Official title

A Double-Blind, Randomized, Placebo-Controlled, Multi-Centre, Dose-Ranging, Parallel Group, Phase II Study to Assess Efficacy, Safety/Tolerability, and Pharmacokinetics of a Thrombopoietin Receptor Agonist, SB-497115-GR, When Administered as 30, 50, and 75 mg Once Daily for 12 Weeks in Subjects With

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 as a treatment for patients with chronic hepatitis C-related thrombocytopenia who are potential candidates for antiviral treatment with pegylated interferon and ribavirin. The study will be conducted in two phases, Parts 1 and 2. In Part 1, study subjects will be randomized to 4 weeks of SB-497115-GR or placebo administered daily without antiviral therapy. Subjects who successfully complete Part 1 (platelet count 70,000/µL for Pegasys and platelet count 100,000/µL for PEG-Intron) will then proceed to Part 2. In Part 2, subjects will receive an additional 8 weeks of SB-497115-GR or placebo administered daily with antiviral therapy.
