A Multiple-Dose Study to Evaluate MK-1075 in Hepatitis C Virus (HCV) Infected Participants (MK-1075-004)

13. April 2018 aktualisiert von: Merck Sharp & Dohme LLC

A Multiple-Dose Study to Evaluate the Safety, Pharmacodynamics and Pharmacokinetics of MK-1075 in GT3 and GT1 HCV Infected Patients

This study will evaluate safety, pharmacokinetics (PK), and the ability of MK-1075 to suppress viral load (VL) in HCV-infected participants during 7 days of once daily dose administration. The primary hypothesis is at a once-daily dose that is sufficiently safe and well tolerated in HCV-infected participants, the mean maximum HCV RNA (log10 IU/mL) reduction is at least 3 log10 IU/mL as compared to baseline following multiple dose oral administration of MK-1075 in HCV genotype 1 (GT1) and genotype 3 (GT3) infected participants.

Maßnahmenbeschreibung
Zeitfenster
Number of Participants Who Experienced an Adverse Event (AE)
Zeitfenster: Up to Day 42
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Up to Day 42
Number of Participants Who Discontinued Treatment Due to an AE
Zeitfenster: Up to Day 7
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Up to Day 7
Change From Baseline in Maximum log10 HCV RNA Following Multiple Dose Oral Administration of MK-1075
Zeitfenster: Day 1 (pre-dose, 2, 4, 8, 12, and 24 hours postdose); Days 3, 4, 5, 6 (pre-dose); Day 7 (predose, 4, 12, 24, 48, 72, 96, 120, and 192 hours postdose); Days 21, 28 and 42
Blood was collected on Days 1, 3, 4, 5, 6, 7, 21, 28 and 42, where baseline measurement was defined as the measurement obtained pre-dose on the first day of dosing. Change from baseline in log10 HCV RNA levels, was determined, and the maximum reduction in HCV RNA was analyzed by an ANOVA model with a fixed effect for treatment. The primary hypothesis is, with a posterior probability larger than 70%, there is at least a 3 log10 reduction from baseline in HCV RNA.
Day 1 (pre-dose, 2, 4, 8, 12, and 24 hours postdose); Days 3, 4, 5, 6 (pre-dose); Day 7 (predose, 4, 12, 24, 48, 72, 96, 120, and 192 hours postdose); Days 21, 28 and 42
