Conditions: Childhood Asthma
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 26
Healthy volunteers: no

Brief summary:
The purpose of this study is to see how two doses of Flunisolide HFA (an FDA approved inhaled medication to treat asthma) affect the small airways in children with asthma.

Detailed description:
This is a prospective, randomized, parallel, open label study. The primary aim is to compare the average change in spirometric values (Forced expiratory volume 1 (FEV1) and Forced Expiratory Flow 25-75% (FEF 25-75%) and Impulse Oscillometry System (IOS) values (Resistance at 5 Hz (R5), Resistance at 20 Hz (R20), Area of reactance (AX), Resonant frequency (Fres)) from baseline to week 6 from participants randomized flunisolide hydrofluoroalkane (HFA) 1 inhalation BID and to flunisolide HFA 2 inhalations BID. The change in scores from baseline to six week follow up will initially be compared using paired t-tests and Chi-squared tests for trend. Repeated measurements will be analyzed using generalized linear mixed-effects regression modeling (GLMM) techniques. For continuous outcomes (e.g. FEV1, FEF 25-75%, Fres, reactance at 5 Hz (X5), AX, R5-R20). The identity link function and normal distribution will be used. For count data (e.g., use of Beta-agonists, episodes of coughing, episodes of wheezing, etc.) the log link function and the Poisson distribution will be used. If we dichotomize outcomes (e.g., a Beta-agonist was used, coughing occurred, etc.) the logit link function and Bernoulli distribution will be used.

Arms:
arm 1: Patients will receive inhaled Flunisolide HFA 80 mcg twice per day for a total of 160 mcg per day over the 6 week study period arm 2: Patients will receive inhaled Flunisolide HFA 160 mcg twice per day for a total of 320 mcg per day over the 6 week study period

this research. 
Purpose
The purpose of this study is to see how Flunisolide HFA (an FDA approved inhaled medication to 
treat asthma) affects the lungs in asthma, especially the small airways deeper in the lungs as 
measured by tests that are commonly used in the day-to-day care of patients with asthma.
Procedures
To participate in this study, you must meet certain criteria that will be evaluated and determined by 
the study doctor and/or study staff.  Your medical history and current medical condition will be 
reviewed.  You will be asked for personal information, such as your date of birth and race/ethnicity. 
The study doctor in charge of this study or a member of the study doctor’s staff will discuss with you 
all requirements for participation in this study.
Your participation in this study will last for up to 14 weeks.  If you consent to participate, you will have 
the following procedures while you are in this study.

Visit 1: (1 hour)
At this visit you can expect us to do the following:

Ask you to review and sign this informed consent and HIPAA document

Obtain your past medical history and any medications you have taken in the past 4 weeks or 
are currently taking

Ask you to fill out a simple questionnaire to help show how well your asthma has been 
controlled.

Measure oxygen saturation on room air

Perform a physical exam (weight, height, blood pressure, heart rate, temperature, etc)

Collect urine to preform a pregnancy test if you are a female who could be pregnant

Require that you have the following procedures:
o
Spirometry  - a breathing test where you will be asked to take a very deep breath and 
blow out as hard and quick as you can into a mouthpiece connected to a computer
o
Impulse oscillometry - a test where you will be asked to sit up straight and breathe 
normally for about 30 seconds while you have a mouthpiece in place.  You will hear a 
quiet “ticking” sound during the procedure but it is painless and does not require 
significant effort.  
This visit will determine if you are eligible to be enrolled in the study.  If you meet the study criteria, 
we will ask you to continue in the study and schedule a second visit.
Visit 2: (1 hour; 1 to 56 days after visit 1))
At this visit you can expect us to do the following:

There may also be other procedures required as part of the study.  The risks associated with Impulse 
oscillometry and spirometry include becoming short of breath when asked to inhale and exhale 
deeply and quickly.  
In addition, you may suffer harms that we have not seen before. 
Possible Pregnancy Risks 
You should discuss pregnancy risks with your doctor before signing this consent form. Women who 
are pregnant or breast feeding may not participate in this research study.  If you are pregnant or 
become pregnant, your unborn child may suffer harms that we have not seen before. If you (or your 
partner) become pregnant while in this study, the sponsor may ask to follow the outcome of the 
pregnancy.  If you agree to allow the study doctor to follow your pregnancy, you will be asked to read 
and sign a separate consent form for permission to follow the outcome of your pregnancy.  
If you are a man taking part in the study and your partner becomes pregnant, the study doctor may 
ask you to ask your partner for permission to follow her pregnancy.  If she agrees, she will be asked 
to sign a separate consent form mentioned above.
Before starting this research study, females able to have children will have a pregnancy test.  Talk to 
your doctor about the best method of birth control to use while you are in this study.  It is important 
that you call your study doctor at 502-588-4940 right away if you become pregnant or father a child 
during the course of this study.  If you or your partner becomes pregnant, a decision may have to be 
made whether or not to end the pregnancy.  
We do not know the effects of flunisolide on an unborn baby.  There is a risk that your unborn baby 
could be harmed if you become pregnant during your participation in the study.  (If you ask, your 
study doctor will discuss the possible risks to your unborn child and your options should you become 
pregnant while in this study.)

