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

The objective of this study was to evaluate the tolerability, safety, and pharmacokinetics of a single, inhaled dose of prochlorperazine (PCZ), administered as 1 or 2 puffs in healthy young volunteers.

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

18 years to 45 years (Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Subjects will be male or female subjects between the ages 18 to 45 years, inclusive in good general health as determined by medical history, physical examination, 12-lead ECG, spirometry, blood chemistry profile, hematology, urinalysis and in the opinion of the Principal Investigator.

Exclusion Criteria:

  • Subjects with a known history of allergy or intolerance to phenothiazines or related drugs or who have any disease, by history, physical examination, or laboratory abnormalities that in the investigator's opinion, would present undue risk to the subject, or may confound the interpretation of study results.

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
Time to Peak (Tmax)
Time Frame: 24 hours
Time from dose to peak prochlorperazine concentration
24 hours

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
Absolute Bioavailability of Inhaled Prochlorperazine
Time Frame: 24 hours
Absolute bioavailability of inhaled prochlorperazine via AUC infinity
24 hours
Dose Proportionality of Inhaled Prochlorperazine by Power Analysis
Time Frame: 24 hours
Dose proportionality by power analysis examines the linear regression of the log-AUC versus log-Dose on a by-patient basis across all doses administered. The slope and 90% confidence interval (CI) provide a clear, quantitative (best practices) assessment of the relationship of drug delivered to dose administered. The units on such analyses are generally those of slope (rise over run), with 1.000 being "perfect". Although any positive slope might be considered clinically useful, a 90% CI within the criteria of 0.800-1.250 may be considered a delivery system which is "as good as it gets".
