About Vicriviroc Ongoing Phase III Studies
Building on the results of the VICTOR-E1 study, Schering-Plough is currently enrolling patients in two large global Phase III clinical studies with vicriviroc administered once-daily as a single 30 mg tablet in adult treatment-experienced HIV patients with R5-type virus only.
The two ongoing Phase III studies, known as VICTOR-E3 and VICTOR-E4 (Vicriviroc in Combination Treatment with an Optimized Antiretroviral Therapy Regimen in HIV-Infected Treatment-Experienced Subjects), evaluate the virologic benefit of adding vicriviroc 30 mg once daily to an optimized background therapy compared to a control group receiving new optimized background therapy alone. The optimized background therapy must include at least two drugs to which the patient's HIV is susceptible. Patients coinfected with hepatitis B or C may be included in these studies and there are no exclusions of commonly prescribed drugs or need for dose adjustments based on the known vicriviroc drug-drug interaction profile. The two studies are currently enrolling approximately 375 patients each at more than 160 sites in North America, Latin America, Europe, Australia and South Africa.
