Immune-based Therapy Pilot Study for the Treatment of Primary HIV Infection (PHI-IMD).
Immune-based Therapy Pilot Study for the Treatment of Primary HIV Infection With the Objective to Induce a Strong Specific HIV Immune Response Able to Control Viral Replication Without Highly Active Anti-Retroviral Therapy (HAART)

Pilot study for the treatment of primary HIV infection with the objective to induce a strong specific HIV immune response able to control viral replication without HAART.

Pilot and open RCT in 20 patients with primary HIV-1 infection who were randomized to one of these two arms: 1) Control arm (A), Tenofovir +Lamivudine + Lopinavir-ritonavir (Kaletra) at standard doses for 44 weeks (W44); a short treatment interruption (TI) was performed at W36, and HAART was restarted for 8 weeks when plasma HIV-1 RNA viral load (pVL) rebounded>200 copies/mL. At W44 HAART was stopped and patients were followed for 48 additional weeks (W92). 2) Immune-based arm (B), same HAART schedule plus oral cyclosporine A (CsA)(serum levels 250-350 mcg/L) for the first 8 weeks of HAART. During the TI, patients received sc GM-CSF (250 mcg TIW) plus weekly sc pegylated-interferon a2b (Peg-INF)(1.5 mcg/kg/week). During the last 8 weeks of HAART (until W44), patients received daily sc low-dose interleukin-2 (IL-2)(0.75 MU/kg QD). The primary endpoint was pVL <1000copies/mL (<3.0 log10/mL) at 12 (W56) and at 48 (W92) weeks after stopping HAART. Sample size was calculated in order to detect a pVL difference of 1.5log10 copies/mL at 12 (W56) weeks after stopping HAART between the control and the immune-based arms with a power of 80% and a level of significance of0.05.

Interventional
Phase 4
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
HIV
  • Drug: HAART

    Patients assigned to this arm will receive Trizivir and kaletra. After the first 9 months of HAART, all patients will stop HAART until HIV viral load in plasma became detectable (>200 copies/mL). Then, they will re-start HAART plus low doses of IL-2 during 2 months.

    All patients will be followed-up during 1 year.

    Other Names:
    • Viread
    • Epivir
    • Kaletra
  • Drug: HAART + Immunotherapy

    Patients assigned to this arm will receive Trizivir + Kaletra + cyclosporin A during the first two months. This group also will receive GM-CSF plus pegylated-interferon-alpha until HIV viral load in plasma became detectable (>200 copies/mL). Then, they will re-start HAART plus low doses of IL-2 during 2 months. At this moment they will stop HAART.

    All patients will be followed-up during 1 year.

    Other Names:
    • Cyclosporine A
    • GM-CSF
    • Peg-IFN
    • Interleukin-2
  • Active Comparator: HAART
    Patients assigned to this arm will receive standard HAART
    Intervention: Drug: HAART
  • Experimental: HAART + Immunotherapy
    Patients assigned to this arm will receive HAART plus cyclosporin A during the first two months and after that will receive IFN, GM-CSF and IL-2.
    Intervention: Drug: HAART + Immunotherapy