DURATION OF 
SUBJECT 
PARTICIPATION AND 
DURATION OF STUDY 
Study visits will occur at screening, baseline, and 6 weeks (± 1 
week). Total duration of subject participation will be up to 8 weeks.  
As enrollment will occur over approximately 12 months, total 
duration of the study is expected to be up to 14 months (12 months 
enrollment plus about 2 months for the last subjects to complete 
treatment). 
Screening, enrollment, 
randomization and 
treatment 
Screening: At the Screening visit, a focused, standardized history and 
physical exam will be conducted by one of the physicians on the 
research team.  Patients will also undergo pre and post bronchodilator 
spirometry.  Spirometry values prior to the administration of 
bronchodilator will be used to assess patient’s enrollment status. 
Enrollment and Randomization: At the Baseline visit, patients will 
undergo a repeat focused, standardized history and physical exam.  
Spirometry and IOS will both be undertaken pre and post 
bronchodilator (in this order: IOS, spirometry, bronchodilator, IOS, 
spirometry). 
Treatment: Subjects will receive treatments twice per day for 6 ± 3 
days. 
CONCOMITANT 
MEDICATIONS 
Allowed: All standard therapies 
Prohibited: Other forms of ICS, LABAs  
Efficacy Evaluations 
Physiologic effects (change in lung function between baseline and end 
of treatment) and Clinical Effects (number of asthma exacerbations, 
asthma control scores) will be compared between subjects randomized

SAFETY 
EVALUATIONS 
Rates of adverse events, withdrawal, adherence to treatment, rate of 
asthma exacerbations will be monitored.  
SAFETY 
MONITORING 
As this is an FDA approved drug being used in approved populations 
at approved doses, the elements listed under “safety evaluations” as 
above will be tracked by the PIs but no formal data safety review 
board will be in place. 
STATISTICS 
Primary Analysis Plan 
The primary aim is to compare the average change in spirometric 
values (FEV1 and FEF25-75%) and IOS values (R5, R5-R20, AX, Fres) 
from baseline to Week 6 from participants randomized flunisolide 
HFA 1 inhalation BID and to flunisolide HFA 2 inhalations BID. The 
change in scores from baseline to six-week follow-up will initially be 
compared using paired t-tests and Chi-squared tests for trend. 
Repeated measurements will be analyzed using generalized linear 
mixed-effects regression modeling (GLMM) techniques. For 
continuous outcomes (e.g., FEV1, FEF 25-75%, Fres, X5, AX, R5-R20.) 
the identity link function and normal distribution will be used. For 
count data (e.g., use of Beta-agonists, episodes of coughing, episodes 
of wheezing, etc.) the log link function and the Poisson distribution 
will be used. If we dichotomize outcomes (e.g., a Beta-agonist was 
used, coughing occurred, etc.) the logit link function and Bernoulli 
distribution will be used. Statistical analyses will be performed using 
SAS® Version 9.3 (SAS Institute Inc., Cary, NC). 
Rationale for Number 
of Subjects 
Based on our preliminary studies, we anticipate that 10% of all 
potential participants will not be eligible and/or willing to participant; 
and that 10% of the eligible/willing participants will be lost to follow-
up. Therefore, we will recruit a total of n=50 individuals for the 
current study. This is a feasible sample size for the research team to 
recruit and enroll in the current study. Power calculations were based

on the anticipated total sample size (n=40) that will be available for 
complete analysis.  
 
We will develop separate mixed-effects general linear models for each 
of the continuous outcomes. From the anticipated sample size (n=40) 
the study has 86% power to detect a 10% main effect of each 
treatment for each outcome, our anticipated effect size given 
preliminary studies. When using count data the study has 94% power 
to detect a 10% decrease in the rate of outcomes (coughing, wheezing, 
etc.), our anticipated change in the rate. Using the dichotomized 
version of some outcomes, this study has 80% power to detect on 
odds ratio of 1.32 with a two sided α=0.05 (n=40). Therefore, we have 
more than sufficient numbers of participants in each comparison 
group.

BACKGROUND 
Flunisolide HFA is an inhaled corticosteroid that is a reformulated version of the older CFC preparation.  The CFC formulation was approved 
in 1981 and had been in use as an asthma controller since with good results.1  The HFA formulation, which is in solution as opposed to 
suspension, has superior lung deposition when compared to its CFC counterpart (68% versus 20%).1  Studies have demonstrated flunisolide 
HFA’s effectiveness with regards to controlling airway inflammation and improving lung function2,3 while maintaining an excellent side 
effect profile, including no measurable effect on growth over one year.4  These attributes make it ideal for use in pediatric patients in whom 
growth suppression is a common concern.  In addition, the current device used for delivery has a built-in spacer to ensure optimal lung 
deposition.   
 
It is known that flunisolide HFA is uniformly distributed throughout all airways, with deposition approaching 68% and less drug being 
deposited in the oral cavity than larger molecule inhaled corticosteroids.  Fluticasone, for example, has a larger particle size and results in 
about 20% lung deposition, mainly in the central airways. Despite this, there is little data that specifically examines the effect of flunisolide 
HFA on small airway parameters in children with asthma.  We propose a randomized parallel study between flunisolide HFA 80 mcg twice a 
day and 160 mcg twice a day to determine the effect of each dose on spirometry and impulse oscillometry (IOS) parameters.   
 
Based on the small molecule size and even lung deposition, we hypothesize that we will see a dose dependent significant improvement 
in small airway parameters (FEF 25-75%, AX, Fres, X5, R20-R5) with flunisolide.  Secondary outcome measures will include clinical 
effects such as frequency of coughing and wheezing, number of short acting beta agonists used, oral steroid doses required, emergency 
department visits, and hospitalizations.  If the results support our hypothesis this will address an important problem in the field and shift 
current clinical practice paradigms by a refinement in interventions.  It may also provide the foundation for future studies to directly compare 
flunisolide to other coarse molecules inhaled corticosteroids.  

