E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Safety: To assess M-001 Safety by solicited local and systemic reactogenicity events occurring between 0 and 7 days following receipt of each of the two doses of M-001 or placebo and to assess SAEs, Medically Attended AEs (MAAEs) and new-onset of chronic medical illnesses (NOCIs) during period from Day 0 until end of first passive surveillance period in each group.
Clinical Efficacy: To assess efficacy of M-001 in the prevention of influenza disease by comparing the occurrence of PCR and/or culture confirmed influenza in the M-001 experimental group vs. placebo caused by any influenza A or B virus in association with a protocol defined Influenza Like Illness (ILI)
|
|
E.2.2 | Secondary objectives of the trial |
Clinical efficacy
1. Compare the occurrence of qualitative PCR confirmed influenza in the M-001 experimental group vs. placebo caused by any influenza A or B virus in association with a protocol defined ILI.
2. Reduced Severity of influenza illness (“breakthrough illness”) by the time to symptom alleviation/fever resolution (“alleviation/resolution”).
3. To assess in at least a subset of samples the consistency of manufacturing between 3 batches of M-001 according to their T cell responses by IFN-g production in PBMCs.
4. To assess the durability of vaccine efficacy over a second influenza season.
5. To assess influenza strain specific vaccine efficacy. |

E.3 | Principal inclusion criteria |
Subjects eligible to participate in this study must meet all of the following inclusion criteria:
1. Male and female subjects 50 years of age (inclusive) or older, mentally competent, willing and able to give the written Informed consent form (ICF) prior to study entry
2. Able to comply with the trial procedures and be available for all study visits.
3. Medically stable. (Subjects may have underlying chronic conditions such as hypertension, diabetes, ischemic heart disease, or hypothyroidism, as long as their symptoms/signs are controlled. If they are on medication for a condition, the medication dose must have been stable for at least 3 months preceding vaccination).
4. Women of childbearing potential (not surgically sterile or postmenopausal for greater than or equal to one year) and men must agree to practice adequate contraception - barrier or hormone-based methods or intra uterine device (IUD) for women and a condom for males -whose female partner has childbearing potential - throughout the study treatment and for at least up to day 81 (for female) and day 111 (for male) of the trial (i.e. 60 (for females) and 90 (for males) days after the last dose of the IMP). In addition, women of childbearing potential must have practiced the contraception for a minimum of 30 days prior to study product exposure..
5. Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 24 hours prior to study vaccination. |

E.4 | Principal exclusion criteria |
Subjects eligible to participate in this study must not meet any of the following exclusion criteria:
1. History of neurological symptoms or signs, or anaphylactic shock following administration of any vaccine.
2. Known or suspected (or have a high risk of developing) impairment/alteration of immune function (excluding that normally associated with advanced age).
3. Receipt of: a) Current (including within 60 days or planned during the study) daily use of immunosuppressive drugs: i) systemic glucocorticoids >/= 10 mg prednisone per day ii) cytotoxic drugs b) Investigational drugs within 30 days before, or planned during, the study c) Blood products within 3 months before, or planned during, the study d) Influenza vaccine within 6 months before the study) Other vaccines within 30 days before, or planned during, the study
4. Any serious disease such as: cancer, autoimmune disease, advanced arteriosclerotic disease or complicated diabetes mellitus, chronic obstructive pulmonary disease (COPD) that requires oxygen therapy, acute or progressive hepatic disease, acute or progressive renal disease, or congestive heart failure, as judged by the PI.
5. An acute illness, including an axillary temperature greater than 38ºC, occurred within 1 week before first vaccination
6. Anatomical deficiencies which exclude possibility of taking NP swab
7. Women who are breastfeeding or planning pregnancy during the period of the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
Safety:
To assess M-001 Safety by solicited local and systemic reactogenicity events occurring between 0 and 7 days following receipt of each of the two doses of M-001 or placebo and to assess SAEs, Medically Attended AEs (MAAEs) and new-onset of chronic medical illnesses (NOCIs) during period from Day 0 until end of first passive surveillance period in each group.
Clinical Efficacy:
Compare the occurrence of culture confirmed influenza in the M-001 experimental group vs. placebo (≥ 15 days after the second vaccination until epidemiological levels of influenza are low as defined by the medical director) caused by any influenza A or B virus in association with a protocol defined Influenza Like Illness (ILI is defined as symptoms that interfere with normal daily activities and that include one of the following respiratory symptoms (sore throat, cough, sputum production, nasal discharge, wheezing or difficult breathing) and at least one additional systemic symptom [fever (oral temperature >37.2°C), headache, myalgia and/or arthralgia, chills, and fatigue (tiredness for at least 12 hours)]. NP (Nasopharyngeal) swab will be collected from participants who meet the ILI definitions for qualitative PCR analysis of influenza A and/or B virus. Influenza positive samples by PCR will be further analysed for culture confirmation. |

1. Compare the occurrence of qualitative PCR confirmed influenza in the M-001 experimental group vs. placebo (≥ 15 days after the second vaccination until epidemiological levels of influenza are low as defined by the medical director) caused by any influenza A or B virus in association with a protocol defined ILI (ILI is defined as symptoms that interfere with normal daily activities and that include one of the following respiratory symptoms (sore throat, cough, sputum production, wheezing or difficult breathing) and at least one additional systemic symptom [fever (oral temperature >37.2°C), headache, myalgia and/or arthralgia, chills, and fatigue (tiredness)]. Nasopharyngeal swab will be collected from participants who meet the ILI definitions for PCR analysis of influenza A and/or B virus.
2. Reduced Severity of influenza illness (“breakthrough illness”)
Reduction of illness severity: The time to symptom alleviation/fever resolution (“alleviation/resolution”), which can be defined as the first time point at which all of the six influenza symptoms (body aches and pains, cough, fatigue, headache, nasal congestion, and sore throat) were either absent or mild and fever had resolved, with both (resolution of all 6 symptoms and fever) maintained for at least 21.5 hours (i.e., 24 hours minus 10%, i.e., lower limit of detection of an [approximately] 1 day improvement in resolution of illness).
3. To assess in at least a subset of samples the consistency of manufacturing between 3 batches of M-001 according to their T cell responses by ICS and FACS analysis for IFN-g production in PBMCs. |
