PHASE1
Brief Summary
This first-in-human clinical trial is designed to evaluate the safety and immunogenicity of one administration of OVX033 coronavirus vaccine at different dose levels (100µg, 250µg and 500µg)
Detailed Description
This trial is a first-in-human phase 1, single center, randomized, double-blind, placebo-controlled study in 48 adult subjects to evaluate the safety and immunogenicity of OVX033 sarbecovirus vaccine ...

- Subjects weighing less than 50 kg.
- Subjects with abnormal safety laboratory (hematology, biochemistry, coagulation and urinalysis) parameter at screening.
- Subjects having previously received a non-licensed SARSCoV-2 vaccine or only one single dose of a licensed SARSCoV-2 vaccine.
- Subjects having presented medically significant adverse event after having received a SARS-CoV-2 licensed vaccine.
- Subjects currently treated with medications intended to prevent SARS-CoV-2 infection or disease (COVID-19) complications.
- SARS-CoV-2 infection within the past 3 months prior to enrolment, RT-PCR-confirmed SARS-CoV-2 infection at screening or ongoing symptom of COVID-19.

- Planning to receive other vaccines during the first 28 days following the study vaccine administration.
- Female subjects: pregnant, breast-feeding or of childbearing potential without appropriate contraceptive methods in place for at least 2 months before enrolment, or with positive pregnancy test at screening or on the day of vaccination. Appropriate contraceptive methods are to be maintained until the end of the trial.
- Subjects receiving treatment that can affect immune response such as systemic or high dose inhaled corticosteroids (\>800μg/day beclomethasone or equivalent; occasional inhaled corticosteroids for asthma therapy are allowed), radiation treatment, cytotoxic drugs, or current or recent (within 3 months before study entry) chronic or prolonged (\>10 days) use of systemic non-steroidal anti-inflammatory drugs, interferon, immunomodulators, allergy shots, as judged by the Investigator.
- Any known or suspected immunodeficient conditions.
- Past or current history of significant autoimmune diseases, as judged by the Investigator.
- Known or suspected infection with human immunodeficiency virus (HIV), hepatitis C virus (HCV), or hepatitis B virus (HBV) at screening.
- Current history of medical illness such as diabetes, hypertension, heart, renal or hepatic diseases, as judged by the Investigator.
- Hereditary or acquired hemorrhagic tendency or coagulation dysfunction (e.g., cytokine defects, coagulation disorders or platelet disorder), or history of serious bleeding, or history of massive bleeding after intramuscular injection, intravenous puncture or ecchymosis.
- History of receiving blood, blood components or immunoglobulins within 3 months prior to the day of vaccination, or planned to receive such product during the whole study period.
- Presence of an acute febrile illness on the day of planned vaccination or within 72 hours prior of it (oral temperature\>38.0°C; temporary exclusion criterion).
- Past or current history of any progressive or severe neurological disorder, seizure disorder or Guillain-Barré syndrome.
- Behavioral or cognitive impairment, or psychiatric disease that, in the opinion of the Investigator, may interfere with the subject's ability to participate in the study.
- Past (stopped less than 6 months before enrolment) or current smoking habit above 10 cigarettes per day.
- Past (stopped less than 6 months before enrolment) or current history of alcohol consumption (more than 2 glasses per day, more than 10 glasses per week, or absence of any days within a week without consumption. A standard glass contains 10 g of alcohol corresponding to 10 cl of wine, 25 cl of beer at 5% or 3 cl of alcohol at 40% \[Société Française d'Alcoologie, 2023\]).
- Past (stopped less than 6 months before enrolment) or current history of use of recreational drugs.
- Prophylactic or therapeutic use of any anti(retro)virals by systemic route during the study. Topical application is allowed.
- History of severe allergic reactions and/or anaphylaxis, or serious adverse reactions to vaccines or allergy to kanamycin.
