Brief Summary:
The study will be a randomized double blind placebo controlled dose rising study in Interferon alpha IFN-alpha non-responder HCV infected patients or HCV patients who have relapsed following IFN-alpha therapy Eligible subjects must have compensated liver disease and serum HCV RNA concentrations above 100000 IUmL at screening The study will include both a single dose period for the evaluation of acute toxicity and single dose pharmacokinetics and a consecutive multi-dose period for the determination of longer-term safety multiple-dose pharmacokinetics and antiviral activity The objectives of this study are to evaluate the safety tolerability and antiviral activity of escalating single and multiple doses of XTL 2125 in patients with chronic hepatitis C virus infection and to assess the single- and multiple-dose pharmacokinetics of XTL 2125
Detailed Description:
The study will be of a randomized double blind placebo controlled multicenter design with sequential ascending doses of XTL 2125 in HCV-infected patients with compensated liver disease who did not respond to IFN-alpha therapy or relapsed following this therapy
This study will include both a single dose session and a multiple dose session In the single dose session patients will be randomized to receive a single oral dose of either XTL 2125 or placebo on Day 1 in a dose-escalating design followed by a multiple dose session that will start on day 8 and will continue for 14 days The same patients will receive XTL 2125 three times daily at the same dose administered in the single dose session
The following doses will be administered to groups of 8 patients each 10 mg 25 mg 50 mg 150 mg 300 mg and 450 mg Within each group 6 subjects will receive XTL 2125 and 2 subjects will receive placebo No patient will be enrolled in more than one dose level Doses should be administered one hour before meals with 240 cc water
Additional patients may be enrolled at previous or intermediate doses to obtain additional safety or pharmacokineticpharmacodynamic data and to more accurately define the Maximum Tolerated Dose MTD
The MTD will be defined as the last dose level that is successfully administered with a decision to escalate to the next level If the decision not to escalate to the next level is made then a cohort that receives XTL 2125 at a dose half-way between the last tolerated dose and the non-tolerated dose may be enrolled at the discretion of the Sponsor If this dose is successfully administered without violating the dose escalation rules then this interim dose will be considered the MTD
Six dose cohorts will be prospectively indicated although additional cohorts may be scheduled at intermediate doses if warranted by the data
