Official title
Phase 1 Dose Ranging Study to Assess the Safety, Reactogenicity, and Immunogenicity of PepGNP-COVID19, a Synthetic Nanoparticle-based, T Cell Priming Peptide Vaccine Against SARS-CoV-2 As a Booster Dose
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This Phase 1 clinical trial will evaluate the safety, reactogenicity, and immunogenicity of PepGNP-COVID19, a synthetic nanoparticle-based, T cell-priming peptide vaccine against SARS-CoV-2, when administered as a booster dose in healthy adults. PepGNP-COVID19 is designed to induce broad and durable T cell-mediated immune responses by delivering conserved SARS-CoV-2 peptides covalently bound to carbohydrate-coated gold nanoparticles, with the goal of enhancing tissue-resident cytotoxic T lymphocytes in the respiratory tract and reducing the need for frequent antigen updates. This randomized, participant-blinded, dose-ranging, multi-site trial will enroll 60 healthy adults aged 18-64 years, with a target of 8 of 20 participants in each cohort being \> / = 50 years of age. Participants will receive a single intradermal injection of PepGNP-COVID19 at one of three dosage levels (0.83 nmol, 2.5 nmol, or 7.5 nmol in a volume of 0.05 mL). The primary objective is to evaluate the safety, reactogenicity, and tolerability of a single intradermal dose of PepGNP-COVID19 at three dosage levels in previously vaccinated healthy adults.
