NCT02099994

Brief Summary

The study is part of a long-term aim to develop an effective HIV-1 vaccine and will evaluate safety and immunogenicity of vaccines focusing T cell responses on the conserved region of the HIV-1 proteome. The vaccines used are pSG2.HIVconsv DNA (D), MVA.HIVconsv (M) and Ad35-GRIN (A), delivered in regimens AM, DDDAM and DeDeDeAM, where e indicates electroporation.

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Healthy adults aged 18-50
  • Willing to comply with the requirements of the protocol and available for follow-up for the planned duration of the study.
  • Written informed consent.
  • Willing to undergo HIV-1 testing, counselling and receive test results.
  • All female volunteers must be willing to undergo urine pregnancy tests
  • If sexually active using an effective method of contraception until at least 4 months after the last vaccination.
  • Willing to forgo donating blood during the study.

You may not qualify if:

  • Any relevant abnormality on history or examination including history of immunodeficiency or autoimmune disease, or use of systemic corticosteroids, immunosuppressive, antiviral, anticancer or other medication that, in the opinion of the Principal Investigator or designee, is clinically significant, within the previous 6 months. (Note: use of inhaled steroids for asthma or use of topical steroids for localized skin conditions will not exclude a volunteer from participation.)
  • Any clinically significant acute or chronic medical condition that is considered progressive or, in the opinion of the Principal Investigator or designee, would make the volunteer unsuitable for the study.
  • Any of the following abnormal laboratory parameters (1 abnormal test may be repeated once if thought to be due to a temporary condition):
  • Haematology
  • Haemoglobin \< 9.0 g/dl for women and \<11.0 g/dl for men
  • Absolute Neutrophil Count (ANC) ≤ 1000 /mm3 (≤ 1 x 109 /l)
  • Absolute Lymphocyte Count (ALC) ≤ 600 /mm3 (≤0.6 x 109 /l)
  • Platelets ≤100,000 /mm3, ≥ 550,000 /mm3 (≤ 100 /l, ≥ 550 /l)
  • Biochemistry
  • Creatinine \> 1.3 x upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) \> 2.5 x ULN
  • Alanine aminotransferase (ALT) \> 2.5 x ULN
  • Urinalysis- Clinically significant abnormal dipstick confirmed by microscopy:
  • Protein = 2+ or more
  • Blood = 2+ or more (for women: before or after menses)
  • +15 more criteria