Prevalence and Impact of Asthma 
Asthma is one of the most prevalent chronic diseases worldwide, with a substantial burden of disease in the United States.  The condition is 
characterized by extensive airway inflammation leading to variable airflow obstruction, airway hyperresponsiveness and symptoms of 
wheezing, coughing and dyspnea.  Asthma is responsible for an estimated 450,000 hospitalizations in the United States annually (nearly 
200,000 of these in children) at considerable cost.  Many efforts have been made in attempting to reduce this number.  Chronic therapies, 
consisting primarily of inhaled corticosteroids to reduce airway inflammation and beta-two agonists for acute symptoms, are well recognized 
by National Heart, Lung, and Blood Institute asthma guidelines for treatment.  Despite this, medication adherence remains a major barrier in 
care.5,6

ICS Therapy in Asthma 
As noted, chronic therapy with ICS is widely recongized as standard of care, first line therapy for patients with persistant asthma.  Compared 
with oral corticosteroids, ICS are effective, safe, and exert a local anti-inflammatory effect directly at the site of pathology.  ICS can be 
delivered by a number of mechanisms, the most common of which are pMDIs, dry powdered inhalers, and nebulizers.  Failure to correctly use 
these devices are a common cause of inadvertant non-adherance and is associated with poor asthma control.7-11  Nebulization may be an ideal 
delievery mechanism for very young or old patients, acutely ill patients, or those with neurologic or developmental impairments.12  Selection 
of ICS by a physician is an individulized process, with the focus on selecting a product with a delivery device that the patient will be able to 
use easily as well as a molocule with ideal pharmacokinetics and pharmacodyamics.  An ideal ICS would be one that has high lung 
deposition, prolonged pulmonary residency times and low systemic absoprtion (reflected by an excellent safetey profile).13  While beyond the 
scope of this discussion, comprehensive reviews comparing ICS molocules have been published and are of  great reference to the practioner.13  

CFC and HFA Flunisolide 
An excellent, comprehensive review of flunisolide was recently published by Melani.12  Flunisolide was first discovered in 1965 and 
approved for inhalation via a CFC-MDI in the United States in 1981.  Prior studies demonstrated a clinical profile similar to other CFC ICSs 
such as BDP, fluticasone and budesonide.  Lung deposition of this formulation was estimated to be 10% of the delivered dose.  Secondary to 
environmental concerns, CFC MDIs have been phased out with CFC flunisolide being removed from market in 2010.  Reformulated versions 
of these drugs have been developed with HFA MDIs.  While some versions of these reformulated drugs were created to match their previous 
CFC counterparts, others (including flunisolide) were formulated as solutions and deliver extrafine aerosols that have improved deposition 
even into the distal airways.  The mass median aerodynamic diameter of CFC funisolide was 3.8 µm while the HFA formulation has a 
MMAD of only 1.2 µm.  Studies have demonstrated that this smaller particle size results in significantly less deposition in the mouth, pharynx 
and GI tract and greater deposition in the peripheral lung with improved homogeneity of deposition throughout the respiratory tract.  This 
results in reduced local side effects such as thrush as well as less systemic bioavailability.  HFA flunisolide is FDA approved and has recently 
been marketed in the US at strength of 80 µg per dose.  The device has a 50 mL inhalation chamber attached to assist with medication 
delivery to the lungs.  The recommended starting dose in adults is 160 µg twice daily (recommended maximum dose 320 µg twice daily) and 
in children (ages 6-11) is 80 µg twice daily (recommended maximum dose 160 µg twice daily).   

Clinical Pharmacology 
This section (through 1.6) is derived from data directly from the package insert for flunisolide HFA:   
Mechanism of Action: Flunisolide has demonstrated marked anti-inflammatory activity in classical test systems. It is a corticosteroid that is 
several hundred times more potent than cortisol in animal anti-inflammatory assays, and several hundred times more potent than 
dexamethasone in anti-inflammatory effect as determined by the McKenzie skin blanching test. The clinical significance of these findings is 
unknown. The precise mechanism of corticosteroid action is unknown. Airway inflammation is an important component in the pathogenesis

of asthma. Corticosteroids have been shown to have a wide range of anti-inflammatory effects, inhibiting both inflammatory cells (e.g. mast 
cells, eosinophils, neutrophils, macrophages, and lymphocytes) and release of inflammatory mediators (e.g., histamine, eicosanoids, 
leukotrienes, and cytokines) involved in allergic and non-allergic mediated inflammation. These anti-inflammatory actions of corticosteroids 
may contribute to their efficacy in asthma. 
Pharmacokinetics: All the data described below is based on studies conducted in subjects 18 to 51 years of age.  
Absorption: Flunisolide is rapidly absorbed after oral inhalation. Mean values for the time to maximum concentration, Tmax, of flunisolide 
range from 0.09 to 0.17 hr after a single 320 mcg dose of AEROSPAN Inhalation Aerosol. The corresponding mean values for the maximum 
concentration, Cmax, of flunisolide vary from 1.9 to 3.3 ng/mL. Oral bioavailability is less than 7%. Over the dose range of 80 mcg to 320 
mcg of  
AEROSPAN Inhalation Aerosol, values for Cmax increase proportionately with dose after single as well as multiple dose administration.  
Distribution: Flunisolide is extensively distributed in the body, with mean values for apparent volume of distribution ranging from 170 to 
350 L after a single 320 mcg dose of AEROSPAN Inhalation Aerosol.  
Metabolism: Flunisolide is rapidly and extensively converted to 6ß-OH flunisolide and to water-soluble conjugates during the first pass 
through the liver. Conversion to 6ß-OH flunisolide, the only circulating metabolite detected in man, is thought to occur via the cytochrome 
P450 enzyme system, particularly the enzyme CYP3A4. 6ß-OH flunisolide has a low corticosteroid potency (ten times less potent than 
cortisol and more than 200 times less potent than flunisolide). Maximum levels of 6ß-OH flunisolide were 0.66 mcg/mL after a single 320 
mcg dose of AEROSPAN Inhalation Aerosol, and 0.71 mcg/mL after multiple doses of AEROSPAN Inhalation Aerosol.  
Excretion: Urinary excretion of flunisolide is low. Less than 1% of the administered dose of flunisolide is recovered in urine after inhalation. 
The half-life values for 6ß-OH flunisolide range from 3.1 to 5.1 hrs after administration of AEROSPAN Inhalation Aerosol in the dose range 
of 160 mcg to 320 mcg.  
Disposition and Elimination: Twice daily inhalation administration of flunisolide hemihydrate for up to 14 days did not result in appreciable 
accumulation of flunisolide. Upon multiple dosing with 160 mcg and 320 mcg, the Cmax values were 1.0 ng/mL and 2.1 ng/mL, respectively. 
The corresponding AUC0-12hr values were 1.2 ng.hr/mL and 2.5 ng.hr/mL.  
Flunisolide is rapidly cleared from the body, independent of route of administration or dose administered. Flunisolide is not detectable in 
plasma twelve hours post-dose. After administration of 320 mcg of AEROSPAN Inhalation Aerosol the elimination half-life ranges from 1.3 
to 1.7 hours. After a single 320 mcg dose, mean oral clearance values, not adjusted for bioavailability, range from 83 to 167 L/hr.  
Special Populations: There were no gender differences for flunisolide after single and multiple dose administration of the AEROSPAN 
Inhalation Aerosol. Formal pharmacokinetic studies using flunisolide were not carried out in any other special populations.

