About this trial

This is a Phase I/IIa, randomized, double-blind, placebo-controlled, dose-escalation clinical trial to test the candidate vaccine StreptInCor. The study will include four different doses (25 µg, 50 µg, 100 µg, and 200 µg) of StreptInCor produced under Good Manufacturing Practices (GMP) and formulated with aluminum hydroxide as the vaccine adjuvant. The adjuvant alone will be used as a placebo in this trial. Five groups, each consisting of twelve healthy adult volunteers, will randomly receive two doses of the vaccine or placebo with a 28-day interval, along with a booster dose six months after the initial vaccination

Trial outcomes

Primary outcomes

1

Safety outcome

• Safety outcome: The primary safety objective will be the absence of serious adverse events following immunization that have a reasonable causal relationship with the studied product in the StreptInCor and placebo groups;

Time frame
From enrollment to the end of treatment at six months
2

Immunogenicity outcome

Immunogenicity outcome: The primary immunogenicity outcome will be an increase of at least 4 times in IgG antibody levels against the StreptInCor peptide, 6 months after the last immunization.

Time frame
From enrollment to the end of treatment at six months
