A Phase IIb trial to examine the immune system response and safety of the FLU-v vaccine administered to healthy adults

A randomised, double-blind, placebo-controlled, single-centre phase IIb trial as part of the EU-funded UNISEC project to assess the immunogenicity and safety of different formulations and dosing regimens of FLU-v vaccine administered subcutaneously in healthy adults aged 18-60 years.

Exclusion criteria

Exclusion criteria: - Has a known allergy to any of the components of the vaccine. - Has a history of severe reaction following immunization. - Persons with immune deficiency/disorder, whether due to genetic defect, immunodeficiency disease, or immunosuppressive therapy. - Women who have a positive pregnancy test during the screening visit or who are breastfeeding. - Has a history of any of the following (reported by subjects): o Acute disseminated encephalomyelitis (ADEM); o Neoplastic disease – current or previous; o Asthma or severe allergic disease; o Bleeding disorders o Chronic Hepatitis B and/or C infection; o Chronic liver disease; o Diabetes mellitus; o Guillain-Barré syndrome; o HIV; o Rheumatoid arthritis or other autoimmune diseases; o Severe renal disease; o Transplant recipients; o Unstable or progressive neurological disorders. - Receipt of medicines/treatments that may affect evaluation of immunogenicity such as: o Oral or parenteral steroids, high-dose inhaled steroids (greater than 800 micrograms/day of beclomethasone dipropionate or equivalent) or other immunosuppressive or cytotoxic drugs (azathioprine (Imuran), cyclosporine (Neoral, Sandimmune, SangCya); monoclonal antibodies such as basiliximab (Simulect), daclizumab (Zinbryta), infliximab (Remicade), rituximab (MabThera), alemtuzumab (Campath and Lemtrada), omalizumab (Xolair), abatacept (Orencia), adalimumab (Humira and Exemptia) and etanercept (Enbrel)basiliximab (Simulect), daclizumab (Zenapax), and muromonab (Orthoclone OKT3); corticosteroids such as prednisone (Deltasone, Orasone); tacrolimus (Prograf, Advagraf, Protopic); Glatiramer acetate (Copaxone); Mycopehnolate (Cellcept); Sirolimus (Rapamune); (within 6 months of vaccination in this study) o Immunoglobulin or other blood products (within 3 months of vaccination in this study); o An experimental agent (vaccine, drug, biologic, device, blood product, or medication) within 1 month of vaccination in this study, or expects to receive an experimental agent (during the study period). o Influenza antiviral medication (within 4 weeks of vaccination in this study). - Has received any influenza vaccine within 6 months of vaccination in this study - Has influenza-like illness (a sudden onset of symptoms and at least one of the four systemic symptoms-fever or feverishness, malaise, headache, myalgia and at least one of the three respiratory symptoms-cough, sore throat, shortness of breath) or acute respiratory infection (a sudden onset of symptoms and at least one of the four respiratory symptoms-cough, sore throat, shortness of breath, coryza (Rhinitis) and a clinician’s judgement that the illness is due to an infection) within 6 months prior to vaccination in this study. These symptoms must have stopped the subject from carrying out their normal daily activities such as attending work or school for a period of at least 3 days. - Has an acute illness, including an oral temperature greater than 38 degrees Celsius, within 1 week of vaccination. - Has a history of alcohol or drug abuse within the last 2 years deemed unsuitable for inclusion by the investigator. - Any abnormal haematology values and/or serum chemistries judged by the Investigator as clinically significant.
