Dose Sparing Intradermal S-OIV H1N1 Influenza Vaccination Device

December 13, 2013 updated by: Dr Ivan FN Hung, The University of Hong Kong

Safety and Efficacy of Dose Sparing Intradermal S-OIV H1N1 Influenza Vaccination With the Novel Microneedle Delivery Device

Primary objective: To evaluate the safety and immunogenicity of low-dose ID S-OIV H1N1 vaccines delivered via a novel microneedle device (MicronJet600) and compare this to the full-dose standard IM injection.

Hypothesis: Low dose (20%) intradermal (ID) S-OIV H1N1 vaccine delivered via a novel microneedle device (MicronJet600) is equally effective as full-dose standard intramuscular (IM) vaccine.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective randomised, single-blinded trial in Queen Mary Hospital. We aim to recruit 200 subjects [with a minimum of 80 subjects per age group (21-65 with chronic diseases and age 65+)] who would be qualified for the Hospital Authority (HA)/ Centre for Health Protection (CHP) Mass Vaccination Program for S-OIV H1N1. These patients include all elderly at the age of 65 or above and all adult patients at the age of 21 or above with chronic illness. Subjects will be randomly assigned to receive either the full-dose (1 dose) standard Panenza vaccine at day 0 (15ug non-adjuvanted monovalent influenza A(H1N1) 2009 vaccine) delivered intramuscularly using a conventional needle (IM group) or a low-dose (1 dose) intradermal injection of Panenza vaccine at day 0 (3ug non-adjuvanted monovalent influenza A(H1N1) 2009 vaccine) delivered with the MicronJet600 (ID group).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

17 years and older (Adult, Older Adult)

What is the study measuring?
