Brief Summary

Official Title: “International, Multicenter, Randomized, Non-comparative Controlled Study of Therapeutic Intensification Plus Immunomodulation in HIV-infected Patients With Long-term Viral Suppression”

Viral eradication in selected HIV-infected patients is possible with intensive antiretroviral therapy plus immunomodulation

Study Type: Interventional

Study Design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study

Study Primary Completion Date: October 2011

Detailed Clinical Trial Description

The overall strategy of the ERAMUNE 01 Trial is to treat selected patients with an optimal synergistic antiretroviral regimen plus one or more immunomodulating agents. Among immunomodulating treatments the candidates include therapies from two functional classes: 1) agents that target actively replicating cells and 2) agents activating latently infected cells31.

The novelty of this approach is three-fold: first, the use of highly potent antiretroviral therapy combining drugs with different HIV enzymes targets or receptors and different penetrations in cells, with the aim to suppress virus to truly undetectable levels as measured by the most sophisticated viral quantification techniques; secondly, the addition of an immunomodulatory therapy that specifically targets viral reservoirs to this intensification strategy; and lastly, the rigorous selection of patients having already a low HIV reservoir as measured by peripheral blood HIV DNA content. To our knowledge, this type of strategy has not been implemented. We believe this strategy is feasible.

Intervention(s) in this Clinical Trial

  • Drug: HAART Intensification
    • Current ART regimen plus raltegravir and maraviroc Raltegravir : 400 mg PO BID for 56 weeks Maraviroc : 150, 300 or 600 mg PO BID depending on concomitant ART treatment, for 56 weeks
  • Biological: Immunomodulation
    • 2 cycles of 3 injections (1 per week) of recombinant human Interleukin-7 (r-hIL-7 / CYT107) at a 20 µg/kg dose. First cycle at Week 8, second cycle at Week 28

Arms, Groups and Cohorts in this Clinical Trial

  • One HIV plasma viral load (RNA) documented at least 3 years prior to entry, and at least 2 HIV plasma viral loads (RNA) documented per year thereafter
  • HIV plasma viral load (RNA) ≤ 500 copies/ml at least 3 years prior to entry and HIV plasma viral load ≤ 500 copies/ml for ≥ 90% of the measures thereafter
  • HIV plasma viral load (RNA) below the limit of detection for all values within the past year. Note: the assay used must have a lower limit of detection of 75 copies/ml or less

  • All subjects must agree not to participate in the conception process (e.g. active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization), and if participating in sexual activity that could lead to pregnancy, the subject/partner must use at least two reliable forms of contraceptives (condoms, with or without spermicidal agent, a diaphragm or cervical cap with spermicide, an IUD, or hormone-based contraception), while receiving study treatment and for 6 weeks after stopping study treatment
  • Ability and willingness to provide informed consent.

Exclusion Criteria:
