NCT ID: NCT03849560 Completed - Influenza Clinical Trials

Safety, Reactogenicity, Immunogenicity, and Efficacy of Quadrivalent Inactivated Subunit Influenza Vaccine Grippol® Quadri and Trivalent Inactivated Polymer-Subunit Vaccine Grippol® Plus in Volunteers

Start date: November 2016
Phase: Phase 2/Phase 3
Study type: Interventional

The first Russian quadrivalent influenza vaccine was developed to improve the effectiveness of vaccination and the cost-effectiveness of preventive immunization.Current study was conducted to assess the safety, reactogenicity, immunogenicity, and efficacy of quadrivalent inactivated subunit influenza vaccine Grippol® Quadri (NPO Petrovax Pharm, LLC, Russia) versus trivalent inactivated polymer-subunit vaccine Grippol® Plus (NPO Petrovax Pharm, LLC, Russia) in subjects from 18 to 60 years old.

NCT ID: NCT03845231 Completed - Influenza Clinical Trials

Mucosal and Systemic Immunity After Viral Challenge of Healthy Volunteers Vaccinated With Inactivated Influenza Vaccine Via the Intranasal Versus Intramuscular Route

Start date: April 29, 2019
Phase: Phase 2
Study type: Interventional

Background: Influenza (flu) is a contagious respiratory virus that makes humans sick. Usually its symptoms are mild, but they can be dangerous. Researchers want to see if one way of giving the flu vaccine is more effective than another. Objective: To compare the body s ability to fight infection when a flu vaccine is given in the nose versus the arm. Eligibility: Healthy, nonsmoking adults ages 18 55. They must be willing to stay in isolation for at least 9 days. They must not have had the flu vaccine since September 1, 2018. Design: Participants must be willing to use birth control or abstinence from visit 1 until 8 weeks after getting the flu virus. Participants will have at least 3 clinic visits over about a month. Visits may include: Medical history Physical exam Blood and urine tests Nasal samples collected Heart and lung function tests At the first visit, participants will get either: Flu vaccine as injection in an arm muscle plus salt water sprays in the nose OR flu vaccine as sprays in the nose plus salt water injection in an arm Within the next few months, participants will stay in an isolation room for at least 9 days. They will be with up to 20 participants. Those who test positive for recreational drugs will leave the study. Participants will: Repeat study tests Answer questions about flu symptoms Have the flu virus sprayed into their nose once Be monitored by a medical team Participants will have at least 2 follow-up visits and repeat study tests.

NCT ID: NCT03830905 Completed - Influenza Clinical Trials

NCT ID: NCT03816878 Completed - Influenza Clinical Trials

Immunogenicity and Safety Study of Inactivated Subunit H5N1 Influenza Vaccine in Prior Recipients of Live Attenuated H2N2, H6N1 and H9N2 Influenza Vaccines and in H5N1 and Live Attenuated Vaccine Naïve Individuals

Start date: January 8, 2019
Phase: Phase 1
Study type: Interventional

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.

NCT ID: NCT03787459 Recruiting - Influenza Clinical Trials

Severe Influenza Trial of ARbidol

STAR
Start date: January 18, 2019
Phase: Phase 3
Study type: Interventional

This is a multicenter, randomised, double-blind, controlled study to assess the efficacy and safety of arbidol plus oseltamivir, compared with oseltamivir alone in approximately 200 hospitalized adults and adolescent patients with confirmed severe influenza. Patients should be randomised as soon as possible after screening (no later than 12 hours), providing they are within 7 days of symptom onset. Patients will be assigned in a 1:1 ratio to receive an arbidol plus oseltamivir, or oseltamivir plus placebo. Rescreening of patients who fail to meet the inclusion and exclusion criteria will be permitted only once, providing the time from symptom onset to randomization is still within 7 days. Arbidol/placebo will be administrated as 200mg TID from Days 1-7. Oseltamivir will be administered as 75mg twice daily from Days 1-7 (dose to be adjusted for renal impairment). Oseltamivir could be continued till influenza PCR negative. Both drugs, along with the corresponding placebo for arbidol, will be started at the time of randomization.
