Description of intervention(s) / exposure
This is a Phase 1, randomized, double-blind, active controlled, staggered, dose-escalation study, consisting of 2 cohorts to evaluate the safety, tolerability and immunogenicity of an intramuscular injection COVID-19 mRNA vaccine in healthy subjects who had previously received either two or three doses of the approved/authorized mRNA COVID-19 vaccine (Moderna). The study will consist of 2 cohorts (1 cohort per dose level). Each cohort will include 30 subjects for a total of 60 subjects.

A staggered dosing schedule will be used for dosing and will include 6 sentinel subjects in each cohort. Initially, 2 sentinels will receive IN002.5.1 and 1 will receive Moderna vaccine and the remaining sentinels will be vaccinated 3 days later in a 2:1 ratio (2 receiving IN002.5.1 and 1 receiving active control vaccine). In Cohort 1, the remaining 24 subjects will be dosed at least 7 days later, following review of sentinels’ safety and tolerability data through e-mail by a Safety Review Committee (SRC).Based on the SRC’s recommendations, the study will progress towards the vaccination of the remaining subjects in that cohort.

Based on the SRC’s recommendations, the study will progress towards the vaccination of the remaining subjects in that cohort, as well as subjects in the subsequently planned cohort.
The planned dose range is anticipated to be as follows:
• Cohort 1: single dose of 30 µg administered on Day 1 (formulation IN002.5.1) or 50 µg dose of active control vaccine.
• Cohort 2: single dose of 60 µg administered on Day 1 (formulation IN002.5.1) or 50 µg dose of active control vaccine.

The SRC will review the safety and tolerability data for the 24 subjects in Cohort 1 for up to 15 days through a formal meeting, in order to make decisions whether to continue vaccination of the remaining subjects in Cohort 2. The decision can be to escalate to the next dose level, decrease the next dose level, repeat a dose level, or to not evaluate any additional dose.

The pharmacist at site will be unblinded and will prepare the study drug. The trained nurse will perform administration. The procedure will observed and recorded by a member of study team.

Outcomes
Primary outcome [1] 332866 0
To evaluate the safety and tolerability of IN002.5.1 as a booster vaccine following IM administration in healthy subjects >= 18 years of age by assessing adverse event (AE) percentage of the booster vaccine.
Subjects will be monitored throughout the study by the clinical staff for AEs. An AE can be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of the investigational product, whether or not considered related to the investigational product.
A diary will be provided to subject to record local reactions, daily temperatures and other adverse event. The diary will be reviewed by the Investigator and the clinicians during the study. Meanwhile adequate medical surveillance will be assured during the confinement period and the Investigator or designee will be available on call at all times. If necessary, the Investigator or designee at the clinical site or a healthcare professional in a nearby hospital will administer treatment for any AE(s).
Timepoint [1] 332866 0
1. The occurrence of immediate AEs (time frame: 30 minutes after administration on Day 1); 2. Solicited local AE (time frame: 14 days after administration); 3. Solicited systemic AE (time frame: 14 days after administration); 4. Unsolicited AEs (time frame: 28 days after administration); 5. Serious Adverse Events (SAEs) (time frame: 6 months after administration); 6. Adverse events of special interest (AESIs) (time frame: 6 months after administration).
Primary outcome [2] 332867 0
To evaluate the immunogenicity of IN002.5.1 as a booster vaccine following IM administration in healthy subjects >= 18 years of age by assessing humoral response, using blood sample.
Timepoint [2] 332867 0
Humoral response on Day 29 after administration;
Primary outcome [3] 333015 0
To evaluate the immunogenicity of IN002.5.1 as a booster vaccine following IM administration in healthy subjects >= 18 years of age by assessing cell-mediated immunogenicity (CMI) response, using blood sample.
Timepoint [3] 333015 0
Cell-mediated immunogenicity (CMI) response in the specific cellular immunogenicity subgroup at Day 8, Day 29 after administration.
Secondary outcome [1] 414899 0
To evaluate the sustainability of immune-response of IN002.5.1 as a booster vaccine in healthy subjects >= 18 years of age by assessing humoral response, using blood sample.
Timepoint [1] 414899 0
Humoral response at 3 months and 6 months after administration.
Secondary outcome [2] 415553 0
