Evaluating the Safety and Immune Response to Three Different DNA HIV Vaccines Administered With a MVA-CMDR Boost Vaccine in Healthy, HIV-Uninfected Adults

Completed · Phase 1 · Has a placebo group

Conditions studied: HIV Infections

In brief

The purpose of this study is to evaluate the safety and immune response to three DNA vaccines and a MVA-CMDR vaccine that may boost the immune response to the DNA vaccines in healthy, HIV-uninfected adults.

You may qualify if…

• General and Demographic Criteria
• Access to a participating HIV Vaccine Trials Network (HVTN) clinical research site (CRS) and willingness to be followed for the planned duration of the study
• Ability and willingness to provide informed consent
• Assessment of understanding: participant demonstrates understanding of this study; completes a questionnaire prior to first vaccination with verbal demonstration of understanding of all questionnaire items answered incorrectly
• Willing to be contacted annually after completion of scheduled clinic visits for a total of 3 years for U.S. participants (5 years for participants in Switzerland) following initial study injection
• Agrees not to enroll in another study of an investigational research agent
• Good general health as shown by medical history, physical exam, and screening laboratory tests
• HIV-Related Criteria
• Willingness to receive HIV test results
• Willingness to discuss HIV infection risks and amenable to HIV risk reduction counseling
• Assessed by the clinic staff as being at "low risk" for HIV infection and committed to maintaining behavior consistent with low risk of HIV exposure through the last required protocol clinic visit
• Laboratory Inclusion Values
• Hemogram/Complete Blood Count (CBC)
• Hemoglobin greater than or equal to 12.5 g/dL for participants who were born female, greater than or equal to 13.5 g/dL for participants who were born male
• White blood cell count equal to 3,300 to 12,000 cells/mm\^3
• Total lymphocyte count greater than or equal to 800 cells/mm\^3
• Remaining differential either within institutional normal range or with site physician approval
• Platelets equal to 125,000 to 550,000/mm\^3
• Chemistry
• Chemistry panel: alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase less than 1.25 times the institutional upper limit of normal; creatinine less than or equal to the institutional upper limit of normal
• Cardiac Troponin T or I (cTnT or cTnI) does not exceed the institutional upper limit of normal
• Virology
• Negative HIV-1 and -2 blood test: U.S. participants must have a negative Food and Drug Administration (FDA)-approved enzyme immunoassay (EIA). Non-U.S. site may use locally available assays that have been approved by HVTN Laboratory Operations.
• Negative hepatitis B surface antigen (HBsAg)
• Negative anti-hepatitis C virus antibodies (anti-HCV), or negative HCV polymerase chain reaction (PCR) if the anti-HCV is positive

You may not qualify if…

• General
• Blood products received within 120 days before first vaccination
• Investigational research agents received within 30 days before first vaccination
• Body mass index (BMI) greater than or equal to 40
• Intent to participate in another study of an investigational research agent during the planned duration of the HVTN 106 study
• Pregnant or breastfeeding
• Vaccines and Other Injections
• Smallpox vaccine received within the last 5 years
• HIV vaccine(s) received in a prior HIV vaccine trial. For participants who have received control/placebo in an HIV vaccine trial, the HVTN 106 Protocol Safety Review Team (PSRT) will determine eligibility on a case-by-case basis and the identity of the study control/placebo must be obtained.
• Non-HIV experimental vaccine(s) received within the last 5 years in a prior vaccine trial. Exceptions may be made for vaccines that have subsequently undergone licensure by the FDA. For participants who have received control/placebo in an experimental vaccine trial, the HVTN 106 PSRT will determine eligibility on a case-by-case basis. For participants who have received an experimental vaccine(s) more than 5 years ago, eligibility for enrollment will be determined by the HVTN 106 PSRT on a case-by-case basis.
• Live attenuated vaccines other than influenza vaccine received within 30 days before first vaccination or scheduled within 14 days after injection (e.g., measles, mumps, and rubella [MMR]; oral polio vaccine [OPV]; varicella; yellow fever)
• Influenza vaccine or any vaccines that are not live attenuated vaccines and were received within 14 days prior to first vaccination (e.g., tetanus, pneumococcal, hepatitis A or B)
• Allergy treatment with antigen injections within 30 days before first vaccination or that are scheduled within 14 days after first vaccination
• Immune System
• Immunosuppressive medications received within 168 days before first vaccination. (Not excluded: [1] corticosteroid nasal spray; [2] inhaled corticosteroids; [3] topical corticosteroids for mild, uncomplicated dermatitis; or [4] a single course of oral/parenteral corticosteroids at doses less than 2 mg/kg/day and length of therapy less than 11 days with completion at least 30 days prior to enrollment
• Serious adverse reactions to vaccines or to vaccine components such as neomycin or streptomycin, including anaphylaxis and related symptoms such as hives, respiratory difficulty, angioedema, and/or abdominal pain. (Not excluded: a participant who had a nonanaphylactic adverse reaction to pertussis vaccine as a child)
• Immunoglobulin received within 60 days before first vaccination
• Autoimmune disease
• Immunodeficiency
• Hypersensitivity to eggs and/or egg products
• Clinically Significant Medical Conditions
• Untreated or incompletely treated syphilis infection
• Clinically significant medical condition, physical examination findings, clinically significant abnormal laboratory results, or past medical history with clinically significant implications for current health. More information on this criterion can be found in the protocol.
• Any medical, psychiatric, occupational, or other condition that, in the judgment of the investigator, would interfere with, or serve as a contraindication to, protocol adherence, assessment of safety or reactogenicity, or a participant's ability to give informed consent
• Psychiatric condition that precludes compliance with the protocol. Specifically excluded are persons with psychoses within the past 3 years, ongoing risk for suicide, or history of suicide attempt or gesture within the past 3 years.
