Brief Summary:
iHIVARNA-01 is a novel therapeutic vaccine for the treatment of HIV-1-infected patients based on in vivo modification of DCs. It consists of HIVACAT-TriMix: mRNA encoding a mixture of APC activation molecules (CD40L, a constitutively active variant of TLR4 and CD70) and the HIV target antigens contained in HIVACAT to be administered through the intranodal route. iHIVARNA-01 aims to achieve the 'functional cure' of HIV infection, i.e. controlling viral replication in the absence of anti-retroviral therapy.

Detailed Description:

Objective: To evaluate the safety and immunogenicity of iHIVARNA-01 as a new therapeutic vaccine in HIV infected patients.

Study design and duration: Phase IIa, multicentre double-blind placebo controlled intervention study. Each patient will be followed for 30 weeks. The study duration will be 38 weeks from inclusion of the first patient.

Sites: Erasmus MC, Rotterdam The Netherlands (sponsor), Hospital Clínic de Barcelona and Institut de Recerca de la Sida - Caixa, Barcelona, Spain, Instituut voor Tropische Geneeskunde Antwerp, Belgium and Vrije Universiteit Brussel/UZ Brussel, Belgium

Study population: Chronically HIV-1- infected patients under stable cART with plasma viral load (pVL) ≤ 50 copies/ml and stable CD4+ T-cell counts ≥ 450/μl, aged 18 years or above.

Sample size: after recruitment and screening, 70 patients will be included and randomized to one of the study-arms.

Intervention: One group (n=40) receives the HIVACAT-TriMix (300 microgram TriMix + 900 microgram HIVACAT) vaccine intranodally on three occasions with a two-week interval. One control group (n=15) receives TriMix only (300 microgram TriMix) and one group (n=15) receives saline intranodally on three occasions with a two-week interval. Two weeks after the last vaccination cART treatment will be interrupted. If plasma virus is detectable, cART will be re-initiated twelve weeks after treatment interruption. cART can always be re-initiated for medical reasons, as judged by the clinical investigator.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 33 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase IIa Randomized, Placebo Controlled, Double Blinded Study to Evaluate the Safety and Immunogenicity of iHIVARNA-01 in Chronically HIV-infected Patients Under Stable Combined Antiretroviral Therapy

Primary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 [ Time Frame: week 6 ]
    • Grade 3 or above local adverse event (pain, cutaneous reactions including induration).
    • Grade 3 or above systemic adverse event (temperature, chills, headache, nausea, vomiting, malaise, and myalgia).
    • Grade 3 or above other clinical or laboratory adverse event confirmed at examination or on repeat testing respectively.

    Any event attributable to vaccination leading to discontinuation of the immunisation regimen.

  2. Immunogenicity [ Time Frame: week 6 ]
    Change from baseline immunogenicity as measured by ELISPOT at week 6 and 18, i.e. two weeks and 14 weeks after the last immunization compared to both control groups

Secondary Outcome Measures :
  1. Immunogenicity [ Time Frame: week 10, 18 and 30 ]
    o magnitude and the kinetics of the HIV-specific CD4+ and CD8+ T cell responses after immunization (ELISPOT) as defined by the increase in the number of spot forming units and if positive the number of poly-functional T cells as determined by intracellular cytokine staining, (ICS).

  2. Time to viral rebound [ Time Frame: week 6-18 ]
    time until viral rebound (defined as two consecutive measurements of plasma viral load > 1000 copies/mL separated by at least 15 days) after discontinuation at week 6.

  3. Plasma viral load [ Time Frame: week 6-18 ]
    plasma viral load in vivo after ATI, week 6-18

  4. Functional cure [ Time Frame: week 18 and 30 ]
    proportion of patients with viral load below detectable level of 50 copies/mL in plasma after ATI, week 18 and 30

  5. Primary immune response against vaccine [ Time Frame: week 6 ]
    Change in frequency of at least 0.7log10 HIV-specific T-cell responses between baseline and week 6

  6. CD8 T cell mediated viral suppression [ Time Frame: week 4 ]
    the in vivo vaccine-induced capacity of ex-vivo CD8 T cells to suppress HIV growth in autologous CD4 T cells

  7. Viral reservoir [ Time Frame: week 4 and 6 ]
    effect on reservoir as measured by changes in the proviral DNA copy numbers per million cells and the intracellular viral RNA copy numbers per million cells during and after immunization

  8. Viral Immune escape [ Time Frame: week 18 ]
    viral immune escape: change in % mutated epitopes from pre-cART to post-ATI

  9. Transcriptomics [ Time Frame: week 6 and 18 ]
    host protein mRNA expression profiles in whole blood
