A Phase 1b Randomized, Double-blind, Placebo-controlled Clinical Trial to Evaluate the Safety and Immunogenicity of the IHV01 Protein Vaccine Primed and Co-administered With HIV DNA CON-S Env Vaccine in Healthy, HIV-1-Uninfected Adult Participants
調査の概要
詳細な説明
This study will evaluate the safety and immunogenicity of the IHV01 protein vaccine primed and co-administered with HIV DNA CON-S env vaccine in healthy, HIV-1-uninfected adults.
Participants will be randomly assigned to two groups. Participants in Group 1 will receive 4 mg of DNA CON-S env at Months 0 and 1. They will receive 4 mg of DNA CON-S env and 150 mcg of IHV01 at Months 3 and 6. Participants in Group 2 will receive placebo at Months 0, 1, 3, and 6.
Study visits will occur at Day 0 (study entry), Week 2, and Months 1, 1.5, 3, 3.5, 6, 6 + 1 week, 6.5, and 12. Visits may include physical examinations, medical history, injection of study product, blood and urine collection, pregnancy testing, HIV testing, risk reduction counseling, and questionnaires.

- Intrauterine device (IUD),
- Hormonal contraception, or
- Any other contraceptive method approved by the HVTN 125 Protocol Safety Review Team (PSRT)

- Or not be of reproductive potential, such as having reached menopause (no menses for 1 year) or having undergone hysterectomy, bilateral oophorectomy, or tubal ligation;
- Or be sexually abstinent.
- Volunteers who were born female must also agree not to seek pregnancy through alternative methods, such as artificial insemination or in vitro fertilization until after the last required protocol clinic visit
Exclusion Criteria:
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; or BMI greater than or equal to 35 with 2 or more of the following: age greater than 45, systolic blood pressure greater than 140 mm Hg, diastolic blood pressure greater than 90 mm Hg, current smoker, known hyperlipidemia
- Intent to participate in another study of an investigational research agent or any other study that requires non-HVTN HIV antibody testing during the planned duration of the HVTN 125 study
- Pregnant or breastfeeding
- Active duty and reserve US military personnel
Vaccines and other Injections
- HIV vaccine(s) received in a prior HIV vaccine trial. For volunteers who have received control/placebo in an HIV vaccine trial, the HVTN 125 PSRT will determine eligibility on a case-by-case basis.
- Previous receipt of monoclonal antibodies (mAbs), whether licensed or investigational; the HVTN 125 PSRT will determine eligibility on a case-by-case basis.
- Non-HIV experimental vaccine(s) received within the last 5 years in a prior vaccine trial. Exceptions may be made by the HVTN 125 PSRT for vaccines that have subsequently undergone licensure by the FDA. For volunteers who have received control/placebo in an experimental vaccine trial, the HVTN 125 PSRT will determine eligibility on a case-by-case basis. For volunteers who have received an experimental vaccine(s) greater than 5 years ago, eligibility for enrollment will be determined by the HVTN 125 PSRT on a case-by-case basis.
- Live attenuated vaccines received within 30 days before first vaccination or scheduled within 14 days after injection (eg, measles, mumps, and rubella [MMR]; oral polio vaccine [OPV]; varicella; yellow fever)
- Any vaccines that are not live attenuated vaccines and were received within 14 days prior to first vaccination (eg, tetanus, pneumococcal, Hepatitis A or B)

- A process that would affect the immune response,
- A process that would require medication that affects the immune response,
- Any contraindication to repeated injections or blood draws,
- A condition that requires active medical intervention or monitoring to avert grave danger to the volunteer's health or well-being during the study period,
- A condition or process for which signs or symptoms could be confused with reactions to vaccine, or
- Any condition specifically listed among the exclusion criteria below.

- Thyroidectomy, or thyroid disease requiring medication during the last 12 months
Hypertension:
- If a person has been found to have elevated blood pressure or hypertension during screening or previously, exclude for blood pressure that is not well controlled. Well-controlled blood pressure is defined as consistently less than or equal to 140 mm Hg systolic and less than or equal to 90 mm Hg diastolic, with or without medication, with only isolated, brief instances of higher readings, which must be less than or equal to 150 mm Hg systolic and less than or equal to 100 mm Hg diastolic. For these volunteers, blood pressure must be less than or equal to 140 mm Hg systolic and less than or equal to 90 mm Hg diastolic at enrollment.
- If a person has NOT been found to have elevated blood pressure or hypertension during screening or previously, exclude for systolic blood pressure greater than or equal to 150 mm Hg at enrollment or diastolic blood pressure greater than or equal to 100 mm Hg at enrollment.
- Bleeding disorder diagnosed by a doctor (eg, factor deficiency, coagulopathy, or platelet disorder requiring special precautions)