Pharmacodynamics: Dose finding for AEROSPAN Inhalation Aerosol was based on comparability of systemic exposure to flunisolide CFC 
inhalation aerosol. The effect of flunisolide CFC inhalation aerosol and AEROSPAN Inhalation Aerosol on pharmacokinetics and 12-hour 
plasma cortisol levels was investigated in two studies. In both studies, the Cmax and AUC of flunisolide, 6β-OH flunisolide, and 12-hour 
plasma cortisol measurements were comparable for 1000 mcg of flunisolide CFC inhalation aerosol and 320 mcg of AEROSPAN Inhalation 
Aerosol. The first was a parallel arm study in 31 subjects. Pharmacokinetics and plasma cortisol levels were determined after single and 
multiple doses of flunisolide CFC inhalation aerosol 1000 µg and AEROSPAN Inhalation Aerosol 160 µg or 320 µg administered twice daily 
for 13.5 days. At steady state, flunisolide mean peak plasma concentrations from flunisolide CFC inhalation aerosol 1000 mcg and 
AEROSPAN Inhalation Aerosol 320 mcg were found to be 2.6 ng/mL and 3.4 ng/mL, respectively. The corresponding mean AUC values for 
the 12-hr dosing interval were 5.7 ng.hr/mL and 4.7 ng.hr/mL, respectively. At steady state, the mean peak plasma concentrations of 6β-OH 
flunisolide from flunisolide CFC inhalation aerosol 1000 mcg and AEROSPAN Inhalation Aerosol 320 mcg were found to be 0.9 ng/mL and 
0.3 ng/mL, respectively. The corresponding mean AUC values for the 12-hr dosing interval were 3.8 ng.hr/mL and 1.1 ng.hr/mL, 
respectively. The second was a crossover study in 11 subjects after single doses of flunisolide CFC inhalation aerosol  
1000 mcg or AEROSPAN Inhalation Aerosol 320 mcg. The mean peak plasma concentrations of flunisolide from the flunisolide CFC 
inhalation aerosol 1000 mcg and AEROSPAN Inhalation Aerosol 320 mcg were found to be 2.5 ng/mL and 3.3 ng/mL, respectively. The 
corresponding mean AUC values were 5.1 ng.hr/mL and 5.8 ng.hr/mL, respectively. The mean peak plasma concentrations of 6β-OH 
flunisolide from flunisolide CFC inhalation aerosol 1000 mcg and AEROSPAN Inhalation Aerosol 320 μg were found to be 0.8 ng/mL and 
0.3 ng/mL, respectively. The corresponding mean AUC values were 3.8 ng.hr/mL and 2.3 ng.hr/mL, respectively. 

Pediatric Use of Flunisolide:  
The safety and effectiveness of AEROSPAN Inhalation Aerosol has been studied in children 4- 17 years of age. In clinical studies, the 
efficacy of AEROSPAN Inhalation Aerosol was not established in children 4-5 years of age, although the adverse reaction profile observed in 
patients exposed to AEROSPAN Inhalation Aerosol was similar between the 4-5 year age group (n=21), the 6-11 year age group (n=210), the 
12-17 year age group (n=30), and those patients 18 years of age and older (n=258). The safety and effectiveness of AEROSPAN Inhalation 
Aerosol has not been studied in patients less than 4 years of age.  
Effects on Growth: Controlled clinical studies have shown that orally inhaled corticosteroids may cause a reduction in growth velocity in 
pediatric patients. In these studies, the mean reduction in growth velocity was approximately one cm per year (range 0.3 to 1.8 cm per year) 
and appears to depend upon the dose and duration of exposure. This effect was observed in the absence of laboratory evidence of 
hypothalamic-pituitary-adrenal (HPA) axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic 
corticosteroid exposure in pediatric patients than some commonly used tests of HPA axis function. The long-term effects of this reduction in 
growth velocity associated with orally inhaled corticosteroids, including the impact on final adult height, are unknown. The potential for 
“catch up” growth following discontinuation of treatment with orally inhaled corticosteroids has not been adequately studied. The growth of 
pediatric patients receiving orally inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, should be monitored routinely (e.g., via

stadiometry). The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the risks/benefits 
of treatment alternatives. To minimize the systemic effects of orally inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, each 
patient should be titrated to the lowest dose that effectively controls his/her symptoms. The potential effect of AEROSPAN on growth rates in 
children was assessed in a 52 week randomized, placebo controlled study conducted in 242 prepubescent children age 4 to 9.5 years (145 
males, 97 females) with mild persistent asthma. Treatment groups were AEROSPAN 160 mcg twice daily and placebo. Growth velocity was 
estimated for each patient using the slope of the linear regression of height over time using observed data in the intent to treat population who 
had at least 3 height measurements. The mean growth velocities were 6.19 cm/year in the placebo group and 6.01 cm/year in the AEROSPAN 
treated group (difference from placebo -0.17 cm/year; 95% CI: -0.58, 0.24). 

