The Effect and Safety of the Seasonal Trivalent Influenza Vaccine in Chronic Kidney Disease Patients Not on Dialysis

Phase 4

• Conditions: Chronic Kidney Disease; Immunogenicity and Adverse Drug Effect of Vaccines Influenza
• Interventions: Biological: Seasonal influenza vaccine (AdimFlu-S)

• Registration Number: NCT02105519
• Lead Sponsor: National Cheng-Kung University Hospital

Brief Summary

In recent years, several studies revealed that the current influenza vaccine strategy might be of minimal vaccine effectiveness and had a smaller effect on reducing morbidity and mortality in the end-stage renal disease population than previously thought. Thus, this also raised the question about the effectiveness of administration of influenza vaccination in chronic kidney disease patients not on dialysis. In this study, the investigators aim to evaluate the effectiveness of seasonal trivalent influenza vaccine, formulation 2013-2014, in patients with different stage of chronic kidney disease (CKD) not on dialysis.

Detailed Description

The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the licensed seasonal flu vaccine, as measured by the method of hemagglutination inhibition (HI) and ELISA-based microneutralization (microNT-ELISA) assays. All participants will be divided into 3 groups: participants refused to receive vaccination, those receive either one (week 0) or one more booster vaccination (week 0 and week 4). The investigators will collect serum of participants at the 5th weeks, 9th weeks, and 21th week post vaccination and evaluate the difference of immune response in these 3 groups.

Arm && Interventions

Group	Intervention	Description
One dose of AdimFlu-S group	Seasonal influenza vaccine (AdimFlu-S)	Participants in this group will receive one dose of the seasonal trivalent influenza vaccine (one dose of AdimFlu-S group), formulation 2013-2014, at the initiation of the study. Each administered dose contain 15 ug virus antigen for each virus strain.
Two dose of AdimFlu-S group	Seasonal influenza vaccine (AdimFlu-S)	Participants in this group (Two dose of AdimFlu-S group)will receive the seasonal trivalent influenza vaccine, formulation 2013-2014, at the week 0 and 4 weeks after the initiation of the study. Each administered dose contain 15 ug virus antigen for each virus strain.

Primary Outcome Measures

Name	Time	Method
The dynamic change of seroprotection rate related to administration of influenza virus vaccine strains (2013-2014 season) of the AdimFlu-S manufactured by Adimmune Corporation.	The seroprotection rate will be assessed at 4, 8, 20 weeks after the initiation of the study.	The primary endpoint will be the seroprotection rate which is defined as the proportion of subjects with HI titer ≥ 1:40. MicroNT-ELISA assay might also be used to evaluate the seroprotection post vaccination, which will be defined as micro-NT titer ≥1: 40 or ≥ 1:160 .

Secondary Outcome Measures

Name	Time	Method
The safety of the influenza vaccination in patients with chronic kidney disease.	the safety issue related to the vaccination will be assessed in each visit during the whole study period (20 weeks).	Patients who received influenza vaccination would be asked to record any local or systemic side effect during the first week after vaccination. Besides, the investigators would also monitor any possible adverse effect during the whole study period.
The dynamic change of seroconversion rate related to administration of influenza virus vaccine strains (2013-2014 season) of the AdimFlu-S manufactured by Adimmune Corporation.	The seroconversion rate will be assessed at 4, 8, 20 weeks after the initiation of the study.	The seroconversion is defined as the HI titer of the post-vaccination serum is at least 1:40 for those who had a negative pre-vaccination HI serum titer or a four-fold or greater increase in HI titers in subjects who had a positive pre-vaccination HAI serum titer. The seropositive is defined as the HI titer ≥ 1:10, and the seronegative is defined as HI titer \< 1:10.
The dynamic change of seroresponse rate related to administration of influenza virus vaccine strains (2013-2014 season) of the AdimFlu-S manufactured by Adimmune Corporation.	The seroresponse rate will be assessed at 4, 8, 20 weeks after the initiation of the study.	The seroresponse is defined as HI or micro-NT titer of the post-vaccination serum is at least 4-fold increase of the HI or micro-NT titer after vaccination.
