About this study
Official title: Evaluation of the Sensitivity of Pharmacokinetics to Differences in the Aerodynamic Particle Size Distribution of Three Different Formulations of Fluticasone Propionate Dry Powder Inhalers
When a drug company first develops a drug, the company has to show the Food and Drug Administration (FDA) that the drug is safe and effective. If FDA concludes that the drug is safe and effective, FDA approves the drug. The company can then sell the drug, which the company does using "trade name." Only the drug company that developed the "trade name" drug is allowed to sell it. However, other drug companies can create their own version of the "trade name" drug, which usually happens after the patents for the "trade name" product run out. These drugs, often called "generic drugs," potentially will be less expensive for the patient. In order to sell generic drugs, drug companies must show that their generic version is the same as the "trade name" drug in a number of ways. For example, they generally have to show that their product is intended to be used to treat the same diseases or conditions, that it has the same label, and that the product has the same active ingredient as the "trade name" drug. The generic company also has to show that generic product is "bioequivalent" to the trade name drug, meaning that the generic product gets to the part of the body where the drug works at the same rate that the trade name drug does. How to show how much drug gets to the part of the body where it works, and how fast, depends on the type of product the drug is. The primary aim of this research study is to aid the FDA in finding methods to ensure that the versions of generic drugs that are inhaled (for example, drugs used to treat asthma) are bioequivalent to the trade name drug. As a part of the research study, pharmacokinetic (PK) studies (studies measuring drug levels in the blood over time after inhalation) will be done using three different versions of fluticasone propionate (FP, a drug routinely used in asthmatic patients) administered using a dry powder inhaler (DPI, an inhalation device that delivers the drug as a dry powder). The results from this study will help FDA ensure that generic products are the same as the trade name drugs.

Formulation Development
The aim of the pharmaceutical development was to manufacture three Dry powder Inhalation (DPI) formulations containing Fluticasone Propionate in an Plastiape Monodose DPI device, which provide distinct in vitro deposition patterns on a Next Generation Impactor. NGI is a high performance cascade impactor used to characterize aerosol particles by particle size. It is desirable to develop three formulations with the same emitted dose (ED), impactor size mass (ISM) but different mass median aerodynamic diameter (MMAD). Meeting these design criteria for the formulations would help to see if pharmacokinetic parameters are sensitive to regional differences in drug deposition whilst having the dose deposited in the lung from different formulations being the same.The three formulation developed are labeled Fluticasone Propionate Drug formulation 1 through 3.
Study Procedures and scheduling
The study is comprised of 5 visits in total - a screening visit and 4 treatment visits. At least 5 days should lapse between the treatment visits.
Screening Visit During the screening visit, the inclusion and exclusion criteria will be reviewed to ensure the volunteer is appropriate for the study. The informed consent will be reviewed with the volunteer by a member of the study team and the volunteer will be encouraged to ask questions to ensure the volunteer has a good understanding of the study. If the volunteer is eligible and agrees to participate, the volunteer will be asked to sign the informed consent form prior to any study specific procedures including randomization. After the volunteer signs the informed consent, the volunteer will be interviewed and demographic data, medical history and concomitant medications will be collected and recorded. A physical examination will be performed after the vital sign measurements are obtained. A pregnancy test for female volunteers will be obtained. Spirometry testing and inhalation training will be performed by a qualified study clinician/investigator to ensure the suitability of volunteers. Laboratory tests including a Complete Blood Count (CBC), urinalysis and metabolic panel will be collected via venipuncture and processed in the lab. Screening tests will be performed within 14 days of treatment visit 1 and no later than 2 days before treatment visit 1. All screening results will be evaluated by the study clinician/investigator against the inclusion/exclusion criteria to confirm the eligibility of the volunteers.
Inhalation training: Inhalation training will be performed by a qualified study clinician at the screening visit and at each study visit. The training will be accomplished by instructions and subsequent inhalation via training devices containing empty capsules. The instructions on how to use the device correctly are similar to the Foradil Aerolizer DPI product information label. (http://www.rxlist.com/foradil-drug/medication-guide.htm )
Treatment Visits 1, 2, 3 and 4 Eligible volunteers will be asked to return for treatment visit 1. A minimum period of 5 days should lapse between the subsequent treatment visits. Each treatment visit is scheduled for 28 hours over two days. The study will be conducted at the University of Florida (UF) CRC (Clinical Research Center). It is an outpatient study and the volunteer will be asked to come back the following day for the 24 hour blood sample. The volunteer will be asked to stay in an outpatient room during the treatment visit. The same activities are carried out at the other treatment visits.
At each treatment visit, eligibility criteria will be reviewed and confirmed to ensure volunteer is appropriate for study. Changes in medical history including concomitant medications will be documented. Vital signs will be obtained. Inhalation training will be provided to the volunteers as mentioned in the section above. An IV catheter will be inserted in a vein located in the forearm region of the volunteer. The IV catheter is used to avoid multiple pricks while collecting blood samples. The IV catheter is not used for the administration of the drug. The volunteer inhales 5 times from a given inhaler during each treatment visit. Each inhaler will be used only once and by only one volunteer to ensure the volunteer's safety from infectious agents. The schedule below summarizes the procedures performed at the screening visit and a single treatment visit.
