A Study to Evaluate Safety and Immunogenicity of a COVID-19 Vaccine in People Living With HIV at Risk for SARS-CoV-2 (COVID-19) (COVID-19)

March 14, 2023 updated by: Novavax

A Phase 2, Randomized, Observer-Blinded Study to Evaluate the Safety and Immunogenicity of a SARS-CoV-2 Recombinant Spike Protein Nanoparticle Vaccine (SARS-CoV-2 rS) With Matrix-M™ Adjuvant in People Living With HIV

This is a Phase 2, randomized, observer-blinded study evaluating the safety and immunogenicity of SARS-CoV-2 with Matrix-M™ Adjuvant in people living with human immunodeficiency virus (HIV) (PLWH) and HIV- negative adults, seronegative to SARS-CoV-2 at baseline.

Detailed Description

The investigational product will be a monovalent Serum Institute of India (SII) SARS CoV-2 vaccine at a dose of 5 µg antigen adjuvanted with 50 µg Matrix-M (referred hereafter as NVX-CoV2373).

Approximately 270 PLWH, 18 to 65 years of age inclusive, will be enrolled into 3 groups and stratified at presentation based on the level of control of HIV infection. All PLWH will be baseline seronegative (for SARS-CoV-2) and have not received any authorized SARS-CoV-2 vaccines. PLWH will be randomly assigned 1:1:1 to receive NVX-CoV2373 in either a two dose regimen on Days 0 and 21 or Days 0 and 70 or a three-dose regimen on Days 0, 21, and 70. Randomization of PLWH will be stratified by level of control of HIV infection to distribute well controlled and less well controlled participants approximately evenly among the 3 PLWH treatment groups. Approximately 90 HIV negative participants, 18 to 65 years of age inclusive, will be randomly assigned 1:1 to receive NVX-CoV2373 in a two dose regimen on Days 0 and 21 or Days 0 and 70. All HIV negative participants will be baseline seronegative (for SARS-CoV-2) and have not received any authorized SARS-CoV-2 vaccines. Placebo (normal saline solution) will be administered to participants who receive a two-dose regimen of NVX-CoV2373 to maintain overall blinding.
