A Phase 1/2a Trial to Evaluate the Safety/Tolerability and Immunogenicity of Homologous Ad26 Mosaic Vector Regimens or Ad26 Mosaic and MVA Mosaic Heterologous Vector Regimens, With High-Dose, Low-Dose or no Clade C gp140 Protein Plus Adjuvant for HIV Prevention
In Brief
A Phase 2 clinical trial evaluating Ad26.Mos.HIV, MVA-Mosaic, and 3 other interventions for Healthy. Completed, enrolled 393 participants across 12 sites in 5 countries.
Detailed Summary
The purpose of this study is to assess the safety and tolerability of various regimens containing adenovirus serotype 26-Mosaic -Human Immunodeficiency Virus (Ad26.Mos.HIV), Modified Vaccinia Ankara (MVA)-Mosaic, and/or HIV type 1 Clade C glycoprotein 140 drug product (gp140 DP) components and to compare envelope binding antibody responses between the different vaccine regimens.
Study Details
Timeline
Interventions
Recombinant replication-deficient Ad26 vectored vaccine and consists of 3 Ad26 vectors, one containing a mosaic insert of envelop (Env) sequence, and 2 vectors containing mosaic inserts of Gag and Pol sequences (Ad26.Mos.1.Env + Ad26.Mos1.Gag-Pol + Ad26.Mos2.Gag-Pol). Total dose is 5\*10\^10 viral particle per 0.5 milliliter (mL) injection administered intramuscularly.
Recombinant live attenuated MVA virus-vectored vaccine that has been genetically engineered to express 2 mosaic Gag, Pol, and Env sequences (Mosaic 1 and Mosaic 2). Total dose is 10\^8 plaque-forming unit per 0.5 mL injection administered intramuscularly.
The gp140 DP vaccine containing 50 mcg of total protein, mixed with aluminum phosphate adjuvant (0.425 mg aluminum), per 0.5 mL injection administered intramuscularly.
The gp140 DP vaccine containing 250 mcg of total protein, mixed with aluminum phosphate adjuvant, per 0.5 mL injection administered intramuscularly.
Normal saline, 0.5 mL injection administered intramuscularly.
