Therapeutic vaccination (p24-VLP) of patients with advanced HIV-1 infection in the pre-HAART era does not alter CD4 cell decline.

In a randomized placebo controlled trial 304 HIV infected patients with CD4 cell counts below 350 cells/microL received therapeutic vaccination with: alum placebo (Group I, n = 102), p24-VLP 500 microg (Group II, n = 101) or p24-VLP 1000 microg (Group III, n = 101) p24-VLP monthly for six months. Over one year the average change in CD4 cell count did not differ significantly between groups (-32, -40 and -52 cells per microL respectively). There was also no difference between groups in progression to CDC category B or C events, or in adverse events.

A randomized, double-blind, placebo-controlled study of itraconazole capsules for the prevention of deep fungal infections in immunodeficient patients with HIV infection.

Objectives: To determine whether systemic or deep fungal infections can be prevented, a double-blind, placebo-controlled, phase III trial of itraconazole prophylaxis was undertaken in HIV-infected patients.

Methods: HIV-1 infected patients with CD4 counts < 300 cells/microL were treated with itraconazole (200 mg per day) or matching placebo and followed for 2 years. Development of deep fungal infections, episodes of mucocutaneous candidiasis, change in CD4 count, survival and safety data were collected at each study visit.

A phase III study of recombinant human interferon gamma to prevent opportunistic infections in advanced HIV disease.

The efficacy and safety of recombinant human interferon gamma (rIFN-gamma) in the reduction of opportunistic disease in patients with advanced HIV-1 infection are assessed. A 12-month double-blind, placebo-controlled, multicenter, Phase III trial of rIFN-gamma in HIV-positive patients with CD4 < 100 x 10(9)/liter on stable antiretroviral therapy. Eighty-four patients were allocated treatment on a 1:1 basis to rIFN-gamma or placebo.
