Safety and Immunogenicity of Glycovax-002 Vaccine in Healthy Adults

All the following criteria need to be met for inclusion:

1. Adults in good health as determined by the Principal Investigator or Sub-Investigator between 18 - 55 years old inclusively.
2. Able to provide informed consent and willing to comply with the study procedures.
3. BMI ≥ 18.0 kg/m2 and ≤ 35.0 kg/m2, with weight ≥ 45 kg for female subjects and ≥ 50 kg for male subjects.
4. Vital signs within the following limits: systolic blood pressure (BP) 90 - 140 mmHg, inclusive; diastolic BP 40 - 90 mmHg, inclusive; heart rate 40 - 100 bpm, inclusive; respiratory rate 10 - 22 bpm, inclusive; temperature 35.5 - 37.5 °C, inclusive.
5. Women of child-bearing potential should have a negative serum pregnancy test at Screening and a confirmatory negative urine pregnancy test at Baseline (Day 0, defined as enrolment), one before the second administration (Day 14) and one before the third and last dose administration (Day 28).
6. Agrees to practice acceptable contraception during the study if female of child-bearing potential or male partner of female of child-bearing potential.
7. Physical examination, clinical assessments, and laboratory values within normal limits during Screening, unless assessed as not clinically significant by Investigator or Delegate.
8. Has received a dose or multiple doses, of a registered COVID-19 vaccine, with the last dose more than two months prior to enrolment.

Exclusion criteria:

Participants will be excluded if any of the following criteria are met:

1. Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the Investigator, that could adversely affect the safety of the participant or confound the results of the study. Fully resolved childhood asthma is not exclusionary.
2. History of malignancy, except for non-melanoma skin cancer when excised more than two years ago and cervical intraepithelial neoplasia that has been successfully cured more than two years prior to Screening.

3. Any of the following specific conditions:

   1. Autoimmune conditions;
   2. Metabolic disorders;
   3. Glycosyl transferase disorders (including disorders of fucosyl transferase and fucose metabolism);
   4. Tn polyagglutination of erythrocyte syndrome, deficiency of galactosyl transferase, anemia, leukopenia, or thrombocytopenia;
   5. Known bacterial infections involving neuraminidase-expressing bacteria.
4. Use of any prescription medication that, in the Investigator's judgment, can interfere with the interpretation of the study tests or in the opinion of the Investigator may be contra-indicated for use with Glycovax-002. Medications that have been stable in the past 3 months may be allowed, for instance medications for hypertension, hypercholesterolemia, and gastroesophageal reflux disease (e.g. proton pump inhibitors).
5. Receipt of chronic systemic treatment with known immunosuppressant medications, or radiotherapy, within 60 days prior to enrolment.
6. Receipt of chronic systemic immunostimulant therapy (such as interferons or interleukins) within 60 days prior to enrolment.
7. Receipt of systemic corticosteroids (≥20 mg/day of prednisone or equivalent) for ≥14 days within 28 days prior to enrolment.
8. Receipt of blood/plasma products or immunoglobulins within 6 months prior to enrolment.
9. Receipt of any anticoagulation treatment (other than low dose aspirin).
10. History of myocarditis or pericarditis.
11. Presence of any sign or symptom that may suggest an active respiratory infection including COVID-19 at enrolment.
12. Any vaccination other than for influenza within 60 days prior to enrolment, or an influenza vaccination within 30 days prior to enrolment.
13. Planning to receive vaccination within 60 days after enrolment in the study.
14. Positive testing for COVID-19 within 3 months of enrolment or positive PCR testing for COVID-19 at enrolment.
15. Diagnosed with Influenza within 30 days prior to enrolment.
16. Positive for infection with HIV or with hepatitis B or C at Screening.
17. Receipt of an investigational drug within 30 days or 5 half-lives (whichever is longer) before study enrolment. For studies involving investigational products that fall within the categories mentioned in other Inclusion Criteria, the respective timelines should be respected.
18. History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (e.g., anaphylaxis).
19. History of hypersensitivity or allergic reaction to any of the components of GVX-002, including diphtheria toxoid, or squalene-based adjuvants, including Sepivac SWE™ and MF59.
20. History of drug or alcohol abuse, or positive detection test at Screening or prior to Study Drug administration for alcohol or any illicit drug including cannabis.
21. Current smoking (more than 10 cigarettes/week), current vaping (more than 80 puffs/week), current cannabis use, alcohol abuse (defined as regularly consuming more than 14 units of alcohol per week), or current drug abuse (as tested at Screening), to avoid possible impairment of immune function.
22. Presence of tattoos or scars on the upper arms that would preclude visualising any injection site reactions.
23. Any other reason (e.g., poor venous access) at the Investigator's discretion.
