Detailed Description:

This study will evaluate the preventive vaccine efficacy, safety, and tolerability of the ALVAC-HIV vaccine + Bivalent Subtype C gp120 protein adjuvanted with MF59 in HIV-seronegative South African adults over 24 months from enrollment.

Participants will be randomized to receive ALVAC-HIV (vCP2438), or placebo, by intramuscular injection at weeks 0 and 4; they will receive ALVAC-HIV (vCP2438) + Bivalent Subtype C gp120/MF59, or placebo, by IM injection at weeks 12, 24, and 52.

In addition to the vaccination visits, participants will attend study visits at weeks 26, 39, 54, 65, 78, 91, 104, 117, 130, 142, and 156. All study visits, including vaccination visits, will include HIV risk reduction counseling, a physical exam, and an interview/questionnaire. and pregnancy testing for participants capable of becoming pregnant. Select study visits will include a medical history review, physical exam, blood collection, urine collection, HIV testing, and pregnancy testing for participants capable of becoming pregnant.

As of February 3, 2020, vaccinations for this study were suspended. Participants have been asked to continue attending follow-up visits for 12 months after the last vaccination they received. Participants who become HIV infected will be followed for 6 months after diagnosis.

Outcome Measures

Primary Outcome Measures :

1. Incidence Rate of HIV-1 Infection Diagnosed After Enrollment (Concurrent With First Vaccination) Through 24 Months After Enrollment [ Time Frame: Measured through 24 months after first vaccination ]
   Vaccine efficacy was calculated as 1 minus the hazard ratio for HIV-1 infection, which was estimated using a sex-stratified Cox proportional-hazards (Cox PH) model and tested using a sex-stratified log-rank test. Vaccine efficacy was also measured using a ratio of cumulative incidences (CIR) of HIV-1 infection in the vaccine group as compared with the placebo group, which was calculated using Nelson-Aalen cumulative hazard estimates and tested using a Wald test.
2. Number of Participants Reporting Local Reactogenicity Signs and Symptoms: Pain and/or Tenderness [ Time Frame: Measured through 3 full days following each vaccination ]
   Graded according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.1 [July 2017]. The maximum grade observed for each symptom over the time frame is presented.
3. Number of Participants Reporting Local Reactogenicity Signs and Symptoms: Erythema and/or Induration [ Time Frame: Measured through 3 full days following each vaccination ]
   Graded according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.1 [July 2017]. The maximum grade observed for each symptom over the time frame is presented.
4. Number of Participants Reporting Systemic Reactogenicity Signs and Symptoms [ Time Frame: Measured through 3 full days following each vaccination ]
   Graded according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.1 [July 2017]. The maximum grade observed for each symptom over the time frame is presented.
5. Number of Participants Reporting Adverse Events (AEs), by Relationship to Study Product [ Time Frame: Measured through 30 days after each vaccination ]
   For participants reporting multiple AEs over the time frame, the maximum relationship is counted.
6. Number of Participants Reporting Adverse Events (AEs), by Severity Grade [ Time Frame: Measured through 30 days after each vaccination ]
   For participants reporting multiple AEs over the time frame, the maximum severity grade is counted.
7. Number of Participants Reporting Serious Adverse Events (SAEs) [ Time Frame: Measured through 12 months after last vaccination ]
   Measured as outlined in Version 2.0 (January 2010) of the Manual for Expedited Reporting of Adverse Events to DAIDS (DAIDS EAE Manual).
8. Number of Participants Reporting Adverse Events of Special Interest (AESIs) [ Time Frame: Measured through 12 months after last vaccination ]
   Adverse events of special interest (AESI) were described in Appendix J of the protocol. AESI for this protocol include but are not limited to potential immune-mediated diseases.
9. Number of Participants Reporting New Chronic Medical Conditions [ Time Frame: Measured through 12 months after last vaccination ]
   A new chronic medical condition is defined as a new onset or exacerbation of medical condition requiring 2 or more visits to a medical provider during a period of at least 30 days.
10. Number of Participants With Early Study Termination Associated With an AE or Reactogenicity [ Time Frame: Measured through study completion (through 6 months after confirmation of HIV-1 diagnosis for participants who acquired HIV and through 12 months after last vaccination for the rest) ]
    From the termination form, early study termination associated with an AE or reactogenicity reasons are tabulated by treatment group.
11. Number of Participants With Study Product Discontinuation Associated With an AE or Reactogenicity [ Time Frame: Measured through study completion (through 6 months after confirmation of HIV-1 diagnosis for participants who acquired HIV and through 12 months after last vaccination for the rest) ]

12. Incidence Rate of HIV-1 Infections Diagnosed Following Enrollment and Throughout All Participant Follow-Up [ Time Frame: Measured through 36 months after first vaccination ]
    Per the 23 January 2020 DSMB finding that monitoring boundaries for non-efficacy have been met, Primary outcome 1 has been superseded by this primary outcome. Vaccine efficacy was calculated as 1 minus the hazard ratio for HIV-1 infection, which was estimated using a sex-stratified Cox proportional-hazards (Cox PH) model and tested using a sex-stratified log-rank test. Vaccine efficacy was also measured using a ratio of cumulative incidences (CIR) of HIV-1 infection in the vaccine group as compared with the placebo group, which was calculated using Nelson-Aalen cumulative hazard estimates and tested using a Wald test.
