About this trial

The study aims to investigate the safety and immunogenicity of one dose vs two doses of a T-cell priming next-generation vaccine against Coronavirus disease.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Healthy volunteers aged 18 to 75 years on the day of inclusion

Participant signed informed consent

Residing in Philippines.

A participant can be included providing COVID-19 polymerase chain reaction (PCR) test is negative at screening.

Disqualifiers

Participant is pregnant, lactating, or of childbearing potential

Participation in the 6 months preceding the first trial vaccination or planned participation during the present trial period in another clinical trial investigating a vaccine, drug, medical device, or medical procedure

Receipt of any vaccination against COVID-19 less than 6 months prior to participation in study.

Receipt of any vaccine in the three months preceding the first trial vaccination or planned receipt of any vaccine in the 6 months following last trial vaccination.

Trial design

Design model

Parallel

Treatments tested in this trial

  • PepGNP-COVID19 (One vaccination)

    Biological/Vaccine

    One dose with 7.5 nmol total peptide/dose with 47.8ug gold base particle in 50 µl WFI

  • Water for injection (One vaccination)

    Other intervention

    Water For Injection (WFI): (sodium chloride, a 0.9% solution for the preparation of dosage forms for injections) 50 µl per dose

  • PepGNP-COVID19 (Two vaccinations)

    Biological/Vaccine

    Two vaccinations with 7.5 nmol total peptide/dose with 47.8ug gold base particle in 50 µl WFI

  • Water for injection (Two vaccinations)

    Other intervention

    Water For Injection (WFI): (sodium chloride, a 0.9% solution for the preparation of dosage forms for injections) 50 µl per dose

Trial outcomes

Primary outcomes

1

To assess the safety, tolerability and reactogenicity of the vaccine

Occurrence of solicited local reactogenicity signs and symptoms up to 7 days after each injection. Occurrence of solicited systemic reactogenicity signs and symptoms up to 14 days after each injection. Occurrence of unsolicited adverse events, serious adverse events (SAEs), and adverse events of special interest (AESI) up to 6 months following first vaccination or End Of Study (EOS), whichever is later.

Time frame
6 months following first vaccination or End Of Study (EOS), whichever is later

Secondary outcomes

1

Assess the cellular immunogenicity of the vaccine candidate

Proportion of participants with T cells specific to PepGNP-COVID19 vaccine, and Proportion of subjects with activated cellular immunity cells via assessment of peptide-specific T cell response performed by cytometry, using dextramer staining and, by measuring activation markers upon stimulation with peptides

Time frame
180 days following first vaccination
2

Assess the humoral immunogenicity of the vaccine candidate

For individuals seronegative at enrolment - Proportion of participants becoming seropositive (antibodies against SARS-CoV-2 as determined by Enzyme-linked Immunosorbent Assay (ELISA)), and For individuals seropositive at enrolment - Fold change in anti-SARS-CoV-2 antibodies as determined by Enzyme-linked Immunosorbent Assay (ELISA)

Time frame
180 days following first vaccination
