abstract = {T-cell immunity is central for control of COVID-19,
particularly in patients incapable of mounting antibody
responses. CoVac-1 is a peptide-based T-cell activator
composed of SARS-CoV-2 epitopes with documented favorable
safety profile and efficacy in terms of SARS-CoV-2-specific
T-cell response. We here report a Phase I/II open-label
trial (NCT04954469) in 54 patients with congenital or
acquired B-cell deficiency receiving one subcutaneous
CoVac-1 dose. Immunogenicity in terms of CoVac-1-induced
T-cell responses and safety are the primary and secondary
endpoints, respectively. No serious or grade 4
CoVac-1-related adverse events have been observed. Expected
local granuloma formation has been observed in $94\%$ of
study subjects, whereas systemic reactogenicity has been
mild or absent. SARS-CoV-2-specific T-cell responses have
been induced in $86\%$ of patients and are directed to
multiple CoVac-1 peptides, not affected by any current
Omicron variants and mediated by multifunctional T-helper 1
CD4+ T cells. CoVac-1-induced T-cell responses have exceeded
those directed to the spike protein after mRNA-based
vaccination of B-cell deficient patients and immunocompetent
COVID-19 convalescents with and without seroconversion.
Overall, our data show that CoVac-1 induces broad and potent
T-cell responses in patients with B-cell/antibody deficiency
with a favorable safety profile, which warrants advancement
to pivotal Phase III safety and efficacy evaluation.
