Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single center, open-label, 2-period crossover study. The study consists of a screening visit followed by a treatment period comprising 2 treatment visits. The treatment period visits will be separated by a 4 to 14-day washout period. Eligible patients will be kept overnight prior to each treatment period.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

4 years to 11 years (CHILD)

Accepts Healthy Volunteers

No

  5. Any patient being treated with inhaled corticosteroids (ICS) must be on a lowdose regimen (200 mcg or less of fluticasone propionate per day or equivalent), which has been stable for at least 4 weeks prior to the SV and which is expected to be maintained for the duration of the study
  6. Has required less than 4 inhalations per week of a rescue bronchodilator (on average) for the 4 weeks preceding the SV

  7. Has the ability to withhold inhaled albuterol for at least 72 hours preceding each Treatment Visit (TV).

    • Other criteria apply, including must weigh at least 45 pounds

Exclusion Criteria:

  1. A known hypersensitivity to albuterol or any of the excipients in the inhaler formulations (lactose, ethanol, etc.)
  2. Participation (receiving study drug) in any investigational drug trial within the 30 days preceding the SV or planned participation in another investigational drug trial at any time during this trial
  3. History of severe milk protein allergy
  4. Proneness to orthostatic dysregulation, syncope, or blackouts
  5. History of a respiratory infection or disorder (including, but not limited to bronchitis, pneumonia, acute or chronic sinusitis, otitis media, influenza) that has not resolved within 2 weeks preceding the SV.
  6. History of life-threatening asthma or that is defined for this protocol as an asthma episode that required intubation and/or was associated with hypercapnea, respiratory arrest or hypoxic seizures

  7. Any asthma exacerbation requiring systemic corticosteroids within 3 months of the SV. A patient must not have had any hospitalization for asthma within 6 months prior to the SV.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Area under the plasma albuterol concentration-time curve
Time Frame: Time 0 to the last detectable plasma albuterol concentration measured up to 10 hours post-dose (AUC0-t)
Blood samples for plasma albuterol concentration determination will be drawn 5 (±2) minutes prior to dosing and at 30 (±2), 60 (±5), 120 (±10), 360 (±10), and 600 (±10) minutes after the completion of dosing.
Time 0 to the last detectable plasma albuterol concentration measured up to 10 hours post-dose (AUC0-t)
Maximum observed plasma albuterol concentration (Cmax)
Time Frame: From baseline to up to 10 hours post dose
Blood samples for plasma albuterol concentration determination will be drawn 5 (±2) minutes prior to dosing and at 30 (±2), 60 (±5), 120 (±10), 360 (±10), and 600 (±10) minutes after the completion of dosing.
From baseline to up to 10 hours post dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pharmacodynamic Effect on Vital Signs
Time Frame: From baseline to up to 6 hours post dose

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
