E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Protection against Influenza A H1N1v disease |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
It is the overriding objective to study the optimal vaccination strategy in 2nd - 3rd trimester pregnant women with the objectives to:
• Assess whether the adjuvanted vaccine offers a meaningful benefit in pregnant women in terms of immune response over the non-adjuvanted vaccine, and if so, whether a low dose adjuvanted vaccine is sufficient.
• Assess the persistence of immune response over a 15 month time period after one single vaccination of the pregnant mother.
• Gain insight on safety of the Novartis egg-based MF59 adjuvanted H1N1 vaccine Focetria in pregnant women and their babies.
|
|
E.2.2 | Secondary objectives of the trial |
Assess the maternally transferred specific antibodies against H1N1v in the newborn.
Assess whether the immune response to H1N1 in pregnant women is different from that of non-pregnant women of similar age. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria
• Healthy pregnant and non-pregnant women living in Eastern Denmark
• Fluent in Danish
|
|
E.4 | Principal exclusion criteria |
• Heart disease, endocrine disease, tuberculosis and sarcoidosis.
• History of any anaphylaxis, serious vaccine reactions, or hypersensitivity to influenza viral proteins, to any excipients, and to eggs (including ovalbumin), and chicken proteins
|
|
E.5 End points |
E.5.1 | Primary end point(s) |
The immunogenicity criteria for success, as determined by HI, related to the EMEA/CPMP/VEG/4717/2003-Rev.1 (pandemic guideline) and EMEA/CHMP/VWP/263499/2006 (pre-pandemic guideline) are:
For adults subjects aged 18-60 years:
• The percentage of subjects with seroconversion or significant increase in HI antibody is > 40%
• The percentage of subjects achieving an HI titer ≥40 is > 70%
• The GMR is >2.5
The assessment of criteria is based on the corresponding proportions and geometric means ratio empirically found (i.e. on the point estimates).
