Phase 1 Study of Levocetirizine

August 1, 2017 updated by: GlaxoSmithKline

A Single Blind, Randomized, Single Oral Dose Study to Compare the Oral Disposition of Levocetirizine When Given Alone (5mg) or as the Racemate (Cetirizine 10mg), and to Investigate the Safety and Tolerability and the Pharmacokinetics of Levocetirizine and Cetirizine, Following a Single Dose in Healthy Japanese Male Subjects

This is a single center, single blind, single dose, randomized, partial cross-over study to confirm bioequivalence between levocetirizine and cetirizine.

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.

Study Type

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

20 years to 64 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

  2. The subject has an allergy for any drug or idiosyncrasy.
  3. The subject has a history of allergic rhinitis.
  4. The subject has a history or presence of clinically significant gastrointestinal, hepatic or renal disease or other condition known to interfere with absorption, distribution, metabolism or elimination of drugs.

  6. The subject has participated in a clinical study with an investigational or a non-investigational drug or device during the previous 4 months.
  7. The subject has a history or current conditions of drug abuse or alcoholism.
  8. History of regular alcohol consumption exceeding on average, 14 drinks/week (1 drink = 150mL of wine or 360mL of beer or 45mL of 80 proof distilled spirits).
  9. The subject is positive for urine drug screening.

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.
