Clinical Trial Summary

The study is a phase I/II, double-blind, placebo-controlled, randomized cross-over clinical trial of tocilizumab (TCZ) or placebo in HIV-infected subjects receiving antiretroviral therapy with suppressed viral replication and CD4+ T cell count ≥350 and ≤1,000 cells/mm3)

Clinical Trial Description

DESIGN The study is a phase I/II, double-blind, placebo-controlled, randomized cross-over clinical trial of tocilizumab (TCZ) or placebo in HIV-infected subjects receiving antiretroviral therapy with suppressed viral replication and CD4+ T cell count ≥350 and ≤1,000 cells/mm3) DURATION 40 weeks during cross-over treatment periods total per subject. SAMPLE SIZE 30 subjects with complete data up to week 30. Up to 36 subjects may be enrolled in order to achieve an estimated final sample size of 30 participants with complete data up to week 30. POPULATION HIV-infected male and female subjects from 18 through 60 years of age receiving combination antiretroviral therapy (ART) without changes in the 24 weeks prior to enrollment (changes for reasons other than virologic failure allowed up to 8 weeks prior to enrollment), with a suppressed plasma HIV RNA (<200 copies/mL, one blip up to <1,000 copies/mL permitted) for at least 96 weeks and a CD4+ T-cell count ≥350 and ≤1,000 cells/mm3 at the time of study enrollment. REGIMEN Subjects will be randomized 1:1 to one of the following arms: ARM A: TCZ, 4 mg/Kg by IV infusion over 60 minutes (not to exceed 400 mg) once at study entry, followed by TCZ, 8 mg/Kg by IV infusion over 60 minutes (not to exceed 800 mg) at weeks 4, and 8 and THEN placebo by IV infusion at weeks 20, 24, and 28. ARM B: Placebo by IV infusion at study entry followed by placebo by IV infusion at weeks 4 and 8, and THEN TCZ, 4 mg/Kg (not to exceed 400 mg) by IV infusion over 60 minutes once at week 24, followed by TCZ, 8 mg/Kg (not to exceed 800 mg) by IV infusion over 60 minutes at weeks 24 and 28. ;