Efficacy of Flunisolide HFA: 
The efficacy of AEROSPAN Inhalation Aerosol has been studied in two double-blind, parallel, placebo-and active-controlled clinical trials of 
12 weeks duration involving more than 1250 patients, one in adults and adolescents 12 years of age and older, and one in patients 4-11 years 
of age. In adults and adolescents, efficacy was evaluated in patients previously treated with inhaled corticosteroids. In children 6 to 11 years 
of age, efficacy was evaluated in patients previously treated with bronchodilators alone or inhaled corticosteroids. Both trials had a 2- week 
run-in period followed by a 12-week randomized treatment period. During the run-in period all patients received flunisolide CFC inhalation 
aerosol 500 mcg twice daily. Patients were then randomized to double-blind treatment with different doses of AEROSPAN Inhalation 
Aerosol or flunisolide CFC inhalation aerosol and monitored for lung function changes to see if they maintained, improved, or lost stability. 
Baseline was assessed at the end of the run-in period. The primary endpoint was the change from baseline in percent predicted FEV1 after 12 
weeks treatment.  
Adult and Adolescent Patients 12 Years of Age and Older: Efficacy was evaluated in 669 asthma patients, 12 to 78 years of age, including 
88 patients 12-17 years of age and 581 patients 18 years and older. Mean FEV1 at screening was 2.44 L and mean FEV1 at baseline was 2.72 
L following the 2-week run-in period. Patients were randomized to AEROSPAN Inhalation Aerosol 80 mcg, 160 mcg or 320 mcg twice daily, 
flunisolide CFC inhalation aerosol 250 mcg, 500 mcg, or 1000 mcg twice daily, or placebo. Change from baseline in percent predicted FEV1 
over 12 weeks treatment demonstrated that placebo patients deteriorated 4.3% from baseline after 12 weeks of treatment, whereas patients 
treated with AEROSPAN Inhalation Aerosol 160 mcg or 320 mcg twice daily maintained FEV1 over the course of the study. Results for the 
comparison to placebo were statistically significant for the 160 and 320 mcg twice daily AEROSPAN Inhalation Aerosol doses (see Figure 
1), but not for the 80 mcg dose. Secondary endpoints of AM peak expiratory flow rate, AM and PM asthma symptoms, nocturnal awakenings 
requiring a β2 agonist, and as needed use of inhaled β2 agonists showed differences from baseline favoring AEROSPAN Inhalation Aerosol 
over placebo. AEROSPAN Inhalation Aerosol and flunisolide CFC inhalation aerosol gave comparable results. 
Pediatric Patients 4 to 11 Years of Age: The trial enrolled 583 asthma patients, 4 to 11 years of age, although the primary efficacy 
parameter was evaluated only in the population of 513 patients 6 to 11 years of age. In these patients, the mean FEV1 at screening was 81.2% 
predicted, and the mean FEV1 at baseline following a two week run-in period was 87.5% predicted. Patients were randomized to

AEROSPAN Inhalation Aerosol 80 mcg or 160 mcg twice daily, flunisolide CFC inhalation aerosol 250 mcg or 500 mcg twice daily, or 
placebo. Change from baseline in percent predicted FEV1 over 12 weeks in patients 6 years of age and older demonstrated that placebo 
patients deteriorated 4.0% from baseline after 12 weeks of treatment; whereas patients treated with AEROSPAN Inhalation Aerosol 80 mcg 
or 160 mcg twice daily maintained FEV1 over the course of the study. Results for the comparison to placebo were statistically significant for 
the 80 mcg and 160 mcg doses of AEROSPAN Inhalation Aerosol, but there was no added benefit for the 160 mcg BID dose over the 80 mcg 
BID dose (see Figure 2). AEROSPAN Inhalation Aerosol and flunisolide CFC inhalation aerosol gave comparable results in patients 6 years 
of age and older. 

Rational for lung function as primary endpoint 
We are using change in lung function parameters (FEV1, FEF25-75%  from spirometry, R5, R5-R20, AX, Fres from IOS) as a means of assessing 
response as this provides an objective means of demonstrating improvement in both large and small airways.  FEV1 is a well-established parameter in 
assessing lung function and overall asthma control while FEF25-75% is recognized for its ability to determine small airway obstruction. 14   IOS is an 
emerging pulmonary function test using sound waves reflected down the pulmonary airway and back designed to assess airway parameters in an effort 
independent fashion.  While the details of its full clinical use is beyond the scope of this article, there are several recent review articles that provide a 
detailed discussion of the utility of IOS.15,16 One key attribute of IOS is that data suggests it may be more sensitive in detecting changes in the small 
airways than traditional spirometry.17-20  Lung function is routinely used in practice as a means of assessing control and thus these findings will be readily 
applicable to the clinician. While the pivotal trials of Aerospan looked only at FEV1 changes ( a measure of large airway dysfunction), our study proposes 
to look into small airway function as well. 

Secondary endpoints 
Secondary endpoints include asthma symptom control as defined by the standardized asthma control test (ACT).  We will also examine the 
number of corticosteroid courses, ED visits, and admissions patients in each group has over the study period.

STUDY RATIONALE 
Studies involving the efficacy of flunisolide have primarily been done on the older CFC formulation as discussed above.  In addition, none of 
these studies were targeted at asthma patients specifically with small airway disease.  Our goal is to provide greater clarity on the effect of 
HFA flunisolide at different doses in this unique patient population as HFA flunisolide has a smaller particle size than its CFC predecessor 
and thus improved deposition in the targeted areas.

