A Clinical Trial in Healthy, HIV-1-Uninfected Adult Participants to Compare the Safety, Tolerability and Immunogenicity of CH505TF gp120 Produced From Stably Transfected Cells to CH505TF gp120 Produced From Transiently Transfected Cells
Completed · Phase 1
Conditions studied: HIV Infections
In brief
The purpose of this study is to compare the safety, tolerability, and immunogenicity of CH505TF gp120 produced from stably transfected cells to CH505TF gp120 produced from transiently transfected cells in healthy, HIV-1-uninfected adult participants.

Who can join
Age: 18 and older, up to 50. Sex: any. Healthy volunteers: accepted.
You may qualify if…
- General and Demographic Criteria
- Age of 18 to 50 years
- 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: volunteer 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 in person or by phone, text message, or e-mail 6 months after completion of the scheduled clinic visits
- Agrees not to enroll in another study of an investigational research agent before the last required protocol clinic visit
- 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. (see study protocol)
- Laboratory Inclusion Values
- Hemogram/Complete blood count (CBC)
- Hemoglobin greater than or equal to 11.0 g/dL for volunteers who were assigned female sex at birth, greater than or equal to 13.0 g/dL for volunteers who were assigned male sex at birth. For transgender participants who have been on hormone therapy for more than 6 consecutive months, determine hemoglobin eligibility based on the gender with which they identify (ie, a transgender female who has been on hormone therapy for more than 6 consecutive months should be assessed for eligibility using the hemoglobin parameters for persons assigned female sex at birth).
- 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 institutional upper limit of normal.
- Virology
- Negative HIV-1 and -2 blood test: US volunteers must have a negative US Food and Drug Administration (FDA)-approved enzyme immunoassay (EIA).
- 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; 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 123 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 123 PSRT will determine eligibility on a case-by-case basis.
- Previous receipt of monoclonal antibodies (mAbs), whether licensed or investigational; the HVTN 123 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 123 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 123 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 123 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)
- 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 exclusionary: [1] corticosteroid nasal spray; [2] inhaled corticosteroids; [3] topical corticosteroids for mild, uncomplicated dermatitis; or [4] a single course of oral/parenteral prednisone or equivalent at doses less than or equal to 60 mg/day and length of therapy less than 11 days with completion at least 30 days prior to enrollment)
- Serious adverse reactions to vaccines including history of anaphylaxis and related symptoms such as hives, respiratory difficulty, angioedema, and/or abdominal pain. (Not excluded from participation: a volunteer who had a nonanaphylactic adverse reaction to pertussis vaccine as a child.)
- Immunoglobulin received within 60 days before first vaccination
- Autoimmune disease
- Immunodeficiency
- Clinically significant medical conditions
- Clinically significant medical condition, physical examination findings, clinically significant abnormal laboratory results, or past medical history with clinically significant implications for current health. A clinically significant condition or process includes but is not limited to:
- 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,
