Safety and Immunogenicity of TBC-M4, a MVA HIV Vaccine Alone or in a Prime-Boost Regimen With ADVAX DNA HIV Vaccine
This study has been completed.
Information provided by (Responsible Party):
International AIDS Vaccine Initiative
First received: May 13, 2009

Last verified: February 2013
This trial will study a prime-boost vaccine approach designed mainly to induce cell-mediated immune (CTL) responses.
Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
||Phase I Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Safety and Immunogenicity of TBC-M4 (MVA Based HIV Vaccine) Alone or in a Prime-Boost Regimen With ADVAX, DNA HIV Vaccine
Primary Outcome Measures:
Secondary Outcome Measures:
- Immunogenicity of TBM-M4 alone or in a prime-boost regimen with ADVAX [ Time Frame: 12 months ] [ Designated as safety issue: No ]
| Study Start Date:
| Study Completion Date:
| Primary Completion Date:
||April 2010 (Final data collection date for primary outcome measure)
Active Comparator: Group A
ADVAX at 0,1 and 2 months followed by TBC-M4 at 6 months
Number of volunteers: 12
Receive 4mg ADVAX at Months 0, 1, and 2 (Biojector), and receive boost of 5x10^7 pfu TBC-M4 (IM)
Active Comparator: Group B
TBC-M4 at 0,1,6 months
Number of volunteers: 12
Receive 5x10^7 pfu TBC-M4 (IM) at Months 0, 1, and 6.
Placebo Comparator: Placebo
Both Groups A and B will have 4 volunteers each (8 total) that will receive a placebo.
Group A (n=4) will receive the ADVAX placebo (formulation buffer) via Biojector.
Group B (n=4) will receive the TBC-M4 placebo (formulation buffer) via IM.
Two vaccine candidates will be used in two different prime-boost regimens: ADVAX (DNA) + TBC-M4 (MVA) and TBC-M4 (MVA) alone. Both these vaccines have already been tested in humans and both were found to be well tolerated and immunogenic. Approximately 32 volunteers (24 vaccine /8 placebo recipients) will be included in the study.

All female volunteers must be willing to undergo urine pregnancy tests at time points as indicated in the Schedule of Procedures (Appendix A);
- If sexually active male, willing to use an effective method of contraception (such as condoms, anatomical sterility) from the day of enrolment until at least 4 months after the last vaccination;
- Willing to forgo donations of blood, sperm, eggs, bone marrow or organs during the study.
- Confirmed HIV-1 or HIV-2 infection;
High-risk behaviour for HIV infection which is defined as (Within 6 months before vaccination, the volunteer has):
- Had unprotected vaginal or anal sex with a known HIV infected person or a casual partner (i.e., no continuing established relationship)
- Engaged in sex work for money or drugs
- Substance abuse/use injection drugs
- Acquired a sexually transmitted disease (STD) (e.g., gonorrhoea, chlamydia, syphilis, Trichomonas vaginalis, and symptomatic herpes genitalis)
- Having a high-risk partner either currently or within the previous 6 months
- Any clinically significant abnormality on history or examination including history of immunodeficiency or autoimmune disease; use of systemic corticosteroids, immunosuppressive, antiviral, anticancer, or other medications considered significant by the investigator within the previous 6 months; (Note: use of inhaled steroids for asthma and 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 investigator would make the volunteer unsuitable for the study;
Any of the following abnormal laboratory parameters listed below:
- Confirmed diagnosis of hepatitis B (HBsAg), hepatitis C (HCV antibodies), or active syphilis;
- If female, pregnant or planning a pregnancy within 4 months after last vaccination; or lactating;
- Receipt of live attenuated vaccine within the previous 60 days (live attenuated flu vaccine within 14 days) or planned receipt within 60 days after vaccination with Investigational Product or receipt of other vaccine within the previous 14 days or planned receipt within 14 days after vaccination with Investigational Product;
- Receipt of blood transfusion or blood products within the previous 6 months.
- Participation in another clinical study of an investigational product currently, within the previous 3 months or expected participation during this study;
- Receipt of another investigational HIV vaccine in the last 6 years (note: receipt of an HIV vaccine placebo will not exclude a subject from participation if documentation is available to the study site and the IAVI Medical Monitor gives approval);
- History of severe local or systemic reactogenicity to vaccines or history of severe allergic reactions;
- Major psychiatric illness including any history of schizophrenia or severe psychosis, bipolar disorder requiring therapy, suicidal attempt or ideation in the previous 3 years;
