Scientific titleA phase I/II trial to assess the safety and immunogenicity of a plasmid DNA-MVA prime boost HIV-1 vaccine candidate among volunteers in Dar es Salaam, Tanzania
Study acronymHIVIS 03
Study objectivesDelivery of plasmid DNA containing HIV-1 genes boosted with a pox vector (MVA) with analogous genes is safe and immunogenic among healthy Tanzanian volunteers.
Ethics approval(s)1. Research and Publications Committee of the Muhimbili University of Health and Allied Sciences (MUHAS). The study was approved on the 26/04/2006 (ref: MU/RP/AEC/Vol.V/76). As of 19/08/2008, the last amendments were approved on 19/06/2008 (ref: MU/DRP/PA/Vol. I/37)
2. National Ethics Committee at the National Institute for Medical Research (NIMR). The study was approved on 30/01/2006 (ref: NIMR/HQ/R.8a Vol.IX/410). As of 19/08/2008, the last amendments were approved on 19/06/2008 (ref: MU/DRP/PA/ Vol.I/37)
Health condition(s) or problem(s) studiedHIV-1
InterventionThe clinical staff and participants are blinded throughout the trial. The immunological laboratory is blinded during the study.

Priming injections: Injections of seven plasmids containing HIV-1 env subtype A, B and C, gag subtype A and B, RTmut and rev subtype B.

The participants were randomly allocated to the following four arms:
Arm I (n = 20): DNA 3.8 mg (intramuscular [IM])
Arm II (n = 20): DNA 1.0 mg (intradermal [ID])
Arm IIIa (n = 10): saline placebo IM
Arm IIIb (n = 10): saline placebo ID

All injections were administered with the Bioject® device. The env and rev plasmids were injected in the left deltoid muscle and the gag and RT plasmids in the right deltoid muscle. Injections were given at month 0, 1 and 3.

Boost injections: One MVA-CMDR given as an IM or ID injection (with needle and syringe) at a dose of 10^8 pfu in the left deltoid muscle. The MVA contains analogous HIV-1 genes from subtype A/E. It will be given 6 months after the last DNA/placebo injection.

The second MVA boost is planned to be given at 80 weeks (6 months after the first MVA boost). The participants will be formally re-recruited for the second MVA boost. This phase of study will be funded by the European and Developing Countries Clinical Trials Partnership (EDCTP), under the TAMOVAC-I Project.

Pharmaceutical study type(s)
PhasePhase I/II
Drug / device / biological / vaccine name(s)
Primary outcome measure1. Safety:
1.1. Samples for routine biochemistry and haematology (see inclusion criteria) were obtained at screening, before and 2 weeks after each immunisation, and 3 month after the last DNA and MVA immunisation
1.2. 12-lead electrocardiograms were performed before and 2 weeks after the MVA injection
1.3. Clinical adverse reactions and vital signs at 10 and 30 minutes, in addition a contact was made by telephone 1-3 days after each injection
1.4. A 7-day diary card (including standardised measurements of body temperature) was filled in and presented at the visit 2 weeks after each injection, when direct questions were asked on the basis of the diary card
2. Specific reactivity to HIV-1 peptides in IFN-gamma enzyme-linked immunosorbent spot (ELISpot), performed on fresh peripheral blood mononuclear cell (PBMC) before the first DNA and the MVA immunisation and 2 weeks after the last DNA and MVA immunisation
Secondary outcome measures1. The following will be performed on fresh PBMC before the first DNA and the MVA immunisation and 2 weeks after the last DNA and MVA immunisation:
1.1. Specific reactivity to HIV-1 peptides in IL-2 ELISpot
1.2. Lymphoproliferation to inactivated whole HIV-1 virions
2. A qualitative and quantitative presence of necessary infrastructure and human capacity to conduct HIV-related vaccine studies at MUHAS
Overall study start date20/02/2007
Completion date31/12/2009

4. Able to give informed consent
5. Literacy corresponding to a minimum of 7 years of primary education
6. Resident in Dar es Salaam, and willing to remain so for the duration of the study
7. At low risk of HIV infection, defined as the absence of an identifiable risk factor/ behaviour:
7.1. Sexual partner with HIV

11. Good health as determined by medical history, physical examination, clinical judgment and by key laboratory parameters (reference ranges are in accordance with data generated at MUHAS for haematology values, and that generated at Mbeya (MMRP) for biochemical parameters. Exclusion by presence of Diabetes mellitus will be based on the WHO cut-off value of a fasting blood glucose <7.8 mmol/l). Hence no grade 1 or higher routine laboratory parameters, defined as:

11.2. White blood cell count >1,300/mm^3
11.3. Granulocytes >6.4/mm^3

11.5. Platelets >120,000/mm^3
11.6. CD4 >400 cells/mm^3

11.10. Creatinine <1.25 x ULN
11.11. Urine dipstick for protein and blood: negative or trace. (If either is >=1+, obtain complete urinalysis (UA). If microscopic UA confirms evidence of haematuria or if proteinuria >=1+, the volunteer is ineligible)
Key exclusion criteria1. Active tuberculosis or other systemic infectious process elicited by review of systems, physical examination and laboratory detection, such as detection of Hepatitis B surface antigen, or active syphilis
2. Have a history of immunodeficiency, chronic illness requiring continuous or frequent medical intervention

8. Are receiving immunosuppressive therapy such as systemic corticosteroids or cancer chemotherapy.
9. Have used experimental therapeutic agents within 30 days of study entry
10. Have received any live, attenuated vaccine within 60 days of study entry. (Note: Medically indicated subunit or killed vaccines {e.g., hepatitis A or hepatitis B] are not exclusionary but should be given at least 2 weeks before or after HIV immunisation to avoid potential confusion of adverse reactions)
11. Have previously received an HIV candidate vaccine
12. History of severe local or general reaction to vaccination defined as:
12.1. Local: Extensive, indurated redness and swelling involving most of the major circumference of the arm, not resolving within 72 hours