STUDY DESIGN 

Study Overview 
This is a single center, open label, parallel group trial comparing the efficacy of two different strengths of HFA flunisolide on lung function in 
asthma patients with small airway disease. We will enroll approximately 50 pediatric patients (ages 6-18, see discussion on sample size 
below) with mild to moderate asthma based upon the National Heart, Lung, and Blood Institute asthma guidelines.21  These patients will be 
recruited from new patients presenting to a pediatric pulmonary clinic as well as from general pediatric clinics associated with the University 
of Louisville, School of Medicine. Patients will have been steroid-naïve for at least four weeks. Prior to enrollment, patients will have 
demonstrated small airway disease based on pre-bronchodilator FEF 25-75% of less than 65% predicted.22  Patients will be randomized to 
receive flunisolide at either 80mcg twice a day or 160mcg twice a day with every other consecutive patient receiving alternating therapy 
(Figure 1).  Prior to starting therapy, baseline IOS and spirometry pre and post bronchodilator (BD) will be obtained (Table 1).  Patients will 
be randomized as described above and will be followed up at six weeks.  At that point, repeat IOS and spirometry will be obtained again.  

Primary Efficacy Endpoint 
The average change in FEV1 and FEF25-75% measured by spirometry at baseline visit and again 6 weeks later as well the average change in 
R5, Area of Reactance (AX), and X5 between the two visits as measured by IOS. 

Secondary Efficacy Endpoints 
The number of protocol-defined asthma exacerbations requiring treatment with oral steroids between the two groups will be monitored.  We 
will also track frequency of albuterol use for acute symptoms, number of emergency room visits and hospital admissions for acute asthma 
exacerbations between the two groups. 

Safety Evaluations 
Rates of adverse events, withdrawal, adherence to treatment, and frequency of exacerbations; and resting respiratory rate and room air oxygen 
saturations over the 6 week treatment period, between patients in each treatment group. As we are using an FDA-approved drug for age-
appropriate population, and with approved dosages, we anticipate no major safety issues.

STUDY TREATMENTS 

Method of Assigning Subjects to Treatment Groups 
We will use a block randomization scheme to promote balance at the end of the study. Block randomization ensures that after each block of 
individuals are enrolled in the study (n individuals in total); an equal number of individuals will be assigned to each group (n/2 individuals in 
each group). We will use random block sizes of 8-12. Data about grouping will be kept by study coordinator in a secure, locked location in 
the clinic.  A password protected electronic database will also be created to store patient data in which will be kept on an encrypted, password 
protected computer. 

Test Formulation 
Subjects will be randomized equally to receive HFA Flunisolide 80mcg (AEROSPAN Inhalation Aerosol, MEDA Pharmaceuticals, Somerset, 
NJ) 1 inhalation BID or HFA Flunisolide 80mcg 2 inhalations BID.  All inhalations will be delivered using the built-in spacer device without 
any other attached devices, holding chambers, spacers, or masks.  Patients will be fully instructed on how to administer the medication 
exactly according to manufacturer’s specifications as discussed in the package insert.   
7.2.1 Packaging and Labeling 
As this is an open label study, patients will be given the device in standard packaging from MEDA Pharmaceuticals. 
7.2.2 Handling/Dispensing 
Study Test Drug will be distributed by MEDA Pharmaceuticals to the clinic site. Albuterol sulfate (PROAIR HFA, TEVA Respiratory, Inc, 
Sellersville, PA) will be dispensed to each patient at the time of enrollment. 
7.2.3 Dosage/Dosage Regimen 
Flunisolide HFA: Subjects will be instructed to administer Study Drug with one or two inhalations twice a day depending on the group per 
the manufacturer’s specifications as discussed in the package insert. 
Albuterol: In order to standardize each participant’s rescue therapy for acute symptoms, each enrollee will be provided with albuterol sulfate 
for breakthrough symptoms.

7.2.5 Storage 
Study Drug and albuterol sulfate should be stored in the site pharmacy in a secure location at room temperature/humidity. 

Study Medication Accountability 
An accurate and current accounting of the dispensing and return of Study Drug for each subject will be maintained on an ongoing basis by a 
member of the study site staff.  The number of doses of Study Drug dispensed and returned by the subject will be recorded.  The study 
monitor will verify these documents throughout the course of the study. 

Measures of Treatment Compliance 
Parents of subjects will be asked to bring all used and unused Study Drug containers to each study visit.  Albuterol use can be documented via 
changes in the counter.

10 ADVERSE EXPERIENCE REPORTING AND DOCUMENTATION 
 Adverse Events 
An adverse event (AE) is any untoward medical occurrence in a clinical investigation of a patient administered a pharmaceutical product and 
that does not necessarily have a causal relationship with the treatment.  An AE is therefore any unfavorable and unintended sign, symptom or 
disease temporally associated with the administration of an investigational product, whether or not related to that investigational product.   
The Investigator will probe, via discussion with the subject, for the occurrence of AEs during each subject visit and record the information in 
the site’s source documents.  Adverse events will be recorded in the subject CRF.  Adverse events will be described by duration (start and 
stop dates and times), severity, outcome, treatment and relation to study medication, or if unrelated, the cause.  Again, as this is an FDA 
approved medication being used in approved ages with approved dosages, we do not anticipate significant AEs.  
AE Severity 
The National Cancer Institute’s Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0, should be used to assess and grade 
AE severity, including laboratory abnormalities judged to be clinically significant. The modified criteria can be found in the study manual.  If 
the experience is not covered in the modified criteria, the guidelines shown in 2 below should be used to grade severity.  It should be pointed 
out that the term “severe” is a measure of intensity and that a severe AE is not necessarily serious. 
Table 2.  AE Severity Grading 
Severity (Toxicity Grade) 
Description 
Mild (1) 
Transient or mild discomfort; no limitation in activity; no 
medical intervention or therapy required. The subject may be 
aware of the sign or symptom but tolerates it reasonably well. 
Moderate (2) 
Mild to moderate limitation in activity, no or minimal medical 
intervention/therapy required. 
Severe (3) 
Marked limitation in activity, medical intervention/therapy 
required, hospitalizations possible. 
Life-threatening (4) 
The subject is at risk of death due to the adverse experience as it 
occurred. This does not refer to an experience that hypothetically 
might have caused death if it were more severe.

