Overview
Brief Summary
The purpose of this study is to determine if the administration of a seasonal flu vaccine using a PharmaJet's needle-free injection device (STRATIS) is equivalent to needle and syringe administration, as measured by laboratory tests of immune response.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Adults aged ≥18 and ≤64 years of age at the time of enrollment
- •Willing and able to give informed consent after reading the consent form and adequate opportunity to discuss the study with the investigator or qualified designee
- •Willing and able to adhere to all protocol required study procedures and to attend scheduled visits.
- •Able to receive the TIV influenza vaccine, based on University of Colorado Health (UCH) employee health flu screening guidelines.
- •Stable health status with no exclusionary medical or neuropsychiatric conditions as determined during the screening evaluation and based on the clinical judgment of the investigator or qualified designee.
- •Access to a consistent means of telephone contact
Exclusion Criteria
- •Presence of any febrile illness (oral temperature \>38°C) on the day of immunization. Such subjects will be reevaluated for enrollment after resolution of illness.
- •Presence of significant acute or chronic uncontrolled medical or neuropsychiatric illness and /or presence of any significant condition that may prohibit inclusion as determined by the investigator or his qualified designee. Uncontrolled is defined as: requiring institution of a new treatment within 1 month prior to study enrollment or change in medication dosage in the month prior to study enrollment.
- •Any immunosuppressive condition including: history of HIV infection, cancer or cancer treatment within 3 years of study enrollment, systemic glucocorticoids (in a dose ≥10 mg prednisone daily or equivalent for more than 7 consecutive days or for 10 or more days in total) within 1 month of study enrollment, or any other cytotoxic or immunosuppressive drug within 3 months of study enrollment. Any significant disorder of coagulation that would increase the risk of intramuscular injections or treatment with Coumadin derivatives or heparin.
- •Known or suspected to be allergic to eggs, chicken protein, gentamicin or influenza vaccine.
- •History of severe or previous serious adverse reaction after an influenza vaccination.
- •Receipt of any immunoglobulin and/or blood products within 3 months of immunization or planned administration of any of these products during the study period.
- •Prior history of any demyelinating disease including Guillain-Barre syndrome.
- •Presence of an active neurological disorder.
- •History of significant alcohol or drug abuse within one year prior to study enrollment.
- •Influenza vaccination or laboratory confirmed influenza infection within the previous six months before study vaccination or planned influenza vaccination during the study period.
Outcomes
Primary Outcomes
Anti Influenza Type B Hemagglutination Inhibition (HAI) Antibody Geometric Mean Titer (GMT)
Time Frame: 28 days
The GMT criterion for non-inferiority for the upper limit of the 95% CIs of the GMT ratio(GMT with NS / GMT with PJ Stratis) for each antigen to not exceed 1.5 fold.
Anti Influenza Type A/H1N1 Seroconversion
Time Frame: 28 days
Seroconversion is defined as a 4-fold rise in HAI titer in post-immunization serum relative to pre-immunization serum, or if pre-immunization serum had an undetectable titer (\<1:10), attainment of a post-immunization titer of ≥1:40.
Anti Influenza Type A/H3N2 Seroconversion
Time Frame: 28 days
Seroconversion is defined as a 4-fold rise in HAI titer in post-immunization serum relative to pre-immunization serum, or if pre-immunization serum had an undetectable titer (\<1:10), attainment of a post-immunization titer of ≥1:40.
Anti Influenza Type A/H1N1 Hemagglutination Inhibition (HAI) Antibody Geometric Mean Titer (GMT)
Time Frame: 28 days
The GMT criterion for non-inferiority for the upper limit of the 95% CIs of the GMT ratio(GMT with NS / GMT with PJ Stratis) for A/H1N1 antigen will not exceed 1.5 fold.
Anti Influenza Type A/H2N3 Hemagglutination Inhibition (HAI) Antibody Geometric Mean Titer (GMT)
Time Frame: 28 days
The GMT criterion for non-inferiority for the upper limit of the 95% CIs of the GMT ratio(GMT with NS / GMT with PJ Stratis) for each antigen to not exceed 1.5 fold.
Anti Influenza Type B Seroconversion
Time Frame: 28 days
Seroconversion is defined as a 4-fold rise in HAI titer in post-immunization serum relative to pre-immunization serum, or if pre-immunization serum had an undetectable titer (\<1:10), attainment of a post-immunization titer of ≥1:40.
Secondary Outcomes
- Number of Subjects With Complaints Within 30 Minutes Following Vaccination(Within 30 minutes post-vaccination)
- Number of Subjects With Vaccine Reactogenicity Events(Day 0, 1, 2, 3, 4, 5, and 6)
- Number of Subjects With Spontaneously Reported Adverse Events(28 days)
- Percentage of Subjects Who Received a PJ Stratis Injection Would Choose to Receive This Type of Injection Again(28 Days)
