Current Primary Outcome Measures  ICMJE
 (submitted: April 9, 2015)
Dose limiting toxicity (DLT) [ Time Frame: week 8 ]
Safety as measured by dose limiting toxicity (DLT), defined as:
  • 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
Original Primary Outcome Measures  ICMJE Same as current
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: April 9, 2015)
  • Immunogenicity (number of spot-forming cells (SFC) per million of IFN-gamma producing PBMC directed against HIV-1 sequences) as measured by ELISPOT at baseline and weeks 4, 6, 8 and 24. [ Time Frame: week 24 ]
    ELISPOT assays will be performed to measure the numbers of IFN-gamma producing PBMC directed against HIV-1 sequences. Results were expressed as the number of spot-forming cells (SFC) per million of PBMC after substracting the background.
  • Effect of vaccination on plasma viral load (pVL) (ultrasensitive assay) using the Single copy assay (SCA) at screening and weeks 2, 4, 6, 8 and 24 [ Time Frame: week 24 ]
    Effect of vaccination on plasma viral load (pVL) (ultrasensitive assay) at screening and weeks 2, 4, 6, 8 and 24. Low-level HIV-1 viral loads will be measured using the Single copy assay (SCA). The limit of detection of the SCA will be standardized to the highest limit for any individual (0.7 copies/ml)
  • Cell-associated HIV-1 RNA (CA-RNA) quantification at week 0, 4, 6, 8 and 24 [ Time Frame: week 24 ]
    Intracellular HIV RNA species at week 0, 4, 6, 8 and 24. Cell-associated HIV-1 RNA (CA-RNA) will be isolated from cryopreserved PBMCs. CA-RNA will be quantified using a real-time PCR approach with primers/probes targeting conserved regions of the HIV long terminal repeat (LTR)/gag
  • Genome wide transcriptome and microRNA analysis at weeks 0 and 6 [ Time Frame: week 6 ]
    Transcriptome analysis at weeks 0 and 6 Genome wide transcriptome and microRNA analysis on the same PBMC samples will be performed. Plasma samples will be analyzed for protein expression patterns using multiplex ELISA (Luminex technology). All data will be integrated into the multidimensional database "VASP" a web based "-omics" data analysis and storage pipeline developed by Erasmus University Rotterdam to ensure data consistency and ease of analysis to all partners. Advanced bioinformatics and statistical analysis will be used to reveal the impact of vaccination on the virus-host interaction in chronic HIV infection

    Cohort 1 (control group) 3 patients will receive 100 μg of mRNA (i.e. 100 μg TriMix mRNA).If two or more of the three patients have a dose limiting toxicity (DLT), DSMB should be consulted and study will be terminated.