 Serious Adverse Experiences (SAE) 
An SAE is defined as any untoward medical occurrence that at any dose: 
•Results in death 
•Is considered life threatening (i.e., in the view of the investigator the adverse experience places the subject at immediate risk of death 
from the reaction, as it occurred; it does not include a reaction that, had it occurred in a more severe form, might have caused 
death) 
•Requires hospital admission or prolongation of an existing hospitalization 
•Results in persistent or significant disability/incapacity (i.e., a substantial disruption of a person’s ability to conduct normal life 
functions) 
•Is a congenital anomaly/birth defect 
•Is an important medical event (i.e., when based upon appropriate medical judgment, the adverse experience may jeopardize the 
subject and may require medical or surgical intervention to prevent one of the above listed outcomes) 
10.2.1 Serious Adverse Experience Reporting 
All SAEs that occur after informed consent is obtained until the end of subject’s participation in the study (whether Test Drug related or not) 
will be documented in an SAE Report.  All SAEs will be reviewed by the investigator.

If only a partial SAE report is available, preliminary information will be documented on an SAE Report form, reviewed by the investigator, 
and reported to the PI within one business day of learning of the event.  When additional relevant information is available, this information 
will be submitted promptly on a new SAE Report form. 
Reporting of SAEs to the Independent Review Board (IRB) will be performed by the investigator in accordance with the standard operating 
procedures and policies of the IRB.   
 Medical Monitoring 
The on-call medical monitor should be contacted directly at the following number to report medical concerns or questions regarding safety:   
• Medical Monitor’s Pager:   (502) 478-0074 
11 SCREEN FAILURES AND RE-SCREENING OF SUBJECTS 
Subjects who fail to meet eligibility criteria at either the Screening visit or at the Baseline visit will be classified as screen failures and will not 
be randomized.  Subjects who fail eligibility at the Baseline visit may repeat a Baseline visit, following resolution of failed eligibility criteria 
as applicable, within the 56 day window following the Screening visit. If the 56 day window is exceeded, the subject will be classified as a 
screen failure, but can be re-consented and re-screened at a later date. 
12 SUSPENSION OF STUDY DRUG, WITHDRAWALS, EARLY TERMINATION PROCEDURES, AND SUBJECT 
REPLACEMENT 
 Discontinuation of Study Drug, Subject Withdrawals, Early Termination Procedures  
A subject may permanently discontinue study drug at any time if the subject, the site investigator, or the Sponsor feels that it is not in the 
subject’s best interest to continue.  If a subject discontinues treatment due to an adverse event, the subject will be followed and treated by the 
Investigator until the abnormal parameter or symptom has resolved or stabilized.  If study drug is permanently discontinued, the participant 
should be encouraged to remain in the study and to complete all study visits and procedures,  

The following is a list of possible reasons for discontinuation of study drug or withdrawal. Note that in the case of the second two reasons, the 
participant should be encouraged to complete the remaining study visits rather than withdraw: 
♦ subject withdrawal of consent  
♦ subject is not compliant with study procedures 
♦ adverse event 
♦ study drug intolerance

 Replacement of Subjects 
Subjects who withdraw from the study will not be replaced.   
13 PROTOCOL VIOLATIONS 
A protocol violation occurs when the investigator fails to adhere to significant protocol requirements affecting the inclusion, exclusion, 
subject safety and primary endpoint criteria. Protocol violations for this study include, but are not limited to, the following: failure to meet 
inclusion/exclusion criteria, or incorrectly following protocols laid out in this document. The Principal Investigator will determine if a 
protocol violation will result in subject withdrawal. 
When a protocol violation occurs, it will be discussed with the investigator and a Protocol Violation Form detailing the violation will be 
generated. This form will be signed by the Investigator. A copy of the form will be filed in the site’s regulatory binder. 
14 DATA SAFETY MONITORING 
As this is an FDA approved drug being used in approved populations at approved doses, the elements listed under “safety evaluations” as 
above will be tracked by the PIs but no formal data safety review board will be in place. 
15 STATISTICAL METHODS AND CONSIDERATIONS 
Prior to the analysis of the data, a detailed Statistical Analysis Plan (SAP) will be written describing all analyses that will be performed.  The 
SAP will contain any modifications to the analysis plan described below. 
 Analysis of Physiologic Effects (Lung Function) 
The primary goal of the current study is to determine the effects of  Aerospan on lung function in children with small airway obstruction. 
Participants recruited into this randomized parallel group study will be randomly assigned to either receive (1) 80 mcg of Aerospan twice a 
day or (2) 160 mcg of Aerospan twice a day, during the six-week study period. Outcomes will be measured at baseline and at six-week 
follow-up as described above.  
First we will start with straightforward tests for differences among the two groups to test if our randomization scheme was successful. 
Analysis of Variance (ANOVA) techniques will be used to test for difference among continuous variables, while Kruskal-Wallis, Fischer’s 
Exact Tests and Wilcoxon methods will be used to test for differences among categorical variables.  
The primary endpoint will be changes in outcomes, over time, from baseline to six-week follow-up. The change in scores from baseline to 
six-week follow-up will initially be compared using paired t-tests and Chi-squared tests for trend. Repeated measurements will be analyzed 
using generalized linear mixed-effects regression modeling (GLMM) techniques. For continuous outcomes (e.g., FEV1, FEF 25-75%, Fres, 
X5, AX, R5-R20.) the identity link function and normal distribution will be used. For count data (e.g., use of Beta-agonists, episodes of

