Brief Summary

Background: HIV stands for human immunodeficiency virus, which is the virus that causes AIDS. There is currently no licensed vaccine to prevent HIV infection. Researchers want to test a vaccine called Trimer 4571 for the first time. It was made at the National Institutes of Health (NIH) and contains no HIV. The vaccine is mixed with a substance called alum and injected in the arm. Alum is included to boost the body's immune response to the vaccine. It has been used in licensed vaccines for over 60 years and has been found to be safe. Objectives: To see if the vaccine Trimer 4571 is safe, well-tolerated, and to study immune responses to it. Eligibility: Healthy adults ages 18-50 years Design: Participants were screened with a physical exam and blood tests. They agreed to not become pregnant and to avoid behavior that would put them at high-risk for HIV infection during the study. Participants had about 15 study visits over about 9 months. The first 6 participants received a low dose of the vaccine mixed with alum. Once the low dose was deemed safe, 10 new participants were allocated to receive a higher dose. All participants were randomly assigned to get the vaccine by injection in a muscle or under the skin. All participants received a total of 3 vaccine injections over 20 weeks. Each visit where participants received the vaccine lasted about 5 hours. Participants were watched after each injection. Participants who were able to get pregnant would have a pregnancy test before each injection. Participants received a thermometer and recorded their temperature and symptoms every day for 1 week after each injection. The injection site was checked for redness, swelling, or bruising. At follow-up visits, participants had blood drawn and checked for health changes or problems. Follow up visits lasted about 1-2 hours.

Outcome Measures

Primary Outcomes (5)

  • Number of Participants Reporting Local Reactogenicity Signs and Symptoms For 7 Days After Each Product Administration

    Participants recorded the occurrence of solicited symptoms on a diary card for 7 days after each study product administration and reviewed the diary card with clinic staff at a follow up visit. Participants were counted once for each symptom at the worst severity if they indicated experiencing the symptom more than one time at any severity during the reporting period. The number reported for "Any Local Symptom" is the number of participants reporting any local symptom at the worst severity. Reactogenicity grading (Mild, Moderate, Severe) was done using the U.S. Department of Health and Human Services, National Institutes of Health, National Institute of Allergy and Infectious Diseases, Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1.

    7 days after study product administration, at approximately Week 1, Week 9 and Week 21

  • Number of Participants Reporting Systemic Reactogenicity Signs and Symptoms for 7 Days After Each Product Administration

    Participants recorded the occurrence of solicited symptoms on a diary card for 7 days after the study product administration and reviewed the diary card with clinic staff at a follow up visit. Participants were counted once for each symptom at the worst severity if they indicated experiencing the symptom more than one time at any severity during the reporting period. The number reported for "Any Systemic Symptom" is the number of participants reporting any systemic symptom at the worst severity. Reactogenicity grading (Mild, Moderate, Severe) was done using the U.S. Department of Health and Human Services, National Institutes of Health, National Institute of Allergy and Infectious Diseases, Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1.

    7 days after study product administration, at approximately Week 1, Week 9 and Week 21

  • Number of Participants With Abnormal Laboratory Measures of Safety

    Any abnormal laboratory results recorded as unsolicited adverse events (AEs) are summarized. Labs included hematology (hemoglobin, hematocrit, mean corpuscular volume (MCV), platelets, white blood cell (WBC), red blood cell (RBC), neutrophil, lymphocyte, monocyte, eosinophil and basophil counts) and chemistry (alanine aminotransferase (ALT) and creatinine). Complete blood count (CBC) with differential, creatine and ALT results were collected at screening, Day 0 prior to the first study product administration (baseline), and Weeks 1-2 after the 1st administration, Week 8 (2nd product administration), and Weeks 9-10 after the 2nd administration, Week 20 (3rd product administration), and Weeks 21-22 after the 3rd administration. Institutional laboratory normal ranges as well as the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1 were used.

    Through 40 weeks after the first study product administration

  • Number of Participants With One or More Unsolicited Non-Serious Adverse Events (AEs)

    Unsolicited AEs and attribution assessments were recorded in the study database from receipt of each study product administration through the visit scheduled at 28 days (or 4 weeks) after each study product administration. At other time periods greater than the 28-day (or 4-week) post product administration visit, only serious AEs (SAEs reported as a separate outcome and in the AE module), and new chronic medical conditions that required ongoing medical management were recorded through the last study visit. The relationship between an AE and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity. If a participant had several AEs and some were evaluated as related and some as unrelated to study product, the participant is counted once as having the related event.

    Through 28 days after each study product administration, up to Week 24

  • Number of Participants With Serious Adverse Events (SAEs)

    SAEs were recorded from receipt of the study product administration through the last expected study visit at Week 40. The relationship between a SAE and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity.

    Through 40 weeks after the first study product administration

Interventions

Trimer 4571 drug product is an investigational HIV vaccine which mimics the native HIV-1 envelope complex. This soluble HIV-1 envelope product consists of an HIV-1 envelope (Env) trimer variant, derived from clade A, strain BG505, with stabilizing mutations and engineered disulfide bonds, specifically recognized by broadly neutralizing antibodies and resists gp120 conformational change caused by CD4 binding.

Also known as: Trimer 4571
