Description of intervention(s) / exposure
This is a Phase I, open label, dose-escalation study of three dose levels of the SARS-CoV-2 spike antigen administered intramuscularly (IM) in combination with a fixed dosage of PIKA adjuvant vaccine to evaluate the safety, tolerability, and immunogenicity of PIKA COVID-19 vaccine candidate in healthy individuals aged 18-65 years. The study will be conducted in New Zealand at the New Zealand Clinical Research site located in the city of Christchurch.
There will be 3 dose groups, 1 to 3 with escalating antigen dose with PIKA adjuvant in sequential cohorts. A total of 45 subjects will be enrolled in this study. Subjects in Group 1-3 will receive two doses of PIKA COVID-19 vaccine via IM administration on Days 1 and 8.
The medical monitor and principal investigator will review the safety experience of all subjects enrolled in Group 1 through Study Day 8.
Fifteen eligible subjects in each dose group will receive the study vaccine on Study Days 1 and 8 via intramuscular injection in alternative deltoid muscles. Subjects will be sequentially assigned to a dose group based on the timing of completion of screening. Enrollment of each dose cohort will start with 3 sentinel subjects, at least one male and one female. The remaining subjects will be enrolled at least 48 hours later after the 3 sentinel subjects complete the first dose administration with no safety concerns as assessed by the Principal Investigator. The Medical Monitor and Principal Investigator will review the safety data of all subjects enrolled in Group 1 through Study Day 8. If no pausing rules have been met, Group 2 will be enrolled following the enrollment practice in Group 1. Accordingly, Group 3 can be enrolled when no pausing rules are met after all subjects in Group 2 completed Day 8 visit, as assessed by the Principal Investigator and local Medical Monitor. The enrollment of Group 3 will also follow the same enrollment practice as Groups 1 and 2. The duration of the entire study is anticipated to be 8 months from the start of screening to last subject visit. The duration of each individual subject is approximately 7 months from the consent to last visit
Dosage Form: Liquid
Composition: vaccine will be formulated pending on the dose cohort. Each vaccine will have varying amount S protein.
• 5 ug S protein/1mg PIKA
• 10 ug S protein /1mg PIKA
• 20 ug S protein /1mg PIKA

Route: Intramuscular injection into the deltoid muscle, the first dose to right arm and second dose on left arm.

Outcomes
Primary outcome [1] 328175 0
To assess the safety and tolerability of the PIKA COVID-19 vaccine. Safety will be assessed by monitoring the solicited adverse events (AEs) for example Injection site reactions (pain, swelling, and erythema), fever, fatigue, nausea, headache and myalgia. Solicited adverse events will be recorded by diary card.
Timepoint [1] 328175 0
Solicited Adverse Events will be recorded on Day 1, Day 8, Day 15 post dose and during early termination if it is terminated before D15.
Primary outcome [2] 328176 0
Safety assessment will be done by monitoring unsolicited adverse events (AEs). Serious adverse events (SAEs), including suspected and unexpected serious reaction (SUSAR), adverse events of special interest (AESIs), and medically attended adverse events (MAAEs) will be recorded for the entire duration of the study.
Unsolicited AEs will be recorded for 7 days and 28 days, respectively, following each vaccine. These will be recorded by the participant in the participant diary and reviewed when the participant attends their visits at the site.
Timepoint [2] 328176 0

Primary outcome [3] 328177 0
Safety will be assessed via clinical laboratory tests including hematology, biochemistry, coagulation
Timepoint [3] 328177 0
Blood samples will be collected at screening visit, Day 8, Day 15 post dose and at early termination.
