Safety, Pharmacokinetics, and Pharmacodynamics of MK-2248 in Participants With Hepatitis C (MK-2248-002)
5 de junio de 2015 actualizado por: Merck Sharp & Dohme LLC
A Multiple Dose Study to Evaluate Safety, Pharmacokinetics, and Pharmacodynamics of MK-2248 in Subjects With Hepatitis C Infection
The objective of this study is to identify a safe dose of MK-2248 in participants with Hepatitis C Virus (HCV) that mediates at least a 3 log10 reduction in viral load (VL) from baseline.
It is anticipated that once-daily administration of a safe and well tolerated dose of MK-2248 will reduce VL by at least 3 log10 IU/mL.
Descripción general del estudio
Descripción detallada
In this Phase 1b study, the pharmacokinetic (PK), pharmacodynamic (PD), and safety profile of MK-2248 in HCV-infected participants will be evaluated as follows: Part I will assess sequentially ascending MK-2248 doses from 200 mg to ≤800 mg over 4 panels (A, B, C, and D).
Part II will assess sequentially ascending MK-2248 doses from 200 mg to ≤800 mg over 4 panels (E, F, G, and H).
Part III will assess sequentially ascending MK-2248 doses ranging up to ≤800 mg in 2 panels (I and J).
The potential relationship between plasma MK-2248 levels and VL reduction will be determined.
