Trial summary

This is the initial Phase I, first-in-human study of EDV nanocells packaged with SArS-CoV-2 spike protein and alpha galacosylceramide adjuvant (EDV-plasmid-spike-GC) as a COVID-19 vaccine.

The study follows an open label, non-randomised dose escalation study design across three dose levels, whereby the EDV-plasmid-spike-GC is administered intramuscularly (IM) at a dosage dependent on the cohort in order to assess the safety and tolerability of the vaccine in healthy volunteers 18 years and older.

A total of 18 participants will be recruited to the study, at 6 per cohort. Each cohort follows the same timepoints of dosing on Days 1 and 21, followed by subsequent visits at 28 days, 3 months and 6 months. Adverse events and DLT evaluation will occur between Day 1 and 28 in order to assess the safety and tolerability of each dose level before continuing to the next cohort.

Key inclusion criteria

1.	Volunteers (male or female) non-COVID-19 infected.
2.	Aged greater than or equal to 18 years.
3.	No medical history of SARS-CoV-2 infection.
4.	The subject (or subject’s legally authorised representative) has provided voluntary 
        signed informed consent.
5.	Subject should be willing to comply with protocol scheduled study visits or 
        procedures, to the best of the subject and Investigator’s knowledge.
6.	Have a baseline body temperature of less than or equal to 37·5°C and have general 
        good health as established by medical history and physical examination. 
7.	Negative anti-COVID-19 serum antibodies (IgG and IgM) 
8.	Reproductive criteria as follows:
•	Female subjects who are of non-reproductive potential (i.e., post menopausal by 
        history - no menses for greater than or equal to 1 year and follicle-stimulating hormone 
        (FSH) level consistent with post-menopausal status; OR history of hysterectomy; OR 
        history of bilateral tubal 
        ligation; OR history of bilateral oophorectomy).
•	Female subjects of childbearing potential must have a negative serum pregnancy test 
        within 14 days of the first dose.
•	Female subjects must be willing to use highly effective methods of birth control during 
        the period of therapy and for 6 months following the last study drug administration. 
        Highly effective methods of birth control include sexual abstinence, hormonal birth 
        control, or intrauterine device (women), vasectomy or a condom with spermicide (men) 
        in combination with barrier methods. 
•	Male subjects must be willing to use highly effective methods of birth control during 
        the period of therapy and for 6 months following the last study drug administration.
•	All study subjects must be willing to ensure that corresponding sexual partners 
        practice these same methods of highly effective birth control for the same duration.

Key exclusion criteria

1.	History of a positive SARS-CoV-2 serology test.
2.	Prior intervention for SARS-CoV-2 prophylaxis.
3.	Prior treatment with a SARS-CoV-2 specific monoclonal antibody or convalescent 
        COVID-19 plasma.
4.	Significant pericardial effusions, pleural effusions or ascites.
5.	Subject has experienced a history of coronary artery disease, with or without angina 
        pectoris or myocardial infarction, symptomatic congestive heart failure (New York 
        Heart Association > Class II), uncontrolled hypertension (systolic > 160 mmHg or 
        diastolic > 100 mmHg), or cardiac arrhythmias requiring anti-arrhythmic therapy.
6.	History of uncontrolled arterial or venous thrombosis. Subjects with a history of arterial 
        or venous thrombosis are eligible if the subject is controlled on low dose molecular 
        weight heparins or low dose aspirin.
7.	Active or uncontrolled severe infection. 
8.	Received the following procedures within 28 days prior to receiving their first dose 
        (Day 1), (or has not recovered from the toxic effects of such therapy) including:
        •	radiotherapy 
        •	major surgery.
9.	Prior other therapies or procedures prior to receiving their first dose:
        •	Anticoagulation therapy (within 7 days of Study Day 1), except low molecular 
        weight heparins or low dose aspirin.
10.	QTc interval prolonging medicines should be reviewed and where possible their use 
        should be minimized and alternate medicines that are not QTc interval prolonging 
        considered as substitutes.
11.	Known allergy/hypersensitivity to investigational components or excipients 
        (monoclonal antibody infusions, interferon therapy or bacterial vaccines). 
12.	Any kind of disorder that, in the opinion of the Investigator, may compromise the ability 
        of the subject to give written informed consent and/or to comply with all required 
        study procedures.
13.	History or evidence of any other clinically significant disorder, condition or disease 
        (with the exception of those outlined above) that, in the opinion of the Investigator 
        would pose a risk to subject safety or interfere with the study evaluation, procedures 
        or completion.
14.	Platelet disorder or other bleeding disorder that may cause contraindication to 
15.	Prior administration of other investigational agents within 15 days prior to study Day 1.
16.	Prior administration of attenuated vaccine within the last 30 days.
17.	Prior administration of inactivated vaccine within the last 14 days.
