Brief Summary:
To evaluate the safety of 2 dose vaccination schedule of orally administered CoV2-OGEN1 In healthy subjects

Condition or disease Intervention/treatment Phase
SARS-CoV-2 (COVID-19) Drug: Orally Suspension of CoV2-OGEN1 Phase 1

Detailed Description:

The study will be conducted at 1 site in NZ. Patients who sign an Informed Consent and meet all eligibility criteria will be administered oral doses of 50mcg, 100mcg and 200mcg CoV2-OGEN1 on Day 1 and Day 15 during Cohort 1-3 respectively . Follow up visit in all the 3 cohorts will be performed at 1 week, 2 weeks, 3 weeks, 4 weeks, 6 weeks, 3 months, 6 months, and 12 months. One sentinel subject will be dosed at the start of each cohort and will be monitored for 24 hours post administration before the remainder of the cohort can be recruited. Each cohort will include one sentinel subject.

Dose escalation will be done after assessing all adverse events and their relatedness in atleast 9 participants out of 15 receiving Cov2-OGEN1 who have completed their week 6 FU visit.

In case three (3) or more participants receiving CoV2-OGEN1 withdraw before Visit 6 (Week 4) follow up visit, the dose escalation safety assessment will be made by assessing all Adverse Events and their relatedness status in all participants receiving CoV2-OGEN1 of the current Cohort.

    In serum IgG titer

  3. To evaluate geometric mean fold rise (GMFR) [ Time Frame: From baseline on day 43 ]
