The Objectives of This Study Are Study the Immunogenicity and Safety of the Flu-M [Inactivated Split Influenza Vaccine], vs. the Ultrix® Inactivated Split Influenza Vaccine, in Volunteers Who Are Over 60 Years Old
Prospective, Multicenter, Double-blind, Randomized, Comparative Immunogenicity and Safety Trial of Flu-M [Inactivated Split Influenza Vaccine], Solution for Intramuscular Injection, 0.5 ml (FSUE SPbSRIVS FMBA), vs. Ultrix®, Solution for Intramuscular Injection, 0.5 ml (FORT LLC) in Volunteers Aged Over 60 Years
調査の概要
詳細な説明
The volunteers will include in the trial will divide into two groups:
Group 1: volunteers who will receive one dose of Flu-M, solution for intramuscular injection, 0.5 mL, intramuscularly.
Group 2: volunteers who will receive one dose of Ultrix®, solution for intramuscular administration, 0.5 mL, intramuscularly.
The trial include the following periods and visits:
Screening period (up to 7 days):
• Visit 0 (day -7...-1).
Vaccination period (up to 1 day):
• Visit 1 (day 1, randomization, blood collection for serological examination, vaccination).
Follow-up period (up to 28(+2) days):
- Visit 2 (day 3, organization of trials to assess safety);
- Visit 3 (day 7(+1), organization of trials to assess safety);
- Visit 4 (day 21(+2), organization of trials to assess safety, blood collection for serological study);
- Visit 5 (day 28(+2), organization of trials to assess safety, trial completion);

説明
Inclusion Criteria:
- Presence of signed informed consent to participate in the trial.
- Volunteers (both male and female) over the age of 60 who could meet the Protocol requirements.
- Negative pregnancy test obtained from female volunteers with preserved childbearing potential.
- Consent to use adequate contraception methods (contraception methods with degree of reliability of more than 90%: a nonhormonal intrauterine device; a spermicide condom; a spermicide cervical cap; spermicide diaphragms) or total sexual abstinence during the clinical trial (until Visit 5 (day 28(+2)).
Exclusion Criteria:
- Allergic reactions to chicken protein or any previous influenza vaccination.
- Anamnestic data on the episodes of severe allergic reactions and/or diseases (anaphylaxis, Quincke's edema, polymorphic exudative erythema, serum disease etc.)
- Acute reaction (temperature above 38.5оС, edema and hyperemia over 5 cm in diameter at the injection site) or complications caused by previous administration of the drug.
- Previous vaccination 6 months before the start of the trial.
- History of leucosis, blood cancer, malignant oncological diseases.
- Guillain-Barré syndrome (acute polyneuropathy) in the medical history.
- Positive screening for HIV infection, B and C hepatitis, syphilis.
- Any confirmed or suspected immunosuppressive or immunodeficiency condition;
- Administration of immunoglobulin or blood products within the last three months before the study.
- Long-term use (more than 14 days) of immunosuppressants (including systemic corticosteroids, cytotoxic, radioactive preparations) or other immunomodulatory drugs for six months before the trial.
- Chronic diseases at the decompensation stage or in debilitating form, which can make it dangerous for the volunteer to take part in the trial.
- Progressive neurological disorders, dementia.
- Blood disorders which serve as a contradiction for intramuscular injection.
- History of alcohol or drug addiction.
- Pregnancy, breastfeeding in women with preserved reproductive performance.
- Current participation in another clinical trial or within the previous 3 months before the screening.
- Mental, physical and other problems which do not allow for appropriate assessment of own behavior and following the requirements set out in the trial protocol.
- Any other conditions which in the reasonable opinion of the clinical investigator complicate the participation of the volunteer in the trial
