Seasonal Flu Vaccine in Adult Transplant Recipients (Fluad Tx)

April 13, 2012 updated by: HepNet Study House, German Liverfoundation

A Phase II Study to Evaluate the Immunogenicity, Safety and Tolerability of a Seasonal Influenza Vaccine Including H1N1 in Immunocompromised Adults Who Have Undergone Solid Organ Transplantation or Bone Marrow Transplantation and in Age-Matched Healthy Volunteers

The trial investigates the efficacy of adjuvanted seasonal influenza including H1N1 Fluad (R) in immunocompromised adults who have undergone solid organ or bone marrow transplantation. It is expected that when administered once the vaccine fulfills all serological efficacy criteria required for the elderly population age 60 years and older.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Seroconversion and Seroprotection after 21 days
Time Frame: 21 days
The observed percentage of seroconversion and seroprotection, as well as the observed GMR (measured by HI) in transplanted patients at day 21 will be compared with the thresholds from the guideline for adults aged over 60 (as outlined above). This study is successful, if all three point estimates pass the corresponding efficacy criteria at day 21. For descriptive purpose two-sided 95%-confidence intervals for the rates and the GMR at day 21 will be presented.
21 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
comparison of vaccine efficacy in transplanted versus healthy subjects
Time Frame: 21 and 42 days
1. The immune response of the H1N1 vaccine is at least as effective in transplanted patients as in the healthy volunteers after one administration. For orientation in the assessment a non-inferiority-margin of 0.45 for the ratio of the geometric mean titers (GMTs) of transplanted patients and age-matched healthy volunteers at day 21 will be used and reflects what can be demonstrated with given sample size.
21 and 42 days
assessment of primary and secondary outcomes with the two other strains
Time Frame: 21 and 42 days
The primary and the first main secondary objective will also be evaluated for the other two virus strains (H3N2 and type B) of the trivalent vaccination.
21 and 42 days
safety issues as number of participants with adverse events
Time Frame: 21 and 42 days and 9 months
The safety of the study vaccine will be analyzed based on number of subjects exposed to the vaccine with respect to (1) solicited events within 7 days after injection; and (2) non-solicited adverse events at least 21 days after injection. Unsolicited events will include SAEs, AEIs (e.g. neuritis, convulsions, severe allergic reactions, angioedema, non-infectious encephalitis, vasculitis, Guillain-Barrè syndrome, demyelination, Bell's palsy), all other non-solicited AEs, which are routinely collected including onset of chronic diseases.
