Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The present study is a first-in-man clinical trial evaluating OVX836, a recombinant broad spectrum vaccine for Influenza.

This clinical trial will evaluate the safety and the immune response of increasing doses of OVX836 after intramuscular or intranasal administrations in healthy volunteers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a single center, randomized, sequential dose escalation, placebo-controlled, observer-blind study conducted in healthy subjects aged 18-49 years.

The OVX836 recombinant vaccine is based on the well conserved nucleoprotein of the Influenza virus.

Three different dose levels of OVX836 (30µg, 90µg, 180µg) will be assessed sequentially and administered either by the intramuscular route (Study Part A) or by the intranasal route (Study Part B).

There will be 6 cohorts in total with one cohort testing one dose level and one route of administration. Each study cohort will be composed of 12 subjects, with 9 subjects receiving the OVX836 vaccine and 3 subjects receiving the placebo. Each subject will receive one administration of OVX836 or placebo on Day 1 and one administration on Day 29.

The study duration for each subject is approximately 5 months.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

OVX836 (Intramuscular)

OVX836 is a recombinant Influenza vaccine based on the NP of the Influenza virus. OVX836 vaccine is a ready to use sterile liquid clear and colourless solution, presented in 2 mL glass vials filled with 1.2 mL solution. It contains 300 µg/mL of OVX836 vaccine and is formulated without adjuvant.

3 Dose levels tested: 30µg, 90 µg and 180 µg.

Group Type EXPERIMENTAL

OVX836 (Intramuscular)

Intervention Type BIOLOGICAL

2 consecutive administrations of OVX836 vaccine at Day 1 and Day 29.

Placebo (Intramuscular)

The Placebo, is Sodium Chloride 0.9 % ready to use sterile solution. The volume of placebo to be administered will be similar to the one of the experimental vaccine.

Group Type PLACEBO_COMPARATOR

Placebo (Intramuscular)

Intervention Type BIOLOGICAL

5. Clinical laboratory test results within normal reference range, or results with acceptable deviations that are judged to be Non Clinically Significant by the Investigator.
6. Blood Pressure and Heart Rate within normal reference range, or results with acceptable deviations that are judged to be Non Clinically Significant by the Investigator.
7. Are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedures.

Exclusion Criteria

1. Previous Influenza vaccination within the 6 months before screening.
2. History of significant medical illness such as auto immune diseases, immune deficiency, uncontrolled diabetes or hypertension, heart or renal or hepatic diseases, as judged by the investigator.
3. For female subjects: pregnant or breast-feeding or of childbearing potential without appropriate contraceptive methods or with positive pregnancy test at screening.
4. Having received another vaccination within 3 months prior to screening.
5. Plan to receive other vaccine during the study period.
6. Administration of any investigational or non-registered drug or vaccine within 3 months prior to the first administration of study vaccine.
7. History of receiving blood or blood component or IgG within 3 months prior to screening.
10. Individuals with any progressive or severe neurological disorder, seizure disorder or Guillain-Barré syndrome.
11. Individuals with 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.
12. History of alcoholism and/or drug abuse or tabagism (above 10 cigarettes a day).
13. Treatment that can affect immune response such as systemic or high dose inhaled corticosteroids (\>800µg/day beclometasone or equivalent), radiation treatment, cytotoxic drugs or chronic non-steroidal anti-inflammatory drugs (more than 4 weeks), interferon, immunomodulators, allergy shots, as judged by the Investigator.