coughing, episodes of wheezing, etc.) the log link function and the Poisson distribution will be used. If we dichotomize outcomes (e.g., a 
Beta-agonist was used, coughing occurred, etc.) the logit link function and Bernoulli distribution will be used. Statistical analyses will be 
performed using SAS® Version 9.3 (SAS Institute Inc., Cary, NC). 
 Sample Size 
Based on our preliminary studies, we anticipate that 10% of all potential participants will not be eligible and/or willing to participant; and that 
10% of the eligible/willing participants will be lost to follow-up. Therefore, we will recruit a total of n=50 individuals for the current study. 
This is a feasible sample size for the research team to recruit and enroll in the current study. Power calculations were based on the anticipated 
total sample size (n=40) that will be available for complete analysis.  
We will develop separate mixed-effects general linear models for each of the continuous outcomes. From the anticipated sample size (n=40) 
the study has 86% power to detect a 10% main effect of each treatment for each outcome, our anticipated effect size given preliminary 
studies. When using count data the study has 94% power to detect a 10% decrease in the rate of outcomes (coughing, wheezing, etc.), our 
anticipated change in the rate. Using the dichotomized version of some outcomes, this study has 80% power to detect on odds ratio of 1.32 
with a two sided α=0.05 (n=40). Therefore, we have more than sufficient numbers of participants in each comparison group.   
16 DATA COLLECTION, RETENTION AND MONITORING 
 Data collection 
Data that will be collected during the study include: enrollment and randomization information, spirometry/IOS data, other subject data 
collected during the study visit, and asthma controls scores.  This data will be kept in a secure, locked filing cabinet in the pediatric 
pulmonary clinic office.   
An electronic database of data will be created using Microsoft Excel.  This database will be encrypted, password protected, and stored 
exclusively on a password protected computer in the pediatric pulmonary clinic.   
 Availability and Retention of Investigational Records 
The Investigator must make study data accessible to the IRB upon request.  A file for each subject must be maintained that includes the 
signed Informed Consent, HIPAA Authorization and copies of all source documentation related to that subject.  The Investigator must ensure 
the reliability and availability of source documents from which the information on the CRF was derived.  All study documents (subject files, 
signed informed consent forms, copies of CRFs, Study File Notebook, etc.) must be kept secured for a period of three years.

17 ADMINISTRATIVE, ETHICAL, REGULATORY CONSIDERATIONS 
The study will be conducted according to the Declaration of Helsinki, Protection of Human Volunteers (21 CFR 50), Institutional Review 
Boards (21 CFR 56), and Obligations of Clinical Investigators (21 CFR 312). 
To maintain confidentiality, all lung function data, evaluation forms, reports and other records will be identified by a coded number and 
initials only.  All study records will be kept in a locked file cabinet and code sheets linking a subject’s name to a subject identification number 
will be stored separately in another locked file cabinet.  Clinical information will not be released without written permission of the subject.  
The Investigator must also comply with all applicable privacy regulations (e.g., Health Insurance Portability and Accountability Act of 1996, 
EU Data Protection Directive 95/46/EC). 
17.1.1 Protocol Amendments 
Any amendment to the protocol will be written by the Study Principal Investigators. 
A protocol amendment intended to eliminate an apparent immediate hazard to subjects may be implemented immediately, provided the IRBs 
are notified within five working days. 
17.1.2 Institutional Review Boards and Independent Ethics Committees 
The protocol and consent form will be reviewed and approved by the IRB.  Serious adverse experiences regardless of causality will be 
reported to the IRB in accordance with the standard operating procedures and policies of the IRB, and the Investigator will keep the IRB 
informed as to the progress of the study.  The Investigator will obtain a list of IRB members or other assurance of compliance with 
regulations. 
Any documents that the IRB may need to fulfill its responsibilities (such as protocol, protocol amendments, Investigator’s Brochure, consent 
forms, information concerning subject recruitment, payment or compensation procedures, or other pertinent information) will be submitted to 
the IRB.  The IRBs written unconditional approval of the study protocol and the informed consent form will be in the possession of the 
Investigator before the study is initiated.   
Protocol and/or informed consent modifications or changes may not be initiated without prior written IRB approval except when necessary to 
eliminate immediate hazards to the subjects or when the change(s) involves only logistical or administrative aspects of the study.  Such 
modifications will be submitted to the IRB/IEC and written verification that the modification was submitted and subsequently approved 
should be obtained.   
The IRB must be informed of revisions to other documents originally submitted for review; serious and/or unexpected adverse experiences 
occurring during the study in accordance with the standard operating procedures and policies of the IRB; new information that may affect

completed. 
17.1.3 Informed Consent Form  
Informed consent will be obtained in accordance with the Declaration of Helsinki, ICH GCP, US Code of Federal Regulations for Protection 
of Human Subjects (21 CFR 50.25[a,b], CFR 50.27, and CFR Part 56, Subpart A), the Health Insurance Portability and Accountability Act 
(HIPAA, if applicable), and local regulations. 
The Investigator will prepare the informed consent form and HIPAA authorization and provide the documents to the IRB.  The consent form 
generated by the Investigator must be approved by the IRB/IEC.  The written consent document will embody the elements of informed 
consent as described in the International Conference on Harmonization and will also comply with local regulations.  
A properly executed, written, informed consent and HIPA authorization will be obtained from the legal guardian of each subject prior to 
entering the subject into the trial.  Information should be given in both oral and written form and subjects’ legal representatives must be given 
ample opportunity to inquire about details of the study.  A copy of the signed consent form will be given to the legal representative of the 
subject and the original will be maintained with the subject’s records.
