TRIAL DESCRIPTION
Public title TaMoVac-01
Official scientific title A Phase I/II trial to assess safety and immunogenicity of i.d. DNA priming, i.m. MVA and i.m. rgp140/GLA-AF boosting in healthy volunteers in Tanzania and to develop further HIV vaccine trial capacity building in Tanzania
Brief summary describing the background
and objectives of the trial
Availability of safe and efficacious vaccine is an important desired goal. Participation of developing countries in this effort is crucial. Following earlier investments through Swedish and EU support, a phase I/II trial has been concluded in Tanzania. The DNA-prime, MVA-boost was safe and induced strong cellular immune responses. We intend to further explore the safety and immunogenicity of boosting with two doses of rgp140 in the adjuvant GLA-AF, administered IM among the TaMoVac01 volunteers

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person
allocating the participants to the intervention arms
Masking If masking / blinding was used
Factorial: participants randomly allocated to either no,one,some or all interventions simultaneously Randomised Simple randomisation Allocation was determined by the holder of the sequence who is situated off site Masking/blinding used

Satisfactory completion of an assessment of understanding prior to enrolment defined as 90% correct answers after three opportunities to take test. 6. Basic abilities to read and write. 7. Resident in Dar es Salaam or Mbeya, and willing to remain so for the duration of the study 8. At low risk of HIV infection, defined as the absence of an identifiable risk factor/ behavior 9. Verbal assurances that adequate birth control measures are used not to conceive/father a child during the study and up to 3 months after the last vaccine injection 10. Women shall have a negative urinary pregnancy test 11. Be willing to practice safe sex for the duration of the study to avoid sexually transmitted infections including HIV. 12. Good health as determined by medical history, physical examination, clinical judgment and by key laboratory parameters as judged by the study physician. 1. At risk of HIV infection as mentioned above in the inclusion criteria 2. Active tuberculosis or other systemic infectious process elicited by review of systems, physical examination and laboratory detection (for example detection of Hepatitis B surface antigen, or active syphilis). 3. A history of immunodeficiency, chronic illness requiring continuous or frequent medical intervention 4. Autoimmune disease by history and physical examination. 5. Hives or recurrent hives and severe eczema 6. A history of psychiatric, medical (including traditional medicine) and/or substance abuse problems during the past 6 months that the investigator believes would adversely affect the volunteer's ability to participate in the trial. 7.
