About this study

Official title: Phase 2b, Randomized, Placebo-Controlled Test-of-Concept Trial to Evaluate the Safety and Efficacy of a Multiclade HIV-1 DNA Plasmid Vaccine Followed by a Multiclade HIV-1 Recombinant Adenoviral Vector Vaccine in HIV-Uninfected, Adenovirus Type 5 Neutralizing Antibody Negative, Circumcised Men and Male-to-Female (MTF) Transgender Persons, Who Have Sex With Men

The purpose of this study is to determine the safety and efficacy of a VRC DNA/rAd5 vaccine regimen in healthy, circumcised men and male-to-female (MTF) transgender persons who have sex with men.

NOTES:

As of April 2013, all vaccinations in this study have been stopped.

As of June 2017, this study has been closed.

Read the detailed description

In 2007, the Joint United Nations Programme on HIV/AIDS estimated that 33.2 million people were living with HIV/AIDS globally. The U.S. HIV prevalence data reported in October 2008 by the Centers for Disease Control and Prevention estimate that 1.1 million adults and adolescents were living with diagnosed or undiagnosed HIV infection in the United States at the end of 2006. Nearly half of all U.S. HIV infections (48.1%) were found in men who have sex with men (MSM). Given the difficulty of maintaining behaviors that prevent HIV transmission over a lifetime and the occurrence of nonconsensual sex, the need for a safe and effective vaccine is clear. The primary purpose of this study is to determine the safety and efficacy of a VRC DNA/rAd5 vaccine regimen in healthy, at-risk, circumcised men and MTF transgender persons who have sex with men.

Participants will be randomly assigned to one of two arms. Participants in Arm 1 will receive a recombinant DNA plasmid vaccine injection at study entry and on Days 28 and 56, followed by a recombinant adenoviral serotype vector vaccine injection on Day 168. Participants in Arm 2 will receive placebo injections at study entry and on Days 28, 56, and 168.

Participants who do not become HIV infected will be actively followed for a minimum of 24 months and will continue to be followed by the study for long-term safety surveillance for a total of 5 years following enrollment. Participants will be contacted annually during the period of long-term safety surveillance.

Participants who are found to be HIV infected prior to receiving their first injection or who receive their first injection but were HIV infected prior to study start will be followed on a modified schedule.

Participants who become HIV infected will be followed for 6 months post-diagnosis.

At most study visits, participants will undergo a physical exam and blood draw.

NOTES:

As of April 2013, all vaccinations in this study have been stopped. Participants have been notified of whether they received the study vaccines or placebo. Participants diagnosed with HIV infection will attend study visits for 6 months for health monitoring. Participants who are not diagnosed with HIV infection will attend planned study visits for 24 months and will be followed by the study clinic at least annually for a total of 5 years following study enrollment.

As of June 2017, this study has been closed. Therefore, to avoid further burden on study participants, further participant follow-up for the study is suspended.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Participant Dropout Through Month 48

    For participants remaining uninfected, dropout is assessed only for primary follow-up, i.e. clinic visits. Protocol versions 4 and earlier included 24 months of primary follow-up, and versions 5 and later included 48 months. Participants may terminate early after completing primary follow-up, and participants who were found to be HIV-1 infected are analyzed as non-dropouts, so the number of dropouts and number of early terminations need not match.

    Measured: Enrollment through Month 48 visit

  2. Participant Dropout Prior to Unblinding

    The trial was unblinded on April 23, 2013, and the protocol was in version 4 at the time.

    For participants remaining uninfected, dropout is assessed only for primary follow-up, i.e. clinic visits. Protocol versions 4 and earlier included 24 months of primary follow-up, and versions 5 and later included 48 months. Participants may terminate early after completing primary follow-up, and participants who were found to be HIV-1 infected are analyzed as non-dropouts, so the number of dropouts and number of early terminations need not match.

    Measured: Enrollment until the date of dropout, through April 22, 2013 (up to Month 24 visit)

  3. Participant Dropout After Unblinding

    The trial was unblinded on April 23, 2013, and the protocol was in version 4 at the time.

    For participants remaining uninfected, dropout is assessed only for primary follow-up, i.e. clinic visits. Protocol versions 4 and earlier included 24 months of primary follow-up, and versions 5 and later included 48 months. Participants may terminate early after completing primary follow-up, and participants who were found to be HIV-1 infected are analyzed as non-dropouts, so the number of dropouts and number of early terminations need not match.

    Measured: April 23, 2013 through trial closure (up to Month 48 visit)

  4. HIV-1 Infections Diagnosed After Day 0 Including All Available Follow-up Through the Maximum Month 48 Visit

    For time-to-event analysis, an event is defined as HIV-1 infection and participants are censored if they dropped out early or completed the trial. HIV-1 diagnosis date is defined as the date of the earliest specimen collection yielding a positive HIV test. Participants remaining uninfected were censored at the latest specimen collection with a negative HIV-1 test.

    Measured: Enrollment through Month 48 visit

  5. HIV-1 Infections Diagnosed After Day 0 Through the Month 24 Visit

    For time-to-event analysis, an event is defined as HIV-1 infection and participants remaining uninfected through the month 24 visit were censored. HIV-1 diagnosis date is defined as the date of the earliest specimen collection at or prior to month 24 which yielded a positive HIV test. Participants remaining uninfected through the month 24 visit were censored at the latest specimen collection with a negative HIV-1 test at or prior to the month 24 visit.

    Measured: Enrollment through Month 24 visit

  6. Number of Participants Experiencing Local Reactogenicity: Pain and/or Tenderness

    For each sign or symptom, we define the maximum observed grade for each participant over all vaccinations and post-vaccination assessments. Local and systemic signs and symptoms are assessed and graded based on The Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Version 1.0, December, 2004 (Clarification dated August 2009). Local reactogenicity parameters are pain, tenderness, erythema, and induration. We present the maximum grade for pain and/or tenderness, and erythema and/or induration.

    Measured: Through 3 days post each study vaccination, and to resolution for events present at the third day post vaccination

  7. Number of Participants Experiencing Local Reactogenicity: Erythema and/or Induration

    For each sign or symptom, we define the maximum observed grade for each participant over all vaccinations and post-vaccination assessments. Local and systemic signs and symptoms are assessed and graded based on The Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Version 1.0, December, 2004 (Clarification dated August 2009). Local reactogenicity parameters are pain, tenderness, erythema, and induration. We present the maximum grade for pain and/or tenderness, and erythema and/or induration.

    Measured: Through 3 days post each study vaccination, and to resolution for events present at the third day post vaccination

  8. Number of Participants Experiencing Systemic Reactogenicity

    For each sign or symptom, we define the maximum observed grade for each participant over all vaccinations and post-vaccination assessments. Local and systemic signs and symptoms are assessed and graded based on The Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Version 1.0, December, 2004 (Clarification dated August 2009). Systemic reactogenicity parameters are malaise/fatigue, myalgia, headache, nausea, vomiting, chills, and arthralgia. We present the maximum grade calculated over these parameters.

    Measured: Through 3 days post each study vaccination, and to resolution for events present at the third day post vaccination

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 15 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 27 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Participant Dropout Through Month 48 (time frame: Enrollment through Month 48 visit). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00865566, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2021.