Blood sample collection Blood samples will be drawn by inserting an indwelling catheter into the volunteer's median cubital vein in the forearm region. Blood samples will be taken 15 minutes prior to the dosing of the product (pre-dose sample) and 5, 10, 15, 20, 30, 45, 60 minutes, 1.5, 2, 3, 4, 6, 8, 10, 12, 14 and 24 hours post dosing. At each time point 9ml of blood sample will be collected of which the first 1ml will be discarded and the remaining 8 ml will be stored in a vacutainer tube for plasma preparation and storage.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
When a drug company first develops a drug, the company has to show the Food and Drug Administration (FDA) that the drug is safe and effective. If FDA concludes that the drug is safe and effective, FDA approves the drug. The company can then sell the drug, which the company does using "trade name." Only the drug company that developed the "trade name" drug is allowed to sell it. However, other drug companies can create their own version of the "trade name" drug, which usually happens after the patents for the "trade name" product run out. These drugs, often called "generic drugs," potentially will be less expensive for the patient. In order to sell generic drugs, drug companies must show that their generic version is the same as the "trade name" drug in a number of ways. For example, they generally have to show that their product is intended to be used to treat the same diseases or conditions, that it has the same label, and that the product has the same active ingredient as the "trade name" drug. The generic company also has to show that generic product is "bioequivalent" to the trade name drug, meaning that the generic product gets to the part of the body where the drug works at the same rate that the trade name drug does. How to show how much drug gets to the part of the body where it works, and how fast, depends on the type of product the drug is.

Study Procedures and scheduling
The study is comprised of 5 visits in total - a screening visit and 4 treatment visits. At least 5 days should lapse between the treatment visits.
Screening Visit During the screening visit, the inclusion and exclusion criteria will be reviewed to ensure the volunteer is appropriate for the study. The informed consent will be reviewed with the volunteer by a member of the study team and the volunteer will be encouraged to ask questions to ensure the volunteer has a good understanding of the study. If the volunteer is eligible and agrees to participate, the volunteer will be asked to sign the informed consent form prior to any study specific procedures including randomization. After the volunteer signs the informed consent, the volunteer will be interviewed and demographic data, medical history and concomitant medications will be collected and recorded. A physical examination will be performed after the vital sign measurements are obtained. A pregnancy test for female volunteers will be obtained. Spirometry testing and inhalation training will be performed by a qualified study clinician/investigator to ensure the suitability of volunteers. Laboratory tests including a Complete Blood Count (CBC), urinalysis and metabolic panel will be collected via venipuncture and processed in the lab. Screening tests will be performed within 14 days of treatment visit 1 and no later than 2 days before treatment visit 1. All screening results will be evaluated by the study clinician/investigator against the inclusion/exclusion criteria to confirm the eligibility of the volunteers.
Inhalation training: Inhalation training will be performed by a qualified study clinician at the screening visit and at each study visit. The training will be accomplished by instructions and subsequent inhalation via training devices containing empty capsules. The instructions on how to use the device correctly are similar to the Foradil Aerolizer DPI product information label. (http://www.rxlist.com/foradil-drug/medication-guide.htm )
Treatment Visits 1, 2, 3 and 4 Eligible volunteers will be asked to return for treatment visit 1. A minimum period of 5 days should lapse between the subsequent treatment visits. Each treatment visit is scheduled for 28 hours over two days. The study will be conducted at the University of Florida (UF) CRC (Clinical Research Center). It is an outpatient study and the volunteer will be asked to come back the following day for the 24 hour blood sample. The volunteer will be asked to stay in an outpatient room during the treatment visit. The same activities are carried out at the other treatment visits.
At each treatment visit, eligibility criteria will be reviewed and confirmed to ensure volunteer is appropriate for study. Changes in medical history including concomitant medications will be documented. Vital signs will be obtained. Inhalation training will be provided to the volunteers as mentioned in the section above. An IV catheter will be inserted in a vein located in the forearm region of the volunteer. The IV catheter is used to avoid multiple pricks while collecting blood samples. The IV catheter is not used for the administration of the drug. The volunteer inhales 5 times from a given inhaler during each treatment visit. Each inhaler will be used only once and by only one volunteer to ensure the volunteer's safety from infectious agents. The schedule below summarizes the procedures performed at the screening visit and a single treatment visit.
Blood sample collection Blood samples will be drawn by inserting an indwelling catheter into the volunteer's median cubital vein in the forearm region. Blood samples will be taken 15 minutes prior to the dosing of the product (pre-dose sample) and 5, 10, 15, 20, 30, 45, 60 minutes, 1.5, 2, 3, 4, 6, 8, 10, 12, 14 and 24 hours post dosing. At each time point 9ml of blood sample will be collected of which the first 1ml will be discarded and the remaining 8 ml will be stored in a vacutainer tube for plasma preparation and storage.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Fluticasone Propionate Formulation 1, Fluticasone Propionate Formulation 2 and Fluticasone Propionate Formulation 3 in people with Asthma, run by University of Florida at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 May 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area Under the Plasma Concentration-time Profile From Time 0 the Last Quantifiable Concentration (AUC0-last) With Dose Normalization (time frame: Day 1 of Periods 1, 2, 3, and 4: pre-dose (15 minutes prior to the dosing), and 5, 10, 15, 20, 30, 45, 60 minutes, 1.5, 2, 3, 4, 6, 8, 10, 12, 14 and 24 hours (+/- 1 hour) post-dose). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2024.
