NCT ID: NCT03321968 Completed - Influenza Clinical Trials

Lot-to-lot Consistency of a Plant-Derived Quadrivalent Virus-Like Particles Influenza Vaccine in Healthy Adults

Start date: September 29, 2017
Phase: Phase 3
Study type: Interventional

This Phase 3 study is intended to assess the clinical lot-to-lot consistency in manufacturing by evaluating and comparing the immunogenicity of three consecutively manufactured lots of the Quadrivalent Virus-Like Particles (VLP) Influenza Vaccine, during the 2016-2017 influenza season, in healthy adults 18-49 years of age. A single dose of one of three consecutive lots of Quadrivalent VLP Influenza Vaccine (30 µg/strain) will be administered to 1,200 participants.

NCT ID: NCT03318315 Completed - Influenza Clinical Trials

Co-Administration of AS03 Adjuvanted A/H7N9 IIV With IIV4

Start date: February 20, 2018
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT03312699 Completed - Influenza Clinical Trials

Effects of Aging on Primary and Secondary Vaccine Responses in a 15-Year Longitudinal Cohort

SLVP033
Start date: September 19, 2017
Phase: Phase 1
Study type: Interventional

The purpose of this study is to use an existing, unique clinical cohort: the longitudinal cohort of younger (21-40 years) and elderly (>65 years) subjects whose yearly influenza vaccine responses have been studied extensively since 2007, to gain molecular and cellular mechanistic insights into the impaired vaccine responses in the elderly.

NCT ID: NCT03308825 Completed - Influenza Clinical Trials

Safety and Immunogenicity of Fluzone® Quadrivalent and Fluzone® High-Dose, Influenza Vaccines

Start date: September 11, 2017
Phase: Phase 4
Study type: Interventional

The aim of the study was to describe the safety and immunogenicity of the 2017-2018 formulation of Fluzone Quadrivalent vaccine in children 6 months to < 9 years of age, and in adults 18 to < 65 years of age, and to describe the safety and immunogenicity of the 2017-2018 formulation of Fluzone High-Dose vaccine in adults ≥ 65 years of age.

NCT ID: NCT03301051 Completed - Influenza Clinical Trials

Efficacy, Safety, and Immunogenicity of a Plant-Derived Quadrivalent Virus-Like Particles (VLPs) Influenza Vaccine in Adults

Start date: August 31, 2017
Phase: Phase 3
Study type: Interventional

This Phase 3 study is intended to assess the efficacy of the Quadrivalent VLP Influenza Vaccine during the 2017-2018 influenza season in healthy adults 18 to 64 years of age. One dose of Quadrivalent VLP Influenza Vaccine (30 μg/strain) or of placebo will be administered to approximately 10,000 participants

NCT ID: NCT03300362 Terminated - Influenza Clinical Trials

Improved Novel VaccIne CombinaTion InflUenza Study

INVICTUS
Start date: October 13, 2017
Phase: Phase 2
Study type: Interventional

A Phase IIb randomised, participant-blinded, placebo-controlled, multi-centre phase IIb efficacy study in 2030 volunteers aged 65 and over. The study will assess the safety and efficacy of the co-administration of a viral vectored vaccine, MVA- NP+M1, and the annual recommended licensed inactivated influenza vaccine (IIV). Within the main cohort 100 participants will be recruited to an immunology sub-cohort.

NCT ID: NCT03300050 Completed - Influenza Clinical Trials

Safety and Immunogenicity of a Live-attenuated Universal Flu Vaccine Followed by an Inactivated Universal Flu Vaccine

Start date: October 10, 2017
Phase: Phase 1
Study type: Interventional

The clinical study will evaluate safety and the immune response of a prime- boost regimen with a live attenuated influenza vaccine (LAIV) prime and an inactivated split influenza vaccine (IIV) boost with or without adjuvant.

NCT ID: NCT03293498 Completed - Influenza Clinical Trials

Evaluation of the Safety and Immunogenicity of a Recombinant Trivalent Nanoparticle Influenza Vaccine With Matrix M-1 Adjuvant (NanoFlu)

Start date: September 18, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

This was a Phase 1/2, randomized, observer-blinded, active-controlled trial to assess the Safety and Tolerability of a Recombinant Trivalent Nanoparticle Influenza Vaccine (Tri-NIV) with Matrix M1™ Adjuvant in Healthy Older Adults ≥ 60 Years of Age

NCT ID: NCT03287830 Completed - Influenza Clinical Trials

Flu2Text: Text Message Reminders for 2nd Dose of Influenza Vaccine
