Trial Summary

What is the purpose of this trial?This is an open-label study to examine the safety and immunogenicity of synthetic DNAs encoding NP-GT8 and IL-12 with or without a TLR-agonist-adjuvanted Env Trimer 4571 boost in adults without HIV. The primary hypothesis is that vaccination with a recombinant DNA vaccine encoding a germline-targeting epitope followed by a trimeric protein boost will be safe and immunogenic.

Eligibility Criteria

Adults aged 18-55, in good health with stable blood pressure and no history of severe allergies or chronic conditions that could affect the trial. Must not be pregnant, breastfeeding, or at high risk for HIV. Participants should agree to use birth control and avoid other clinical trials during this study.

Treatment Details

The trial is testing synthetic DNAs encoding NP-GT8 and IL-12 with/without TLR-agonist-adjuvanted Env Trimer 4571 boost in HIV-negative adults. It aims to see if these vaccines are safe and can stimulate an immune response.

Experimental Treatment

Group I: Group 3Experimental Treatment5 Interventions

a total of approximately 18 participants will receive 3 administrations of sD-NP-GT8 DNA at a dose of 1.6 mg, coformulated with IL-12 DNA at a dose of 0.4 mg at days 1, 29, and 85. These doses will be administered intradermally via EP of the skin on each upper arm. All participants in Group 3 will also receive 2 administrations of Trimer 4571 at a dose of 100 mcg adjuvanted with 5 mcg of 3M-052-AF + 500 mcg Alum via IM injections into the deltoid muscle at days 85 and 169

Group II: Group 2Experimental Treatment2 Interventions

a total of approximately 18 participants will receive 3 administrations of sD-NP-GT8 DNA at a dose of 1.6 mg, coformulated with IL-12 DNA at a dose of 0.4 mg at days 1, 29, and 85. Study products will be administered intradermally via EP of the skin on each upper arm

Group III: Group 1Experimental Treatment2 Interventions

a total of approximately 9 participants will receive 3 administrations of sD-NP-GT8 DNA at a dose of 0.4 mg, coformulated with IL-12 DNA at a dose of 0.1 mg at days 1, 29, and 85. Study products will be administered intradermally via EP of the skin on each upper arm
