Active clinical trials for "Influenza in Birds"

Evaluate Safety, Tolerability and Immune response of adjuvanted H5N1 cell culture derived influenza vaccine in children.

This is a randomized, un-blinded, Phase II study in males and non-pregnant females, who are in good health, 19 to 64 years of age. This study is designed to assess the safety, reactogenicity, and immunogenicity of a pre-pandemic AS03 (GSK) adjuvanted 2017 monovalent inactivated influenza A/H7N9 vaccine, when two doses are administered 21 days apart either sequentially or simultaneously (within 15 minutes) with licensed seasonal influenza vaccine. Subjects will be randomized into one of three treatment groups. The study will enroll approximately 150 individuals who have no history of influenza A/H7N9 infection or prior receipt of an influenza virus H7 subtype vaccine. Study duration is approximately 16 months with subject participation duration of approximately 13 months. The primary objectives of this study are: 1) to assess the safety and reactogenicity following sequential or simultaneous IM administration of 2 doses of AS03-adjuvanted 2017 H7N9 IIV and one dose of seasonal influenza vaccine (IIV4); 2) to assess the serum HAI and Neut antibody responses against A/H7N9 at approximately 21 days following receipt of two doses of AS03-adjuvanted 2017 H7N9 IIV administered IM approximately 21 days apart; 3) to assess the serum HAI and Neut antibody responses against the seasonal influenza strains at approximately 21 days following receipt of IIV4.

The overall aim of this study is to evaluate the safety, immunogenicity and dose sparing effects of H7N9 influenza antigen formulated with 2 different adjuvants .

The purpose of this study is to evaluate the safety and immunogenicity of one dose of H7N9 pandemic live attenuated influenza vaccine (H7N9 pLAIV) followed by AS03-adjuvanted H7N9 pandemic inactivated influenza vaccine (H7N9 pIIV).

The main purpose of this study is to assess the usability of long-term stored H5N1 antigen and adjuvant. The study is designed to assist in stockpile management by assessing the safety, reactogenicity, and immunogenicity long-term stored influenza A/Vietnam/H5N1 vaccine when administered with or without MF59® adjuvant.

This study will assess safety and immunogenicity of GSK Biologicals' H5N1 flu candidate vaccine GSK1557484A in children 6 months to < 18 years of age.

H5N1 is an influenza virus that has the potential to cause an influenza pandemic. This study will evaluate the safety and immune response to an H5N1 influenza vaccine in people who have previously received one of two versions of an H5N1 vaccine or have previously received an H7N3 vaccine and in people who have not previously received any live attenuated influenza vaccine (LAIV).

Valuate the immune response and reactogenicity of H5N1 vaccination in a primed population (H5N3 adjuvanted or non-adjuvanted vaccine) compared to immunologically naïve subjects

This is a randomized, double-blinded, Phase II study in healthy males and non-pregnant females, 18-64 years of age. This clinical trial is designed to assess the safety, reactogenicity, and immunogenicity of a pre-pandemic 2017 monovalent inactivated influenza A/H7N9 virus vaccine (2017 H7N9 IIV) manufactured by Seqirus Inc (Seqirus) administered at different dosages (3.75 microgram mcg, 7.5 mcg and 15 mcg of hemagglutinin (HA) per dose) given with MF59(R) adjuvant manufactured by Seqirus Inc., or without adjuvant (15 mcg of HA per dose). Phosphate buffered saline (PBS) diluent manufactured by Patheon Manufacturing Services LLC will be used to achieve certain targeted doses. Approximately 371 subjects who are in good health and meet all eligibility criteria will be randomized into one of 4 study groups. The study will be conducted at up to 7 Vaccine and Treatment Unit (VTEU) sites and will last approximately 17 months, with subject participation duration of approximately 13 months. The Primary Objectives of the study are: 1) To assess the safety and reactogenicity following receipt of two doses of 2017 H7N9 IIV administered intramuscularly (IM) at different dosages approximately 21 days apart given with or without MF59(R) adjuvant; 2) To assess the serum hemagglutinin inhibition (HAI) and neutralizing (Neut) antibody responses approximately 21 days following receipt of two doses of 2017 H7N9 IIV administered IM at different dosages approximately 21 days apart with or without MF59(R) adjuvant.

The purpose of this study is to evaluate the immunogenicity and safety of inactivated subunit H5N1 influenza vaccine in individuals who have previously received live attenuated H2N2, H6N1, or H9N2 influenza vaccine, as well as in individuals who have never previously received H5N1 or other pandemic live attenuated influenza vaccines.
