I.
