A Two-Part Study to Determine: Best Medication Formulation and Food Effect

October 6, 2008 updated by: GlaxoSmithKline

A Two-Part Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Four MR Formulations and Food Effect of GW427353 (Solabegron) in Healthy Adult Subjects

This is a two-part study. Part 1 is designed to find the best modified release formulation of GW423753; Part 2 is designed to use the selected formulation(s) from Part 1 to find out if food affects the way the medication is processed by the body.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Healthy males & females
  • Part 1 ages 18-60
  • Part 2 ages 18-50 & 65-80
  • Within normal weight range given your height
  • Negative urine drug and alcohol test
  • Willing to follow all study procedures

Exclusion Criteria:

  • Any clinically relevant abnormality identified on the screening physical examination, clinical laboratory tests, 12-lead ECG, or any other medical condition or circumstance making the subject unsuitable for participation in the study based on the Investigator's assessment.
  • Subjects with either a blood pressure measurement > 150/90 mmHg, or a history of coronary disease AND a blood pressure > 140/90 mmHg, at screening.
  • History of drug or other allergy, which, in the opinion of the Investigator, contraindicates their participation.
  • Regular alcohol consumption averaging >/7 drinks/week for women or >/ 14 drinks/week for men (1 drink = 5 ounces of wine or 12 ounces of beer or 1.5 ounces of hard liquor) within 6 months of the first dose of study medication.
  • Positive urine drug, alcohol or serum pregnancy test at screening and prior to dosing in each study session.
  • Positive for hepatitis C antibody, hepatitis B surface antigen or HIV at screening.
  • Treatment with an investigational drug within 30 days or 5 half-lives (whichever is longer) prior to administration of study medication.
  • Use of prescription or non-prescription drugs within 7 days or 5 half-lives (whichever is longer) prior to administration of study medication and during the study. By exception, use of acetaminophen at doses of ≤ 2 grams per day, the use of contraceptives (oral, depots, patches, etc.) and anti-hypertensive medications will be permitted.
  • Use of vitamins or herbal/dietary supplements within 7 days prior to administration of study medication and during the study.
  • Subject is unable and/or unwilling to adhere to Lifestyle Guidelines
  • Subjects who have donated more than 500 mL of blood or plasma within 56 days prior to administration of study medication.
  • An unwillingness on the part of male volunteers to abstain from sexual intercourse with pregnant or lactating women; or an unwillingness to use a condom and another form of contraception (e.g., IUD, birth control pills taken by female partner, diaphragm with spermicide) if engaging in sexual intercourse with a woman who could become pregnant from the time of the first dose of study medication until completion of follow-up procedures.
  • Pregnant or lactating woman. A pregnancy test will be performed for all women at screening and prior to each dosing session to confirm eligibility.
  • The subject has a known hypersensitivity or idiosyncratic reaction to any drug chemical related to this study.

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
Absorption rate of the tablet formulations as measured several times by blood draws (over 48-hour period) during the Part 1 under fed conditions and Part 2 under fed vs. fasted conditions

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
Toleration of the formulations after single and repeat doses (over 7-day period)
Part 1: Safety and tolerability assessments will include data from spontaneous adverse event reporting, vital signs, 12-lead ECGs, physical examinations, and safety laboratory tests.
Part 2: Safety and tolerability assessments will include data from spontaneous adverse event reporting, vital signs, 12-lead ECGs, physical examinations, and safety laboratory tests.
Part 2: The secondary pharmacokinetic parameters will be the AUC, Cmax, Tmax, and T1/2 following repeat oral dosing of Solabegron, as the data permit.

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.
