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.

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.

    2. A medical history which, in the opinion of the investigator, might impact the validity of the study results and may require pharmacotherapy or prevent the subject from finishing the study.
    3. Oral surgery within 4 weeks of dosing, dental work or extractions within 2 weeks of dosing, or presence of any clinically significant (as determined by the principal investigator) oral pathology including lesions, sores or inflammation.

  • Subject has participated in another clinical study or received an investigational drug within 30 days of the first study session or previously participated in this study.
  • Subject has donated or experienced significant blood loss within 56 days of Visit 2, donated plasma within 7 days of Visit 2, or has a hemoglobin value of <12.0g/dL.
  • Subject has been treated with any known enzyme-altering agents (e.g., barbiturates, phenothiazines, cimetidine, theophyllines) within 30 days prior to the first study session.
  • Subject has used any nicotine replacement therapy within 21 days prior to the first study session.
  • Subject has used any over-the-counter (OTC) medication or herbal supplements within 48 hours prior to administration of study treatment.
  • Subject has used any prescription medication within 14 days prior to each study session, excluding hormonal contraceptive or hormone replacement therapy.
  • Subject is a member of the study site staff or an employee of the sponsor.

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
Time Frame
To compare the 2mg prototype lozenge to the 2mg standard lozenge in terms of AUC0-infinity, tmax, t½, and Kel, and likewise 4mg prototype lozenge to 4mg standard lozenge.
Time Frame: 12 hours
12 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
Time Frame
• To compare the 2mg prototype lozenge to the 2mg standard lozenge in terms of AUC0-infinity, tmax, t½, and Kel, and likewise with the 4mg prototype lozenge to 4mg standard lozenge;
Time Frame: 12 hours
12 hours
• To evaluate the safety of the 2mg and 4mg prototype lozenges.

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
