Trial Summary

What is the purpose of this trial?

In solid organ transplant (SOT) the receipt of influenza vaccine in an influenza season is associated with decreased disease severity as demonstrated by the presence of pneumonia and ICU admissions. Different strategies have been assessed to optimize vaccine efficacy and immunogenicity of the influenza vaccine in the solid organ transplant recipient (SOTR). The primary objective of the study is to evaluate the immunogenicity of 2 doses of the high dose influenza vaccine utilizing neutralizing antibody assays. A control group receiving 1 HD influenza vaccine will be included.

Do I have to stop taking my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. However, if you have received certain medications like ATG, carfilzomib, rituximab, or basiliximab in the past 3 months, you cannot participate.

Is the high-dose flu vaccine safe for humans?

The high-dose flu vaccine, known as Fluzone High-Dose Quadrivalent, has been studied for safety in both children and adults. Most reported side effects are mild, such as injection site reactions, fever, headache, and nausea. Serious side effects are rare, and no new safety concerns have been identified in recent reviews.12345

How does the drug Fluzone High-Dose Quadrivalent differ from other treatments for solid organ transplant recipients?

Fluzone High-Dose Quadrivalent is unique because it contains a higher dose of the flu vaccine specifically designed to provide better protection for people with weakened immune systems, such as solid organ transplant recipients, compared to standard flu vaccines.678910

Safety and immunogenicity of high doses of quadrivalent influenza vaccine in children 6 months through [2021]Quadrivalent high-dose inactivated influenza vaccine (Fluzone® High-Dose Quadrivalent, IIV4-HD) was licensed in the USA in 2019 for adults ≥ 65 years of age. This Phase II study examined safety and immunogenicity of 3 dose formulations of IIV4-HD in healthy children. In a randomized, modified double-blind, active-controlled trial in the USA and Canada, 661 children aged 6 months through
Postmarketing safety surveillance of high-dose quadrivalent influenza vaccine: Reports to the Vaccine Adverse Event Reporting System. [2022]On November 4, 2019, the Food and Drug Administration approved high-dose quadrivalent influenza vaccine (Fluzone High-Dose Quadrivalent; QIV-HD) for active immunization for the prevention of influenza disease in individuals 65 years of age and older. A prelicensure randomized, active-controlled, modified double-blind trial did not reveal any major differences in adverse events following QIV-HD versus Fluzone High-Dose (trivalent). To improve our understanding of the safety profile of QIV-HD, we reviewed and summarized reports of adverse events after QIV-HD to the Vaccine Adverse Event Reporting System (VAERS). From July 30, 2020 through June 30, 2021, VAERS received 2,122 reports after QIV-HD. The vast majority (2,018; 95.1%) were non-serious and included events that had been observed in the prelicensure clinical trial, such as injection site reactions, fever, headache, and nausea. The most common serious events included Guillain-Barré syndrome, cellulitis or other local reactions, constitutional signs/symptoms (e.g., fever), and cardiovascular events. Our review did not reveal any new safety concerns. This information may enable policy makers, health officials, clinicians, and patients to make a more informed decision regarding vaccination strategies.

Does low-dose seretide reverse chronic obstructive pulmonary disease and are the benefits sustained over time? An open-label Swedish crossover cohort study between 1999 and 2005. [2017]Chronic obstructive pulmonary disease (COPD) still poses a formidable challenge to patients and clinicians alike. A fixed-dose dry powder combination inhaler, Seretide/Advair, containing salmeterol and fluticasone, is licensed in the European Community for the treatment of moderate to severe COPD in the strength of 50/500 microg twice daily (BID). Several studies have investigated the effects of this combination and show improved forced expiratory volume in 1 s (FEV(1)), quality of life, and a decrease of exacerbations. Most of the studies have run for less than 1 year. The aim of this investigator-initiated, independent study was to elucidate if the combination containing 50 microg of salmeterol and 250 microg of fluticasone BID could be shown to have the same beneficial effect as the higher dosage, and if the effect could be sustained over time.
Improved safety with equivalent asthma control in adults with chronic severe asthma on high-dose fluticasone propionate. [2019]High-dose inhaled corticosteroids (ICS) have been associated with the same side-effects as oral corticosteroids. Beclomethasone dipropionate (BDP) and budesonide (BUD) in doses greater than 2000 microg/day are used regularly in severe asthma, despite the fact that safety and efficacy data at such high doses are limited. Fluticasone propionate (FP) has been promoted as being twice as potent clinically as BDP or BUD at doses of 2000 microg/day or less with a similar safety profile. The aim of this study was to compare the efficacy and safety of FP with BDP and BUD in 133 symptomatic adult asthmatics requiring at least 1750 microg/day of BDP or BUD.

Equivalent Systemic Exposure to Fluticasone Propionate/Salmeterol Following Single Inhaled Doses from Advair Diskus and Wixela Inhub: Results of Three Pharmacokinetic Bioequivalence Studies. [2021]Background: Wixela® Inhub® was developed to deliver inhaled fluticasone propionate/salmeterol (FP/S) combination as a substitutable generic equivalent to Advair® Diskus®. These studies aimed to confirm the pharmacokinetic bioequivalence (BE) of FP/S after single doses of Wixela Inhub (test [T]) and Advair Diskus (reference [R]). Methods: Three open-label, randomized, two-way crossover, single-dose studies in healthy subjects (N = 66 each) compared the systemic exposure of FP and salmeterol after inhalation from three dose strengths of FP/S (100/50, 250/50, or 500/50 μg) delivered from T and R. Primary BE endpoints were the area under the plasma concentration-time curve from time = 0 to the last measurable concentration (AUC(0-t)) and the maximum observed plasma concentration (Cmax) for both FP and S. The BE acceptance criteria specified that the 90% confidence intervals (CIs) of the geometric mean T/R ratios for AUC(0-t) and Cmax can be contained within 0.80-1.25 for both FP and salmeterol. Results: Wixela Inhub met the acceptance criteria for BE for FP and salmeterol at each dose strength. Estimated AUC(0-t) and Cmax geometric mean ratios (T/R [90% CI]) for FP were, respectively, 1.04 (1.00-1.08) and 0.92 (0.87-0.96) for 100/50 μg FP/S, 1.07 (1.02-1.13) and 1.01 (0.95-1.07) for 250/50 μg, and 0.97 (0.92, 1.00) and 0.90 (0.86-0.93) for 500/50 μg. Estimated AUC(0-t) and Cmax ratios for salmeterol were, respectively, 1.08 (1.04-1.11) and 1.00 (0.94-1.04) for 100/50 μg FP/S, 1.03 (0.99-1.07) and 0.93 (0.87-1.00) for 250/50 μg, and 1.00 (0.96-1.04) and 0.86 (0.81-0.91) for 500/50 μg. FP/S at all doses via both T and R was comparably well tolerated. Conclusions: Wixela Inhub was bioequivalent to Advair Diskus at all three dose strengths for both FP and S, providing direct evidence of equivalent systemic safety and indirect evidence for equivalent pulmonary deposition.
