Brief Summary:
The purpose of this study is to evaluate the vaccine efficacy (VE) of a heterologous vaccine regimen utilizing Ad26.Mos4.HIV and aluminum phosphate-adjuvanted Clade C gp140 and Mosaic gp140 for the prevention of HIV-1 infection in HIV-1 seronegative cis-gender men and transgender individuals having sex with cis-gender men and/or transgender individuals.

Condition or disease Intervention/treatment Phase
Healthy Biological: Ad26.Mos4.HIV Biological: Clade C and Mosaic gp140 HIV bivalent vaccine Biological: Placebo Phase 3

Detailed Description:
Human immunodeficiency virus type 1 (HIV-1) is a retrovirus that, if left untreated, can progress to acquired immunodeficiency syndrome (AIDS), a condition in which the immune system is severely compromised, leading to life-threatening conditions. Ad26.Mos4.HIV is a tetravalent vaccine composed of Ad26.Mos1.Gag-Pol, Ad26.Mos2.Gag-Pol, Ad26.Mos1.Env, and Ad26.Mos2S.Env. Clade C and Mosaic gp140 HIV bivalent vaccine contains: Clade C gp140, HIV-1 Env gp140 of Clade C, Mosaic gp140, HIV-1 Env gp140, and aluminum phosphate adjuvant. Evidences showed that a combination of vaccination with Ad26.Mos.HIV followed by Ad26.Mos.HIV together with Clade C gp140 protein in aluminum phosphate adjuvant led to highest level of protection observed so far with this vaccine concept. Study comprises of a screening period of 45 days, a 12-month vaccination period and a follow-up period of at least 18 months after fourth vaccination (until Month 30) in participants who remain HIV-1 negative or up to 6 months after diagnosis of HIV-1 infection in participants who become HIV-1 infected. Participants who completed their Month 30 visit will be followed for HIV infection, medically-attended adverse event (MAAEs) and serious adverse events until the end of study (Month 30). Primary analysis of vaccine efficacy will evaluate the number of HIV-1 infections in the vaccine group compared to number of HIV-1 infections in the placebo group between Month 7 and Month X (with 24<=X<=30) in per-protocol population.

Primary Outcome Measures :
  1. Vaccine Efficacy (VE) as Derived From Confirmed HIV-1 Infections Diagnosed Between the Month 7 and Month X (with 24 Less Than or Equal to [<=] X <= 30) Visits [ Time Frame: From Month 7 up to Month 30 ]
    Vaccine efficacy is defined as 1-cumulative incidence ratio (vaccine versus placebo) between Month 7 and Month X after first vaccination and is estimated by the transformation of the Nelson-Aalen estimator for the cumulative hazard function after enrollment in the per-protocol (PP) population. Here, month X will be between month 24 and month 30.


Secondary Outcome Measures :
  1. Number of Participants with Solicited Local and Systemic Adverse Events (AEs) [ Time Frame: 7 days after each vaccination on Months 0, 3, 6, and 12 ]
    Number of participants with local solicited adverse events will be evaluated. An adverse event is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product and does not necessarily have a causal relationship with the intervention, therefore it can be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not related to that medicinal product. Solicited local AEs include assessment of pain/tenderness, erythema and swelling. Solicited systemic AEs: fatigue, headache, nausea, myalgia, chills, arthralgia, and vomiting will be assessed.

  2. Number of Participants with Unsolicited Adverse Events [ Time Frame: 28 days after each vaccination on Months 0, 3, 6, and 12 ]
    Number of Participants with unsolicited AEs will be evaluated. Unsolicited adverse events are all adverse events for which the participant is specifically not questioned in the participant diary.

  3. Number of Participants with Medically-attended adverse events (MAAEs) [ Time Frame: Up to 43 Months (participants will be followed until the last participant reaches Month 30) ]
    Number of participants with MAAEs will be evaluated. MAAEs are defined as adverse events with medically attended visits including hospital, emergency room, urgent care clinic, or other visits to or from medical personnel for any reason.

  4. Number of Participants with Serious Adverse Events (SAEs) [ Time Frame: Up to 43 Months (participants will be followed until the last participant reaches Month 30) ]
    Number of participants with SAE will be evaluated. An SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above.

  5. Number of Participants who Discontinue from the Study or Vaccination due to Adverse Events [ Time Frame: Up to 43 Months (participants will be followed until the last participant reaches Month 30) ]
    Number of participants who discontinue from the study or vaccination due to AEs will be evaluated. Participants will be withdrawn from study vaccine administration due to unblinding due to safety reasons, Pregnancy, Confirmed HIV-1 infection, Any related adverse event, Worsening of health status or intercurrent illnesses that in the opinion of the investigator, Required discontinuation from study vaccine, Anaphylactic reaction following vaccination, Serious adverse event or other potentially life-threatening (Grade 4) event that is determined to be related to study vaccine, Chronic or recurrent use of systemic immunomodulators/suppressants, example, cancer chemotherapeutic agents (after discussion with the sponsor), Use of HIV-related monoclonal antibodies (mAbs).

  6. Vaccine Efficacy as Derived From Confirmed HIV-1 Infections Diagnosed at VE (0-X months) per Modified Intent-to-Treat (mITT) Population [ Time Frame: Month 0 (Day 1) up to Month 30 ]
    Vaccine efficacy is defined as 1-cumulative incidence ratio (vaccine versus placebo) between Month 0 and Month X after first vaccination and is estimated by the transformation of the Nelson-Aalen estimator for the cumulative hazard function per mITT populations. Here, month X will be between month 24 and month 30.

  7. Vaccine Efficacy as Derived From Confirmed HIV-1 Infections Diagnosed at VE (13-X months) per mITT Population [ Time Frame: Month 13 up to Month 30 ]
    Vaccine efficacy is defined as 1-cumulative incidence ratio (vaccine versus placebo) between Month 13 and Month X after first vaccination and is estimated by the transformation of the Nelson-Aalen estimator for the cumulative hazard function per mITT populations. Here, month X will be between month 24 and month 30.

  8. Frequency of HIV-1 Env-Specific Humoral Immune Responses as Determined by Clade C gp140 and Mos1 gp140 Specific ELISA [ Time Frame: Month 0 (Day 1) up to Month 30 ]
    Frequency of HIV-1 Env-specific humoral immune responses in PP population will be determined by Clade C gp140 and Mos1 gp140 specific enzyme-linked immunosorbent assay (ELISA).

  9. Frequency of HIV-1 Env-Specific Cellular Immune Responses as Determined by Clinical Potential T Cell Epitopes Envelope Peptide Enzyme-Linked Immunospot [ Time Frame: Month 0 (Day 1) up to Month 30 ]
