Brief summary
This is a Phase 1 study to evaluate the safety, tolerability, pharmacokinetics and anti-viral efficacy of the PGT121 monoclonal antibody for HIV prevention and therapy.
Detailed description
This is a Phase 1 study to evaluate the safety, tolerability, pharmacokinetics and anti-viral efficacy of the PGT121 monoclonal antibody for HIV prevention and therapy. PGT121 mAb is a recombinant human IgG1 monoclonal antibody that targets a V3 glycan-dependent epitope region of the HIV envelope protein. PGT121 mAb was chosen for this study because it is potent, neutralizes a wide array of HIV viruses, and can prevent and treat simian-human immunodeficiency virus (SHIV) in rhesus monkeys.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of participants with PGT121 mAb reactogenicity, related AEs and SAEs | 6 Months post infusion | The investigators will measure the following endpoints to evaluate the safety and tolerability of PGT121 mAb in HIV-uninfected and HIV-infected adults: 1. Proportion of participants with moderate or greater reactogenicity (e.g., solicited adverse events) for 3 days following IV infusion of PGT121 mAb. 2. Proportion of participants with moderate or greater and/or PGT121 mAb-related unsolicited adverse events (AEs), including safety laboratory (biochemical, hematological) parameters, following IV infusion of PGT121 mAb for the first 56 days post administration of Investigational Product. 3. Proportion of participants with PGT121 mAb-related serious adverse events (SAEs) throughout the study period. |
